Answer:
If in football. Then Homer has made a total of 24 interceptions and 96 hits
Step-by-step explanation:
if we know that Homer has four times as many hits in baseball than interceptions that means how ever many interceptions he has its four times greater that that number so if he had 5 interceptions then you would do 5 x 4 and the number of hit would be 20 so if you already know the number of hits all together like we do you would divide by 5 cause the number of hits count as 4/5 and interceptions is 1/5 of that so we do 120/5 which gives us 24 and to find the number of hit we times that by 4 then we get 96 and to check our answer 96 + 24 = 120

A) 2
B) 4
C) 8
D) 12
Answer:
B
Step-by-step explanation:
All circles are similar and therefore proportional. C/C' is the ratio of Circle C to Circle C'. Since it is 0.75, this means that C is 75% of C'. We know that radius of C will also be 75% of the radiuc of C'. We can the radius because we know the diameter of Circle C is 6. The radius is therefore 3. 3 is 75% of 4. So r/r' or 3/4=0.75. r/ must be 4.

Coconut oil freezes at a higher temperature than cottonseed oil because 24.8 °C < −48.1 °C. Coconut oil freezes at a lower temperature than cottonseed oil because 24.8 °C < −48.1 °C. Coconut oil freezes at a higher temperature than cottonseed oil because 24.8 °C > −48.1 °C. Coconut oil freezes at a lower temperature than cottonseed oil because 24.8 °C > −48.1 °C.
Answer:
The correct answer is option (C).
Coconut oil freezes at a higher temperature than cottonseed oil because 24.8 > -48.1
Step-by-step explanation:
We have been given the freezing temperatures of cottonseed oil and coconut oil. The freezing temperature of cottonseed oil is -48.1 degree celsius and the same for coconut oil is 24.8 degree celsius.
We are supposed to compare the two freezing temperatures. We know that 24.8 is higher than -48.1, therefore, we can conclude that freezing temperature of coconut oil is higher than the freezing temperature of cottonseed oil because 24.8 is more than -48.1. Thus, correct answer is option (C).

Marisa painted 1/2 of her bedroom in 3/4 of a hour at this rate how long will it take her to paint the entire room
Answers
3/8 of an hour
8/3 of an hour
4/6 of an hour
6/4 of an hour
At the same rate, it would take Marisa 6/4 of an hour to paint the entire room. This is a ratio problem, specifically dealing with rates and proportional relationships.
Explanation:Since Marisa painted 1/2 of her room in 3/4 of an hour, to paint the entire room would take double that time. When you double 3/4, you get 6/4. Therefore, at the same rate, Marisa would need 6/4 of an hour to paint the entire room.
This problem is a basic ratio problem related to rates and proportional relationships, common topics in middle school math. The rate in this case is painting speed, half a room per 3/4 of an hour. Thus, when we double the room space to be painted (from half a room to a full room) we should also double the required time.

How do you set up an equation for this problem??
Answer:
2x + 7 = 3x - 5
Step-by-step explanation:
Since triangle RTS is isosceles, RT is congruent to RS. So you can set up the equation 2x + 7 = 3x - 5 to find x. Then you can input the value of x into 2x +7 or 3x - 5 to find the measure of the congruent sides.
In a certain bag of candies, 2/5 of the candies are grape flavored and 3/10 are lemon flavored. What fraction of the candies is either grape flavored or lemon flavored?
A. 1/10
B. 2/3
C. 7/10
To find the fraction of candies that are either grape or lemon flavored, we add the fractions representing each flavor: 2/5 for grape and 3/10 for lemon. After finding a common denominator, we get 4/10 + 3/10, yielding 7/10 of the candies being either grape or lemon-flavored.
To find the fraction of candies that are either grape-flavored or lemon-flavored, we need to add the fractions that represent each flavor. We are told that 2/5 of the candies are grape-flavored and 3/10 are lemon-flavored.
First, we need a common denominator to add these two fractions. The least common denominator for 5 and 10 is 10. We can convert 2/5 to a fraction with a denominator of 10 by multiplying both the numerator and denominator by 2. This gives us 4/10. Now we can add:
4/10 (grape flavored)
+ 3/10 (lemon flavored)
= 7/10 (either grape or lemon flavored)
Hence, the fraction of the candies that are either grape-flavored or lemon-flavored is 7/10.

Determine the rate of change of f , f(x)= 6x-5
Answer:
6
Step-by-step explanation:
the rate of change is given by the slope of the line
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
f(x) = 6x - 5 is in this form
with slope m = 6 ← rate of change
Answer:
6
Step-by-step explanation:
We are given the function f(x) = 6x-5 for which we have to determine its rate of change.
The rate of change is given by the slope of a line.
We know that the standard form of an equation of a line is given by:
y = mx + c
where m is the slope.
If we observe the given function, we can notice that is in the form y = mx + c where the slope (m) is 6.
Therefore, the rate of change for the function f(x) = 6x - 5 is 6.

On a piece of paper, graph y < 3/4 x+2 Then determine which answer matches the graph drew.
Step-by-step explanation:
Given inequality is [tex]y<\frac{3}{4}x+2[/tex].
To graph that inequality, first we need to graph the line [tex]y=\frac{3}{4}x+2[/tex]. Then shade it for the inequality symbol <.
Graphing line can be done using two points.
plug x=0 into [tex]y=\frac{3}{4}x+2[/tex], we get:
[tex]y=\frac{3}{4}*0+2=2[/tex]
Hence first point is (0,2)
Similarly plug any random number for x say x=4, we get:
[tex]y=\frac{3}{4}*4+2=5[/tex]
Hence first point is (4,5).
Now we just need to graph both points and join them by a dotted line. because we have < not <=.
Next part is to test for shading.
Which can be done using any test point which is not on the given line. Say (0,0)
plug x=0,y=0 into [tex]y<\frac{3}{4}x+2[/tex].
[tex]0<\frac{3}{4}*0+2[/tex]
[tex]0<0+2[/tex]
0<2
which is true, hence shading will be in direction of test point (0,0).
Hence final answer will be the choice which looks like the graph attached below;
The correct answer is 2. A dashed line with the shaded area below the line.
To graph y < 3/4 x + 2, first find the y-intercept, which is the point where the line crosses the y-axis.
This happens when x is 0, so the y-intercept is 2.
The slope of the line is 3/4, so for every 3 units you move up, you must also move 4 units to the right.
Start at the y-intercept and move 3 units up.
Then, move 4 units to the right.
Repeat this process until you have graphed a few points.
The line should continue in this direction forever.
The shaded area below the line represents the values of y that are less than 3/4 x + 2.
Here are the possible answers:
A solid line with the shaded area below the line.A dashed line with the shaded area below the line.A solid line with the shaded area above the line.A dashed line with the shaded area above the line.The correct answer is 2. A dashed line with the shaded area below the line.
The dashed line indicates that the inequality is not strict, meaning that the line is allowed to touch the shaded area.
The shaded area below the line indicates that the values of y that are less than 3/4 x + 2 are represented by the points below the line.

A. 12
B. 36
C. 48
D. 63
Answer:
Option B is correct
36 pizzas were topped with vegetables
Step-by-step explanation:
Let x be the number.
As per the statement:
At a pizzeria, the ratio of pizzas topped with meat to pizzas topped with vegetables was 4:3 on Saturday.
The ratio of pizza topped with meat to pizzas topped with vegetables = 4 : 3
then;
the number of pizza topped with meat = 4x
and
the number pizza topped with vegetables = 3x
It is also given that the pizzeria made a total of 84 pizzas that day.
[tex]\text{Total Pizzas} = \text{Number of pizzas topped with meat}+ \text{Number of pizzas topped with vegetables}[/tex]
Substitute the given values we get;
[tex]84 = 4x+3x[/tex]
Combine like terms;
[tex]84= 7x[/tex]
Divide both sides by 7 we get;
12 = x
The pizza were topped with vegetables = 3x = 3(12) = 36
therefore, 36 pizzas were topped with vegetables
Answer:
The correct answer is option B.
Step-by-step explanation:
The ratio of pizzas topped with meat to pizzas topped with vegetables was 4:3 on Saturday.
Let the pizza's topped with meat be 4x
Let the pizza's topped with vegetable be 3x
Total pizzeria made a Saturday = 84
4x + 3x = 84
7x = 84
x = [tex]\frac{84}{7}=12[/tex]
Pizza's topped with meat = 4x = 4 × 12 = 48
Pizza's topped with vegetable = 3x = 3 × 12 = 36

Using the letters in the word INNOVATIVE, find the number of permutations that can be formed using 4 letters at a time. Show your work or explain how you got your answer.
Answer:
Number of permutations = 5040
Step-by-step explanation:
We are given the word 'INNOVATIVE', that has total 10 letters.
Now, we are asked to form words using exactly 4 letters at a time i.e. out of 10 letters we are using 4.
Therefore, the number of permutations that can be formed using 4 letters are = P(10,4)
i.e. [tex]10_{P_{4} }[/tex]
= [tex]\frac{10!}{(10-4)!}[/tex]
= [tex]\frac{10!}{6!}[/tex]

Step-by-step explanation:
a. Given => m∠5 = 40°
b. Given => m∠2 = 140°
c. Same Side Interior Angle Theorem => The same side interior angles must add up to 180°, which in this case, it does. m∠4 and m∠2 are alternate interior angles, and so there measurements are the same. 180 - 140 = 40
d. Both angles are part of the "same-side interior angles", which means that there measurements should add up to 180°. Note that m∠5 = 40°, and m∠2 = 140° (Given). Set the equation
m∠5 + m∠2 = 180
Plug in the number for each angle
40 + 140 = 180
180 = 180 (True).
e. It is proven that the above measurements are congruent with their corresponding parts. This means that a || b through Converse of Same Side Interior angle Theorem.

travis has three moths to save money for a trip. an airplane ticket costs more than 300 . if he saves the same amount of money ,a,each month,how much does he need to save each month to pay for the ticket
Answer:
He needs to save $100 a month.
Step-by-step explanation:
Since Travis needs $300 in 3 months, you divide 300 by 3.
300/3 = 100
Therefore, Travis needs to save $100 a month.
Travis needs to save more than $100 each month for three months to afford an airplane ticket that costs more than $300.
Explanation:To determine how much Travis needs to save each month to pay for his airplane ticket, which costs more than $300, we can set up an equation. Let's assume the minimum amount he needs for the ticket is $300. If Travis is saving for three months, he needs to divide the total cost of the ticket by the number of months he has to save.
Let the amount he needs to save each month be represented by a. Therefore, we have the following equation: 3a = 300, which simplifies to a = 300/3. Solving this, we find that a = $100.
However, since the ticket costs more than $300, he will need to save slightly more than $100 each month.

the permitir of the garden is (6x+2) units. Find the length of the missing side .
Answer: ? = x + 1
Step-by-step explanation:
The perimeter of the garden is x + 3x + 1 + x + ?
The perimeter of the garden is also (6x + 2)
Therfore:
x + 3x + 1 + x + ? = 6x + 2
Collect like terms:
5x + 1 + ? = 6x + 2
Subtract 5x from both sides:
1 + ? = x + 2
Subtract 1 from both sides:
? = x + 1
You cannot find ? as a number, only in terms of x.
A 10 meter long ladder rests against a vertical wall so that the distance between the foot of the ladder and the wall is 2 meter. Find the angle the ladder makes with the wall and height above the ground at which the upper end of the ladder touches the wall. Round your answer to the nearest hundredth of a degree if necessary.
Answer:
1. The angle ladder makes with the wall is 11.54°
2. The height above the ground at which the upper end of the ladder touches the wall is 9.80 m
Step-by-step explanation:
∠A is what we are trying to find. Also AC is the length we are trying to find, as well.We see that the side opposite of ∠A and the hypotenuse (side opposite of 90 degree angle) of the triangle are known. The ratio that relates these two sides are SINE.
We know,
[tex]sin(angle)=\frac{opposite}{hypotenuse}[/tex]
Thus we can write:
[tex]sin(A)=\frac{2}{10}\\sin(A)=\frac{1}{5}[/tex]
To find ∠A, we take the inverse sine of [tex]\frac{1}{5}[/tex]. Our answer is:
[tex]sin(A)=\frac{1}{5}\\A=sin^{-1}(\frac{1}{5})\\A=11.54[/tex]
Thus the angle ladder makes with the wall is 11.54°
Second part of the question asks for the height above the ground at which the upper end of the ladder touches the wall, this is the length of AC.
Given the angle we found, we see that the side AC is adjacent of the angle and we also know the hypotenuse. The ratio that relates these 2 sides is COSINE.
We know,
[tex]cos(angle)=\frac{adjacent}{hypotenuse}[/tex]
Thus, we can write:
[tex]cos(11.54)=\frac{AC}{10}[/tex]
Cross multiplying and solving for AC, gives us:
[tex]cos(11.54)=\frac{AC}{10}\\AC=10*cos(11.54)\\A=9.80[/tex]
Thus, the height above the ground at which the upper end of the ladder touches the wall is 9.80 m
