Kelly combines 6.54 ounces of strawberries with 6.09 ounces of blueberries to make fruit bowls.She pours the fruit equally into three bowls, and has 1.68 ounces of fruit left over. How many ounces of fruit are in each bowl?
Answers
Answer:
3.65 ounces in each bowl
Step-by-step explanation:
Strawberry=6.54 ounces
Blueberry=6.09 ounces
If Kelly combines the two fruits to make fruits bowls
Then,
6.54 ounces of strawberry + 6.09 ounces of blueberry=12.63 ounces of fruits.
She pours the fruits equally in each bowl and has a leftover of 1.68 ounces.
Let quantity in each bowl = x
There are 3 bowls
Total quantity in three bowls=3x
Leftover=1.68
Total fruits = 12.63
We have the equation
3x+1.68=12.63
Subtract 1.68 from both sides
3x=12.63-1.68
3x= 10.95
Divide both sides by 3
x=10.95/3
x=3.65
Answer:
3.65 ounces of fruit in each bowl
Step-by-step explanation:
If the combination was made with 6.54 ounces of strawberries and 6.09 ounces of blueberries, the total ounces of fruit used is 6.54 + 6.09 = 12.63 ounces.
The remaining after dividing in three bowls is 1.68, so the amount used is 12.63 - 1.68 = 10.95 ounces
If we divide this amount of fruit by three bowls, we have:
Amount of fruit per bowl = 10.95 / 3 = 3.65 ounces

(1). Every 12 games Alice wins 8 games and looses 4. ( 8/12 )
(2). Alice wins 2/3 games against a computer. ( 8/12 )
(3). Alice wins 66% of games she plays against a computer.
There you go.
Alice's win ratio for playing checkers against a computer is 8 wins out of 12 games, which simplifies to 2/3.
Alice has played 12 checker games against a computer and has won 8 of them. To understand her win ratio, we simply divide the number of games won by the total number of games played. This gives us a ratio or fraction of 8/12, which can also be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 4, resulting in 2/3. Therefore, Alice has a winning ratio of 2 wins for every 3 games played. Understanding win ratios is an essential part of probability and statistics, a key area within mathematics dealing with the analysis of numerical data.

The volume of a sphere is 4,186.67 cm cubed. To the nearest centimeter, what is the radius of the sphere? Use 3.14 for π.
A.8
B.5
C.10
Answers
Cube root 111 is about 5
B. 5
Using the volume formula for a sphere (V = (4/3)πr3), the radius for the given volume of 4,186.67 cm3 is calculated to be 10 cm, making option C correct.
Explanation:The volume of a sphere is given by the formula V = (4/3)πr3. To find the radius of a sphere with a volume of 4,186.67 cm3, we rearrange the formula to solve for r:
r = ∛((3V) / (4π))
Substituting the given volume and 3.14 for π:
r = ∛[(3×4,186.67 cm3) / (4×3.14)]
r = ∛[(12,560.01 cm3) / (12.56)]
r = ∛(1,000)
r = 10 cm
So, to the nearest centimeter, the radius of the sphere is 10 centimeters, making option C the correct answer.

How much money should be deposited today in an account that earns 6% compounded semiannually so that it will accumulate to $14,000 in three years?
Answers
Answer:
The amount of money to be deposited today is $11,725
Step-by-step explanation:
In this question , we are concerned with calculating the amount of money that should be deposited presently to have $14,000 in three years.
To get this, we have to use the compound interest formula
A = P( 1+ r/n)^nt
where A is the amount to be earned after the end of the compounding period which is $14,000 according to this question
P is the initial amount to be deposited which is what we are looking for
r is the rate of compounding which is 6% or simply 6/100 = 0.06
n is the number of times interest is compounded yearly which is semiannually according to the question and this means 2
t is the number of years which is 3 according to the question
Now, plugging all these values, we have;
14,000 = P( 1 + 0.06/2)^(3 * 2)
14,000 = P(1+0.03)^6
14,000 = P(1.03)^6
14,000 = 1.194P
P = 14,000/1.194
P = 11,724.77 which is approximately $11,725

if y varies directly as x and y = 34 when x = 8, determine an equation to represent this relation.
Answers
Answer:
y = 4.25x
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 34 when x = 8, thus
34 = 8k ( divide both sides by 8 )
k = [tex]\frac{34}{8}[/tex] = 4.25
y = 4.25x ← equation of variation
The center of a circle is located at (3, -4). The radius of the circle is 6.
What is the equation of the circle in general form?
x2 + y2 + 6x − 8y − 11 = 0
x2 + y2 − 6x + 8y − 11 = 0
x2 + y2 + 6x − 8y + 19 = 0
Answers
Answer:
B
Step-by-step explanation:
The equation of a circle in standard form is [tex](x-h)^2+(y-k)^2=r^2[/tex], where (h, k) is the center and r is the radius. The general form is simply the expanded form of the standard. Let's first write the standard form.
Here, the center is (3, -4) and the radius is r = 6, so:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
[tex](x-3)^2+(y+4)^2=6^2[/tex]
Now expand:
x² - 6x + 9 + y² + 8y + 16 = 36
x² + y² - 6x + 8y - 11 = 0
The answer is B.
Answer:
x² + y² - 6x + 8y - 11 = 0
Step-by-step explanation:
Equation of a circle:
(x - h)² + (y - k)² = r²
(x - 3)² + (y + 4)² = 6²
x² - 6x + 9 + y² + 8y + 16 = 36
x² + y² - 6x + 8y - 11 = 0

Answer:
If you meant to type f(x) = (4 - 2x)^2 - 4, then choose choice B.) domain: all real numbers
range: all real numbers greater than or equal to –4
----
With your typo... the choices narrow down to choice B and A. . The domain is definitely all real numbers for a quadratic function.
Step-by-step explanation:
We have a quadratic function
f(x) =4 -2*x^2 - 4
I assume there is a typo here.
check y >= -5 and y >= -4...
what if f(x) = (4 - 2x)^2 - 4
then f(x) = 4*(x - 2)^2 - 4 with vertex at (2, -4) which makes sense with the answer choice B.)
f(x) = 4*(xx - 4x + 4) - 4 = 4xx - 16x + 16 -4 = 4xx - 16x +12 ...
The domain of the function is all real numbers, and the range is all real numbers greater than or equal to -4.
The correct answer is option B.
Certainly, let's discuss the domain and range of the function f(x) = 4 - 2x^2 - 4 :
Domain (Possible x-values):
The domain of a function represents all the possible input values (x-values) for which the function is defined. In this case, f(x) is a polynomial function, and polynomial functions are defined for all real numbers. Therefore, the domain is all real numbers. So, options (A) and (B) are incorrect because they limit the domain.
Range (Possible y-values):
To determine the range, we need to analyze how the function behaves. The function f(x) = 4 - 2x^2 - 4 is a quadratic function with a leading coefficient of -2. It opens downward, and its vertex is at the point (0, 0). As x moves away from the vertex in either direction, the function value decreases without bound. Therefore, the range is all real numbers less than or equal to -4 because the function never goes above -4. So, options (C) and (D) are incorrect because they indicate that the range includes positive values.
Based on the analysis, the correct answer is:
B.) domain: all real numbers
range: all real numbers greater than or equal to -4

Step-by-step explanation:
2/(2/3)=3
Answer: 3 times.
Step-by-step explanation:
To find how many times 2/3 goes into 2, convert 2 to a fraction with the same denominator as 2/3.
You can do this by multiplying the fraction 2/1 by 3/3 to make the denominator equal 3:
[tex]\frac{2}{1}*\frac{3}{3} =\frac{6}{3}[/tex]
Then, you can divide the fractions. Because 6/3 and 2/3 have the same denominator, you can simply divide 6 by 2.
2/3 goes into 2 three times.

Answers
Answer:
Option (1). 6 inches
Step-by-step explanation:
Given question is incomplete; here is the complete question.
Tony needs 16-inch pieces of gold chain to make each of 3 necklaces. He has a piece of chain that is 4 1/2 feet long. How much chain will he have left after making the necklaces ?
Tony has a piece of chain = 4.5 feet long
≈ 4.5 × 12 inches
≈ 54 inches
Number of necklaces Tony wants to make = 3
Length of every piece of gold chain required for one necklace = 16 inches
Total length of gold chain required for 3 necklaces = 3 × 16 inches
= 48 inches
Length of remaining chain = 54 - 48 = 6 inches

In a race in which eleven automobiles are entered and there are no ties, in how many ways can the first three finishers come in?
Answers
Answer:
990 ways
Step-by-step explanation:
The total number of automobiles we have is 11.
Now, what this means is that for the first position , we shall be selecting 1 out of 11 automobiles, this can be done in 11 ways( 11C1 = 11!/(11-1)!1! = 11!/10!1! = 11 ways)
For the second position, since we have the first position already, the number of ways we can select the second position is selecting 1 out of available 10 and that can be done in 10 ways(10C1 ways = 10!9!1! = 10 ways)
For the third position, we have 9 automobiles and we want to select 1, this can be done in 9 ways(9C1 ways = 9!/8!1! = 9 ways)
Thus, the total number of ways the first three finishers come in = 11 * 10 * 9 = 990 ways

A full water tank holds 500 litres.
The tank begins to leak water and is losing 14% of its contents every hour. Find how much water is left in the tank after 8 hours.
Answers
Answer:
0 Litres
Step-by-step explanation:
If the tank holds 500 litres and its loosing 14% every hour, just multiply
14%x8h=112%
This means the tank has lost all of its water.
You can also do 500/100=5 <- 1% of the tank, then multiply it by 14 and it gives you 70 litres. Then, multiply this by 8 and its gonna be 560 litres. So this means the tanks is going to have 0 litres left at the end.
The quantity of water present in the tank after 8 hours will be 123.94 liters.
