Answer:
it would take Edward 8 to pay back his debt
Step-by-step explanation:
every 2 days he pays his parents 5 bucks so because 5 times 4 equals 20 he would have to multiply the 4 by 2 and that gets you 8 days
Final answer:
Edward will pay back his $20 debt to his parents by repaying $5 every 2 days; thus, it will take him 8 days in total to repay the full amount.
Explanation:
The question asks us to determine how long it will take for Edward to pay back a $20 debt to his parents if he repays $5 every 2 days. To solve this, we can set up a simple table showing the cumulative amount paid over time, and then establish a corresponding graph if needed. Here's how the repayment schedule works out:
Day 0: $0 paid back
Day 2: $5 paid back (Total: $5)
Day 4: $5 paid back (Total: $10)
Day 6: $5 paid back (Total: $15)
Day 8: $5 paid back (Total: $20)
From the table, it is clear that it will take Edward 8 days to pay back the full $20 debt.

The volume of a container varies jointly with the square of its radius, r, and its height, h. The
container has a height of 10 centimeters, and radius of 6 centimeters, and a volume of 377 cubic
centimeters. What is the volume of a container with a radius of 4 centimeters and a height of 4
centimeters?
Your answer
Solution:
The volume of a container varies jointly with the square of its radius, r, and its height, h
Therefore,
[tex]v \propto r^2 h\\\\v = k \times r^2h -------- eqn\ 1[/tex]
The container has a height of 10 centimeters, and radius of 6 centimeters, and a volume of 377 cubic centimeters
Substitute v = 377 and h = 10 and r = 6 in eqn 1
[tex]377 = k \times 6^2 \times 10\\\\377 = k \times 360\\\\k = 1.047 \approx 1.05[/tex]
What is the volume of a container with a radius of 4 centimeters and a height of 4 centimeters?
Substitute k = 1.05 and r = 4 and h = 4 in eqn 1
[tex]v = 1.05 \times 4^2 \times 4\\\\v = 1.05 \times 16 \times 4\\\\v = 67.2[/tex]
Thus volume of a container with a radius of 4 centimeters and a height of 4 centimeters is 67.2 cubic centimeter

A bag contains 9 red marbles,5 green marbles, and 6 purple marbles.
What are the odds of picking a red marble?
The odds or probability of picking a red marble from a bag that contains 9 red marbles, 5 green marbles, and 6 purple marbles is 0.45 or 45%.
Probability refers to the chance, likelihood, or odds that an event occurs out of many possible events.
Probability is a value that ranges from 0 to 1, depending on the level of certainty.
The number of red marbles in the bag = 9
The number of green marbles in the bag = 5
The number of purple marbles in the bag = 6
The total number of marbles in the bag = 20 (9 + 5 + 6)
The probability of choosing or picking a red marble = 9/20 = 0.45 or 45%.

Mode: 33 Mean: 35.5
Step-by-step explanation:
The mode of a data set is the number that appears most often.
So the mode of this set would be 33, since it appears twice.
The mean of a data set is the average of the numbers.
To find the mean (average), add all eight numbers together, then divide by eight...
31 + 29 + 33 + 37 + 43 + 38 + 33 + 40 = 284
284 / 8 = 35.5
So, the mean of the numbers is 35.5!

Brisa's kite is flying above a soccer field at the end of 43 m of string. If the angle of elevation to the kite measures 72degree, and Brisa is holding the kite 1.2 m off the ground. How high above the ground is the kite flying? (Round to the nearest meter)
Answer:
The height the kite is flying above the ground level to the nearest meter is 42m.
Step-by-step explanation:
this is not drown to scale:
|\
| \
x | \ 43m
| \
|___\
Angle is 72º
sine = opposite / hypotenuse
sin 72 = x / 43
0.9510565 = x / 43
therefore x = 40.9m
Brisa is holding the kite 1.2 m off the ground, we also need to add 1.2 m to our calculated height of the kite. Thus, the answer is
40.9 m + 1.2 m = 42.1 m to the nearest meter is 42m.
Carson went to pick apples at an orchard.he gave one-third of his apples to his friend Nathan.then he gave one-half of what he had to his friend Nikki.on his way home he dropped one-fourth if what he had left,so that he only had 9 for him and his family.how many apples did Carson pick originally?
Answer:
36 apples
Step-by-step explanation
Step 1 = he dropped 1/4 and was left with 9
Finding 1/3 one third of 9 = 3.
Then 9 +3 = 12
Step 2 He parted with 1/2 and was left with 12
12x2=24
Step 3 He parted with 1/3 and was left with 24
= 12+ 12 + 12 = 36 Where 1/3 of 36 = 24
Answer = 36
Answer:
36
Step-by-step explanation:
Carson had x number of apples to start with.
He gave 1/3 to Nathan. Now Carson has (2/3)x apples left.
He gave 1/2 of what was left to Nikki. Now Carson has (1/2)(2/3)x = (2/6)x = (1/3)x apples.
On the way home, he dropped 1/4, so he has 3/4 of the last amount he had, and the number is 9.
(3/4) * (1/3)x = 9
3/12 x = 9
1/4 x = 9
x = 36
Answer: He picked 36 apples.
Check:
Start with 36 apples.
Give 1/3 to Nathan. Now Carson has 24 apples.
Give 1/2 to Nikki. Now Carson has 12 apples.
Drop 1/4. 1/4 of 12 is 3. 12 - 3 = 9.
Hew only had 9 apples left, so 36 is correct.
Does the point (273, 2) lie on the circle that is centered at the origin and contains the point (0, -4)? Explain?
Answer:
No, the point (273, 2) does not lie on the circle that is centered at the origin and contains the point (0, -4)
Step-by-step explanation:
The circle centered at the origin that contains the point (0,-4) has equation:
[tex] {x}^{2} + {y}^{2} = 16[/tex]
If the point (273,2) lies on this circle , then it must satisfy this equation:
[tex] {273}^{2} + {2}^{2} = 74533[/tex]
Since
[tex]16 \ne74533[/tex]
The point does not lie on this circle.

Eduardo earns a base salary of $30,000 per year and earns $1,875 per car he sells. Which equation can be used to find the number of cars, c, that Eduardo sold in a year he made 46,875 ?
Answer:
The equation is, A =30,000 + 1875n.
He sold 9 cars the year he made that amount of money.
Step-by-step explanation:
Before calculating, let's assign letters to certain variables:-
✓ let "A" be used to represent the total amount earned after adding his base salary to the amount he earned as commission per car he sells.
✓ "P" will be used to represent his base salary (a constant = 30,000)
✓ "n" will represent the number of cars sold within a given year.
✓ "B" will be used to represent his commission per car he sells.
Fixing them into a formula, we have:
A = P + n(B)
Since "P" and "B" are constants of 30000 and 1875 respectively, we substitute the letters for their actual amount in the formula:-
A = 30,000 + n(1875)
A = 30,000 + 1875n +This is now the equation that can be used to calculate the number of cars he sold in the year he earned 46,875).
So, since "A" is now $46,875, we substitute accordingly to find the number of cars he sold in the year he earned such amount.
46,875 = 30,000 + 1875b
1875n = 46,875 - 30,000
1875n = 16875
n = 16875/1875
n = 9 cars
Therefore the equation to be used to determine how many cars he sold when he earned $46,875 is:
A = 30,000 + 1875n
He sold 9 cars the year he earned $46,875.

C.) f(x) - f(4) = (-5 + 3x) - (-5 + 3(4)) = -5 + 3x + 5 - 12 = 3x - 12
D.) f(x - 4) = -5 + 3(x - 4) = -5 + 3x - 12 = 3x - 17
E.) g(x + 1) = -2(x + 1)^2 + 5(x + 1) - 1 = -2(x^2 + 2x + 1) + 5x + 5 - 1 = -2x^2 - 4x - 2 + 5x + 4 = -2x^2 + x + 2

The area of the figure is A. 216 cm².
Step-by-step explanation:
Step 1:
To calculate the value of the composite shape we first divide it into shapes that we know.
In this case, the composite figure consists of a rectangle and a triangle attached to it.
If we can calculate the individual areas of the two shapes we should be able to calculate the area of the composite shape.
Step 2:
The triangle has a base length of 8 cm and a height of 12 cm. The area of the triangle [tex]=\frac{1}{2} (b)(h)=\frac{1}{2} (8)(12) = 48.[/tex]
The area of the triangle is 48 cm².
Step 3:
The area of a rectangle is the product of its length and its width.
The given rectangle has a length of 14 cm and a width of 12 cm.
The area of the rectangle [tex]= (l)(w) = (14)(12) = 168.[/tex]
The area of the rectangle is 168 cm².
Step 4:
Now we calculate the area of the entire figure by adding the areas of the triangle and the rectangle.
Area of the figure [tex]=48+168 = 216.[/tex]
So the area of the figure is 216 cm² which is option A.
