The volume of the solid is the amount of space in it.
The points on the graph are (0,0) and (1,7)
How to determine the points?The volume is given as:
V1 = 7
The scale factor is given as:
k
Let the new volume be V.
So, we have:
V = V1 * k^3
Substitute 7 for V1
V = 7k^3
Divide both sides by 7
k^3 = V/7
Take the cube root of both sides
k = (V/7)^1/3
Next, we test the options
a. (0,0)
k = (0/7)^1/3
k = 0 --- this is true
b. (1,1)
k = (1/7)^1/3
k = 0.05 --- this is false
c. (1,7)
k = (7/7)^1/3
k = 1 --- this is true
d (7, 1)
k = (1/7)^1/3
k = 0.05 --- this is false
e. (14,2)
k = (2/7)^1/3
k = 0.10 --- this is false
f. (49,2)
k = (2/7)^1/3
k = 0.10 --- this is false
g. (56,2)
k = (2/7)^1/3
k = 0.10 --- this is false
h (27,3)
k = (3/7)^1/3
k = 0.14 --- this is false
Hence, the points on the graph are (0,0) and (1,7)

Susan gave 1/6 of a pizza to her brother. She gave 1/3 of what was left to
her mother. Susan ate the rest herself. What fraction of the pizza did Susan
eat?
°1/2
°1/9
°1/18
°5/9
Answers
Answer:1/2
Step-by-step explanation: after giving some to her brother she has 5/6 left to take 1/3 from that you need to make it have a common denominator. to do that multiply it by 2 so you get 2/6. then do 5/6-2/6=3/6. 3/6 simplied is 1/2.

The critical value becomes 2.584 for two tailed test since we have to reject the null hypothesis, t >2.584 or t < -2.584 test stat lie in the rejection region.
Test-Static tData;
mean = 5.82s = 4.93n = 600Let's calculate the t-value
[tex]t = \frac{x - \mu}{\frac{s}{\sqrt{n} } }[/tex]
Substitute the values into the equation and solve;
[tex]t = \frac{x - \mu}{\frac{s}{\sqrt{n} } } \\t = \frac{5.82 - 5}{\frac{4.93}{\sqrt{600} }} \\t = \frac{0.82}{0.201} \\t = 4.079[/tex]
The t-value is 4.079
The allowed significance value = 0.01

Which expression represents y to the 4th power -36 in simplest factored form?
Answers
Answer:
(y^2 + 6)(y^2 - 6)
Step-by-step explanation:
First, substite variable x for y^2:
FOR x = y^2:
y^4 - 36
= (y^2)(y^2) - 36
= (x)(x) - 36
= x^2 - 36
Now, use the formula a^2 - b^2 = (a + b)(a - b):
x^2 - 36
= x^2 - 6^2
= (x + 6)(x - 6)
Finally, since the expression is factored for x, not y, substite y^2 in for x:
(x + 6)(x - 6)
= (y^2 + 6)(y^2 - 6)
[tex]= (y^2 + 6)(y^2 - 6)[/tex]

Which statement describes the difference in the distance
travelled by the two cars when 15 gallons of gasoline is used?
Both cars will have travelled the same distance.
Answers
Answer:
D. A travels 90 miles more
Step-by-step explanation:
The graph tells you Car A travels 140 miles on 5 gallons of gas. (There is a point marked there on the graph.)
The table tells you Car B travels 99 miles on 4.5 gallons of gas. When that is multiplied by 5/4.5 = 10/9 to get the equivalent for 5 gallons, we see that Car B could travel 10/9 × 99 = 110 miles on 5 gallons of gas.
__
Already on 5 gallons of gas, Car A has traveled 30 miles farther. The only sensible answer choice is ...
D. Car A travelled 90 miles more than Car B [when 15 gallons are used].

Step-by-step explanation:
See the drawing below.
This is a right triangle.
The legs have lengths 5 and 7.
We can find the length of the hypotenuse using the Pythagorean Theorem.
5² + 7² = e²
e² = 74
e = √74
perimeter = 5 + 7 + √74
perimeter = 12 + √74
area = bh/2
area = 5 × 7/2
