Answer:
z = 5
Step-by-step explanation:
[tex]\frac{4x^2y^7}{8x^3y^2} = \frac{y^z}{2x}[/tex]
It can be also written as -
[tex]\frac{2^2 \times x^2 \times y^7}{2^3 \times x^3 \times y^2} = \frac{1 \times x^0 \times y^z}{2 \times x^1 \times y^0}[/tex]
Using law of exponents , lets solve this.
[tex]=> 2^{(2-3)} \times x^{(2-3)} \times y^{(7 - 2)} = \frac{1}{2} \times x^{(0-1)} \times y^{(z-0)}[/tex]
[tex]=> 2^{-1} \times x^{-1} \times y^{5} = 2^{-1} \times x^{-1} \times y^z[/tex]
[tex]=> \frac{y^5}{2x} = \frac{y^z}{2x}[/tex]
[tex]=> y^z = y^5[/tex]

If 3x-7=5x, what is 6x?
Answer:
6x = - 21
Step-by-step explanation:
Given
3x - 7 = 5x ( subtract 3x from both sides )
- 7 = 2x
Then
6x = 3 × 2x = 3 × - 7 = - 21

12 in
12 in
What is the area, in square inches, of the smallest circular piece of lace Jackson could buy? Round your answer to the nearest tenth
Answer:
226.2
Step-by-step explanation:
I took the test. I hope this helps! :)
The area of the circular lace is required.
The smallest circular piece of lace to cover the entire top of the table is 226.2 inches².
Area of circleLength of each side of square = 12 inches
The diameter of the circle will be the length of the diagonal of the square from the given figure.
[tex]d=\sqrt{12^2+12^2}\\\Rightarrow d=12\sqrt{2}\ \text{in}[/tex]
Area of a circle is given by
[tex]A=\pi\dfrac{d^2}{4}\\\Rightarrow A=\pi \dfrac{(12\sqrt{2})^2}{4}\\\Rightarrow A=226.194\approx 226.2\ \text{in}^2[/tex]

A group of seven people went to an amusement park and spent $234 on tickets. If
a child's ticket costs $28 each and an adult ticket costs $37.50 each, how many
adult tickets and how many child tickets were purchased?
Answer:
3 adult tickets and 4 child tickets were bought.
Answer:
4 adult tickets and 3 child tickets
Step-by-step explanation:
So doing 234/7 gives you 33.428... which means its not all just children or adults. (I know that's common sense but it's best to do this anyway to further justify your answer)
The total cost for all 7 people shows that there must be an even amount of adult tickets to end up with a whole number so either 2, 4, or 6 adults.
2 adults = $75
4 adults = $150
6 adults = $225
Now we can use these possibilities to figure out if the left over child tickets added to the adult tickets would equal $234. (quick note: I am using # to show that it doesn't equal $234)
If 2 adults = $75, 5 children = $140, $140+$75 = $215 # $234
If 4 adults = £150, 3 children = $84, $84+$150 = $234
Now because we have already figured out that it would be 4 adult tickets and 3 child tickets, we wouldn't need to figure out 6 adult tickets and 1 child ticket, but, again, this would justify your answer and help to secure your marks.
If 6 adults = $225, 1 child = 28, $28+$225 = $253 # $234
I hope this answer helped you out and if you have any questions I'd be happy to help :)
An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms. 3/4 of this weight is metal, and the rest is wood. How much does the wood part of the sculpture weigh? (no decimals)
Answer:Weight of wood part of the sculpture (no decimals) =4kg
Step-by-step explanation:
Weight of sculpture containing metal and wood = 14.9 kg
weight of metal =3/4 x 14.9 kg =11.175kg
weight of wood =Entire sculpture − weight of metal
= 14.9 kg−11.175kg
=3.725kg
Rounding up to remove decimals we have that Weight of wood part =4kg

The acceleration of an object varies directly as the force acting on it. If a force of 240 Newtons causes an acceleration of 150 m/s squared, what force will cause an acceleration of 100 m/s squared?
Answer:
The acceleration of an object varies directly as the force acting on it. If a force of 240 newtons causes an acceleration of 150 m/s², what force will cause an acceleration of 100 m/s?? 2. The stretch in a loaded spring varies directly as the load it supports.
Answer:
160 Newtons
Step-by-step explanation:
240÷150= 1.6. 100x1.6 gives us the answer which is 160 Newtons for 100m/s. For every 1.6 newtons,1 m/s is gained.
