Answer:
12
+ 6y
Step-by-step explanation:
Best to look up the formula for the surface area of a sphere and then find it:
A = 4πr^2, where r is the radius of the sphere. Then,
A = 4π(15 in)^2 = 4(3.14)(225 in^2) = 2826 in^2 (answer)
This is represented by the formula given in the lower left.
Answer:
x = 31
Step-by-step explanation:
The 88-deg angle is an exterior angle of the triangle.
The 57-deg angle and x are its remote interior angles.
<em>Theorem:</em>
<em>The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.</em>
x + 57 = 88
x = 31
Answer:
- x = 3
- y = 4.
- There are infinite solutions. I'll just give you this solution.
Step-by-step explanation:
<u>Given equation:</u>
<u>Solve for variables:</u>
- 7 - x = y
- 7 - 3 = 4
- 7 - y = x
- 7 - 4 = 3.
<u>Answers:</u>
Let p = her pay per week.
<span>"Karissa earns $200 per week plus $25 per item she sells."
She earns a fixed amount of $200 per week no matter how much she sells.
Then she earns an additional variable amount that depends on the number of items she sells. It is $25 per item.
p = fixed amount + variable amount
The variable amount is:
If she sells 1 item, she earns 25 * 1
If she sells 2 items, she earns 25 * 2
If she sells 3 items, she earns 25 * 3
If she sells n items, she earns 25 * n
The variable amount she earns is 25n, where n is the number of items she sells.
</span>
<span>p = fixed amount + variable amount
p = 200 + 25n
</span>
