The ladder should be placed three feet away from the wall
To get the surface area of a sphere, we need to have the radius. We are given the circumference. The circumference formula is C=2πr. We need to solve for r.
23 = 2πr
r=3.66
The calculation for surface area is <span>A = 4πr^2.
</span>A = 4<span>π(3.66)^2
Solve for A.
A= 168 cm^2.</span>
The answer would be
X=-2y
Move all the terms that don't contain x to the right side and solve.
The new line intercepts the y axis at point (0, 1), so that is the end of the equation, and I believe the slope of the line is 1 because each corner of each square on the grid is connected. This gives you the equation of y = 1x + 1, or y = x + 1. I hope this helps!
Answer:
18.75
Step-by-step explanation:
Remark
For this question, you need to set up a proportion. The ratio on each side of the equal sign is dollars over pounds.
Proportion
15/8 = x / 10 Cross Multiply
Solution
8x = 15 * 10 Combine
8x = 150 Divide by 8
x = 150/8
x = 18.75
