95/100 = 0.95 <== if she missed 5 out of 95, then she got 95 out of 100
Answer:
{x,y}={-8,-2}
Step-by-step explanation:
[1] x = 2y - 4
Plug this in for variable x in equation [2]
[2] 7•(2y-4) + 5y = -66
[2] 19y = -38
Solve equation [2] for the variable y
[2] 19y = - 38
[2] y = - 2
By now we know this much :
x = 2y-4
y = -2
Use the y value to solve for x
x = 2(-2)-4 = -8

Answer:
Step-by-step explanation:
58+q=180 (opposite angles of a cyclic quadrilateral are supplementary)
q=180-58=122°
similarly p+90=180
p=180-90=90°
To find this answer you would use the formula for finding the volume of a cylinder. Because both of these cylinders are congruent, the area of the base for cylinder A I would also be the same area for cylinder B. V=pi x r^2 x h. When we substitute in what we know this is the new equation: 27 x pi = pi x r^2 x 3. Divide both sides by three and pi. This gives us 9 = r^2. Take the square roots of both sides to find the radius. The answer would be 3. Now use the formula for area of a circle to find the area of the base of cylinder B. A= pi x r^2. So the area would be 9 x pi.
