Answer:
A)$2.50 x b = total cost
B) 9 x 2.50 = $22.5
C) 50 x $2.50 = $125 - $14.75 = $110.25
5 | 8 |12
40|35 |103
29|68 |148
65|172|324
(9x + 5) - (4x+3) = 0
9x - 4x + 5 - 3 = 0
5x + 2 = 0
5x = -2
5x/5 = -2/5
x= -2/5
Answer:
S = R θ where θ is in radians
If θ = 2 pi then S = 2 pi R the circumference of the circle
θ = S / R = 9.7 / 9 = 1.08 rad
Since 1 rad = 360 / (2 pi) = 57.3 deg
the angle included = 1.08 rad * 57.3 deg/rad = 61.9 deg
Answer:
813.4 cm² (nearest tenth)
Step-by-step explanation:
<u>Volume of a cylinder</u>

Given:
Use the Volume of a Cylinder formula and the given values to find the <u>radius of the cylinder</u>:



<u>Surface Area of a Cylinder</u>

Substitute the given value of h and the found value of r into the formula and solve for SA:




Therefore, the surface area of the cylinder is 813.4 cm² (nearest tenth)
