bekas [8.4K]
The answer is -60. this is because the signs implemented in front of numbers give it a sort pattern .

when there are two additions the last number after the positive sign will give a positive number 1 greater than the initial number for example + 5 + 6. Answer afterward will be + 7 and for negative sign eg: - 7 - 8 in the question will give the answer -8 the same number after a negative (-) sign .
Hope this helps

A lab technician made a 14 cm diameter hole through the middle of a cylinder that has a diameter of 20 cm and a height of 28 cm.
Step2247 [10]

Answer:

The volume of the finished cylinder is 4486.2 m^3

Step-by-step explanation:

To find the volume of the finished cylinder, we have to first find the volume of the hole (with 14 cm diameter and a height of 28 cm) and subtract it from the volume of the original cylinder (with diameter of 20 cm and a height of 28 cm).

Note: The hole is also cylindrical in shape.

The volume of a cylinder is given as:

V = \pi r^2h

where r = radius, h = height

VOLUME OF THE HOLE

The diameter of the hole is 14 cm, hence, its radius is 7 cm (14 / 2 = 7)

Its volume is:

V = \pi *7^2 * 28\\V = 4310.3 m^3

VOLUME OF THE ORIGINAL CYLINDER

The diameter of the cylinder is 20 cm, hence, its radius is 10 cm (20 / 2 = 10)

Its volume is:

V = \pi *10^2 * 28\\V = 8796.5 m^3

Hence, the volume of the finished cylinder will be:

8796.5 - 4310.3 = 4486.2 m^3

The volume of the finished cylinder is 4486.2 m^3

Joaquin has a grade of 81 and 70 on her first two algebra test if she wants an average of 73 what possible score can she get on
Anvisha [2.4K]
81 + 70 + x = 3(73)
first multiply 3(73)

81 + 70 + x = 219
combine like terms

151 + x = 219
subtract 151 from both sides

x = 68

Joaquin needs to score a 68 on her next test to maintain an average of 73.
