mihalych1998 [28]

Answer:

C.14¾

3 9⁄10

Step-by-step explanation:

$\frac{4}{5} + 3 \frac{1}{10} = \frac{8}{10} + 3 \frac{1}{10} = 3 \frac{9}{10}$

$4 \frac{7}{12} + 2 + \frac{3}{4} + 7 \frac{5}{12} = 13 \frac{12}{12} + \frac{3}{4} = 14 + \frac{3}{4} = 14 \frac{3}{4}$

A car's wheels spins at 1000 revolutions per minute. The diameter of the wheels is 23 inches. You want to know how fast the car

ch4aika [34]

Answer:

72,220 inches per minute

Step-by-step explanation:

A car's wheels spins at 1000 revolutions per minute. The diameter of the wheels is 23 inches.

1 revolution = $2\pi$ radians

$\frac{theta}{tome}=\frac{1000 \ revolution}{1 \ minuite} = \frac{1000* 2\pi }{1} =\frac{2000\pi}{1 \ minute}$

Speed $V= \frac{r*theta}{t}$

r is the radius , theta is the angle and t is the time

We know diameter = 23 , then radius = 23/2

Speed $V= \frac{23}{2}*\frac{2000\pi}{1}$

Value of pi = 3.14

speed = 23000* 3.14= 72220 inches/ minute

Ty received test grades of 82%, 74%, 76%, 76%, and 74%.

Nikitich [7]

Answer:

a) To earn C he needs at least 68 and less than 98

b) No, he couldn't make it.

Step-by-step explanation:

I. His avg value is (382 + x)/6

I pick a random number and that gave

(68 => to reach 75) and (98 => to reach 80)

So that makes he needs at least 68 and less than 98

II. The reason why he cannot make it is

if 100 is 100%

= (100 + 382)/6

= 80.33 That's impossible to reach 90

Hope that help :)
