A pecan pie is being served for dessert. One piece of pie has an arc length of 7.85 in. It has been cut into 8 equal pieces. Wha
grin007 [14]

Answer:

The radius of the pie is 6.17 in.

Step-by-step explanation:

The formula for arc length as a function of radius is

s = r·Ф, where Ф is the central angle in radians.

Here we know that the arc length is 7.85 in.  Assuming that the whole pie has been cut into 8 equal pieces, the central angle of one such piece is

2π / 8, or π /4 (radians).

thus, s = r·Ф, solved for r, is r = s/Ф

and in this instance r = (7.85 in)/(π/4).  Evaluating this, we get:

                                 r = 6.17 in

The radius of the pie is 6.17 in.

If EF - 3x - 11, FG = 4x-10, and EG - 28, find the values of x, EF, and FG. The drawing is not to scale.
Gnom [1K]

Answer:

Part 1) x=7

Part 2) EF=10\ units

Part 3) FG=18\ units

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the value of x

we know that

EG=EF+FG ---> by addition segment postulate

we have

EG=28\ units\\EF=3x-11\\FG=4x-10

substitute

28=(3x-11)+(4x-10)

solve for x

28=7x-21

7x=28+21

7x=491

x=7

step 2

Find the value of EF

EF=(3x-11)

substitute the value of x

EF=3(7)-11=10\ units

step 3

Find the value of FG

FG=(4x-10)

substitute the value of x

FG=4(7)-10=18\ units

A computer uses 1/200 second of a secount to finish a math problem . How many math questions can the computer solve in 2 minutes
aniked [119]

Answer: The computer can solve 24,000 math problems in 2 minutes.

Step-by-step explanation:

1.) Multiply 1 * 200, in order to get the amount of problems solved in a second, which would be 200.

2.) Multiply 200 * 60 to get the amount of problems solved in a minute, which would be 12,000.

3.) Multiply 12,000 * 2 in order to get the amount of problems solved in 2 minutes, which would be 24,000.
