in a circle graph, what is the measure of the central angle of a sector that represents 24% of the whole?

Answers

Answer 1

Answer: 0.24*360=86.4 degrees

Answer 2

Answer: 24/100 =x/360

100x=8640
x=86.4

B. -2

Step-by-step explanation:

let the number be x

=7+x

=3(7+x)

=3(7+x)-2

13=3(7+x)-2

solving for x we have

13=21+3x-2

21+3x-2-13=0

collect like terms we have

21-2-13+3x=0

6+3x=0

6=-3x

x=6/-3

x=-2

The answer is B

B. -2

The current cost of a box of cereal is $3.39. At the time of this writing, the CPI for cereal is 289.7. What was the cost of a box of cereal in 1983 to the nearest cent?

Answers

To solve this problem we have to first identify the data that we need and is important. You can arrange it like this:

Current Cost of Cereal: $3.39

CPI: 289.7

To find the cost of a box of cereal in 1983 we will need to use the following formula:

Cost in Base Year = Current Cost/CPI*100

Replace the data in the formula and we get the following:

1983 = 3.39/289.7*100

In 1983 the cost of a box of cereal was $1.170176044

I hope this helps, Regards.

A storage company has a rectangular storage area 20m long, 8m wide and 2.8m wide. How many boxes of dimensions 1m x 0.5m x 2.5m can fit into this storage area?

Answers

For this question I think you can find the volume of the storage room and then divide that by the volume of the boxes going into the storage room to see how many boxes can fit into it.
448 cubic meters in the storage area divided by 1.25 cubic meters per box equals 358.4 boxes.

you might need to put 358 since it would be weird to only have .4 of a box.

Ted needs an average of at least 70 on his three history test he has scored already 85 and 60 on two test what is the minimum grade ted need on his third test?

Answers

so average=(total of scores)/(number of tests)
needs at least average of 70
at least is represented as greater than or equal to or the sign (>)
70>(total)/(number oftests)

since we have 3 tests, we have to have 3 scores so
70>(x+y+z)/3
he scored 85 and 60
70>(x+85+60)/3 (doesn't matter which to subsitute)
70>(x+145)/3
multiply obht sides by 3
210>x+145
subtract 145 from both sides
65>x
he needs to get at leas 65 on his third test

You lean a 30 foot ladder against your house and it reaches exactly to the top. The ladder makes a 24 degree angle with the ground. How tall is your house?

Answers

A right triangle is formed with the ladder as the hypotenuse. Since the angle made by the ladder with with ground is given, we can use trigonometric functions to solve for the height of the house.

If we let x be the height of the house and using sine function:
sin 24 = x/30
x = 30 sin 24
x = 12.20 ft

Therefore, the house is 12.20 ft tall
