The missing figure is attached down

The length around the outside of the track is about 431 feet

Step-by-step explanation:

A running track has the shape of a rectangle capped with a semicircle on each end

The track is 80 feet wide
The rectangular portion of the track is 90 feet tall

We need to estimate the length around the outside of the track

The length of the outside the track is the length of two semi-circle and two straight lengths of the rectangle

∵ The track is 80 feet wide

- From the figure the width of the track is the diameter of the

semi-circles

∴ The diameter of each semi-circle = 80 feet

∵ The radius of a circle is half its diameter

∴ The radius of each semi-circle = $\frac{1}{2}$ × 80 = 40 feet

∵ The length of a circle = 2πr

∴ The length of a semi-circle = πr

∴ The length of two semi-circle = 2 × πr

- Substitute r by 40

∴ The length of two semi-circle = 2 × π(40) = 80π feet

∵ The rectangular portion of the track is 90 feet tall

∴ The length of the rectangle = 90 feet

∴ The two straight parts of the track = 2 × 90 = 180 feet

- Add the length of the two semi-circles and the two straight

parts to find the length of the track

∵ Length of the track = 80π + 180

- Substitute π by 3.141

∴ Length of the track = 80(3.141) + 180

∴ Length of the track = 431.28 ≅ 431 feet

The length around the outside of the track is about 431 feet

Don Moline, a construction worker, earns $12.25 per hour. He worked his regular 36 1/4 hours last week. What was his straight-ti

Anton [14]

Answer:

The correct answer is US$ 444.06

Step-by-step explanation:

1. Let's check all the information that was provided in the question:

Salary per hour earned by Don Moline = US$ 12.25

Number of hours worked last week = 36 1/4

2. For calculating the payment Don will receive, we do the following:

Straight-time payment = Salary per hour earned by Don * Number of hours worked last week

Straight-time payment = 12.25 * 36 1/4

Straight-time payment = 12.25 * 36.25 (1/4 = 0.25)

Straight-time payment = US$ 444.06

Don Moline will receive US$ 444.06 of payment

Alice has just discovered base 10 cake! She is delighted with how powerful it is. One day, after nibbling on the cake, Alice rea

Romashka [77]

Answer:

5.38 ounces

Step-by-step explanation:

Given that :

Alice height = 1 mile

Distance of earth to moon = 239000 miles

Number of base 10 cakes required so they Alice's head just touches the moon ;

Using the relation :

Distance = height per ounce * 10^number of ounces

Height per ounce = 1 mile ;

Let number of ounces = n

Hence,

239000 = 1 * 10^n

239000 = 10^n

Take log of both sides

Log(239000) = n

5.3783979 = n

5.3784 = n

Hence, Alice should take 5.38 ounces of base 10 cakes

PLSSS HELP I'M DEAD

olga2289 [7]

Answer:

$24

Step-by-step explanation:

You will plug in 8 for x :)

30 - (3/4)x

Since he loses 3/4 a dollar for every hour he can't work, (3/4) x 8 = 6. He will lose 6 dollars from this. 30 - 6 = 24.

His final profit is 24.
