If a circle has circumference 100pi units, what is it’s area
const2013 [10]

Answer:

2500pi^2 units

Step-by-step explanation:

Circumference = pi * diameter

Circumference = pi * 100

Radius = diameter/2

Radius = 50

Area = pi * radius^2

Area = pi * 50^2

Area = pi * 2500

Area = 2500pi^2 units

Find a rational number between 3/5 and 4/5 ( see I just only want one so please don't give me all five)
goldenfox [79]

Answer:

\dfrac{7}{10}

Step-by-step explanation:

We need to find a rational number between 3/5 and 4/5.

We can find a rational number between two fractions as :

\dfrac{a+b}{2}

We have, a = 3/5 and b = 4/5

So,

\dfrac{\dfrac{3}{5}+\dfrac{4}{5}}{2}\\\\=\dfrac{\dfrac{7}{5}}{2}\\\\=\dfrac{7}{10}

So, a rational number between 3/5 and 4/5 is equal to 7/10.

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:

<u>The correct answer is US$ 444.06</u>

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

<u>2. For calculating the payment Don will receive, we do the following:</u>

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

<u>Don Moline will receive US$ 444.06 of payment</u>

Hello!) this is math :( Can you help me please?
Zarrin [17]

The standard form: Ax + By = C.

The point-slope form:

y-y_1=m(x-x_1)

6. We have m =-2 and the point (-7, -10). Substitute:

y-(-10)=-2(x-(-7))\\\\y+10=-2(x+7)\qquad|\text{use distributive property}\\\\y+10=(-2)(x)+(-2)(7)\\\\y+10=-2x-14\qquad|-10\\\\y=-2x-24\qquad|+2x\\\\\boxed{2x+y=-24}

7. We have m = 4 and the point (-3, 0). Substitute:

y-0=4(x-(-3))\\\\y=4(x+3)\qquad|\text{use distributive property}\\\\y=(4)(x)+(4)(3)\\\\y=4x+12\qquad|-4x\\\\-4x+y=12\qquad|\text{change the signs}\\\\\boxed{4x-y=-12}
