Answer:

69.08

Step-by-step explanation:

The equation for circumference is C = 2πr and the equation for area is A = πr^2. First, do 379.94 = 3.14r^2. This means that r^2=121 so r=11. Now plug it in to C=2πr so it becomes C=2π(11). So C=22π or 69.08.

Question:

Find the circumference of the circle. Use 3.14 for π.

5 in.

Answer:

15.7 inches

Step-by-step explanation:

Identify the diameter of the circle.

d = 5 in.

Use the formula.

C = πd

C = π(5) Substitute 5 for d.

C ≈ 3.14(5) Substitute 3.14 for π.

C ≈ 15.7 Multiply.

The circumference of the circle is about 15.7 inches.

Answer:

The perimeter is 80

Answer:

P = 80

Step-by-step explanation:

w = 10

L = 10 x 3

L = 30

P = L + L + w + w

P = 30 + 30 + 10 + 10

P = 80

Answer:

y=k5, 448 after an 8 hour shift

Step-by-step explanation:

The amount of money he will earn for an 8-hour shift is Php448

Let the amount  of money he earns be A

Let the number of hours worked is "h"

If the amount  of money he earns varies directly to the number of hours worked is expressed as:

A = kx

k = A/x

GIven that A = Php 280.00, x = 5 hours

k = 280/5

k = 56

If x = 8 hours, the amount of money A = kx

A = 56 * 8

A = Php448

Hence the amount of money he will earn for an 8-hour shift is Php448

Answer:

x=10/3

Step-by-step explanation:

Let's solve your equation step-by-step.

−7x=−10x+10

Step 1: Add 10x to both sides.

−7x+10x=−10x+10+10x

3x=10

Step 2: Divide both sides by 3.

3x 3=10 3

x=10/3

Answer:

400

Step-by-step explanation:

Answer: 10

Step-by-step explanation:

1) x = 5y - 30  

2) x = - 1.6y + 3.3

im assuming these are 2 different questions

Start with the equation:

x - 5y= -30

add 5y to both sides:

x = 5y - 30

Your answer is x = 5y - 30  

Start with the equation:

3x+5y=10

subtract 5y from both sides:

3x = -5y + 10

divide by 3 to get x singular

x = - 1.6y + 3.3

Your answer is x = - 1.6y + 3.3

Answer:

b

Step-by-step explanation:

if you say 1<2 and multiply both by negative 3 you will have -3 > -6

Answer:

Step-by-step explanation:

When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number. You can also consider this with a number line.

Step 1: Define

-2x > -12

Step 2: Solve for x

Here we see that any value x smaller than 6 would work as a solution to the inequality.

Answer:

x < 6

Step-by-step explanation:

Hello!

We can solve inequalities the same way as we solve equations. The most important rule is that when you divide or multiply both sides by a negative number, flip the sign.

The solution set for x is all values less than 6.

Answer:

x = 168

Answer:

c = 2.99m+ 6.85

Step-by-step explanation:

one time fee of 6.85

2.99 per movie rental

in other words you must pay 6.85

and 2.99 times the number of movies you watch

m = movies watched

c = cost

therefore

c = 2.99m+ 6.85

watching 13 movies at movie mania would mean that m (movies watched) would be 13

put that into the equation:

c = 6.85+ 2.99(13)

c =  6.85+ 38.87

c = 45.72

Answer:

It is 7/24

Step-by-step explanation:

So first you want a common denominator so we have to find the least common multiple of 3 and 8, which is 24.

Next you have to multiply the same to the numerator, I usually go by the phrase whatever you do to the bottom you do to the top. So 8 times 2 is 16 and 3 times 3 is nine.

Everything changed should be 16/24-9/24

then we do 16-9 is 7 and you never subtract the denominators so 2/3-3/8 is 7/24
