The area of a circle is 379.94m². Using 3.14 for π, find the circumference of the circle.
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.

Step-by-step explanation:
work out the product 2 2/3 and 1 5/7
give the answer as a mixed number
Answer:
= 3 5/9
Step-by-step explanation:
2 2/3 × 1 5/7
= 8/3 × 12/7
= (8×12) / (3×7)
= 96/27
= 3 15/27
= 3 5/9
2 2/3 × 1 5/7 = 3 5/9
solve x-5y=-30, 3x+5y=10 show your work
1) x = 5y - 30
2) x = - 1.6y + 3.3
im assuming these are 2 different questions
Explanation:1)Start with the equation:
x - 5y= -30
add 5y to both sides:
x = 5y - 30
Your answer is x = 5y - 30
2)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

A pool is 10 feet wide. It is three times as long as it is wide. What is the perimeter of the pool? *
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

-2x > -12
Step 2: Solve for x
Divide -2 on both sides: x < 6Here 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.
Solve for x-2x > -12-2x / -2 < -12 / -2 (flip the sign!)x < 6The solution set for x is all values less than 6.

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.

Can someone help me on 2/3-3/8 show work
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

HELP, NO SCAM ANSWERS PLEASE!
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

-7x = -10x + 10
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
