the area of a circle is 36pi cm^2, what is the radius of the circle

Answers

Answer 1

Answer:

6

Step-by-step explanation:

Answer 2
So, to find the area of the circle you use the equation pi r^2, so we need to do this in reverse to find the radius, r.
So we can set up this equation:
36pi = pi r^2
So if we divide by pi on both sides we get
36 = r^2
Then we square root both sides:
6 = r
So the radius is 6cm

Bridget went fishing with her dad. Bridget Bridget caught the first fish of the day, another was 2 more than 3 times the weight of the first fish, the next was 1/2 the weight of the first fish, and the last was 3/5 the weight of the first fish.
Bridget's dad caught four fish. the first fish he caught weighed 2 more than 3 times a weight of the first fish caught that day. one fish weighed 4/5 in the weight of the first fish caught that day, one weighed 4 more than 2 times the weight of the first fish caught that day, and the last one weighed 1/2 the weight of the first caught that day.

if all the fish Bridget caught have the same total weight as the fish her dad caught, then the first fish Bridget caught weighed ____ ounces in the first fish her dad caught weighed ____ ounces.​

Answers

Answer:

Bridget's first fish =f = 5 ounces

Bridget's dad first fish weighs 17 ounces

Step-by-step explanation:

Solution:

Bridget's fishes:

f ounces

2f ounces

3f+2 ounces

1/2f ounces

3/5f ounces

Total= f +2f + (3f+2) + 1/2f +3/5f

=3f + 3f + 2 + 5f+6f/10

=6f + 2 + 11f/10

=60f+11f/10 +2

=71/10f +2

Bridget's dad fishes

3f+2

4/5f

2f+4

1/2f

Total =(3f+2) + (2f+4) + 4/5f +1/2f

=3f+2+2f+4 + 8f+5f/10

=5f + 6 + 13/10f

= 50f+13f/10 + 6

=63/10f +6

Equate the total weight

71/10f +2=63/10f +6

Collect like terms

71/10f - 63/10f =6-2

71f-63f/10 = 4

8f/10=4

Cross product

8f=40

Divide both sides by 8

f=5

Bridget's first fish =f = 5 ounces

Bridget's dad first fish = 3f +2

=3(5)+2

=15+2

=17 ounces

Bridget's dad first fish weighs 17 ounces

Step-by-step explanation:

Here is the complete question

A toy has various shaped objects that a child can push through matching holes. The area of the square hole is 18 square centimeters. The volume of a​ cube-shaped block is 729 cubic centimeters. a. Which edge length can be​ found? Explain. b. Will the block fit in the square​ hole? Explain.

Solution

a.

Since the volume of the cube 729 cm³ is a perfect cube of 9 cm and the area of the square hole which is 18 cm² is not a perfect square, the edge length of the cube-shaped block is easily found.

b. Since the edge length of the block is 9 cm, the area of one of its faces is (9 cm)² = 81 cm² which is greater than the area of the square hole which is 18 cm². Since their dimensions are not the same, the cube-shaped block will not fit into the square hole.

x = 20

Step-by-step explanation:

You're in luck I take H geometry.

What I'm going to do is this. 4x - 18 and 3x + 2 are alternate interior angles so they equal the same, so use this equation.

4x -18 = 3x + 2 (add 18 on both sides)

4x = 3x + 20 (minus 3x on both sides)

x = 20

plug in

4(20) - 18 = 3(20) + 2

80 - 18 = 60 + 2

Solve 3(y-2)=6(y-1)-3y

Answers

Answer:

All real numbers are solutions.

Step-by-step explanation:

1. First you want to distribute what is inside the parenthesis. You would want to do 3 × y + 3 × -2 = 6 × y + 6 × -1 -3y.

2. Now that the equation has been distributed, you want to simplify it. 3 × y is equal to 3y, and 3 × -2 is equal to -6. So, 3y + -6 = 6 × y + 6 × -1 -3y.

3. Now you want to simplify the right side of the equation. So, 6 times y is equal to 6y, and 6 × -1 is equal to -6. Now the new equation is 3y + -6 =6y + -6-3y.

4. Also in an equation, if there is a + and - sign together like this +-, it would equal to -. So, 3y + -6 = 6y + -6-3y, is equal to 3y - 6 = 6y -6-3y.

5. Now you want to combine like terms on the right side of the equation. 3y - 6 = 3y -6 because 6y-3y is equal to 3y.

6. Now the rest of the equation has to be combined using like terms. Start by moving the -3y fromthe right side of the equation to the 3y on the left side of the equation. -3y plus 3y is equal to zero so it cancels out. The 3y on the left side plus another 3y is equal to 6y.

7. Now the equation is 6y - 6 = 6y - 6

8. You can add 6 to the -6 on both sides of the equation which would cancel out on both sides leaving you with an equation of 6y = 6y.

9. Divide both sides by 6 to get y = y.

10. This equation means that all real numbers are solutions to this equation. In other words, no matter what real number you use in this equation, it would come out to be true. For example, if y = 3, 3 = 3, so the equation is true.

find the slopes of the linear equations

Answers

Answer:

m is the slope.

b is the y intercept.

slope intercept is in the form: y = mx + b.

y - 4 = 3 (x - 2) [m = 3] [slope is 3]

y = 3/4x - 7 [m = 3/4] [slope is 3/4]

y + 8 = -6 (x - 1) [m = -6] [slope is -6]

y = -5x + 10 [m = -5] [slope is -5]

4x + 5y = 20 [m = -4/5] [slope is -4/5]

Explanation:

For all of these equations, make sure they are all in slope intercept form by isolating y completely, and getting it on the left side of the equation.

y - 4 = 3 (x - 2) → y - 4 = 3x - 6 → y = 3x - 2 → y = mx + b.y = 3/4x - 7 → y = mx + by + 8 = -6 (x - 1) → y + 8 = -6x + 1 →. y = -6x - 7 → y = mx + by = -5x + 10 → y = mx + b4x + 5y = 20 → 5y = -4x + 20 → y = -4/5x + 4 → y = mx + b

Waterco is filling barrels with waste water at the rate of 8 quarts per hour. The recycling facility picks up 150 barrels on each trip, and each barrel holds 15 quarts of wastewater. How many days are between each pick up? Show your work to receive full credit. Round answer to the tenths place 

Answers

Answer:

11.7 days

Step-by-step explanation:

Given that:

Filling rate = 8 quarts per hour

150 barrels picked up per trip

One barrel = 15 quarts of waste water

Barrel picked up per trip = 150 barrels

Number of quarts per barrel = 15 quarts

Total quantity of waste water = (150 * 15) = 2250 quarts

Filling rate = 8 quarts per hour

Time taken = quantity / rate

Time taken in days = 2250 quarts /(8*24) = 11.72

11.7 days
