Mrs. Mobley can jog 3 miles in 27 minutes. How many miles can she jog in 81 minutes?

Answers

Answer:

9 miles

Step-by-step explanation:

You need to get 27 minutes to 81 minutes so you multiply 27 by 3, and that is 81, so you simply multiply 3 by 3 and get 9! Hope this helps! ;)

(27 x 3) = 81

(3 x3) = 9

Answers

Answer:

x = 1 y = -3 (1, -3)

Step-by-step explanation:

Use the Substitution Method

First, you have to turn the equations into slope intercept form (y = mx + b)

First equation

x - y = 4

subtract x from both sides

-y = -x + 4

divide each side by -1

y = x - 4

Second Equation

4x + y = 1

subtract 4x from both sides

y = -4x + 1

Turn the two new equations into one equation like so

-4x + 1 = x - 4

add 4x to both sides

1 = 5x - 4

add 4 to both sides

5 = 5x

divide each side by 5

x = 1

Fill in x in one of the original equations in order to find the value of y

4(1) + y = 1

4 + y = 1

subtract 4 from both sides

y = -3

The solution is (1, -3)

hope this helps :)

Charlotte and Riley walked 6/10 of a mile to school one day, and then after school they walked 3/8 of a mile to the store. From the store back home was another 2/5 of a mile. How far did the girls walk in all?

Answers

Answer: The girls walked [tex]1\dfrac38[/tex] miles.

Step-by-step explanation:

Given:  Distance from home to school = [tex]\dfrac{6}{10}[/tex] mile

Distance from school to store = [tex]\dfrac38[/tex] mile

Distance from store to home = [tex]\dfrac25[/tex] miles

Total distance = [tex]\dfrac6{10}+\dfrac38+\dfrac25[/tex]

= [tex]\dfrac{6\times4+3\times5+2\times8}{40}[/tex]   [L.C.M.(10,8,5)=40]

= [tex]\dfrac{24+15+16}{40}[/tex]

= [tex]\dfrac{55}{40}[/tex]

= [tex]\dfrac{11}{8}=1\dfrac38[/tex]  miles

Hence, The girls walked [tex]1\dfrac38[/tex] miles.

A cylinder has a base with a radius of 7 cm and a volume of 615.44 cm3. Use 3.14 for π . Write and solve an equation to find the height of the cylinder.

Answers

Answer:

The height is 4 cm

Step-by-step explanation:

V = (pie) x radius² x height

615.44 cm³ = (3.14) x 7² x h

h = 615.44 cm³/(3.14 x 49)

h = 615.44 cm³/153.86

h = 4 cm²

A sculpture is in the shape of a cylinder. The sculpture has a diameter of 10 feet and a height of 21 feet. Which measurement is closest to the total surface area of the sculpture in square feet?

Answers

Answer:did u get the answer?

Step-by-step explanation:sorry

The measurement of total surface area of the sculpture in square feet is 814 square feet.

What is the surface area of a cylinder?

The surface area of a cylinder can be calculated by adding the area of its lateral surface to the sum of the areas of its two circular ends. The formula for lateral surface area is given by: 2πrh

where r is the radius of the circular base and h is the height of the cylinder.

Since the diameter of the cylinder is 10 feet, the radius is 10/2 = 5 feet.

So, the lateral surface area of the cylinder = 2 × π × 5 × 21 = 210π square feet.

The area of each circular end is given by πr². Since the radius is 5 feet, the area of each circular end is π × 5² = 25π square feet.

Therefore, the total surface area of the cylinder is 210π + 2 × 25π = 260π square feet.

The value of π is approximately 3.14, so the surface area of the cylinder is approximately 260 × 3.14 = 816.4 square feet.

So, the closest measurement of the total surface area of the sculpture in square feet is 816 square feet.
