What is the perimeter of the figure

Brums [2.3K]

Answer:

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The perimeter, P, is: P=x+x+y+y.

After 1 year, $800 deposited in a savings account with simple interest had earned $64 in

stepan [7]

Answer:

8%

Step-by-step explanation:

We will use the equation provided to solve this problem.

$I=Prt$

Lets plug in the values:

$64=800x(1)$ First, divide both sides by 800.

$.08=x(1)$ Multiply x by 1

$x = .08$

Now, we multiply .08 by 100 to get our interest rate:

(.08)100 = 8

The interest rate is 8%

Travis wants to build a fence around his mother's rectangular garden. The length of the garden is 315 centimeters, and the width

Mariulka [41]

Answer: 12.1 meters

Step-by-step explanation:

This is a rectangular fence so it represents a rectangle.

Fencing the garden will require going around it therefore you are looking for the perimeter.

Perimeter of a rectangle = (2 * Length) + ( 2 * Width)

= (2 * 315) + ( 2 * 290)

= 1,210 cm

Convert to meters:

A meter is 100 centimeters

= 1,210 / 100

= 12.1 meters

A bear can run up to 18.47 feet per second. How many feet could the bear run in 3.9 seconds? 720.33 feet 7,203.3 feet 72.033 fee

JulsSmile [24]

Answer:

72.033 ft

Step-by-step explanation:

To find this, let us set up a fraction. Since 18.47 = 1 second, y = is 3.9 seconds. Let "y" be the variable.

$\frac{18.47}{1}=\frac{y}{3.9}$

Step 1: Switch sides

$\frac{y}{3.9}=\frac{18.47}{1}$

Step 2: Apply rule: $\frac{a}{1}=a$

$\frac{y}{3.9}=18.47$

Step 3: Multiply both sides by $3.9$

$\frac{3.9y}{3.9}=18.47\cdot \:3.9$

Step 4: Simplify

$y=72.033$

The bear can run 72.033 feet in 3.9 seconds
