A rectangle has a width of 10 centimeters. The rectangle's length is 4 times its width. What is the perimeter of the rectangle?

Answers

Answer 1

Answer:

Answer:

100 cm.

Step-by-step explanation:

We have been given that a rectangle has a width of 10 centimeters. The rectangle's length is 4 times its width.

The length of rectangle would be $4* 10\text{ cm}=40\text{ cm}$ .

We know that perimeter of rectangle is 2 times the sum of length and width of rectangle.

$\text{Perimeter of rectangle}=2(\text{Length+Width)}$

$\text{Perimeter of rectangle}=2(\text{10 cm+ 40 cm)}$

$\text{Perimeter of rectangle}=2(\text{50 cm)}$

$\text{Perimeter of rectangle}=100\text{ cm}$

Therefore, the perimeter of our given rectangle would be 100 cm.

Answer 2

Answer: If it's width is 10cm then it's legth has to be 40cm. So 10+10+40+40=100cm Perimeter

Answers

The population of a species of rabbit triples every year. This can be modeled by f(x) = 4(3)^x and f(5) = 972.

The 5 that is found inside the function has a significant meaning.
It represents the population of a species of rabbit every year. It substitutes the variable x.

a recipe that yields 12 buttermilk biscuits calls for 2 cups of flour. How much flour is needed to make 30 biscuits

Answers

5 Cups

Because 24 biscuits = 4 cups
12/6=2 cups

Final answer:

To make 30 biscuits, you would need 5 cups of flour.

Explanation:

To find out how much flour is needed to make 30 biscuits, we can set up a proportion using the given information. Since the recipe calls for 2 cups of flour to make 12 biscuits:

2 cups of flour = 12 biscuits

Let 'x' represent the amount of flour needed to make 30 biscuits:

x cups of flour = 30 biscuits

Using cross multiplication, we can solve for 'x':

2 * 30 = 12 * x

60 = 12x

x = 5 cups

Hello! I graduated in 2008 but forgot how to solve multiplication. It's been so long. However I want to be refreshed on solving 44•12

Answers

To do this you first have to set this up vertically.
First you multiply through with the 2 (44×2=88). Then next, you have to multiply through with the 1 (44×1=44) But since this is the second line, you have to add the 0 to the end (440).
Now you simply add 88+440=528.
