Autumn has 6 ribbons for her hair. Each ribbon is 3 feet long. How many total inches of ribbon
does Autumn have?

Answers

Answer:

she has a total of 216 inches of ribbon

Step-by-step explanation:

1 foot is equal to 12 inches.

if she has 3 feet per ribbon, and each foot is 12 inches, then 3 × 12 would be 36, making each ribbon 36 inches.

But, she has 6 pieces of ribbon, so that's 36 inches 6 times. 6 × 36 is 216, so she has a total of 216 inches of ribbon.

Multiply the 6 ribbons by the 3 feet for each and you get 18 feet. Then take the 18 and multiply it by 12 since there is 12 inches in a foot, and you get 216 inches for your answer

Hi!! Please explain how you got the answer, thanks!! :)) ​

Start out by finding the area of the square.

a = 4²

a = 16

Since all we have to look at is 1/4 of this square, multiply the area by 1/4.

(16)1/4

4

The area of the triangle is 4.

Now we need the area of the circle.

a = πr²

Sub: a = π(2)²

a = π(4)

Since the portion of the circle that covers the triangle is 1/4 of the circle, subtract 1/4 of the area of the circle from the area of the circle.

a = 4 - 1/4(π(4))

a = 4 - 1/4π x 1

a = 4 - 1/4π

Now this is where it's supposed to go, considering the fact that π isn't given a value.

Normally, I'd use 3.14 for π, as the entire population would, and then it would be easy, but obviously that isn't an option.

Now this answer isn't up there, so my best option is to tell you it's most likely c, and I hope I'm right.

find the perimeter of these figures *
please*

Answers

Answer:

The perimeter of figure a is 44 inches, the perimeter of figure b is 72 inches.

Step-by-step explanation:

The sides of figure a is 8; 2; 3; 12; 2; 12; 3; 2, to get the perimeter, add all the sides together, which will be 8 + 2 * 2 + 3 * 2 + 12 * 2 = 8 + 4 + 6 + 24 = 12 + 30 = 42 inches. The sides of figure b is 3; 3; 3; 3; 13; 13; 5; 5; 5; 5; 7; 7, to get the perimeter, add all the sides together, which will be 3 * 4 + 13 * 2 + 5 * 4 + 7 * 2 = 12 + 26 + 20 + 14 = 32 + 40 = 72 inches.

Answer:

a) 44

2 + 8 + 2 + 8 + 12 + 12 = 44

b) 72

13 + 13 + 3 +3 +3 +3 +5 +5 +5 +5 +7 +7 = 72

Last year, 85% of students participated in the school fundraiser. Using this data, what would be the BEST prediction of how many of the 320 students will participate in the fundraiser this year?

Answers

Answer:

C. 272

Step-by-step explanation:

Since we know 85% of the students participated last year we can assume the same amount will participate this year so to find the answer you simply do the total number of students (320) multiplied by 85% or .85 to get the best guess of how many students will participate this year.

It’s 272because you would multiply 320 by .85 and you will get 272

Answers

Answer:

z = 47.2°

w = 42.8°

y = 42.8°

x = 47.2°

Step-by-step explanation:

found altitude ('h') first:  6/h = h/7;  h = [tex]\sqrt{42}[/tex]

found base by using Pythagorean Theorem:

7² + ([tex]\sqrt{42}[/tex])² = c²

c = [tex]\sqrt{91}[/tex]

found angle z using Rule of Sines:

sin 90 / [tex]\sqrt{91}[/tex] = sin z / 7

arcsin z = 7 / [tex]\sqrt{91}[/tex] = 47.2°

found angle w by adding 90 and 47.2, then subtracting from 180 to get 42.8°

found angle y by subtracting m∡z from 90° to get 42.8°

found angle x by adding 90 and 42.8°, then subtracting from 180

You pay $3 per square foot for carpeting. Which equation can be solved to find the
amount you will pay to cover a triangular section of the floor with a base of 2 yards and
a height of 5 yards?

Answers

Answer:

$135

Step-by-step explanation:

Step 1

Conversion

Base = 2 yards

1 yard = 3 feet

2 yards = x

Cross Multiply

x = 2 × 3 feet = 6 feet

Height = 5 yards

1 yard = 3 feet

5 yards = x

Cross Multiply

x = 5 × 3 feet = 15 feet

Step 2

Find the area of the triangle

Area of a triangle = 1/2 × base × height

Base = 6 feet

Height = 15 feet

Area = 1/2 × 6 × 15

= 45 square feet

Step 3

Find the cost of the carpet

1 Square foot = $3

45 square feet = x

Cross Multiply

x = 45 × $3

x = $135

Therefore, the amount you will pay to cover a triangular section of the floor is $135
