Answer:

19 inches

Step-by-step explanation:

Since the blue ribbon needs to be 7 inches longer than the red ribbon, add 7 to 12 to get 19 inches total.

Hopefully this helps- let me know if you have any questions!

Hey there!

Let's make an equation 28evbar01

=> Convert word problem into equation

7 - x = 12

x = 12 + 7

x = 19

Therefore, Blue ribbon is 19 inches

Answer:

B

Step-by-step explanation:

First you find the amount of people at the reunion which was 80. Then you find 25% of 80. 25% of 80 is 20. The only age group with 20 people is the 20-29 year olds.

let's write 2*2*2*2*2*2*2*2*2 in exponential form.

Notice 2 has been multiplied times itself 9 times.

Basic exponential notation:-

[tex]\sf{2*2=2^2}[/tex]

[tex]\sf{2*2*2=2^3}[/tex]

[tex]\sf{2*2*2*2=2^4}[/tex]

You should notice a pattern.

This is the pattern:-

The number of times 2 has been multiplied times itself is the exponent.

In this case, we multiplied 2 times itself 9 times.

Hence, the answer is

[tex]\bigstar{\boxed{\pmb{2^9}}}[/tex]

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I'll comment and/or edit my answer :)

Answer:

16.2 = [tex]\frac{81}{5}[/tex] and 121 = [tex]\frac{121}{1}[/tex]

Step-by-step explanation:

16.2 can be simplified to its fraction form, which is [tex]\frac{81}{5}[/tex]

121 is already simplified since it is a whole number, but its fraction form would be [tex]\frac{121}{1}[/tex]

Answer:

Fractions have different applications in the real word. We can interpret them as parts of a whole in recipes, sports team performance, test scores, time, and pizza slices in a pie. They can also be interpreted as decimals and percentages.

Step-by-step explanation:

Hope this helps!

All the correct methods to interpret fractions is,

Fractions as parts of wholes or parts of sets;

Fractions as the result of dividing two numbers;

Fractions as the ratio of two quantities;

Fractions as operators; and fractions as measures.

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

To find the method for interpret fractions.

Since, Fractions have different applications in the real word.

Hence, We can interpret them as parts of a whole in recipes, sports team performance, test scores, time, and pizza slices in a pie.

======================

1 hours → 75 miles

? hours → (1125/75)

It takes her 15 hours to drive 1125 miles.

Answer:

15 hours

Step-by-step explanation:

Finding how much distance in 1 hour

⇒ Ceci = 225 miles = 3 hours

⇒ 225 miles = 3 hours

⇒ 225/3 miles = 3/3 hours

⇒ (25 x 9)/3 miles = 1 hour

⇒ (25 x 3) miles = 1 hour

⇒ 75 miles = 1 hour

Finding how much hours in 1125 miles

⇒ 75 miles = 1 hour

⇒ 75x miles = 1125 miles = x hours

⇒ 75x/75 = 1125/75

⇒ x = 15

⇒ 75(15) miles = 1125 miles = (15) hours

⇒ 1125 miles = (15) hours

Answer:

Step-by-step explanation:

The surface area of the square pyramid is 1040 ft² in the given figure.

The total surface area of the given pyramid can be expressed as:

Surface area of a square pyramid = A + (1/2) p × s

where A is the base area, p is the perimeter of the base, and s is the slant height

As per the question, we have

length (l) = 20 ft

base perimeter (p) = 4l = 4 × 20 = 80 ft

base area (A) = l² = 20² = 400 ft²

slant height (s) = 16 ft

Substitute the values in the formula for surface area:

Surface area = 400 + 1/2 × 80 × 16

Surface area = 400 + 1280/2

Surface area = 400 + 640

Surface area = 1040 ft²

Thus, the surface area of the square pyramid is 1040 ft².

Answer:

x = 10

Step-by-step explanation:

the two angles shown are supplementary, they add up to 180 degrees

so we can write this equation to solve for 'x':

100 + 9x - 10 = 180

90 + 9x = 180

9x = 90

x = 10

Answer:

[tex]\tt x=10^o[/tex]

Step-by-step explanation:

The given angles are supplementary angles, meaning they add up to 180°.

[tex]\tt 100+ 9x - 10 = 180^o[/tex]

[tex]\tt 90 + 9x = 180^o[/tex]

[tex]\tt 90+9x-90=180-90\:\: (Subtract)[/tex]

Answer:

D) None of the above

Step-by-step explanation:

Let's use process of elimination!

A) Vertical angles are opposite angles formed by two intersecting lines. These two are adjacent, therefore rendering this statement false.

B) Complementary angles are two adjacent angles that add up to 90 degrees. There is no proof that m∠a+∠b=90°, therefore this statement is false.

C) Supplementary angles are two adjacent angles that add up to 180 degrees. Assuming A∈ED, this statement is false as well.

D) None of the answers above are correct.
