(1d) Instructions for a craft project say that the length of a piece of red ribbon should be 7 inches less than the length of a piece of blue ribbon. How long is the BLUE ribbon if the length of the RED ribbon is 12 inches? *

Answers

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!

What is the value of x?

Answers

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]

[tex]\tt 9x=90[/tex]

D) None of the above

Answers

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.

Answers

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]

[tex]16+\frac{2}{10} =\frac{81}{5}[/tex] which is 16.2

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

1,120 ft^2

5,760 ft^2

1040 ft^2

976 ft^2

Answers

Answer:

c

Step-by-step explanation:

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

What is the total surface area of the pyramid?

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.

Dean and his friends went to Aqua World Water Park, where they floated down the Lazy River for 1 2 of an hour. This was 1 4 of the total time Dean and his friends spent at Aqua World. Use an equation to find the total amount of time Dean and his friends spent at the park. To write a fraction, use a slash ( / ) to separate the numerator and denominator.

Answers

1/2 of an hour is 30 minutes
That’s 1/4 of the total amount of time they spent in the park
So, 30 minutes x 4 would be 120 minutes or 2 hours which means they spent 2 hours at the water park

Jayden correctly simplifies the expression 9x(2+7x) using the following steps Step 1. 9(7x+2) Step 2. 9(7x) +9(2) Step 3. (9x7)x+18. What are the properties for each one?

Answers

How to solve:

    Let's follow his process step-by-step to analyze what property is being used. The breakdown is as follows:

Process:

Jayden's work

Set up equation                                                     9(2 + 7x)

Step 1                                                                      9(7x + 2)

Step 2                                                                     9(7x) + 9(2)

Step 3                                                                      (9*7)x + 18

Breakdown

Set up equation                                                     9(2 + 7x)

Step 1: Commutative Property of Addition

This property states that when adding, the order of the numbers being added does not matter, and are therefore interchangeable.

Original equation: 9(2 + 7x)

Equation's formula: a(b + c)

Changed equation: 9(7x + 2)

Equation's formula: a(c + b)

By swapping the b and c values in the parentheses, Jayden is demonstrating the Commutative Property. Both will still produce the same sum.

Step 2: Distributive Property of Multiplication

This property states that the sum of two addends that are multiplied by the same number is equal to the product of that number multiplying the sum of both addends.

Original equation: 9(7x + 2)

Equation's formula: a(c + b)

Changed equation: 9(7x) + 9(2)

Equation's formula: a(c) + a(b)

By splitting the parentheses and multiplying each term separately, Jayden is demonstrating the Distributive Property. Both will produce the same product.

Step 3: Associative Property of Multiplication

This property states that the product of three terms, where one is outside of the parentheses multiplying the other two, is not affected by changing which term is on the outside of the parentheses.

Original equation: 9(7 * x) +18

Equation's formula: a(c*x) + (ab)

Changed equation: x(7*9) + 18

Equation's forumula: x(c*a) +18

By swapping the 9 and x variables, Jayden is demonstrating the Associative Property. Both will produce the same product.

Simplified:

Step 1 - Commutative Property

Step 2 - Distributive Property

Step 3 - Associative Property
