PLZZ HELP ASAP !!! HURRY !!!

Ruby is decorating for a party and needs 120 meters of ribbon. At the party supply store, the ribbon is sold in rolls. Each roll contains 25 feet of ribbon. How many rolls will Ruby need to purchase? (1 meter is approximately 39.37 inches)

A. 16 rolls

B. 14 rolls

C. 12 rolls

D. 10 rolls

Answer:

B

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 13² + 4² = 169 + 16 = 185 ( take the square root of both sides )

x = [tex]\sqrt{185}[/tex] ≈ 13.6 ( to 1 dec. place ) → B

Answer:

-5

Step-by-step explanation:

The initial value is also known as the y-intercept (in other words, the output value when the input of a linear function is zero). In the equation;

y = mx + b

The variable b represents the y-intercept because the x-value is equal to zero. By applying this to our equation, we get:

y = mx + b

y = -2x - 5

And thus, (-5) is our answer. Good luck and keep studying!

Answer:

y = x - 4

move y to the right side and 4 to the left side

and you will get

4 = x - y which is the same as x - y = 4

The value of the equation is x + ( -y ) = 4

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

y = x - 4   be equation (1)

On simplifying the equation , we get

Adding 4 on both sides of the equation , we get

x = y + 4

Subtracting y on both sides of the equation , we get

x - y = 4

Therefore , the value of A is x - y = 4

Hence , the equation is x + ( -y ) = 4

Step-by-step explanation:

12/6=2 & 2/6=0.33.

Answer:

as it is isosceles triangle

40+40+x=180

x = 100°

Given:

Employee earns $10.90 per hour for the first 40 hours he works in 1 week.

He is paid 1.5 times that rate for each additional hour that he works.

To find:

How much money does he earn working for 43 hours in 1 week?

Solution:

Earning for first 40 hours = $10.90 per hour

Earning for additional hours after 40 hours = 1.5 × $10.90 per hour

                                                                        = $16.35 per hour

In 43 hours, 3 hours are additional after first 40 hours.

Earning for first 40 hours = 40 ×  $10.90

Earning for additional 3 hours = 3 ×  $16.35

Now,

[tex]\text{Total earnings}=40\times 10.90+3\times 16.35[/tex]

[tex]\text{Total earnings}=436+49.05[/tex]

[tex]\text{Total earnings}=485.05[/tex]

Therefore, the total earnings for 43 hours in a week is $485.05.

Answer:

y = x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c )

Given

3y - 3x = 21 ( add 3x to both sides )

3y = 3x + 21 ( divide all terms by 3 )

y = x + 7 ← in slope- intercept form

Answer:

Sum of those numbers are 50

Step-by-step explanation:

Let x represent a number that is twice as far away from 13 than 22.

The number can't be less than 13 but will be between 13 and 22 or slightly more than 22 otherwise it will be far away from both.

Thus;

|x - 13| = 2|x - 22|

It's in absolute form, so we will square both sides to get rid of the absolute brackets.

Thus;

(x - 13)² = 4(x - 22)²

x² - 26x + 169 = 4(x² - 44x + 484)

x² - 26x + 169 = 4x² - 176x + 1936

4x² - x² - 176x + 26x + 1936 - 169 = 0

3x² - 150 + 1767 = 0

Using quadratic formula, we have;

x = 19 or x = 31

Thus,the sum of the 2 numbers = 31 + 19 = 50
