Answer:

r = 46

Step-by-step explanation:

To solve the equation, solve for r by isolating the variable. Whatever you do to one side, do to the other.

1) First, simplify the right side by combining like terms. Subtract the coefficients of the terms with the same variables. Subtract 5r by 4r.

$60 = 5r-4r + 14\\60 = r + 14$

2) Now, finally isolate r by subtracting both sides by 14.

$60 = r + 14\\46 = r$

So, r = 46.

The recipe for Cesar Salad calls for 3/4 cups of Parmesan cheese. How much is needed to make 1/2 of the recipe? HELP PLEASEEE

kramer

Answer:

To make half the recipe, we will need 3/8 Parmesan cheese.

Step-by-step explanation:

We know that:

Cesar Salad = 3/4 Parmesan cheese

To make 1/2 the recipe, we need to change everything in halves.

Work:

Cesar Salad = 3/4 Parmesan cheese
=> Cesar Salad/2 = 3/4 ÷ 2 Parmesan cheese
=> Cesar Salad/2 = 3/4 x 1/2 Parmesan cheese
=> Cesar Salad/2 = 3/8 Parmesan cheese

Hence, to make half the recipe, we will need 3/8 Parmesan cheese.

Find the perimeter of the stage shaped like a semi-circle (shown below), rounded to the nearest tenth of a foot.

SVEN [57.7K]

Step-by-step explanation:

Hello there, because you did not attached the photo or the information of the diameter of the circle, so I will solve this type of question under a general form

Let's assume d is the diameter of the circle

=> the perimeter of the circle is: dπ

=> the perimeter of the half arc of a circle

= 1/2 perimeter of the circle

= 1/2dπ

Hence, the perimeter of the stage shaped like a semi-circle:

= the perimeter of the half arc of a circle + the diameter

= 1/2dπ + d

= 3/2dπ

Just substitute d into the above expression, you will find out the answer.

Hope it will find you well.
