A circular mirror is surrounded by a square metal frame. The radius of the mirror is 2x. The side length of the metal frame is 8

Schach [20]

Answer:

183.43x2

Area of the entire frame = (14x)2 = 196x2

Area of the mirror = pi(2x)2 = 4x2(pi)

Area of the frame surrounding the mirror = (196 - 4pi)x2 = 183.43x2

Trevor is making 2/3 of a recipe for chicken noodle soup. He adds ½ cup of chopped celery. The equation 2/3 c = 1/2 can be used

Nikitich [7]

Answer:

Cups of chopped celery in original recipe = $\frac{3}{4}\ cups$

Step-by-step explanation:

Given that:

Trevor is making 2/3 of a recipe

Number of cups of chopped celery used = 1/2 cup

The following equation can be used to find the original number of cups of chopped celery used in recipe.

$\frac{2}{3}c=\frac{1}{2}$

Multiplying both sides by 3/2

$\frac{3}{2}*\frac{2}{3}c=\frac{1}{2}*\frac{3}{2}\\\\c= \frac{3}{4}\\$

Hence,

Cups of chopped celery in original recipe = $\frac{3}{4}\ cups$

Write the standard form of the line that contains a slope of -1/2 and y-intercept of 1. Include your work in your final answer.

NemiM [27]

The slope intercept form would be y= -1/2x + 1 and to get it into standard form all you have to do is move the -1/2 x to the other side, making it 1/2x + y = 1
