If V = 12R / (r + R) , then R =

Answers

$V=(12R)/(r+R)\n\nV(r+R)=12R\n\nVr+VR=12R\n\nVR-12R=-Vr\n\n(V-12)R=-Vr\ \ \ \ /:(V-12)\neq0\n\nR=(-Vr)/(V-12)\n\nR=(Vr)/(12-V)$

vr+vR=12R
vr=12R-vR
vr=R(12-v)
R=vr/12-v

A snack tray at a party has cheese squares with 2 grams of protein apiece and turkey slices with 3 grams of protein apiece. Which inequality represents the possible ways Nina can eat 12 or more grams of protein, if x is the number of cheese squares that she eats and y is the number of turkey slices that she eats?12 ≤ x + y
12 ≥ x + y
12 ≤ 2x + 3y
12 ≥ 2x + 3y

Answers

The inequality that represents the possible ways Nina can eat 12 or more grams of protein is 12 ≤ 2x + 3y, where x is the number of cheese squares that she eats and y is the number of turkey slices that she eats. In equation, 12 ≤ 2(2) + 3(3) to 12 ≤ 4 + 9 to 12 ≤ 13.

Find the area of the shaded region. Round your answer to the nearest hundredth.

Answers

4 semicircles of 90º=1 circle

Area of the shade region=area of the square - area of a circle

1)we calculate the area of the square.
area of a square =slide²
slide=8 m

area of a square=(8 m)²=64 m².

2) we calculate the area of the circle:
area of a circle=πr²
r=4 m

area of a circle=π(4 m)²=16π m²≈50.27 m²

3) we calculate the area of the shaded region:

Area of the shaded region=64 m² - 50.27 m²=13.73 m²

answer:The area of the shaded regios is 13.73 m²

8 times 8 is 64 so rounded to the neArest hundreth it is 100

What is the area of a Square?

The area of a square is (side*side)

The area is the sum of the areas of its faces.

The areas of the base, top, and lateral surfaces i.e all sides of the object. It is measured using different area formulas and measured in square units and then adding all the areas.

The area of a solid object is a measure of the total area that the surface of the object covers.

A^2 - 49 solve the equation by factoring

Answers

Answer:

Step-by-step explanation:

To solve the equation a^2 - 49 by factoring, we can use the difference of squares formula. The difference of squares formula states that a^2 - b^2 can be factored as (a + b)(a - b).

In this case, a^2 - 49 can be rewritten as (a + 7)(a - 7).

By setting each factor equal to zero, we can solve for a:

a + 7 = 0

a = -7

a - 7 = 0

a = 7

Therefore, the solutions to the equation a^2 - 49 = 0 are a = -7 and a = 7.

Answer:(A+7)(A−7)

Step-by-step explanation:

Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) where a=A and b=7.
