Find the surface area of this rectangular prism.​
Alexeev081 [22]

Answer:

Surface area of the rectangular prism= 168 yards^2

Step-by-step explanation:

Given Dimensions of the rectangular prism are:

Length(L)= 9 yards\\\\Width(w)=2 yards \\\\Height(H)= 6 yards

Surface Area of a rectangular prism=

                                          2(L*W+W*H+H*L)\\\\                                                           =2(9*2+2*6+6*9)\\\\                                                            =2(18+12+54)\\\\                                                             = 2(84)\\\\

                                    =168 yards^2

The surface area of the rectangular prism is 168 yards^2

tell how to get the variable to be on one side of the equation by itself. 6n=72. 6=1.2a. 21/2x = 15 please explain
Vikki [24]

#1 divide by 6n to both sides to get n by itself

#2 multiply both sides by 6/5a to get a by itself

#3 multiply both sides by 2/5x to get x by itself


When you have whole numbers (no decimals) you can divide. When you have numbers with decimals, convert them to fractions and multiply by the reciprocal to get the variable by itself.

Answer:  (x - 3)² + (y + 0.5)² = 3.25    →    (x-3)^2+\bigg(y+\dfrac{1}{2}\bigg)^2=\dfrac{13}{4}

<u>Step-by-step explanation:</u>

Concentric means they have the same center but different radii.

The equation of a circle is:  (x - h)² + (y - k)² = r²    where

  • (h, k) is the center of the circle
  • r is the radius of the circle

Complete the square to find the center of the circle

x² - 6x + _____  + y² + y + _____ = 1 + ____ + ____

    ↓                              ↓

-6/2 = -3                    1/2 = 1/2

Equation: (x - 3)² + (y + 1/2)² = r²

Since the circle passes through point (x, y) = (4, -2), input that into the equation to find r².

(x - 3)² +  (y + 1/2)² = r²

(4 - 3)² + (-2 + 1/2)² = r²

  (1)²    +  (-3/2)²    = r²

   1      +     9/4      = r²

                 13/4     = r²

Equation: (x - 3)² + (y + 1/2)² = 13/4    →   (x-3)^2+\bigg(y-\dfrac{1}{2}\bigg)^2=\dfrac{13}{4}

In decimal form: (x - 3)² + (y + 0.5)² = 3.25
