Answer:

k = 1.5

Step-by-step explanation:

In order to isolate your variable, k, you need to do inverse operations. Since k is being multiplied by 78, you want to divide both side by 78.

k x 78 = 117

k x 78/78 = 117/78

k x 1 = 1.5

k = 1.5

The distance between City A and City B is 500 miles. A length of 1.8 feet represents this distance on a certain wall map. City C
Ratling [72]

Answer: 800 miles

Step-by-step explanation:

Let the actual distance between City C and City​ D be represented by x.

The information given in the question can be formed into an equation as:

1.8 feet / 2.88 feet = 500 miles / x

Cross multiply

1.8 × x = 500 × 2.88

1.8x = 1440

x = 1440/1.8

x = 800

Therefore, the actual distance between City C and City​ D is 800 miles.

The 60$ system had a greater percentage decrease because it was a lower number to begin with. Taking the same portion out of two different numbers will always be a greater decrease for the lower number.

Gabriel wants to paint the model. How
enyata [817]

Answer:

<h2>The area of the base is 144 square inches.</h2><h2>The area of each triangular face is 66 square inches.</h2><h2>Grabiel needs 408 square inches of paint.</h2>

Step-by-step explanation:

The complete problem is attached.

Notice that the figure is a square pyramid, where its base dimensions are 12 inches by 12 inches, which represents an area of

B=12 \times 12 = 144 \ in^{2}

The slant height of the pyramid is 11 inches, which allow us to find the area of each triangle face

A=\frac{1}{2}bh =\frac{1}{2}(12)(11)= 66 \ in^{2}

But there are four triangle faces, so A_{faces} =4(66)=264 \ in^{2}.

Therefore, the area of each triangular face is 66 square inches.

So, the total surface area would be the sum

S=144+264=408 \ in^{2}

Therefore, Gabriel needs 408 square inches to paint the whole model.
