dlinn [17]

Answer:

<h2>The scale factor is 285.7143 ≅ 286.</h2>

Step-by-step explanation:

The square sheet has an area of 100 square meters.

Hence, the width of the sheet is \sqrt{100} = 10 meters.

The scale factor is needs to be in such a way, so that the film's wide will be match perfectly with the square sheet. Hence, 35x millimeters = 10 meters = 10000 millimeters .

x = \frac{10000}{35} = 285.7143.

Natalka [10]

Hello!

ANSWER

The painting would cost $387.45.

____________________________________________________________

EXPLANATION

2' 3" = 27"

3' 5" = 41"

Multiply the length by the width (in inches) of the painting.

27 * 41 = 1107

We now know that the area of the painting is 1107in.^{2} Next, multiply the cost per square inch (0.35) by the total amount of square inches (1107).

.35 * 1107 = 387.45

Help I’ll give you 30 points
Gnesinka [82]

Answer:

a) 16.25 centimeters

b) 6.8 centimeters

Step-by-step explanation:

We can set up a proportion for both of these problems.

a) Look at the longest side of each triangle. We can set up a fraction: 7.2/18. We can also set up a fraction for XZ and PR:

6.5/x

x represents the length you're trying to find.

Since the triangles are similar, we have an equation:

7.2/18=6.5/x

Cross multiply

16.25

XZ is 16.25 centimeters long.

b)

We can do same thing:

7.2/18=x/17

Cross multiply

6.8

QR is 6.8 centimeters long.

Hope this helps!
