Answer:

38 inches

Step-by-step explanation:

since we are finding the diagonal we are going to use the equation a^2+b^2=c^2

so if we do substitution we would have 32^2+20^2=C^2

32^2= 1024

20^2= 400

so,

1024 + 400 = C^2

1424 = C^2

to get rid of the C^2 we have to take the square root of it. But whatever we do on one side of the equation we have to do on the other side so,

C = sqrt(1424)

C = 37.73

C = 38 inches

A scale drawing has a scale of 5mm : 1cm. What is the scale factor?
san4es73 [151]

First you need to convert them to the same unit. 1 cm is 10 mm, so the scale is 5:10. 5*2 is 10, so the scale factor is 2.

A plumber has a 2.5 metre long copper pipe
Anastaziya [24]

We have an object measured in <u>Meters</u>, and we want to cut sections of it off in <u>Centimeters</u>, a different unit of measurement.

Because we're subtracting sections of the pipe, we want to make the units the same, this will make our calculations easier.

1 Meter = 100 Centimeters, so, <u>2.5 Meters = 250 Centimeters</u>

We're cutting ( 60 Cm + 35 Cm + 90 Cm ) off, which totals <u>185 Cm</u>.

250 Cm Pipe - 185 Cm Cuts = 65 Cm Pipe Left

The function f(x) is shown in this graph. The function g(x)=-2x-6. Compare the slopes
stich3 [128]

Since f(x) = -3x + 2, the slope of f(x) is greater than the slope of g(x).

Hence, the answer is (D).
