to find the slope for the first one, use the formula \frac{y2-y1}{x2-x1}

(It's the slope formula)

so... 3=y2, 3=y1, 2=x2, 10=x1

then plug in... \frac{3-3}{2-10} =\frac{0}{-8} = 0

this line has a slope of 0


As for the miles problem, to find mph, the miles have to be at 1.

so... 4x=242\\x=60.5

therefore, he drove 60.5 mph

telo118 [61]
Alright, so since I don't have an example question, I will make one up. 

there are 8 coins in total. there are 6 dimes. What is the fraction of dimes to coins. 

you would put the amount of dimes on the top and the total on the bottom.

Answer: 6/8 which can be simplified to 3/4

Or another Example:

There are 12 pieces in the pizza. Billy took 4. what is the fraction of the slices left.

it would be 4-12= 8

Answer: 8/12 which can be simplified to 4/6 and then to 2/3

Hope that helped.

Round to the nearest tenth wa hit is the perimeter of the triangle
klio [65]

Answer:

D. 11.8 cm

Step-by-step explanation:

This triangle is a 30°-60°-90° triangle. There is a shortcut to find the lengths of the sides of a 30°-60°-90° triangle. The longest side is the hypotenuse. The longest side is double the shortest side or, the shortest side is half the longest side. Here the longest side is 5, so the short leg (shortest side) is 2.5

The other shortcut is that the longer leg is the

short leg×sqroot3

Here, the short leg is 2.5, so the long leg is 2.5×sqroot3

Perimeter is all the sides added together.

5 + 2.5+ 2.5×sqrt3

Do the times first.

5 + 2.5 + 4.3

= 11.8
