1) A speed walker covered 4 1/2 mi in 3/4 hour. How far will he walk with the same pace in 2 hours? 3 hours? 3.5 hours?

Savatey [412]

You can solve this with proportion

1) For 2h

9/2 mile : 3/4h = x mile : 2h => (3/4)x=(9/2)*2 => (3/4)x=9 => x=9*(4/3)= 12miles

For 3h => (3/4)x=(9/2)*3 When we divide equation with 3 we get

x/4=9/2 => x=(9/2)*4=18 miles

2) 2 combine : 320 acres = 7 combines : x acres +: 2x= 320*7 =>

x= (320*7)/2 = 160 * 7 = 1120 acres

Good luck!!!

Q: THE PERPENDICULAR SIDES OF A RIGHT ANGLED TRAINGLE ARE 12 AND 15 CENTIMETERS LONG. ANOTHER RIGHT ANGLED TRAINGLE OF THE SAME

garri49 [273]

Area of a right triangle is 1/2 x height x base

The area of the first triangle is 1/2 x 12 x 15 = 90 square cm.

The area of the other triangle is 90 and one side is 18:

90 = 1/2 x 18 x S

Multiply both sides by 2:

180 = 18 x S

Divide both sides by 18:

S = 180/18

S = 10

The length of the other side is 10 centimeters
