The figure shows a bridge support, a cable, and the roadway of a bridge. The bridge support is 80 feet tall. The length of a cable is 170 feet.

What is the distance, in feet, from the based of the bridge support to the point where the cable connects to the roadway?
Round to the nearest tenth.

soln,

feet × feet tall

170×80

13,600

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
