10^-10 in decimal form is 0.000000001. Because the exponent is negative, you move the decimal point ( decimal point is at the end of 0 of the base number 10) 10 place to the right of 10 and u get the answer above. I discarded the 0 later in the answer because now that you've moved the decimal, that 0 have no value. But when forming it in decimal you have to use that 0 or you will get a wrong answer, instead of eight 0's, you will end up with nine 0's.
Total units would be: 4+7 = 11
value of 1 unit = 44/11 = 4
Ratio would be: 4(4) & 7(4) = 16 & 28
Answer:
Distance between mall and library is 6.32 miles.
Step-by-step explanation:
Coordinates of the door to the library is at (2, 4) and door to the mall is at (8, 4).
Since, distance between two points
and
is given by,
Distance = 
By this formula,
Distance between (2, 4) and (8, 4) will be,
Distance = 
= 
= 
= 6.32 miles
The perimeter without the diagonal is 4*120 = 480
That covers the outside of the field
The diagonal is 120 *

= 169.7 yd
480 + 169.7 = 649.7 yd total of fencing
Answer:
100/27 yd^3
Step-by-step explanation:
2"= 1/18 yd
20'= 20/3 yd
30'= 10 yd
1/18*20/3*10= 100/27 cubic yards
