Answer:
39 inches.
858 inches²
Step-by-step explanation:
Length:- (if length = x)
2 ( 11 + x ) = 100
22 + 2x = 100
2x = 100 - 22
2x = 78
x = 78 ÷ 2
x = 39 inches
Area:-
Area = l × b
= 39 × 22
= 858 inches²
Let's get all of the distances lined up:
= home to office
to a restaurant
back to the office
= store
= back home
So then we just add up all of the numbers. However we need to make sure that there is a common denominator. Let's make the common denominator 12, since that is a common factor to all of the denominators in the problem:
= home to office
to a restaurant
back to the office
= store
= back home
Then let's add them up:
This does not reduce to a nice number, however, we can simplify to:
Area of a trap.= 1/2(base1+base2)x height
A=1/2(13+17) x 11
A=1/2(30) x 11
A=15 x 11
A=165 meter squared
Answer:
(3) 11
Step-by-step explanation:
A line perpendicular to one with a slope of -2 will have the opposite reciprocal slope: -1/(-2) = 1/2.
The point-slope equation of the line through (3, 9) with slope 1/2 is ...
y -9 = 1/2(x -3)
Then for point (7, k) on the line we have ...
k -9 = 1/2(7 -3)
k = 9 +2 = 11
The value of k is 11.
