Let
x-------------> <span>the length of a rectangle
y-------------> the </span>width of a rectangle
we know that
x+y=130-----------> equation 1
and
x=1.6y--------------> equation 2
<span>I substitute 2 in 1
(1.6y)+y=130-------------> 2.6y=130------------> y=130/2.6------> y=50 ft
x=1.6y--------> x=1.6*50---------> x=80 ft
the answer is
</span>the length is 80 ft
the width is 50ft
In the question, it is already given that the total number of runners in the race is 60 and out of them 1/3 dropped out in the first half. In the second half 1/4 of the remaining runners dropped out.
Now
Total number of runners in the race = 60
Number of runners that dropped out in the first half = 1/3 * 60
= 20
Number of runners remaining = 60 - 20
= 40
Number of runners dropping out in the second half = 40 * 1/4
= 10
Then the number of runners that finished the race = 40 - 10
= 30
Then 30 runners completed the race.
Answer:
Step-by-step explanation:
Im pretty sure this 3d object is a prism but the formula for it should be V=B(base area) x h(height) so V= 120 x 10 = 1200in^3
Is there more information
Answer:
Step-by-step explanation:
1st side X-17
2nd side X
3rd side X-6
(X-17)+(X)+(X-6) = 49
-17-6 = -23
X+X+X-23 = 49
3X-23 = 49
3X-23+23 = 49 + 23
3X = 72
3x/3 = 72/3
x = 24
Now plug it in
(24-17)+24+(24-6) = 49
7+24+18 = 49
