Answer:
12 feet
Step-by-step explanation:
Area of a Rectangle: l × w
84 ft² = l × 7 ft
Length = 84 ft² ÷ 7 ft = 12 feet
Hope this helps.
Answer:

Step-by-step explanation:

If degree of variable is one then eq. is linear
so given is linear.
See the picture attached to better understand the problem
we know that
in the right triangle ABC
sin 70°=opposite side angle 70°/hypotenuse
in this problem
opposite side angle 70°=AB
hypotenuse=AC----> 32 ft
sin 70°=AB/32------> AB=32*sin 70°-----> AB=30.07 ----> AB=30.1 ft
Susan can jump at most 104 in during the long jump
<h3>
Inequality</h3>
Inequality is an expression that show the non equal comparison of two or more variables and numbers.
From the table, the average result for females = 8ft 4in = (8 * 12)in + 4in = 100 in
Since Susan could jump no farther than 4 inches more than the average distance for females, hence:
j ≤ 4 + 100
j ≤ 104 in
Susan can jump at most 104 in during the long jump
