Answer:

8.3 meters

Step-by-step explanation:

A rectangle's area is solved by multiplying length x height.

The area is 58.1 square meters, while the height is 7 meters. Divide:

58.1/7 = 8.3

8.3 meters is the length of the rectangle.

Suppose you spent $38.25 for 3 shirts that each cost the same amount. If the cost of the shirts varies directly with the number

Inessa [10]

$38.25 divided by 3 = $12.75

If log 6=a, then log 600= ?

tekilochka [14]

$\log 600 = \log (100 \cdot 6)= \log 100 + \log 6 = \log 10^2 + \log 6 = \\ 2 \log 10 +\log 6 =2+\log 6 = \boxed{a+2} \\ \hbox{From formulas:} \\ \log a + \log b = \log (ab) \\ \log a^b = b\log a$

The perimeter of a rectangle is 140 and the length is 10 more than four times the width. find the dimensions

aalyn [17]

Answer:

Width = 12

Length = 58

Step-by-step explanation:

Width = x

Length = 4x + 10

Perimeter = 140

2 * ( length + width ) = 140

2 * (4x +10 + x) = 140

5x + 10 = 140/2 = 70

5x = 70- 10

5x = 60

x = 60/5 = 12

Width = 12

Length = 4 * 12 + 10 = 48 +10 = 58

Find the height of the basketball hoop to the nearest foot.

Kisachek [45]

Answer:

12 ft

Step-by-step explanation:

Hi there!

<u>1) Find the length of the other leg in the right triangle</u>

There are two ways we can go about this. The first way is to use trigonomic ratios:

We're given one of the legs and we're trying to solve for the other, so we can use the tangent ratio:

$tan\theta=\frac{opp}{adj}$

Let x be equal to the length of the other leg. Plug in the known values:

$tan45=\frac{x}{7}\\7*tan45=x\\x=7$

The other way to find this is to observe the angles. Because we're given that two of the angles are 45 and 90 degrees, we know that the third angle is 45 degrees. This makes this an isosceles triangle, meaning the other leg is 7 ft long.

<u>2) Determine the height of the hoop</u>

Add 7 ft and 5 ft (the person's height):

7+5=12 ft

I hope this helps!
