Answer: The height of the building is 50.75 feet.

Step-by-step explanation:

The ratio between the height of the object and the casted shadow must be equal for all the objects, as the angle at which the source if light impacts them is the same.

For the person, we know that it is 5.8ft tall, and the shadow is 3.2ft long.

The ratio will be: 5.8ft/3.2ft = 1.8125

Now, if H is the height of the building, and the shadow that the building casts is 28ft, we must have:

H/28ft = 1.8125

Now we can solve this for H.

H = 1.8125*28ft = 50.75 ft

Then the height of the building is 50.75 feet.

I would like to know what 0.5-0.125q=(q-1)/4 equals out to.

Scrat [10]

Answer:

q = 2

Step-by-step explanation:

0.5-0.125q=(q-1)/4

At first, we have to multiply both the sides by 4.

4 × (0.5 - 0.125q) = q - 1

or, 2 - 0.5q = q - 1

now, we change the side by taking constant into the right side and the number into the left side.

2 + 1 = q + 0.5q

or, 3 = q (1 + 0.5)

or, 3 = 1.5 q

or, 1.5 q = 3

or, $\frac{1.5q}{1.5}$ = (3 ÷ 1.5) [Dividing both the sides by 1.5]

or, q = 2

Therefore, q = 2

Given: If X, then Y. If Y, then Z. Y is true. So: X is unknown, Z is unknown X is unknown, Z is true X is false, Z is true X is

kumpel [21]

Answer:

Step-by-step explanation:

According to the given situation,

If X, then Y indicates y depends on X

If Y, then Z indicates Z depends on Y

As per the given situation, Y is true also Z will be true on the other hand there no solution about x b as y depends on X

Therefore as per the above explanation, the correct answer is B and hence the same is to be considered

the measure of one side of a square is (s+3) inches long. which pair of expressions both represent the perimeter of this square?

stich3 [128]

Answer:
perimeter = 4s + 12 inches
perimeter = 4(s+3) inches

Explanation:
We are given that the side length of the square is s+3 inches
In a square, all sides are equal. This means that all four sides are s+3 inches
Now, to get the perimeter, we would add all four sides as follows:
perimeter = s+3+s+3+s+3+s+3 = 4s + 12 inches
For a square, since all sides are equal, we can simply get the perimeter by multiplying the side length by 4 as follows:
perimeter = 4(s+3) inches

Hope this helps :)
