Answer:

Very tricky Question,

Step-by-step explanation:

-140=22(5y-2)

-140=44-5y

5y=140-44

5y=96

y=96/5

y=19.2

A town is designing a rectangular park that will be 600 feet wide by 1000 feet long. On a scale drawing, the dimensions of the p
KonstantinChe [14]

Scale drawing takes scaled versions of original lengths. The actual length of the swing set area of the park is 25 ft long and 100 ft wide

<h3>How are scale drawings formed?</h3>

For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.

Then it means

\rm 1\:  ft : \dfrac{s}{k}\:  in.

All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.

For the given case, it is given that

Real dimension of a rectangular park : 600 ft by 1000 ft

In drawing, it was of 12 inches by 20 inches.

Let the scale that the drawing is using be k feet to s inches, then

\rm 1\:  ft : \dfrac{s}{k}\:  in.

Since it is given that 600 ft : 12 inches and 1000 ft : 20 inches, thus, we get:

\rm 1\:  ft : \dfrac{s}{k}\:  in.\\\\600 \: ft = \dfrac{600\times s}{k} \: in. =  12 \: in.\\\\\dfrac{600 \times s}{k} = 12\\\\\dfrac{s}{k} = \dfrac{12}{600} = 0.02

Thus, every feet is reduced 0.02 times in drawing.

Now,

it is given that in drawing, the rectangular area for swing sets is 0.5 inch to 2 inch.

Let its real length was L and real width was W. Then we have:
\rm L \times 0.02 = 0.5 \\\\L = \dfrac{0.5}{0.02} = 25 \:\\\\W \times 0.02 = 2 \\W = \dfrac{2}{0.02} = 100

Since these are only magnitudes, and unit was converted from feet to inches, so we have L = 25 feet and W = 100 feet

Thus,

The actual length of the swing set area of the park is 25 ft long and 100 ft wide

Any help would be GREAT!!!
docker41 [41]
The answer is  B. 9

(g o f)(x) = g(f(x))

f(x) = x + 2
f(-5) = -5 + 2 = -3

g(x) = x²
(g o f)(-5) = g(f(-5)) = g(-3) = (-3)² = 9

Determine the length across the river, x to the nearest hundred ​
Ipatiy [6.2K]

Answer:

x=20.67\ ft

Step-by-step explanation:

we know that

The <u><em>Midpoint Theorem</em></u> says that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half of the third side

so

in this problem

Applying the midpoint theorem

x=\frac{124}{3}:2=\frac{124}{6}=\frac{62}{3}=20.67\ ft

Find the value of x. Round your answer to the nearest tenth.
natka813 [3]

That's a question about the Pythagorean Theorem.

We use the Pythagorean Theorem to find the value of one side in a right triangle.

This theorem says that:

\boxed{a^2 = b^2 + c^2}

  • <em>a</em> is the hypotenuse (It's the opposite side the right angle).
  • <em>b</em> and <em>c </em>are cathetus (They're the adjacent sides the right angle).

Okay, now, let's go to solve this problem! In our figure, we have two cathetus. Their values are 10 and 7 and we have to find the value of <em>x </em>(the hypotenuse). Let's change this information in that formula.

a^2 = b^2 + c^2\\x^2 = 10^2 + 7^2\\x^2 = 100 + 49\\x^2 = 149\\x = \sqrt{149}

Therefore, the value of <em>x </em>is \sqrt{149}.

I hope I've helped. :D

Enjoy your studies! \o/
