Hiiii please help ASAP I really need this :)))) please I’m praying somebody helps and gives a correct answer

Sauron [17]

Answer:

1.25

Step-by-step explanation:

100 divided by 4 = 25

60 divided by 4 = 15

30 divided by 4 = 7.5

5 divided by 4 = 1.25

Frank is having a raised rectangular platform built. He designed it so that the length of the platform is 4 feet longer than the

Anastaziya [24]

One system of equations would be
L = w+4
H = w-10
4H + 8(wL) = 1544
There is one viable solution; the width is 12, the length is 16, and the height is 2.

Using substitution with the system of equations, we have
4(w-10)+8(w(w+4))=1544
4w-40+8(w²+4w)=1544
4w-40+8w²+32w=1544

Combining like terms, we have
8w²+36w-40=1544

Factoring out a 4, we have
4(2w²+9w-10)=1544

Dividing both sides by 4 gives us
2w²+9w-10=386

Subtract 386 from both sides to get
2w²+9w-396=0

Using the quadratic formula, we have
$w=\frac{-9\pm \sqrt{9^2-4(2)(-396)}}{2(2)}
\\
\\=\frac{-9\pm \sqrt{81--3168}}{4}
\\
\\=\frac{-9\pm \sqrt{3249}}{4}=\frac{-9\pm 57}{4}
\\
\\=\frac{-9+57}{4}\text{ or }\frac{-9-57}{4}=\frac{48}{4}\text{ or }\frac{-66}{4}
\\
\\=12\text{ or }-16.5$

Since a negative width makes no sense, we know that w=12.

This means L=w+4=12+4=16 and H=w-10=12-10=2

What is the solution of the equation? 4(y + 2) =32

ehidna [41]

Hey there!
For the left side, we are going to use the distributive property, which means:
a(b+c) = ab+ac
Therefore, we have:

4y + 8 = 32

Subtract 8 from both sides.

4y = 24

Divide both sides by 4 to get:

y = 6

I hope this helped you! :)

n 1895, the first Putting Green Championship was held. The winner’s prize money was $200. In 2016, the winner’s check was $1,480

Amanda [17]

Answer:

7.64% per year
$10,805,480 . . . . rounded to 7 significant figures

Step-by-step explanation:

Using 2016 as a reference (t=0), the exponential equation for winnings can be written as ...

w(t) = 1480000×(1480000/200)^(t/121)

where 1480000 is the winnings in the reference year, and the ratio 1480000/200 is the ratio of winnings increase over the 121 years from 1895 to 2016.

This can be approximated by ...

w(t) ≈ 1,480,000×1.07640850764^t

In this form, we can see that the annual percentage increase is ...

1.0764 -1 = 7.64%

__

Then the winner's check in 2043, 27 years after 2016, is predicted to be ...

w(27) = $1,480,000×(1.0764...)^27 ≈ $10,805,478.41 ≈ $10,805,000
