Answer:

Shown in explanation.

Step-by-step explanation:

These type of problems requires the knowledge of Pythagorean Theorem

Pythagorean Theorem: A^2(shorter side 1)+B^2(shorter side 2)=C^2(Longest side also known as hypotenuse)

So, you would just need to know the square roots of the square.

Triangle 1. First square: \sqrt{36}=6 So side length of first one is 6 yd.

Second square: \sqrt{18}=4.24 So side length of second square is 4.24 yd.

Third square: 36-18=18 So the side length is the same as the second square which is 4.24 yd.

Triangle 2. Repeat the process for all of these problems.

First square: \sqrt{125}=about 11.18.

Second square: \sqrt{100}=10.

Third square: 125-100=25. So, \sqrt{25}=5.

Triangle 3. This is an isosceles triangle meaning 2 sides are the same length.

First and Second square are the same. \sqrt{32}=5.66.

Third square=32+32=64. So, \sqrt{64}=8.

You need a 90% alcohol solution. On hand, you have a 55 mL of a 45% alcohol mixture. You also have 95% alcohol mixture. How much
Molodets [167]

Answer:

495 milliliters of the 95% mixture are needed.

Step-by-step explanation:

Given that I need a 90% alcohol solution, and on hand I have a 55 ml of a 45% alcohol mixture, and I also have 95% alcohol mixture, to determine how much of the 95% mixture will I need to add to obtain the desired solution, the following calculation must be performed:

55 x 0.45 + 45 x 0.95 = 67.5

25 x 0.45 + 75 x 0.95 = 82.5

15 x 0.45 + 85 x 0.95 = 87.5

10 x 0.45 + 90 x 0.95 = 90

10 = 55

90 = X

90 x 55/10 = X

4,950 / 10 = X

495 = X

Thus, 495 milliliters of the 95% mixture are needed.

What is the rate of change
Elza [17]

Answer:

The rate of change is 1

Step-by-step explanation:

In order to calculate the rate of change, take two points (in this example I'll use points (8, 2) and (10, 4)) and input them into this expression used to calculate rate of change: \frac{y2-y1}{x2-x1}

\frac{4-2}{10-8}

Solve:

4 - 2 = 2

10 - 8 = 2

2/2 = 1

The rate of change is 1.

Hope this helps :)

If ED = 5y + 6 and DB = y + 30, find the value of y. Then find ED, DB, and EB.
Gemiola [76]

Answer:

Part 1) The value of y=6

Part 2) ED=36, DB=36 and EB=72

Step-by-step explanation:

In this problem we know that

ED=DB -----> equation A

EB=ED+DB -----> equation B

The point D is the midpoint ED

see the attached figure to better understand the problem

step 1

Find the value of y

Substitute the given values in the equation A

5y+6=y+30

solve for y

5y-y=30-6

4y=24

y=6

step 2

Find the value of ED,DB and EB

ED=5y+6

substitute the value of y

ED=5(6)+6=36

Remember that

ED=DB

therefore

DB=36

Find the value of EB

EB=ED+DB

EB=36+36=72
