Answer: [tex]y=-2x+5[/tex]

Step-by-step explanation:

First, we can take what we are given

The slope goes right 2 and down 1

The Y-intercept is (0,5)

Slope intercept form is: [tex]y=mx+b[/tex]

m is the slope

b is the y-intercept

y=-2x+5

Answer:

2352071 ft ^3

Step-by-step explanation:

formula for volume of a sphere is

V= 4/3 * [tex]\pi[/tex] * r ^3

V = 4/3 * [tex]\pi[/tex] * 82.5 ^3 = 2352071 ft ^3

Answer:

3

Step-by-step explanation:

[tex]x {}^{2} + x {}^{2} = (3 \sqrt{2} ) {}^{2} = 18[/tex]

[tex]2x {}^{2} = 18[/tex]

[tex]x = 3[/tex]

The value of x is 3 in the triangle.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

By pythagoras theorem we find the value of x.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides

x²+x²=(3√2)²

2x²=9×2

2x²=18

Divide both sides by 2

x²=9

Take square root on both sides

x=3

Hence, the value of x is 3 in the triangle.

Answer:

The elavator can handle 950 more pounds.

Step-by-step explanation:

Since the elevator can handle 2,000 lb, and there is currently 1,050 lb on it, you have to subtract the weight that the elevator can handle from the weight that's already on it. So in other words, do 2000 - 1050.

Answer:

It is 15/20 - 8/20

Step-by-step explanation:

You have to make both denominators the same by multiplying it by 5 with would be 20 then you multiply the numerators by 5 also then you will have your answer.

Hope that explained it!

Answer:

[tex]\frac{15}{20} - \frac{8}{20}[/tex]

Because 15/20 have the same factor which is 5, so when you divide them both by 5 they will give you 3/4

same for 8/20 when you divide each number by 4 it will give you 2/5

Answer:

Step-by-step explanation:

Sin(42) = n/21

n = 21 * sin(42)

n = 21 *  0.6691

n = 14.052

Cos(42) = m / 21

21 * cos(42) = m

m = 21 * 0.7431

m = 15,61

Theta + 42 = 90

Theta = 90 - 42

Theta = 48

Answer:

1) 20 cm

2) 22.4 in

3) 15 ft

Step-by-step explanation:

For this question, you have to use the Pythagorean theorem.

Why?

Well, because it is a right triangle and you have 2 sides given and you want to find the third side.

Now let's solve this problem!

For number 1 we have:

a = 16 cm and B = 12 cm

you need to find the 3rd side which is c (aka the hypothenuse)

so let's write the equation:

a^2 + b^2 = c^2

Then we substitute with what we have given.

16^2 + 12^2 = c^2

Using a calculator solve the equation

400 = c^2

Now we have to find the square root from both sides of the equation.

c = 20 cm (That's the final answer)

For number 2 we have:

a = 10 in and b = 20 in

we follow the same steps as in number 1

a^2 + b^2 = c^2

10^2 + 20^2 = c^2

500 = c^2

c = 22.4 in (That's the final answer)

For number 3 we have:

a = 9 ft and b = 12 ft

a^2 + b^2 = c^2

9^2 + 12^2 = c^2

225 = c^2

c = 15 ft (That's the final answer)

Step-by-step explanation:

Answer:

is it from a text book

Step-by-step explanation:

Let L = length, W = width and P =Perimeter

L = 3W

and

P + 2(L + W) = 120

L + W = 60

Substitute

3W + W = 60

4W=60

W=60/4

W=15

L+W=60

L+15=60

L=60-15

L=45
