Step-by-step explanation:

Find the slope. Use m = y2-y1/x2-x1 form

So, -4-(-17)/-6-(-6)

This = 13/0

Answers

Answer: 74.6

we draw a right triangle ABC, have: ∠ABC = 90°,  AB = 20 and ∠BAC = 75°, the height of the building is BC

we also have: tan 75° = BC/AB = BC/20

=> BC = tan 75°. 20 = 40 + 20√3 ≈ 74.6

Twice Sam's age added to half her mother's age is 48. Three times her age less one third of her
mother's age is 33. How old are Sam and her mother?

Answers

Answer:

Sam is 15 and her mother is 36

Step-by-step explanation:

Let Sam's age be x and her mother's age by y

We can figure out Sam and her mother's age by representing these scenarios using equations with variables and solving the system using elimination

2x+y/2=48

3x-1/3y=33

You start by making all the numbers in both the equations whole

2(2x+y/2=48)

3(3x-1/3y=33)

Becomes:

4x+y=96

9x-y=99

Add together to eliminate y

13x/13=195/13

x=15

Now that we have x we can plug the value into the x in the equations to give us the y-value

2x15+y/2=48

30+y/2=48

30+y/2-30=48-30

y/2=18

2 X y/2=18 X 2

y=36

Therefore x=15 and y=36

Find the solution of the system of equations.

First equation,

- 2x - 5y = -15

Second equation,

-9x + 15y = -30

A square garden has an area of 53.29 square meters. What is the length of each side of the garden?

1) 3.8m
2) 7.3m
3) 13.3m
4) 26.6m

Answers

The answer is 3) 13.3m

Answer:

7.3m

Step-by-step explanation:

Area is l * w

The length and width of a square are the same, so that means we can use square root for this problem.

The square root of 53.29 is 7.3

7.3*7.3 = 53.29 (<- to double check)

Answers

Answer:

y=2x-5

Step-by-step explanation:

slope intercept form is y=mx+b

m=slope

b=y-intercept

Answer: y = 2x - 5

slope-intercept form ⇒ y = mx + b

⇒ where mx is the slope,

⇒ b is the y-intercept

⇒According to the question;

mx which is the slope = 2

b the y-intercept = -5

the lenght of the floor is 32 m longer than its width and there is greater than 200 square meters. you will cover the floor completely with tiles. what will be the possible dimension of the floor?

Answers

Let’s assume the width of the floor is x and the area is a

To figure out the dimensions we need to figure out the value of the variable (x)

This means that the length is xm+32m (the m is for metres) and that the area is a>200m2

Because it says what is the possible dimensions let make the area 201m2

The formula for the area of a rectangle is length times width so the equation we use to figure out the value of x


201=x+x+32

So let’s collect like terms and solve from there
201=2x+32
201-32=2x+32-32
169=2x
169/2=2x/2
84.5=x

Now that we know the value of x is 84.5 we can figure out the length is 116.5m and the width is 84.5m

Therefore the dimensions of the floor is 116.5m by 84.5m
