32. Solve the equation below.
12-13
= 17

Answers

Answer 1
12-13
12-13=-1
Therefore the equation is false.
Answer 2

Answer:

x = 2.5

Step-by-step explanation:

12x - 13 = 17

12x = 17 + 13

12x = 30 (divide both sides by 12 to get x)

12x/12 = 30/12

x = 2.5

Jasmine took out a college loan of $55,000.00 for college for 10 years. The interest rate
is 4 7%. What will the total cost of the loan be for 10 years?

Answers

Answer:

57,585

Step-by-step explanation:

55,000.x4.7%=2585.

55000.+2585=57,585

Answer:

$57,337.50

Step-by-step explanation:

In order to get the answer we would have to add 55, 000 and 4 [tex]\frac{1}{4}[/tex]% of 55,000 (because of the interest rate). In order to find 4 [tex]\frac{1}{4}[/tex] % we would have to multiply 55, 000 by 0,0425. So now we get the following.

Total cost of the loan = 55,000 + 55,000 x 0.0425 = 55,000 + 2,337.5 =

57,337.5

A city has a vacant lot in the shape of an isosceles trapezoid and the city workers are installing a fence around the lot. What length of fencing is required? Round the answer to the nearest meter. А 25 m B x 25 m 45° The length of fencing required is meters.​

Answers

Answer:

Length of the fence required = 135 m

Step-by-step explanation:

Total length of the fence required to cover the vacant lot = Perimeter of the isosceles trapezoid

Perimeter of ABCD = AB + BC + CD + AD

Since, AB = BC = EF = ED = 25 m

From the given right triangle BEC,

m∠EBC = m∠ECB = 45°

ΔBEC will be an isosceles triangle.

So, BE = EC

By Pythagoras theorem,

BC² = BE² + EC²

25² = 2(EC)²

EC = [tex]\frac{25}{\sqrt{2}} =17.7[/tex] m

And DC = (DF + EF + EC)

             = EC + EF + EC [Since, DF = EC]

             = 2EC + EF

             = 35.4 + 25

             = 60.4 m                            

Hence. perimeter of ABCD = 25 + 25 + 60.4 + 25

                                              = 135.4 m

                                              ≈ 135 m

Therefore, length of the fence required = 132 m

Write an equation of the line that passes through (1, 2) and is perpendicular to the line y=13x+4.

Answers

Answer:

Step-by-step explanation:

y=-1/13x   since it is perpendicular flip it and make it negative

Answer:

y = -1/13x + 27/13

Step-by-step explanation:

A perpendicular line will have the opposite reciprocal and sign.

So the perpendicular line slope to y = 13x + 4 would be -1/13

NOW PLUG IN (1, 2) TO GET THE Y- INTERCEPT

2 = -1/13(1) + b (b represents the y- intercept)

2 = -1/13 + b (add 1/13 to both sides)

y = -1/13x + 27/13 is the perpendicular line.

Answers

Answer:

25/3

Step-by-step explanation:

Set the equations equal to each other since the lines are parallel.

(x+20)=(4x-5)

-x  +5       -x   +5

25/3 = 3x/3

x = 25/3

Since these equations are consecutive interior angles, they will add up to 180.
The equation will be (x+20)°+(4x-5)°=180.

(x+20)+(4x-5)=180
5x+15=180
5x=165
165/5x
=33°

You can make sure your answer is correct by putting your x back into the equation.

What is the rate of change of e=3h+200

Answers

Answer:

3

Step-by-step explanation:

"Rate of change" is the real-world problem way of saying "slope."

So whenever a question asks you to find "rate of change", simply look for the slope.

y = mx + b

e = 3h + 200

mx = slope/rate of change

So, 3 would be your answer.

the answer for this is B 9

Answer:

B

Step-by-step explanation:

Consecutive angles are supplementary, thus

30 + 5x + 15 + 10x = 180 , that is

15x + 45 = 180 ( subtract 45 from both sides )

15x = 135 ( divide both sides by 15 )

x = 9 → B
