5(y+25)=-13 i need help explaining

Answers

Answer:

y=-138/5=-27 3/5 = -27.6

Step-by-step explanation:

5(y+25)=−13

Divide both sides by 5.

y+25=-13/5

Subtract 25 from both sides.

y=-13/5−25

Convert 25 to fraction 125/5

y=-13/5-125/5

Since -13/5 and 125/5 have the same denominator, subtract them by subtracting their numerators.

y=-13 - 125/5

Subtract 125 from −13 to get −138.

y=-138/5

One end of a ramp is raised to the back of a truck 5 feet above the ground. 1 point
If the length of the ramp is 8 feet, what is the approximate measure of the
angle the ramp makes with the ground? Round your answer to the nearest
tenth of a degree.
38.7°
58.0°
32.0
51.3

Answers

Answer:

38.7°

Step-by-step explanation:

You are basically looking at a triangle with a 90° angle (check picture).

Since we are looking for the ramp's angle and are given the length of the opposite and the hypothenuse, we have to solve the following equation:

[tex]sin (\alpha) = opposite / hypothenuse= 5 ft/8ft[/tex]

which is equivalent to

[tex]\alpha = sin^{-1}(5/8)\approx 38.7\deg[/tex]

Answers

Answer:

L = 7 W= 12

Step-by-step explanation:

Ok so we already know that a rectangle is not even so the numbers will have to be 2 diff numbers.

The length is 5 feet less then width

w*l=  84

1* 84         2* 41        3*28    4*21    6*14    7*12

84-1           41-2        28-3     21-4     14-6   12-7

83              39           25          19        8         5

So,

your equation would be l*w = 7*12

x=47 because m1+m2=90°
The answer is C.
If measure of 1 + measure of 2 = 90
And measure of 1 = x
And measure of 2 = x - 4
You would have the equation of
X + X - 4 = 90
So then you combine like terms
2x - 4 = 90
Then you add 4 on both sides
2x - 4 = 90
+ 4 + 4
2x = 94
Then you divide by 2 to get x alone
And x = 47

If (y + 1) varies directly as square root of x and y =14 when x = 27, find the value of y when
x = 64 without finding the variation constant.​

Answers

Answer:

22.1 or 22

Step-by-step explanation:

Y + 1 varies√x

Y + 1 = K√x ( k is costant)

so we solve for K

given: 14 + 1 = K√27

15 = K√27

divide both sides by √27

15/√27 = K

to find the value of y

y + 1 = 15/√27 (8) : substitute K for 15/√27

Y + 1 = 120/√27

i.e Y = 120/√27 - 1

Y = 23.1 - 1

Y = 22.1 or 22

Imagine you are a financial analyst at an investment bank. According to your research of publicly-traded companies, 60% of the companies that increased their share price by more than 5% in the last three years replaced their CEOs during the period. At the same time, only 35% of the companies that did not increase their share price by more than 5% in the same period replaced their CEOs. Knowing that the probability that the stock prices grow by more than 5% is 4%, find the probability that the shares of a company that fires its CEO will increase by more than 5%.

Answers

Answer:

0.0667 = 6.67% probability that the shares of a company that fires its CEO will increase by more than 5%.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this problem:

Event A: Company fires the CEO

Event B: Shares increase by more than 5%.

Probability of a company firing it's CEO:

35% of 100 - 4 = 96%(shares did not increase by more than 5%).

60% of 4%(shared did increase by more than 5%).

So

[tex]P(A) = 0.35*0.96 + 0.6*0.04 = 0.36[/tex]

Intersection of events A and B:

Fires the CEO and shared increased by more than 5%, is 60% of 4%. So

[tex]P(A \cap B) = 0.6*0.04 = 0.024[/tex]

Probability that the shares of a company that fires its CEO will increase by more than 5%.

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.024}{0.36} = 0.0667[/tex]

0.0667 = 6.67% probability that the shares of a company that fires its CEO will increase by more than 5%.

Step-by-step explanation:

Just solving the two equations

y  - 4/3 x = 3  ..............................................(1)

the second equation

y = -2/3x -3

y + 2/3 x = -3  ..............................................(2)

by substracting 2 from 1

-4/3x - 2/3x = -6

divide by -1

4/3x +2/3x = 6

6/3x = 6

2x = 6

x= 3
