PLEASE HELP ASAP!!!

Answer:

20. AB = 42

21. BC = 28

22. AC = 70

23. BC = 20.4

24. FH = 48

25. DE = 10, EF = 10, DF = 20

Step-by-step explanation:

✍️Given:

AB = 2x + 7

BC = 28

AC = 4x,

20. Assuming B is between A and C, thus:

AB + BC = AC (Segment Addition Postulate)

2x + 7 + 28 = 4x (substitution)

Collect like terms

2x + 35 = 4x

35 = 4x - 2x

35 = 2x

Divide both side by 2

17.5 = x

AB = 2x + 7

Plug in the value of x

AB = 2(17.5) + 7 = 42

21. BC = 28 (given)

22. AC = 4x

Plug in the value of x

AC = 4(17.5) = 70

✍️Given:

AC = 35 and AB = 14.6.

Assuming B is between A and C, thus:

23. AB + BC = AC (Segment Addition Postulate)

14.6 + BC = 35 (Substitution)

Subtract 14.6 from each side

BC = 35 - 14.6

BC = 20.4

24. FH = 7x + 6

FG = 4x

GH = 24

FG + GH = FH (Segment Addition Postulate)

[tex] 4x + 24 = 7x + 6 [/tex] (substitution)

Collect like terms

[tex] 4x - 7x = -24 + 6 [/tex]

[tex] -3x = - 18 [/tex]

Divide both sides by -3

[tex] x = 6 [/tex]

FH = 7x + 6

Plug in the value of x

FH = 7(6) + 6 = 48

25. DE = 5x, EF = 3x + 4

Given that E bisects DF, therefore,

DE = EF

5x = 3x + 4 (substitution)

Subtract 3x from each side

5x - 3x = 4

2x = 4

Divide both sides by 2

x = 2

DE = 5x

Plug in the value of x

DE = 5(2) = 10

EF = 3x + 4

Plug in the value of x

EF = 3(2) + 4 = 10

DF = DE + EF

DE = 10 + 10 (substitution)

DE = 20

Given:

4 is a root of f(x).

To find:

A factor of f(x).

Solution:

We know that, if c is a root of a function f(x), then (x-c) is a factor of f(x).

In the given problem, 4 is a root of f(x).

So, we have c=4.

By using the above property we can say that, (x-4) is a factor of function f(x).

Since, (x-4) is a factor of function f(x), therefore, the correct option is C.

Answer: The attached image (Graph 4) is the correct graph.

Step-by-step explanation:

1. Find the graph with the point (0, -3), the y-intercept. This eliminates all but two graphs.

2. Out of the two graphs you have narrowed down the options to, choose the graph with the positive slope (slope of 1). Since graph 3 has a negative slope amd graph 4 has a positive slope and still satisfies the correct intercept, the 4th graph is the correct option.

Answer: M (slope) = -1 / -3 = 0.3

Step-by-step explanation:

Answer:

1/3

Step-by-step explanation:

Slope=y1-y2/x1-x2

Where (X1,y1) is (10, 5) and (X2,y2) is (7, 4).

So

Slope= 5-4/10-7

= 1/3

So slope is 1/3

Answer:

Dollars earned after 5 years = $45.79

Step-by-step explanation:

Given that:

Initial money deposited in account = $75

Time for which the money is deposited = 5 years

Interest rate = 10%

Nature of interest = Simple Interest

Amount after 5 years = $112.50

To find:

Total money earned after 5 years if the interest is compounded ?

Solution:

Formula for amount if the interest is compounded annually:

[tex]A =P(1+\frac{R}{100})^T[/tex]

Where P is the principal amount (initial money)

R is the rate of interest

T is the time

Putting all the values:

[tex]A =75\times (1+\frac{10}{100})^5\\\Rightarrow \bold{A = \$120.79}[/tex]

Total more money earned or the interest after the compounding nature =

[tex]A - P[/tex] = $120.79 - $75 = $45.79

Answer:

Step-by-step explanation:

Step one:

given

we are told that the distance is 3.25cm on the map

the scale is 1cm to represent 20km

Required

the actual distance

Step two

if 1cm represent 20km

then 3.25cm will represent x km

cross multiply we have

x=2.35*20

x= 65km

Hence,  the actual distance between these two cities in kilometers  65km

Answer:

false

Step-by-step explanation:

This statement is false. There are a total of 6 sides on a six-sided die therefore, every roll is a one in six chance of getting a single number since only one number can be obtained per roll. So that would mean that the probability is

[tex]\frac{1}{6}[/tex]   or 0.16666 or 16.66%

That would be the actual probability of rolling a 1 on a single roll of a six-sided die, not 0.85

Answer:

Barb would save $10.93 in 2 months if she only got two month plan instead of two one month plans.

Step-by-step explanation:

First, you need to determine the amount that Barb will pay with the one month service plan in 2 months:

$39.95*2= $79.9

Now, you need to calculate the difference between both plans:

$79.9-$68.97=$10.93

According to this, the answer is that Barb would save $10.93 in 2 months if she only got two month plan instead of two one month plans.

Answer:

The ending balance is $36.

Step-by-step explanation:

With the information given, in order to find the ending balance, you have to take the starting bank account balance and add the three checks that is money you receive and subtract the two bills that is money you need to pay and comes out of your account:

25+(3*5)-(2*2)=25+15-4=36

According to this, the answer is that the ending balance is $36.

Answer:

18

Step-by-step explanation:

30x60=1800

1800/100=18

Answer:

18

Step-by-step explanation:

30% of 60 is the same thing as 30/100=x/60

After that, we cross multiply which gets us with 100x=1800

We divide and get x=18

So the right number choice is C. 18

Answer: 10 $5 bills, and 25 $10 bills.

Step-by-step explanation:

Let's define the variables:

F = number of $5 bills.

T = number of $10 bills.

We know that he wants to make $300 in total, then we have:

F*$5 + T*$10 = $300

And we also know that in total there are 35 bills, then:

F + T  = 35.

So we have the system of equations:

F*$5 + T*$10 = $300

F + T  = 35

To solve this, the first step is isolate one of the variables in one of the equations, i will isolate F in the second equation to get:

F = 35 - T

Now we can replace that in the other equation, and get:

(35 - T)*$5 + T*$10 = $300

Now we can solve this equation for T.

$175 - T*$5 + T*$10 = $300

T*$5 = $300 - $175 = $125

T =  $125/$5 = 25

and:

F = 35 - T = 35 - 25 = 10

Then he has:

10 $5 bills, and 25 $10 bills.

It can be said that the "there is a negative correlation in the data set". Option B is correct.

The graph shows points that are grouped together and are decreasing.

The gathered data shows that there is a possibility to get  correlation between them.

The group of data is decreasing. So, the correlation of the data will be negative in nature.

Therefore, it can be said that the "there is a negative correlation in the data set". Option B is correct.
