PLEASE HELP ME LIKE IM GOING TO CRY ILL give you brainliest if the answer is correct and 20/40 points..............Ben participated in a race. During the first half of the race, he walked 3 miles and ran at a rate of 5 miles per hour for x hours. During the second half of the race, he walked for 2 miles and ran at a rate of 5.5 miles per hour for x hours. What equation could you write to solve for the number of hours Ben ran during each half of the race? Let y represent the number of miles in half the race. Write two equations, one for the first half of the race and one for the second half. How could you transform these two equations to be the same as the original equation you wrote to solve for x? What do you think this means about solving for the variables in a situation represented by two equations?

Answer:

Explanation:

Every x-value matches to exactly one y-value, which is the definition of a function.

Answer:

Only plot B

Step-by-step explanation:

Answer:

Only Plot B

Step-by-step explanation:

The points in plot A are randomly scattered, and there is no recognizable pattern. So, this plot indicates no correlation between the points Tyler scored and the points Nolan scored.

In plot B, the total points Tyler’s team scored appear to increase as the points Tyler scored increase. This pattern indicates a positive correlation between the two variables.

So, only plot B indicates a positive correlation.

h= 14

Step-by-step explanation:

7h-5(3h-8)= -72  PEDMAS Parenthesis first

7h-15h+40= -72 combine like terms

-8h+40= -72  subtract 40 from both sides

-8h=-112  divide by -8

h=14

The required simplified solution of the given expression is h = 4.

Given that,
A number of instruction has been added in the question, guiding the solution of the given expression.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given expression,
7h-5(3h-8) = -72

Simplify,
7h -5×3h - 5× -8 = -72
7h -15h + 40 = -72
8h = -72 + 40
-8h = -32
h = 4

Thus, the required simplified solution of the given expression is h = 4.

Answer:

There is no equation that you can write for that because the slope is undefined becasue 0 is in the denominator

Step-by-step explanation:

9514 1404 393

Answer:

  4x +5y = 25

Step-by-step explanation:

One way to write the equation is ...

  (y2 -y1)x -(x2 -x1)y = (y2 -y1)(x1) -(x2 -x1)(y1)

  (1 -5)x -(5 -0)y = (1 -5)0 -(5 -0)5

  -4x -5y = -25 . . . . . has a leading minus sign, so we want to multiply by -1

  4x +5y = 25 . . . . standard form equation of the line

__

Another way to write the equation is ...

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (1 -5)/(5 -0)(x -0) +5

  y = -4/5x +5 . . . . slope-intercept form of the equation of the line

Answer: 47 degrees

Step-by-step explanation:

The measure of an angle BOC from the given figure is 47°.

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

Given that, m∠AOC is a straight angle, m∠BOC=6x+29° and m∠AOB=3x+124°.

We know that, a straight angle measures 180°.

Now, m∠BOC+m∠AOB=m∠AOC

6x+29°+3x+124°=180°

9x+153°=180°

9x=27°

x=3°

So, m∠BOC=6x+29°

=6×3+29°

= 47°

Therefore, the measure of angle BOC is 47°.

Part b and c are missing and they are;

b. What is the probability that the individual owns shares in a bond fund? c. What is the probability that the selected individual does not own shares in a stock fund?

Answer:

A) P(balanced fund) = 0.23

B) P(bond fund) = 0.27

C) P(no stock fund) = 0.75

Step-by-step explanation:

We are given the percentages of customers in the different funds as follows:

Money-market: 25%

High-risk stock: 10%

Moderate-risk stock: 15%

Short bond: 12%

Intermediate bond: 7%

Long bond: 8%

Balanced: 23%

A) From the percentages given, we can see that the balanced fund is 23%.

Thus,this represents the probability as addition of all the given percentages gives 100%

Thus, probability that the selected individual owns shares in the balanced fund is;

P(balanced fund) = 23% = 0.23

B) From the percentages given, bond funds given are;

Short bond: 12%

Intermediate bond: 7%

Long bond: 8%

Thus,

probability that the individual owns shares in a bond fund is;

P(bond fund) = 12% + 7% + 8%

P(bond fund) = 27% = 0.27

C) Probability that the selected individual doesn't own shares in a stock fund is;

P(no stock fund) = 1 - P(stuck fund)

P(stuck fund) = High-risk stock +

Moderate-risk stock = 10% + 15% = 25% = 0.25

Thus;

P(no stock fund) = 1 - 0.25 = 0.75

So the answer is 40

Hope this helps :)

Answer:

5m when m = 8 is 40

Step-by-step explanation:

When you substitute (replace) m with 8, it becomes 5(8).

5(8) means 5 multiplied by 8, which gives you 40.

Given :

Vanessa bought a 30 pound bag of rice she cooked 7.5 pounds of the rice she stores the rest of the rice in 4.5 pound portions.

To Find :

The maximum number of portions she stored.

Solution :

Let, number of portions she stored is n.

Amount of rice left, A = 30 - 7.5 = 22.5 pounds.

Now, number of portions of 4.5 pounds she stored :

[tex]n = \dfrac{22.5}{4.5}\\\\n = 5[/tex]

Therefore, maximum number of portions she stored is 5.

Hence, this is the required solution.

Answer:

Mr. Thompson's account be worth $9,562.50 after 10 years

Step-by-step explanation:

Simple Interest

Interest is calculated on the original principal only of a loan or on the balance of an account.

Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.

The interest earned is calculated as follows:

I=P.r.t

Where:

I = Interest

P = initial principal balance

r = interest rate

t = time

Mr. Thompson plans to invest P=7,500 in a savings account that earns r=2.75% = 0.0275.

The interest earned in t=10 years is calculated now:

I=7,500*0.0275*10

I=2,062.50

Now we add the interest to the principal:

A = $7,500 + $2,062.50

A = $9,562.50

Mr. Thompson's account be worth $9,562.50 after 10 years

Answer:

Your slope would be 3.

Step-by-step explanation:

To find the slope from two points, you would need to use the formula: y2-y1/x2-x1

In this case, the equation would look like -2-7/5-8.

-2 - 7 = -9

5 - 8 = -3

-9/-3 = 3

Slope: 3

Answer:

Because angle 5 and angle 6 equal each other, it would mean that 4 and 7 equal each other. The sum of angles 4 and 5 is 180 because they are on the same line, intersected by another line. This means that they are supplementary angles. Since angles 5 and 6 equal each other, the other part of the the supplementary angle on both sides must equal each other. For example, if angles 5 and 6 equaled 60 degrees, the counterparts on the supplementary angle on both sides would have to be 120 to get to final sum of 180. This shows how angle 4 and 7 have to equal each other if 5 and 6 also equal other. Hope this helped! If its still confusing leave a comment and ill explain it in a different way. Good luck!

Answer:

The value of x is 4 and the value of y is 9

Step-by-step explanation:

In the attached pictures we can see that two lines are intersecting with each other and four angles are form. The angles opposite to each other are also called vertical angles.

The opposite pairs of angles are:

(10x-4)° and 6(x+2)°

(18y-18)° and 16y°

When two lines intersect each other, the vertical angles formed are congruent(Can also be called equal in measurement)

So,

[tex]10x-4=6(x+2)\\10x-4 = 6x+12[/tex]

Subtracting 6x from both sides

[tex]10x-4-6x = 6x+12-6x\\4x-4 = 12[/tex]

Adding 4 on both sides

[tex]4x-4+4 = 12+4\\4x = 16[/tex]

Dividing both sides by 4

[tex]\frac{4x}{4} = \frac{16}{4}\\x = 4[/tex]

AND

[tex]18y-18=16y[/tex]

Adding 18 on both sides

[tex]18y-18+18 = 16y+18\\18y = 16y+18[/tex]

Subtracting 16y from both sides

[tex]18y-16y = 16y+18-16y\\2y = 18[/tex]

Dividing both sides by 2

[tex]\frac{2y}{2} = \frac{18}{2}\\y = 9[/tex]

Hence,

The value of x is 4 and the value of y is 9
