Answer:

RP = 8

Step-by-step explanation:

RQ + QP = RP (segment addition theorem)

(x + 1) + 7 = 2x + 8 (substitution)

Add like terms

x + 8 = 2x + 8

8 - 8 = 2x - x

0 = x

x = 0

✔️RP = (x + 1) + 7

Plug in the value of x

RP = (0 + 1) + 7

RP = 1 + 7

RP = 8

Answer:

$4.875 Rounded to nearest cent:$4.88

Step-by-step explanation:

50%=0.50

3.25*0.50=1.625

$3.25+$1.625=$4.875

The rule is five or more add one more. So add one to the 7 making it 8. Make sure to take out the five. And you get $4.88

Answer:

$6.50

Step-by-step explanation:

(I submitted and it was right)

3.25 = 50%

3.25 + 3.25 = 6.50

6.50 = 100%

4. A​ post-lunch nap decreases the amount of time it takes males to sprint 20 meters.

Step-by-step explanation:

This question wants us to state the claim and the hypothesis.

This researchers claim can be found in the first sentence of this question.

Claim: post lunch nap decreases the time it takes to run for 20 meters.

The correct answer option for the claim is the 4th answer option. And it means that sleeping after lunch reduces the time it takes males to run in a 20m race.

B. Hypothesis

H0: Ud <= 0

H1: Ud > 0

d = is the race time without a nap - race time with a nap

Answer:

Dylan delivered 140 parcels on Wednesday.

Step-by-step explanation:

On Wednesday:

On Wednesday, he delivered x parcels.

Thursday:

10% more than Wednesday, so 100 + 10 = 110% of x = 1.1x

Friday:

50% pless than on Thursday, so 100 - 50 = 50% of 1.1x = 0.5*1.1*x.

THis is equals to 77. So

[tex]0.5*1.1x = 77[/tex]

[tex]x = \frac{77}{0.5*1.1}[/tex]

[tex]x = 140[/tex]

Dylan delivered 140 parcels on Wednesday.

Answer:

17/15 _53/6

Step-by-step explanation:

The other is problem 1 and the other is problem 2

PROBLEM #1:

As the problem is, we are adding a negative. I can change this to be a subtraction problem. It looks like this: [tex]2\frac{1}{3} - 1\frac{1}{5}[/tex].

To be able to add or subtract fractions/mixed numbers, we have to first get common denominators. A common denominator is a shared multiple between two numbers. So, we need to find the smallest number that both 3 and 5 (the denominators of each fraction) can do into evenly. In this case, that number is 15! To transform the fractions to have common denominators, we will multiply 1/3 by 5/5 and 1/5 by 3/3 (multiply the top and bottom by 5 or 3 so that the denominator is 15). Here is our new problem: [tex]2\frac{5}{15} - 1\frac{3}{15}[/tex].

All that's left to do now is subtract! Since our first fraction is larger (this is important!) we don't need to do any borrowing. So, we'll subtract 2 - 1 = 1, and 5/15 - 3/15 = 2/15. Therefore, if we put those pieces back together, we get 1 2/15 ([tex]1\frac{2}{15}[/tex]).

PROBLEM #2:

For this problem, we have two negative mixed numbers. In this case, we will simply be adding the negative numbers because both are negative. For example, -2 + -4 = -6. Here is the rewritten problem: [tex]-3\frac{1}{2} + -5\frac{1}{3}[/tex].

Our first step is to get common denominators. In this case, that common denominator will be 6: [tex]-3\frac{3}{6} + -5\frac{2}{6}[/tex].

Now, we have to add! -3 + -5 = -8, -3/6 + -2/6 = -5/6. Once we've added the parts, we can put them back together to form the answer: -8 5/6 ([tex]-8\frac{5}{6}[/tex]).

Hope this helps!! :)

Answer:

f(x) > h(x) > g(x)

Step-by-step explanation:

For the average rate of change of a function between x = a and x = b,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

From the table given,

Average rate of change of function 'f' between x = 1 and x = 3,

Average rate of change = [tex]\frac{f(3)-f(1)}{3-1}[/tex]

                                        = [tex]\frac{15-7}{3-1}[/tex]

                                        = 4

For the function 'g',

g(x) = 2x² - 18x

Average rate of change = [tex]\frac{g(3)-g(1)}{3-1}[/tex]

g(3) = 2(3)²- 18(3)

      = 18 - 54

      = -36

g(1) = 2(1)² - 18(1)

      = 2 - 18

      = -16

Therefore average rate of change = [tex]\frac{-36+16}{3-1}[/tex]

                                                         = -10

From the graph attached,

Average rate of change of the graph between x = 1 and x = 3,

Average rate of change = [tex]\frac{h(3)-h(1)}{3-1}[/tex]

h(3) = 7.5 [Although the graph is not clear]

h(1) = 2

Average rate of change = [tex]\frac{7.5-2}{3-1}[/tex]

                                        = 2.75

Therefore, order of rate of change (from greatest to the least) for the given functions will be,

f(x) > h(x) > g(x)

Answer:

the slope is -2x

Step-by-step explanation:

Its negative because the line is going towards the negatives, and 2 because the slope is rise over run. the line is going up 2 and over 1, which means 2/1, which simplifies to 2

Answer:

-2x -2

Step-by-step explanation:

The slope is negative because it is going down instead of up

y intercept is -2

Use rise over run

Rise is y x is run select 2 points and check rise/run

Slope= - x -(y)

55 sold for $35

Step-by-step explanation:

20x+35y=2605

y=(98-x)

20x+35(89-x)=2605

Solve for x

20x+3115-35x=2605

20x-35x=2605-3115

Answer:

The y intercept of the inverse function of f(x) = 3/4 x + 12 is -16, option A is correct.

To find the y-intercept of  f⁻¹(x), we can start by finding the inverse function f⁻¹(x) first.

Let y = f(x) = 3/4 x + 12

To find f⁻¹(x), we can first swap x and y, and then solve for y:

x = 3/4 y + 12

x - 12 = 3/4 y

4/3 (x - 12) = y

Therefore, f⁻¹(x) = 4/3 (x - 12)

The y-intercept of f⁻¹(x) is the value of f⁻¹(x) when x = 0.

f⁻¹(0) = 4/3 (0 - 12)

= -16

Hence, the y intercept of the inverse function of f(x) = 3/4 x + 12 is -16, option A is correct.

Answer:

Area of the top = 24 square inch

Step-by-step explanation:

Volume of the given prism = Area of the base or top of the prism × Height of the prism

By substituting the values in the formula,

Area of the top = [tex]\frac{312}{13}[/tex]

Area of the top = 24 square inch
