Plz help marked BRAINLIEST

Answer:

11.6667 mi/h

Step-by-step explanation:

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

Answer:

Step-by-step explanation:

All the angles in a triangle have to add up to 180 degrees.

#17.)

45+50=95

180-95=85

x=85

#18.)

This one is a little different. The furthest two angles are complimentary which means that they add up to 180 degrees (a straight line.) Once you find the missing angle to that one, you can do the same thing as you did in #17.

180-118=62.

25+62=87

180-87=93

x=93

#21.)

For this one a slightly larger equation is needed. Since we don't have a definite number for the bottom left angle, we have to use x+2 as our number. We first have to find the bottom right angle though.

180-108=72

x+x+2+72=180

2x+74=180

2x=106

x=53

Answer

#17=85

#19=93

#21=53

Answer: 6.8

Step-by-step explanation:

Add all of them, and then divide them by 8

Answer:

The mean is 6.75

Step-by-step explanation:

There are 8 numbers in the set. Add them all, and then divide by 8.

2 + 5 + 5 + 6 + 8 + 8 + 9 + 11 / 8=54/8=6.75

So, the mean is 6.75!

Hope this answer helps!

Answer:

n=2

Step-by-step explanation:

Answer:

The answer is n=2.

Step-by-step explanation:

First, combine like terms, so the problem then looks like 3.6n-0.12=7.08.

Then, add 0.12 to both sides, which now looks like 3.6n=7.2.

Finally, divide both sides of the equation by 3.6, and the final answer is n=2.

2. Answer = 960 m³

--Answer--

50 + p + 75 = 150

--Explanation--

The total number of money he had originally is 150. If he is left with 75, that starts us with 150 = 75 ______.

He spend something that was 50 dollars, so add that to 75 which equals 125.

Subtract 125 from 150 and you get 25. 25 is the cost of the single DVD, so we'll make 25 "p."

The cost of the DVD box set, the single DVD, and how much he is left with equals how much money he had originally.

That would make it 50 + p + 75 = 150.

Answer:

3. y=3x-4

4. -1/2x+6

Step-by-step explanation:

Answer:

Step-by-step explanation:

1) x +22.5 = 49.25

Subtract 22.5 from both sides

x + 22.5 - 22.5 = 49.25 - 22.5

x = 26.75

Checking:  LHS = x + 22.5 = 26.75 + 22.5 = 49.25 = RHS

2) 37.2 = n - 12

Add 12 to both sides

37.2 + 12 = n - 12 + 12

49.2 = n

n = 49.2

3) 55t = 176

Divide both sides by 55

[tex]\frac{55t}{55}=\frac{176}{55}\\\\t = 3.2[/tex]

--Answer--

1. 4

2. 6

3. 14

4. 9

5. 10

6. A

7. 20

--Explanation--

1. The lower quartile is always the left side of the box.

2. The IQR is Quartile 1 minus Quartile 2, so you could subtract the number at the right of the box with the left.

3. The range is the highest number minus the lowest number. (The numbers that stretch out all the way til the lines stop)

4. The median is the line in the middle of the box.

5. The upper quartile is right of the box. (the vertical line)

6. The Lower Quartile Is Always Smaller Than The Upper Quartile.

7. The number all the way to the right of the number line.

Sorry if anything is incorrect, but I hope it helps :>

Answer:

91 scores

Step-by-step explanation:

Let x be the score meg get on fourth test,

Let the total sum of the scores in four test = 45 + 48 + 56 + x (91) = 149 + x

149 + x = 240

x = 91

So to put this in easier words, (45+48+56+91)/4=91

Hence, she should get 91 scores on the fourth test to get an average score of 60.

I hope this helps you, Enjoy!

Answer:

3

Step-by-step explanation:

ugh i hate those ppl with the links

anyways

1) 16t^2 = 144

4t = 12

t = 3

2) x^2 + 10x + 25 = 9

x^2 + 10x + 16 = 0

(x+8)(x+2) = 0

x = -8 or -2

Hope this helps :)

Answer:

ANSWER TO 1 is t = 3

ANSWER TO 2 is x = -2

Step-by-step explanation:

2) x^2 + 10x + 25 = 9

x^2 + 10x + 16 = 0

(x+8)(x+2) = 0

x=-2

1) 16t^2 = 144

4t = 12

t=3

Answer:

Graph D

Step-by-step explanation:

For graph A)

Equation would be: y = 2x + 1

For graph B)

Equation would be: y = 2x - 1

For graph C)

Equation would be: y = -2x - 1

For graph D)

Equation would be: y = -2x + 1

Hope this helps!

answer : D

steps :

graph the line using the slope and y-intercept, or two points.

slope: −2 (down 2, right 1)

y-intercept: (0,1) (where the line intercepts the y axis)

your points for your line:

[tex]\left[\begin{array}{ccc}x&y\\0&1\\1&-1\end{array}\right][/tex]

solution : the graph in answer D.

hope this helps !

Step-by-step explanation: So, she took 2 from each of the volunteers, and there were 5 volunteers in total. What I did, was I found out how many people were taken in total and given to the teachers, which was 10 (2*5), and then I added it to the total number of flyers still with the volunteers (40), which equals 50. Divide that by 5 (number of groups) and you get 10.

Answer:

[tex] \rm Numbers = 4 \ and \ -3.[/tex]

Step-by-step explanation:

Given :-

And we need to find out the numbers. So let us take ,

According to first condition :-

[tex]\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}[/tex]

Hence the numbers are 4 and -3

Step-by-step explanation:

[tex]integers \: = x \: and \: y \\ then \: x \times y = - 12 ....(1)\\ x + y = 1.....(2) \\ x = 1 - y.....(3) \\ put \: (3 )\: in \: (1) \\ then \: (1 - y) \times y = - 12 \\ y - {y}^{2} + 12 = 0 \\ {y}^{2} - y - 12 = 0 \\ factorise \\ {y}^{2} - 4y + 3y - 12 = 0 \\ y( y - 4) + 3(y - 4) \\ (y - 4)(y + 3) \\ y = 4 \: and \: - 3 \\ thank \: you[/tex]

Hello! I believe that I have the answer.

My answer: The total amount was $47.79.

8% of $37.50 is $3. $37.50 + $3 = $40.50.

18% of $40.50 is $7.29. $40.50 + $7.29 = $47.79.

I hope that helps! Please let me know if my answer is incorrect.

Answer:

115ft

Step-by-step explanation:

Think of it as two rectangles. One rectangle would be 10ft long and 13-5 or 8ft wide. The other rectangle would be 5ft long and 10-3 or 7 ft wide. Find the area of the two rectangles and add them. Rectangle 1= 10•8 or 80ft. Rectangle 2= 5•7 or 35ft. 80+35=115ft. Juan would need at least 115ft of rubber flooring.

Answer:

She didn't fudge it up, because I put it in a calculator and I got the same answer as in the image provided. Maybe there was a typo in the question or something...

The answer is 86

Following PEMDAS, which is:

parentheses

exponents

multiplication

division

addition

subtraction

I found that the answer was 86

Answer:

-10.

Step-by-step explanation:

Step 1: Explain/define

This problem contains more than one operation. This means we should solve this using a special acronym known as PEMDAS.

P (Parenthesis)

E (Exponents)

M/D (Multiplication/division, whichever comes first)

A/S (Addition/subtraction, whichever comes first)

This is the correct sequence of steps when solving expressions with multiple operations.

PEMDAS can be remembered using the mnemonic "Please Excuse My Dear Aunt Sally."

------------------------------------------------------------

Step 2: Solve.

REMEMBER PEMDAS!

Expression given: 4 × 3 + 2 × 9 - 40

There are no parentheses.

There are no exponents.

There is multiplication, but no division.

4 × 3 + 2 × 9 - 40

12 + 18 - 40

There is addition and subtraction. Remember to solve whichever comes first.

12 + 18 - 40

30 - 40

30 - 40 = -10.

I, therefore, believe the answer to 4 × 3 + 2 × 9 - 40 is -10.

Please let me know if you have any further questions.

Answer:

108

Step-by-step explanation:

So, to start, we can calculate the fuel used in March by using the following equation:

(40x240)/100

Which is 96. So the furnace burned 96 gallons of fuel in March and was left with 144 gallons. Now we need to find out how much of its remaining fuel it burned in April, so we use this:

(25x144)/100

Which is 36. So it burned another 36 gallons of fuel in April, leaving it with 108 gallons still in the tank.

Answer: i think is 108 i hope this help sorry.....
