Grace was given the description “three less than the quotient of a number squared and nine, increased by eight” and was asked to evaluate it when n = 6. Her work is shown below.
In which step did she make an error?
step 1
step 2
step 4
step 5
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...
Dustin is riding his bike from Logan, Utah to Jackson Hole, Wyoming in a bike race. He must ride at least 200
miles before he will complete the course. He has already biked 56 3/4
miles.
If he can bike roughly 18 5/8
mph, how many more hours will it take him to finish biking at least 200
miles? Round your answer to the nearest whole number of hours.
Enter your answer as a whole number, like this: 42
Answer:
0
Step-by-step explanation:
If he has already biked 5634 miles, he’s past 200 miles.

Step-by-step explanation:
Supplementary angles add up to 180 degrees. When the angles are placed next to each other, they should add up to 180. Let's try it... 130+50 = 180. Therefore, these angles are supplementary.
Also, for extra help, 180-degree angles make a straight line, like this one. When you get stuck, you can always refer to websites such as Khan Academy for practice and explanations. (https://www.khanacademy.org)

What is the Mean of this data set {2,5,5,6,8,8,9,11}
NO LINKS
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!

Please help! Thank you!!
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.....

John had a total of $150. He purchased a DVD box set which costs $50 as well as a single DVD. He is left with $75. Which equation could be used to find the cost p of the DVD?
150 − 50 + 75 = p
150 + 50 + p = 75
50 + p + 75 = 150
150 + 50 + 75 = p
--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.

Please help I need help with #17, 19, and 21
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:
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:
528 dollars
Step-by-step explanation:
The starting price is $600. And it goes down by 20% then comes back up 10% so steps are:
First we got 20% off so I did 100 - 20 and got 80%
1: 80% * 600 = 80/100 * 600 = 480
Then we get an increase of 10% so I multiplied 110% with 480 which was our new price
2. 110/100 * 480 = 11 * 48(simplifying)
= 528
please help, i need help with thee two problems and i swear if you are one of those people that just put links as scams, pls dont:D

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

#1. What is the value of the lower quartile (Q1)?
#2. What is the IQR (inter-quartile range)?
#3. What is the range?
#4. What is the median?
#5. What is the value of the upper quartile (Q3)?
#6. Which of the four quartiles has the smallest range?
A. 1st quartile
B. 2nd quartile
C. 3rd quartile
D. 4th quartile
#7. What is the maximum value shown in the box-and-whisker-plot?
--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 :>
Please answer. Thanks!
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:
Step-by-step explanation:
Check boxes 1 and 4 (these two are true!).
1. Quadrant I is the top right quadrant on the graph. All values for x and y are positive in quadrant 1. Quadrant III is the bottom left and both coordinates (x,y) would always be negative.
4. Multiplying a number by itself is the same as squaring that number or raising it to the power of 2. In all cases, squaring a number results in a positive value. Therefore, no matter if the coordinates are positive or negative, the new coordinates will both be positive after being multiplied by themselves. This will result in the new coordinates being in Quadrant I.
Find the volume of the prisms. Show work!
1. Answer = About 1451.42 m³
First, we need to find the volume of the cube:Formula: πr²hVolume = π * 3² * 50 = 1413.72 m³Second, we need to find the volume of the cone:Formula: (πr²h)/3Volume = π * 3² * 4 = 37.69 m³Third, we need to add these two volumes to find the total volume of the figure.1413.72 m³ + 37.69 m³ = 1451.42 m³.2. Answer = 960 m³
Formula: (1/2(b*l)) * 20First, we need to find the area of the base (1/2 * b* l).1/2 * 8 * 12 = 48.Second, we need to multiply the area of the base by the height to get the volume.B * h = 48 * 20 = 960 m³.
