Two cars are traveling down the highway at the same speed. If the first car increases its speed by 10 kilometers per hour, and the second car decreases its speed by 10 kilometers per hour, then the first car will travel the same distance in two hours that the second car travels in three hours. What is the original speed of the cars?
Answer:
50mph
Step-by-step explanation:
Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.
A = 50+10
b = 50-10
A = 60
B = 40
A2 = 120
B3 = 120
120 = 120
Answer
50 mph
Step-by-step explanation:
3(s-10)=2(s+10)
3s-30=2s+20
s=50

A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, can the company build 10 child bikes and 12 adult bikes in a week (1 point) No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100 Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100
Answer:
A
Step-by-step explanation:
4c + 6a < = 120 ...4(20) + 6(6) = 116 <== correct
4c + 4a < = 100....4(20) + 4(6) = 104 <== incorrect
what is 1+1-1
its a test and its impossible to solve

What is m% of n?? Helpp please
Answer:
m% of n is mn/100.
Step-by-step explanation:
Begin with a concrete example: What is 5% of n?
To answer this, rewrite 5% as 0.05 and multiply n by this 0.05.
Now revert to m% of n: Divide m% by 100% and multiply n by this m/100.
m% of n is mn/100.

Each cube in this solid figure is a unit cube.
What is the volume of this solid figure?
Enter your answer in the box.
Answer:
18 units cubed. (18units³) also, replace 'units' with whatever units you were given (cm, inches, etc.)
Step-by-step explanation:
(the answer below is assuming each cube has a length of one unit. If they have a different length, then multiply the final answer by the length squared) (answer x length x length)
answer: there are six rows of cubes with 3 cubes in each row each. Each cube is 1x1, so 6 x 3 x 1 x 1 = 18. (with units): 18units³
also, replace 'units' with whatever units you were given (cm, inches, etc.)
bobby has two poatatos he wants more so he pick 100 mor he sharees them amongst three friends EQUALY how many poatatos does each friend get?
Answer:
34
Step-by-step explanation:
If bobby already has 2 potatoes and picks 100 more, then he already has 102 potatoes. Now all you have to do is divide 102 by 3, which would be 34. If bobby is included with the friends, then all four of them would get 25.5 potatoes.
Answer: The answer is each friend gets 34 potatos
Step-by-step explanation: Each friend get 34 potatos because he first had 2 and then he picks 100 more so now he has 102. All you have to do know is divide 102 by 3 and you will get 34.
Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a radius of 13 feet and a height of 14 feet. Container B has a radius of 10 feet and a height of 18 feet. Container A is full of water and the water is pumped into Container B until Conainter B is completely full.
After the pumping is complete, what is the volume of water remaining in Container A, to the nearest tenth of a cubic foot?
Answer:
The percentage ≅ 48.4%
Step-by-step explanation:
The volume of water left in container A = 2197π - 1134π = 1063π feet³
* To find the percentage of the water that is full after pumping
is complete, divide the volume of water left in container A
by the original volume of the container multiplied by 100
∴ The percentage = (1063π/2197π) × 100 = 48.3841 ≅ 48.4%

A restaurant sells burritos for $8.00 each. The cost of the meat is $1.50 and the cost of the other ingredients is $1.00 for each burrito. Money made from selling burritos is positive. The cost of making burritos is negative. Profit is the money left after paying the costs.
How much profit would the restaurant make by selling 100 burritos?
What is the cost of making one burrito? (Remember that costs are negative.) Explain how you found your answer.
Write your answer in the space below.
Answer:
Profit for 100 burritos: $550
Cost to make one burrito: $2.50
Step-by-step explanation:
If a restaurant sells burritos for $8, that's a positive 8 dollars they earned. Then, we need to find what the cost was to make the burrito. If the meat is 1.50 and the cost for all the other ingredients is 1 dollar, then they lose 2.50 for every 8 dollars they make (for each burrito). So, to find the profit in one burrito, we would add -2.5+8, giving us an answer of 5.5. So, they earn 5 dollars and 50 cents each burrito and lose $2.50.
Now, we need to find the profit of 100 burritos
If one burrito is $5.50 in profit, then we take that amount and multiply it by 100. This is to make the illitsratution of selling 100 burritos. So, 5.50*100 would be 550! They would make $550 for 100 burritos, and lose 250 dollars on all of the burrito ingredients.

Which point is a reflection of (1.5, -4.5) across the x-axis and the y-axis?
A.
point I
B.
point J
C.
point K
D.
point L
E.
point M
Answer:
(1.5, 4.5 ) and (- 1.5, - 4.5 )
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ) , then
(1.5, - 4.5 ) → (1.5, 4.5 )
Under a reflection in the y- axis
a point (x, y ) → (- x, y ) , then
(1.5, - 4.5 ) → (- 1.5, - 4.5 )
If x- axis then y- axis
(1.5, - 4.5 ) → (1.5, 4.5 ) → (- 1.5, 4.5 )

A cookie recipe calls for ¾ cup of sugar. You have the
following measuring cups: 1 cup, ½ cup, ⅓ cup, ¼ cup, ⅛ cup, and a tablespoon (which is 1/16 cup).
Suppose your ¼ cup is missing. How would you measure ¾ cups of sugar using at least two of the other measuring cups? Show your work.
Answer:
1/2 cup and 2 1/8 of a cup
Step-by-step explanation:
1/8 +1/8=1/4
1/2 is equaled to 2/4
so 2/4+1/4=3/4
Help please....If you can, draw on the attachments.
Answer:
Problem 3: Just 33 draw 4 boxes of 11 and one with 11
Problem 4: 30
Problem 5: Naomi
Step-by-step explanation:
For problem three since you are multiplying the same equation by 4 its basically (2+9)+3(2+9) so you can just cancel out the 2+9 from both and you are left with 3(2+9) which is just 33
For problem 4 100-(12x4)=52 and 10+(3x4) = 22 and when you subtract the two (52-22) you get 30
For problem 5 you get 18 with your equation and so since Carlos' equation gets 9 and Miranda gets 24 and Will gets 35 the only one left is Naomi which also gets 18 just like you.

Answer:
See below:
Step-by-step explanation:
Hi!
It seems like you have two answers in the boxes already, but it is not correct.
Firstly, you cannot tell mean from a box plot. The first box should be moved to the last category.
Your second boxes seems to be correct though.
As far as the remaining boxes, I can help with those too!
Median: The median is identifiable in a box plot, as the line in the boxes themselves are the medians. The medians do line up, therefore they belong in category 1.
Minimum: This is the value that is the least. We can tell this from a box plot, by looking at the most left line, or the "whiskers", as some teachers call them. For our box plots, the minimum is 4. They line up exactly. Therefore, this box should go in the first category.
IQR: The IQR "measures the spread of the middle half of your data". In these box plots, the IQR is different. Therefore, it belongs in the second category.
Mode: This is the value that appears most often in a set of data values. You cannot tell this from a box plot. Therefore, it belongs in the last category.
I hope I could help!
