Answer:
29
Step-by-step explanation:
6 or 7 inches
29 can't be
30 can be 6*5
31 (1*7)+(4*6)
32 can be (2*7)+(6*3)
:)
have a nice day
and u survived ::)))
Answer:
29 inches
Step-by-step explanation:
For the following I just used trial and error and experimented with the possibilities:
29 inches - This is the only one that does not work.
30 inches - We can use 5 of the 6 inch trains, so this is possible.
31 inches - We can use 4 of the 6 inch trains and 1 of the 7 inch trains, so this is possible.
32 inches - We can use 3 of the 6 inch trains and 2 of the 7 inch trains, so this is possible.
33 inches - We can use 2 of the 6 inch trains and 3 of the 7 inch trains, so this is possible.

Point Q is plotted on the coordinate grid. Point P is at (20, −30). Point R is vertically above point Q. It is at the same distance from point Q as point P is from point Q. Which of these shows the coordinates of point R and its distance from point Q?
"On a coordinate grid from negative 50 to positive 50 in increments of 10, Point Q is plotted at the ordered pair negative 40, negative 30."/>
On a coordinate grid from negative 50 to positive 50 in increments of 10, Point Q is plotted at the ordered pair negative 40, negative 30.

Deanna borrowed $650 at 8% 0 simple interest. How much - 52 interest did she pay for 1 year?
Answer:
i = ($650)(0.08)(1) = $52
Step-by-step explanation:
The formula for simple interest is i = prt. Here p = $650, r = 0.08 and t = 1 (year). Then the simple interest Deanna paid for this one year loan was
i = ($650)(0.08)(1) = $52
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%

Answer for Question 4: 25
Step-by-step explanation:
1: [tex](4 + 3)^2[/tex] = [tex]7^2[/tex] = 49 (12 ÷ 4) = 3
3 + 49 = 52
2: [tex](12 * 9- 7^2) + 9[/tex] = 12 * 9 = 108 - 49 = 59 + 9 = 68
3: 28 ÷ 7 = 4 + [tex]6^2[/tex] = 40
4: [tex](2 * 7 + 4^2) - 5[/tex] = 2 * 7 = 14 + 16 = 30 - 5 = 25

A jar is filled with quarters and nickels in the ratio 1 2/5 to 2 1/3. If there are 24 quarters in the jar, what is the ratio in dollar value of quarters to that of the nickels???
Answer:
3 : 1
Step-by-step explanation:
The ratio of coins is ...
1 2/5 : 2 1/3 = 7/5 : 7/3 = 3 : 5
The quarters have 5 times the dollar value of nickels, so the ratio of dollar values is ...
5(3) : 5 = 3 : 1
The quarters have 3 times the dollar value of the nickels.
__
Additional comment
The number of nickels is 5/3 times the number of quarters, so is 5/3(24) = 40.
The dollar value of the quarters is 24($0.25) = $6.
The dollar value of the nickels is 40($0.05) = $2.
As above, the ratio of dollar values is 6:2 = 3 : 1.
__
There are a few different ways to compute the ratio of fractions. The one we used here may be a little unusual. All are equivalent.

The Mongolian Giant Sunflower produces seeds that are over 1 inch long, grow up to 18 feet tall, and flowers that are 1 ½ feet wide. Each flower head produces 1,000 seeds. You decide to harvest the seeds at the end of the season so that you can sell them the following spring. If you save 8 flowers for harvesting, how many seeds is that? Write your answer in scientific notation.
Answer:
8*10^3
Step-by-step explanation:
The Mongolian Giant Sunflower produces seeds that are over 1 inch long, grow up to 18 feet tall, and flowers that are 1 ½ feet wide. - All of this information is useless, all the question is asking is how many seeds do 8 flowers produce.
Each flower head produces 1,000 seeds. If you save 8 flowers for harvesting, how many seeds is that? - 1000*8 = 8000. 8000 is scientific notation is 8*10^3, as 10^3=1000, and 1000*8=8000 seeds.

Answer:
24x - 16
Step-by-step explanation
What we're doing here is factorisation
To factorise a number, you need to multiply the number outside of the bracket (in this case -4) by both of the inside numbers (-6x and 4).
First,
-4 x -6x
-4 x -6x = 24 , The x also needs to be kept- coming from the -6x, so the answer would be 24x.
You may think that because there are minuses involved, the answer would be -24x but you need to remember the rule that 2 negatives make a positive!
Next,
Multipying the outside number by the second inside again:
-4 x 4 = -16
Alongside the rule that two negatives make a postive, another rule is that one negative and one positive always result in a negative.
Finally,
Connect both of these answers
24x - 16 is the answer!
(The minus/negative symbol in the final answer is because the second multipication turned out negative, if the second number was positive, the answer would be 24x + 16.)

Simplify:
-30x^9/10x^17
Answer:
-3/x^8
Step-by-step explanation:
First, we simplify -30/10 which will be -3.
Next, we simplify x^9/x^17 which will be x^-8, since when dividing exponents, you subtract them. Sorry if this sounds confusing, but if this helps you better understand it, then here you go: I mean that y^n/y^z = y^(n-z).
x^-8 = 1/(x^8), and to find our answer, we multiply this by -3 to get an answer of:
-3/x^8
