Well see here that it practically gives us the answer. The submarine rises 4.3 meter each minute of the first 15 minutes. Multiplying these two given numbers you get 64.5 . Great we're halfway through. Now onto the second equation. 5.2 times 12 . easy right? The answer round to 62.4 . Now all that's left to do is add the two together. After the 27 minutes the submarine should be at an elevation of 126.9 feet. rounding to 127 if you teacher requires you to round the numbers.
Answer:
There are 1849 tiles on the whole wall.
Step-by-step explanation:
If there are 85 tiles along the two diagonals, we can use the following rule:
![\frac{85+1}{2}=43](https://tex.z-dn.net/?f=%5Cfrac%7B85%2B1%7D%7B2%7D%3D43)
So we have 43 tiles in the first diagonal and 85-43 = 42 in the second diagonal.
Now, as we have a square the side will have 43 tiles so the total area will be cover with:
![A=43*43=1849](https://tex.z-dn.net/?f=A%3D43%2A43%3D1849)
Therefore, there are 1849 tiles on the whole wall.
I hope it helps you!
Answer:
x = 3 or x = 2 or x = -1 or x = -5
Step-by-step explanation:
Solve for x:
((x - 3) (x - 2) (x + 1) (x + 5))/x = 0
Multiply both sides by x:
(x - 3) (x - 2) (x + 1) (x + 5) = 0
Split into four equations:
x - 3 = 0 or x - 2 = 0 or x + 1 = 0 or x + 5 = 0
Add 3 to both sides:
x = 3 or x - 2 = 0 or x + 1 = 0 or x + 5 = 0
Add 2 to both sides:
x = 3 or x = 2 or x + 1 = 0 or x + 5 = 0
Subtract 1 from both sides:
x = 3 or x = 2 or x = -1 or x + 5 = 0
Subtract 5 from both sides:
Answer: x = 3 or x = 2 or x = -1 or x = -5
Answer:
70 millimetres is 7e-5 liters

Mark me brainliest if I'm right :)
The sale price is $3. 17%, or .75*$12 is $9. $9 is the amount of money that you save on the DVDs. So, you would do $12-$9 which would equal $3. You would end up paying $3 for the DVD. In this problem, $12 represents the original price of the DVD and $9 is the amount of money you save on the DVD. $3 is the amount of money you spend on the DVD. $3 is also the sale price of the DVD. In any type of these problems you do %* original price. This will give you the amount of money you save. You subtract the amount of money you save from the original price, and you will get the sale price which is what you will be paying for whatever is being represented in the problem. Hope I helped! <span />
