Answer:
Step-by-step explanation:
how many coins: d + q = 200
value of the money .10d + .25q = 44
(ten cents for each dime and 25 cents for each quarter)
Now to solve by elimination:
1)multiply the first row by -10 so that the dimes will cancel out.
-.10d + -.10 q = 20 (don't do anything to second row)
.10d + .25q = 44
2) now add those up.
the dimes cancel out.
.15 q = 64
that does not divide evenly so there is something wrong with this problem.
So the way you would find it is a ratio.
1.
2. =(6)(17)/(2.5)
3. =102/2.5
4. =40.8
So the building would be 40.8 feet tall.
Answer:
X is 12 Y is 124
Step-by-step explanation:
left and right side have equal degrees of 56
so x would be 12 because you would multiply 4×12
since in total it will be 360 degrees
you add 56 and 56 together to get 112
then just subtract 112 from 360 and you get 248 then divide 248 by 2 and you have your bottom and top value of 124
Answer:
Step-by-step explanation:
4
-x²+3 / x =
So, we need to think about this problem as either what we have to multiply x by to get the equation, and do long division
= 4x³- x + 
Answer:
The generator will run for 6 hours.
Step-by-step explanation:
First, find the volume of the gas tank that is on the generator. I am told that the gas tank is a rectangular prism that has the dimensions of 20 cm, 15 cm, and 10cm.
Area of any prism = height * width * length
Area of prism = 20 cm * 15 cm * 10 cm = 3,000 cm cubed
I am told the important info that <u>1,000 cm cubed = 1 liter </u>
Therefore, 3,000 cm cubed = 3 liters
I am also told that the generator will run for 2 hours on 1 liter of gas
Lets make a ratio table:
Hours the generator will run for : liters of gas
2 : 1
6 : 3
the generator will run for 6 hours.
