Let come up with a value to represent 7th graders and 6th graders.
7th=x
6th=y
Y= 0.25x
X+y=135
Plug in 0.25x for Y
X+0.25x=135
X=108 7th graders
Y=27 6th graders
Let's make an equation to show how to get how many people were in 105,000.
But, with a decrease, you have to decrease it from 100.
100-12.5
87.5
So it will be 87.5 of what it was previously. Now let's get to the equation.
.875x=105,000
Let's divide each side.
105,000÷.875
120,000
Let's check if this was a 12.5% decrease.
120,000×0.125
15,000
120,000-15,000
105,000
So the population of 2010 was 120,000 people.
You need to pay $40 to make your balance 0 and then another $40 to make it $40.
In all you will have to pay $80
Answer:
380.16
Step-by-step explanation:
To find the capacity of a tank: multiply the length by the width to get the area. Then multiply the area by height to get volume. Finally, multiply the volume by 7.48 gallons per cubic foot to get capacity.
The result of the product with
, we can see that Han neglected the zero taking<u> 50 the same as 5</u> which is wrong
Given the polynomial functions
r(x) = ![10x^4](https://tex.z-dn.net/?f=10x%5E4)
t(x) = ![5x^3](https://tex.z-dn.net/?f=5x%5E3)
Taking the product of both functions:
P(x) = r(x) * t(x)
P(x)= ![10x^4\times 5x^3](https://tex.z-dn.net/?f=10x%5E4%5Ctimes%205x%5E3)
P(x) = ![(10\times 5) \times(x^4\times x^3) = 50x^7](https://tex.z-dn.net/?f=%2810%5Ctimes%205%29%20%5Ctimes%28x%5E4%5Ctimes%20x%5E3%29%20%3D%2050x%5E7)
Comparing the result of the product with
, we can see that Han neglected the zero taking<u> 50 the same as 5</u> which is wrong.
