<u>The difference between the estimated number an 1000 is:</u>
<u>The exact number:</u>
<u>The difference between the exact number and 1000 is:</u>
Independent variable: the variable that affects the dependent variable and creates a change
Dependent variable: depends on the independent variable
1. Independent variable: John’s age
Dependent variable: height
2. Independent: gallons of milk
Dependent: cups of milk
3. Independent: population
Dependent: number of representatives
4. Independent: Number of seats
Dependent: amount of tickets
5. Independent: time
Dependent: plane’s altitude
6. Independent: more music download
Dependent: more money spent
X=30
explanation:
if we are given that the volume is 27,000, we know that x^3 should equal 27,000
so take the cube root of 27,000 and that is 30
Answer:
B. 12.5%
Step-by-step explanation:
Add all the hours together to get 20. We make the assumption that 20 is 100% since it is our output value. We next represent the value we seek with x. From step 1, it follows that 100%=20. In the same vein, x%=2.5.This gives us a pair of simple equations:
100%=20(1)
x%=2.5(2)
By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left hand side) of both equations have the same unit (%); we have
=
Taking the inverse (or reciprocal) of both sides gives us this:

>> x=12.5\%
Therefore, 2.5 is 12.5% of 20.
Answer:
area of square=l²
25sq.cm²=l²
l=5sq.cm
area of trapezium =(1/2)(a+b)h
a=5,b=(12+5)=17,h=5
area of trapezium=(1/2)(22)(5)
area=55cm²
