Answer:
13
Step-by-step explanation:
You have to construct an equation to solve this. The equation has all the weights of the packages plus x over eight. Set this equal to 12.
You set up the equation like this because you are essentially calculating an average backwards. Usually, you know all the numbers, and you have to find the average. In this case you know the average but not all the numbers.
You add up all the numbers like you would normally do when finding an average. Instead of dividing the sum of the weights by 8, multiply it by 12 to solve for x.
The weight of the 8th package is 13.
Answer:
Step-by-step explanation:
Are you in Calculus? These are calculus concepts!
To calculate the rate of change here you must specify an interval, e. g., "what is the rate of change on the interval (0, 3)?"
If you know calculus: The 'rate of change' on the interval (a, b) is
f(b) - f(a)
r. of c. = --------------------
b - a
Have you used this formula before?
Because of the 'x^2' term this is NOT a linear function.
If you want more explanation, provide an interval on which you want the average rate of change and ask specific questions of your own.
1. 5 faces
2. 4 triangles
3. 6(4)1/2=12 in
4. 36in squared=91.44cm squared
5. 12(4)=48 in squared=121.92 cm sqaured
6. 82 in squared=208.28 cm squared
Answer:
21
Step-by-step explanation:
To solve this question, follow the steps below.
Step 01: Find the LCM of 5 and 6 (denomitators).
5, 6 | 2
5, 3 | 3
5, 1 | 5
1, 1
The LCM is 2*3*5 = 30
Step 02: Rewrite the fractions using 30 as the denominator.
To do it, divide 30 by the original denominator and multiply the result by the numerator.
Step 03: Solve the expression.
First, since the fractions have the same denominator, you can write them using only one denominator:
Now, remove the parentheses by solving the multiplications.
