Answer:
77.75%
Step-by-step explanation:
We just have to find the sums of the product of Joey's averages and their contribution to the total grade.
Test: 0.45 * 0.8 = 0.36 = 36%
Quizzes: 0.3 * 0.85 = 0.255 = 25.5%
Homework: 0.25 * 0.65 = 0.1625 = 16.25%
Total: 36% + 25.5% + 16.25% = 77.75%
Answer: Option C. 8,064 pounds
Solution:
Unit weight: U=63 pounds/foot^3
Total Weight: W=?
W=U*V
Volume: V
Length: l=8 feet
Width: w=4 feet
Height: h=4 feet
V=l*w*h
Replacing the knwon values in the formula above:
V=(8 feet)*(4 feet)*(4 feet)
V=128 feet^3
Replacing in the formula of total Weight:
W=U*V
W=(63 pounds/foot^3)*(128 feet^3)
W=8,064 pounds
Answer:
-3
Step-by-step explanation:
Slope is rise divided by run. Y2-Y1 Divided by X2-X1
You get 6 divided by -2
-3
Answer:
1 represents the number of years passed.
step -by-step explanation:
The amount of a radioactive isotope decays in half every year. The amount of the isotope can be modeled by f(x) = 346 (1/2)x and f(1) = 173
Here 1 represents the number of years that passed.
So 1 represents the number of years.
