Answer:
The total interest earned at the end of the year was $ 820, and the interest generated by the total deposited was 10.25%.
Step-by-step explanation:
Given that last year, Manuel deposited $ 7000 into an account that paid 11% interest per year and $ 1000 into an account that paid 5% interest per year, and no withdrawals were made from the accounts, to determine what was the total interest earned at the end of year and what was the percent interest for the total deposited, the following calculations must be performed:
7000 x 0.11 + 1000 x 0.05 = X
770 + 50 = X
820 = X
8000 = 100
820 = X
820 x 100/8000 = X
82,000 / 8,000 = X
10.25 = X
Therefore, the total interest earned at the end of the year was $ 820, and the interest generated by the total deposited was 10.25%.
Answer:
(x, y) → (-x, -y)
Q"(4, 1) → Q'(-4, -1)
R"(6, -5) → R'(-6, 5)
S"(3, -4) → S'(-3, 4)
T"(1, -1) → T'(-1, 1)

this might be right, sorry if im wrong
Answer:
10.50 is the interest
Step-by-step explanation:
B = p(1 + r)^t
P = 50
r = .10
t = 2
B = 50(1 + .1)^2
= 50(1.1)^2
= 50(1.21)
= 60.5
But we want to know the interest and this is the balance
60.5- 50 = 10.5
Answer:
Step-by-step explanation:
This looked very difficult UNTIL I looked at the pyramid as ONE HALF of a larger pyramid! Image a mirror image of the pyramid creating a pyramid that is 12 cm of the front and back side and 6 cm on the left and right edge.
IT IS NO LONGER A SQUARE PYAMID so you need the volume for a rectanglar pyramid
The volume of a square pyramide is .....
V = side² × (height / 3)
The volume of a rectangular pyramide is .....
V = base area × (height / 3)
= length × width × (height / 3)
= 12 × 6 × 10 / 3 cm³ BUT REMEMBER we want only HALF of the
= [12 × 3 × 10] divide by 2 cm³ Rectangular pyamid
Volume of the image shown in the diagram is ....
= 360 / 2 cm³
= 180 cm³ <----------------- Final Answer
<u>Answer:</u>
The temperature change per hour was -3 degrees per hour.
<u>Step-by-step explanation:</u>
We know that the temperature fell from 
degrees to 
degrees in a time period of 
hours.
So to find the rate of change of the temperature, we will divide the change in temperature by the number of hours.
For that, we will change the mixed number into improper fractions and then solve:
Temperature change per hour = 
Therefore, the temperature change per hour was -3 degrees per hour.
