Answer:
$1100 at 9%$1300 at 12%Step-by-step explanation:
The amount of interest earned in one year is the product of the interest rate and the amount invested at that rate. The total interest earned is the sum of the amounts of interest earned on each investment.
Let x represent the lower interest rate. Then the higher rate is x+0.03 and the total interest earned is ...
1100x +1300(x+0.03) = 255
2400x +39 = 255 . . . simplify
2400x = 216 . . . . . . subtract 39
x = 216/2400 = 0.09 = 9% . . . . divide by the coefficient of x
Rosa invested $1100 at 9%, and $1300 at 12%.
I typically give 12% of money I receive to my church. My uncle died recently and left me some money. I donated $408 to my church in his memory. How much did he leave to me in his will?
your uncle left you with "x" total, which is the 100%, now, we also know that 408 is 12% of that, so
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 408& 12 \end{array} \implies \cfrac{x}{408}=\cfrac{100}{12}\implies \cfrac{x}{408}=\cfrac{25}{3} \\\\\\ 3x=10200\implies x=\cfrac{10200}{3}\implies x=3400[/tex]
what is is the volume of a box with 3 inches long 1 inch wide and 5/3 inch tall
Answer:

Evaluate the double integral int int y^3 dA where D is the triangular region with vertices (0,1), (7,0) and (1,1).
Answer:
1/5
Step-by-step explanation:
Refer to the image for the region. I've chosen to "scan" the region horizontally for convenience sake, so x varies for values between the green and the red line, and y varies from 0 to 1.
The two lines have equations [tex]x=7-6y[/tex] (red line) and [tex]x=7-7y[/tex] (green line). Since we're integrating first with respect to x, it's easier to write the equation like that and not as [tex]y=mx+q[/tex] since they will become our new limits of integration
Our double integral will become
[tex]\int \limits_0^1 \ \ \int \limits_{7-7y}^{7-6y}y^3dxdy = \int \limits_0^1 y^3x|\limits_{7-7y}^{7-6y} dy =\\\int \limits_0^1 y^3[(7-6y)-(7-7y)]dy = \int \limits_0^1y^3(y)dy =\\\int \limits_0^1 y^4dy =\frac15y^5|\limits_0^1=\frac15[/tex]

find the area bounded by the Curves y=4-x² and y
The area bounded by the Curves y=4-x² and y = 2x + 1 is 10 1/3 units.
What is area?Area is the amount of space occupied by a two dimensional shape or object.
y = 4 - x² and y = 2x + 1
4 - x² = 2x + 1
x² + 2x - 3 = 0
(x + 3)(x - 1) = 0
x = -3; or x = 1
The area (A) is given by:
[tex]A=\int\limits^1_{-3} {x^2+2x-3} \, dx \\\\A=10\frac{1}{3}[/tex]

Step-by-step explanation:
Water is pumped from a tank at constant rate, and no more water enters the tank. If the tank contains 22,917 L at 2:45 PM and 8,077 L at 5:25 PM the same day, how much water will the tank contain at 6:10 PM that day?
The amount of water that the tank will contain at 6:10 PM that day is 4174 L.
What is a Conversion Rate?
The conversion rate of a physical quantity is the method by which a unit of measurement is changed from one process to another by following a standard conversion rate and dimensional analysis.
From the information given:
The difference in the time from 5:25 PM to 2:45 PM is 2 hours:40 minutesIf we convert 2 hours:40 mins to minutes, we have = 160 minutesThe difference in the water in the tank within these two periods is:
= 22917 L - 8077 L
= 14840 L
In one minute, the amount of Liter is:
= 14840/160
= 92.75 Liter/minute
Similarly, between 6:10 pm and 5:25 pm, there are 45 minutes difference.
Therefore, the amount of water that the tank will contain at 6:10 PM that
day is;
= 45 minutes × 92.75 Liter/minute
= 4174 Liters

The dotted lines show how piano wire
is used to slice this cube. What will be
the shape of the cross section?
Answer:
C. rectangle (not a square)
Step-by-step explanation:
So image that the wire just sliced that piece of the cube right off:
It would give you a triangular prism,
HOWEVER, this is asking for the cross section:
The part of this triangular prism that was actually connected to the cube
and in this case, it would show that the bottom of the cut off part is rectangle.
You can also think of this as: What shape would be left over on the cube?
Cutting this piece off would give you a shape left over that is a rectangle.

Answer:
5 payments
Step-by-step explanation:
First we add up the prices for the lunches and the movies :)
3 x 5 = 15
15 + 9.5 = 24.5
Second we subtract the 24.5 from the 35 :)
35 - 24.50 = 10.5
Now we divide the price of the cd player by the 10.50 to get the total number of payments :)
50/10.5 = 5
Finally to check it one more time, we multiply the 10.5 by 5 and if it equals 50 or over, it is correct!! :D
10.5 x 5 = 52.5!!!
You did it!
Your correct answer is 5 payments!!
