Answer:
B. 336 cm^3
Step-by-step explanation:
Set up a proportion: 135/x=240/y
135/189=240/y
135y=189(240)
135y=45360
y=336
Therefore, B. 336 cm^3
I hope this helped and have a good rest of your day!
Answer:
sq. units.
Step-by-step explanation:
The given function is
We need to find the area between x-axis and the given function from x=2 to x=5.
Left Riemann sum formula of area:
For given question,
Now,
Therefore, the required area is sq. units.
5(x + 1)....distribute the 5 thru the parenthesis...that means multiply the 5 by everything in the parenthesis.
5(x + 1) = 5 * x + 5 * 1 = 5x + 5
Answer:
= 3 3/5 yards
Step-by-step explanation:
If 1 piece = 3/5 yard
What about 6 pieces = ?
= (6 x 3/5) ÷ 1
= 18/5 ÷ 1
= 18/5
= 3 3/5 yards
If the amount of money you invested in the first fund is x and the second fund y, then 9% (or 0.09 by moving the decimal 2 spots)*x+0.03*y=1047 since the first fund paid 9% and the second 3%. In addition, for this year, we get
0.1*x+0.01*y=811.
We also have 0.09*x+0.03*y=1047, so we can multiply the top equation by -3 and add it to the second to get -0.21x=-1386. Dividing both sides by -0.21, we get x=6600. In addition, since 0.1*x+0.01*y=811, we can plug 6600 in for x to get 660+0.01*y=811 and by subtracting 660 from both sides we get 0.01*y=151. Multiplying both sides by 100 (since 0.01*100=1), we get y=15100
