Answer:
Elena invested $ 1,700 at 5%, $ 700 at 4%, and $ 600 at 3%.
Step-by-step explanation:
Given that Elena receives $ 131 per year in simple interest from three investments totaling $ 3000, and part is invested at 3%, part at 4% and part at 5%, and there is $ 1000 more invested at 5% than at 4%, to find the amount invested at each rate, the following calculations must be performed:
1500 x 0.05 + 500 x 0.04 + 1000 x 0.03 = 75 + 20 + 30 = 125
1600 x 0.05 + 600 x 0.04 + 800 x 0.03 = 80 + 24 + 24 = 128
1700 x 0.05 + 700 x 0.04 + 600 x 0.03 = 85 + 28 + 18 = 131
Therefore, Elena invested $ 1,700 at 5%, $ 700 at 4%, and $ 600 at 3%
Answer:
Try 458.96 (round if needed)
Step-by-step explanation:
First you find the volume of the cone. (pi*radius^2*h/3)
Then you find the volume of a cylinder. (pi*radius^2*h) add these two up.
You would have to subtract 12.5 and 8.5 to get the height of the cone.
Also you would have to subtract 6 inches off of your total.
(Sorry If this explanation sucked.)
answer:
5.002 inches
step-by-step explanation:
- find the diameter of the circle
- the diameter is the side length of the square since the sides of it are touching the circle
c = 2πr
- c stands for circumference
- π stands for pi (or 3.14)
- r stands for radius
- plug in the values given to find the diameter
c = 2πr
15.71 = 2(3.14)r
15.71 = 6.28r
r = 2.501 (rounded or estimated)
- now that we have the radius, we can find the diameter by multiplying by 2, since diameter is two times bigger than the radius
diameter = 5.002 (estimated)
- now, that will be the side length because the diameter = the side length
Square root of 48= Square root of 16 times 3= 4 Square root of three. The square root of 48 is an irrational number!
