Let the investment in first account be x and this account is earning 3% interest
So Interest on this account is 3% of x = 0.03x
So the investment in second account would be (7000-x) and this account is earning 7% interest
So the interest on this account is 7% of (7000-x) = 0.07*(7000-x)
Given that total interest for the year is $262
So we have
0.03x + 0.07(7000-x) = 262
0.03x - 0.07x + 0.07*7000 = 262
-0,04x + 490 = 262
-0.04x = 262-490
-0.04x = - 228
0.04x = 228x
x = 228/0.04
x = 5700
Therefore Investment in one account s 5700 and the investment in other account is 7000-5700 = 1300
Answer:
Data: (Cylinder)
h (height) = 8 cm
r (radius) = 5 cm
Adopting:
V (volume) = ?
Solving:(Cylinder volume)
Note: Now, let's find the volume of a hemisphere.
Data: (hemisphere volume)
V (volume) = ?
r (radius) = 5 cm
Adopting:
If: We know that the volume of a sphere is , but we have a hemisphere, so the formula will be half the volume of the hemisphere
Formula: (Volume of the hemisphere)
Solving:
Now, to find the total volume of the figure, add the values: (cylinder volume + hemisphere volume)
Volume of the figure = cylinder volume + hemisphere volume
Volume of the figure = 628 cm³ + 261.6 cm³
