Answer:
H. 3 units
Step-by-step explanation:
In order to answer this question, we have to apply the formula for the sphere volume. The formula is:
Plugging the given number into V, we calculate that:
If π=3.14, the radius is:
r ≈ 3 units.
Answer:
3.4 x 10^4
Step-by-step explanation:
1.6 x 10^4 - 5 x 10^4 = -3.4 x 10^4
5 x 10^4 - 1.6 x 10^4 = 3.4 x 10^4
Answer:
18 units
Step-by-step explanation:
So let's list out the sides.
for the first square let's just call them x
for the second square then they would be x+5 and x-3
So let's write out their areas we will cal the area of the first one z
x*x = z
(x+5)*(x-3) = z+21
since z = x^2 we can set up the second equation as a quadratic.
(x+5)*(x-3) = x^2 + 21
x^2 - 3x + 5x - 15 = x^2 + 21
But look, the x^2s cancel out
2x - 15 = 21
2x = 36
x = 18
Test it out and see if it fits the description, And if you don't understand anything just let me know so I can explain more.
Answer:
Step-by-step explanation:
Total weight of aluminum cans that Pete collected for recycling is 47 pounds.
Total weight of aluminum cans that Jo collected for recycling is 52 pounds.
They can get $0.21 per pound for the cans. Therefore,
The total amount that Pete will get for collecting 47 pounds of aluminum would be
0.21 × 47 = $9.87
The total amount that Jo will get for collecting 52 pounds of aluminum would be
0.21 × 52 = $10.92
The total amount of money that they would get is
9.87 + 10.92 = $20.79
Answer:
B. 1.55 x 106
Step-by-step explanation:
This is an example of the distributive property. In order to turn it back to the regular form, you need to do this:
3.40
-
1.85
--------
1.55
Don't forget to put the 106!
3.40
-
1.85
--------
1.55 x 106
You can do it in both forms and get the same answer. It depends on what the question asks for or whichever form you like best/you think is the easiest.
