Answer:
7800 units per year
Step-by-step explanation:
The increase over 5 years is ...
89,000 -50,000 = 39,000 . . . . units
Then the increase per year is ...
(39,000 units)/(5 years) = 7,800 units/year
Answer:
The diameter is: d = 5m
Step-by-step explanation:
We know that
Circumference of Circle = 2πr
Given that
The circumference of a circle = 5π
so the equation becomes
Circumference of Circle = 2πr
5π = 2πr
2πr = 5π
r = 5π/2π
r = 5/2 m
As we know that:
The diameter is twice the radius. i.e. d = 2r
Thus, the diameter is:
d = 2(5/2)
= 5 m
Therefore, the diameter is: d = 5m
You can add them like this:
so if 156 + 213 + 109 was the equation then you would
first put them in order from biggest to smallest
213
156
+109
-----------
then add:
¹ ← ←
213 ↑
156 ↑
+109 ↑
---------↑ ( carry the 10 )
478 (add the ¹ )
then you get the answer 478!
hope that helps :)
Answer:
$25
Step-by-step explanation:
500 mins = $35 (fixed + per minute charge)
1500 mins = $55 (fixed + per minute charge)
If we let per minute charge be "m"
and
let fixed charge be "f"
we can write 2 equations as:
35 = 500m + f
and
55 = 1500m + f
Now,
We re-write both equations in terms of f and equate both expressions:
f = 35 - 500m
and
f = 55 - 1500m
Equating:
35 - 500m = 55 - 1500m
-500m + 1500m = 55 - 35
1000m = 20
m = 20/1000
m = 0.02
Now we find f, what we are looking for:
f = 35 - 500m
f = 35 - 500(0.02)
f = 25
So, the fixed charge is $25
To answer this you would need to first find out what 3/8 of the 5/9 would be. 3/8 would be the amount that remains after five eights were accounted for. The question says it is 5/9 of the remaining, and 3/8 of the total would be what remains. Multiply 3/8 by 5/9 to get 5/24. This represents the part that would be green. Then I added the original 5/8 for blueand 5/24 for green. The amount is 20/24, or 5/6. This represents the part that is green or blue. 1/6 would be the other color which is red. To find the total, you would solve 1/6x =48. To solve this divide 48 by 1/6. Keep change and invert your division problem. It would be 48×6. The answer is 288 total votes. You said check your work by multiplying 5/8 by 288. You get 180. 288-180=108. Multiply 5/9 by 108 to get 60. 108-60 is 48!!!
