Answer:
222.86
Step-by-step explanation:
<h2><u>in order to solve this question you can create an equation :</u></h2>
35% * x = 78
where x is the original amount
in order to get x , you have to say :
78/ 35% = x
hence x = 222.8571...
to 2dp = 222.86
The right answer is E because you have to multiply all those numbers and when you do you get 3,000
Answer: However, in real life it depends on the shape of the actual presents. If two sheets are used for the 2 presents. There should be enough left from those sheets to use for the third present. (They should be taped together.)
Step-by-step explanation: 6/3 then 3 over 8 ––> 3/8
6/ 27/8
= 6/1 / divide 27/8
= 6^2 /1 x 8/27 ^9 (^) –––> this mean square root of 2 or 9
6 cancels and 27 cancel
= 16/9
=1 7/9
However you will still need to buy 2 sheets
Answer:
1920π
Step-by-step explanation:
First, you need to find the volume of the statue in terms of pi.
Volume of cylinder formula:
V=πr²h
V=π4²15
V=π16×15
V=240π
Then, you need to find the mass of the statue.
Mass:
Mass= density × volume
Mass=20×240π
Mass=4800π
Now, you need to find the volume. Since the sand has to weigh the same as the statue, the mass is going to stay the same. To find the volume you need to do:
V=mass of sand/density
V=4800π/2.5
That gives you your answer:
1920π
Note: I had to do the exact same problem on Khan Academy. This is right.
Answer:
Need help with using the graph to find the numbers
Assignment is about evaluating composition of functions from graphs anything helps
