Answer:
Step-by-step explanation:
a) together, they all drink about 2,090 glasses of water in one day. (418 * 5 = 2,090).
b) 2,090 * 7 (7 days in 1 week) = They drink about 14,630 glasses of water in one week.
c) 14,630 * 4 (4 weeks in 1 month) = About 58,520 glasses of water in one month.
d) 1,000,000/58,520 ≈ 17. It would take all of the students about 17 months to drink 1,000,000 glasses of water.
Hope that helps!
Answer:
The total change in value of her shares is $300
Step-by-step explanation:
Given that each share went up by $10 and she has 30 shares then the total change in the value of her shares is the product of the change in the price of each share and the total number of shares she has
= $10 * 30
= $300
Answer:
30
Step-by-step explanation:
Perimiter is the length of each side added up. We don't know the side lengths, but we can find it.
It tells us the volume and height, and we use the side lengths to find volume, so lets use that. I'm not sure how you have learned how to find the area of a pentagon, but I am going to use the formula google shows. I am going to use x for the side length
A = sqrt(25+10sqrt(5))x^2/4
Now, for any right prism you take the volume of you get the area of the base and multiply it by the height So we can work that out to find the sides.
A*h = V
(sqrt(25+10sqrt(5))x^2/4)*14 = 840
(sqrt(25+10sqrt(5))x^2/4) = 60 (Divide both sides by 14)
sqrt(25+10sqrt(5))x^2 = 240 (Multiply both sides by 4)
x^2 = 34.874 (Divide both sides by sqrt(25+10sqrt(5))
x = 5.905 (square root of both sides)
Now we have the length of one side. Since there are five sides we multiply that by 5.
5 * 5.905 = 29.525 So it rounds up to 30.
Let me know if there is something you did not understand.
Answer:
- A matches with 5.
- B matches with 3.
- C matches with 2.
- D matches with 6.
- E matches with 4.
- F matches with 1.
Step-by-step explanation:
To find the inverse of a function 
, we let 
and then solve again for y.
For example, using 
, we will let 
, giving 
. This means that 
, and thus 
.
Using similar logic, we see that:
- A matches with 5.
- B matches with 3.
- C matches with 2.
- D matches with 6.
- E matches with 4.
- F matches with 1.
Answer:
false because you would multiply 5×the number of options so 5×4=20
