ANSWER
Find out the how much does it grow in 8 weeks
To proof
As given
A coral reef grows 0.17 m every week.
now for the 8 weeks
coral reef grows in the 8 weeks = 8× 0.17
= 1.36 m
As
1 meter = 1000 millimeter
To convert growth of coral reef in the millimeter
= 1.36 × 1000
= 1360 millimeter
Hence 1360 millimeter be the coral reef grows in 8 weeks
It means "approximately" instead of "equal to"
Answer:
5n + 25q = 200 - - - (1)
n = 5q - - - (2)
q = 40
n = 5(40) = 200
Step-by-step explanation:
Number of Nickels = n
Number of Quarters = q
$2.00 = $2 * 100 = 200 cent
Nickel = 5 cent
Quarter = 25 cent
5n + 25q = 200 - - - (1)
n = 5q - - - (2)
5(5q) + 25q = 200
25q + 25q = 200
50q = 200
q = 200/5
q = 40
n = 5(40) = 200
Answer:
<u>5/8</u>
Step-by-step explanation:
So, let's do the first one first.
You want to make the fraction have the same denominator (bottom number). So, in this case, we have 3/8 and 3/4. If we want them to have the same bottom number, we keep 3/8 how it is, and multiply 2/2 by the 3/4 to get 6/8. So, now we have 3/8 + 6/8. 3/8 + 6/8 = 9/8.
Now, we have 1/3 + 1/6. So, we are going to do the same thing, keep the 1/6, and multiply 1/3 by 2/2, so that the bottom number is equal to the other fraction's bottom number. So, 1/3 x 2/2 = 2/6. Now, we have the equation 2/6 + 1/6. 2/6 + 1/6 = 3/6.
Now, we have this final equation: 9/8 - 3/6. So, now we need to find the denominator that both of them can deal with. So, in this case, we can do 24.
9/8 x 3/3 = 27/24
3/6 x 4/4 = 12/24
Now, we subtract:
27/24
- 12/24
_______
15/24.
Now, we simplify.
15 divided by 3 = 5.
24 divided by 3 = 8
So, <u>5/8</u> is our final answer.
