1 - 4 / 7 = 3 / 7 ( It means that it is 3 / 7 of the aquarium left to fill with water )
5 / 6 L ------ 4 / 7
x L --------- 3 / 7
5 / 6 : x = 4/7 : 3/7
5 / 6 : x = 4 : 3
4 x = 3 * 5/6
4 x = 15/6
x = 15/6 : 4
x = 5/2 : 4 = 5/8 L
Answer:
Jacob needs 5/8 L more to fill the aquarium,
or 5/6 + 5/8 = 35/24 L ( in total ).

B. Bradley
Step-by-step explanation:
We know that Ellen can type 205 words in 5 minutes. To start comparing to the other students, we need to find out how many words she can type per minute. We can divide 205 by 5 to get our answer.
<u>Ellen can type 41 words per minute</u>. To find our answer we must find how many words per minute the other students can type. Lets start with the first and go down from there:
Alissa:
It can't be Alissa.
Bradley:
Your answer is B. Bradley
Answer:
see below
Step-by-step explanation:
Part 1: 5(2x - 4) = 30.
Distribute
10x -20 = 30
Add 20 to each side
10x-20+20 =30+20
10x = 50
Divide by 10
10x/10 = 50/10
x =5
Part 2: 5x + 3 - x + 2 = 41
Combine like terms
4x +5 = 41
Subtract 5 from each side
4x+5-5 = 41-5
4x = 36
Divide by 4
4x/4 = 36/4
x = 9
Answer:
the answer of the question is 1
Answer:
a) 25446.90 ft²
b) 101787.60 ft²
c) 407150.41 ft²
d) 2025πt²
Step-by-step explanation:
Data provided in the question:
Rate of spread radially = 45 feet per day
a) Radius of spread after 2 days
= 45 × 2
= 90 feet
Therefore,
Area affected = πr²
= π(90)²
= 25446.90 ft²
b) Radius of spread after 2 days
= 45 × 4
= 180 feet
Therefore,
Area affected = πr²
= π(180)²
= 101787.60 ft²
c) Radius of spread after 2 days
= 45 × 8
= 360 feet
Therefore,
Area affected = πr²
= π(360)²
= 407150.41 ft²
a) Radius of spread after t days
= 45 × t ft
Therefore,
Area affected = πr²
= π(45t)²
= 2025πt²
