There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)
A contractor is building the base of a circular fountain. On the blueprint, the base of the fountain has a diameter of 18 centimeters. The blueprint has a scale of three centimeters to four feet. What will be the actual ares of the base of the fountain, in square feet, after it is built? Round your answer to the nearest tenth of a square foot.
Answer:
452.4 square feet
Finding the diameter:
Since there are 3 centimeters for every 4 feet, we need to divide 18 by 3
18 ÷ 3 = 6 which means the ratio is scaled up by 6 so we multiply 4 by 6
4 · 6 = 24 that means that the diameter of the base of the fountain is 24 feet
Finding the area:
Since the area of a circle is πr² we need to divide the diameter by 2 to get the radius(r)
24 ÷ 2 = 12 now we need to square 12 (which is multiplying it to itself ex. 5² is 5 · 5)
12 · 12 = 144 now we multiply it by π
π · 144 ≈ 452.38934 lastly we round it
452.4 square feet
Hope this helps!

A girl is half as old as her sister and is also two years younger than her brother. If the sum of the three children's ages is 34 years, what is the product of their ages?
ASAP pls
Answer:
1280
Step-by-step explanation:
Let x represent the age of the girl then...
Brother: x+2
Sister: 2x
We can use this to set up an equation:
x+x+2+2x=34
Combine like terms
4x+2=34
Subtract 2 from both sides
4x=32
Divide both sides by 4
x=8 (girl)
x+2=10 (brother)
2x=16 (sister)
Now, we multiply these three numbers to get the product of their ages.
8(10)(16)=80(16)=1280

Good luck ! For future reference, the answer is y divided by x. So for the first one, 20/2 is 10, meaning your answer is 10. Hope this helps!
Answer:
1. 10
2. $12
3. 4
4. 19
5. 30
6. 18
7. 2
8. $42
Step-by-step explanation:
To get the answer, divide the y by the x. For example, I got 30 for number 5 because i did 240 (the y) divided by 8 (the x) which equals 30 and is the answer.

PLEASEEEE HELPP!!!! PLEASEE HELP NOW PLEASE!!
Answer:
7.19
Step-by-step explanation:
Answer
$7.20 if you round up. Not rounded is $7.198 or just $7.19
Step-by-step explanation
First, get original price which is $9 rounded.
Then, multiple by percent off which would be .20 or .2. Don't get this confused with 2% off which is .02.
After multiplying, you should get the answer of $1.80, this is 20% of $9.00. So if the product was 20% off, you would subtract. This gives you the final answer of $7.20

Sally’s bank account has $650 in it. Every week sally withdraws $50 to pay for her dog sitter. What is the maximum number of weeks tajar sally can withdraw the money so that there is at least $75 remaining in the account? Write and solve an inequality to find the solution, and graph the solution on a number line.
Pls help 10 pts for this due tmrw!!!
Answer:11
Step-by-step explanation:I think
answer: the maximum number of weeks Sally can remove $50 from the account and still have at least $75 is 11 weeks.
show my work :
Let W be the number of weeks Sally has been withdrawing money. The total in the account would be represented by 650-50W at any given time.
To remain over or equal to $75 the equation to solve is
650 - 50W >= 75
we need to get the variable on one side and the constants on the other so subtract 650 from each side...
-50W >= 75-650
-50W >= -575
Now we need to divide out the coefficient of the variable so divide both sides by -50. Note that multiplying or dividing an inequality by a negative reverses the inequality so...
W <= (-575)/(-50)
W <= 11.5
So in whole numbers the maximum number of weeks Sally can remove $50 from the account and still have at least $75 is 11 weeks.

Javier has a model of a cone with a radius of 3 inches and a height of 10 inches. Javier increased his model’s volume by doubling its radius and height. What is the volume of the larger cone in cubic inches?
Answer: 113.04 cubic inches!
Step-by-step explanation:
The volume of the larger cone is 113.04 cubic inches. This can be found by using the formula for the volume of a cone: V = (πr2h)/3. Plugging in the new radius (6 inches) and height (20 inches) gives us V = (3.14*62*20)/3 = 113.04.

A cylinder has a radius of 14 inches and a height of 10 inches. A rectangular prism has
square bases with side lengths of 8 inches. The two figures have the same surface
area. What is the approximate height of the rectangular prism?
Answer:
61.973
Step-by-step explanation:
let the unknow side be x
surf of prism = 2*(8*8+8x+8x) = 2*(64+16x) = 128+ 32x
again, surface of cylinder = 2pi*r*(r+h) = 2 * pi * 14 * (14+10) = 672pi
now solve for x, when
128+32x = 672pi

Marcus needs 12 cups of edible flowers to make the breakfast mixture to feed the zoo's emperor tamarin monkey troop for the week. The number of cups of edible flowers the zoo has in storage is represented by the expression 1.875c−(c+0.5d). If c=25 and d=20, does Marcus have enough edible flowers to make the breakfast mixture for the emperor tamarin monkeys?
No, because 1.875(25)-((25)+0.5(20))=11.875, which is less than 12.
No, because 1.875(25)−((25)+0.5(25))=9.375, which is less than 12.
No, because 1.875(20)−((25)+0.5(20))=2.5, which is less than 12.
No, because 1.875(20)−((20)+0.5(25))=5, which is less than 12.
Answer:
No, because 1.875(25)-((25)+0.5(20))=11.875, which is less than 12.
Step-by-step explanation:
c = 25 d = 20
1.875(25) - (25+0.5*20) =
46.875 - 35 =
11.875
