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

Answer:
3 3/4
Step-by-step explanation:
Each block is worth 0.5 cm (1/2)
One note - NEVER FORGET THE UNITS
L - 5 blocks (5 blocks × 0.5cm = 2.5cm)
W - 2 blocks (2 blocks × 0.5cm = 1cm)
H - 3 blocks (3 blocks × 0.5cm = 1.5cm)
Formula for Volume:
V = L × W × H
V = 2.5cm × 1cm × 1.5cm = 3.75cm (fraction can be 3 3/4)

2r-5/4 = 58
I don’t understand what to do next
Hi
The aim of an equation is to have the letter on one side and a value to the pther side of the equal sign.
For achieving this goal, I can use all operation I know and all quantities I want as long as I do it to each side in the same time. I will make apparent operation in bold.
So :
2r - 5/4 = 58
if I want 2r to be alone, I need to get rid of -5/4
The best way to do that is to add 5/4 to each side as -5/4 + 5/4 = 0
so
2r -5/4 +5/4 = 58 +5/4
2r +0 = 58 +5/4
now we have :
2r = 58+5/4
I will caculate the value of 58 +5/4
best way to do that is to convert 58 into a fraction . as 58 *4 = 232 so 58 = 232/4
so now we have :
2r = 232/4 +5/4
2r = 237/4
2r = 59.25
Now we have " 2r " , but my aim is to have only one " r" . So we divide by "2" on each side :
2r /2 = 59.25 /2
r =29.625
If I want to check my result, I exchange the letter by the value I found.
2 ( 29.625 ) - 5/4 = 59.25 - 5/4 = 59.25 - 1.25 = 58
as 58 is the value given in line one for 2r - 5/4 , so my result is correct.
Answer:
r = 118.5
Explanation:
Given expression:
\(\sf \dfrac{2r-5}{4} = 58\)
Multiply Both sides by 4
\(\sf \dfrac{2r-5}{4} \times 4 = 58\times 4\)
Doing so gives:
\(\sf 2r-5 = 232\)
Add 5 on both sides
\(\sf 2r-5+5 = 232 + 5\)
Simplify following
\(\sf 2r = 237\)
Dividing Both sides by 2
\(\sf r = 118.5\)

1 Mile in distance from the campsite to the pond.
If there are 4 squares that seperate the campsite from the pond, that is 1/4's a mile each.
1/4 + 1/4 + 1/4 + 1/4 = 4/4 (1 mile.)
You add the numerators together (In this case the numerator is the 1).
You do NOT add the denominators together (And in this case the denominator is 4).

Answer:
16b^4-9
Step-by-step explanation:
Factoring gives us 16b^4+12b^2-12^2-9. Simplifying gives us the answer which is 16b^4-9
Answer:
\(16b^4-9\)
Step-by-step explanation:
When multiplying binomials, we can use a method called FOIL (First-Outside-Inside-Last).
For \((t_1+t_2)(t_3+t_4)\), let:
\(t_1\implies \text{First Term},\\t_2\implies \text{Second Term},\\t_3\implies \text{Third Term},\\t_4\implies \text{Fourth Term}\)
In the FOIL method, the steps go:
\(\text{\textbf{F}irst: Multiply the first and third terms (first term of each binomial)},\\\text{\textbf{O}utside: Multiply the first and fourth terms},\\\text{\textbf{I}nside: Multiply the second and third terms},\\\text{\textbf{L}ast: Multiply the second and fourth terms (last term of each binomial) }\)
Given \((4b^2+3)(4b^2-3)\), we have:
\(\text{First: }4b^2\cdot 4b^2,\\\text{Outside: }4b^2\cdot -3,\\\text{Inside: }3\cdot 4b^2,\\\text{Last: }3\cdot -3,\\\rightarrow 16b^4-12b^2+12b^2-9\)
Combine like terms:
\(\boxed{16b^4-9}\)

Question
Today, John ran 15 miles in 2 hours and 30 minutes. He wants to represent the relationship between the distance he ran, in miles, and the time, in hours, as proportional in order to examine his times at various distances. Write an equation that John can use to represent a proportional relationship between distance, d , in miles, and time, t , in hours.
Answer:
d = 6t
Step-by-step explanation:
Firstly, lets change the 2 hours and 30 minutes to 2.5 hours, you could devide the time in minutes by 60 to get that number 2[hours]+()[minutes to hours] = 2.5Hours. Anyway, John ran 15 miles in 2.5 hours which means he ran (15÷2.5) in one hour which is equal to 6miles per hour. That means if you multiply the hours he ran by 6 you will get the miles he ran. So the answer would be:
d = 6t

Find radical A and B
Answer:
a = 5 and b =6
Step-by-step explanation:
rationalize the denominator by multiplying the numerator and the denominator of the fraction by the inverse of the denominator: 2 - sqrt5.
((40 + 17 sqrt5) * (2-sqrt5)) / ((2+sqrt5) * (2-sqrt5)) = -5 - (6*sqrt5) / -1
multiply the numerator and the denominator by -1: 5 + 6sqrt5
a = 5 and b = 6
The required value of A = 5 and B = 6
\(\frac{40+17\sqrt{5} }{2+\sqrt{5} }= a+b\sqrt{5}\)
A = ? B=?
Fraction is defined as the number of composition constitute the Whole.
\(\frac{40+17\sqrt{5} }{2+\sqrt{5} }= a+b\sqrt{5}\)
multiply numerator and denominator by 2-√5
(40+17√5)(2-√5) / (2+√5)(2-√5) = a+b√5
80-40√5+34√5-85/4-5 = a+b√5
5+6 = a+b√5
Thus, the required value of A = 5, B = 6

If the circumference of a circle is 11 pi, what is the area?
Answer:
So our answer in pi form is 30.25π
Step-by-step explanation:
The circumference of a circle is given by the formulas :
\(2\pi r\) or \(\pi d\) where r is radius and d is the diameter
Since
11π = 2πr
We can solve for r to use it in the area of a circle formula:
\(\frac{11\pi }{2\pi } = r\)
r = 5.5
The area of a circle is given by the formula:
\(\pi r^{2}\) where r is the radius/.
Since we found r we can find the area:
π(5.5)² = 30.25π
So our answer in pi form is 30.25π
Answer:
As you have not specified the format in which to give the answer, I am giving three ways of writing it:
\(\sf 30.25 \pi \ units^2\)
\(\sf \dfrac{121}{4} \pi \ units^2\)
95.03 units² (nearest hundredth)
Step-by-step explanation:
Formulae
Circumference of a circle = 2πrArea of a circle = πr²(where r is the radius)
Given:
circumference = 11πTherefore, use the given value and the circumference equation to find the radius:
⇒ circumference = 11π
⇒ 2πr = 11π
⇒ 2r = 11
⇒ r = 5.5
Now we have found the radius, simply substitute this into the equation for area of circle:
⇒ area of a circle = πr²
= π5.5²
= 30.25π units²

4 liters of 2% milk contains 8% cholesterol. A container of skim milk contains 2% cholesterol. How many liters of skim milk need to be added to the 4 liters of 2% milk to create a mixture with 4% cholesterol?
To solve this problem, we can set up an equation based on the amount of cholesterol in the mixture.
Let's assume that x liters of skim milk need to be added to the 4 liters of 2% milk.
The amount of cholesterol in the 4 liters of 2% milk is 8% of 4 liters, which can be calculated as (8/100) * 4 = 0.32 liters of cholesterol.
The amount of cholesterol in the x liters of skim milk is 2% of x liters, which can be calculated as (2/100) * x = 0.02x liters of cholesterol.
The total amount of cholesterol in the mixture is the sum of the cholesterol in the 2% milk and the skim milk, which should be equal to 4% of the total volume of the mixture. So, we have:
0.32 + 0.02x = (4/100) * (4 + x)
Simplifying the equation:
0.32 + 0.02x = 0.04(4 + x)
0.32 + 0.02x = 0.16 + 0.04x
0.02x - 0.04x = 0.16 - 0.32
-0.02x = -0.16
Dividing both sides by -0.02:
x = (-0.16) / (-0.02)
x = 8
Therefore, 8 liters of skim milk need to be added to the 4 liters of 2% milk to create a mixture with 4% cholesterol.
To solve this problem, we can use the following equation:
4+x4×8+x×2=4
This equation represents the ratio of the total cholesterol to the total volume of the mixture. The numerator is the sum of the cholesterol from the 2% milk and the skim milk, and the denominator is the sum of the volumes of the 2% milk and the skim milk. The equation is equal to 4 because we want the mixture to have 4% cholesterol.
To find x, we can simplify and solve for x:
4+x32+2x=4
32+2x=16+4x
16=2x
x=8
Therefore, we need to add 8 liters of skim milk to the 4 liters of 2% milk to create a mixture with 4% cholesterol.
