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 :)

Answer:

(6, 10)

Step-by-step explanation:

Step 1: Substitute 2x-2 for ‘y’ in the first equation:

4x - (2x - 2)= 10

Step 2: Combine like terms

2x -2 =10

Step 3: Add 2 to both sides of the equation

2x = 12

Step 4: Divide both sides by 2

x= 6

Now substitute x=6 into any of the equations given, I chose the bottom one.

Step 5: Plug in x=6 and solve

y= 2(6) -2

y= 12-2

y= 10

Step 6: Write your answer as an ordered pair (x, y).

Answer:

#5 = option a (129.38 miles):

We are told that the cities are 17.25 inches apart, and that 2 inches equal 15 miles. First we have to divide 17.25 inches by 2 we end up with 8.62500 inches (not simplified yet). Next, we just take 8.62500 inches and multiply that with 15, which leaves us with 129.37500 inches. Then we just round that to the nearest hundredth which will give us 129.38 inches which means 129.38 miles as well!

#2 = option a (2.4 inches)

We know that bigger rectangle's length is 16 inch and that smaller rectangle's length is 3.2 inches. We just have to calculate the decrease of the length and we do that by dividing. We have to do 16 inches divided by 3.2 inches which equals 5. (You can double check that by multiplying 3.2 inches by 5 which would equal 16 inches) Now to find the width of the smaller rectangle, we just have to divide the width of the bigger rectangle, which is 12 inches, by 5 which would give us 2.4 inches!

#4 = ?

#6 = option c (7.2cm)

So basically I just did 25cm divided by 10cm which equals 2.5cm. (You can also do 25cm divided by 2.5cm to get 10cm if you want to double check). Then I just did 18cm divided by 2.5 cm which led me to the answer 7.2cm)

#3 = ?

Answer: A

Step-by-step explanation: 17.25/2=8.652

8.652*15=129...

rounded it would be equivalent to answer choice A.

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Step-by-step explanation:

Answer: Option A is the correct answer

Step-by-step explanation: I took the test and got it right

The total weight of the two animals is 1.19 x 10³ lbs. So the correct option is B.

Given approximate weights of the two animals are as:

1. 5.12 x 10² lbs

2. 6.8 x 10² lbs

We need to find the total weight of the two animals.

Step 1: Add the weights together:

5.12 x 10² lbs + 6.8 x 10² lbs

Step 2: Perform the addition:

(5.12 + 6.8) x 10² lbs

11.92 x 10² lbs

Step 3: Express the result in scientific notation with the correct number of significant digits:

The first number, 11.92, has three significant digits. To maintain three significant digits in the final answer, we can express it as 11.9 (rounding to the nearest tenth) and adjust the exponent accordingly:

11.9 x 10² lbs

This matches option 2 from your provided answers:

2. 1.19 x 10³ lbs.

So, the correct answer is: 1.19 x 10³ lbs.

Answer: 1/4

Step-by-step explanation:

Answer: Range and mean = 8 of both

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Answer:

Time = 1.27 x 10^1 minutes

Step-by-step explanation:

To calculate the approximate amount of time it takes for light to travel from the Sun to Mars, we can divide the distance between them by the speed of light.

Given:

Speed of light = 1.12 x 10^7 miles per minute

Distance between the Sun and Mars = 1.42 x 10^8 miles

Time = Distance / Speed

Time = (1.42 x 10^8 miles) / (1.12 x 10^7 miles per minute)

Time = (1.42 / 1.12) x 10^(8 - 7) minutes

Time = 1.27 x 10^1 minutes

Rounded to the nearest hundredth, the approximate amount of time for light to travel from the Sun to Mars is 12.70 minutes in scientific notation.
