Answer:

There were 650 rabbits last year

The percentage of a quantity can be found by first changing the percent into a fraction and then multiplying it to the value of that quantity. Last year the number of rabbits was 150.

A percentage is a value that indicates the hundredth part of any quantity.

To convert percentage into a fraction it is divided by 100.

Given that,

The population of rabbit this year is 300.

The percentage of the population with respect to the last year is 200%.

Suppose the population of rabbits last year was P.

Then as per the question, following expression can be written,

200% of N = 300

⇒ (200 / 100) × N = 300

⇒ 2N = 300

⇒ N = 150

Hence, the population of the rabbits last year was 150.

Answer:

Start by getting everything on the same side of the equals sign and then set it equal to 0.  .  Factor out the common tan^2x like this: .  Now we have 2 separate equations to solve:  and sinx = 0.  Now we have to figure out where tan^2 is 0 between 0 and 2pi.  If we include 2pi, the solutions for that equation are .  You can test those out on your calculator just to be sure.  There's only one value of x for the next equation.  The only place between 0 and 2pi where the sin x = 1 is at x = .  And there you go!

Step-by-step explanation:

Answer: A

Step-by-step explanation:

The equation option 3rd is correct option.

An expression or a statement that comprises two algebraic expressions with the same value and are separated by an equal symbol in between them.

Given that, four equation,

5 = 3x/2 - 8

Adding 8 to both sides,

5 + 8 = 3x/2 - 8 + 8

13 = 3x/2

Multiplying by 2 to both sides,

13*2 = 3x/2*2

26 = 3x

x = 26/3

Hence, equation 3rd is the correct answer.

Answer:

There are 20 potatoes in each bag.

Step-by-step explanation:

There are 12 in a dozen. 10 dozens equal 120.

120 ÷ 6 = 20.

20 potatoes in each bag.

Hope this helped!

Answer:

there are 20 potatoes in each bag.

Step-by-step explanation:

One dozen is equal to 12, so you have to multiply 12 by 10 to find the number of potatoes Julio's dad bought.

12 x 10 = 120

after finding the number of potatoes bought, you have to divide the number of potatoes by the number of bags:

120 : 6 = 20

x = 40 degrees

Step-by-step explanation:

The line at the angle adds up to 180 degrees because it is straight, so we have the equation 100 + 2x = 180

Equation:

100 + 2x = 180

2x = 80

Answer:

M<GEF=30

M<DEF=40

Step-by-step explanation:

First you want to solve for x. to do that you put both of the equations together and make it equal to 70 since M<GED=70. so you would get 2x+10+5x-10=70.

when you solve that you get x=10. next you substitute x with 10 in the other equations to solve for the unknown measure angle. So M<GEF=2(10)+10 and M<DEF=5(10)-10. When you solve that you get M<GEF=30 and M<DEF=40. you can check this by adding them together and they add up to 70 which is the M<=GED.
