Answer:

c=100%-25%=75%

=75/100=0.75

Answer:

72 alligators, 128 turtles

Step-by-step explanation:

When you put the words into the form of an equation, with a being alligators, you get

3a-16=200

So you have to do 'letters left numbers right'. This gives you

3a=216

Now you have to divide. 216 divided by 3 equals 72. So there are 72 alligators. 200 minus 72 equals 128, so there are 128 turtles

Answer:

the answer is there are 162 alligators and 38 turtles

Step-by-step explanation: See so 54X3= 162

                                                  and 54-16=38

                                               then 162+38=200

Answer:

0/27

Step-by-step explanation:

Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there are 22 numbers to the right of the decimal point, place the decimal number over 102102 (100)(100). Next, add the whole number to the left of the decimal.

B) False

Step-by-step explanation:

Theres no way that you can make then equivalent because if you subtract the constant and the variables it'll be something like (#) = 0.

Answer:

x = 3

Step-by-step explanation:

The two triangles at the left have the same angles and share a side, so they are congruent.  Therefore, the vertical side is also 6x−2.

Using the same logic, the two triangles on the right have the same angles and share a side, so they are congruent.  Therefore, the vertical side is also 9x−11.

So:

6x − 2 = 9x − 11

9 = 3x

x = 3

Answer:

6 x 2 +1

Step-by-step explanation:

13

6 x 2 = 12

13-12 = 1

6 x 2 + 1 = 13

Answer:

5= 34-x

Step-by-step explanation:

Answer: x=-4. So C

Step-by-step explanation:

2x-1=-9

add 1 on both sides

2x=-8

divide 2 on both sides to isolate the variable

x=-4

Given:

After 4 minutes of reading, Aaron was on page 14 of his book.

After 8 minutes he was on page 20.

To find:

The equation that models the page number, y in terms of minutes x.

Step-by-step explanation:

Let  y be the page number after x minutes of reading.

After 4 minutes of reading, Aaron was on page 14 of his book. So, the line must be passes through (4,14).

After 8 minutes he was on page 20. So, the line must be passes through (8,20).

The equation of line which passes through two points is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

The required line passes through (4,14) and (8,20), so the equation is

[tex]y-14=\dfrac{20-14}{8-4}(x-4)[/tex]

[tex]y-14=\dfrac{6}{4}(x-4)[/tex]

[tex]y-14=1.5(x-4)[/tex]

[tex]y-14=1.5x-6[/tex]

Add 14 on both sides.

[tex]y-14+14=1.5x-6+14[/tex]

[tex]y=1.5x+8[/tex]

Therefore, the correct option is B.

Answer:

sqrt(r^2/ Gt) =d

Step-by-step explanation:

r^2/d^2 = Gt

Multiply each side by d^2

r^2/d^2  * d^2  = Gt * d^2

r^2 = Gt d^2

Divide each side by Gt

r^2/ Gt = Gt d^2 / Gt

r^2/ Gt =  d^2

Take the square root of each side

sqrt(r^2/ Gt) = sqrt( d^2 )

sqrt(r^2/ Gt) =d

Answer:

[tex]\sqrt{41}[/tex]

Step-by-step explanation:

Hello!

In order to answer this question, we need to use the distance formula.

[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The order of these points can be chosen in any way, but they need to be done in the same pair (just like when you find the slope).

For this problem, let's let the J pair be the [tex]x_2, y_2[/tex] pair and the K pair be the [tex]x_1,y_1[/tex] pair.

[tex]x_2[/tex] = -3

[tex]x_1[/tex] = 2

[tex]y_2[/tex] = 2

[tex]y_1[/tex] = -2

Now, let's plug these points in.

[tex]\sqrt{(-3-2)^2+(2-(-2))^2}[/tex]

[tex]\sqrt{(-3-2)^2+(2+2)^2}[/tex]

[tex]\sqrt{(-5)^2+(4)^2}[/tex]

[tex]\sqrt{25+16}[/tex]

[tex]\sqrt{41}[/tex]

Thus, the distance between points (-3,2) and (2,-2) is [tex]\sqrt{41}[/tex].
