Answer:

x = $\frac{12y - 74}{7}$

Step-by-step explanation:

12y = 75 + 5x + 2x - 1

combine like terms:

12y = 74 + 7x

subtract 74 from both sides:

7x = 12y - 74

divide both sides by 7:

x = $\frac{12y - 74}{7}$

Answer:

x = 7/12

Step-by-step explanation:

So we are trying to put it in y = mx + b form

So first we just have to collect like terms

12y = 74 + 7x

Divide both sides by 12

y = 7/12x + 74/12

We have to reduce to its lowest terms

y = 7/12x + 37/6

If C is the MIDPOINT of BD, and BD equals 12, then what does CD equal?
AD = AC+CD, so you only need to find length of CD and add length of AC (which you already have) to it.
Hope this helps

TV studio has brought in 9 boy kittens and 6 girl kittens for a cat food commercial. The director is going to choose 9 of these

Amanda [17]

Answer:

probability = 0.2517

Step-by-step explanation:

given data

boy kittens = 9

girl kittens = 6

choose kittens at random = 9

solution

total kitten are = 9 + 6 = 15

first we get here total no of probability that is

n(s) = 15 C 9

n(s) = $\frac{15!}{9!(15-9)!}$

n(s) =5005

and

total way to chose 5 boy kittens is = 9 C 3

n(3) = $\frac{9!}{3!(9-3)!}$

n(3) = 84

and

total way to chose 4 girl kittens is = 6 C 4

n(4) = $\frac{6!}{4!(6-4)!}$

n(4) = 15

total way to chose 5 boy kittens and 4 girl kittens is

total way = 84 ×15 = 1260

so probability that the director chooses 5 boy kittens and 4 girl kittens is

probability = $\frac{1260}{5005}$

probability = 0.2517

The volume of the cylinder is C, 753.6 mm³.

To find the volume of the cylinder, in cubic millimeters, we must first convert all of the measurements into millimeters. The only measurement that isn't in millimeters is height, and 1.5 centimeters is equal to 15 millimeters.

Now, we need to find the volume. The volume can be found by doing πr²h. Now we can substitute values and solve.

V = πr²h

V = 3.14(4)²(15)

Simplifying this, we get that V = 753.6, meaning that our answer is C, 753.6 mm³.
