3ab-2bc=12 solve for c

Answers

Answer 1

Answer: The answer is 3a/2 - 6/b = c.
How?- First you subtract from both sides and add 2bc to both sides, 3ab-12=2ab
Second you divide 2b to both sides, (3ab-12)/2b= c
Third, you just finish the solving, 3ab/2b-12/2b = 3a/2 -6/b

A family wants to have 4 children. Design and do a simulation to determine the probability that, if they do have 4 children, they will have two boys and two girls. (Hint: Use coins.)

Answers

Let B represent boy and G represent girl, Then sample space

BBBB, BBBG, BBGB, BGBB, GBBB, BBGG, BGBG, GBBG, BGGB, GBGB, GGBB, BGGG, GBGG, GGBG, GGGB, GGGG

Two boys and two girls appeared in 6 situations.

Therefore, P(6 boys and 6 girls) = 6/16 = 3/8

Answer:

Using B as the boy and G as the girl, sample space

GGBB, BGGG, GBGG, GGBG, GGGB, GGGG, BBBB, BBBG, BBGB, BGBB, GBBB, BBGG, BGBG, GBBG, BGGB, GBGB, GGGG

Six different scenarios featured two boys and two girls.

P(6 boys and 6 girls) = 6/16 = 3/8 as a result.

Ind the slope of the line passing through the given points, when possible. (If an answer Js undefined, enter UNDEFINED. ) (-1,-15) and (6,-15)

Answers

Answer:

slope = 0

Step-by-step explanation:

calculate the slope m using the slope formula

m = $(y_(2)-y_(1) )/(x_(2)-x_(1) )$

let (x₁, y₁ ) = (- 1, - 15 ) and (x₂, y₂ ) = (6, - 15 )

substitute these values into the formula for m

m = $(-15-(-15))/(6-(-1))$ = $(-15+15)/(6+1)$ = $(0)/(7)$ = 0

in a circle graph above you can see that 47 percent of the companys monthly income is used to pay the owners personal salary if the amount of the owners personal salary was 2,176.10 this month what was the companys total income this month

Answers

the first thing you have to do is to divide the personal income by the percen it takes up

2,176.10/47=46.3

that means that 46.3 is 1% of the whole, so if we multiply it by 100 you will get the whole

46.3*100=4630

so the answer is

4,630

A model rocket is launched from a roof into a large field. The path of the rocket can be modeled by the equation y = -0.06x^2 + 10.1x + 5, where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground. How far horizontally from its starting point will the rocket land?

Answers

Answer:

The horizontal distance from the starting point when rocket lands is:

168.83 meters.

Step-by-step explanation:

We are given a function that models the height of the rocket when it is 'x' meters away from the starting point.

The function is:

$y=-0.06x^2+10.1x+5$

Now we are asked to find the horizontal distance from the starting point when the rocket will land.

i.e. we are asked to find 'x' ; when y=0

i.e.

Let y=0

$-0.06x^2+1.01x+5=0\n\ni.e.\n\n6x^2-1010x-500=0$

on solving the quadratic equation we obtain:

$x=-0.49360\ and\ x=(125)/(6)=168.83$

As the distance can't be negative.

Hence, the viable solution is:

x=168.83

Hello,

y=-0.06x²+10.1x+5
==>6x²-1010x-500=0
Δ=1010²+4*6*500=1032100=(1015,92...)²
x=(1010-1015.92...)/12 <0 exclude
or x=(1010+1015.92..)/12=168.826935... (m)
