Each square below represents one whole.
What percent is represented by the shaded area?

Answer:

1.

∠DCB is the half of the measure of ∠ACB as the angle bisector DC cut it in two equal parts.

2.

The incenter is the intersection of the angle bisectors.

All three angle bisectors lie inside the triangle, hence the incenter is always inside.

Step-by-step explanation:

m(x + n) = n

mx + mn = n

mx = n - mn

x = (n - mn)/m

x(a + b) = b(c - x)

ax + bx = bc - bx

ax + bx + bx = bc

x(a + b + b) = bc

x(a + 2b) = bc

x = bc/(a + 2b)

mx = n(m + x)

mx = mn+ nx

mx - nx = mn

x(m - n) = mn

x = mn/(m-n)

Explanation:

s = Sam's age right now

2s = the mother's age right now, since she is twice as old as Sam currently.

In 12 years time, Sam will be s+12 years old.

12 years ago from this current year, the mother was 2s-12 years old.

Since we're told these future and past ages line up, this means s+12 and 2s-12 are the same value

Set the expressions equal to one another and solve for s.

s+12 = 2s-12

s-2s = -12-12

-s = -24

s = 24

Sam is currently 24 years old.

His mother is currently 2s = 2*24 = 48 years old.

12 years ago, his mother was 2s-12 = 48-12 = 36 years old.

12 years from now, Sam will be s+12 = 24+12 = 36 years old.

Since we get 36 each time, this confirms we have the correct answers.

Answer:

n =[tex]\frac{5}{10}[/tex]

Step-by-step explanation:

Answer:

n= 2 and two thirds

Step-by-step:

this is the equation

3/10n=4/5

so to get n by itself, you multiply both sides by 10/3. I did 4/5 times 10/3 and I got 2/2/3, or two and two thirds

Answer:

its 10 tenths because 6 is closer to 10 than 0 and when you have double digits you always look at the second number so that would round to 10

Answer: -1.

Step-by-step explanation:

Answer:

I think the answer is -1 but im not 100% sure i might be incorrect

Answer:

K=24

B=21

Step-by-step explanation:

x+x-5=43

2x=48

x=24

K=24

B=21

Answer:

24

Step-by-step explanation:

So the only way I think would be possible to get the answer is if you divide 43 by 2 (since Bobbie and Kylie are 2 people) then subtract 5 to get the answer?

Answer:

The markup formula is as follows: markup = 100 * profit / cost .

Step-by-step explanation:

For example if your cost is $10.00 and you wish to markup that price by 40%, 100% + 40% = 140%. Multiply the $10.00 cost by 140% and get the retail price of $14.00.

How do you calculate a 45 markup?

Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage.

Answer:

x=-2

Step-by-step explanation:

5x+4=-6 so basically what you want to do is try to get x by itself

step 1 subtract 4 from each side

5x=-10

step 2 divide each side by 5

x=-2

Answer:

Wait like all of them or some? I think it's 3 and 4.

Step-by-step explanation:

You add the two negative (negative + negative =positive). 3 and 4 have an extra left over which makes one negative, unless I did that wrong

Answer: 3 and 4

Step-by-step explanation:

If it is an odd number of (-1)s then it is negative. if it is an even number of them then it is positive.

Answer: 12km

Step-by-step explanation:

To find the missing side you need to use the formula a^2 + b^2 = c^2 where C is your hypotenuse.

So your formula would be 4^2 + 3^2 = c^2 ...

16 + 9 = c^2

25 = c^2 so square root both sides. Your missing side is 5km and then add all sides together to find your perimeter.

Answer: 600 m/s^2

Step-by-step explanation:

Answer:

D. (2,-3)

Step-by-step explanation:

if you substitute 2 for the x value and -3 for the y value in both equations, it works out.

instead of y=3x-9 it would be -3=3(2)-9.

you solve and get -3=-3, so it's a solution.

and instead of y=-2x+1 it would be -3=2(2)+1. after solving it, you would get -3=-3 again, so it works for both equations.

Answer:

[tex]35[/tex]

Step-by-step explanation:

From the information given we can solve for x using the larger triangle

we know that the angle at the top is 45 degrees and the side opposite of it is 35, in other words we need to find the adjacent, or rather, x

Since we have angle, an opposite side, and we need the adjacent. The trig function we need to use is [tex]tan[/tex], the formula is

[tex]tan0[/tex][tex]=\frac{opposite}{adjacent}[/tex]

we need to rearrange this to solve for the adjacent

[tex]adjacent=\frac{opposite}{tan(0)}[/tex]

[tex]x=\frac{15}{tan(45)}[/tex]

[tex]x=35[/tex]
