Answer:

C

Step-by-step explanation:

Two angle are side to be compliment if there sum is 90°

<B + <A = 90°

<B = 90° - <A

<B = 90° - 40°

<B = 50°

Two angle are side to be compliment if there sum is 180°

<B + <C = 180°

<C = 180° - <B

<C = 180° - 50°

<C = 130°

m<B + m<C = 50° + 130° = 180°

Answer:

c

Step-by-step explanation:

Two angle are side to be compliment if there sum is 90°

<B + <A = 90°

<B = 90° - <A

<B = 90° - 40°

<B = 50°

Two angle are side to be compliment if there sum is 180°

<B + <C = 180°

<C = 180° - <B

<C = 180° - 50°

<C = 130°

m<B + m<C = 50° + 130° = 180°

an algebra teacher drove by a farmyard full of chickens and pigs.the teacher happened to notice that there were a totals of 100
LiRa [457]
I'll be honest, this is a pretty interesting question. I've never seen anything like it before!

We can start off by making equations with the given. If there are 100 heads, that means that the total number of chickens and pigs combined is 100. Thus, we can form our first equation:

p + c = 100
('p' represents number of pigs, and 'c' represents number of chickens)

We also know that there are 270 legs total. Since chickens have 2 and pigs have 4, we can make the following equation:
2c + 4p = 270

I suppose the quickest way to solve for this equation is to use the subtraction method. Put the equations on top of each other:

2c + 4p = 270
c + p = 100
___________
Multiply the bottom equation by -2;

2c + 4p = 270
-2c -2p = 100
____________
"Add" these two equations together:

2c + 4p = 270
-2c -2p = -200
___________
2p = 70

Divide both sides by 2:
p = 35

Ah, finally. Now that we know that there are 35 pigs, input this variable into the first equation to find the number of chickens:

c + 35 = 100
Subtract:
c = 65

There are 35 pigs and 65 chickens

suppose a chord of a circle is 18 in. long and is 40 in. from the center. Find the length of the radius.
drek231 [11]
Using the Pythagorean Theorem,
radius^2 = 40^2 + 9^2
radius^2 = 1,600 + 81
radius^2 = 1,681
radius = 41

Write the slope-interceptiin form of the equation 17=y+4x
erastova [34]

Answer:

Step-by-step explanation:

slope intercept form is y = mx + b

17 = y + 4x....we have to get y on one side and everything else on the other side.....so the easiest way would be to subtract 4x from both sides

17 - 4x = y + 4x - 4x....combine like terms

17 - 4x = y...rearrange

y = -4x + 17 <===== slope intercept form
