Answer:

EG is perpendicular to HF

Step-by-step explanation:

We know this because in order for two segments to be perpendicular there has to be a right angle. And there is a right angle therefore segment EG is perpendicular to segment HF

Answer:F is perpindicular to G

Step-by-step explanation: Well I think this because they both have angles but im kinda confused to this is just a guess

Answer:

100 bicycle

Step-by-step explanation:

Given the cost c in dollars of manufacturing x bicycles at a production plant expressed as C(x)=5x^2-1000x+63,500.

x is the number of bikes

To minimize the cost, dC/dx = 0

dC/dx = 10x - 1000

Since dC/dx = 0

0 = 10x - 1000

-10x = -1000

x = 1000/10

x = 100

Hence the number of bicycles that must be manufactured to minimize the cost is 100 bicycle

Answer:

4y-5xz has a degree of 2

Step-by-step explanation:

The degree of an expression the the largest degree of any of its terms.

The degree of a term is the sum of the exponents of the variables in that term.

4

y

=

4

y

1

has a degree of 1

5xz=5x1z1

has a degree of ( 1+1)=2

(5xz)

has a higher degree than

(4y)

Therefore the degree of the expression is the degree of

(5xz) , namely 2

Answer:

110

Step-by-step explanation:

y = 11/6x where x is in minutes

there are 60 minutes in an hour

plug in 60 as x

11/6 *60 = 11*10 = 110

Step-by-step explanation:

Answer:

x = -5, and y = -6

Step-by-step explanation:

Suppose that we have two equations:

A = B

and

C = D

combining the equations means that we will do:

First we multiply both whole equations by constants:

k*(A = B) ---> k*A = k*B

j*(C = D) ----> j*C = j*D

And then we "add" them:

k*A + j*C = k*B + j*D

Now we have the equations:

-x  - y = 11

4*x - 5*y = 10

We want to add them in a given form that one of the variables cancels, so we can solve it for the other variable.

Then we can take the first equation:

-x  - y = 11

and multiply both sides by 4.

4*(-x - y = 11)

Then we get:

4*(-x - y) = 4*11

-4*x - 4*y = 44

Now we have the two equations:

-4*x - 4*y = 44

4*x - 5*y = 10

(here we can think that we multiplied the second equation by 1, then we have k = 4, and j = 1)

If we add them, we get:

(-4*x - 4*y) + (4*x - 5*y) = 10 + 44

-4*x - 4*y + 4*x - 5*y = 54

-9*y = 54

So we combined the equations and now ended with an equation that is really easy to solve for y.

y = 54/-9 = -6

Now that we know the value of y, we can simply replace it in one of the two equations to get the value of x.

-x - y = 11

-x - (-6) = 11

-x + 6 = 11

-x = 11 -6 = 5

-x = 5

x = -5

Then:

x = -5, and y = -6

Answer:

10 apples

Step-by-step explanation:

We can write a ratio to solve

3 oranges     15 oranges

--------------- = -----------------

2 apples           x apples

Using cross products

3x = 2 * 15

3x = 30

Divide by 3 on each side

3x/3 = 30/3

x = 10

Answer:

He can expect to sell 10 apples

Answer: 55.4

Step-by-step explanation:

Remember soh cah toa

tangent = adjacent/opposite

angle is 18 degrees

Opposite is 18

Adjacent is x

So tangent of 18 degrees = 18/x

Use calculator to find tangent of 18 =0.3249

So 0.3249 = 18/x

Reciprocal both sides

3.0777 = x/18

Multiply both sides by 18

x = 55.3983

You may need to round

Answer:

-11/10 (fraction) or -1.1 (decimal)

Step-by-step explanation:

The slope formula is m=(y2-y1)/(x2-x1)

x1 = 7

x2 = -3

y1 = -7

y2 = 4

So, it’s: (4 - (-7))/(-3-7)

= (4+7)/(-3-7)

= (11)/(-10)

= -11/10 or -1.1

Answer:

D: 12

Step-by-step explanation:

1) So what I did at first was convert the fractions into decimals.

(Personally, this makes it easier, for me at least)

2) The problem states that for every 0.25 cups of broccoli, 0.60 grams of fiber are added as well to the mix. You can also convert this into a fraction. (It doesn't matter which one is the numerator/denominator, but for this example, I used the 0.25 cups of broccoli as the numerator.

3) Next step would be making another fraction. This time, the fraction is for the 5 cups of broccoli. Since we don't know the amount of grams for the fiber, we will replace it with an "x".

4) Realize, that |  [tex]\frac{0.25}{0.60} =\frac{5}{x}[/tex] |  To figure out the answer to this part, you can cross-multiply

5) Then at last, divide both sides by [tex]0.25[/tex] and you'll get:

Sorry this may have taken a long time; I just wanted to make sure everything was correct. Hope you do well on math, whether it's a test, or just homework. Good luck! :D
