What is 645 divided by 50?

Answer:

slope=.5

intercept= 1

Answer:

24) D

25) D

Step-by-step explanation:

24) D

We want to find the equation of a line (in slope-intercept form) that passes through (2, -2) and is perpendicular to [tex]y=\frac{2}{5}x+2[/tex].

First, let's find the slope of our new line.

Remember that perpendicular slopes are negative reciprocals of each other.

Therefore, to find the slope of our new line, we will flip our old slope and add a negative.

Therefore, the slope of our new line is -5/2.

Now, we can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

So, let's substitute -5/2 for our slope and (2, -2) for our point (x₁, y₁). This yields:

[tex]y-(-2)=-\frac{5}{2}(x-2)[/tex]

Simplify:

[tex]y+2=-\frac{5}{2}(x-2)[/tex]

Let's convert this to slope-intercept form. Distribute the right:

[tex]y+2=-\frac{5}{2}x+5[/tex]

Subtract 2 from both sides. So, our equation is:

[tex]y=-\frac{5}{2}x+3[/tex]

Our answer is D.

25)

We know that the cost for buying x items is given by the function:

[tex]C(x)=6x[/tex]

We also know that the items are sold in packages of 10 only. And no one can buy more than 5 packages. In other words, we can buy 0, 1, 2, 3, 4, or 5 packages.

So, let's see how much it will be if we buy 0 packages. This will just be:

[tex]C(0)=6(0)=\$0[/tex]

If we buy 1 package, there will be 10 items in them. So:

[tex]C(10)=6(10)=\$60[/tex]

If we do this for 2 packages (20 items), 3 packages (30 items), and so on, we will get:

[tex]C(20)=6(20)=\$120\\C(30)=6(30)=\$180\\C(40)=6(40)=\$240\\C(50)=6(50)=\$300[/tex]

So, our range is:

[tex]\{0, 60, 120, 180, 240, 300\}[/tex]

The correct answer is D.

And we're done!

Step 1. Multiply

Step 2. Subtract

Step 3. Add

Step 4. Divide

Answer:

1. The system of equations is given as follows;

S + L = $1,300................(1)

S + 2·C = $1,400............(2)

S + L + C = $1,600.........(3)

Where;

S = The cost of a sofa

L = The cost of a love sea

C = The cost of a single chair

2. The cost of a love sea, L is $500

Step-by-step explanation:

1. The given information are;

The price of sofa and love sea = $1,300

The price of sofa and two chairs = $1,400

The price of sofa, love sea, and one chair = $1,600

Let the cost of a sofa = S

Let the cost of a love sea = L

Let the cost of a chair = C

Therefore, we have;

S + L = $1,300................(1)

S + 2·C = $1,400............(2)

S + L + C = $1,600.........(3)

2. From equation (1), we have;

L = $1,300 - S

Similarly, from equation (2),we have;

C = ($1,400 - S)/2

Substituting the values of L and C in equation (3), we have;

S + $1,300 - S + ($1,400 - S)/2 = $1,600

Which gives;

($1,400 - S)/2 = $1,600 - $1,300 = $300

$1,400 - S = 2 × $300 = $600

$1,400  = $600 + S

$600 + S = $1,400

S = $1,400 - $600 = $800

S = $800

The cost of a love seat, L, is given from the relation L = $1,300 - S, above, which gives;

L = $1,300 - $800 = $500

The cost of a love sea, L is $500 .

[tex]4x + 3 = 3x + 12[/tex]

Both sides minus 3

[tex]4x = 3x + 12 - 3[/tex]

[tex]4x = 3x + 9[/tex]

Both sides minus 3x

[tex]4x - 3x = 9[/tex]

[tex]x = 9[/tex]

So :

TVU = 3(9)+12 ----¢ TVU = 27 + 12

TVU = 39°

Answer:

a line passing through the points (2, -6) and (4, -16)

Step-by-step explanation:

y=-5x+4

you plug in the x value and put the y value on the left side of the equation

for example

-6 = -5(2) + 4

then solve to see if it works

-5(2) = -10 + 4 = -6

(2, -6) works

-16 = -5(4) +4

-5(4) = -20

-20 + 4 = -16

(4, -16) works

Answer:

1.) 12 hours   2.) She made a multiplying error in the table.

Step-by-step explanation:

1.)

First, let's find the slope of this equation:

m = 135 - 81 / 5 - 3

m = 54/2

m = 27

Therefore, the equation should be y = 27x.

Now we substitute 324 for y and solve for x:

324 = 27x

12 = x (Divided 27 on both sides.)

Therefore, someone would have to work 12 hours in order to earn $324.

2.)

For this problem, it appears Amanda has found the correct equation for her recipe. When taking a look at the table, however, it seems as though she has made a multiplying error.

Answer:

the answer willl be 50%  

The 60 percent of 50 equals 30.

To find what number is 60 percent of 30, you can set up the following equation:

0.60 * x = 30

Here, 'x' represents the unknown number that is 60 percent of 30. To solve for 'x,' divide both sides of the equation by 0.60:

x = 30 / 0.60

Now, perform the division:

x = 50

Therefore, 60 percent of 30 is 50. In other words, 50 is the number you are looking for, which is 60 percent of 30. You can verify this by calculating 60 percent of 50:

0.60 * 50 = 30

As expected, 60 percent of 50 equals 30.

Answer:

The fraction of the entire mail each person address = 1/8

Step-by-step explanation:

Given that:

number of people addressing envelopes = 6

If they gave out 3/4 of an entire mailing address.

Then, the amount of mailing not addressed is:

= 1 - 3/4

= [tex]\dfrac{4-3}{4}[/tex]

= 1/4

If 6 people shared 3/4 of an entire mailing to address evenly.

Then: each person gets:

[tex]=\dfrac{3}{4} \div 6[/tex]

[tex]=\dfrac{3}{4} \times \dfrac{1}{ 6}[/tex]

= 1/8

The fraction of the entire mail each person address = 1/8

Answer: 36

12 out of 15 people play in the school band. In the class, 36 do not play.

12:15 is equal to a ration of 36:45.

So, it is the answer. 36 out of 45 people in the class play in the band.

Hope this helps!

Answer:

9 I think

Step-by-step explanation:

I wanted to simplify 12 out of 15 and I did by dividing 3 out of both of them which would now equal 4 out of 5. I know that 4 out of 5 is 80%. so, I did 80 % of 45 which equals 36 which means 36 people were in band. So now you minus 36 from 45 which is 9

9 people did not play in band

Determine the coordinate of Round 4

Since, Mia score is round 2 and 3 combined;

We have:

Round 4 = 6 + 3

Round 4 = 9

Hence:

The coordinates is (x,y)
