Your printer takes 36 seconds to print a small photo and 60 seconds to print a large one.
a.) Write an expression for the time (in seconds) your printer would take to print a batch
including both small and large photos.
b.) Find the time your printer would take to print 12 small photos and 5 large photos.

Answers

Answer: for part B = 732 seconds or 12.2 minutes

Step-by-step explanation: 36 seconds times the amount of small photos 12 = 432 plus 60 seconds times the amount of large 5 photos = 300 , 432 plus 300 equals 732 seconds

Job A: $8.95 per hour (40 hours a week)​​Job B: $16,400 per year
​a. Which job pays more?
​b. How much more?

Answers

Job A pays more

Job A pays about $19332, as job B pays 16,400 per year.

Answer:

A) Job A pays more.

B) $784 dollars more than job B.

Step-by-step explanation:

We know that job B Makes $16,400 per year. We just need to find out how much job A makes in a year.

Job A: 8.95 x 40= $358 in a week.

We know that there is 4 weeks in a month and 12 months in a year.

12 x 4 = 48.

48 weeks in a year x $358 in a week= $17,184

We now know that job A pays more than iob B.

In order to find out how much more we will use the formula Job A- Job B= Difference between.

$17,184-$16,400= $784

Job A pays $784 dollars more than job B.

Answer:

1) $2.6

2) $9.9

Step-by-step explanation:

for the first one, you first add $1 with 1$ and you would get 2 and then you do 55 cents plus 5 cents which would get 60 cents and then you get $2.60.

For the second one, you multiply 2.60 by 3 and you get $7.80 and you still have $2.10 left so you add that to $7.80 then you get $9.9

Ken went to a county fair and spent $5 on admission, $6.50 on games, and $7.21 on food. If he had $30 before he went to the fair, how much money does he have left?

Answers

5+6.50+7.21=18.71 30-18.71=$11.29 left

Answer:

Below

Step-by-step explanation:

To find Ken's leftover amount of money, all you need to do is subtract what he spent from his initial amount :

     $30 - $5 - $6.50 - $7.21 = $11.29

So, Ken has $11.29 left after he goes to the fair

Hi there!

(z)

We know that the two segments with "z" are congruent, so:

z + 15 = 5z + 9

Solve for z:

15 = 4z + 9

6 = 4z

z = 3/2

(y)

We know that (7y + 6) = 90° (indicated by the square angle), so:

7y + 6 = 90

7y = 84

y = 12°

(x)

Segments (x + 26) and (3x - 8) are congruent, so:

x + 26 = 3x - 8

26 = 2x - 8

34 = 2x

x = 17

537.95 x 9.5% = ?

Step 2

Convert the % to a decimal:

9.5% to 0.095

Step 3

Rewrite the problem with decimal replacing the percentage.

Now the problem looks like this:

537.95 x 0.095 = 51.11

This problem gives the amount of the tax.

Step 4

Add the original price with the tax amount:

537.95 + 51.11 = $589.06 (total cost)

Answers

Answer:

6 to the left 4 down (-6,-4)

name a point that is 20 units away from (5,-2)​

Answers

Answer:

Distance between both points is 20units.

Applying the Distance between Points Formula

d= √(y₂-y₁)²+(x₂-x₁)²

x₁= 5 y₁=–2

x₂= ? y₂= ?

20 = √ [y -(-2)]² + (x - 5)²

Taking the square of both sides to eliminate the square root on the right.

20² = ( y + 2)² + (x - 5)²

400 = y² + 4y + 4 + x² – 10x + 25.

400 = x² + y² – 10x + 4y + 29.

x² + y² – 10x + 4y = 400 – 29

x² + y² – 10x + 4y = 371--------------eqn 1.

We called that eqn 1 cause we need another equation to solve this.

To solve an Equation with 2 variables... You need 2 equation.

To solve that of 3 variables.... you need 3 equations(Basic Math Rules).

We're dealing with 2 variables in this case(x, y).

Now

We'd need to think in order to create another equation that'll satisfy the distance or point.

We know that the distance between both Points(known and unknown) is 20.

Half that distance is 10.

The distance of 10 will occur at the center of these 2 points.

So lets apply the formula for Mid point to get the coordinate of the center.

Midpoint

let p be the x position and q be the y position of the midpoint

p = (x₁ + x₂)/2. q = (y₁ + y₂)/2

Starting from the know point (5 , -2)

x₁=5 y₁=–2

p = (5 + x)/2. q = (–2 + y)/2

p = (x + 5)/2 q = (y–2)/2.

This is the coordinate of the Midpoint.

Now We know that the distance between (5, -2) and [(x + 5)/2 , (y–2)/2] is 10(midpoint).

Applying the distance between points again.

d = √(y₂ - y₁)² + (x₂ - x₁)²

x₁= 5 y₁= -2

x₂= (x + 5)/2 y₂= (y–2)/2

10 = √[(y–2)/2 -(-2)]² + [ (x+5)/2 – 5)]²

10 = √[(y–2)/2 + 2]² + [(x+5)/2 – 5)]²

Squaring both sides to remove square root on the right and also Taking the LCM in each bracket

We have

10² = [ (y + 2)/2]² + [ (x–5)/2]²

Distributing the "2" on the denominator to each individual number in the parentheses.

100 = (y/2 + 1)² + (x/2 – 5/2)²

100 = y²/4 + y + 1 + x²/4 –5x/2 + 25/4.

Multiply through by 4 to clear fractions.

400 = y² + 4y + 4 + x² – 10x + 25

Rearranging

x² + y² – 10x + 4y = 371.

Hmm...

Equation 1 and 2 Are the Same.

Something is Wrong!

Pls Recheck the Question

I do believe that One value of the unknown point should be given.

I maybe be wrong somewhere else too.

Pls correct in the comment section if you spot it.

the points that are 20 units away from (5,-2)​ will be (25, -2), (-20, -2), (5, 18), (5, -22), and so on.

What are coordinates?

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

Given the coordinates of the point (5,-2)​.

Technically 20 units away from the given coordinates will make a circle with a radius of 20 units and the center with (5, -2).

Any point that lies on the perimeter of the circle will be our point

for easy understanding add or subtract 20 from either x or y coordinates of the points.

We will get our desired coordinates for instance:

(25, -2), (-20, -2), (5, 18), (5, -22), and so on,
