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:

Answer:-5,5,5

Step-by-step explanation:

Answer:

$5

Step-by-step explanation:

First, we need to find the total amount he spent on the passes.

We just need to multiply the number of passes by the price of each pass.

19 x 1.4 = 26.6

This means he spent $26.6 on the passes.

Now, we can find out how much he spent on the discount card.

Just subtract his total spending amount by the amount he spent on passes.

31.6 - 26.6 = 5

He spent $5 on the discount card.

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

(36 x 12) + (60 x 5) = 732

Answer:

5/9

Step-by-step explanation:

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

Answer:

-1.6

Step-by-step explanation:

Since they're both negative and you're adding, you would do the same if you added normally, but you would add a negative sign.

Answer:

-2.6

Step-by-step explanation:

-1.4 + (-1.2)

-1.4 - 1.2

-(1.4+1.2)

-2.6

Remember that adding a negative is the same as subtracting a positive.

Answer:

408 is correct

0.8 x 510 = 408

Step-by-step explanation:

When we get a sale value or reduced value to find

This is a short cut of workings in bold to find correct value.

10% of 510 = 51

20% of 510 = 102

510-102 =408

17 x 30 = 510   Not correct as calculated before taxes.

100-80/ 100 = 0.8

0.8 x 510 = 408

408/510 = 0.8  Is correct

0(17) (30) = 510   Not correct as calculated before tax

510 - 2(17)(30) = 510 i Not correct as calculated before tax.

Step-by-step explanation:

Cross multiply 3/4 and 1/3 which gives you 9/12 and 4/12

Add them together 9/12 + 4/12 = 13/12

Reduce 13/12

Step-by-step explanation:

  Equation of a linear function is defined by equation y = mx + b,

where m = slope of the line and b = y-intercept

  Linear model representing a function for the earning (y) to photograph the houses (x) will be,

y = 140x + 35

   Let the linear equation representing the earnings to photograph the houses,

y = mx + b

         If we graph a line with two variables, earnings from photography on y-axis and the number of houses at x-axis,

Slope of the line 'm' = [tex]\frac{\triangle y}{\triangle x}[/tex]

     If two points lying on the line are (2, 315) and (7, 1015).

Slope of the line 'm' = [tex]\frac{1015-315}{7-2}[/tex]

                                 = [tex]\frac{700}{5}[/tex]

                                 = 140

     Therefore, equation of the line will be,

y = 140x + b

       Since, (2, 315) lies on the line,

315 = 140(2) + b

315 = 280 + b

b = 35

       Now the equation will be,

y = 140x + 35

        Therefore, linear model representing a function of the earning (y) to photograph the houses (x) will be,

y = 140x + 35

Step-by-step explanation:

First we combine your first set of terms,

7b^2 + 2b^2 = 9b^2

There's a subtraction hidden in there!

9b^2 - 3b^2 = 6b^2

Next we do the same thing for the second term,

3b + 7b = 10b

but there's a subtraction in the expression!

10b - b = 9b

Then we finish with our third term

6 + 5 = 11

Answer:

6b^2 + 9b + 11

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

10and-4

Frequency polygons are used to show the trend between the elements of a given dataset and the frequency of each element.

From the dataset, we have the following class of 6 and the frequency:

[tex]Class \to Frequency[/tex]

[tex]0 - 2 \to 9[/tex]

[tex]3 - 5 \to 18[/tex]

[tex]6 - 8 \to 7[/tex]

[tex]9 - 11\to 0[/tex]

[tex]12 - 14 \to 5[/tex]

[tex]15 - 17 \to 4[/tex]

So, the frequency distribution is as follows:

[tex]\begin{array}{ccc}{Class}&{Frequency}&{x}\\0-2&9&1\\3-5&18&4\\6-8&7&7\\9-11&0&10\\12-14&5&13\\15-17&4&16\end{array}\right][/tex]

The class midpoint (x) is calculated by calculating the mean of each class.

For instance, the midpoint (x) of class 0 - 2 is:

[tex]x = \frac{1}{2}(0+2) = \frac{1}{2} \times 2 =1[/tex] ---- and so on

The class midpoint (on the x-axis) is plotted against the frequency (on the y-axis) to create the frequency polygon (see attachment)

Draw 4 by 2 boxes in 1cm, and measure it diagonally it will measure 4.5 if each square has the same length

f(x)=2

f(x) is the function, x inside represent the input, while the value the function is equal to is the output.

So to solve for x, look at where f(x)/ y is equal to 2. And, from there the function is equal to 2 when x=-1.

So your answer is x=-1
