Answer:

27%

Step-by-step explanation:

The total books sold were 182 and the amount of books sold that were nonfiction hardcover were 49 as represented in the frequency table.

To find the percentage we must divide the nonfiction hardcover by the total books.

49/182≈0.269 or 0.27

Multiply the decimal by a 100 to change it into a percentage, so our answer is 27%.

Answer:

288

Step-by-step explanation:

To solve, we need to find the area of the four triangle sides and add that to the square base's area.

Area of triangle sides: base * height * 0.5

Area of square base: base * height

Substitute the values

8 * 14 * 0.5 = 56

There are four of these sides, so the area of all the triangles is 224.

The square base is 8 * 8, or 64

Add these two values together.

64 + 224 = 288

Thus, the answer is 288

A worker on the production line is paid a base salary of $230.00 per week plus $0.78 for each unit produced. Write an equation

iogann1982 [59]

(a)

We are given

A worker on the production line is paid a base salary of $230.00 per week

so, base salary =230

Let's assume number pencils produced as x

plus $0.78 for each unit produced

now, we can find equation for earnings

$E(x)=230+0.78x$

now, we are given

her earnings of $446.84 for a week when she produced x units

so, we can set E(x)=446.84

and then we can solve for x

$446.84=230+0.78x$

$230\cdot \:100+0.78x\cdot \:100=446.84\cdot \:100$

$23000+78x=44684$

$23000+78x-23000=44684-23000$

$78x=21684$

$\frac{78x}{78}=\frac{21684}{78}$

$x=278$

so, number of pencils = 278........Answer

(b)

If the worker had produced twice that number of units

so, number of pencils =2*278=556

now, we can find earnings

$E(x)=230+0.78x$

now, we can plug x=556

$E(556)=230+0.78*556$

$E(556)=663.68$ .................Answer

So we know that the slope intercept form is y=mx+b

so the formula is y=3*-3+-6
