It is a very simple question to answer.

Obviously first we can calculate the number of hours that he over timed. So 5 hours he worked over time. So an equation to set this up equals to 30*x + 5*1.4x = 436.60.

On re arranging the equation and making x the subject, The answer comes out to be 37 x = 436.6. x = 11.8. So he earns around 11.80 $ per hour.

(3.2 * 10000000) -3
andreev551 [17]

The exponents distribute over factors:

(ab)^c = a^c \times b^c

so, you have

(3.2 \times 10^6)^{-3} = 3.2^{-3} \times (10^6)^{-3}

Let's focus on each factor: applying the definition of negative exponents, you have

3.2^{-3} = \cfrac{1}{3.2^3} \approx 0.03

While for the power of 10, you can use the following rule

(a^b)^c = a^{bc} to write

(10^6)^{-3} = 10^{6\cdot (-3)} = 10^{-18}

So, the expression evaluates to

0.03\times 10^{-18} = 3\times 10^{-20}

PLEASEEE HELP ME WITH THISSS
zaharov [31]

Answer:

x=14

Step-by-step explanation:

This is asking for the ratio of A to B.

The x-10 is 1.

The 28 is 7.

Find the scale factor by executing 28/7=4.

So, you would want polygon A to be 4 in order to be proportional to polygon B.

Now, you can just guess and check that 14-10=4

Or, you can set up the equation as follows: x-10    =    4

                                                                         +10        +10

                                                                           x      =   14 is your answer.

What is the slope of the line shown below (3 9)(-4 2)
Semenov [28]

Answer:

slope = 1

Step-by-step explanation:

calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (3, 9 ) and (x₂, y₂ ) = (- 4, 2 )

m = \frac{2-9}{-4-3} = \frac{-7}{-7} = 1

What is the area ? 3.14 = pi
Lapatulllka [165]

Answer:

236.25  cm^{2}

Step-by-step explanation:

To get the area of the shaded portion, add up all the areas of the 3 quadrants

First, find the area of one quadrant

Area of a quadrant = 1/4 πr^{2}

π = 3.14

Radius, r = 10 cm

A = 1/4 *3.14 * 10^{2}

A = 1/4 *3.14 * 100

A = 1/4 *314 cm^{2}

A = 78.75 cm^{2}

Now, multiply by 3

3 * 78.75

= 236.25  cm^{2}
