In this question it is given that

Carla earns $8.43 per hour. It means that her hourly rate is $8.43 .

And we have to find her overtime pay at time-and-a-half.

First we have to understand what time and a half means .

Time and a half means 1.5 times of the normal rate. And to find the overtime pay, we have to multiply 1.5 and normal hourly rate. That is

=1.5*8.43 = $12.65

Therefore correct option is a .

How do you solve 10≤2x≤x+9? The answer says it's 5≤x≤9 but i have no idea how it got there
Tanya [424]

Answer:

Step-by-step explanation:

so why this kind of problem is so confusing is b/c it's 2 problems in one

if you were to expand this it look like this

10 ≤2x

and

2x ≤x+9

This is really saying.. that x has a range.. and that the 1st equations is the lower stop point,  and that the 2nd equations is the upper stop point

once it's taken apart.. I bet you can solve it pretty quickly.

5≤x

and

x ≤9

then just put it back together in that confusing .. yet handy way to write it,

5≤x≤9

Marne Shia walked 3/8 of a mile in 3/5 of an hour. What equation can be used to calculate her unit rate in miles per hour?
Dafna11 [192]

Answer:

speed = (3/8 mi)/(3/5 h)

Step-by-step explanation:

... speed = distance/time

Fill in the given values:

... speed = (3/8 mi)/(3/5 h)

_____

<em>Comment on units</em>

You can use the units to provide both guidance and assurance. You know speed is generally expressed in <em>miles per hour</em>. If you consider "per" to mean "divided by", this expression of units tells you speed is calculated by dividing miles by hours.

If you leave the units with the numbers, as we have above, they enter into the calculation the same way any variable might. You can do the arithemetic with the numbers, and you can indicate the arithmetic with the units (just as you would with any variables). Here, the result of evaluating the equation would be ...

\displaystyle\frac{\frac{3}{8}\,\text{mi}}{\frac{3}{5}\,\text{h}}=\frac{\frac{3}{8}}{\frac{3}{5}}\,\frac{\text{mi}}{\text{h}}=\frac{5}{8}\,\text{mi/h}

The fact that the units come out mi/h (the units of speed) provides assurance that you probably did the math correctly.

Find the missing values for the exponential function represented by the table below.
mylen [45]
<h3>Answer:</h3>

c. 27 40.5

<h3>Step-by-step explanation:</h3>

Step 1 is "read and understand the problem." Step 2 is "read the answer choices."

To choose the correct answer here, you only need to know that exponential growth functions are non-decreasing. The next y-values cannot be smaller than the values already shown.

_____

If you insist on doing some calculation, ...

Comparing adjacent values, you see that the common ratio is 3/2.

  • 18 × 3/2 = 27
  • 27 × 3/2 = 40.5

A bacterium triples in size every 6 minutes. If you start with 3 bacterium
docker41 [41]

9514 1404 393

Answer:

  E  none of the above

Step-by-step explanation:

"Triples in size" means the growth factor is 3, so we expect to see that as the base of the exponent. That growth factor applies to a period of 6 minutes, or 1/10 hours. The number of 6-minute intervals in t hours is 10t, so we expect to see that as the exponent. The appropriate model could be written ...

  n(t) = 3·3^(10t) . . . . . matches no offered answer choice
