Hello,

$2^{\frac{2}{3}}=\sqrt[3]{2^2} =\sqrt[3]{4}$

The correct answer is the first option. Two to the power of 2 over 3 is best defined by <span>Cube root of 4. It is best understood when written in numbers.

2^(2/3)

The denominator here represents the radical and the numerator is the power by which the base is raised. Therefore, it can be written as:

</span>∛2^2 or ∛4<span>

Your dinner bill comes to $19.68. Estimate your total cost for dinner with a 5% tax and a 20% tip on the original bill. Justify

barxatty [35]

Estimate:
Bill = $20 approximately.
5% tax on $20 = 20/20=$1
20 % on ($20) = $4
Total cost = $20+1+4 = $25
Total bill = $25 approximately.

Exact calculations
bill = 19.68
tax 5% = 0.98
Tip 20% of original = 3.94
Total bill = 19.68+0.98+3.94 = 24.60

What are the solutions to the equation |x – 10| – 4 = 2x?

Yuliya22 [10]

|x – 10| – 4 = 2x

x - 10 - 4 = 2x

x - 14 = 2x

x - 2x = 14

-x = 14

x = -14

Can you answer these 3 questions for me plz

finlep [7]

A.
$1hr \: 15min = 75min$

$c = 0.22t = 0.22 \times 75 = 16.5$

cost is $16.50

B.

$26.40 = 0.22 \times t$

rearrange to solve for t:

$t = \frac{26.40}{0.22} = 120min$

C. This is the same as part B, only the rate changed

$t = \frac{26.40}{0.25} = 105.6min$

they ask for the greatest number of minutes, so we round down (take the floor of the value).

the answer is 105 minutes.

Can someone explain this I dont understand it

IrinaVladis [17]

Y = mx + b

m is your slope AKA rate of change
b is the y intercept.

from the graph we can see that the y intercept (b) is 15. (look at the y axis and see what point the line crosses on the y, here it is 15, in-between 10 and 20)

slope is rate of change. to figure this out remember slope = rise over run:

$slope = \frac{rise}{run}$

so pick two points. how much does one point rise after the other point you picked? In the graph it rises 1 square so rise = 1

Now looking at the same two points, how far away from each other are they on the x axis? Looking at the graph they are 2 squares away from each other. so run = 2

Now plug these numbers into the rise over run formula:

$slope \: = \frac{1}{2}$

Now we have everything we need to put into our formula for a line:

$y = mx + b$
$y = \frac{1}{2} x + 18$

For number 16 you should get:

$y = \frac{1}{5} x + 3$

after you do the same steps again yourself
