Answer:

See explanation below.

Step-by-step explanation:

First, obtain the percentage of sales tax for a sale. Say it is 5%.

Then, obtain the sale prices, for two items say they are: $25.00 and $15.00.

Add the amounts together to obtain the subtotal:

$25.00 + $15.00 = $40.00, is the subtotal.

Multiply the amount by the percentage:

$40.00 * 5% =

40 * .05 = $2.00, is the sales tax

Add the tax to the subtotal to obtain the total amount to pay:

$40.00 + $2.00 = $42.00, is the total amount to pay.

Hope this helps!! Have an Awesome Day!! :-)

A number is 42,300 when multiplied by 10. find the product of this number and 500.
Makovka662 [10]
A number multiplied by 10 will just have a zero added onto the end of it.
For example: 4x10=40
5x10=50
10x10=100

So, in this case 4,230 would be multiplied by 10 to get 42,300.

4,230x500= 2,115,000

PLEASE HELP WILL MARK BRAINLIEST AND GIVE 50 POINTS
Alexeev081 [22]

Answer:

The correct option is;

e. 2500

Step-by-step explanation:

The formula for sample size is given by the following formula;

n = \dfrac{z^2 \times \hat p(1 - \hat p)}{\epsilon ^2}

At 95%, z = 1.96

ε = Margin of error = 0.02 = 2%

Finding the sample size, n, given only the margin of error is by the following formula;

Margin of error = 100/√n

Therefore, we have;

2 = 100/√n

√n = 100/2 = 50

n = 50² = 2500

Therefore, the correct option is e. 2500.

How can i identify a slope
Nonamiya [84]

Answer:

Rise over Run.

Step-by-step explanation:

If it's on a line on a graph you count how many it goes up until it's aligned with the next point and then you count how ever many over until it hits it. So it could be 2 up and 4 over making the slope 2/4.

I'm sorry that might not make much sense I'm bad at explaining but let me know if that helps at all!!
