The new total is 60%, but the sales tax is 5% of the bill. how much is the salestax?

Nataly_w [17]

Answer:

Sales tax is 8.33 % of new total

Step-by-step explanation:

Let

Your bill =1000

New total 60%=1000*60/100=600

5% sale tax on whole bill price =1000*5/100=50

To deduct 5% sale tax in 60% of new total the % are=50/600=0.0833*100=8.33%

So,

Sale tax is 8.33% of new total 60%.

Sometimes, but not always.
For example - If I vote for my candidate then he will win.
Reverse - If I don't vote for my candidate then he will not win.
The answer is false because an if then statement is a hypothesis not a fact.<span />

Calculate the slope of the line on the graph

Tamiku [17]

Answer:

3.5 (meters per second)

Step-by-step explanation:

To calculate the slope, we need two points. Let's see if we can select two points from the graph.

From the graph, we can pick out two possible points.

At the beginning, (0,2.5) is a valid candidate.

And at the end, with (5,20). Thus, let's use the slope formula to calculate the slope.

The slope formula is:

$m=\frac{y_2-y_1}{x_2-x_1}$

Let (0,2.5) be x₁ and y₁ and let (5,20) be x₂ and y₂. Thus:

$m=\frac{20-2.5}{5-0}$

Simplify:

$m=\frac{17.5}{5}\\ m=3.5$

Thus, the slope is 3.5 meters per second.

Further notes:

And the entire equation will be:

$m=3.5s+2.5$
