The correct numbers to use in solving problems about spans of time like B.C. and A.D. should be “integers”.

Integers are whole numbers (not a fractional number or not a decimal number) which can take a value of negative, zero, or positive number. Example of integers would be -1, 0 and 1.

<span>In calculations, the time period would be on the x-axis. Since B.C. and A.D. are two different spans of time, therefore in the calculations, the date of BC should be negative (negative x-axis) while the date of AD should be positive (positive x-axis). This would place the origin as the common reference.</span>

Chase goes out to lunch. The bill, before tax and tip, was $11.90. A sales tax of 9% was added on. Chase tipped 17% on the amoun
WINSTONCH [101]

Answer:

$15.17

Step-by-step explanation:

First we calculate the value for the sales tax:

11.90 \times  \frac{9}{100 }  = 1.07

we then add the value for the sales tax ($1.07) to the initial bill:

11.90 + 1.07 = 12.97

We were instructed to calculate the tip after the sales tax was added so:

12.97 \times  \frac{17}{100}  = 2.20

after we will add the value for the tip to the value that we have for the bill ( this is the new value that includes the sales tax) to find the total cost:

12.97+ 2.20  = 15.17

<em>Therefore</em><em> </em><em>the</em><em> </em><em>total</em><em> </em><em>cost</em><em> </em><em>for</em><em> </em><em>his</em><em> </em><em>mean</em><em> </em><em>is</em><em> </em><em>$</em><em>15.17</em>

Multiply the fractions:<br> 2 / 5 ∙ 3 / 4.
Bingel [31]

Answer:

\frac{3}{10}

Step-by-step explanation:

\frac{2}{5} * \frac{3}{4} can be solved by just multiplying the numerators together and the denominators together

2 * 3 = 6 and 5 * 4 = 20 so the answer would be \frac{6}{20}

This simplifies to \frac{3}{10}
