Maria spent $28.69 on one pair of jeans and two T-shirts.The jeans cost $16.49. each T-shirt cost the same amount.The sales tax is $1.62.How much did each T-shirt cost?

Answers

Answer 1
Answer: First we have to subtract 28.69-1.62 to get the cost without taxes.
28.69-1.62=27.07$
Now we have to subtract 27.07 -16.49 to get the cash spent on the t-shirts.
27.07-16.49=10.58$
Finally we have to subtract 10.58:2 to get the answer how much each t-shirt cost.
10:58:2=5.29$ - its the answer
Answer 2
Answer: 28.69-16.49=12.20
12.20-1.62=10.58
10.58/2=5.29
each t-shirt costs 5.29

Explain

Answers

With grid paper, each square is the same area. If the grid paper used is one-inch grid paper, that means each square on the paper is one square inch.Therefore, if Maria wants to draw something that is 40 square inches, it will fill 40 squares on the one-inch grid paper.

If log3 8 ≈1.8928, evaluate log3 72

Answers

Final answer:

To evaluate log3 72, given that log3 8 is approximately 1.8928, we use properties of logarithms. We can express 72 as 8×9, and since log3 9 equals 2, log3 72 is 1.8928 + 2, which is 3.8928.

Explanation:

The student is asking to evaluate log3 72 given that log3 8 ≈1.8928. We can use the properties of logarithms to solve this. Since 72 can be expressed as 8×9, and we know that log3 8, we can find the log3 9 by understanding that 9 is 3²and therefore log3 9 is 2, because the base and the argument are the same.

Now, using the property of logarithms that loga (xy) = loga x + loga y, we can write log3 72 as:

log3 (8 ∙9) = log3 8 + log3 9

log3 72 = 1.8928 + 2

log3 72 = 3.8928
