inysia [295]

Answer:

Yes ,is a reasonable amount. If she has $20 she will have enough to buy the shirt

Step-by-step explanation:

we know that

The total amount is equal to the price of the shirt plus the sales tax

we have that

$100\%+4.8\%=104.8\%=104.8/100=1.048$

Multiply 1.048 by the cost of the shirt

$\$18.95(1.048)=\$19.86$

Compare

$\$19.86 < \$20$

therefore

Yes ,is a reasonable amount. If she has $20 she will have enough to buy the shirt

Is (-a + b)² = a² - 2ab + b² right or wrong, and why?

antiseptic1488 [7]

Answer:

$\huge\boxed{\sf Right.}$

Step-by-step explanation:

$(-a+b)^2$

Let's apply the formula (x+y)² = x² + 2xy + y²

Here, x = -a and y = b

So,

= (-a)² + 2(-a)(b) + (b)²

= a² - 2ab + b²

Hence, it has been proved that (-a + b)² = a² - 2ab + b².

Does it help to remember and/or list out your square roots

ololo11 [35]

It is a good thing to remember. Of course, not all, but some basic numbers that appear all the time such as the numbers from 2 to 13 should be remembered as they appear in numerous assignments and tests.
