Mrs. Zamir wants to buy 8 protractors and some erasers for her classroom.She has $30.00. If protractors cost $2.65 each, how muc
goblinko [34]

Mrs. Zamir has \fbox{\bf\$8.8} left to buy eraser.

Further explanation :

Multiplication is a mathematical operation such that two real numbers are performed in such a way that they derive a third number called product.

For example:

There are two numbers 4{\text{ and 5}} then multiply both the numbers as,

4\times5=20

Therefore, 20 is the product of 4 and 5.

It is given that Mrs. Zamir wants to buy 8 protractors and some erasers for her classroom.

She has total \$30.

If the price of the protractor is \$2.65 each.

Therefore, she spends total amount of money  on protractor can be calculated by multiplying 8 protractors by 2.65 as,

\begin{aligned}n&=8\times2.65\\&=21.2\\\end{aligned}

Thus, she spends \$21.2 on protractors.

Now, she has total \$30 and \$21.2 she spends on protractors.

Therefore, she left with the amount r as,

\begin{aligned}r&=30-21.2\\&=8.8\\\end{aligned}

Therefore, she has \fbox{\bf\$8.8} amount left for eraser.

At 3 p.m. an oil tanker traveling west in the ocean at 14 kilometers per hour passes the same spot as a luxury liner that arrive
schepotkina [342]
<span>N(t) = 16t ; Distance north of spot at time t for the liner. W(t) = 14(t-1); Distance west of spot at time t for the tanker. d(t) = sqrt(N(t)^2 + W(t)^2) ; Distance between both ships at time t. Let's create a function to express the distance north of the spot that the luxury liner is at time t. We will use the value t as representing "the number of hours since 2 p.m." Since the liner was there at exactly 2 p.m. and is traveling 16 kph, the function is N(t) = 16t Now let's create the same function for how far west the tanker is from the spot. Since the tanker was there at 3 p.m. (t = 1 by the definition above), the function is slightly more complicated, and is W(t) = 14(t-1) The distance between the 2 ships is easy. Just use the pythagorean theorem. So d(t) = sqrt(N(t)^2 + W(t)^2) If you want the function for d() to be expanded, just substitute the other functions, so d(t) = sqrt((16t)^2 + (14(t-1))^2) d(t) = sqrt(256t^2 + (14t-14)^2) d(t) = sqrt(256t^2 + (196t^2 - 392t + 196) ) d(t) = sqrt(452t^2 - 392t + 196)</span>
