2. Using 50 for the number of weeks in a year is a(n) exponent

Paladinen [302]

There are 52 weeks in a year.

Using 50 for the number of weeks in a year is a(n) round.

Rounding is a process which we approximate the known number by just scaling it up or down.

In rounding the numbers less than 5 are scaled to one number less than the given integer and numbers such as 5 or above than 5 are scaled a number greater than the given number .

For example if there were 55 or more than weeks in a year we can say there are approximately 60 weeks in a year.

But there are 52 weeks so we round it to 50 weeks as 2 is less than 5.

A math textbook is 1 1/4 in. thick. how much shelf space is needed for 30 copies of the book?

inysia [295]

Hello!

You have to multiply 1 1/4 by 30 because each math book is 1 1/4 in. thick, and 30 books is 1 1/4 by 30. First change 30 and 1 1/4 to an improper fraction.

$\frac{30}{1} \times \frac{5}{4} = \frac{150}{4} = 37 \frac{1}{2}$

$\framebox{37 1/2 inches}$

Audrey reads 14 pages a day and Lauren reads 7 pages a day. If Audrey is on page 56,on what page is Lauren?

Papessa [141]

Answer:

Hey!

Your answer is that Lauren is on page 28!

Step-by-step explanation:

This is because is Audrey reads 14 pages and Lauren reads only 7 that means Audrey is reading twice as much as Lauren..

So if Audrey has read 56 pages, to find how much Lauren has read, divide 56 by 2 which gives you 28

so Lauren has read 28 pages...

Some math help please thaank ye

The 'template' for a quadratic function is:
$f(x) = ax^{2}+bx+c$ , where a is the vertical stretch/compression factor.
If the a in f(x) is 2/5, then vertically stretching the function is done by multiplying the function by 2, making:
$g(x) = 2(\frac{2}{5}x^{2}-2)\\g(x)=\frac{4}{5}x^{2}-2$
