A machine prints 8 banners in 120 seconds how many seconds does it take to print one Banner

2 answers:

8 0

So all we have to do is divide 120 by 8 so 120/8= 15

Do you understand why we do that? It’s because there are 120 seconds needed to print 8 banners so dividing 120 by 8 will get you the time for one

Katie gives Maggie half of her pencils. Maggie keeps 5 and gives the rest to jamil. Write an expression for the number of pencil

Inga [223]

Answer

Write an expression for the number of pencils Maggie gives to jamil.

To prove

Let us assume that the number of pencils Katie have = x

As given

Katie gives Maggie half of her pencils.

$Katie\ gives\ Maggie\ half\ of\ her\ pencils = \frac{1x}{2}$

As given

Maggie keeps 5 and gives the rest to jamil.

Thus

$Number\ of\ pencils\ Maggie\ gives\ to\ jamil = \frac{1x}{2} - 5$

Therefore the expression for the number of pencils Maggie gives to jamil are $\frac{1x}{2} - 5$ .

The required value is $2\times10^9$

Step-by-step explanation:

Weight of ants = $4\times10^{-3}$

Weight of elephant= $8\times10^6$

We need to find, the total weight of about how many ants equals to the weight of an oversized elephant.

The equation given is:

$4\times10^{-3} \times a = 8\times10^6$

We need to find a:

Solving:

$4\times10^{-3} \times a = 8\times10^6\\a=\frac{8\times10^6}{4\times10^{-3}}\\if \,\,10^a/10^-b \,\,then\,\, 10^{a+b}\\a=2\times10^{6+3} \\a=2\times10^9$

So, the required value is $2\times10^9$
