A plant costs £6.80.Julie has £30.00 how many plants can she buy?

irinina [24]

Answer:

Julie can buy 4 plants

Step-by-step explanation:

A plant costs £6.80 and Julie has £30.

In order to find out how many plants she can buy with £30, we need to see how much times £6.80 can go into £30. In other words, we need to divide £30 by £6.80 so we get the number times it can go into £30. That will be the number of plants.

£30 ÷ £6.80 = 4.41176470588

Julie can't get 0.41176470588 of a plant so we have to round it to 4. She can buy 4 plants.

She has a bit of money left over (you can tell by the decimal number), but that isn't enough to buy another plant. So she buys 4 and has £2.80 left.

£6.80 x 4 = £27.20

Please help me find out what the question marks are

quester [9]

Question a

g(x) times $\sqrt{x-5}=\sqrt{x^2-5}$
divide both sides by √(x-5)
$g(x)=\frac{\sqrt{x^2-5}}{\sqrt{x-5}}$
$g(x)=\frac{(\sqrt{x-5})(\sqrt{x^2-5})}{x-5}$
$g(x)=\frac{\sqrt{x^3-5x^2-5x+25}}{x-5}$

question b
$g(x) \space\ times \space\ 1+\frac{1}{x}=x$
divide both sides by 1+1/x
$g(x)=\frac{x}{1+\frac{1}{x}}$
times by x/x
$g(x)=\frac{x^2}{x+1}$

question c
$\frac{1}{x} \space\ times \space\ f(x)=x$
times both sides by x
$f(x)=x^2$

question d
the (f*g)(x) collumn seems to have a domain of only x is greater than or equal to 0?
so maybe we squared the whole thing, ya
wait
ah, ya
basically
$|x|=(\sqrt{x})^2=(\sqrt{x})(\sqrt{x})$
so f(x)=√x

a. $g(x)=\frac{\sqrt{x^3-5x^2-5x+25}}{x-5}$
b. $g(x)=\frac{x^2}{x+1}$
c. $f(x)=x^2$
d. $f(x)=\sqrt{x}$
