Answer:

The fraction of the money that Lisa received will be 5x/13

Step-by-step explanation:

The the amount shared by Lisa and ant be x

If Lisa and ant share the money in the ratio 5:8, to get the fraction Lisa received;

Step1:

The total ratio will give:

5+8 = 13

Since the ratio Lisa got was 5, then the fraction of money Lisa receive will be:

Lisa ratio/Total ratio × Amount shared

= 5/13 × x

= 5x/13

Therefore, the fraction of the money that Lisa received will be 5x/13

<em>7 grams of sugar</em>

<h2>Explanation:</h2>

________________________________________

I'll assume your answer is as follows:

<em>A bowl of cereal had 3 3/6 grams of sugar in it. If Victor ate 2 bowl a week, how many grams of sugar would he have eaten?</em>

________________________________________

If so, then we know that:

A bowl of cereal had 3 3/6 grams of sugar in it.

Victor ate 2 bowl a week

In other words, the total of sugar he ate can be calculated as:

$3\frac{3}{6}\times2 \\ \\ Converting \ mixed \ fraction \ into \ improper \ fraction: \\ \\ =(3+\frac{3}{6})\times2 \\ \\ =(\frac{3(6)+3}{6})\times 2 \\ \\ =(\frac{21}{6})\times 2 \\ \\ =(\frac{7}{2})\times 2 \\ \\ =7$

So <em>he'd have eaten 7 grams of sugar</em>

Answer:

cos210=cos(180+30)=−cos30=−√32 . sin210=sin(180+30)=−sin30=−12 . 3(cos210+isin210) =3(−√32)+3i(−12). −(32)√3−(32)i. My favourite way of seeing that sin30=12 and cos30=√32 is ...

Find the distance between the points (2.7, 5.1) and (3, 4.7).<br> 0.05<br> 0.5<br> 5

tankabanditka [31]

Correct answer is B.

$(2.7,5.1)\Rightarrow x_1=2.7,y_1=5.1
\\(3,4.7)\Rightarrow x_2=3,y_2=4.7
\\
\\d= \sqrt{(3-2.7)^2+(4.7-5.1)^2}= \sqrt{0.3^2+(-0.4)^2} = \sqrt{0.09+0.16}
\\
\\d= \sqrt{0.25}=0.5$

Lunna [17]

Let pages written by Tom for a school report = x

Pages written by Jen for school report= 10 x

Pages written by Tom + Pages written by Jen = 396

→ x + 10 x = 396

→ 11 x =396

Dividing both sides by 11, we get

→ x =36,

Pages wrote by Tom= 36 pages

Pages wrote by Jen = 36 × 10=360 pages
