<h2>Option B:</h2><h3>112 families </h3>

Step-by-step explanation:

Given,

No. of families = 75

Out of 75 no. of families had cars = 42

Out of 1, no. of families can have cars

$= \frac{42}{75}$

Therefore, 

Out of 200 families, no. of families had cars

$= 200 \times \frac{42}{75}$

$=200 \times \frac{14}{25}$

= 8 × 14

= 112

Hence,

32 is 90% of what number?

spayn [35]

Answer:

$\large\boxed{32\ is\ 90\%\ of\ 35\dfrac{5}{9}}$

Step-by-step explanation:

<h3>METHOD 1:</h3>

$\begin{array}{ccc}32&-&90\%\\\\x&-&100\%\end{array}\qquad\text{cross multiply}\\\\\\90x=3200\qquad\text{divide both sides by 90}\\\\x=\dfrac{3200}{90}\\\\x=\dfrac{320}{9}\\\\x=35\dfrac{5}{9}$

<h3>METHOD 2:</h3>

$\begin{array}{cccc}32&-&90\%&\text{divide both sides by 9}\\\\\dfrac{32}{9}&-&10\%\end{array}\\\\\\90\%+10\%=100\%\to32+\dfrac{32}{9}=32+3\dfrac{5}{9}=35\dfrac{5}{9}$

A total of 41 people attended Rayleigh's birthday party. Rayleigh's sister invited some of the guests. If Raleigh invited 19 mor

Keith_Richards [23]

Her sister invited 22 guests. What you have to do to solve this problem is subtract 41-19. We have to do this because Rayliegh invited 19 more people than her sister, but invited a total of 41 people herself. So, to figure out how many people her sister invited we have to know that Rayliegh invited 19 more people and we have to subtract that from the total number she invited to get how many people her sister invited: 22 guests. Can you make me brainliest?
