Answer:

480

Step-by-step explanation:

We can set up a proportion:

#students that eat carrots / #students surveyed=#students that eat carrots / #students surveyed

x will equal the number of students in Sarah's school who eat carrots.

30/50 = x/800

We can simplify

3/5=x/800

We cross multiply

5x=3*800

5x=2400

x=480

Hope this helps!

The area of the larger rectangle is 40.32 cm²

Step-by-step explanation:

4.8/4 = x/7

where x is the length of the base of the larger rectangle.

x = (4.8/4)*7

x = 8.4 cm

The area of the larger rectangle is:

A = base*height

A = 8.4*4.8

A = 40.32 cm²

<h3>How to calculate a ratio.</h3>

In this exercise, you're required to share the total amount of money in the ratio of 3:7. Thus, we would solve as follows:

For a ratio of 3:

$Amount=\frac{3}{10} \times 900\\\\Amount=\frac{2700}{10}$

Amount = £270.

For a ratio of 7:

$Amount=\frac{7}{10} \times 900\\\\Amount=\frac{6300}{10}$

Amount = £630.
