3 GBs per month because you have to take 30-21 (the monthly cost of the phone)=9 and each GB is $3 a month so 9 divided by 3= 3

Answer:

<u>Two equivalent fractions with whole numbers may be 180/150, or 6/5</u>

<u>The height of the tree is 39.6 feet.</u>

Explanation:

The diagram provides the proportion of the heights to the shadows:

$\frac{x}{33}=\frac{1.8}{1.5}$

From that you are asked (i) to simplify the fraction of the right side to one with whole numbers.

You can do that in two steps by multiplying both numerator and denominator by 10:

$\frac{1.8\times 10}{1.5\times 10}=\frac{180}{150}$

You can simplify that fraction if you divide by the greatest common factor of 180 and 150, which is 30:

$\frac{180/30}{150/30}=\frac{6}{5}$

The second part (ii) asks to find the height of the tree, that is x. To solve for x you can multiply both sides by the denominator of the fraction on the left and then simplify:

$\frac{x}{33}=\frac{6}{5}\\ \\ x=\frac{6\times 33}{5}\\ \\ x=\frac{198}{5}=39.6$

Thus, the height of the three is 39.6 feet.

The area of a square garden is 25 m2 how long is each side of the garden

Arisa [49]

Answer:

5 meters

Step-by-step explanation:

The area of a square is found by multiplying 2 sides.

If we already have the area, we can take the square root of it to find a side.

√25= 5

All of the sides of a square are the same, therefore each side of the garden is 5 meters long!
