Answer:

136 square units

Step-by-step explanation:

Find all the areas of different shapes then add all together.

6*7=42 (the middle rectangle)

(5*7)*2=70 (two same rectangles on the sides.)

4*0.5*6*2=24(the area of two triangles)

24+42+70=136 square units

Hope this helps you!~ :)

The price of a watch was increased by 20% to £144. What was the price before the increase?

hammer [34]

Answer:

120 pounds

Step-by-step explanation:

Since the new cost is 144 pounds and this is 20% more, this is 120% of the original price. Remember 100+20 = 120. To find the original price set up a proportion with these values:

$\frac{144}{x}=\frac{120}{100}$

Solve for the original price by cross multiplying numerator with denominator.

x(120) = 144(100)

120x = 14400

x= 120 pounds

Answer:

4 quarters

10 tenths

Step-by-step explanation:

<h3>Tenths</h3>

$\frac{1}{10}$

<h3>Quarter</h3>

$\frac{1}{4}$

<h3>Whole</h3>

$1$

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

$1 = \frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}$

∴ There are <u>4</u><u> </u><u>quarters</u> to make a whole

$1 = \frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}$

∴ There are <u>10</u><u> </u><u>tenths</u><u> </u>to make a whole
