Answer 1

Answer: Do you have answer options for this question?

Answer:

The area of figure ABCD is:

24 square units.

Step-by-step explanation:

We see that the given points form the vertices of a trapezium ABCD with bases AD and CB with measure,

AD= 3 units

and CB=5 units

and the height of the trapezium is: AB= 6 units.

Hence, the area of trapezium ABCD is:

$Area=(1)/(2)* (AD+CB)* AB\n\n\nArea=(1)/(2)* (3+5)* 6\n\n\nArea=(1)/(2)* 8* 6\n\n\nArea=24$

Hence, the area of figure ABCD is:

24 square units.

240 is 60% of what number

Answers

60% * x = 240

60/100 * x = 240

6/10 * x = 240

3/5 x = 240 / : 3/5

x = 240 : 3/5

x = 240 * 5/3

x = 80 * 5

x = 400

Answer:

400

Explanation:

Assume that the number we are looking for is x

We know that:

60% of this number is 240

This means that:

60% * x = 240

0.6x = 240

x = $(240)/(0.6)$

x = 400

Hope this helps :)
