Answer:

144 un²

Step-by-step explanation:

Front Parallelogram = 5 x 11 = 55

Two triangles = 3 x 4 = 12

Back Parallelogram = 3 x 11 = 33

Bottom rectangle = 4 x 11 = 44

Total =

55 + 12 + 33 + 44 = 144

units = un²

144 un²

Question 1:

We can tell that this shape is a parallelogram because the diagonals bisect each other, which is a property unique to parallelograms.

Question 2:

72 + 72 = 144

This is not a right angle, so this shape cannot be a square or rectangle.

Since we have congruent base angles, each of those triangles are congruent isosceles triangles.

Thus, we have 4 sides of equal length. Thus, this shape must be a rhombus.

Question 3:

We know that AB and CD (the legs) are congruent since this is an isosceles trapezoid.

8y - 18 = 7y - 4

Subtract both sides by 7y

y - 18 = -4

Add both sides by 18

y = 14

That's your answer.

Have an awesome day! :)

The art club held a car wash on Saturday and Sunday. They washed a total of 50 cars. If they washed 30% of the cars on Sunday, h
o-na [289]

Answer:

If I did my math correctly, They washed 15 cars on Sunday.

Step-by-step explanation:

50 cars = 100%

Therefore 1 car would be 2% because 50 is half of 100.

So because 30% would be 2 times the amount of cars, we divide 30 by 2, giving us 30% = <u>15 cars on Sunday</u>

With this information, we can take away 15 from 50 giving us 35 cars which is equal to 70% on Saturday

Here is some extra data:

10% = 5 cars

20% = 10 cars

30% = 15 cars

40% = 20 cars

50% = 25 cars

60% = 30 cars

70% = 35 cars

80% = 40 cars

90% = 45 cars

100% = 50%

Basically, every 10% is +5 cars
