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! :)
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
You use the cricle fourmla (πr sqaure). and you will get 7.065
