Answer:
the answer is DBC=90°
because the midpoint of the perimeter of quadrilateral is B
Answer:
<u> -54.5%</u>
Step-by-step explanation:
You will have to use this formula
When substituted in you have 
30-66=-36
-36/66= -0.54 (54 repeating)
Then you have to convert this into a percentage, -54.54(repeating) percent
To the nearest hundredth you would round down to<u> -54.5%</u>.
It is a Decrease because it is negatated.
Answer:
C. 150
Step-by-step explanation:
The number of people who took the test is unknown, so call it x.
34% of x liked the flavor.
51 people liked the flavor.
That means that 34% of x is equal to 51.
34% of x = 51
0.34x = 51
x = 51/0.34
x = 150

Answer:
V=3926.99 liters
Step-by-step explanation:
cylindrical Is half full of oil The cylinder Has a base radius of 100 cm The height of the cylinder 250cm 1 litres = 1000cm3 How many litres of oil are in the tank?
Volume of a cylinder can be calculated using below formula
V=π r^2 h
Where r= radius
h= height
radius = 100 cm
h=250cm
But the cylinder is half filled, then the formula becomes
V=(π r^2 h) × 1/2
Then substitute the values we have
V=( π × 100^2 ×250) × 1/2
V=3926990 cm^3
But 1 litres = 1000cm3
Then V=(3926990 cm^3)/ 1000
V=3926.99 liters
