dusya [7]3 years ago

Answer:

65 degrees

Step-by-step explanation:

Since it is given that AB=DC

then we know that AO=DO and BO=CO because it is the radius of a same circle.

Hence the shapes are equal and thus DOC=65 degree as it serves as a corresponding angle to AOB

help pleaseeee, i managed to get the right answer but the way i did it doesnt feel right, can somebody please answer so i can se
irga5000 [103]

Answer:

≈ 4,22 m

Step-by-step explanation:

volume = 20000L = 20000 dm^3 = 20 m^3

diameter = 2,4m

the volume of a cilinder is π * r^2 * h (height)

20 = π * 1,2^2 * h

h = \frac{20}{\pi * 1,44} \\ ≈ 4,42 m

Slope=
elixir [45]

Point 1 (0, - 2)

Point 2 (8,0)


Slope = (y2-y1)/(x2-x1)= (0-(-2))/(8-0)=2/8=1/4

y-intercept (from the Point 1 (0, - 2)) is -2.


Equation : y=(1/4)x - 2


Coordinates to test are (4,-1).


y=(1/4)x - 2

-1=(1/4)*4 -2

-1=1-2

-1=-1 True

Mrs William has a prized box with different colored tickets. Each ticket results in different type of prize.
Lera25 [3.4K]

\text{ Answer:} \text{ Probability that he chooses a yellow ticket and then a purple ticket }= \frac{3}{25}

Step-by-step explanation:

Since we have given that

Number of green tickets =3

Number of yellow tickets = 4

Number of purple tickets = 3

Total number of tickets = 3+4+3=10

Now,

As we know that Pedro select a ticket and replace it and then select another ticket , total number of outcomes will never change it will be 10 only for each case.

Probability that he chooses a yellow ticket and then a purple ticket is given by

\frac{4}{10}\times \frac{3}{10}\\\\=\frac{12}{100}\\\\=\frac{3}{25}
