Answer: D
Step-by-step explanation:
so we know the probability of drawing a 9 is 25 percent or 1/4 because 9 is only one and doesn't repeat.
So the cards we drawn cards we drawn 2 times so multiply 1/4 times two.
1/4 * 2/1= 2/4 = 1/2
Answer:
1 and 1/3 of the sandwiches are left over.
Step-by-step explanation:
To show your work, start by drawing 4 squares or circles. In each shape, split it into 3 parts. Now shade 8 parts out of all shapes. Your answer will be right in front of you. Hope this helped you. :)
Answer:
The volume of the cylinder is 6,104.16 square meters.
Step-by-step explanation:
Given that a cylinder has a height of 6 meters and a diameter that is 6 times the measure of the height, to determine, using 3.14 for pi, which of the following can be used to calculate the volume of the cylinder, the following calculation must be done, knowing that the volume of a cylinder is determined by multiplying Pi by the height by the radius squared, and that the diameter of a circle is twice its radius:
3.14 x 6 x (6x3) ^ 2 = X
18.84 x 18 ^ 2 = X
18.84 x 324 = X
6,104.16 = X
Therefore, the volume of the cylinder is 6,104.16 square meters.
The answer is B) divide 124 by 275
Answer:
It will take 554 years
Step-by-step explanation:
Here, we want to estimate the time when t will be $50
We can rewrite the exponential equation as;
y = 200(1-0.0025)^t
In this case, y = $50 and we want to calculate t
so, we simply proceed to substitute the value 50 for y
we have this as ;
50 = 200(1-0.0025)^t
50/200 = (1-0.0025)^t
1/4 = 0.9975^t
0.25 = 0.9975^t
Take the natural logarithm of both sides
ln 0.25 = ln 0.9975^t
ln 0.25 = t ln 0.9975
t = ln 0.25 / ln 0.9975
t = 553.8 = 554 years
The bike will be $50 in 554 years
