Answer: 1/17
Step-by-step explanation:
First and foremost, we should note that there are 13 diamonds in a standard deck of 52 cards.
If the first card is drawn, the probability of picking a diamond is 13/52. Since it's not replaced, when another one is picked, the probability that it will be diamond will be 12/51.
We then multiply both together. This will be:
= 13/52 × 12/51
= 1/4 × 4/17
= 1/17
Answer:
x = -6
Step-by-step explanation:
5x² + 60x + 180 = 0
5 x 180 = 900
you need 2 numbers that multiplies into 900 and adds into 60. these numbers are 30 and 30. now we can rewrite it
5x² + 30x + 30x + 180 = 0.
split it in half and factorise
5x(x + 6) + 30(x + 6) = 0
this means the brackets are:
(5x + 30)(x + 6) = 0
5x + 30 = 0
5x = -30
x = -6
x + 6 = 0
x = -6
therefore, x = -6.
Answer:
The lengths of the legs of a right triangle are 15 meters each. The length of the hypotenuse of a right triangle is 50 inches.
Step-by-step explanation:
Here is thetower it is talking about (illistration)
Answer:
100/3 cubic feet.
Step-by-step:
In this case, if you observe the sphere, the height is simply two times the radius.
The formula to find the volume of a sphere is π * r^2 * h. The height is basically just 2r. And so, the edited formula becomes π * r^2 * 2r = 2 * π * r^3.
2 * π * r^3 = 50
π * r^3 = 25
r^3 = 7.957747155
r =
r = 1.996472712
Now that we have the measure of the radius, we can find the volume of the sphere!
(4 / 3) * π * r^3
(4/3) * π * (1.996472712)^3
= (4/3) * π * 7.957747155
= (4/3) * π * (25 / π)
= (4/3) * 25
= 100/3 cubic feet.
Hope this helps!
Answer:
B) 18
Step-by-step explanation:
- 25 + 17 = 42
- 37 - 13 = 24
- Put them together: 42 - 24
- 42 - 24 = 18
I hope this helps!
