Answer:
4
Step-by-step explanation:
BCD is a right triangle. The Pythagorean Theorem applies; a^2 + b^2 = c^2, with c being the hypotenuse. a^2 + 9 = 25, so a^2 = 16, so a = 4
Answer: In explanation
Step-by-step explanation: 350-170=4x
Solve 180=4x
45=x 45 minutes longer
4x+170=350 because you would want to subtract 170 from each side not add 170 to each side when simplifying
4x+170 because that is how much gas the tank can hold. You need to have 4x in the equation and 350 and 4x wouldn't make sense so use 4x and 170.
45 minutes as stated above.
<span>Answer:
(13 ranks, choose 2)*(4 from each rank, choose 2)
*(remaining 44 cards, choose 1) /(52 total, choose any 5)
= 13c2*(4c2)^2 *44 / 52c5 = 0.0475</span>
Answer:
3rd option
Step-by-step explanation:
The area (A) of a semicircle is calculated as
A = 
πr² ( r is the radius )
Here diameter = 44, so r = 44÷ 2 = 22
Then
A = π × 22² =
