Answer:
15.6
Step-by-step explanation:
the traingle is right so u have to apply the pythagorean theorem to find x so x^2=10^2+12^2=244
so x=15.6
Answer:
64 photographs
Step-by-step explanation:
432 ÷ 92 = 4.695
Since the whole number in the answer is 4, multiply it with 92.
92 x 4 = 368
After that, minus it with all the photographs he have.
432 - 368 = 64
(Final answer)
That is how much photographs have to be partially filled.
Well, I dont think that amount of money is a real amount so.
But my guess would be $8.60
Explanation:
Since you provided us with 5,9, and 7, you should use the 7 to round up the next number. So, you round the 9, to 10, so you add the 1 from the 10, on the 5. So it is 6. So your answer is $8.60.
Check the forward differences of the sequence:
22 - 8 = 14
50 - 22 = 28 = 2*14
106 - 50 = 56 = 4*14
218 - 106 = 112 = 8*14
442 - 218 = 224 = 16*14
The differences are the products of increasing powers of 2 and 14:
and so on, with
Then the sequence has the recursive definition,
Answer:
Speed of plane in still air: 490 mile/hour
speed of wind: 70 mile/hour
Step-by-step explanation:
still speed = x wind speed = w
with wind: speed = still + wind
(x+w) * 3 = 1680 ...a
against wind: speed = still - wind
(x-w) * 4 = 1680 ...b
b-a ... 4x-4w-3x-3w = 0
x-7w = 0
x = 7w
substitution: (7w+w)*3 = 1680 8w = 560 wind speed (w) = 70
still speed (x) = 7w = 490 mile/hour
