Answer:
22 degrees
Step-by-step explanation:
The temperature rose for 10 hours between 4 am and 2 pm. At 3 degrees per hour, the rise is ...
(3 degrees/hour)(10 hours) = 30 degrees
Starting from -8 degrees, the temperature rose to ...
-8 +30 = 22 . . . degrees
Answer:
y = 4sin( π/12) + 5
Step-by-step explanation:
For a sinusidal function :
y = Asin(w + c) + s
Where ; A = amplitude ; w= angular velocity, s = vertical Displacement, c = phase angle
A = (maximum - minimum) / 2
A = (9 - 1) /2 = 8/2 = 4 feets
w = 2π/T ; T = 24
w = 2π/24 = π/12
s = (maximum - minimum) / 2
s = (9 +1) /2 = 10/2 = 5
c = 0
Plugging our values into the general equation :
y = Asin(w + c) + s
y = 4sin( π/12) + 5
Answer:
In bold below.
Step-by-step explanation:
let the shorter leg be x units long, then:
longer leg = x+4
and hypotenuse = x + x + 4 - 8 = 2x - 4 units.
By Pythagoras:
(2x - 4)^2 = x^2 + (x + 4)^2
4x^2 - 16x + 16 = x^2 + x^2 +8x + 16
2x^2 - 24x = 0
2x(x - 12) = 0
x = 12.
So the shorter leg = 12 units
Longer leg = 4 + 12 = 16 units and
Hypotenuse = 12 + 16 - 8 = 20 units.
Answer:
1/6
Step-by-step explanation:
Let E1 and E2 represent the empty cans and W1 and W2 be the cans filled with water.
S = { E1E2, E1W2,E2W2, E1W1, E2W1, W1W2 }
By merely guessing, the events are equally likely. Since there are 6 possible outcomes,
probability = 1/6
Okay, this is really easy:) He goes 3/8 miles and 1 and 3/8 miles. to add this together you just go across the top. Discard the 1 for a couple of seconds. so you have 3/8 + 3/8. Now go across the top so you get 6/8. simplify that, (divide by a common number, don't know if you know that or not) so, 2 in this case. you get 3/4. Your answer is 1 and 3/4. Hope this helps and isn't ridiculously confusing:) <span />
