Answer:
13divided by 7
Step-by-step explanation:
X= 20 degrees. Your welcome if it were a little less sloppy it would probably make much more sense.
Answer:
5 ft/s
Step-by-step explanation:
Let L be the length of the ladder. The relation between the angle and distance X is:
X = L * sin θ the change of X will be:
dX/dt = L * cos θ If we evaluate the expression when θ = π/3, we get the change of X:
dX/dt = 10 * cos(π/3)
dX/dt = 5 ft/s
Answer:
d) 135º
Step-by-step explanation:
Note that the angle DCU is the sum of the angles DCB and BCU. The angle DCB is 90º because A B C D is a square, then all its angles are equal to 90º.
After attaching B U C to A B C D, we obtain a trapezoid A U C D. Since A U C D has at least one pair of parallel sides, then AU should be parallel to CD, thus the angle CBU must be 90º.
B U C is isoceles, so we conclude that other two angles must have the same size, and due to the sum of the angles of a triangle being 180º, then both BUC and BCU are equal to 45º
As a result, the angle DCU is equal to 90º+45º = 135º. Option d is the correct one.
Answer: (2p + 1.5d) + (5*(2)) = T
Step-by-step explanation: (2p + 1.5d) + (5*(2)) = T
Since there are no costs, i'll make up my own uwu;
Matinee = $5
Popcorn = $2
Drink = $1.5
T = total
(2p + 1.5d) + (5*(2)) = T
2p ($2 for each bag of popcorn - p represents popcorn)
1.5d ($1.5 for each drink, - d represents drinks)
5*2 ( 5 * 2 because we are already given the amount of matinee tickets they buy.
