Answer:

1/12 or 8.33% is the probability

Step-by-step explanation:

Assuming the number cube has 6 sides there is 1/6 chance of getting a 3 and a 1/2 chance of getting tails when flipping a coin. Multiplying 1/6 by 2 to get 1/12.

Celeste wants to have her hair cut and permed and also go to lunch she knows she will need $50 the perm cos twice as much as her

e-lub [12.9K]

Lets say the cost of her haircut is $x. This makes the cost of her perm 2x (twice as much). If lunch ($5), the perm ($2x) and the haircut ($x) cost, in total, $50, we can say:

50 = 5 + 2x + x
Combine like terms:
50 = 5 + 3x
Subtract 5 from both sides to isolate 3x
50 - 5 = 3x
45 = 3x
Divide all by 3 to isolate x
x = 45/3
x = 15

So the haircut is $15 and the perm is $30 (2*$15).

From the hay loft door, Ted sees his dog on the ground. The angle of depression of the dog is 40º. Ted's eye level is 16 feet ab

Answer: 19 feet

Step-by-step explanation:

Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.

Tan α = opposite side / adjacent side

Where α is the angle of depression of the dog, the opposite side (16) is Ted's eye level above the ground, and the adjacent side (x) is the distance between the dog and the barn door.

Replacing with the values given:

tan40 = 16/x

Solving for x

x =16/tan40

x= 19 ft

What do you know about Mexico? 5 sentences

Paul [167]

Mexico could be a nation with no memory and in this way unused all the time. Conventions are strengths of nature, and history is simply a story for excitement, for one cannot learn from it The same histories of debasement, the same stories of achievement, the story of the ones who accomplish enormity somewhere else proliferates.
