Answer:

The answer to your question is 20 in

Step-by-step explanation:

Data

ratio  1 : 30

real length = 55 ft

toy train length = ?

Process

1.- Use ratio and proportions to solve this problem.

                           1 : 30 :: x : 55

solve

                           x = (55 x 1) / 33

Simplification

                           x = 55/33

result

                           x = 1.67 ft

2.- Convert the length to in

                         1 ft ------------------ 12 in

                        1.67 ft --------------   x

                          x = (1.67 x 12) / 1

-Simplification

                          x = 20/1

-Result

                           x = 20 in

natita [175]

Answer:

7i

Step-by-step explanation:

We know that  i = √-1

Then solving the given:

  • √-49 = √49×(-1) = √49 × √-1 = 7×√-1 = 7i

So the answer is:

  • √-49 = 7i

Explain why f(x) = x2+4/x2-x-2 is not continuous at x = 2.
xxTIMURxx [149]

Answer: Option a.

Step-by-step explanation:

 Make the denominator equal to zero and solve for x:

Factor the quadratic equation. Find two number whose sum is -1 and whose product is -2. Then:

x^{2}-x-2=0\\(x-2)(x+1)=0\\x=2\\x=-1

Then, as you can see the value x=2 makes the denominator equal to zero and the division by zero does not exist. Therefore you can conclude that the function shown in the problem is not defined at x=2

The answer is the option a.

A 12- foot ladder that is leaning against a wall makes a 75.5 degree angle with the level ground
viktelen [127]

Answer:option C is the correct answer.

Step-by-step explanation:

When the ladder leans against the wall, it forms a right angle triangle with the wall. The length of the ladder becomes the hypotenuse of the right angle triangle.

Since the length of the ladder is 12 foot, then

Hypotenuse = 12 foot

The angle formed by the ladder with the ground is 75.5 degrees. Therefore, the height, y which is the distance from the point where the ladder touches the wall to the foot of the wall becomes the opposite side. It would be determined by applying trigonometric ratio

Sin θ = opposite side/hypotenuse

Sin 75.5 = y/12
