Answer:

none of them are true, but if you could re copy and paste and delete all of the spaces, I can make 100% sure because I could've did something wrong with it looking like this.

24.8/ 102= 0.243

34.65/ 1,000= 0.03465

193.5/100= 1.935

6.24/10= 0.624

160.4/ 102= 1.5725

these are the equations in the problem with their actual answers, none of them match the ones provided

Step-by-step explanation:

June will spin the arrow on the spinner 5 times. What is the probability that the arrow will stop on A, then B, then C, then D,
inessss [21]
Ok so assuming the board only has 4 spaces to land on (A,B,C,D) all we need to do is weight the probability, 

1/4 x 1/4 x 1/4 x 1/4 x 1/4 = 1/1024 

To solve I put the number of favorable outcomes over the number of total outcomes, in this case we had 1 favorable outcome each time and a constant of 4 possible outcomes.

Frank stands 500 feet from the base of the Statue of Liberty. If Frank looks up with an angle of elevation of 30', how tall is t
Over [174]
Answer: 289 ft.

Explanation:

You can form a right triangle with these features:

1) Base = adjacent-leg = 500 feet

2) angle between the hypotenuse and the base = 30° ( I use 30° instead of 30', because 30' does not make sense, it is a too small angle)

3) Height = opposite-leg = height of the Statue of LIberty = x

Now, use the equation for the trigonometric ratio tangent:

tan(angle) = opposite-leg / adjacent-leg

=> tan (30°) = x / 500ft

=> x = 500ft * tan(30°)

x = 288.67 ft which rounded to the nearest foot is 289 ft.

(50 points!) Whats 7x + 5z(x-z) ÷ 9y, when x = 5, z = 8, and y = 23. Whoever Gives me an answer AND REALLY GOOD EXPLANATION FIRS
Oliga [24]

Answer: First we will substitute the numbers given for the variables.

Then we will use order of operations to simplify.

7x + 5z(x - z) ÷ 9y would be equal to

7(5) + 5(8) * (5 - 8) ÷ 9(23)

Simplify:

35 + 40(-3) ÷ 207

Use order of operations to multiply 40 and -3; the equation now looks like:

35 + (-120) ÷ 207

Use order of operations to divide -120 and 207; the equation now looks like:

35 + (-0.6)

Add 35 and -0.6:

34.4

The solution to this equation is 34.4.
