Answer:

The angle complies with the state regulations.

Step-by-step explanation:

The angle of elevation is the angle \theta in the figure, and from trigonometry we find that

sin(\theta) = \dfrac{1.5ft}{25ft}

taking the inverse sine of both sides we get

\theta = sin^{-1}(\dfrac{1.5ft}{25ft})

which gives

\theta = 3.44^o

which is less than 5°, and therefore is well within the state regulations.

Before recess, Marcy has math class for 1 hour and 50 minutes. Recess lasts for 30 minutes and ends at 11:55 A.M. What time does
Temka [501]

Answer:

Marcy's math class starts at 9:35.

Step-by-step explanation:

11:05

  -30 = 10:35     This gets rid of the 30 minutes of recess.

Now subtract one more hour to subtract the remainder of math class, and you get 9:35. Marcy's math class starts at 9:35.

Ronald spins a spinner that has 10 sections numbered from 1 to 10. What is the probability that the spinner lands on a prime num
vladimir1956 [14]
Prime number is a whole number that has no possible divisors that 1 and itself. Prime numbers are 2, 3, 5.7.11,13,17,19,23 and 29. From 1 to 10 there are 3 prime numbers: 3,5 and 7. 
The probability can be calculated as the ratio between the number of "good" events and the total number of possible events. There are three "good" events (3,5 or 7) and 10 total events, so the probability that the spinner lands on a prime number is: 3/10. So, none of the given options is true.
