Answer:

$\frac{7}{3}$

Step-by-step explanation:

csc(Ф) is equivalent to the inverse of sin(Ф)

$csc = \frac{1}{sin}$

Since sin(Ф) = 3/7, the inverse of this would be 7/3

So, $csc = \frac{1}{\frac{3}{7} }=\frac{7}{3}$

Virty [35]

Answer:

Marta need to score at least 94 to receive an average of 90 or higher considering all five tests.

Explanation:

Marks received by Marta in four tests = 86, 84, 97 and 89

Let mark received in fifth test be x

We have average of five test is more than or equal to 90

So we have

$\frac{86+84+97+89+x}{5} \geq 90\\ \\ 86+84+97+89+x\geq 450\\ \\ x\geq 94$

So Marta need to score at least 94 to receive an average of 90 or higher considering all five tests.

The local high school sold 1914 tickets this year to its spring musical. That was 174 more tickets sold than last year. What is

pantera1 [17]

Answer:

.909 (ROUNDED)

Step-by-step explanation:

In order to do this all you need to do is divide the number with the number you got this year, 1914, and with the number last year.

1914-174=1740

1740 was the amount they got last year

Now you want to find the percent difference between the two.

1740/1914=.909090 (Repeats)

So the percent increase would be

.909090

.101010
