Answer:

Step-by-step explanation:

Since the triangle is right use the tangent ratio to find x

tan64° = $\frac{opposite}{adjacent}$ = $\frac{x}{11}$

Multiply both sides by 11

x = 11 × tan64° = 22.55 → B

Find the 46th term 10,17,24

notsponge [240]

Answer:

325

Step-by-step explanation:

Notice you are adding 7 everytime.

So the sequence would be:

a(n) = 10 + 7n

n=0 gives a(0)=10, which is the first term.

so the 46th term has n=45.

a(45)=10 + 7*45=325

Kelly drove north for 9 miles and then east for 12 miles at an average rate of 42 miles per hour to arrive at the town of Prime.

mr_godi [17]

Answer:

Step-by-step explanation:

This is one of the more interesting motion problems I've seen. I like it! If Kelly is driving north (straight up) for 9 miles, then turns east (right) and drives for 12 miles, what we have there are 2 sides of a right triangle. The hypotenuse is created by Brenda's trip, which originated from the same starting point as Kelly and went straight to the destination, no turns. We need the distance formula to solve this problem, so that means we need to find the distance that Brenda drove. Using Pythagorean's Theorem:

$9^2+12^2=c^2$ and

$81+144=c^2$ and

$225=c^2$ so

c = 15.

Brenda drove 15 miles. Now we can fill in a table with the info:

d = r x t

Kelly 12+9 42 t

Brenda 15 45 t

Because they both left at the same time, t represents that same time, whatever that time is. That's our unknown.

If d = rt, then for Kelly:

21 = 42t

For Brenda

15 = 45t

Solve Kelly's equation for t to get

t = 1/2 hr or 30 minutes

Solve Brenda's equations for t to get

t = 1/3 hr or 20 minutes

That means that Brenda arrived at the destination 10 minutes sooner than Kelly.

You and your friend are playing a game where you spin a circular spinner with nine numbered sections of equal size. In this game

Phoenix [80]

Answer:

a) The subset consists of all the outcomes where your friend loses or there is a tie.

d) The subset consists of all the outcomes where you do not lose.

Both are correct.

Step-by-step explanation:

The subset A= { 1,3,4,6,7,9} removes 2,5 and 8 from the sample space of the game. Those three numbers are the ones for which your friend wins, therefore, the subset consists of all outcomes for which you either win (your friend loses) or there is a tie.

Checking the given alternatives, there are actually two correct ones. Alternatives a) and d) describe the same sample space (you not losing = your friend not winning).

Therefore, the two possible answers are:

a) The subset consists of all the outcomes where your friend loses or there is a tie.

d) The subset consists of all the outcomes where you do not lose.
