Answer:

a rule to know: a median divides the side into equal parts.

we know:

PR = -2a + 34

SR = 2a + 26

- based on the rule, SR is half of PR. in other words, PR is two times greater than SR.

so,

2SR = PR (now simply pluggin the expressions we have)

2(2a + 26) = -2a + 34 (solve the equation like any other equation prob.)

4a + 52 = -2a + 34

6a + 52 = 34

6a = -18

a = -3

- inorder to check if this is correct, simply reverse what we did. so pluggin the value of a to see if its correct.

Using the law of sines

sin 101 sin 38

--------- = ------------

42 p

Using cross products

p sin 101 = 42 sin 38

p = 42 sin 38 / sin 101

p=26.34175

In bowling, knocking down all of the pins with the first ball of a frame is called a strike. Roni is practicing bowling and gets

Nesterboy [21]

Answer:

$0.50 \leq \frac{x+2}{x+10}\\$

At least 6 strikes

Step-by-step explanation:

The required numerical data is missing from the question. In the original question, Roni gets a strike 2 out of 10 times and her goal is to have a minimum strike rate of 50%. The number of consecutive strikes required is given by the following inequality:

$0.50 \leq \frac{x+2}{x+10}\\$

Solving the inequality:

$0.5x+5 \leq x+2\\3\leq0.5x\\x\geq6$
