Answer:

Of the basketball players on the team, exactly 75% of the players have heights above 180

Step-by-step explanation:

So, they are 12 basketball players in total

1 - 170 - This is 1/12

2 - 175 - This is 1/6

1 - 180 - This is 1/12

4- 185 - This is 1/3

3 - 190 - This is 1/4

1 - 195 - This is 1/12

75% (Or 3/4) have heights above 180

Therefore, the answer is B

What is the length of LJ?

Fofino [41]

Option D:

The length of LJ = 3.5

Solution:

In the triangle LJK,

LK = 9, ∠K = 23°, ∠J = 89°

To find the length of LJ:

<u>Law of sine: </u>

A, B, C are the angles of the triangle and

a, b, c are the sides of the triangle.

$$\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}$

Here for ΔLJK,

The side opposite to angle L is <em>l</em>.

The side opposite to angle J is <em>j</em>.

The side opposite to angle K is <em>k</em>.

$$\frac{l}{\sin L}=\frac{j}{\sin J}=\frac{k}{\sin K}$

Take only two sides.

$$\frac{9}{\sin 89^\circ}=\frac{LJ}{\sin 23^\circ}$

$$9\times \sin 23^\circ=LJ \times\sin 89^\circ$

$$9\times0.3907=LJ \times0.9998$

$$3.5163=LJ \times0.9998$

$$LJ=\frac{3.5163}{0.9998}$

$$LJ=3.51$

LJ = 3.5 (approximately)

Option D is the correct answer.

The length of LJ = 3.5.

Ms. Pacheco, Mr Edwards, and Mr Richards are three math teachers at turner middle school. Ms. Pacheco is three years older than

zubka84 [21]

Mr edwards = Mr r x 2
Mr r = Mr p - 3 = Mr e ÷ 2. Mr p = 30
Mr e + Mr r = 81. Mr e = 54
Mr p = Mr r + 3. Mr r = 27

Mr Edwards = 2(Mr p - 3)
Mr e = 2(mr p) - 6

Mr r = [2(Mr p) -6] ÷ 2
Mr r = [2( Mr r + 3) - 6] ÷ 2

2(Mr r) + (Mr p - 3) = 81
2(Mr p -3) + (Mr p - 3) = 81
3(Mr p - 3) = 81
3(Mr p) - 9 = 81. Hope this helps!!!
3(Mr p) + 9 = 81 + 9
3(Mr p) = 90
Mr p = 90 ÷ 3
Mr p = 30
