Step-by-step explanation:

4w (w - 3) = 24

4w^2 - 12w = 24

4w^2 - 12w - 24 = 0

use calculator, EQN if using Casio

the answer will be

In the first game of the year, the modified basketball team made 63.5% of their foul shot free throws. Matthew made all 6 of his

SVETLANKA909090 [29]

So 6 shots equal 25% of the teams total shots(x)
So 6= 0.24(x)
X = 6/0.25
X= 24

If the team made 62. 5% of their shots then they missed 100% - 6.25% = 37.5 %
37.5 % of 24 = 24(0.375) = 9

Two lighthouses are located 60 miles from one another on a north-south line. If a boat is spotted S 21o E from the northern ligh

jasenka [17]

Answer:

(A)The northern lighthouse is 8.2 miles closer than the southern lighthouse.

Step-by-step explanation:

The triangle attached represents the given problem.

First, let us determine the distance of the Boat from each of the lighthouse.

In Triangle ABC,

∠A+∠B+∠C=180 degrees

21+∠B+16=180

∠B=180-37=143 degrees.

Using Law of Sines

$\frac{a}{Sin A}=\frac{b}{Sin B}\\\frac{a}{Sin 21^0}=\frac{60}{Sin 143^0} \\\text{Cross Multiply}\\a*sin143=60*sin21\\a=60*sin21\div sin143\\a=35.73 miles$

Similarly

$\frac{c}{Sin C}=\frac{b}{Sin B}\\\frac{c}{Sin 16^0}=\frac{60}{Sin 143^0} \\\text{Cross Multiply}\\c*sin143=60*sin16\\c=60*sin16\div sin143\\c=27.48 miles$
