Find the number that belongs in the green box. <br><br>round your answer to the nearest tenth.

Delicious77 [7]

Answer:

4.6

Step-by-step explanation:

Use sine rule to find the number that belongs to the box.

Thus:

$\frac{a}{sin(A)} = \frac{b}{sin(B)}$

a = ?? (the number in the green box)

b = 5

A = 38°

B = 42°

Plug in the values

$\frac{a}{sin(38)} = \frac{5}{sin(42)}$

Multiply both sides by sin(38)

$\frac{a}{sin(38)} \times sin(38) = \frac{5}{sin(42)} \times sin(38)$

$a = \frac{5 \times sin(38)}{sin(42)}$

$a = 4.6$ (nearest tenth)

A Woman Leaves Home And Walks 3 Mi. West, And Then 2 Mi. South. What Is The Magnitude Of Her Displacement, and what direction mu

mojhsa [17]

Answer: 4 Mi Northeast

Step-by-step explanation:

west points left on a compass, and x points left on a graph so the value becomes x ⇒ ( 3x )
south points down on a compass, and y points down on a graph so the value becomes y ⇒ ( 2y )

Equation: $V=3x +2 y$

Solving Steps:

1. take the sum of the square of each vector component

$3^2 + 2^2 = 9 + 4 = 13$

2. take the square root of the result from from the last step

$\sqrt{13}=3.60555127546$

3. round to nearest whole number as told in your question

60555127546 ⇒ 4

4. find direction to go with number

- opposite of west is east

- opposite of south is north

direction is northeast

========================

ans = 4 Mi Northeast

Pleas Help!? I am confused......

IrinaVladis [17]

Notice the x^-2, this is equal to 1/x^2. Then notice the y^0, any value raised to the zero power is equal to 1, ie n^0=1. So your expression is actually just:

8/x^2, the y value has no effect upon the output. They want you to evaluate, which must means calculate, the value when x=2 so:

8/(2^2)

8/4

Hey 1200 seat theater sells two types of tickets for a concert. premium seats sell for $30 each and regular seats so for $20 eac

STatiana [176]

X = premium seats
y = regular seats
You need two equations: (x + y - 10 = 1200) and (30x + 20y = 30,180)
1.) Isolate one variable
y = 1,210 - x
2.) Plug the new equation into the second ORIGINAL equation
30x +20(1,210 - x) = 30,180
3.) Ditribute
30x + 24,200 - 20x = 30,180
4.) Add like terms
10x + 24,200 = 30,180
5.) Subtract 24,000 from either side
10x = 6,180
6.) Solve for x
x = 618
7.) Plug in x to the equation of your choosing
618 + y - 10 = 1200
8.) Solve for y
608 + y = 1,200
y = 592
The theater sold 592 regular seats and 618 premium seats.
