PLEASE EXPLAIN!!!

1 answer:

8 0

The easiest thing to do is convert all the measurements to yards...
18ft = 6 yards
6 inch = 1/6 yard ( 6 inches = 1/2 ft.... so 1/6 yard)
so the volume is V = 6 x 6 x 1/6
Then all you do is calculate the cost. I hope this helps you out

Find A and C,Laws of sines and cosines

stealth61 [152]

Answer:

$AC=15.9976$

Step-by-step explanation:

Law of Sines: $\frac{sin(A)}{a} =\frac{sin(B)}{b} =\frac{sin(C)}{c}$

Step 1: Define

a = 8 ft

A = 30°

b = ?

B = 89°

Step 2: Substitute and Evaluate

$\frac{sin(30)}{8} =\frac{sin(89)}{b}$

$bsin(30)=8sin(89)$

$b=\frac{8sin(89)}{sin(30)}$

$b=16cos(1)$

$b=15.9976$

$AC=15.9976$

Does the line whose equation is y=-2x+13 pass through the point (4,5)? Explain how you arrived at

katrin2010 [14]

Answer:

Yes

Step-by-step explanation:

Plug in 4 for x, 5 for y. if it equals, then its a point

5 = -2(4) + 13

5 = -8 + 13

5 = 5

it equals so (4,5) is a point

Y= 3x-1 2x+6=y substitution method

vfiekz [6]

Answer: (7, 20)

Concept:

There are three general ways to solve systems of equations:

Elimination
Substitution
Graphing

Since the question has specific requirements, we are going to use substitution to solve the equations.

Solve:

Given equations

y = 3x - 1

2x + 6 = y

Substitute the y value since both equations has isolated [y]

2x + 6 = 3x - 1

Add 1 on both sides

2x + 6 + 1 = 3x - 1 + 1

2x + 7 = 3x

Subtract 2x on both sides

2x + 7 - 2x = 3x - 2x

$\boxed{x=7}$

Find the value of y

y = 3x - 1

y = 3(7) - 1

y = 21 - 1

$\boxed{y=20}$

Hope this helps!! :)
