Answer:

Side x is adjacent to 30° angle.

<u>Correct method is:</u>

  • cos 30° = x/15 ⇒ x = 15*cos 30° ⇒ x = 12.99

Diego is correct and Steven is wrong.

  • when finding <u>sine</u> consider the <u>opposite side to the angle</u>, not hypotenuse
  • when finding <u>cosine</u> consider <u>adjacent side to the angle,</u> not hypotenuse

-3(x+5)=3(x-1) How to solve
Luden [163]

Answer:

x = -4

Step-by-step explanation:

-3 (x + 5) = 3 (x - 1)   <Start by distributing the -3 and 3 (don't forget to distribute     .                                  the negative symbol!

-3x - 15 = 3x - 3

+3x          +3x   <Add 3x on both sides

-15 = 3x - 3

+3        +3   <Add 3 on both sides

-12 = 3x   <Divide by 3 on both sides

-4 = x

Given 3p+2q=3 and 6p+8q=2 solve for q and p simultaneously
ASHA 777 [7]

Answer:

Slope = -5.000/2.000 = -2.500

 p-intercept = 2/15 = 0.13333

 q-intercept = 2/6 = 1/3 = 0.33333

Step-by-step explanation:

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  -15p - 6q + 2  =   -1 • (15p + 6q - 2)

Equation at the end of step  1  :

Step  2  :

Equation of a Straight Line

2.1     Solve   -15p-6q+2  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axi

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  -15p-6q+2  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when p = 0 the value of q is 1/3 so this line "cuts" the q axis at q= 0.33333

 q-intercept = 2/6 = 1/3  =  0.33333

Calculate the X-Intercept :

When q = 0 the value of p is 2/15 Our line therefore "cuts" the p axis at p= 0.13333

 p-intercept = 2/15  =  0.13333

Calculate the Slope :

Slope is defined as the change in q divided by the change in p. We note that for p=0, the value of q is 0.333 and for p=2.000, the value of q is -4.667. So, for a change of 2.000 in p (The change in p is sometimes referred to as "RUN") we get a change of -4.667 - 0.333 = -5.000 in q. (The change in q is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -5.000/2.000 = -2.500

Geometric figure: Straight Line

 Slope = -5.000/2.000 = -2.500

 p-intercept = 2/15 = 0.13333

 q-intercept = 2/6 = 1/3 = 0.33333

a ticket to the circus cost $7 for children's. Adult ticket cost $3 more. If a family with 2 adult 3 children buy ticket, what i
Elan Coil [88]
X = number of adult tickets
7x = value of the adult tickets

3x = number of child tickets
3x * 3 = value of children's tickets, which is also 9x

Value of adults plus value of children's = 6000

7x + 9x = 6000
Combine terms
16x = 6000
Divide by 16
x = 6000/16
Simplify fraction
x = 3000/8 = 1500/4 = 750/2 = 375 = number of adult tickets

Number of children's tickets = 3 * 375 = 1125 = number of children's tickets

Check:
Adults = 375 * 7 = 2625
Children's = 1125 * 3 = 3375
Total = 6000
