Eight people go to a movie. Adult tickets cost $15 and children's tickets cost $8
Reptile [31]

Answer: number of adults = 3, number of children = 5

Step-by-step explanation:

let the number of adults be x, and the number of children be y.

x + y = 8 , 15x + 8y = 85

1st equation x 8 = 8x + 8y = 64

8x+8y-15x-8y = 64 - 85\\-7x = -21\\x=3

substitute x=3

3+y=8\\y=5

David borrowed $30,000 to start a business. Four years later he repaid $1260 in interest. What was the annual rate? Round to two
ollegr [7]
Annual rate = 1.05%

Simple interest formula is I = Prt * 100
Where P is principle, I is interest, r is rate and t is time.

Transpose to make r the subject

Prt * 100 = I
r = I/ Pt * 100

Substitute values into the equation.
Let I = $1260, P = $30,000 and t = 4 years

r = $1260/ $30,000 * 4 * 100
r = 0.0105 * 100
r = 1.05%

Find the cosine of R.
JulijaS [17]

Answer:

cos(R) = \frac{\sqrt{15}}{5}

Step-by-step explanation:

To find the cosine of <R, apply the following trigonometric ratio formula:

cos(R) = \frac{adjacent}{hypotenuse}

Adjacent = 3

Hypotenuse = √15

Plug in the values into the formula

cos(R) = \frac{3}{\sqrt{15}}

Multiply the numerator and denominator by √15 to rationalize.

cos(R) = \frac{3 \times \sqrt{15}}{\sqrt{15} \times \sqrt{15}}

cos(R) = \frac{3\sqrt{15}}{(\sqrt{15})^2}

cos(R) = \frac{3\sqrt{15}}{15}

cos(R) = \frac{\sqrt{15}}{5}
