The answer is A

One revolution is equal to the circumference of the tire:

C=2pi r=2(1)(frac{22}{7})=\frac{44}{7}

The car travels at 4,400 ft per minute. To calculate the number of revolutions, divide the speed by the circumference:

4,400div frac{44}{7}=4,400times frac{7}{44}=700

700 revolutions.

16. The open circle is excluded and closed is included.
x≤-6
x>2

17. The open circle is excluded so the inequality would be: -3<x<2

Find x (Will mark brainliest if you are right)

Marizza181 [45]

Answer:

Step-by-step explanation:

(-3x + 2)(45x + 21) + (-4x + 25) = 50

-135x^2 - 63x + 90x + 42 - 4x + 25 = 50

-135x^2 + 23x + 67 = 50

-135x^2 + 23x + 67 - 50 = 0

-135x^2 + 23x + 17 = 0

quadratic formula : x = (-b ± √b^2 - 4ac)/2a

a = -135, b = 23, c = 17

x = -23 ± √23^2 - 4(-135)(17) / (2(-135)

x = (-23 ±√9709 )/ -270

x = 23/270 ± 1 / 270√9709/270

x = 0.4501 or x = - 0.2798 <=== these answers are rounded

What is the quotient StartFraction 15 p Superscript negative 4 Baseline q Superscript negative 6 Baseline Over negative 20 p Sup

Kitty [74]

Answer:

$-\frac{3p^8}{4q^3}$

Step-by-step explanation:

$\frac{15p^{-4}q^{-6}}{-20p^{-12}q^{-3}}$ can be broken down into three fractions, coefficients, powers of p, powers of q.

$-\frac{15}{20}\cdot\frac{p^{-4}}{p^{-12}}\cdot\frac{q^{-6}}{q^{-3}}$

Simplify the first fraction, then simplify the others by subtracting numerator exponents minus denominator exponents.

$-\frac{3}{4} p^{-4-(-12)} q^{-6-(-3)} =-\frac{3}{4} p^8 q^{-3} = \alpha -\frac{3p^8}{4q^3}$
