It means you divide $6$ with $\frac{3}{4}$ .

When you divide a fraction, you reciprocate it meaning divide it by $1$ or switch the numerator and the denominator. The reciprocated one will be: $\frac{4}{3}$

Multiply 6 with 4/3 and you get: $8$

$\frac{3}{4}$ goes $8$ times in $6$ :D

Answer:

x=5, and x=-2

Step-by-step explanation:

A point of intersection between the two would be when they equal each other:

x^2-3x-8=2

x^2-3x-10=0

(x-5)(x+2)=0

x=5, and x=-2

Find the unit rate for a runner in miles per hour who runs at a pace of 3/4 mile in 10minutes

yanalaym [24]

Answer:

$\large \boxed{\text{4.5 mi/h}}$

Step-by-step explanation:

A unit rate is the number of something there is per one unit of something else.

In this question, the unit rate is the number of miles per one hour.

1. Convert minutes to hours

$\text{time} = \text{10 min} \times \dfrac{\text{1 h}}{\text{60 min}} = \frac{1}{6} \text{ h}$

2. Find the unit rate

$\begin{array}{rcl}\text{unit rate} & = & \dfrac{\text{miles}}{\text{hours}}\\\\& = & \dfrac{\frac{3}{4}\text{ mi}}{\frac{1}{6}\text{ h}}\\\\& = &\dfrac{3}{4} \times \dfrac{6}{1}\text{ mi/h}\\\\& = & \dfrac{3}{2} \times\text{3 mi/h}\\\\& = & \textbf{4.5 mi/h}\\\end{array}\\\text{The unit rate is $\large \boxed{\textbf{4.5 mi/h}}$}$

Gimme the radius circumference and area<br> plsss i beg

Gala2k [10]

Answer:

radius = 5.75 units

circumference = 36.11 units

Area = 103.81625 square units

Step-by-step explanation:

Radius = 11.5 / 2 = 5.75

Circumference = 11.5 x 3.14 = 36.11

Area = 5.75 x 5.75 x 3.14 =

33.0625 x 3.14 =

103.81625 units square

This is all if pi = 3.14

Hope that helps!
