Kayla runs 3/4 mile in 1/10 hour assuming she runs at a constant rate what is her speed in miles per hour

Vanyuwa [196]

Answer:

7.5 miles per hour

Step-by-step explanation:

Given: Kayla runs 3/4 mile in 1/10 hour assuming she runs at a constant rate

To find: speed in miles per hour

Solution:

Distance travelled by Kayla = $\frac{3}{4}$ mile

Time = $\frac{1}{10}$ hour

To find the speed in miles per hour, use the following formula:

Speed = Distance ÷ Time = $\frac{\frac{3}{4} }{\frac{1}{10} }=\frac{3}{4}(10)=7.5$ miles per hour

Solve the equation and show all work. 4|x + 1/3| = 20 i'm kind of stuck hhh

Absolute value is a function that takes some number and outputs the size of that number, regardless of the sign. By definition, $|x|=x$ if $x\ge0$ , and $|x|=-x$ if $x$ .

For example,

|2| = 2 because the input 2 is positive, so the input is unchanged;
|-3| = -(-3) = 3 because the input -3 is negative, so the sign is switched.

What this means for this problem is that there are two cases to consider:

If $x+\frac13\ge0$ , then $\left|x+\frac13\right|=x+\frac13$ , so that

$4\left(x+\dfrac13\right)=20\implies x+\dfrac13=5\implies\boxed{x=\dfrac{14}3}$

On the other hand, if $x+\frac13$ , then $\left|x+\frac13\right|=-\left(x+\frac13\right)$ , so

$-4\left(x+\dfrac13\right)=20\implies x+\dfrac13=-5\implies\boxed{x=-\dfrac{16}3}$
