3.2 x 5 = 16

1.5 x 2 = 3

16 + 3 = 19

19 x 6 = 114
Rachel will run 114 miles in 6 weeks.

Rachel will have run 114 miles in six weeks.

Further Explanation

<u>Given:</u>

Rachel runs 3.2 miles each weekday ⇒ 5 days a week

1.5 miles each day of weekend ⇒ 2 days

<u>Question:</u>

How many miles will she run in six weeks?

<u>Step-by-step explanation</u>

First step, we will calculate how many miles Rachel runs in a week, the equation will be:

$\boxed {= (5 \times3.2) + (1.5 \times2) }\\\boxed {= 16 + 3\ }\\\boxed {= 19\ }$

so rachel runs 19 miles a week

For six weeks, Rachel will have run:

$\boxed {=19 \times 6\ }\\\boxed {=114 miles\ }$

<u>In six weeks, Rachel will have run 114 miles</u>

You have just timed a person doing a hair cut for the first time. It took 50 minutes. What unit improvement factor learning curv

Sladkaya [172]

Answer: C. 70 percent

Step-by-step explanation:

Given, Time for the first unit = 50 minutes

Time for the second unit = 35 minutes

The unit improvement factor learning curve = (The time for the second unit) ÷ (time for the first unit) x 100.

So, The unit improvement factor learning curve = 35÷ 50 × 100 = 70 percent.

Hence, the correct option is "C. 70 percent".

Solve the equation without the use of a calculator. please Help!!! Thank you!!!<br> 12x^3-30x=5-2x^2

nata0808 [166]

So, since we have a cubic equation with 4 terms, the first thing we should try is factoring by grouping, so:

$12x^3+2x^2-30x+5 =0 \implies \\ 2x^2(6x+1)-5(6x+1)=0 \implies \\ (2x^2-5)(6x+1) = 0$

Now that we've factored our equation, we can use ZPP and break it up:

$2x^2-5 = 0 \implies \\ 2x^2=5 \implies\\ x^2=\frac{5}{2} \implies\\ x=\pm\frac{\sqrt{5}}{\sqrt{2}}=\pm\frac{\sqrt{10}}{2} \\ \\ 6x+1 =0 \implies \\ 6x=-1 \implies\\ x=\frac{-1}{6}$

So, our solutions are:

$x\in \{\frac{\sqrt{10}}{2},-\frac{\sqrt{10}}{2},-\frac{1}{6}\}$
