Ok; Since we know that in 45 min, she can walk 3 miles, we can divide it to see how many minutes it takes for her to walk 1 mile. 45 divided by 3 is 15. Which means it takes her 15 minutes to walk 1 mile. If we look back at the beginning, it says she takes 15 minutes. Now that we know that it takes her 15 minutes to walk 1 mile, the answer is that it takes her 1 mile to walk to the library.

Really simple.

You know that speed is v = d/t
so 3/45 = 1/15  or 1 mile per 15 mins

So since she took 15 mins i know the library is 1 mile

Answer:

Quadratic Equation:

3x^2=2x +5

\text{Standard Form: } 3x^2-2x-5=0

From the standard form of a Quadratic Function, we get:

a=3,\:b=-2,\:c=-5

Discriminant:

\Delta=\left(-2\right)^2-4\cdot \:3\left(-5\right)

\Delta=\left(-2\right)^2+4\cdot \:3\cdot \:5

\Delta=64

From the discriminant, we conclude that the equation will have two real solutions.

State that:

b^2-4ac

b^2-4ac =0:\text{The equation has 1 real solution}

b^2-4ac >0:\text{The equation has 2 real solutions}

By the way, solving the equation given:

$x=\frac{2\pm\sqrt{64}}{2\cdot \:3}$

$x=\frac{2\pm\sqrt{64}}{6}$

$x=\frac{2\pm8}{6}$

$x_{1} =\frac{10}{6}=\frac{5}{3}  $

$x_{2}=\frac{-6}{6} =-1$

Answer:

2,598,960

Step-by-step explanation:

It is a combination because order doesn't matter. You wouldn't want to call A-K-Q-J-10 of hearts a different combination than 10-J-Q-K-A.

Help!!! Carla earns $6.25 per hour working at a store. When she gets her paycheck she repays her brother $40. She has at least $
lora16 [44]
What i did was add 40 to 120 to get 160. then i devided 160 by the 6.25 she got per hour and i got 25.6 and rounded to 26 which would end up being the least amount of hours she could’ve worked. so 26 is the answer i’m pretty sure
