Answer:

5 hours

Step-by-step explanation:

This is a tricky question. So first you have to pay $10. Then you can pay $6 an hour. If you think about it, if she rented the bike for 5 hours, (6 x 5 = 30) and paid $10 before she rented the bike, the bill would be $40.

Hope this helped!

I need to find the easiest way to learn how to divide fractions and mixed fractions. I also don't get how to simplify. 5 1/2 div
Crazy boy [7]

5 1/2 can be expressed as,

5\text{ }\frac{1}{2}=\frac{5\times2+1}{2}=\frac{10+1}{2}=\frac{11}{2}

If a fraction x/y is divided by a/b another fraction,

\frac{\frac{x}{y}}{\frac{a}{b}}=\frac{x}{y}\times\frac{b}{a}

So, 11/2 divided by 3/6 is

\frac{\frac{11}{2}}{\frac{3}{6}}=\frac{11}{2}\times\frac{6}{3}=\frac{11}{2}\times2=11

Therefore, 5 1/2 divided by 3/6 is 11.

A chemist mixed 5 mL of Solution A with every 3 mL of Solution B to make a new solution
Nana76 [90]

Answer:

5:3

Step-by-step explanation:

Given that the chemist mixed 5 mL of Solution A with every 3 mL of Solution B to make a new solution with a new concentration.

So, the amount of Solution A in the mixture, a = 5 mL

The amount of Solution B in the mixture, b = 3 mL

Therefore, the ratio of Solution A to Solution B in the new solution with the same concentration is a:b=5:3.

Hence, the required ratio for the same concentration is 5:3.

Please note that none of the given options matched.

What is the axis of symmetry for f(x) = 2x2 − 4x + 5?
Romashka-Z-Leto [24]

Answer:

Axis of symmetry is

C) x = 1

Step-by-step explanation:

we are given equation as

2x^2 -4x+5

we can use axis of symmetry formula

Let's assume we are given quadratic equation as

y=ax^2+bx+c

Axis of symmetry is

x=-\frac{b}{2a}

now, we can compare both equations

and we get

a=2,b=-4

now, we can find axis of symmetry

x=-\frac{(-4)}{2\times 2}

x=-\frac{(-4)}{4}

x=1

MAVERICK [17]

Answer:

The total earnings of Carey  in t tours is 12 t - 2 .  

Step-by-step explanation:

For each hour he babysits, Anderson earns $1 more than half of Carey's hourly rate. Anderson earns $6 per hour. Which equation can be used to solve for Carey's hourly rate, c? 18 + ?T = 24 What number should be the coefficient of t?

Anderson earns $1 more than half of Carey's hourly rate.

Anderson hourly rate = $ 6

Let Carey's hourly rate is p. Let the time is t hours.

So, Anderson rate is

6 t = \frac{p t}{2} +1\\\\2\times 6 t = p t + 2 \\\\p t = 12 t - 2
