Riley rakes 1/6 of a lawn in 2/3 hour. How many lawns can Riley rake per hour?
Butoxors [25]

Answer:

Riley rakes 1/4 of the lawns per hour.

Step-by-step explanation:

It is given that,

Riley rakes 1/6 of a lawn in 2/3 hour.

We need to find how many lawns can Riley rake per hour.

In 2/3 hour Riley rakes 1/6 of a lawn

In 1 hour Riley rakes \dfrac{1}{6}\times \dfrac{3}{2}=0.25 = 1/4 of a lawn.

Hence, Riley rakes 1/4 of the lawns per hour.

Caroline started the day with 75 tickets at the fair. At the end of the day, the number of tickets she had was 32% less than wha
Alina [70]

Answer: 24

Step-by-step explanation:

75(0.32) = 24

I got this because 75 is what it started as so I put it as the start of the equation. Then I saw the 32% which would be equal to 0.32 so multiplying would get me the answer because it is a decimal which is smaller than one.

Need Help with 44.. picture above
Daniel [21]

Answer:

Ok:

Step-by-step explanation:

I see that you set up 90 miles = 60 mph * t, where you found out that t = 1.5. What what you needed to do was set 180 miles = 45 mph * t. This is because it is 45 mph for the <em>whole</em> trip. Then, you find that t = 4 hours. That that means that he spent 2.5 hours driving back. Then, we can do d=vt and find 90/2.5 as the speed he went home at. Which comes out to be 36 mph.

Given ​ f(x) = x^2 + 14x + 40 ​. Enter the quadratic function in vertex form in the box. f(x)=
finlep [7]
Recall that the vertex form of a quadratic function (or parabolic function) is equal to

f(x) = a(x - h)^{2} + k

Now, given that we have f(x) = x² + 14x + 40, to express f into its vertex form, we must first fill in the expression to form a perfect square.

One concept that we must remember when completing the square is that

(a + b)² = a² + 2ab + b²

So, to complete the square for (x² + 14x + ____), we have 2ab = 14 where a = 1. Thus, b = 14/2 = 7. Hence, the last term of the perfect square must equal to 7² = 49.

So, going back to the function, we have

f(x) = (x^{2} + 14x + 40 + 0)
f(x) = (x^{2} + 14x + 40 + 49 - 49)
f(x) = (x^{2} + 14x + 49) + 40 - 49
f(x) = (x + 7)^{2} - 9

Thus, we have derived the vertex form of the function. 

Answer: f(x) = (x + 7)² - 9
