Answer: The place value of zero in any number is always zero. Zero may hold any place in a number, but its value will remain to be zero. In numbers having zeros such as 105, 350, 42017, 90218, the place value of 0 in each number is 0.

- Well , You can solve this question using two ways. I'm gonna use the both ways to make you clear and the one which you can easily understand , pick up that way and start solving another question as similar as this one.
![\large{ \tt{❃ \: FIRST \: METHOD }} :](https://tex.z-dn.net/?f=%20%5Clarge%7B%20%5Ctt%7B%E2%9D%83%20%5C%3A%20FIRST%20%5C%3A%20METHOD%20%7D%7D%20%3A%20)
This method is related to the unitary method. Let's start :
- We're provided - Amount Kelly earns per hour for gardening = $ 12.75 and we're asked to find out the amount she earn if she worked 45.75 hours this month.
- We know , Kelly probably earns more money if she worked 45.75 hours comparison to if she worked 1 hour. So You just multiply 45.75 & 12.75 , you would get $ 583.3125 and that's your final answer.
![\large{ \tt{❃ \: SECOND \: METHOD}} :](https://tex.z-dn.net/?f=%20%5Clarge%7B%20%5Ctt%7B%E2%9D%83%20%5C%3A%20SECOND%20%5C%3A%20METHOD%7D%7D%20%3A%20)
This method is related to the proportion. If you haven't learned about it yet , use the above way to solve the similar type of questions. Let's start :
- Let Kelly earns X dollars if she worked 45.75 hours this month. [ Now , See the attached picture ]
- Here , we can see the time is increased which implies that money will surely be increased. Such type of proportion is called direct proportion.
- Here , the ratio of time ( in hours ) = 1 : 45.75 and the ratio of amount ( in dollars ) = 12.75 : x . Now , Set up an equation and solve for x :
![\large{ \tt{ ❁ \: \frac{1}{45.75} = \frac{12.75}{x}}}](https://tex.z-dn.net/?f=%20%5Clarge%7B%20%5Ctt%7B%20%E2%9D%81%20%5C%3A%20%5Cfrac%7B1%7D%7B45.75%7D%20%20%3D%20%20%5Cfrac%7B12.75%7D%7Bx%7D%7D%7D%20)
![\large{ \tt{↦ \: 1 \times x = 45.75 \times 12.75}}](https://tex.z-dn.net/?f=%20%5Clarge%7B%20%5Ctt%7B%E2%86%A6%20%5C%3A%201%20%5Ctimes%20x%20%3D%2045.75%20%5Ctimes%2012.75%7D%7D)
![\large{ \tt{↦x = \$ \: 583.3125}}](https://tex.z-dn.net/?f=%20%5Clarge%7B%20%5Ctt%7B%E2%86%A6x%20%3D%20%20%20%5C%24%20%20%5C%3A%20583.3125%7D%7D)
- Hence , She earned $ 583.3125 .

Answer:
Leon (2.12), Jacon (2.40), Ashley (2.50), Mika (2.57)
Step-by-step explanation:
Putting a mix of rational and irrational numbers into numerical order can be done by using approximations to them of sufficient precision to be able to tell them apart.
Here, we can make the following approximations:
√17 -2 ≈ 2.12
1 +π/2 ≈ 2.57
Of course, the decimal value of 12/5 is 2.40, so the numbers will be arranged in order if Mika moves to the right end:
Leon (2.12), Jacon (2.40), Ashley (2.50), Mika (2.57)

Answer:
slope: 1/2
Step-by-step explanation:
Finding the slope:
(8,4) (4,2)
(x1, y1) (x2, y2)
Subtract the x values and subtract the y values. (x1 - x-2) and (y1 - y2)
8 - 4 = 4
4 - 2 = 2
The slope is written as rise over run or y over x.
So, 2/4
Simplify: 1/2
