Question

8) Sarah purchased a new laptop. The laptop states that it weighs 0.25 oz per cubic inch and it measures 2” thick'(tall), 10” width and a diagonal of 15.62” .
a. How many pounds does Sarah’s laptop weigh?'
b. Sarah also needs to purchase a protective sleeve for her laptop, how big must the sleeve be?

Answer 1

you should be able to figure this out! The density of the laptop is 0.25 oz/cubic inch. If the volume is 2*10*15.62 cubic inches. you multiply that by density to find the weight. (Strange that the question poses that the laptop has a density. Laptops have an uneven weight distribution per cubic inch...plus a laptop opens up so I wonder if this is just the motherboard and keypad of the laptop or it is the laptop folded down (screen and keypad).



..............which brings me to part b: why do you need to know how big of sleeve is. is it a protective sleeve for the screen, the entire laptop. Then wouldn't it just be the volume of the laptop (folded down), but 25% bigger.

Answer 2

a million) All you'll be able to desire to do for this question is locate the gap between the two given factors. the 1st turtle would be 2 gadgets alongside this line from the 1st factor and the 2nd turtle would be 3 gadgets alongside this line from the 2nd factor. to locate the shortest distance that the turtles might desire to be from one yet another you basically might desire to subtract 5 from the gap you calculated between the factors. So first use the gap formulation then do the subtraction. 2) surely 3) No 5 a million/3 x 2 a million/4 = sixteen/3 x 9/4 = 4/a million x 3/a million = 12 4) desire it is what you advise: 7 a million/2 x 5 a million/3 + 5 a million/4 x 5 a million/3 = 15/2 x sixteen/3 + 21/4 x sixteen/3 = 5/a million x 8/a million + 7/a million x 4/a million = 40 + 28 = sixty 8 5) a million 3/8 x a million a million/3 = 11/8 x 4/3 = 11/2 x a million/3 = 11/6 = a million 5/6 So the mother is a million and 5/6 situations as tall as her son

Answer 3

what motivation do i have to go and solve your math hw?

solve it yourself. you have trouble with something like that, then you need to work on you math, and asking for questions here won't help. Almost every teacher in the world likes it when you attempt to solve the problem and get it wrong than to have an answer with no way to explain how you got it.



this is the answer (but it may not be correct because why do I have to give you the right answer):

78.1 oz.



I don't want to solve problem 2.
