Answer:
186
Step-by-step explanation:
PEMDAS
First do 46 x 8 = 368 then divide that by 2, which would be, 184. Then add 2 to 184 and you get 186. :)
Answer:
The number of ways are 40320.
Step-by-step explanation:
Consider the provided information.
Ms. Smith keeps eight different cookbooks on a shelf in one of her kitchen cabinets.
We need to determine the number of different ways to put eight cookbooks on the shelf.
We need to select 8 cookbooks taking 8 at a time.
So use the permutation formula: 
Substitute n=8 and simplify.
Hence, the number of ways are 40320.
Answer:
5120oz/12=426.667 ounces.
Step-by-step explanation:
We know 1 pound = 16 oz. If we want to find out how many ounces are in 320 lbs, we must multiply 16 by 320 = 5120 ounces. Now we must divide by 12 to see how much she ate per month. 5120 divided by 12 is 426.667 or 426 and 2/3 ounces per month.
Alternatively, we can set up a proportion 1 lb / 16 ounces = 320 lb / x ounces. We cross multiply 1 times x = 320 times 15. On the left hand side we just have x and on the right hand side we get 5120. Hence, x=5120 ounces per year. To find how many she ate per month we must divide by 12 since there are 12 months in a year. So it comes out to 426 and 2/3 ounces per month.
Here are the equations: (1lb)(320lb)=(16oz)(320oz) implies 320lb=5120oz. Then divide 5120oz 12 to get how much she ate per month: 5120oz/12=426.667 ounces.
Answer:
what type of question is this???
Answer:
If x=8 then the equation is equal to 33
If 1/2(x)^2-1/4x=3=8 then x=-2.98 and x=3.35
Step-by-step explanation:
Given:
1/2x^2-1/4x+3
Two solutions possible:
If x=8 then 1/2(8)^2-1/4(8)+3=32-2=3=33
If 1/2(x)^2-1/4x+3=8 then .5x^2-.25x-5=0
factoring:
(.707x+2.11)(.707x-2.37)=0
.707x=-2.11 and .707x=2.37
x=-2.98 and x=3.35 rounded to 2 places
