What is 1 5/12 + 4 1/6 in its simplest form?

Answers

The answer is 5 7/12, here's why:

First convert the mixed numbers into improper fractions to make it simpler to deal with.

1 5/12 = 17/12
 4 1/6  = 25/6

Now make them equivalent.

17/12 can stay the same,
25/6 can become 50/12

Now it's just 17/12 + 50/12
Just add the numerators!
17/12 + 50/12 = 67/12

All we have to do from here is simplify 67/12.
12 goes into 67 5 times, with a remainder of 7.
5 becomes the whole number, and our fraction is the remainder (7) over 12.

So 67/12 = 5 7/12.
This is as simplified as the answer can get.

Hope this helps!

Step-by-step explanation:

Mr. Gonzales has only $42.50 to spend at a clothing store. He wants to buy a shirt that costs $29, including tax, and some bracelets that cost $4.50 each, including tax. Write an equation to determine x, the maximum number of bracelets Mr. Gonzales could buy. Equation _____________________. Solve the equation to determine the number of bracelets Mr. Gonzales could by. Show your work. Answer _____________________ bracelets

Answers

Answer: The equation is $29 + x*$4.50 = $42.50, and the solution is x = 3

Step-by-step explanation:

The data we have is:

Gonzales has $42.50

He wants to buy:

a shirt that costs $29

some bracelets that cost $4.50 each.

The equation that we need to solve is:

Total cost = money that Gonzales has.

The cost is $29 + x*$4.50

where x is the number of bracelets he can buy.

The equation that we need to solve is:

$29 + x*$4.50 = $42.50

to solve it we must isolate x:

x*$4.50 = $42.50 - $29 = $13.50

x = 13.50/4.50 = 3

So we have that Mr. Gonzales can buy a total of 3 bracelets.
y=4.5x+29 put y=0 so you can solve
0=4.5x+29 minus 29 on both sides to cancel it out
-29=4.5x divide by 4.5 on both sides to find x
-6.44444...=x round to nearest whole number which would be 6 bc he can't have 6.44444 bracelets

Adam uses coconut milk for the desert the coconut milk is in the can the can is 12 cm high and diameter of 8 cm the formula V equals three are 2H how much coconut milk is in the can

Answers

The last portion of the problem is not making sense (?)

However, if one assumes that the can is a straight circular cylinder, the volume of the can:

V = (PI)[(D/2)^2](H)

Given H = 12 cm, and D = 8 cm, substituting these values:

V = PI[(8/2)^2](12)

= 603.1857 cm^3
