1/3y+1/4=5/12 Can someone give me easy steps for this

1 answer:

4 0

1) Set the equation equal to 0.
In order to do that, subtract 5/12 on both sides of the equation. Now you have 1/3y-1/6=0. If you need just an equation, there it is. If you need to go farther to find y, continue to step two.
2) Now get the variable by itself.
Add 1/6 to both sides. Now you have 1/3y=1/6.
3) Now divide 1/3y by both sides- but wait- it's a fraction.
So you have to multiply by the reciprocal which means multiply by 3 to both sides in this case.

So y=1/2.
Hope that's right and that it helped!

A dartboard consists of a circle inscribed in a square. The area of the circle is 16π square centimeters. The area of the square

lapo4ka [179]

The solution would be like this for this specific problem:

Area of Circle = 16(π)

= 16 * 3.14

= 50.24

Area of Square = 64

= 64 – 50.24

= 13.76

Area of Square but not on the circular board = 13.76 / 64

= 0.215

Percentage value = 0.215 * 100%

= 21.5%

So, <span>to the nearest percent, the probability that the dart lands inside the square but not on the circular dartboard is 21.5%.</span>

Bob rolls a fair six-sided die each morning. If Bob rolls a composite number, he eats sweetened cereal. If he rolls a prime numb

hammer [34]

Bob eats a 171 days sweetened cereal and 194 days he eat unsweetened cereal.

According to the statement

we have given that the Bob rolls a composite number, he eats sweetened cereal. If he rolls a prime number, he eats unsweetened cereal.

and we have to find that the expected value of the difference between the number of days.

So, the total number of days in a year is 365 days.

Chance to get a prime number on a die = 3/6

Chance to get a prime number on a die = 1/2.

and chances to get a composite number = 2/6

chances to get a composite number = 1/3

and chances to get a 1 on a die = 1/6.

Then the expected value =

so, expected value = 365(1/6) + 365(1/3) + 365(1/2)

then after calculating

Expected value = 1+2+1

then the value become is 4

and by this way he eat 171 days sweet cereal and other days he eat unsweetened.

So, Bob eats a 171 days sweetened cereal and 194 days he eat unsweetened cereal.

(35 points)is x=1 and y=1 perpendicular or paralell to eachother or neither

Artyom0805 [142]

Perpendicular because y=1 goes across and x=1 goes vertical forming a right angle

This equation was solved incorrectly.

Charra [1.4K]

What was i correct was the 2nd step since when multiplying -2x-6 it would be a positive 12 not a negative :)
