Answer:

3/12 = 4/12

3/12 = 1/3

being are last boxes to autofill.

Step-by-step explanation:

1/12 +1/4 = 1/12 + 3/12 = 4.12 = 1/3

When adding the rule of fractions is where required make all denominators the same by dividing the one you want to change to- by the subset one you are changing.

12 / 4 = 3

we get 3/12

Then when adding same denominators 1/12 + 3/12 we just add the top values. = 4/12

The last box would be 4/12 but if asked to simplify we would automatically enter 1/3 for simplification.

As 4/12 = 1/3

Help Me With Math Guys REALLY NEED HELP

The question is ambiguous.

A is right if the second hour is in terms of the original amount (16 grams). That is not how it should be done, but there is nothing in the problem restricting us from doing it that way.

B is right the way most people would do the problem. I would say you should accept this as the right answer. The 4.5% is taken away from what was left after the first hour. I would do it that way left to my own devices.

C. The % conversions are not correct. Those conversions are 35% and 45%
C is not even in contention for being right.

D Same problem as C

A man is sixteen years older than his father, if the total age is 57. How old is the son and the father?

Alex Ar [27]

Answer:

The son is 20 and a half years old.

The father is 36 and a half years old.

Step-by-step explanation:

We can solve this easily by turning it into an equation.

Let the mans age be y and the fathers age be x.

y+x=57

x=y+16

We can use the substitution method to solve for the first equation.

y+(y+16)=57

Now we only have one variable to solve for. Add like terms.

2y+16=57

Subtract 16 on both sides.

2y=41

Divide both sides by 2 to isolate y.

y=20.5

Now substitute 20.5 for y to solve for x.

20.5+x=57

Subtract 20.5 from both sides.

x=36.5

<em>The son is 20 and a half years old.</em>

<em>The father is 36 and a half years old.</em>

Hope this helps!

Graph each absolute value function. State the domain, range, and y-intercept.

Inessa05 [86]

Answer:

i. D:All real numbers

ii.R: $y\le-2$

iii. Y-int: $b=-2.5$

Step-by-step explanation:

The given function is

$y=-\frac{1}{2} |x-1|-2$

The domain of this function are the values of x that makes the function defined.

The absolute value function is defined for all real values.

The domain is all real numbers.

ii. The range refers to the values of y for which x is defined.

$y=-\frac{1}{2} |x-1|-2$

The vertex of this function is

$(1,-2)$

The function is reflected in the x-axis.

The vertex is therefore the maximum point on the graph of the function.

The range is therefore;

$y\le-2$

Or

$(-\infty,2]$

iii. To find the y-intercept, we substitute $x=0$ into the funtion.

$y=-\frac{1}{2} |0-1|-2$

$y=-\frac{1}{2} (1)-2$

$y=-2.5$

The y-intercept is $b=-2.5$

The graph is shown in the attachment.
