Answer:

D

Step-by-step explanation:

We can use the "vertical line test" to determine whether a given graph represents a function or not.  

If your vertical line intersects the graph in more than one place, the graph does NOT represent a function.  Thus, D does not represent a function, as a line drawn vertically thru this graph intersects the graph multiple times.

Graph A:  Note that if you draw a vertical line thru x = -2, your line will intersect the BLACK dot (-1 3/4, 0) and the EMPTY circle (-1 3/4, 3 1/4).  This is OK; this graph represents a function.

Yasmine bought 6 gallons of apple juice. After filling up 4 bottles of the same size with apple juice, she had 0.3 gallon of apple juice left.

Answers

1.425 gallons/bottle.

Further explanation

Given:

  • Yasmine bought 6 gallons of apple juice.
  • After filling up 4 bottles of the same juice, she had 0.3 gallons of apple juice left.

Question:

What is the amount of apple juice in each container (or bottle)?

The Process:

Let the amount of apple juice in each bottle as X.

The two steps for obtaining X are as follows:

Step-1: the total amount of apple juice is the initial gallon amount subtracted by the remaining gallon amount.

\boxed{ \ 6 \ gallons - 0.3 \ gallons = 5.7 \ gallons \ }

Step-2: the total amount of apple juice divided by the number of bottles is the amount of apple juice in each bottle.

\boxed{ \ X = 5.7 \ gallons / 4 \ bottles = \boxed{ \ 1.425 \ gallons/bottle \ } \ }

Let's also consider the following quick steps.

Quick steps:

\boxed{ \ X = ((6 - 0.3) \ gallons)/(4 \ bottles) = \boxed{ \ 1.425 \ gallons/bottle \ } \ }

Therefore, the amount of apple juice in each container (or bottle) is 1.425 gallons.

The size of each bottle that is filled by apple juice is \boxed{\bf 1.425}.

Further explanation:

Given:

Yasmine bought 6 gallons of apple juice.

She filled up 4 bottles of same size.

She had 0.3 gallon of apple juice left.

Calculation:

Consider the size of each bottle is x gallons.

Total size of each bottle is 4x gallons.

Total amount of apple juice used in these 4 gallons can be obtained by subtracting total amount of apple juice to remaining apple juice.

\boxed{6-0.3=5.7}

Therefore, total size of the 4 bottles is 5.7\text{ gallon}.

Write the equation for the total size of the bottles.

\boxed{4x=5.7}  

Now find the value of x which gives the size of the bottles.

\begin{aligned}4x&=5.7\nx&=(5.7)/(4)\nx&=1.425\end{aligned}  

Therefore, the size of each bottle that is filled by apple juice is \boxed{\bf 1.425}.

Simple method:

First find the total size of bottle and then divide by 4.

The total size of each bottle can be obtained as follows:

6-0.3=5.7  

The size of each bottle can be obtained as follows:

(5.7)/(4)=1.425  

The size of each bottle that is filled by apple juice is \boxed{\bf 1.425}.

b) Your sister says that the angles ∠DCA and ∠BCA are supplementary angles. Is she correct? Explain your reasoning. (1 point)

Answers

Answer:

She is incorrect.

Step-by-step explanation:

ABCD is a quadrilateral. Angle C measures less than 180 degrees. The sum of the measures of two supplementary angles equals 180 degrees. The sum of the measures of angles DCA and BCA equals the measure of angle C, but angle C measures less than 180 degrees, so the angles are not supplementary.

Answer:

incorrect
