A painter mixes 6 parts red paint and 8 parts yellow to make dark orange paint. Which equation can the painter use to calculate

the amount of red paint, R, that is needed to mix with a given amount with yellow paint, Y? A. R= 6/8 = Y, B. R=6/8- Y, C. R=3/4y, D. R= 4/3Y.

Red : Yellow
   6   :  8
 (÷6)  (÷6)
   1   : 8/6 
   1   : 4/3

therefore, R = 4/3Y

Answer: R = 4/3Y

What is the slope between (-4,4) and (-6,6)
nalin [4]

\textsf{Let's calculate the slope of the line passing thought the points (-4, 4) and (-6, 6) } \\ \textsf{using the following formula: }\mathsf{m = \frac{\Delta y}{\Delta x}} \textsf{ where m is the slope of the line.}\textsf{So:}

\mathsf{m = \dfrac{\Delta y}{\Delta x} = \dfrac{4 - 6}{-4 - (-6)} = \dfrac{-2}{2} = -1}

\textsf{Hence the slope is -1.}

Does anyone know if 2/8 is equivalent to 16/64???
Papessa [141]

Answer:

Step-by-step explanation:

How is 16 related to 2?  We multiply 2 by 8, obtaining 16.

How is 8 related to 64?  We multiply 8 by 8, obtaining 64.

So 2/8 is equivalent to 16/16.

Answer:

y =3x - 5

Step-by-step explanation:

Well one of the way to do this question is the formula given below your question, but for me, i rather do it this way

OK they gave u y=3x - 12

And they say another line is parallel, once u see the word parallel means they have the same angle, same slope, same gradient ( sorry if I give u the wrong terms, since I learn mine in Malay)

So first u got to understand the slope-intercept form

y = mx + c

y is your y coordinate

x is your x coordinate

m is your gradient ( as in how much the line slants)

c is the y - intercept, as in, if u draw a graph, the y-coordinate where your line touches the y-axis (the vertical line)

So since the say the both lines are parallel, so both of their "m" is the same that is 3. Why? Cuz just compare

y = mx + c

y = 3x - 12

Therefore the m is 3

Therefore u alredy got your first value, so put it in your slope intercept form

y = mx + c

y = 3x + c

Now how to find c? Very easy, just put in the value of y and x from the coordinate ( that the line youre finding is on) they gave u, just put the value in

They gave u

(1, - 2)

So when x = 1, y = - 2

Therefore put it in

y = 3x + c

-2 = 3 (1) + c

c = - 5

Since now u have your m and c value, your slope intercept form is done, just put it in

y = mx + c

y = 3x + (-5)

y = 3x -5

Results from a survey conducted in a certain grocery store showed that 3 out of 5 people preferred crispy-flakes cereal to crunc
BabaBlast [244]

The number of people who how many most likely purchased crunchy-flakes cereal is 1000 customers.

<h3>How many most likely purchased crunchy-flakes cereal?</h3>

Ratio expresses the relationship between two or more numbers. It shows the number of times that one value is contained within other value(s).

The first step is to determine the ratio of people who preferred crunchy-flakes cereal:

Ratio of people who preferred crunchy-flakes cereal : 5 - 3 = 2

Now, multiply the ratio of those who prefer crunchy-flakes cereal by the total number of customers: (2/5) x 2500 = 1000  customers.
