5 and 1/5 of cake because the difference of 8 and 1/10 and 2 and 9/10 is 5 and 2/10 or 5 and 1/5

1. Dalia makes a cranberry apple punch that contains 20%, percent real juice by mixing x gallons of a cranberry drink with y gal

Vladimir79 [104]

Answer:

The required equations which represents the relationship between x and y is $0.2(x+y)=0.4x+0.1y$ .

Step-by-step explanation:

Consider the provided information.

Dalia makes a cranberry apple punch that contains 20%, percent real juice by mixing x gallons of a cranberry drink with y gallons of an apple drink.

This can be written as: $\frac{20}{100}(x+y)$

The cranberry drink contains 40 percent real juice and the apple drink contains 10 percent real juice.

This can be written as: $\frac{40}{100}x+\frac{10}{100}y$

Now both the equation are equal.

$\frac{20}{100}(x+y)=\frac{40}{100}x+\frac{10}{100}y$

$0.2(x+y)=0.4x+0.1y$

Hence, the required equations which represents the relationship between x and y is $0.2(x+y)=0.4x+0.1y$ .

Help with this i dont understand

velikii [3]

Answer:

a) 3/4

b) 3/4

c) 3/4

d) all are 3/4

Step-by-step explanation:

The slope of a line is defined as the change in y divided by the change in x. This is often referred to as "rise over run":

slope = Δy/Δx = "rise"/"run"

The triangles are drawn against the line so that you can use them to identify values of "rise" (vertical change) and "run" (horizontal change) between two points on the line.

The slope of the segment AC is found by dividing the "rise" (BC = 3) by the "run"(AB = 4)

slope of AC = BC/AB = 3/4

The slope of FH is similarly computed. Here, it is made a little more difficult, because you must estimate the value of GH.

slope of FH = GH/FG = 1.5/2 = 0.75 = 3/4

The slope of CE is ...

slope of CE = DE/CD = 6/8 = 3/4

The slopes in a), b), c) are all 3/4.

You can reasonably draw the conclusion that the slope of a line is the same everywhere. A line has constant slope.

Our model is

$\hat{y} = 2.17 x + -114.05$

When x=82 degrees F,

$\hat{y} = 2.17 (82) + -114.05 = 63.89$

We round up to

Answer: 64 bags

Not sure why it says y^=34 in the question; I'm ignoring that.

The residual is the difference between the actual y and the predicted y,

$e = y - \hat{y} = 66 - 64 = 2$
