Answer:

$36

Step-by-step explanation:

Answer:

$36.

Step-by-step explanation:

(Hot dog) 2 for 5: Unit price is 5/2 = 2.5

(Soda) 3 for 3 so unit price is 1 for 1.

6 sodas = 6 dollars

12 Hot dogs = 12. x 2.5 = 30 dollars.

Price for both = 30 + 6 = 36.

Answer:

the slope is 8

Step-by-step explanation:

the slope is x not sure if its parallel of perpendicular but is i had to gues id guess parallel

Answer:

the slope is 8

the parallel slope is 8

the perpendicular slope is -1/8

Answer:

x = -1

Step-by-step explanation:

First you multiply by crossover and you get 3(5-x)=18

Then divide the two wings and you'll get 5-x=6

Then you need to separate the x from the numbers

so you move 5 to the right side and you get -x=6-5

Then you calculate it and you get -x=1

and x= -1

hope it helped <3

Answer:

[tex]x=-1[/tex]

Step-by-step explanation:

Given the equation

[tex]\frac{5-x}{9}=\frac{2}{3}[/tex]

[tex]\mathrm{Multiply\:both\:sides\:by\:}9[/tex]

[tex]\frac{9\left(5-x\right)}{9}=\frac{2\cdot \:9}{3}[/tex]

[tex]5-x=6[/tex]

[tex]\mathrm{Subtract\:}5\mathrm{\:from\:both\:sides}[/tex]

[tex]5-x-5=6-5[/tex]

[tex]-x=1[/tex]

[tex]x=-1[/tex]

Answer:

See attachment for what the graph looks like.

Step-by-step explanation:

When you graph these equations, convert 4x+8y=16 into slope-intercept form, which should be y= -1/2x+2.

In this case, 2 is the y-intercept, the part of the line that intercepts with the y-axis, with a negative (goes downward) slope of 1/2.

The line should intersect at (0,2) and have a slope of -1/2.

The x-intercept of the line is at 4 and the y-intercept of the line is at 2. Then the graph is sketched below.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

x/a + y/b = 1

Where 'a' is the x-intercept of the line and 'b' is the y-intercept of the line.

The equation of the line is given below.

4x + 8y = 16

Convert the general form of the line into an intercept form. Then we have

4x + 8y = 16

x/4 + y/2 = 1

The x-intercept of the line is at 4 and the y-intercept of the line is at 2. Then the graph is sketched below.

According the the graph, we see that our x-values are spanning forever in both directions. Therefore our domain is:

(-∞, ∞) or -∞ < x < ∞

Answer:

Displacement is 5.8 meters

Step-by-step explanation:

Here, we want to calculate the displacement of the cat

When we talk of displacement, we mean distance traveled in a specified direction

To find the displacement of the cat, we calculate the distance between where the cat is now from where it started off

So to calculate this, we shall have a right angled triangle where the displacement we want to calculate will be the hypotenuse

We proceed to use Pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the squares of the two other sides

Mathematically, we have ;

D^2 = 3^2 + 5^2

D^2 = 9 + 25

D^2 = 34

D = √34

D = 5.8309

To the nearest tenth, the displacement is 5.8 meters

Step-by-step explanation:

The cards were drawn with replacement. Therefore, the probability of drawing a red card will be [tex](3 / 5)[/tex] at every one of the seven draws. The probability of not drawing a red card would be [tex](1 - (3/5)) = (2/5)[/tex].

One way to get three red cards out of the seven draws would be [tex]\verb!red!\; \verb!red!\; \verb!red!\; \verb!green!\; \verb!green!\; \verb!green!\; \verb!green![/tex]. That corresponds to a probability of [tex](3/5)^3\, (2/5)^{7-3}[/tex].

However, there are many other ways to get three red cards during the seven draws. For example:

There are [tex]\displaystyle {\genfrac{(}{)}{0}{0}{7}{3}} = 35[/tex] such ways in total to choose three draws out of seven draws.

These ways are mutually-exclusive. Each of these ways has a probability of [tex](3/5)^3\, (2/5)^{7-3}[/tex]. The probability for getting a red card on exactly three out of the seven draws would be:

[tex]\displaystyle {\genfrac{(}{)}{0}{0}{7}{3}} \, (3/5)^3\, (1 - (3/5))^{7-3} \approx 0.19[/tex].

Answer:

460 miles

Step-by-step explanation:

Since it is a ratio problem, you see that the prius drives 70 miles on 2 gallons of gas which gives you 70:2 or 70/2.

You also set up the other ratio as a fraction with the unknown value as x --> x/13.

now, you cross multiply

70/2=x/13

70*13=910

910/2=460

460 miles

Answer:

455 miles

Step-by-step explanation:

Distance Prius can travel with one gallon of gas:

70/2

= 35 miles

Distance Prius can travel with 13 gallons of gas:

35*13

= 455 miles
