Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

Answer:

8 cm cubed

Step-by-step explanation:

Because that the cubes are well, cubes, all the sides are the same. If 1 side= 1, then the other ones are too. Once you look at the prism, you will notice that there are 8 cubes in total. Let's find the volume of 1 cube first:

The formula is:

w*h*l = v

1*1*1=1

The volume for 1 cube is 1 cm cubed.

1*8=8

The volume for the prism is 8 cm cubed.

2. Let the polynomial be [tex]ax^{p} +bx^{q} +cx^{r}+....+nx+m[/tex]. If x=1, then the whole thing can be seen as a+b+c+...+n+m, which is exactly the sum of the coefficients of f, which is 32.

Using the probability concept, it is found that:

a) 41.67% of the total students surveyed like both Volleyball and Tennis.

b) There is a 0.1667 = 16.67% probability that a student who does like

Volleyball does not like Tennis.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Item a:

There is a total of 70 + 50 = 120 students, and x + 20 = 70 -> x = 50 like both sports, hence:

p = 50/120 = 0.4167.

41.67% of the total students surveyed like both Volleyball and Tennis.

Item b:

60 students like voleyball, and of those, 10 do not like tennis, hence:

p = 10/60 = 0.1667 = 16.67%.

There is a 0.1667 = 16.67% probability that a student who does like

Volleyball does not like Tennis.

Answer:  30 lbs, 13 oz

This converts to 493 ounces

===============================================================

Explanation:

Pumpkin A weighs 7 lb, 12 oz. Let's convert that to ounces only

1 lb = 16 oz

7 lbs = 112 oz (multiply both sides by 7)

7 lbs, 12 oz = 112 oz + 12 oz .... add 12 oz to both sides

7 lbs, 12 oz = 124 oz

Pumpkin A's weight of 7 lbs, 12 oz is the same as 124 oz

-----------

Do something similar for pumpkin B

1 lb = 16 oz

10 lbs = 160 oz

10 lbs, 4 oz = 160 oz + 4 oz

10 lbs, 4 oz = 164 oz

Pumpkin B weighs 164 oz

-----------

Let's convert the "2 lbs, 9 oz" to ounces only

1 lb = 16 oz

2 lbs = 32 oz

2 lbs, 9 oz = 32 oz + 9 oz

2 lbs, 9 oz = 41 oz

So pumpkin C is 41 ounces heavier compared to pumpkin B

The weight of pumpkin C is 164+41 = 205 ounces

----------

We have these three weights in ounces only

Adding those three ounces only weights leads to

124+164+205 = 493 ounces

The total weight of all three pumpkins is 493 ounces

Now let's convert back to the unit "pounds, ounces"

Divide that result over 16 since there are 16 ounces per pound

493/16 = 30.8125

Ignore the decimal portion. The 30 is the quotient which means 493-30*16 = 13 is the remainder.

In other words,

493/16 = 30 remainder 13

which leads to

493 ounces = 30 pounds, 13 ounces

--------------

As a check,

1 lb = 16 oz

30 lbs = 480 oz

30 lbs, 13 oz = 480 oz + 13 oz

30 lbs, 13 oz = 493 oz

The answer is confirmed.

Answer:

y = 0.45x + 2.85

Step-by-step explanation:

to solve we can first subtract the initial cost by taking the price at 0 miles and subtracting it from one of the higher numbers, we will go with $5.10 at 5 miles for this example

5.10 - 2.85 = 2.25

now we have the price for just the 5 miles separated from the initial cost, but we still need to figure out what each single mile is, so now we just divide by 5, one for each mile

2.25 / 5 = 0.45

so $0.45 is the cost to ride for one mile, and the initial cost is 2.85, now all we have to do is implement those numbers into a formula, since 0.45 is for each mile, it is multiplied by the miles, or x, so that will be put together below

0.45x

then we have the value to add to that, 2.85

0.45x + 2.85

and that is = to y, the cost to ride in a San Francisco taxi

The cost of a taxi in San Francisco is higher compared to New York and the equation of line is y = 0.75x + 2.85

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

y = 0.40x + 2.50   be equation (1)

where y represents the cost of the taxi in New York for x miles driven

Let the first point be P ( 0 , 2.85 )

Let the second point be Q ( 5 , 5.10 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 5.10 - 2.85 ) / ( 5 - 2 )

Slope m = 0.75

And , the equation of line for the cost of the taxi in San Francisco for x miles driven is given by

y - ( 2.85 ) = ( 0.75 ) ( x - 0 )

Adding 2.85 on both sides , we get

y = 0.75x + 2.85   be equation (2)

So , when x = 1 mile

y = $ 3.60

And , when x = 1 in equation (1) , we get

y = $ 2.90

Therefore , the cost of a taxi in San Francisco is higher compared to New York

Hence , the equation of line is y = 0.75x + 2.85 for the cost of taxi in San Francisco
