Answer:

B. 30

Step-by-step explanation:

What we know: Beyunka has 6 baseballs that she keeps. That is 1/5 of the total that comes in one case.

What we need to know: How many baseballs are in one case?

What we need to do: Divide 6 by 1/5 (or multiply by 5).

6 / (1/5)

Dividing a fraction is the same thing as multiplying by its inverse.

6 * 5

Multiply 6 by 5 to get 30.

30

There are 30 baseballs in one case, so B is our answer.

Answer:

B. 1/2

Step-by-step explanation:

That is because there are 10 total jellybeans

we need to get purple and orange.

There are 2 purple and 3 orange = 5

5/10 jellybeans are what we need

5/10 simplified is 1/2

Answer:

The price of the soda.

Step-by-step explanation:

The dependent variable is the variable defined to be dependent on another object, typically the independent variable. That means the variable that varies based off of another value is the dependent variable. In this situation, as the number of sodas bought increases, the total price increases. The price varies off of the number of sodas because the increase in sodas causes it to increase. Thus, the price is the dependent variable.

The dependent variable would be the total cost of the sodas.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

Each soda costs $4.50 at the baseball game.

Here, The cost of the sodas is dependent on the number of sodas purchased, which is the independent variable.

Thus, The dependent variable would be the total cost of the sodas.

Answer:

y=2x-50

Step-by-step explanation:

[tex]m=\frac{y^2-y^1}{x^2-x^1} = \frac{112-106}{81-78} =\frac{6}{3} =2[/tex]

slope-intercept formula(substitute 81 for x, 112 for y, and 2 for m:

y=mx+b

112=2(81)+b

112=162+b

Then subtract 162 from both sides, and b=-50

Plug in all numbers into original equation

y=mx+b  m=2 b= -50

So u get y=2x-50

Answer:

a. 72

Step-by-step explanation:

Sorry about your allergies :(

Surface area = top & bottom, which are the same, and all 4 sides' areas added together:

top and bottom: each is 3 x 2 = 6 square cm, times 2 = 12 square cm.

two sides are 6 x 3 cm = 18, times 2 = 36 square cm

other two sides are 6 x 2 cm = 12, times 2 sides = 24 square cm

Add them all up: 12 + 36 + 24 = 72 square cm

Answer:

its A

Answer:

Volume is length times width times height. So, you would need to do 9 times 3 (27) times 10 (270). Then, you would divide by 10, because it is scaled down by 1/10, leaving you with 27

X = 74°

Step-by-step explanation:

90 + 30 = 120 (S + T = 120 )

180 - 120 = 60 (triangles total - S and T's Total = U )

120 - 46 = 74 (The angle TUX is 120 so the answer is 74)

Answer:

The representation of Brian's situation in slope intercept form is:

                              y= 15x +70

Step-by-step explanation:

Let x be the number of weeks Brian started his collection.

y be the number of cards Brian has at present.

                         y= 45+25+ 15 x

                   or, y= 15 x +70

which is in the form of,

                              y= mx +c                (slope intercept form)

where,

m= slope

x= x- intercept

c= constant.
