x=20.25

Answer:

Graph D

Step-by-step explanation:

The slope of the data is 2.5 because 2.5 cups of flour are used for every ounce of butter. Some points on the graph we can use is (0,0) and (10,4).

(0,0): When there are 0 cups of flour, there are 0 ounces of butter.

(10,4): When there are 10 cups of flour, there are 4 ounces of butter.

Slope=m

[tex]m=\frac{Change(y)}{Change(x)}[/tex]

[tex]m=\frac{10-0}{4-0}[/tex]

[tex]m=\frac{10}{4}[/tex]

[tex]m=2.5[/tex]

Graph D is the only graph containing the point (10,4) and (0,0). So, Graoh D is the correct graph.

Answer:

2 To the 6'th power.

Step-by-step explanation:

2x2x2x2x2=32

twice the value of 32 is 64

2x2x2x2x2x2=64

so your answer would be 2 to the sixth power

hope this helps! :)

Answer:

A.

Step-by-step explanation:

I took the unit test on edge

The height of the cone can be written as h = 3V/(π × r²).

A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.

The formula for the volume of cone is given as V = 1/3 × π × r² × h.

It can be written in terms of h by the method of solving a linear equation as follows,

V = 1/3 × π × r² × h

=> 3V = π × r² × h

=>  h = 3V/(π × r²)

Hence, the expression for height from the given formula can be written as h = 3V/(π × r²).

Step-by-step explanation:

you really need help with that ? it is all already given in the problem description. you only need to do the 6 little calculations (anyways adding 6). what is the problem ?

a1 = 7

a2 = a1 + 6 = well ? ... ... ... 13, of course

a3 = a2 + 6 = 13 + 6 = weeeeelllll ?

a4 = a3 + 6 = 13 + 6 + 6 = weeeellll ?

a5 = a4 + 6 = 13 + 6 + 6 + 6 =

a6 = a5 + 6 = 13 + 6 + 6 + 6 + 6 =

I am really not doing your very basic and just "mechanical" work of doing simple calculations in your head or on your calculator.

I help you, when you have a problem understanding the issue, but not when you ask me to do your pure "mechanical" job that every elementary school student can do easily.

to help with the understanding, such a sequence (using this example) can then be described and every element calculated by

a(n) = a(1) + 6*(n-1)

so, for example

a20 = 7 + 6*19 = 121

so, and now that you truly understand the concept, just use your calculator (if you truly cannot do that in your head) and do your job.

Step-by-step explanation:

The maximum number of pounds p is 224

Step-by-step explanation:

Let

p ----> the maximum number of pounds he can pull without going over the weight limit

we know that

121 pound of rock in the wheelbarrow plus p pounds must be at most 345 pounds

In this problem the word "at most" means "less than or equal to"

so

The inequality that represent this situation is

solve for p

subtract 121 both sides

therefore

The maximum number of pounds is 224

Answer:

268.3 cm³

Step-by-step explanation:

Surface area of triangular pyramid = Base Area + ½*(perimeter of base)(height of pyramid)

Base area = 43.3 cm²

Perimeter of base = 10 + 10 + 10 = 30 cm

Height of pyramid = 15 cm

Plug in the values

Surface area = 43.3 + ½(30)(15)

Surface area = 43.3 + 225

= 268.3 cm³
