AnnyKZ [126]3 years ago
4 0

Answer:

$0.25

Step-by-step explanation:

Site A pays ...

... $0.65 × 5 = $3.25

Site B pays ...

... y = 0.60·5 = 3.00 . . . dollars

Site A pays more by ...

... $3.25 - 3.00 = $0.25

_____

You can also look at the difference in unit rates. Site A pays $0.65 per photo, while site B pays $0.60 per photo, a difference of $0.65 - 0.60 = $0.05 per photo. Then 5 photos will be worth $0.05 × 5 = $0.25 more at Site A.

How much material is required to make a pipe that is 300 cm long whose outer diameter is 8 cm with an inner diameter of 5 cm? Sh
worty [1.4K]

Answer:

Step-by-step explanation:

If you had a solid cylinder, in order to find the amount of material that makes up that solid cylinder, you would find the volume using the radius of 4 (half of the diameter 8).  BUT we want to know the volume of the solid with the radius of 4 minus the solid that has a radius of 2.5 (half of the diameter 5).

V_o-V_i  That's volume outer - volume inner.  To find the outer volume:

V=\pi r^2h so

V_o=\pi (4^2)(300) and

V_o=4800\pi  and do the same for the inner volume:

V_i=\pi (2.5^2)(300) and

V_i=1875\pi

Subtract the inner from the outer:

4800\pi-1875\pi=2925\pi cm^3

If you need your answer in decimal form, then the volume is

9189.16 cm³

What is the solution to this system if equations
Inessa05 [86]

solution is (x, y ) → (- 1, 4 )

y + 2x = 2 → (1)

y + 4x = 0 → (2)

subtract equation (1) from (2) to eliminate term in y

(y - y ) + (4x - 2x ) = (0 - 2 )

2x = - 2 ( divide both sides by 2 )

x = - 1

substitute x = - 1 in either (1) or (2) and solve for y

(1) → y - 2 = 2 ( add 2 to both sides )

y = 4

solution is (x, y ) → (- 1, 4 )

Which expression represents the statement below:
ikadub [295]

Answer:

2x+16

Step-by-step explanation:

16 is your b( so to speak) in this expression so ? +16 (since 16 is a positive you add it) then it says double a number X so 2 times x equals 2x 2x+16 is your expression

Hhhhhhhhhheeeeeeeeeeeeeeeeeeeeeeeeelllllllllllllllpppppppppppppppppppppp
loris [4]
Remember that both the denominator and the square root function cannot have values less than 0.  So to figure what values can go into each we need to do a little math.  Set both the denominator and the under the radical equal to 0
x + 2 = 0            x - 3 = 0
x = -2                 x = 3

Since they must be those numbers or bigger 3 is the larger of the 2 the final answer is
x >= 3  Type in greater than into the box

Find the slope of a line that passes through the given points. Write your answer below.
12345 [234]
Just use the formula:
slope(m) = \frac{y_2-y_1}{x_2-x_1}

Then, plug in numbers:
m = \frac{1-4}{-2-3} = \frac{-3}{-5} = \frac{3}{5}

And that would be your answer: 3/5 is the slope.
