y=x+4

2x=x+4

2x+−x=x+4+−x(Add -x to both sides)

x=4

What is the approximate rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m?

HELP PLEASE I WILL MARK BRAINLIEST!!♥️

Answers

Answer:

-21 tickets per hour

Step-by-step explanation:

I think it's right

Answer:

Therefore, the correct answer is option C. 21 tickets per hour.

Step-by-step explanation:

Given: the opening day ticket sales for the park is given by the function[tex]T(h)=\frac{386+110h}{h}[/tex] where [tex]T(h)[/tex] represents the number of tickets sold [tex]h[/tex] hours after opening at 7:00 a.m.

To find: the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m.

For 10 a.m., [tex]h=3[/tex]

So the number of tickets sold upto 10 a.m. are,

[tex]T(3)=\frac{386+110 (3)}{3}[/tex]

[tex]T(3)=238.67[/tex]

Similarly, for 1 p.m., [tex]h=6[/tex] hours

So, the number of tickets sold in 6 hours are,

[tex]T(6)=\frac{386+110(6)}{6}[/tex]

[tex]T(6)=174.33[/tex]

Now, the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m is,

[tex]\frac{T(6)-T(3)}{6-3}[/tex]

[tex]=\frac{174.33-238.67}{3}[/tex]

[tex]=-21.445[/tex]

which is approximately [tex]-21[/tex] tickets per hour.

Hence, the rate of change in the number of tickets sold between 10:00 a.m and 1:00 p.m is -21 tickets per hour.

The correct answer is option C.

A block of marble is in the shape of a rectangular prism. The block is 2 feet long. 3 feet wide, and 90 inches high. What is the volume of the block? The volume of the block is cubic feet​

Answers

Answer:

Volume of a rectangular prism can be found with the equation

v = length × width × height

They are trying to trip you up a little bit here because they give 2 measurements in feet then the last in inches. So for your prism...

18 inches = 1.5 ft

v = l×w×h

v = 3×2×1.5

v = 9 ft^3

Volume=length*width*height, so first you would have to change the units of the inches to feet, which would be 90/12=7.5, so now you can fit that into the equation, 2*3*7.5=45 ft cubed!

when he flips the coin, there are 2 outcomes = {front, back}

When he rolls a die, there are 6 outcomes = {1, 2, 3, 4, 5, 6)

For every outcomes of coin there are 6 outcomes of a die.

can someone help me on this?

Answers

Answer:

⅜ or ⅗

Step-by-step explanation:

I say ⅜ because of how many variables you can take into account 3 different colors, and a 2 sided coin, lastly 3 different numbers. So in total that is 8 possible variables and the 3 being blue, heads, and landing on 1.

Now I say ⅗ because of this perspective on the variables. You have the 3 colors, and your two sided coin but thing here is that the 1 is basically another color so the question is technically asking for the probability of spinning blue, landing on heads and landing on red in a sense.
