Ted ate 3 pieces of the pizza. what is the area of the remaining pizza if the diameter of the pizza is 18 inches?


A. 95.4 square inches

B. 381.7 square inches

C. 159.0 square inches

D. 636.2 square inches.

In this case I believe you would add 25 to both sides. The -25 +25 would cancel out and then +25 would be on the right.

Answer:

f(x)= 10,000(2)^x

Step-by-step explanation:

Exponential equations can be modeled by a(r)^x where a is the initial amount, r is the difference, and x is how many units the equation should be squared by.

A function that describes the bacteria population after d days would be,[tex]\bold{f(d) = 10000\times(1+0.15)^d}[/tex]

An exponential growth function is a function that grows at a constant percent growth rate.

f(t) = a×(1 + r)^(t)

where f(t) = exponential growth function

a = initial amount

r = growth rate

t = number of time intervals

For given example,

initially a bacteria population (a) = 10,000

Five days later, they find that the population has doubled.

d = 5, f(5) = 20,000

Assuming it grows exponentially, we find the growth rate of a bacteria population by using the formula of exponential growth function.

[tex]\Rightarrow f(d) = a\times(1 + r)^{d}\\\\\Rightarrow f(5) = 10000\times (1+r)^5\\\\\Rightarrow 20000=10000\times (1+r)^5\\\\\Rightarrow 2=(1+5)^5\\\\\Rightarrow 1+r=\sqrt[5]{2}\\\\\Rightarrow 1+r = 1.15\\\\\Rightarrow r = 1.15-1\\\\\Rightarrow \bold{r = 0.15}\\\\\Rightarrow \bold{r=15\%}[/tex]

This means, the exponential growth function would be,

[tex]\bold{f(d) = 10000\times(1+0.15)^d}[/tex], where d represents number of days.

Answer: The medians the middle, so you put in order to 2, 11, 33, 41, 44, and 49. Then, you just pick the number in the middle and since it's 33 and 41, you add them together then divide by 2 and you answer is 37. I hope this helps you!

Answer:

it's -63

good luck if you want explanation comment

Answer: 63

Step-by-step explanation:

All triangles' angles added up should be 180 degrees, so 70+47=117 and 180-117=63.

180 = a+b+c

180 = 47 + 70 + c

180 - 47 - 70 = c

or,

180 - (47+70) = c

Answer:

  11 73/78 ≈ 11.9359   (not 14)

Step-by-step explanation:

The similarity statement tells us ...

  QS/QR = FG/FH

  QS = QR·FG/FH

  13x -14 = 154(55/60) = 847/6

Adding 14 = 84/6, we have ...

  13x = 931/6

  x = 931/78 = 11 73/78 . . . . . . . divide by 13

__

Comment on the question

You get a nice integer answer for x if the similarity statement is written ...

  ∆FGH ~ ∆QRS . . . . . . . note the letters are in alphabetical order

Then you have ...

  QS/QR = FH/FG

  13x -14 = 154(60/55) = 168

  13x = 182

  x = 14

This nice answer to a nice similarity statement leads us to believe the question has an error in it.

We suspect you are expected to provide x=14 as the answer, even though that is NOT the answer to the question as written. You may want to discuss this with your teacher.
