What you know is 
area=706.5in^2
formula is 3.14*r*r
what to do is set up an equation
706.5=3.14*r*r
after you divide both sides by 3.14 to cancel it out your left with 
225=r^2 
then you would take the root of both sides to get 
r= 15 , -15

in a sale there is twenty five per cent off all prices a bed cost £33 in the sale how much was it before the sale ?
goldfiish [28.3K]
The original price was 100% and the sale was -25%
100% - 25% = 75%
This means 75% = £33
75% = 3/4
If we divide the sale amount by 3 and them multiply by 4, we will get the original amount.
£33 / 3 = £11
£11 x 4 = £44

Which statement is FALSE for this situation?
irinina [24]

Option C: Company A's payments grow by a factor of 2

Explanation:

We need to determine the statement which is false.

Option A: A linear function represents Company A's payments.

From the table, it is obvious that the y - value increases by adding 5000.

Thus, the payments of company A can be written in linear function.

Hence, the statement a linear function represents Company A's payments is true.

Therefore, Option A is not the correct answer.

Option B: An exponential function represents Company B's payments.

From the table, it is obvious that the y - value increases by a factor of 2.

Thus, the payments of company B can be written in exponential function.

Hence, the statement an exponential function represents Company B's payments is true.

Therefore, Option B is not the correct answer.

Option C: Company A's payments grow by a factor of 2.

From the table, it is obvious that the y - value increases by adding the 5000.

Hence, the statement Company A's payments grow by a factor of 2 is false.

Therefore, Option C is the correct answer.

Option D: Company B's payments grow by a factor of 2.

From the table, the y - value increases by a factor of 2.

Hence, the statement Company B's payments grow by a factor of 2 is true.

Therefore, Option D is not the correct answer.

What is -11+6x+25-3x
evablogger [386]

Answer:

3 x + 14

Step-by-step explanation:

Simplify the following:

6 x - 3 x - 11 + 25

Grouping like terms, 6 x - 3 x - 11 + 25 = (6 x - 3 x) + (-11 + 25):

(6 x - 3 x) + (-11 + 25)

6 x - 3 x = 3 x:

3 x + (-11 + 25)

25 - 11 = 14:

Answer:  3 x + 14
