Answer:

C

Step-by-step explanation:

it is C because 8*60=480 minutes

so 480min/25min=19.20 round=19

25(19)-45=430<480 which is true

where as if you use 19 for p it wouln't be true

Answer:

IF TWO VALUES ARE <u>PROPORTIONAL</u> THEY CAN BE CONNECTED IN TERMS OF k BY MAKING THEM IN A STUCTURE OF AN EQAUTION LIKE GIVEN BELOW. HERE AS THE PROPORTIONAL VALUES ARE<u> RADIUS</u> AND <u>CIRCUMFERENCE </u>WE USE THE GIVEN VALUES AND CREATE EQAUTION LIKE BELOW

r=kC

⇒WE CAN TRASNPOSE THIS TO GET

kC/r=0

⇒C/r=1/k

RECIPROCATE IT TO GET

⇒r/C=k

Maybe this will be correct answer

How do you solve this equation: -2m+3=|15+m|
Elden [556K]

Any number inside the modulus sign becomes positive. This means |15+m|=|-(15+m)|=|-15-m| and so we have,

-2m+3=|15+m| \Rightarrow \left \Big\{ {{-2m+3=15+m} \atop{-2m+3=-15-m}} \right

Solving these gives us

-2m+3=15+m \Rightarrow m=-4

-2m+3=-15-m \Rightarrow = m=18

However if we check the second solution in the original equation we obtain -2(18)+3=|15+18| \Rightarrow -33=33. This is false and so m=18 can't be a solution.

Therefore the only solution is m=-4.

(Note: I'm not sure why the second solution didn't work but when there's a modulus sign involved it always pays to check your final answers to be sure. I'll have a think about it but in case you find out before I do, I'd be interested to know in the comments.)

Circle O has a circumference of approximately 44 in. What is the approximate length of the diameter, d? inches
LenKa [72]
The distance around a rectangle or a square is as you might remember called the perimeter. The distance around a circle on the other hand is called the circumference. It is calculated as follows:

C = 2pi(r)

From this, we can solve for r and evetually solve for the diameter.

44 = 2pi(r)
r = 7.00
d = 2r
d = 14
