Answer: 14:30

Step-by-step explanation:

19:13 - 4.43 looks easy, but time expressed in 24-hour format is a base 60 calculation in the decimal portion. It only contains values between 0 and 59.

I broke it it down to simplify:

1) Take 13 minutes off the 19:13 to make it 19:00.

2) Then take the same 13 minutes off the 4.43, which would make it 4.30 (4 1/2 hours)

3) Now take off the 4.30 from the 19:00. The 4 portion of 4.3 can be removed: 19:00 - 4:00 = 15:00. Then remove the 0:30 portion (1/2 hour), which would leave 14:30.

14:30 plus 4:43 = 18:73, but the 0:73 must convert to 1:13 to account for the 60 minutes/hour format

What are the possible values of x for the following functions?

stiks02 [169]

What can a denominator never be?

0

so, we need to figure what x can't be... the only way to multiply 2 things together to get 0 is if one or both are zero.

so, what x values make our denominator 0?

to figure this out, we need to set (x-1)(x-2)=0

now we split and solve.

$x - 1 = 0 \\ x - 2 = 0$
so when x is 1 or 2 the function doesnt make sense.

but, x can be every other number and it does, so the answer is
ALL REAL NUMBERS not equal to 1 or 2

10 points! doing brainliest! Do all 3<br><br><br>

Answer:

12) $\frac{7}{3} = \frac{b}{18}$

$3b = 126$

$\frac{3b}{3} = \frac{126}{3}$

$b = 42$

13) $\frac{3.6}{m} = \frac{1.2}{3.6}$

$1.2m = 12.96$

$\frac{12m}{12} = \frac{12.96}{12}$

$m = 10.8$

14) $\frac{16}{10} = \frac{n + 2}{5}$

$80 = 10n + 20$

$80 - 20 = 10n +20 -20$

$60 = 10n$

$\frac{60}{10} = \frac{10n}{10}$

$n = 6$

Circumference = 12.6yds find the radius.

Studentka2010 [4]

Circumference= 2 times pi times radius
c=2pir
divide both sides by 2pi
c/(2pi)=r
c=12.6
12.6/(2 times pi)=12.6/2 times 1/pi=6.3 times 1/pi=6.3/pi

radius=6.3/pi=aprox (pi aprox 3.14) 2
