Answer:

19v - 18

Step-by-step explanation:

Hello!

v - 6(-3v + 3)

Distribute the -6

-6 * -3v = 18v

-6 * 3 = -18

v + 18v -18

Combine like terms

19v - 18

The answer is 19v - 18

Hope this helps!

Answer:

V=6;v=1

Step-by-step explanation:

(V-6)(-3v+3)

-3v^2+3v+18v-18

-3v^2+21v-18

Multiple it by minus one we will get

3v^3-21v+18

Now breaking by midterm

3v^2-18v-3v+18

3v(v-6)-3(v-6)

(V-6)(3v-3)

V=6;v=1

A clock loses 2 minutes every 6 hours. At 3:00 pm, the clock is set to the correct time and allowed to run without interference.
avanturin [10]

Answer:

24 minutes, 2:36 pm

Step-by-step explanation:

As working with hours is difficult because it does not use decimal system, lets work with minutes, not hours.

So, the clock is set to work normal at 3:00 pm and we need to get the minutes lost three days after. We know that, as 1 day has 24 hs, 3 days have 72 hours. Then, as our clock loses 2m after every 6 hs, we need to see how many 6hs are there in 72 hs. We do this bt dividing 72 by 6:

72/6 = 12

So, in 72 hours we will have 12 periods of 6hs. As our clock loses 2m after every 6 hs, in 3 days we will lose 2m 12 times. This is:

12 * 2 = 24

The clock loses 24 minutes.

Now we need to see the time it will read.

If there were no problems, the clock should read 3:00 pm after 3 days (72hs). But, as it lost 24 minutes, it will read 2:36 pm, it is, 24 minutes before 3:00 pm.

Use the pythagorean theorem, we get that the height, or x, is

sqrt(22x22-18x18) = sqrt(484-324) = sqrt(160) = 4sqrt(10) = 12.6 m

Sarah says that you can use the area of a
dimulka [17.4K]

Answer:

Sarah is Correct

Step-by-step explanation:

If we are given the area of a circle as 44 Square Centimeter, we know that:

Area of a Circle=\pi r^2

Circumference of a Circle =2\pi r

Therefore, from the area, we can obtain the value of the radius to calculate the circumference of the circle:

\pi r^2=44\\r^2=\dfrac{44}{\pi} \\r=\sqrt{\dfrac{44}{\pi} }

Therefore:

Circumference of the circle=2\pi \sqrt{\dfrac{44}{\pi} }

=23.51 centimeters.
