The coordinates of the point (-10, -3) after a 180 degree clockwise rotation about the origin will be (10, 3).

As, we have a point which is in negative side after we turn it clockwise direction it will move to positive side so the coordinates will become positive.

The coordinates would be (10, 3)

If you plot these points and rotated 180 degrees, you get the same axes only all positives become negatives and vice versa.

Rounded to the nearest thousand of 275,608

olga nikolaevna [1]

The thousandths place in 275,608 is the 5. Depending on the next number (which in this case is the 6) it will either round up or down. Since the next number is 6 and it's 5 or bigger, the 5 will round up. So your final answer is 276,000.

"a u.S. 1-cent coin (a penny) has a diameter of 19 mm and a thickness of 1.5 mm". Assume the coin is made of pure copper, whose

choli [55]

the question is Calculate the value of the copper in the coin

Step 1

Find the volume of the coin

we know that

the volume of a cylinder is equal to

$V=\pi r^{2}h$

where

r is the radius of the coin

h is the thickness of the coin

in this problem we have

Diameter=19 mm=1.9 cm

r=D/2------> r=1.9/2=0.95 cm

h=1.5 mm=0.15 cm

substitute the values in the formula

$V=\pi*0.95^{2}*0.15=0.425\ cm^{3}$

Step 2

Find the mass of copper in the coin

we know that

the density is equal to

$Density=mass/volume$

Solve for the mass

$mass=Density*volume$

we have

$Density=8.9\ gr/cm^{3}\\Volume=0.425\ cm^{3}$

substitute in the formula

$mass=8.9*0.425=3.785\ gr$

Step 3

Find the cost

we know that

the market price of the copper is $2.15 per pound

1 pound=453.592 grams

convert gram to pounds

3.785 gr=3.785/453.592=0.0083 pounds

0.0083*$2.15=$0.018=$0.02

therefore

the answer is

$0.02

luna has $50 when she got to the carnival. after 12 rides, she had $26. what was the price of each ride?

stellarik [79]

Answer:

Step-by-step explanation:

Lets see how much money she spent first.

$50 - $26 = $24

Now that we know she spent $24 we can divide 24 by twelve which will tell us how much each ride costs

24 / 12 = 2

She spent $2 on each ride
