Answer: (3 , 7)
Step-by-step explanation: When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative. Since x and y are already negative, they become positive due to the double negative rule.
Remove the vine, it is causing the population to decrease. No amount of animals etc. will be able to take care of the vine if the population is already decreasing.
1. Remove the vine.
1 percent of $270 is 2.70 (you just move the decimal point). then multiply your 1 percent by 24 and you have the answer. I get $64.80, doing it on paper.
Add the 24 percent to the original price and you have your retail price: $334.80. If you have a calculator, check my maths.
Answer:
The perimeter or circumference of a half mirror = 37.68 cm
Step-by-step explanation:
- The diameter of circular measure = 24 cm
We know that the perimeter of a circular shape is called the 'circumference', with the formula
- Circumference of a circle = C = 2πr
When the mirror is cut into half, the diameter gets half as well.
- Thus, the diameter of a half mirror = 24/2 = 12 cm
We know that radius = r = diameter / 2 = 12/2 = 6 cm
Thus, the perimeter of half of the mirror = C = 2πr
= 2(3.14)6
= 37.68 cm
Therefore, the perimeter or circumference of a half mirror = 37.68 cm
14-8=6, so 8 balls balance with 6 balls and 20 grams. From this you know that 2 balls=20 grams, simply divide this by 2 to get the weight of one ball which will weigh 10 grams.
