A bag of pennies weighs 5.1 kilogram. Each penny weighs 2.5 grams. About how many pennies are in the bag?
A. 20
B. 200
C. 2,000
D. 20,000
Answer:2K
Step-by-step explanation:since one kilogram is 1,000 grams and there 5.1 kL it’s 5,100 grams so about 2,000 pennies
Answer:
C, 2000
Step-by-step explanation:
First convert kilo grams into grams, there are 1000 grams in 1 kilogram, the prefix "kilo" means thousand. if you multiply 5.1 times 1000 you will get 5100 grams in the bag. Divide this by the weight of the penny, 2.5, to get 204. The question asks "About how many pennies are in the bag?" so we know to round to the closest answer being c.
How do i measure the diameter of a circle?
Answer:
Step-by-step explanation:
If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter
there’s 2 basic cases you’ll see to find the diameter (a line that basically cuts the circle in half)
you’ll either be given the radius (the distance between the center of the circle to any point on the circle) or the circumference (the perimeter of the circle)
so you have two equations:
diameter= 2*radius
circumference= diameter * pi
if they gave you the radius, simply multiply by 2 as the first equation states. if they give you the circumference, divide the circumference by pi (which is approx. 3.14)
mmmmm i dont know how to do this
Answer:
See the answer below.
Step-by-step explanation:
The Pythagoras theorem for a right triangle is
c^2 = a^2 + b^2 where c = hypotenuse and a, b are the legs of the triangle.
3 positive integers which fit this formula are called Pythagorean Triples.
3,4 5 are a triple because 5^2 = 3^2 + 4^2 ( 25 = 9 + 16).
and also 17^2 = 15^2 + 8^2 ( 289 = 225 + 64).
Step-by-step explanation:
Pythagorean theorem is [tex]a^{2} + b^{2} =c^{2}[/tex] (c being the largest number)
Pythagorean triples are 3 positive numbers that make this equation true.
let's start with 3,4,5
3²+4²=5²
9+16=25
25=25
Since it's true, it's a triple.
Now 8,15,17
8²+15²=17²
64+225=289
289=289
This is also true, so it's also a triple
Hope this helps!

8x + 3 (3 - x) = 34
A. x = 5
B. x = 2
C. x = 8
D. x = 4
Answer:
A. x=5
Step-by-step explanation:
8x+3(3-x)=34
We move all terms to the left:
8x+3(3-x)-(34)=0
We add all the numbers together, and all the variables
8x+3(-1x+3)-34=0
We multiply parentheses
8x-3x+9-34=0
We add all the numbers together, and all the variables
5x-25=0
We move all terms containing x to the left, all other terms to the right
5x=25
x=25/5
x=5
I think this is correct.
Answer: its A; x=5
Step-by-step explanation:
8x+3(3-x)=34
distribute the 3 through the parentheses
8x+9-3x=34
then add the like terms
5x+9=34
subtract the 9 to the 34
you shoud get
5x=25
then divide the 5 on both sides and you get your answer of x=5
