Answer:
4.3cm
Step-by-step explanation:
the radius of the hemisphere can be determined its volume
volume of a hemisphere = (2/3) x (n) x (r^3)
n = 22/7
r = radius
(2/3) x (22/7) x( r^3) = 165 cm^3
44/21 x r^3 = 165
divide both sides of the equation by 21/44
165 x 21/44
r^3 = 78.75
find the cube root
r = 4.2863 cm
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
the 100th terms, 8 is greater than 6, so add 1 to 2. this give 4.3cm
It will take 10 days to write 20 thank you cards if you write 2 per day.
20/2=10
The answer is -4+x. I had an explanation but bro just threw it out cause I wouldn't get him a pencil
Answer:
You will buy 8 jeans and two shirts.
Step-by-step explanation:
set up a systems of equations
identify your variables
jeans = j (a variable means like 'x')
shirts = s
identify a common way to eliminate a variable
(get a common value in both equations so you can add or subtract to leave on variable in which you can solve for)
