Answer:
2.34 grams
Step-by-step explanation:
The first 3 digits of the number are 2, 3, 3. The next digit is 5, which is more than 4, so 1 is added to the digit to its left and all digits to the right of the first three are dropped.
2.33 becomes 2.34 because of the 5 in the thousandths place.
Your rounded measurement is 2.34 grams.
Answer:
44
Step-by-step explanation:
x = 4 and y = 12.
5х² - 3у
20x - 3y
80 - 36
44
Yo has to factor since we assume that
if you have xy=0, x and y=0
7n^2-48n+36=0
trial and error
(7n-6)(n-6)=0
set each to zero
7n-6=0
add 6
7n=6
divide 7
n=6/7
n-6=0
add 6
n=6
n=6/7 or 6
ANSWER for the first one:
A=a+b/2*h
A= 4.5+9/2*6
A= 40.5 cm2
ANSWER for the second one:
9*3= 27
3*3= 9
9*3= 27
A= 63 cm2
