8/3 is an improper fraction, to make it proper you find out how many times 3 goes into 8 (which is 2). So then you have 2 and two times 3 is 6. This does not equal 8 yet so you do 8-6=2 You put this number over the denominator 3. So your final answer is 2 2/3.
The number 7 cannot be used to write related number sentences because it wouldn't fit into the equation & make it true.
9 + 5 = 14
5 + 9 = 14
14 - 5 = 9
14 - 9 =5
Nowhere in any of these equations can the #7 go in, & make these number sentences true.
Hope this helps & makes sense ! (:
Answer:22
Step-by-step explanation:
m = ρ v
m = (0.492 g / mL) * 163.5 mL
m = 80.442 g
rounded to nearest hundredth:
m = 80.44 g
You will need to use formula x= -b/2a because the min value will by the vertex of function.
x= -(-92/(2*.2)) = 230
then plug in x value
C=0.2(230)^2-92(230)+11,165= 585
