(going to number these 1-4 starting with the top one)
1. 6:5
2. 1:3
3. 4:3
4. 1:2
Answer:
116
Step-by-step explanation:
82 brownies sold for $1 each is $82 in total
140-82=58
each cookie is sold at $0.5 so we need to multiply the rest of the cash by 2
58×2=116
so he needs to sell 116 more cookies to reach his goal
I will take the sugestion, so 85 units per month (100 is full capacity)
so while doing maintinance, the 6 months is wasted, 0 ouput, basically 85*6=510 lost
now we have to see how many months x it takes for the output to match
the output that would have been is
510+85x
the output now is 120x
so
510+85x=120x
minus 85x both sides
510=35x
divide both sides by 35
14.57=x
round up
15 months needed
A) fifth = 5/5 (this is a fraction) 1/5 is 1 fifth of 1. Get what i'm saying? So then the will be <u>5 fifths in a whole
</u>
B) ok turn 2 1/3 into a improper fraction and that will be <u>7/3</u>
C) ok so 4 (a whole number) is 20/5 so you divide 20/5 with 2/5 (ignore this if you don't know what i'm talking about this is in middle school) so that will = <u>10</u>
