Answer: 7/20 = 0.35 or 35%. 5/9 = 0.55555.... or 55.5555....%
Step-by-step explanation: 7/20 is the same as 0.35 when you divide them: 20 goes into 7 zero times. Bring down a zero once you have 0. in the quotient place. 20 goes into 70 three times. 3 multiplied by 20 is 60. 70 minus 60 is 10. 20 goes into 10 zero times. Bring down another zero. 20 goes into 100 five times. So we now have 0.35. Move the decimal place two spaces to the right to get the percent: 35%.
The same goes for 5/9: 9 goes into 5 zero times. Place a decimal after 0 and bring down a zero. 9 goes into 50 five times. 9 times 5 is 45. 50 minus 45 is 5. We can see a pattern here, so we can assume the next number will also be 5. We now have 0.55555.... as a percent, move the decimal place two spaces to the right: 55.56% rounded.

Answer:
23x + 18y = 1446
x + y = 72
Step-by-step explanation:
The bakery made $1446 total. We represent this as the cost of each cake ($23) times the number of cakes sold (x) plus the cost of each dozen cupcakes ($18) times the number of cupcakes sold (y).
Thus, 23x +18y = $1446.
The bakery sold 72 items total. We represent this as the number of cakes sold (x) plus the number of each dozen cupcakes sold (y).
Thus, x + y = 72.
Answer:
48%
Step-by-step explanation:
The conditional probability definition applies.
P(med | cold) = P(med & cold) / P(cold)
The probabilities are the table numbers divided by the total of all numbers in the table (100). Since that dividend is the same for all, we can basically ignore it and just use the table numbers.
P(med | cold) = (12)/(8+12+5) = 12/25 = 48/100
P(med | cold) = 48%
