Answer:
y = 7
Step-by-step explanation:
Equate the equation to equal 0.
8(y-7) = 0
Open up the bracket:
8y - 56 = 0
Add 56 to both sides:
8y = 56
Divide both sides by 8:
y = 7
<u>Scale - Convert to meters and reduced it to 1 cm:</u>
3 cm : 1000 cm | GIven
3 cm : 10m | Convert 1000cm to 10m
1 cm: 10/3 m | Find 1 cm
<u>Convert the dimensions to the actual:
</u>
7.5 cm = 7.5 x 10/3 = 25m | Convert 7.5cm on map to actual distance
15 cm = 15 x 10/3 = 50m | Convert 15m on map to actual distance²
<u>Find area of the actual pool:</u>
Area = 25 x 50 = 1250 m² | Use the formula Area = Length x Width
Answer: 1250 m²
Answer:
Part #1: 13/15
Part #2: 11/45
Part #3: 23/45
Step-by-step explanation:
Part #1: So add the total amount of coins: 4 + 7 + 12 + 22 = 45
Since the only coins that are at most $1 are: The $1 coins, 50 cent coins, and the 20 cent coins. That is a total of 7 + 12 + 20 = 39
39/45
13/15
Answer: 13/15
Part #2: Since the only coins that are $1 or $2: The $1 coins and the $2 coins. That is a total of 4 + 7 = 11
11/45
Answer: 11/45
Part #3: Since the only coins that are at least 50 cents: The $1 coins and the $2 coins and the 50 cent coins. That is a total of 4 + 7 + 12 = 23
