Answer:
$82 sundaes
$74 banana split
Step-by-step explanation:
Step one :
Given data
Cost of sundaes =$2 each
Cost of banana split =$3 each
Let the number of sundaes bought be x
And the number of banana split bought be y
The total is x+y
The shop sold 8 more Sundaes than the Banana split
x=8+y—-------1
Total amount made = $156
Therefore the system of equation for the situation is
x=8+y----—----------1
2x+3y=156---------2
But x=8+y
8+y+y=156
8+2y=156
2y=156-8
2y=148
Divide both sides by 2
y=148/2
y=74
On That day they sold $74 banana split
And also they sold x=8+74=$82 sundaes
A = (√3)/4 x s²
s = 9
A = (√3)/4 x 9²
A = (√3)/4 x 81
A = (81√3)/4
Answer: 0.0476 miles
Step-by-step explanation:
Daurie rides on her motorcycle for 252 miles on 6 gallons of gas. We will determine the unit rate in gallons. It means the number of miles that her motorcycle on one gallon of gas
Distance travelled on one gallon of gas would be 6/252 = 0.0238 miles
At this rate of 0.0238 miles per one gallon of gas, the distance travelled on 2 gallons of gas would be
2 × 0.0238 = 0.0476 miles
