Answer:
Step-by-step explanation:
A(7,1), B(5,-6)
(AB)² = (-6-1)² + (5-7)² = 53
AB = √53
Answer:
76
Step-by-step explanation:
We were given The equation below which shows how much money was raised with t tickets sold. $836 = $11t
Mathematically, unit rate is How much of something per 1 unit of something else
$836 = $11t
Then we can get the value for "t" as
t= 836/11
t= 76
Hence, Unit rate is 76
speed of plane flying east = x
speed of plane flying west = x+75
total speed = 2x+75
distance after 4 hours ( 7-3) = 8x+300
8x+300 = 5460
8x = 5160
x = 5160/8 = 645
speed of plane flying east = 645 km/h
You go to a restaurant and your bill is $35.00. Your service was excellent so you leave a 20% tip. What was the total amount paid for the bill including the tip?
10%=$1 for every $10
15%=$1.50 for every $10
20%=2% for every $10
10% of the bill would be $3.50(move the decimal to the tens place)
15% of the bill would be $5.25( halve the 10% and add it to the original 10% tip; $3.50+$1.75)
20% of the bill would be $7.00(double the 10% tip)
