Answer:
B.) 27ft
Step-by-step explanation:
The labeled points given: (5,18) and (1.5, 7.5)
Slope = (18 - 7.5)/(5-1.5) = 10.5 / 3.5 = 3
A linear model:
y - 18 = 3(x - 5)
y - 18 = 3x - 15
y = 3x + 3
If x = 8 seconds then the distance in feet (y) would be: (plug in x = 8 into the equation y = 3x + 3)
y = 3(8) + 3
y = 24 + 3
y = 27 ft
Answer:
B.) 27ft
Step by step explanation:
1) To find the sales tax, 70 is your 100%
So since you’re trying to find the sales tax, you add the 3% to the 100%, which gets you to 103%.
2) Now you turn 103 to a decimal (if you want to. This is my preferred option to make this easier)
3) 103 turns into 1.03.
4) Now you multiply 70 and 1.03.
Answer: $72.10
Answer: the height of the melted candies in the pot is 12.2 mm
Step-by-step explanation:
The formula for determining the volume of a square base pyramid is expressed as
Volume = area of base × height
Area of the square base = 12² = 144 mm²
Volume of each pyramid = 15 × 144 = 2160 mm³
The volume of 100 pyramid shaped chocolate candies is
2160 × 100 = 216000 mm³
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Since the pyramids was melted in the cylindrical pot whose radius is 75 mm, it means that
216000 = 3.14 × 75² × h
17662.5h = 216000
h = 216000/17662.5
h = 12.2 mm
15ft is the length of the rectangle
