Answer:
y = 8
Step-by-step explanation:
Line1 with points (4, 1) and (0, 0):
slope = (y₂ - y₁) / (x₂ - x₁)
= (0 - 1) / (0 - 4)
= 1/4
Perpendicular line is opposite inverse so original slope 1/4 becomes -4/1 or simply -4.
Line2 with points (1, 0) and (-1, y):
slope = (y₂ - y₁) / (x₂ - x₁)
= (y - 0) / (-1 - 1)
= y / -2
y must equal to 8 for the slope to be -4 as stated above.
She would make 7 of her shots shooting or 7/20 percent which is 35% shooting. You can also multiply 20x0.35 and it will give you 7.
Total length of the board = 30 inch
Length of,
-- First piece = x
-- Second piece = 4x
-- Third piece = 5x
5x + 4x + x = 30
10x = 30
x = 3
Therefore, the lengths of:
-- First piece = 3 inch
-- Second piece = 4*3 = 12 inch
-- Third piece = 5*3 = 15 inch
I just figured it out so I’ll answer it on this account lol.
Q1 = 32, Q2 = 45, Q3 = 52
Interquartile range = 52 - 32 = 20
Range = 68 - 21 = 47
63 miles in 270 minutes will mean that nolan rides his bike at a distance of 63/270 miles in one minute.
there are 60 minutes in an hour. So to find out the distance he covers in 1 hour, 63/270 × 60 will give you 14 miles.
Since the question is asking for the average speed, nolan rides his bike at 14 miles per hour i think.
