Answer:
for 1. it is 99 and for 3. it is 343.75
Step-by-step explanation:
for 1. you have to just multiply the length with width
for 3. you have to add both bases (35+20) and multiply the height (55 x 12.5) to it and then divide it by 2 (687.5 / 2)

Answer:

Step-by-step explanation:
Given
per hour for 40 hours, weekly
per hour over 40 hours, weekly
Required
Determine f(x)
From the question, we have that
x represents hours worked
Earnings in 40 hours is: 40 * 10 = $400
Hours over 40 will be: x - 40
So, earnings during this time will be: (x - 40) * 15
Total earnings is:




Answer:

Step-by-step explanation:
Parallel lines have equal slopes
The product of the slopes of perpendicular lines = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
All the equations given are in slope- intercept form
y = 2x + 1 → with m = 2
y =
x - 4 → with m = 
y = x + 1 → with m = 1
y = -
x - 3 → with m = - 
y = 10 + x → y = x + 10 → with m = 1
Thus
y = x + 1 and y = 10 + x are Parallel since both have m = 1
y = 2x + 1 and y = -
x - 3 are Perpendicular since 2 × -
= - 1
