Answer is 7/10 (7 over 10)
Look at the gradient of both the equations (the x multiplier, usually known as m), and there are a couple of rules:
Parallel: The gradients are identical
Perpendicular: Look at the gradients as fractions. To get the perpendicular to a gradient you flip the fraction and change the sign. If this is the case for the two gradients, then they are perpendicular.
Answer:
The larger number is 40, and the smaller one is 23.
Step-by-step explanation:
Let x be the larger number.
Let x - 17 be the smaller number.
x + (x - 17) = 63
2x - 17 = 63
2x = 80
x = 40
Hence, the smaller number is 40 - 17 = 23.

There is 90 deaths per day.
First it tells us 32,400 people died in 2015, which also mean that many people died that year.
We have to find the number of people died each month first.
32,400÷12 because 12 is the total number of months in a year.
2700 people died in a month, not we need to find how many people died each day so we divided it by 30 and we get
90 deaths per day.
Answer:
The investment firm's total profit is $4,000
Step-by-step explanation:
The Profit from Company A = 11% * $8,000
= 11 * $8,000/100
= $880
The Profit from Company B = 13% * $24,000
= 13 * $24,000/100
= $3,120
The total profit = $880 + $3120
= $4,000
Thus, the investment firm's total profit is $4,000
