The total amount is 0.75 inches or 3/4 inches.
Answer:
50
Step-by-step explanation:
Sum Even numbers
n = 50
d = 2
a1 = 2
The last number is
an = a1 + (n-1)d
an = 2 + (50 - 1)*2
an = 2 + 49 * 2
an = 2 + 98
an = 100
Sum of the even numbers
Sum = (a1 + a50)*n/ 2
Sum = (2 + 100)*50/2
sum = 102 * 25
sum = 2550
Sum of the first 50 odd numbers
a1 = 1
n = 50
d = 2
l = ?
Find l
l = a1 + (n - 1)*2
l = 1 + 49*2
l = 99
Sum
Sum = (1 + 99)*50/2
Sum = 2500
The difference and answer is 2550 - 2500 = 50
Answer:
m = -1.25
Step-by-step explanation:
Slope = (Y2-Y1) = (9-14) = (-5) = -1.25

Answer:
∠a=40°
Step-by-step explanation:
complement of angle a=90-a
supplement of angle a=180-a
90-a=1/2(180-a)-20
multiply by 2
180-2a=180-a-40
180-180+40=-a+2a
a=40
