Answer:
100%-10%=90%
90%=36$ what about 10%=4$
36$+4$=40$
Answer:
Step-by-step explanation:
They are all true
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
#1 is b and #2 is also b ,, i think..so sorry if i’m wrong!
Area of circle = pi * r^2
pi * (3.25)^2 = 33.18307
Rounded = 33.18
Solution: area = 33.28 yd^2
