Answer:
9 newspapers and 5 magazines
18 newspapers and 10 magazines
27 newspapers and 15 magazines
36 newspapers and 20 magazines
45 newspapers and 25 magazines
54 newspapers and 30 magazines
63 newspapers and 35 magazines
72 newspapers and 40 magazines
81 newspapers and 45 magazines
90 newspapers and 50 magazines
Step-by-step explanation:
You basically just have to follow this formula
9x newspapers and 5x magazines
x can equal literally any positive integer you want!
just make sure you multiply the 9 and the 5 by the same numebr to keep the ratio the same!
Answer:
Circumference = 157 ft
Area = 1962.5 ft^2
Step-by-step explanation:
d = 50
C = pi *d
C = 3.14 * 50
C =157 ft
This is the circumference
The area is found by
A = pi r^2
r =d/2
r= 50/2 =25
A =pi (25)^2
A = 3.14 *25^2
=3.14 *625
=1962.5 ft^2
Answer:
letter C: 100
Step-by-step explanation:
This problem can be configured as an arithmetic progression:
The first value is 10, the ratio is also 10 (the multiples of ten are 20, 30, 40, ...) and the number of terms is 19 (10, 20, 30, ... , 180, 190 -> total of 19 numbers).
So, we can use the following formula to calculate the sum of all these numbers:
Sn = n(a1 + an)
/2
where Sn is the sum, n is the number of terms, a1 is the first term and an is the last one.
The result we want is the average of the sum, so we need to divide Sn by n:
Average = Sn/n = n(a1 + an)
/2n = (a1 + an)
/2 = (10+190)/2 = 200/2 = 100
The correct option is letter C.
You switch the sign of the y coordinate for point b, so the new b coordinate is (-2,1)
No the 4 doesn’t show you need to put 2 and 3
