0.5 is the first way
1/2 is the second way
50% is the third way.
Hope that helps bud :).
1. 672/12 = 56
2. 1440/16 = 90
3. 784/7 = 112
Answer:
D/2=r
Step-by-step explanation:
Since we want r to be by itself what we can do is divide 2 on both sides so 2 can cancel out on 2r and when you divide on both sides your left with d/2=r
Answer:
A.
Step-by-step explanation:
Y=mx+c
c=intercept =-2
Gradient(m) =2/1=+2
Y=2x-2
In order to solve for a nth term in an arithmetic sequence, we use the formula written as:
an = a1 + (n-1)d
where an is the nth term, a1 is the first value in the sequence, n is the term position and d is the common difference.
First, we need to calculate for d from the given values above.
<span>a1 = 38 and a17 = -74
</span>
an = a1 + (n-1)d
-74 = 38 + (17-1)d
d = -7
The 27th term is calculated as follows:
a27 = a1 + (n-1)d
a27= 38 + (27-1)(-7)
a27 = -144 -----------> OPTION D
