First we need to convert 3 3/8 into 1/8ths:
Now, we need to see how many times 3/8 goes into 27/8:
So we know he needs 9 telephone poles
Answer:
D.
Step-by-step explanation:
A is linear, you can figure out that y=x+5
B is linear, y=22(x+1)
C is linear, y=8x+5
D is exponential, y=3ˣ⁺¹
Deriving these formulas is a matter of trial and error if you know you can choose between linear and exponential.
<u>3/4</u> = 1/2 + 1/4
<u>5/8</u> = 1/2 + 1/8
<u>7/12</u> = 1/2 + 1/12
X% of 4 = x*4/100 = 0.04x
y% of 5 = x*5/100 = 0.05y
x% of 4 + y% of 5 = 0.04x + 0.05y
How you express a number, n, as percentage of 11?: [n/11]*100= 9.10n %
Then make n = 0.04x + 0.05y
9.10n %= 9.10[0.04x + 0.05y] %= (0.3656x + 0.455y)%
.
540 is the answer because the doubled the first number to get the second number and multiplyed that by 3 to get the third number
