Answer:
64
Step-by-step explanation:
Step 1: Define
9(a + 2b) + c
a = 3
b = 2
c = 1
Step 2: Substitute and Evaluate
9(3 + 2(2)) + 1
9(3 + 4) + 1
9(7) + 1
63 + 1
64
Answer:
3
Step-by-step explanation:
1/10 is the same as saying 10 times less
Refer to the diagram below
The digit as the first decimal place is worth 1/10
The digit as the second decimal place is worth 1/100 which is 1/10 worth the digit as the first decimal place
Example of two decimal numbers:
2.56 and 2.68
The digit 6 in 2.56 is 6/100
The digit 6 in 2.68 is 6/10
The digit 6 in 2.56 is 1/10 as much as the digit 6 in 2.68
When the dilation is about the origin, the scale factor multiplies every coordinate. That is (considering the x-coordinate) ...
6·k = 3
k = 3/6 = 1/2
The appropriate choice is
1. 1/2
