Answer
If d equals diameter the radius is 9
Step-by-step explanation:
Answer:
Negative
Step-by-step explanation:
Assume that you mean if c÷d is positive or negative when c > 0 and d < 0
c > 0 means that c is positive
d < 0 means that d is negative
positive divides negative is always negative.
Thus, c÷d is negative when c > 0 and d < 0
Answer:
0.8 or 4/5
Step-by-step explanation:
Answer:
0.375
Step-by-step explanation:
Listing the factors of 30
1, 2, 3, 5, 6, 10, 15, 30 ← that is 8 factors
There are 3, 2- digit factors, that is 10, 15, 30
Thus the probability of choosing a 2- digit number factor is
= 0.375
Step-by-step explanation:
x-9≤2(9-x)
distribute
x-9≤18-2x
add 2x on both sides
3x-9≤18
add 9 on both sides
3x≤27
divide by 3
x≤9
