Answer:
D
Step-by-step explanation:
30.20 * 15% (or 0.15) = 4.53
4.53 is about 4.50
Answer:
The given equation will have value less than 100 whenever the value of b is greater than 12.89
Step-by-step explanation:
For the given equation, p(b) = 520 ×
to have a value less than 100 we can establish inequality as:
p(b) < 100
or, 520 ×
< 100
or,
×
< 
or,
< 
or, ㏒ (
) < ㏒ (
)
or, b× ㏒ 0.88 < ㏒ (
)
or,
< b
or, 12.89 < b
Hence for the equation to have value less than 100, b must be greater than 12.89.
Given:

To find:
The value of x.
Solution:
We have,

To find the value of x, we need to isolate x on one side.
Subtract 2b from both sides.

Divide both sides by -3. On multiplying or dividing an inequality by a negative number, we need to change the sign of inequality.


The required inequality for x is
.
Therefore, the correct option is A.
For the first marble would be: 2/11
For the second: 3/11
