Answer:
b = {0, 1, 2, 3, 4, 5}
Step-by-step explanation:
The domain of a function is simply all the possible values the independent variable can assume that the function will work and will give a real number.
In this question, we have:
m = 45 – 8b
b is the independent variable because the money, m, depends on the number of books, b, bought.
Since we can't have negative value for m as it represents an amount of money, then the values b can assume can be gotten through:
45 – 8b = 0,
8b = 45
b = 45/8 = 5.625
For the m, money, to remain positive b shouldn't go beyond 5.625
Also we should note that b, books, can't be a negative (no such thing as negative books) or a fractional value (no such thing as buying parts of a book) as well. Therefore, b = {0, 1, 2, 3, 4, 5}
Answer:
10 > x > 100
Step-by-step explanation:
because x must be less than 10 (10 > x) or greater than 100 (x > 100)
Answer:
C; About 100 in².
Step-by-step explanation:
This problem may seem confusing because they talk about tabletops, but that is just their choice of representing circumference of a circle.
<u>The formula for finding the circumference of a circle is 2πr:</u>
In that case, we can substitute 16 for our r.
Likewise, the tabletop will be if we were to multiply it by π.
Thusly, the table top's circumference can be estimated as .

So 5/8 of $24
5/8 * 24
15
Joshua spent $15.
Hope this helps :)
Answer:
P (not green) = 17/20
Step-by-step explanation:
Given the following number of marbles:
Green : 3
Yellow : 4
Blue : 5
Pink :8
Total number of marbles = 3 + 4 + 5 + 8 = 20 marbles
if we draw 1 marble at random from the bag, the probability that the marble IS green,
P(Green) = 3/20
The probability that the marble is NOT green is,
P(Not Green)
= 1 - P(Green)
= 1 - 3/20
= 17/20
