3 sec = 36 feet
6 sec = 72 feet
9 sec = 108 feet
(b)
After 3 seconds, the elevator is 144 feet above the first floor
After 6 seconds, the elevator is 108 feet above the first floor
After 9 seconds, the elevator is 72 feet above the first floor
(c) It takes 15 seconds for the elevator to get to the first floor
(d) The basement floor is 48 feet below the first floor
Step-by-step explanation:
31 (a) explanation:
An elevator is 180 feet above the first floor.
Each second, it descends 12 feet.
So the elevator's change in height each second is a decrease of 12 feet towards the first floor.
31 (b) explanation:
If the elevator goes down 12 feet, towards the first floor, in 1 second then;
After 3 seconds it will be 180 feet - 3(12) feet = 144 feet above the first floor
After 6 seconds it will be 180 feet - 6(12) feet = 108 feet above the first floor
After 9 seconds it will be 180 feet - 9(12) feet = 72 feet above the first floor
31 (c) explanation:
If the elevator is 180 feet above the first floor and it takes 1 second to descend 12 feet,
Then it will take: × 1 second = 15 seconds reach the first floor.
31 (d) explanation:
From the first floor it takes 4 seconds to reach the basement floor
Therefore the basement floor is × 12 feet = 48 feet below the first floor

Answer:
Question 2. 12% of 650 = 78
Step-by-step explanation:
100% = 1 in decimal form.
This is because finding 100% of something is the same as multiplying it by 1:
E.g. 100% of 10=10, 10x1 = 10
Therefore to find a percentage of something, we simply need to multiply it by the decimal form of that percentage. For example, if we were finding 50% of 10 (half), 50% in decimal form is 0.5, 10x0.5 = 5
The percentage here is 12%, we can find the decimal form by dividing it by 100, 12/100 = 0.12
So, in order to find 12% of 650, we just need to multiply 650 by 0.12:
650x0.12 = 78
12% of 650 = 78

2/5 divided by 5/6 is? Express ur awnser in the simplest form. DIVIDING FRACTIONS! pls help right away and thx :)
Answers
2/5 x 6/5
= 12/25
or
= 0.48
2/5 divided by 5/6 equals 12/25.
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.
The reciprocal of a fraction is obtained by swapping the numerator and the denominator.
So, to divide 2/5 by 5/6, we multiply 2/5 by the reciprocal of 5/6.
Reciprocal of 5/6 = 6/5
Now, we can multiply the fractions:
[tex]\frac{2}{5} \times \frac{6}{5}[/tex]
[tex]= \frac{2 \times 6}{5 \times 5}[/tex]
[tex]= \frac{12}{25}[/tex]
Therefore, 2/5 divided by 5/6 equals 12/25.

You need at least $40 to buy some notebooks, but your parents don’t want to give you more than $50. Write an inequality representing the possible amount of money you could get.
Answers
m = amount of money you receive
You need at least $40, so that means you need m = 40 or more
So [tex]m \ge 40[/tex] which is the same as saying [tex]40 \le m[/tex]. You flip both sides and also flip the inequality sign as well.
At the same time, your parents won't give you more than $50. So the largest m can get is m = 50. This means [tex]m \le 50[/tex]
-----------------
Combine [tex]40 \le m[/tex] and [tex]m \le 50[/tex] to get the compound inequality [tex]40 \le m \le 50[/tex]
This represents all the possible values of m. We see that m can get as small as m = 40, or as large as m = 50, or anything in between.
------------------
Answer: [tex]40 \le m \le 50[/tex]
