an elevator traveled from the 10th floor to the 2nd floor in 6 seconds. what was the rate of the elevator in floors per second
The elevator travels 4/3 levels per second, or floors per second.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given, an elevator traveled from the 10th floor to the 2nd floor in 6 seconds.
Elevator cover total distance = 10 -2 = 8 floors
since it took elevator 6 seconds
thus
elevator travels in 6 seconds = 8 floor
elevator travels in 1 seconds = 8/6 =4/3 floor
Therefore, the rate of the elevator in floors per second is 4/3 floor per seconds

What is the product of −3 1/4 and −1 1/2 ? Enter your answer as a mixed number, in simplified form, in the box.
Answer:
Mixed number is [tex]4\frac{7}{8}[/tex] and the simplified form of this mixed number is [tex]\frac{39}{8}[/tex].
Step-by-step explanation:
The two mixed numbers are
[tex]-3\frac{1}{4}=-\frac{13}{4}[/tex]
and [tex]-1\frac{1}{2}[/tex]
= [tex]-\frac{3}{2}[/tex]
Now we will multiply these negative fractions.
[tex](-\frac{13}{4})(-\frac{3}{2})[/tex]
When two negative signs get multiplied they become positive.
= [tex]\frac{13}{4}\times \frac{3}{2}[/tex]
= [tex]\frac{39}{8}[/tex]
= [tex]4\frac{7}{8}[/tex]
Therefore, mixed number is [tex]4\frac{7}{8}[/tex] and the simplified form of this mixed number is [tex]\frac{39}{8}[/tex].

Edwin walks for 2 1/2 hours. He walks 1 2/3 miles in the first hour, 1 3/4 miles in the second hour and 1/4 of the total distance in the last 1/2 hour.What is the total distance Edwin walks?
Answer:
The total distance is 41/9 = 4 5/9 miles
Step-by-step explanation:
Total time is 2 1/2 hours.
First hour, he walks 1 2/3 = 5/3 miles.
Second hour, he walks 1 3/4 = 7/4 miles.
The last half hour he walks 1/4 of total distance. If we call total distance x.
[tex]\frac{5}{3} + \frac{7}{4} +\frac{x}{4} = x[/tex]
Now, we can eliminate the denominator, multiplying by four and by three.
[tex]5*4 + 7*3 + 3*x = 4*3*x\\20 + 21 + 3x = 12 x\\41 +3x = 12x \\41 = 12x - 3x\\41 = 9x\\x = 41/9\\x = 4 \frac{5}{9}[/tex]
Total distance is 4 5/9 miles

What is a rectangle?A rectangle is a plane figure that has an equal size of the opposite side. These sides are called the length and the width.
Mathematically;
The area of the rectangle = Length × width
From the parameters given:
Area of a rectangle = 4 1/6 square meters.The width = 1 1/4 metersUsing the formula for the area of a rectangle, we have:
[tex]\mathbf{4 \dfrac{1}{6} m^2 =length \times 1 \dfrac{1}{4} \ m }[/tex]
[tex]\mathbf{ \dfrac{25}{6} m^2 =length \times \dfrac{5}{4} \ m }[/tex]

John made $195 for 13 hours of work. At the same rate, how much would he make for 17 hours of work?
Final answer:
John's hourly wage is calculated to be $15 per hour. For 17 hours of work at this rate, John would earn $255.
Explanation:
John made $195 for 13 hours of work, which means his hourly wage is the total amount earned divided by the total hours worked. To find John's hourly wage we calculate $195 ÷ 13 hours = $15 per hour. To determine how much he would make for 17 hours of work at this same rate, we multiply his hourly wage by 17 hours.
$15 per hour × 17 hours = $255
Therefore, at the same hourly rate, John would make $255 for 17 hours of work.

A dripping faucet wastes a cup of water if it drips for three minutes. The amount of water wasted varies directly with the amount of time the faucet drips. What is the constant of variation?
A. 1/3
B. 2
C. 1/2
D. 3
Answer:
A. 1/3
Step-by-step explanation:
Suppose x represents the amount of the water ( in cups ) wasted in t minutes,
∵ The amount of water wasted varies directly with the amount of time the faucet drips,
⇒ x ∝ t
⇒ x = kt
Where,
k = constant of variation,
If x = 1, t = 3,
[tex]\implies 1 = k(3)\implies k = \frac{1}{3}[/tex]
Hence, the constant of variation is [tex]\frac{1}{3}[/tex]

The function f(t) = 5*cos ((pi/4)*t) + 11 represents the tide in Dark Sea. It has a maximum of 16 feet when time (t) is 0 and a minimum of 6 feet. The sea repeats this cycle every 8 hours. After six hours, how high is the tide?
A. 11 feet
B. 6 feet
C. 8.5 feet
D. 10.5 feet
After six hours, the tide is 11 feet high.
What is function?"It defines a relation between input and output values.""In function, for each input there is exactly one output."For given question,
We have been given a function [tex]f(t)=5\times cos((\frac{\pi}{4} )t)+11[/tex]
