Answer:
All possible dimensions are: 1ft × 24ft = 24
, 2ft × 12ft = 24, 3ft × 8ft = 24, 4ft × 6ft = 24, 6ft × 4ft = 24, 8ft × 3ft = 24, 12ft × 2ft = 24, or 24ft × 1ft = 24.
Step-by-step explanation:
With the assumption that the sidewalk has a rectangular shape:
Area of a rectangle = length × width
From the question, the total area = 24 .
⇒ length × width = 24
So, all possible combinations are:
i. 1 ft × 24 ft = 24
ii. 2 ft × 12 ft = 24
iii. 3 ft × 8 ft = 24
iv. 4ft × 6 ft = 24
v. 6ft × 4ft = 24
vi. 8ft × 3ft = 24
vii. 12ft × 2ft = 24
viii. 24ft × 1ft = 24
Answer:
60 degrees
Step-by-step explanation:
the triangle is an equilateral triangle
sum of angle in a triangle is 180
therefore,
x + x + x = 180
3x = 180
divide both sides by 3
x = 60 degrees
The first quiz (4/5 with 15 questions)
on that quiz, Kelly got 12/15 questions correct and the other quiz, she only got 10/12. since 12 is a higher number than 10 it means the answer is the first quiz.
You have to take 8000 & multiply is by .03 then add that # to 8000 then take what ever that product is and multiply it by .03 and add that. repeat 4 times the answer should be : $9004.1
Answer:
The pump should be added by 8PM
Step-by-step explanation:
An oil tanker can be emptied by the main pump in 4 hours.
An auxiliary pump can empty the tanker in 11 hours.
the main pump is started at 7 PM,and we have 10 PM - 7PM = 3 hours to empty the tank.
So we have to look for the combined rate of the both pumps .
Let's say the volume= x
Rate of first pump= x/4
Rate of second pump= x/11
The rate will be added together
Combined rate= x/11 + x/4
Combined rate= 15x/44
But they have three hours to complete their pump
15x/44 = 3
X=1.0227
The pump should be added by 8PM
