Answer:
Area = (a² -5a) in²
Perimeter = (4a -10) in
Step-by-step explanation:
Let the length of the rectangle be a.
Given that, its width is 5 in less than the length.
So,
length ⇒ a
width ⇒ (a - 5)
First, let's find the area of the rectangle.
Area = length × width
Area = a ( a - 5 )
<em>Solve the brackets.</em>
Area = <u>(a² -5a) in²</u>
<u />
Now, let us find the perimeter of the rectangle.
Perimeter = 2 ( l + w )
Perimeter = 2 ( a + a - 5 )
Perimeter = 2 ( 2a - 5 )
Perimeter = <u>(4a -10) in</u>
Answer:
The meet at first time at starting point after 336 seconds,
Vanu have completed 7 laps while Tanuj has completed 6 laps.
Step-by-step explanation:
Given that Venu and Tanuj take 48 seconds and 56 seconds to
complete a lap respectively.
To meet them again at the startiong point, the time taken must be multiple of 56 and 48.
So, the minimum time required to meet them again at the startiong point is time taken for first time meet.
Time taken to first time meet is the smallest number which can be divided by 56 and 48, i.e the lowest common factor (LCM) of 56 and 48 which is 336 seconds or 5 minutes 36 seconds.
Number of laps by Venu
Number of laps by Tanuj
Answer: Ash
Step-by-step explanation:
Convert both into a percentage so it is clearer
Lia- 48%
Ash- 48.57%
17)mixed form x=5 7/17 exact form 92/17
18)x=49
19)mixed form x=30 6/7 exact form x=216/7
20)mixed form x=2 1/4 exact form x=9/4
Answer: 7 Answers Incorrect
Step-by-step explanation:
86% may be written as (86/100) or as 0.86.
Since "it's a ratio (sic.) problem," then:
86/100 = correct/50
correct = (86/100)*50 (multiply both sides by 50)
correct = 43
And, 50-43 = 7 incorrect
