Answer:
Actual length of wall = 30ft
Step-by-step explanation:
We have scale of a room as 3 inch for 5ft.
We can write scaling factor as:
Scaling factor = 3 /60 (Since 5ft = 60 inches )
Scaling factor = 1/20
Now,
a wall in the blueprint is 18inch.
So actual length of wall can be determined by dividing 18 inch by the scale factor.
i.e actual length of wall = 18 / scale factor = 18 / (1/20)
actual length of wall = 18* 20 = 360 inch = 30ft (Since 360 inch = 30ft)
Hence Actual length of wall = 30ft
<span>a) f(n) is the number of students in your calculus class whose birthday is on the nth day of the year.
f(n) is not invertible because several different days, n, may have the same number of students, f(n). Then for one specific f(n) you cannot determine a unique n.
b) f(x) is the volume in litters of x kilograms of water at 4 degrees celsius.?
f(x) is invertible because each x gives a different f(x), then you can determine unambiguously which f(x) corresponds to each x.

No calculations, but,
Def. of isosceles triangle= two congruent sides.
Partial Quotient is the process of division that engage remainders on the first part of division.
The given situation:
partial quotients to divide 145 by 5.
Let’s start solving,
=> 145 / 5
How many 5 are there in 145
=> 14 / 5 = 2, (2 x 5 = 10)
Bring down 4, then bring down 5
=> 45 / 5 = 9
Thus the answer is 29, there are 29 5s in 145.
Answer:
x=7
Step-by-step explanation:
3x+1=4x-6
take the x's in one side and the normal numbers on the other side.
3x-4x= -6-1
-x= -7
the substraction signs are crossed out, therefore
ans: x=7
