Answer:
Step-by-step explanation:
We are given that
Side of square carpet,s=5 ft
1 foot=12 in
We have to find the maximum error in the area of the carpet by using the linear approximation .
Area of square,A=
Substitute the values
Hence, the maximum error in the area of the carpet=
Answer:
C
Step-by-step explanation:
The degrees of a triangle add up to 180.
Angle C is already 90 degrees therefore angle A + angle B = 90 degrees.
Angle A is equal to sinA=1/2.
sinA=1/2 is equal to 30 degrees if you press 2nd, sin (1/2) into the calculator. You may also know this if you have memorized the values of trig.
90-30=60.
That leaves you with 60 degrees for angle B.

Step-by-step explanation:
Answer:
The number of books are 189.
Step-by-step explanation:
ratio of note books to the books = 2 : 3
total notebooks = 126
Let the number of books is x.
So, the ratio is
So, the number of books are 189.
