Step-by-step explanation:
Option D is the correct answer
Because if the blouse is of 8 dollars then 4 blouses = 32 and skirt = 12 so 3 skirts = 36
36 + 32 = 68
Susan bought 6 blouses = 8 x 6 = 48
3 skirts = 12 x 3 = 36
48 + 36 = 84
We have to find the" ratio of the area of sector ABC to the area of sector DBE".
Now,
the general formula for the area of sector is
Area of sector= 1/2 r²θ
where r is the radius and θ is the central angle in radian.
180°= π rad
1° = π/180 rad
For sector ABC, area= 1/2 (2r)²(β°)
= 1/2 *4r²*(π/180 β)
= 2r²(π/180 β)
For sector DBE, area= 1/2 (r)²(3β°)
= 1/2 *r²*3(π/180 β)
= 3/2 r²(π/180 β)
Now ratio,
Area of sector ABC/Area of sector DBE =
= 4/3
You got 2 types of data $ and %!
Line them up accordingly and cross multiply.
16% is to $38 as
100% is to $x
X= 38•100/16= $237.5 the price before discount
Answer:
14 minutes
Step-by-step explanation:
given,
given,
Betsy time taken to read one page = 1.5 minutes
Number of pages in the Betsy book = 116 pages
number of pages in Raymond Book = 94 pages
time taken by the Raymond to read = 11.38 - 8.30
= 3.08 hrs
time taken by Raymond = 188 minutes
time taken by Betsy to read book = 1.5 x 116
= 174 minutes
Raymond take more time than Betsy by = 188 - 174
= 14 minutes
Raymond take 14 minute more than Betsy
