Answer:
d, c, a, b
d= 32, 56
c = 34, 64
a = 85, 92
b = 23, 55
Step-by-step explanation:
(area of square) - (area of triangle)
We know the are of a square is equal to s^2, where s is the side length.
While the are of a right angle tringle is 1/2*base*height
Then we have,
s = 10
base = 4
height = 4
(area of square) - (area of triangle)
=> (10^2) - (1/2)(4)(4)
=> 100 - 8
=> 92
Finally we get: 92 in^2
It's D. scientific notation is in the form of n x 10^m, with n any number between 1 to 10.
61.
40 ==> 100 %
x ==> 15 %
15*40/100 = 6.
Therefore, merely 6 students received C grades.
62.
23 500 ==> 100%
x ==> 42 %
42*23500/100 = 9870
Therefore 9870 people in the town are over 45 years of age.
You continue wth this method and you'll find for the 63, 64, 65.
In maths, you have to understand what you're doing dude ^^.
Whatever the answer for 64 and 65 are
64.
21.50*20/100 = 4.3
65.
250 ==> 100 %
45 ==> x %
x = 45*100/250 = 18 %
i will let you do the 63 alone, give me what you have found in the comments, i'll verify your answer.
Hope this helps !
