Answer:129
Step-by-step explanation:(621 x 0.25) + (750 x 0.10) = 230.25
750 - 621 = 129 more dimes than quarters
Answer:
80in²
Step-by-step explanation:
Hey There!
So the first step of this problem is to find the width of the scale drawing
To do so we need to find the scale factor
To find the scale factor we divide the length of the room by the length of the scale factor
32/8=4
so the scale factor is 4
now to find the width
40/4=10
so the width of the scale drawing is 10 in
now we can find the area given the length and the width
10x8=80in²
so we can conclude that the area of the scale drawing is 80in²
Answer: 0.023
Step-by-step explanation:
Given that:
Number of green balls = 9
Number of white balls = 8
Total number of balls = 9 + 8 = 17
Drawing with replacement :
Probability of white :
First draw = 8/17
2nd draw = 8/17
3rd draw =. 8/17
4th draw = 8/17
5th draw = 8/17
P(all 5 are white) = 8/17 * 8/17 * 8/17 * 8/17 * 8/17 = 32768/1419857
= 0.0230783
= 0.023
5/6 = .833333333333 * 100 = 83.33333333
24/6 = 4 *100 =400%
400%+83.333333% = 483.33333%
