Answer:
P = 100 centimeters (assuming you are asking for the perimeter)
Step-by-step explanation:
P = 2 (L + W) OR P = 2L + 2W where P equals the perimeter, L equals the length, and W equals the width.
Since the rectangle's length is 4 times its width and given we know the width is 10 centimeters, then the length is 40 centimeters. Now we can substitute these values in our formula, okay?
P = 2 (L + W)
P = 2 (40 + 10)
P = 80 + 20
P = 100 centimeters
The answer for this problem is 1.7 I think I’m not sure
Answer:
See explanations below
Step-by-step explanation:
a) 1/4+5/4
= (1+5)/4
= 6/4
= 3/2
b) 23/17+11/17
= (23+11)/17
= 34/17
= 2
c) 16/93+15/93
= (16+15)/93
= 31/93
= 1/3
d) 11/14+23/14
= (11+23)/14
= 34/14
= 17/7
e) 3/16+15/16
= (3+15)/16
= 18/16
= 9/8
f) 1 1/8 + 1 3/8
= 9/8 + 11/8
= (9+11)/8
= 20/8
= 5/2
g) 1 3/10+3 1/10;
= 13/10+31/10
= (13+31)/10
= 44/10
h) 2 3/5+3 2/5
= 13/5+17/5
= (13+17)/5
= 30/5
= 6
Answer:
60$ is the normal price.
Why:
Because if 45$ is 75%, then 30$ is 50%, 15 is 25%, and 0 is 0%. 50% + 50% = 100%. (That's how I did this one, anyway. This works on any 25%, 50%, or 75% problem.)
