Answer:
This distance would be <u>14 cm</u> long.
Step-by-step explanation:
2 cm = 35 km
1 cm = 35/2 = 17.5 km
Let's assume: x -> the distance on a map (in cm)
so:
x * 17.5 = 245
x = 245/17.5 = 14 (cm)
Answer:
Your answers are C and D
Step-by-step explanation:
If you pay attention to the chart you will notice that medium duty fabric can last from 9000 to 15000 rubs meaning that since fabric B lasted 9200 it would be a medium duty fabric, making Fabric A light duty fabric.
A: This is INCORRECT because fabric B is medium duty
B: This is INCORRECT because Fabric B lasted longer than Fabric A
C: This is CORRECT because Fabric B is medium duty fabric
D:This is CORRECT because Fabric B lasted more rubs than Fabric A because its a more durable fabric
E: This is INCORRECT because Fabric A does not meet the requirements to be a Medium duty fabric.

I not know what a sample variance or a standard deviation is.
Answer:
109°
Step-by-step explanation:
X = 38+ (180-38)/2
= 38 + (142/2)
= 38 + 71
= 109°
First = x^2
Inner = -5x
Outer = +8x
Last = -40
It is correct!
