Let's first convert Lancy's height into inches, since it includes feet.
There are 12 inches in a foot, so let's multiply 4 by 12.
4×12=48; Add 8 inches since she is 4 feet 8 inches.
48+8= 56
She is 56 inches tall. We need to find the amount of centimeters she is in height. We can do the same thing by multiplying 56 by 2.54.
56×2.54= 142.24
She is 142.24 centimeters tall.
Answer:
4 : 1
Step-by-step explanation:
(3 days : 18 hours) this is a ratio , where both the units must be same before simplifying.
1 day = 24 hours, 3 days = (3 × 24) hours
3 days = 72 hours
Now both the units are same, so we can easily simplify now.
72 hours : 18 hours
36 : 9 = 12 : 3
= 4 : 1 ( Answer)
Answer:
b=4 x A
Step-by-step explanation:
The Pythagorean theorem tells you that for legs a and b, and hypotenuse c this relationship holds:
c² = a² + b²
It can be useful to make a couple of rearrangements of this relation.
c = √(a² +b²)
a = √(c² -b²)
1. c = √(10² + 8²) = √164 = 2√41
2. a = √(26² - 10²) = √576 = 24
_____
It doesn't matter which leg you call "a" and which one you call "b", unless they are specifically marked on the triangle. Then use the marks you are given.
