Answer:
4
Step-by-step explanation:
A simple matter of using Pythagoras. The hypotenuse is the ladder, and one of the legs is the wall, and we have to figure out the value of the other leg.
The Pythagorean formuda is (hypotenuse = a): a² + b² = c² (b and c are the other sides)
applying the values: a = 5 and b or c is 3 (I'll put b = 3)
5² = 3² + c²
25 = 9 + c²
25 - 9 = c²
16 = c²
√16 = c
4 = c
c = 4
Answer:
1/35
Step-by-step explanation:
1/3 of 10 (of means multiply)
1/3 times 10 is 10/3
1/7 of 8/12=2/21
2/21 divided by 10/3
use keep change flip
2/21 divided by 10/3 equals 2/21* 3/10
1/35 is the answer
The answer is 1224. You do 70.5 + 65.5, divided by two, then you take that answer and multiply by 18 to get 1224
We can simplify across between the 5 and the 50 and also between the 42 and the 3.
