Answer:
17.3 cm
Step-by-step explanation:
20² = 10² + x²
400 = 100 + x²
300 = x²
x = 17.3 cm
Answer:
The missing length would be 24.
First, you find the ratio of 55 to 33.
This gets you approximately 1.66666667
Multiply 36 by 1.66666667. This will get you 60.
60 - 36 = 24
The unknown value is 24.
Answer:
11
Step-by-step explanation:
If you add 11 6 times, you will get 66 or if you multiply 11 times 66 you will get 66.
Multiplication was invented to reduce the work involved in repeated addition.
... 88 + 88 + 88 + 88 = 4×88 = 352
