Answer:
12
Step-by-step explanation:
Pythagorean Theorem states that
a² + b² = c²
plug in your terms
9² + b² = 15²
81 + b² = 225
then subtract 81 from 225 to get your b²
b² = 144
then find the square root of 144
the square root is 12 because 12 x 12 = 144
Use doubling and halving to solve. So halve 12 and double 50. Then solve. 6*100=600
Answer:
1.0915 × 10
^9
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Well it should be like this tell me if im wrong, ↓
3D + 12
___ ___
3 3
so, hypo thinking once 3 is divided should leave you with . ↓
D = 4 cause once you do all the cancellations it basically leads 2 D then you have to divide →→ 12/3 → 3·4 or 4·3 either way it equals 12 sooo just do the math and you will come up with ...............................↓
-Hope this helped you any if not so comment right answer D=4 :)
