The actual square root of 2 is 1.414213562373.
I would estimate to 1.4
For the first one (aka 7) you would write 10² wich is the same as 10×10 and so the answer is 100
For the second one (aka 8) you would write 3×3×3×3×3×3×3×3×3 and the answer is 486 square miles
Answer:
Base: , Height:
Step-by-step explanation:
Let the base be . Then the height is .
By the area of a triangle theorem, we have that .
Multiplying by and expanding gives , so . We see that this quadratic factors into . Because the base is a side length and must be positive, we have that the base is .
The height is then .
C. 6/5 * 4
6/5 = 1.20 where .20 represents the 20% increase in serving.
1.20 * 4 = 4.8 is the total cups of flour needed to increase serving by 20%
4 is the 100% ; the desired increase is 20%; therefore: 100% + 20% = 120% based on 4 cups. So, 120% ÷ 100% = 1.2 * 4 = 4.80 cups
