Step-by-step explanation:
Multiply the amount by 0.46 and subtract from the amount.
The difference between amount and 0.46 * amount is the answer.
A) √50 = √(25 x 2) =√(5² x 2) = 5√2, what Jacklyn did is the other way round, instead of putting the perfect square out of the radical & keep the 2 inside, she inversed the sens of the operation
b) We have to find the square of the smaller & largest numbers that are near 50:
7² = 49 & 8² = 64==> so 49<50<64 & the number is between the square root of 7 & the square root of 8, but we also notice that 50 is very very near 49, hence let's try 7.1==> 7² = 7.1 x 7.1 = 50.41, which is a very good approximation. Then the approx. to √50 ≈ 50.41
25/40 = x/120
solve for x you get 75
Answer:
10.17
Step-by-step explanation:
Given the following Quadratic equation:
The steps to solve it are:
1. Substitute into the equation:
2. Use the Quadratic formula .
In this case:
Substituting values into the Quadratic equation, you get (Round the values to the nearest hundreth):
3. The positive value is the time that the rocket will hit the ground.
Therefore, the rocket will hit the ground after .
