Okay so changing from 6 inches to 5 feet is a 1:10 ratio (since 5 (feet) x 12 (inches) = 60 (inches) this gives you a 6 (original inches): 60 (inches after enlarging) ratio, which is simplified to 1:10 when you simplify both sides by a factor of 6.
So, let’s plug the 3 feet into this ratio. 3 feet is equal to 36 inches. This gives you 3.6 inches. (Since 3.6 times 10 is 36)
Hope this helps!!
Answer:
The answer to question 3 is : 2x^2 + 5x + 3
Step-by-step explanation:
The FOIL method is multiplying the first variables, the outside variables, the inside variables and the last variables.
(2x + 3)(x + 1)
F = 2x times x = 2x^2
O = 2x times 1 = 2x
I = 3 times x = 3x
L = 3 times 1 = 3
2x^2 + 5x + 3
I'll leave the rest to you. You got this!
I am pretty sure the quartile is just the third number in a data set so it would 39? I do not recommend using this I am only 14 after all <span />
Answer:
The correct answer is 12.8 J.
Step-by-step explanation:
To solve this problem, we must remember how to calculate the kinetic energy of an object.
The kinetic energy is represented by the formula K = 1/2 * m * v^2, where m represents the mass of the object and v represents the speed or velocity of the object. If we plug in the given values into the formula, we get:
K = 1/2 * m * v^2
K = (1/2) * (0.40) * (8.0)^2
Our first step is to square the velocity. After doing this step, we get the following:
K = (1/2) * (0.40) * (64)
Finally, we can perform the multiplication, to get:
K = 12.8
The unit for kinetic energy is joules, so the correct answer is 12.8 J.
Hope this helps!
