Answer: 7.7%
Step-by-step explanation: First find the increase in height by subtracting 52 from 56. 56-52=4.
To find what percent this is of 52, divide 4 by 52. 4/52=0.0769. Then convert this from a decimal to a percent by multiplying by 100. 0.0769*100=7.69.
I just rounded it to the nearest tenth, you can change it how you need to.
Answer:
The shortest total length of fence with which this can be done is 40m^2
Step-by-step explanation:
Lets say that your area has width and length . Since you want to divided it into 3 equal areas by fences there would be 4 lengths and the area and perimeter would be given by the following equations.
Perimeter =
We want to optimize the perimeter so
Solving for we get
Since and then
Let S represent the cost of use of Silver Gym for a month.
Let F represent the cost of use of Fit Factor for a month.
Let T represent the number of training sessions used in the month.
S = 45 +25T
F = 75 +15T
We want to find T so the costs are equal.
.. S = F
.. 45 +25T = 75 +15T
.. 10T = 30 . . . . . . . . . subtract 45+15T
.. T = 3 . . . . . . . . . . . . divide by 10
Sarah would have to buy 3 training sessions to make the cost at the two gyms equal.

<em><u> You are looking for 2 numbers that multiply to give 6 and that either add or subtract to give 5. Well, the following numbers multiply to give 6. 1 * 6. 2 * 3. These are the only whole numbers that can multiply to make 6 (x + 2)(x - 3) = x^2 - x - 6 so this dosen't work. Lets try (x + 1)(x - 6) = x^2 - 5x - 6</u></em></h2>

Answer:
-0.8 and -8.2
Step-by-step explanation:
To solve a quadratic you first need to have one side of the equation equal to zero (because x-intercepts are when y is zero).
4x^2 + 24x + 13 = 2x^2 + 6x
2x^2 + 18x + 13 = 0
Then you can use the quadratic formula to solve for x. You will then come to
-18 ± sqrt(220) / 4
This will simplify out (rounding to the nearest tenth) to -0.8 and -8.2
