Answer:
Step-by-step explanation:
The area of a square can be calculated with the following formula:
Where "s" is the side lenght of the square.
In this case, according to the data given in the exercise, the side lenght of the square playing bored is the following:
Therefore, you must substitute this value into the formula and then evaluate, in order to calculate the area of the square playing bored.
Then, you get that its area is:
The solution for v-9v+49=-2(v-7) is or 5.83(decimal form)
<u>Solution:</u>
Solving right hand side: multiply -2 with terms inside the bracket
v - 9v + 49 = -2v + 14
Move the terms from right hand side to left hand side. On moving a negative signed number from RHS to LHS, it becomes positive signed number.
Similarly, moving positive signed number from RHS to LHS, it becomes negative signed number.
v - 9v + 49 + 2v - 14 = 0
v -9v + 2v + 49 - 14 = 0
-8v + 2v + 49 - 14 = 0
-6v + 35 = 0
-6v = -35
Negative sign on numerator and denominator cancels each other
v = 5.83
Convert to a decimal which would be 0.55 (11/20).
Then you want to multiply 0.55 by 100 (which is a whole number, all % is going to come from 100) to convert to a full % -> 0.55*100
Then you will simplify 0.55*100
You answer will be 55%.
Answer:
y - 2x = 3
Step-by-step explanation:
Use the point-slope formula y - k = m(x - h), with h = 0, k = 3 and m = 2:
y - 3 = 2(x - 0), or
y - 3 = 2x, or
y - 2x = 3
Note that the given point, (0, 3), is the y-intercept of this line, and so we immediately know b in y = mx + b: it is 3.
Answer:
Or, 1/2.
Step-by-step explanation:
To find the slope of a line that crosses any two given points, we can use the slope formula:
Where (x₁, y₁) is our first point, and (x₂, y₂) is our second point.
We will let (6, -7) be our first point (x₁, y₁), and (4, -8) be our second point (x₂, y₂).
Substitute them into the formula. Hence:
Simplify:
Evaluate. Hence, our slope is:
