Add 1/(x-8) to both sides
cross multiply or multply both sides by (5-x)(x-8)
5(x-8)=5-x
distribute
5x-40=4-x
minus x from both sides
4x-40=4
add 40 to both sides
4x=44
divide by 4
x=11
Answer:
About 316.13
Step-by-step explanation:
We know:
Diameter (d) = <u>11</u> (of the circle)
Area of the circle: pi(11)^2 = <u>121pi </u>
Side of the square = <u>8 </u>
so area of the square is 8^2 = <u>64</u>
Area of the shaded region:
121pi-64 =316.13
hope this helped
B) since 1950 is between 1281 and 2796 add the two valves together and then divide them by two
Not sure of A so ..
Answer: A 4 side dice.
Step-by-step explanation:
Benjamin has 4 possible homerooms with the same probability. This means that every homeroom has a 1/4 = 0.25 (or 25%) probability of getting chosen.
You could emulate this situation with a 4 sided dice (are like little pyramids) where each side of the dice would represent the selection of one of the homerooms.
Hey there! Direct variation, a concept commonly applied to linear equations.
The constant of variation is a concept which simply refers to the change in y, based on the change in x. If this change is constant, then it is a constant of variation.
You can find the constant of variation (usually referred to as 'k') by dividing any point's y-value by its x-value.
In this instance, we have the point (3.5, 14)
14 / 3.5 = 4
The constant of variation for this equation would be 4.
