Why?
The first thing we need to do is find the area of the triangle, we can to that by subtracting the area of ABCD from ACBE, then, we can use the formulas to calculate the area for both triangle and rectangle to find "f" and "g".
Calculating we have:
Now, we can calculate "f" by using the formula to calculate the area of the triangle:
Now, finding "g" by using the formula to calculate the area of the rectangle, we have:
Hence, we have that:
Have a nice day!
Answer: -14
Step-by-step explanation: 3-17= -14
17+(-14)=3
Answer:
D. 15P15 * 10P5
Step-by-step explanation:
Since you have to place all first-grade students in the first three rows, and nowhere else, we have to make a special calculation for that, then another for the rest of the bus.
These are permutations since the order is important. If we sit John, Paul, Ringo, George and Pete in this order in the first row it's a different way than seating them (in the same order) in the second row for example.
For the 15 first-graders of the first three rows (15 seats), we have 15P15 since all 15 places have to be occupied by all 15 first-graders.
Then we have 10 remaining seats left to be assigned to the 5 second-graders. That is 10P5.
We then multiply the permutation numbers of those two arrangements to get the total ways:
15P15 * 10P5, answer D.
Answer:
ABC
Step-by-step explanation:
Answer:
Step-by-step explanation:
The constant of proportionality is the same thing as the slope when the y intercept is 0.
y1 = 27.6
y2 = 82.8
x1 =2
x1 = 6
m = (y2 - y1)/(x2 - x1)
m = (82.8 - 27.6)/(6,2)
m = 55.2/4
m = 13.8
The constant of proportionality = 13.8
