Answer:
fgi = 48
fgh = 24
hgi = 24
Step-by-step explanation:
Bisection divides an angle into two equal angles,
So,
4x - 20 = 3x - 9
4x - 3x = - 9 + 20
x = 11
fgi = 3x - 9 + 4x - 20
= 3x + 4x - 20 - 9
= 7x - 29
= 7 ( 11 ) - 29
= 77 - 29
fgi = 48
fgh = 3x - 9
= 3 ( 11 ) - 9
= 33 - 9
fgh = 24
hgi = 4x - 20
= 4 ( 11 ) - 20
= 44 - 20
hgi = 24
Answer:
They swam 15 days
Step-by-step explanation:
Divide 48 by 3.2
It is quadratic, because the highest degree for x is 2, x². Expand the expression and you'll see: f(x)=3x²-3x-3x-7
simplify: f(x)=3x²-6x-7
the quadratic term is 3x², the linear term is -6x, the constant is -7
80 would be your answer for this question
First, let me do the Mathematical part of that, and then I shall explain the theory behind it.
Mathematical part:
We are going to multiply 513 with 46. So the two partial products that we are going to choose are 40 and 6.
Multiply 513 with 6 first.
513
x46
--------------------------
18 (as 6*3 = 18)
60 (as 6*10 = 60; In 513, the digit at tenths place is 1, so 1*10=10)
3000 (as 6*500 = 3000; In 513, 5 is at hundredth place, so 5*100=500)
120 (as 40*3 = 120; since 4 is at the tenth place, so 4*10=40)
400 (as 40*10 = 400)
20000 (as 40*500 = 20000)
--------------------------
23598 (Add all of them)
Theory:
As you can see above that we have chosen the two partial products individually which are 6 and 40. Since 4 in 46 is in tenth place, we have to consider it 40 (since 4*10 = 40). One by one, we first multiply 6 with 513. Then we move to the tenth place, and multiply 513 with 40. At the end, we have added all the results we found after multiplication.
Check: If we check the multiplication result by using the calculator, we would get the same result (23598).
Another Method (instant):
513 * (40+6) = (513*40) + (513*6) = 23598.
