Answer:
The result after partial products of 89 x 38 is 3382
Step-by-step explanation:
We need to solve 89 x 38 using partial products.
In Partial products we divide each term such that 89 can be written as 80 and 9 while 38 can be written as 30 and 8
We will multiply each term with other and then find their sum.
Multiplication is shown in figure attached.
Now adding the results of each cell in the table:
2400+640+270+72= 3382
So, the result after partial products of 89 x 38 is 3382.

Answer:
adults = 40
children = 68
Step-by-step explanation:
Let the children=c
Let the adults = a
<em><u>Equations</u></em>
a + c = 108 (1)
3.75a + 1.5c = 252 (2)
Multiply (1) by 1.5
1.5a + 1.5c = 162 (3)
Subtract (3) from (2)
3.75a + 1.5c = 252
1.5 a + 1.5c = <u>162</u> Subtract
2.25a = 90 Divide by 2.25
a = 90/2.25
a = 40
<em><u>Find the number of children</u></em>
a + c = 108
40 + c = 108
c = 108 - 40
c = 68
<em><u>Check</u></em>
LHS
3.75 * 40 + 1.50 * 68
150 + 102
252 Which checks with the right hand side.
A^2 + b^2 = c^2
6^2 + b^2 = 10^2
36+b^2 = 100, then i would subtract 36 on both sides to isolate the b^2, the value we're trying to find.
b^2=-36+100
b^2 = 64, now we have to find the square root of 64...
b(x)=8
