45 1/4-> 45.25 * .5 = 22.625 = 22 5/8
gusset plate :
5 3/4 -> 5.75 * .5 = 2.875 = 2 7/8
3 1/2 -> 3.5 * .5 = 1.75 = 1 3/4
47 1/4 -> 47.25 * .5 = 23.625 = 23 5/8
2 * .5 = 1
Answer: D (5/2, -17/4)
Step-by-step explanation: Using elimination your goal is to get rid or 1 variable so you can solve for the one that's left. By adding the -2y and 2y you will get 0. You will also add the 3x+x (4x) and -1+11 (10). You have now gotten rid of the y and have 4x=10. By dividing each side by 4 we now know x =2.5. D is the only possible solution with x=2.5 (5/2) but to solve for y you plug 2.5 in to an equation as x so) x-2y=11
2.5-2y=11
-2y=8.5 Answer D (5/2,-17/4) y=-17/4 (4.25)
Answer:
Option D, 12
Step-by-step explanation:
4x-8=80/2
or, 4x-8=40
or, 4x=48
or, x=12
I think 2,3,4 or B,C,D would be correct.
The area of a triangle is (b•h)/2
And the area of a rectangle and parallelogram would just be b•h
1) 8(6) = 48/2 =24
2) 9(10 2/3) = 96/2 =48
3) 19.2(2.5) = 48
4) 16(3) = 48
Hope this is right and hope it helps. Have a good day
The percentage of births that occurred among women between the ages of 40 and 42 is 26.41%
<h3>Calculations and Parameters</h3>
First, we would add up the ages of the mothers
27 +98+239+326+389+436+468+490+460+387+286+180+102+48+19+5+1
= 3961
Thus, to find the percentage of births occurring among women between the ages of 40 and 42 was:
102+48=150
3961/150= 26.41%
