Answer:
Women: 448 Men: 560 Children: 1232
Step-by-step explanation:
5+4+11 = 20/2240 = 112
Women = 4 x 112 = 448
Men = 5 x 112 = 560
Children = 11 x 112 = 1232
Total = 1232 + 560 +448 = 2240
Answer:
Actual length of w is 0.075 units.
Step-by-step explanation:
Given the actual length of side t is 0.045 cm.
we have to use the scale drawing to find the actual side length of w.
As given the actual length of t is 0.045 cm.
Hence, we can find the scale factor using the lengths of t i.e actual length and after scale drawing by dividing.
Scale factor is
Hence, we get the scale factor.
Now,
⇒
⇒ Actual length of w is
Option B is correct.
This is a ratio problem. First, we need to add the number of students polled.
7 + 4 + 3 + 6 = 20
Next, look at how many out of 20 students selected Science.
3 out of 20.
Say it this way:
3 is to 20 as ? is to 400.
Express it this way:
3/20 = x/400
Cross multiply to eliminate the denominators.
3 x 400 = 20 x Now solve for x.
1200 = 20 x
x = 60
Check it!
Does 60/400 reduce to 3/20? Yes!
60 students are predicted to select science out of 400
I think your posting problem your missing an x after 28.
Therefore your answer is
C. (2x+7)(2x+7)
To check use distributive
2x(2x)+2x(7)+7(2x)+7(7)
4x^2+14x+14x+49
4x^2+28x+49
