Answer:
6 units squared
Step-by-step explanation:
To solve this problem you can solve for the entire area of the square and subtract the area of the unfilled areas for the area of the shaded region..
Area of entire square is 4*4=16
Now for the sections that are unfilled:
4*3/2= 6
1*1/2= 0.5
2*1 = 2
1*1 = 0.5
2*1/2 = 1
Total area of Unfilled region = 6 + 0.5 + 2 + 0.5 +1 = 10
Area of filled region = 16 - 10 = 6 units squared
Hope this helped!
Answer:
Find the value of x, if 8,x, x, 50 are in proportion.
If a,b,c and d are in proportion then we have a/b = c/d
Now we need to find the value of x given if 8, x, x, 50 are in proportion.
So we have 8/x = x/50
Or x x x = 8 x 50
Or x^2 = 400
Or x = ±√400
Or x = ± 20
Therefore the value of x will be + 20 or - 20
Step-by-step explanation:
We have -4(x - 6) + 3(a - 7) = -4x + 24 + 3a - 21 = -4a + 3a + 3
so the answer is B
ok done. Thank to me :>
Answer:
10
Step-by-step explanation:
If W is the present age of the woman and D is the present age of the daughter, then:
W = 4D
W + 5 = 3(D + 5)
Substituting the first equation into the second:
4D + 5 = 3(D + 5)
4D + 5 = 3D + 15
D = 10
The daughter is 10 years old.
