Step-by-step explanation:
secants originating from the same point have the same relative length relationship :
outside part × sum of outside and inside parts
is the same for every secant from the same point.
so,
5×(7+5) = 6×(2x-8+6) = 12x - 12
60 = 12x - 12
12x = 72
x = 6
WV = 2x - 8 = 2×6 - 8 = 12 - 8 = 4
so, B is correct.
Answer:
Area of a triangle = bh/2
Area of a rectangle = bh
The area of the triangles are the same, the area of the rectangles are the same.
triangle: 9x8/2
72/2 = 36
Rectangle: 8x14=112
There are 2 triangles and 3 rectangles so,
2(36)+3(112)
72+336= 408 in²
Q17:
one week = $560
52 weeks = 560 x 52 = $29120
Q18:
one year = $28500
52 weeks = 28500
1 week = 28500 ÷ 52 = $548
Q19:
5% of $300000 = 0.05 x 300000 = $15000
$15000 + $12000 = $27000
2p+6a=$14
3p+9a=$21
3p+9a=21
Subtract 9a
3p=21-9a
divide all by 3
p=7-3a
plug it into start equations
2p+6a=14
2(7-3a)+6a=14
14-6a....+6a=14
this zeroes out...
Answer:
1
Step-by-step explanation:
Set the height of the bar to 1 because there is only 1 number between 40-49 i.e. 49
