Answer:

7.

I) must be true

II) 1 - 1 < 2 - 4 --> false

III) (-10)*(-10) < 1*1 --> false

IV) 1/2 < 2/10 --> false

So (B) 1 must be true

8.

x!·(x + 1)!/2 = (x + 1)!^2 / (2·(x + 1)) = (17 + 1)!^2 / (2·(17 + 1)) = 18!^2 / 6^2

(D)

9.

2·√3·6 = √((2·√3)^2 + 6^2)·h --> h = 3 --> (C)

A point in the figure is selected at random. Find the probability that the point will be in the part that is not shaded
Mariulka [41]
I believe the answer is 25% or C). If you flip the half circles around then you get a full circle. When you look at the corners it is about 25%

The perimeter of a triangle is 60cm,and the ratio of the measures of the side is 2:6:7. find the measures of each side?
Nitella [24]
Hey!

Perimeter=60cm

Let sides be 'x'

Side 1=2x
Side 2=6x
Side 3=7x


Permiter of a triangle= s1+s2+s3 (sum of all sides)

60=2x+6x+7x
60=15x
60/15=x
x=4

Side 1= 2×4=8cm
Side 2=6×4=24cm
Side 3=7×4=28cm

Hope it helps...!!!
