I need help on number 12

Mathematics

Angle ACD and angle CAD are angles that add to 90 degrees (60+30 = 90) and they are non-adjacent. They do not share a common vertex. So this is why the two angles fit the description for number 12.

In contrast, two adjacent complementary angles are angle FDG and angle GDE. They add to 90 degrees and share the common vertex point D. They also share a common segment DG.

Tyrone claims that the first step to simplify this expression
ser-zykov [4K]

Answer:

1/(m^4*n^2

Step-by-step explanation:

The given expression is

(m^2*n^-3)/(m^6*n^-1)

Tyrone's approach.

Raising the expression to the 3rd power will not help. It will make the expression more complicated.

Alisha's approach.

(m^2*n^-2)/(m^6*n^-1)

= m^(2-6)*n^(-3+1)

= m^-4*n^-2

= 1/(m^4*n^2)

Alisha's approach will simplify the expression to 1/(m^4*n^2

The length of a rectangle is seven more than double the width. If the perimeter is 22 inches find the dimensions
lubasha [3.4K]

Answer:

width = 1 1/3 inches

length = 9 2/3 inches

Step-by-step explanation:

let 'w' = width

let '7+2w' = length

P = 2l + 2w

22 = 2w + 2(7+2w)

22 = 2w + 14 + 4w

8 = 6w

w = 4/3 or 1 1/3

substitute 1 1/3, or 4/3, to find length:

l = 7 + 2(4/3)

l = 7 + 8/3 or 9 2/3

Mila [183]

We want to find the number of dollars Chi makes for every hour he cuts lawns. This proportion would be dollars/hour.

329.12 / 34 = 9.68

Chi's hourly wage is $9.68 per hour.

Hope this helps!! :)
