Answer:

13 degrees

Step-by-step explanation:

Because of the alternate interior angles, I know that angle EB is also 77. Now, knowing that it's a right angle, I can subtract 77 from 90 to get 13.

Keianaka and Christopher are participating in a volunteer project painting homes for elderly people in their neighborhood. Keian

Burka [1]

The K-team can paint a whole house in 60 minutes (super fast!!!). How much of a house can the team paint in 1 minute? The K-team can paint 1/60 of a house per minute.

The C-team can paint a whole hose in 80 minutes. How much of a house can the team paint in 1 minute? The C-team can paint 1/80 of a house per minute.

Suppose both teams paint for the same amount of time -- call the time t (minutes).

Combine the work they do to paint 1 whole house:

$\frac{1}{60}t+\frac{1}{80}t=1$

Multiply all the terms by the Least Common Denominator, LCD = 240.

$240(\frac{1}{60})t+240(\frac{1}{80})t=240$

Now, can you finish it? By the way, the answer is not a whole number! Hint: it will be between 30 and 40 minutes.

The width of a rectangle measures (4.4d-4.3)(4.4d−4.3) centimeters, and its length measures (7.6d+4.7)(7.6d+4.7) centimeters. Wh

Answer:

Perimeter, P = (24d+0.8) cm

Step-by-step explanation:

Given that,

Width of rectangle, B = (4.4d−4.3) cm

Length, l = (7.6d+4.7)

Perimeter is equal to the sum of all sides. A rectangle have 4 sides. The opposite sides of a rectangle are equal. So,

Perimeter = 2(L+B)

P = 2[(7.6d+4.7)+(4.4d−4.3)]

Collecting like terms

P = 2[(7.6d+4.4d)+(4.7−4.3)]

P=2(12d+0.4)

⇒ P = 24d+0.8

So, the expression for the perimeter of the rectangle is (24d+0.8) cm.
