Answer:

c. 135 hr

Step-by-step explanation:

The following method of converting units is called "dimensional analysis."

Write every conversion factor as a fraction. Each conversion factor fraction equals 1, so it changes units but not the value. In the end, all the undesired units cancel out leaving the desired units. Multiply the given amount by the necessary conversion factors until you arrive at the desired units.

3~extra~bagal \times \dfrac{10~sobrang~bagal}{1~extra~bagal} \times \dfrac{3~bagal}{1~sobrang~bagal} \times \dfrac{90~min}{1~bagal} \times \dfrac{1~hr}{60~min} =

= 135~hr}

What is the measure of DE?
tatuchka [14]

Answer:

Step-by-step explanation:

Alright, lets get started.

The two chords are intersection each other at point B.

DBE=ABC

Both are opposite angles that is 39 degrees.

Angle ABC forms the arc AC which is given 41 degree.

The arc DE will be same length as arc AC because angle ABC and angle DBE are same that is 39 degrees.

So, arc DE = 41

So, the answer is DE = 41 degrees ....   Answer : option D

Hope it will help :)

You are graphing y < 2x + 1. What type of line do you use and where do you shade?
bazaltina [42]
Since there isn't a line under the < sign, this means that we used a dotted or dashed line. The dotted or dashed line indicates that we do NOT include the boundary as part of the solution set. 

Since y is isolated and we have a less than sign, this means we shade below the dashed/dotted boundary line. Specifically, the boundary line is the graph of y = 2x+1. This boundary line goes through (0,1) and (1,3). Again, points on this boundary line are NOT part of the solution set. 

So in summary we have:
A dashed or dotted boundary line
The shaded region is below the dashed/dotted boundary line.

Solve the system of linear equations using either substitution or the elimination method.
lara31 [8.8K]

Answer:

x = -1

y = 2

Step-by-step explanation:

x + y = 1

y = -x + 1

y = -x + 1  (Multiply this by -1)

y = 3x +5

-y = x - 1

y = 3x +5

0 = 4x + 4

4x = -4

x = -1

x + y = 1

-1 + y = 1

y = 2
