Answer: it will take them 2.22 hours working together.
Step-by-step explanation:
It takes Destiny y 4 hours to file all the daily paperwork. This means that unit rate of Destiny would be
1/4 per hour.
It takes Susan 5 hours to file the same paperwork. This means that unit rate of Susan would be
1/5 per hour.
If they work together, they would work at their own individual rates. This means that their individual rates are additive.
Let t represent the time it will take them if they worked together. Since their combined rate is additive Therefore,
1/4 + 1/5 = 1/t
9/20 = 1/t
t = 20/9 = 2.22 hours
Answer:
Anna's walk as a vector representation is
and refer attachment.
Step-by-step explanation:
Let the origin be the point 1 from where Ann start walking.
Ann walks 80 meters on a straight line 33° north of the east starting at point 1 as shown in figure below,
Resolving into the vectors, the vertical component will be 80Sin33° and Horizontal component will be 80Cos33° as shown in figure (2)
Ann walk as a vector representation is 
Thus, Anna's walk as a vector representation is 
Answer: The answer is 
Step-by-step explanation: Given that the area of the whole circle is represented by the expression

We are to find the area of the outer ring of the circle, i.e., to find the circumference of the circle.
Now, if 'r' represents the radius of the circle, then we have

Thus, the area of the outer ring is

Draw the DE ray away from the BAC angle is the next step to copy the BAC angle
<h3>Further explanation
</h3>
Angles can be formed from two ray lines that have the same starting point
Commonly used terms include foot angle, corner point, and angle size
The magnitude of the angle is usually expressed in degrees
Naming angles can be with one letter according to the vertex or with three letters with the vertex placed between two other letters
There are several steps used to copy the BAC angle:
- 2. Draw a circle using the circle tool with center A. The circle will intersect the lines BA and BC at points F and G
- 3. Use the segment tool to create a segment from the circle radius that has been created
- 4. Use the Compass tool and select the segment from the AG radius
- 5. Make a circle with center point D, with the same radius as AG
- 6. Mark the intersection of the circle with the intersection of the DE as H
- 7. Create the FG segment, and use the compass tool to select the FG segment
- 8. Create a circle with center H, which will intersect the circle with center D earlier at the point I
Then the BAC is congruent to the HDI

Answer:
It's false.... correct is a2+2ab+b2
Step-by-step explanation:
This cannot be factored anymore although. when we try to substitute a with 5 and b with 2, the answer in the right hand side of the equation is -9.
That's why it's false.
