Answer:
Second graph shows x = - 2
Answer:
He will take 60 seconds to move from one end of the sidewalk to other.
Step-by-step explanation:
Given:
A person on a moving sidewalk,
21 feet in 7 seconds
Then 180 feet
To Find:
Total time =?
Solution:
Speed:
Speed is defined as the rate of distance covered in per unit time.
It is given as
Substituting the given values we get
Now, With this speed if he walk 180 feet then the time is
Substituting Speed and Distance we get
He will take 60 seconds to move from one end of the sidewalk to other.
Option c. is the correct answer.
When the variance should be investigated.
A variance is the difference between a result's actual value and what was anticipated or budgeted. Variances can be either positive or negative. When the actual is higher than the projected or budgeted amount, a favorable variance occurs. The variance is unfavorable when actuals fall short of the amounts allocated in the budget. A variance therefore shows whether or not the actual performance is proceeding as expected.
While,
Option a. is inaccurate. As, the cause of the variance can vary, depending on factors like changes in delivery costs, market costs, production techniques, the use of subpar materials, seasonal factors, or even a simple mistake. Therefore, additional research and subsequent actions are needed to identify the cause of the variance. The cause of a variance cannot be identified by the variance itself.
Option b. is inaccurate. A variance only shows the discrepancy between the anticipated and actual amounts. It makes no mention of who is to blame for the deviation.
Option d. is inaccurate. After variances are identified, one of the most important steps is to investigate them. When actual performances significantly deviate from anticipated outcomes, variations are typically investigated.

B. 90
Because, a circle is 360 degrees total. Angle FG is 130 degrees. Angle GD is 90 degrees. It's remaining 2 so.... 130+90=220 But every circle is 360 degrees so... 360-220=140. And ED looks similar to GD which is 90 degrees
