Explanation:
Let's find the slope of the table. This will tell us the rate of change.
m = slope
m = (y2-y1)/(x2-x1)
m = (25250 - 26375)/(2 - 1) .... I used the first two rows
m = -1125/1
m = -1125
The slope of -1125 means the plane's altitude is decreasing at a rate of 1125 feet per minute. This is the descent speed.
Since we're told the initial altitude was 27500 ft, this means b = 27500
This means y = mx+b turns into y = -1125x+27500
x is the number of minutes and y is the altitude at time x
As a way to check this, plug in various x values of the table. You should get corresponding y values that match the table. I'll let you do this part.
------------------
Now plug in y = 16250 and solve for x
y = -1125x+27500
16250 = -1125x+27500
-1125x+27500 = 16250
-1125x = 16250-27500
-1125x = -11250
x = -11250/(-1125)
x = 10
It takes 10 minutes after the descent period has started, for the pilot to get to 16,250 ft.
Since the pilot was contacted at the x = 4 minute mark, this means 10-4 = 6 minutes is the duration needed for the pilot to go from 23,000 ft to 16,250 ft.
Answer:
FALSE
Step-by-step explanation:
To Find: True or False
If any two sides and any angle are congruent in two triangles, then the triangles must be congruent.
It is not always true according to rule of congruence. If two sides are equal then angle between them must be equal for SAS property.
It is false
Total possible congruence for two sides and one angle : SSA , A-SS, SAS
Only three possible property.
SAS is only true for concurrency of triangle.
SSA and A-SS are false for any two side and any one angle.
Please find the attachment for difference in three property.
Hence, The given statement is false.
1 5/6 x 2
22/6 is the result of the product of the expression.
To rewrite the multiplication problem using improper fractions, we need to convert the mixed number 1 5/6 to an improper fraction.
1 5/6 = 11/6
Now, the multiplication problem can be expressed as:
1 5/6 x 2= 11/6 x 2
1 5/6 x 2 = 22/6
Therefore, the multiplication problem, using improper fractions, is 22/6

The expected value of the payment is $5
When two quantities have some dependence in their values they can be said proportional to each other.
It can be of two types such as direct and indirect.
The direct proportionality means the values of both the quantities are increasing or decreasing at the same time while the indirect proportionality implies value of one quantity is increasing while the other is decreasing.
Given that,
The rent for 5 DVDs for 5 nights is $5.
In order to find the rent for 1 night for 1 DVD, direct and indirect proportion method can be used as follows,
5 DVD for 5 night costs $5.
Then, 5 DVDs for 1 night costs 5 × 5 = $25.
And, 1 DVD for 1 night costs 25/5 = $5.
Hence, the cost of 1 DVD for 1 night is $5.
