Answer:
40 miles per hour
Step-by-step explanation:
Given that:
Distance = 400 miles
Without tailwind :
Time taken = 2.5 hours
Speed = distance / time
Speed = 400 miles / 2. 5
Speed = 160 miles per hour
With tail wind :
Time taken = 2 hours
Net speed = 160 + x
X. = speed of tail wind
Distance = speed * time
400 = (160 + x) * 2
400 = 320 + 2x
400 - 320 = 2x
80 = 2x
x = 40
Speed of tailwind = 40 miles per hour.
Answer: 38
Step-by-step explanation:
Since the polygons are similar, the corresponding sides are all in the same proportions.
x-2/4.5 = 16/2 = 48/6
<u>Solving for x</u>






Therefore, the value of x is 38
Answer:
Part B: is -60 divided by -10
Part C: is The number of increments is positive.
Part D: is -1 times 60 / -1 times 10
Part E: is Any number divided by itself is 1. In the expression -1 times 60, the -1s in the numerator and the denominator cancel each other out to give the result 60/10, or 6
Part F: is There are 6 increments of -10 feet in -60 feet.
Part G is: copy and paste -10 feet 6 times
Part H: is -60 / 4 increments
Part I: is there is one negative number in the expression, so the solution will be negative. There isn't a -1 in the denominator to cancel out the -1 in the numerator.
Part J: is -60 /4 =-15 Alex’s elevation change in each increment was -15 feet.
Step-by-Step Explaination: I did the test.
Answer :
★<u>Range</u> : Range is the difference of the largest value and the lowest value given in graph in STATICS.
<u>More</u> <u>information</u> :
The formula to find RANGE is :
Range = Maximum value — Minimum value
What is the use of Range :
Range gives us the idea(rough) of the outcome.
<h3>Example
:</h3>
Given :
(3,5,12,67,87,13)
Here we can see that the largest value is 87
And the lowest value is 3
Thus,the Range here is ,
= 87 — 3
= 84

Answer:
(A)
Step-by-step explanation:
The given equation is :

=
We need to simplify the given equation, so
Using the identity,
, we have
=x^{2}+2xy+y^{2}[/tex]
Which is the required simplified form of the given equation.
Hence, option A is correct.
