Answer:
20.2 miles
Step-by-step explanation:
This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:
= 
+ 
= 
+ 
576 = 
+ 169
= 576 - 169
= 407
x = 
= 20.1742
x = 20.2 miles
The glider has to fly 20.2 miles to return to the airport.
Answer: The correct answer is option A: 6
Step-by-step explanation: We shall start by splitting the word problem into bits to ease our calculations.
We start with “the quotient of a and 6...” and that can be expressed as
a/6 where a equals 186, this becomes
186/6 and this equals 31.
Note that quotient means the result derived from dividing two numbers/values.
Next, “The difference of ... and b squared”
The missing part of this statement has been calculated as 31, so this can now be written as “The difference of 31 and b squared” where b equals 5 and b squared now equals 25. Hence what we have is the difference of 31 and 25
That is, 31 - 25 and that equals 6.
Therefore, the expression can now be written out as;
(a/6) - b^2
When a equals 186 and b equals 5, the answer is 6
Answer:
(2.4)(-1.8) and (0.6)(-0.4)
Step-by-step explanation:
The product of two negative numbers = a positive number. (negative × negative = positive).
Product of two positive numbers = a positive number. (Positive × positive = positive)
Product of a negative number and a positive number = a negative number. (Negative × positive = negative).
Therefore, the answer choice that shows two products that both will result in negative values would be the answer choice that has a negative number multiplying a positive number.
Option 3 has two products in which each has a negative and positive number. That is (2.4)(-1.8) = a negative value, and
(0.6)(-0.4) = a negative value.
Therefore, the answer is Option 3: (2.4)(-1.8) and (0.6)(-0.4)
