Answer:
The statement that is true is:
A debt of $17 is a larger value than a debt of $20.
Step-by-step explanation:
Let us look at the statements one after the other to determine if they are true or not:
1) A debt of $17 is a larger value than a debt of $20: This is true because when measuring debts, we will consider the values in the negative sense (-). Therefore, a debt of $17 has a value of (-17) and a debt of $20 has a value of (-20). -17 is larger than - 20 on a number line, hence, a debt of $17 has a larger value for the debtor, than a debt of 20$
2) One half an apple is equivalent to 8 fourths apples:
one half an apple =
8 fourths of an apple = . Therefore, one half of an apple is not equivalent to 8 fourth of an apple.
3) 8.01 is a smaller increase in sales than 8.001: This statement is false because 8.001 is counted before 8.01, and the difference between 8.01 and 8.001 is:
8.01 - 8.001 = +0.009, hence, 8.01 is larger than 8.01 by a magnitude of 0.009
4) is a lower temperature than 6 below zero:
6 below zero = - 6°
On the number line, -6 is smaller than hence the statement is false.
Answer:
The speed of wind is 32 mile per hour
The speed of plane is 210 mile per hour
Step-by-step explanation:
Given as :
The speed of plane with tailwind = 242 mph
The speed of the return trip = 178 mph
Let The speed of the wind = y mph
The speed of the plane = x mph
Now , According to question
The speed of plane with tailwind = x + y
Or, x + y = 242 mph .......1
and The speed of the return trip = 178 mph
or , x - y = 178 mph ........2
Solving both equations
( x + y ) + ( x - y ) = 242 + 178
Or, 2 x = 420
∴ x =
I.e x = 210 mph
Put the value of x in eq 1
I.e x + y = 242 mph
or, 210 + y = 242
∴ y = 242 - 210
I.e y = 32 mph
Hence The speed of wind is 32 mile per hour
And The speed of plane is 210 mile per hour Answer
