In 30 hours he will go 25 miles and you can divide by 3 to get ten hours
25/3= 8.33333333 so on so on.
Answer:
mean =503.75
median=400
mode=400
range=691
Step-by-step explanation:
mean= 211+351+359+400+400+659+748+902=4030/8= 503.75
range= highest number -lowest number = 902-211=691
median= 400+400 =800/2= 400
Answer:
Step-by-step explanation:
When learning about commutative and associative properties, we learn that ...
a + b = b + a . . . . . addition is commutative
ab = ba . . . . . . . . . multiplication is commutative
But we also know that ...
a - b ≠ b - a . . . . . . subtraction is not commutative
a/b ≠ b/a . . . . . . . . division is not commutative
__
We also learn that ...
a + (b+c) = (a+b) +c . . . . addition is associative
a(bc) = (ab)c . . . . . multiplication is associative
And of course, ...
a - (b -c) ≠ (a -b) -c . . . . subtraction is not associative
a/(b/c) ≠ (a/b)/c . . . . . . . division is not associative
_____
However, you can use associative and commutative properties in problems involving subtraction and division if you write the expression properly:
a - (b - c) = a +(-(b -c)) = a +((-b) +c) = (a +(-b)) +c . . . . keeping the sign with the value makes it an addition problem, so the associative property can apply
(a/b)/c = (a(1/b))(1/c) = a(1/b·1/c) = writing the division as multiplication by a reciprocal makes it so the associative property can apply
Option D
The trip lasts for 
<em><u>Solution:</u></em>
<em><u>Mr Patel is planning to drive 325 miles</u></em>
Average speed is 65 mph
He will stop one hour for lunch and take a 15 min rest break
Let us first find the time taken
Thus he covers 325 miles in 5 hours
Also, given that, he will stop one hour for lunch and take a 15 min rest break
<em><u>Therefore, total time taken for trip is:</u></em>
Total time = 5 hours + 1 hour + 15 minutes
Total time = 6 hours 15 minutes
We know that,
1 hour = 60 minutes
Therefore,
Thus the trip lasts for
Answer:
2
/3 (decimal form ≅ 0.6666667 )
Step-by-step explanation:
Unary minus: -1
/4
= -1
/4
Unary minus: -3
/8
= -3
/8
Divide: the result of step No. 1 : the result of step No. 2 = -1
/4
: (-3
/8
) =
-1
/4 x -8
/3 = -1 (-8) divided by 4(3) = 8
/12 = 4(2
) divided by 4(3) = 2
/3
