Answer:
It will be less than 2 hours because in total that would be an hour and 30 minutes.
Step-by-step explanation:
We know it takes 18 minutes for him to walk to school, and we also know there is 5 days of a school week, so 18x5= 90 minutes, which equals to an hour and 30 minutes, less than 2 hours in one week.
Answer:

Step-by-step explanation:
Given

Required
Find m

By comparison:

Add 3 to both sides


20% of 90 is 18
Explanation - 90 divided my 20 = 4.5 times 4 because 20 is 1/4 of 100
I think , in my opinion it’s is the middle I’m not that sure but if u can try then good luck
Answer:
Perimeter of rectangle = 6√10 units (the attachment isnt clear. It seems the answer is in option B)
Step-by-step explanation:
First we find the distance of the length and width of the rectangle.
Distance between E and F = Distance EF
Distance EF = √(∆y²-∆x²)
= √[(5-7)² + (1-7)²] = √[(-2)² + (-6)²]
= √(4+36) = √40
Distance EF = 2√10
Distance between F and G = Distance FG
Distance FG = √(∆y²-∆x²)
= √[(2-5)² + (2-1)²] = √[(-3)² + (1)²]
= √(9+1) = √10
Distance FG = √10
Length= distance EF = distance HG
And width = distance FG = distance EH
Perimeter of rectangle = 2(length + width)
Perimeter of rectangle = 2(2√10 + √10)
= 2(3√10)
Perimeter of rectangle = 6√10 units (the attachment isnt clear. It seems the answer is in option B)
