Answer: A
Step-by-step explanation:
First route: 70 miles divided by 55 mph = 1.27 hours
Second route: 85 miles divided by 65 mph = 1.31 hours
The first route takes less time so it’s better
X=16 put 5 in the place of Y Then solve for X
5=1/2x-3 add three on both sides
8=1/2x multiply 2 on both sides
16=x
x=16 And thats your answer
Answer:
1/4 the new area
Step-by-step explanation:
Kimberly wants to enlarge hut 5‘ x 10‘ rectangular patio by multiplying its dimensions by two how old the area of the patio be affected
Given that:
Initial dimension of patio = 5' by 10'
Initial area of patio = Area of rectangle = Length * width
Area of patio = 5 * 10 = 50 in²
If dimension is multiplied by 2
New dimension :
5* 2 by 10*2 = 10' by 20'
New area of patio :
10 * 20 = 200 in²
50 /200 = 1/4
The old area will be 1/4 the size of the new area of the patio
Your choices A and C are the same
but the decimal of 1/11 is 0.090909
so your answer would be 2.09
