Answer:
<h2>
512 m²</h2>
Step-by-step explanation:
The surface area is a sum of areas of four triangles with base of <em>8 m</em> and hight of <em>12 m</em> and areas of five squares with sides of <em>8 m.</em>
<em />
<h3>
Sa = 4×¹/₂×8×12 + 5×8² = 192 + 320 = 512 m²</h3>
L=w+2 and 2w+2l=40
Substitute length for w+2 in perimeter formula.
2w+2(w+2)=40
2w+2w+4=40
4w+4=40
4w=36
w=9
l=w+2
l=9+2
l=11
a=lw=11*9=99 meters
The answer would be 10 because the full side is 20 and it’s only asking for half the side so it would be 10

Step-by-step explanation:
Answer:
A) 46 mph
Step-by-step explanation:
<em>Step 1: To find the speed, you need to find the distance and time to travel between Chicago and Cleveland.</em>
Distance = 354 miles
Time = 9: 50 am to 5: 30 pm
Time = 7 hours 40 minutes
<em>Step 2: Convert time to hours</em>
1 hour = 60 minutes
40 minutes = 60/40 = 2/3 hours
<em>Step 3: Find the speed</em>
Speed = Distance/Time
Speed = 354/7 + 2/3
Speed = 1062/23
Speed = 46.17 miles per hour rounded off to 46 mph
Therefore, A is the correct answer.
