We know that
<span>applying the Pythagorean theorem
c</span>²=a²+b²
c is the <span>length of the diagonal
a=100 yd
b=130 yd
c</span>²=100²+130²-------> c²=26900---------> c=√26900 units----> c=10√269 units
the answer is
the length of the diagonal is 10√269 units or 164.012 units
Answer:
297 cards in a year
Step-by-step explanation:
There are 12 months in a year, and he gets 2 packs of cards every month.
12*2 = 24 packs of cards a year
He gets 3 extra packs of cards for his birthday.
24 + 3 = 27 packs of cards
There are 11 cards in each pack.
27 X 11 = 297 cards in a year
Answer:
28 feet
Step-by-step explanation:
area of a square = side times side; the sides are equal
50 = side times side or 50 = side^2
sqroot of 50 = sqroot of side^2
7 feet is about the size of the side of the square so using that information..
2 length + 2 width or 4 side
4 times 7 = 28
the perimeter is 28 feet
Problem 4
<em>A</em>
If he is staying in the same place km for 1/2 hour, you can assume he's eating lunch or something. He hasn't moved at all, so his speed = distance over time = 0/(0.5) hours = 0
0 = answer
<em /><em>B
</em>Watch out for this. It's a little bit nasty. He starts out at 20 km He ends up at 0 km. It means he is going back to were he started from. If it said velocity, you'd have a problem.
<em>
</em>The time taken is 1.5 to 3 hours = 1.5 hours
His speed is d/t
<em>His speed is 20/1.5 = 13.33 km/hr.
</em>Speed = total distance / total time
total time = 3 hours.
Total distance = 40 km which is what the odometer would show.
Speed = 40 km/3 hours = 13.33 km/hour
<em>C
</em>You could just read the graph. He is 10 km from home.
