Your answer would be the last option, 80 cm.
As this is a right triangle, you can use Pythagoras's Theorem, a² + b² = c², where 'c' is the hypotenuse and 'a' and 'b' are the legs, to find the missing side.
This gives us:
48² + 64² = 2,304 + 4,096 = 6,400
√6,400 = 80
So 80 is your answer.
I hope this helps!
A volleyball uniform costs $13 for the shirt, $11 for pants, and $8 for socks. Write two equivalent expressions for the total cost of 12 uniforms. Then find the cost.
Write an expression for the cost of 1 uniform, add $13, $11 and $8 .
$13+$11+$8
Write an expression for the cost of 12 uniforms, multiply 12 by the cost of 1 uniform.
12($13+$11+$8)
Simplify using the distributive property.
=12⋅13+12⋅11+12⋅8=156+132+96
Now Add.
=384
So, the total cost of 12 uniforms is $384 .
Answer:
Light is moving at the speed = 77.78 km/min
Step-by-step explanation:
Given:
Distance between island and point P = 5 km
Moving along the the shoreline when it is 1 km from P.
So, x = 1
From the above statement light makes seven revolutions per minute.
Therefore,
Solution:
From the given figure.
Substitute x = 1
-------------------(1)
Now, first we differentiate both side with respect to t.
Using chain rule.
Substitute from equation 1.
Substitute 
Applying cross multiplication rule.
Therefore, light is moving along the shore at the speed of 77.78 km/min
Answer:
A yes B No C Yes
Step-by-step explanation:
The length of the third side is greater than the difference and less than the sum of the two smallest sides.
8, 5, 7 Using the 5 and 7 the third side is > (7 - 5) and < (5 + 7)
the third side is > 2 and < 12 so 8 is OK
10, 3, 7 Use the two smallest number: 3 and 7
the third side is > (7 - 3) and < (3 + 7)
the third side is > 4 and < 10 No it is 10
9, 5, 15 Use the two smallest number 9, 5
the third side is > (9 - 5) and < (9 + 5)
the third side is > 4 and < 14 Yes
