Answer:
The Length of JM is 20.
Step-by-step explanation:
Given,
JKLM is a kite in which JL and KM are the diagonals that intersect at point A.
Length of AK = 9
Length of JK = 15
Length of AM = 16
Solution,
Since JKLM is a kite. And JL and KM are the diagonals.
And we know that the diagonals of a kite perpendicularly bisects each other.
So, JL ⊥ KM.
Therefore ΔJAK is aright angled triangle.
Now according to Pythagoras Theorem which states that;
"The square of the hypotenuse is equal to the sum of the square of base and square of perpendicular".

On putting the values, we get;

On taking square root onboth side, we get;

Again By Pythagoras Theorem,

On putting the values, we get;

On taking square root onboth side, we get;

Hence The Length of JM is 20.

Answer:
B
Step-by-step explanation:
Let the nickels = x
Let the dimes = y
You don't know the total value of either. Nor do you know the total number of either.
You only know the total value of both together.
7.80 added to anything makes it bigger than 7.80 A is wrong.
y cannot be alone it should be multiplied by 0.5 C is wrong
D is wrong for the same reason A is
B is the correct answer. That is the way you write the problem
Number of Coins and value on one side. Total on the other.
Answer:
572.3
Step-by-step explanation:
Diameter = 27m
Radius = d / 2 = 27 / 2 = 13.5m
Area = pi x r²
= 3.14 x (13.5)²
= 3.14 × 182.25
= 572.3
