Answer: old McDonald has 54 chickens and 2 cows.
Step-by-step explanation:
Let x represent the number of chickens that old McDonald have.
Let y represent the number of cows that old McDonald have.
He counted 56 heads. A chicken and a cow has one head each. It means that
x + y = 56
He counted 116 legs. A chicken has 2 legs and a cow has 4 legs. It means that
2x + 4y = 116 - - - - - - - - -1
Substituting x = 56 - y into equation 1, it becomes
2(56 - y) + 4y = 116
112 - 2y + 4y = 116
- 2y + 4y = 116 - 112
2y = 4
y = 4/2 = 2
x = 56 - y = 56 - 2
x = 54
The answer which are true about the two rectangular pyramids are;
- The composite figure consists of two rectangular pyramids.
- The composite figure can be broken down into rectangular prisms.
- The volume of the composite figure is 1.5(9)(5) + 1.5(9)(5).
<h3>Which statements about the composite figure are true?</h3>
It follows from the task content that the dimensions of the rectangular prisms are the same and are as given.
On this note, it follows that the volume of the composite figure is; 1.5(9)(5) + 1.5(9)(5) = 135units³.

<span>first mulitply 2*5 =15
then change 4 into an x
now 4/2.5= 1.6
finally do 15 times and 1.6 is 24</span>
