Answer:the number of 2 legged animals in the zoo is 9
the number of 4 legged animals in the zoo is 7
Step-by-step explanation:
Let x represent the number of 2 legged animals in the zoo.
Let y represent the number of 4 legged animals in the zoo.
There a 46 legs in the exhibit in the zoo. This means that
2x + 4y = 46 - - - - - - - - - -1
There are 2 more 2 legged animals than 4 legged animals. This means that
x - 2 = y
Substituting y = x - 2 into equation 1, it becomes
2x + 4(x - 2) = 46
2x + 4x - 8 = 46
6x = 54
x = 54/6 = 9
Substituting x = 9 into x - 2 = y, it becomes
y = 9 - 2 = 7
<span>The circumference of a circle is the length that the circle would occupy if it were opened and laid flat on a surface as a straight line. For this reason, when calculating the distance travelled in circular motion, the circumference is used. The cirumference is calculated using: C = 2*pi*radius</span>
Answer:
<h3><ABC > <DBC.</h3>
Step-by-step explanation:
Given < DBC = < RST and we need to prove < ABC is greater than <RST.
First given statement:
< DBC = < RST
Reason: Given.
Second given statement :
<ABC = <DBC+ <ABD.
Reason: Angle addition theorem.
<em>Note: < ABC is the sum of angles <DBC and <ABD and we have < DBC = < RST. So it's an obvious thing that the sum of angles <DBC and <ABD is always greater than <RST.</em>
Also, <ABC is greater than <DBC.
Therefore, correct option for third statement is :
<h3><ABC > <DBC.</h3>
