Answer:
16.4 m²
Step-by-step explanation:
length = 4.6 m
breadth = 360 cm = 360 ÷ 100 = 3.6 m
Perimeter = 2*(l + b)
= 2 * ( 4.6 + 3.6)
= 2 * 8.2
= 16.4 m²
Answer:
Y=10x
(multiply 10 times the salamanders)
Step-by-step explanation:
a formula that can be used for this circumstance is a linear y=mx+b problem. for 1 salamander there are 10 frogs. so with this we can state that y=10x. whatever you plug into the x for the number of salamanders will give you the answer of how many frogs are in the pond. for example.
Y=10x
Y=10(3)
Y=30
30 frogs.
also because 10 is a nice number you can just multiply the number of salamanders times 10. 3*10=30
Answer:
<h3>28</h3>
Step-by-step explanation:
Area of a square =
![s^2](https://tex.z-dn.net/?f=s%5E2)
Perimeter =
![4\times s](https://tex.z-dn.net/?f=4%5Ctimes%20s)
Where s = side
Solve for s using the area
![A =49\\\\49 = s^2\\\\Square\:root \:both\:sides\:of\:the\:equation\\\\\sqrt{49} = \sqrt{s^2} \\\\7 =s\\\\s =7](https://tex.z-dn.net/?f=A%20%3D49%5C%5C%5C%5C49%20%3D%20s%5E2%5C%5C%5C%5CSquare%5C%3Aroot%20%5C%3Aboth%5C%3Asides%5C%3Aof%5C%3Athe%5C%3Aequation%5C%5C%5C%5C%5Csqrt%7B49%7D%20%3D%20%5Csqrt%7Bs%5E2%7D%20%5C%5C%5C%5C7%20%3Ds%5C%5C%5C%5Cs%20%3D7)

Answer:
The first choice
Step-by-step explanation:
Perpendicular lines intersect to form right angles, like the x- and y-axis on a coordinate plane.
