Answer:
A. 1200
Step-by-step explanation:
Since 10 times 3 is 30, then 400 times 3 is 1200. Hope I helped!
Answer:
H = 11m
Step-by-step explanation:
As we know, volume = length * breadth/width * height
Given,
length = 6m
Breadth/width = 3 1/2 or 3.5
Height = ?
So, l * b * h = v
=> 6m * 3.5m * h = 231m
=> 21m * h = 231m
=> h = 231m /21m = 11m
Therefore, height = 11m / 11metres
Hope this helps
Answer:
X = 45°
Y = 72°
Step-by-step explanation:
There is a supplementary angle (an pair of angles that create a straight line is equal to 180°) and there is the rule that all three angles in a triangle equal 180° as well.
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
