The question you asked uses the concept of division, something that a bit tricky at first but gets easier as you master it!
So first let’s write and equation for your problem:
Let x = the amount of calories she burns each hour.
So we already know that Vivi was drumming for 3 hours, that she burned 756 calories, and that she burned the same amount of calories each hour.
Since she burned 756 calories in total, we know that the equation will have to equal 756:
= 756
We also know that the answer will be 3(hours) times x(the amount of calories), so now we just plug it into the equation:
3x = 756
To find what ‘x’ equals we have to divide both side by 3:
3x/3 = 756/3
Now all we have to do is simplify and you have your answer!
x = 252
And there you have it, Vivi burned 25 calories per hour!
Hope this helps! :)
The number of blocks of clay needed by Hyla is 30 blocks
<h3>What is area?</h3>
Area is the region bounded by a plane shape.
To calculate the number of blocks of clay needed by Hyla, we find the area of the bottom of the box and divide it by the area of the block.
Formula:
- n = LWH/lwh............... Equation 1
Where:
- n = Number of blocks of clay needed by Hyla
- L = Length of the bottom of the box
- W = Width of the bottom of the box
- H = Height of the box
- l = Length of the bottom of the block
- w = Width of the block
- h = Height of the block.
From the question,
Given:
- L = 24 cm
- W = 20 cm
- H = 2 cm
- l = 4 cm
- w = 4 cm
- h = 2cm
Substitute these values into equation 1
- n = (24×20×2)/(4×4×2)
- n = 30
Hence, The number of blocks of clay needed by Hyla is 30 blocks
