Answer:
<em>the unit rate is 0.8x per unit y</em>
<em></em>
Step-by-step explanation:
the proportional relationship is y =
this means that the constant of proportionality k = = 0.8
re-writing, we have
<em>y = 0.8x</em>
<em>therefore, the unit rate is 0.8x per unit y</em>
Answer:
The bottle of perfume A contains more glass
Step-by-step explanation:
we know that
The surface area of the square pyramid is equal to the area of the square base plus the area of its four triangular faces
step 1
Find the surface area of Perfume A
step 2
Find the surface area of Perfume B
step 3
Compare the surface areas
therefore
The bottle of perfume A contains more glass
Answer:
The area of the rectangle on the left side is
The area of the bottom rectangle is
The total area of the composite figure will be
Step-by-step explanation:
The area of any given rectangle can be found by multiplying the length of that rectangle by its width. The rectangle on the left side has a length of 9cm but the width is unknown. To find the width, we subtract 6cm from the width of the bottom rectangle: 10cm. And that gives us 4cm.
Therefore, we can now calculate the area to be: length × width = 9cm × 4cm = 36cm²//
The area of the bottom rectangle can be found similarly by multiplying the length: 2cm by the width: 6cm of that rectangle. And the result gives us: 2cm × 6cm = 12cm²//
The total area of the composite figure is calculated by adding the results from the left and bottom rectangles together. And that gives us: 36cm² + 12cm² = 48cm²//
