Answer:
there are 40 boys
Step-by-step explanation:
32/4=8 5*8=40
To do 130% increase you multiply by 1.3 so you do 810 × 1.3 = 1053
Answer:
1/2 + 8 is equivalent to 1/2 - (-8)
0.5 - (-8) is ALSO equivalent to 1/2 - (-8)
0.5 + 8 is another equation that is equivalent to 1/2 - (-8)
Step-by-step explanation:
We have been given that a rectangle has a height to width ratio of 3:4.5.
Let h be height and w be width of rectangle.
We can set our given information in an equation as:


Now we will substitute h=1 in this equation.



We can see that width of rectangle is 1.5 times height of rectangle.
Our one set of dimensions of rectangle will be: height=1 and width=1.5.
We can get many set of dimensions for our rectangle by multiplying both height and width of rectangle by same number.
Multiplying by 5 we will get our dimensions as: height 5 and width 7.5.
Therefore, (1 and 1.5) and (5 and 7.5) dimensions for rectangle will be scaled version of our rectangle.
Well, to get the surface area, you do length x width x height. <span>Multiply the side length of the base by the slant height and divide by two. Then, multiply by 4. This will give you the lateral </span>surface area<span> of the </span>pyramid<span>.</span>
