Mathematics

An integer can be positive, negative, a whole number, or a decimal.
So basically, just simplify 9 and 3/2.
3/2 = 1 and 1/2
1 and 1/2 = 1.5
9 + 1.5 = 10.5
9 and 3/2 as an integer is 10.5.

Volume of the pyramid:

V=\dfrac{s^2h}3

Perimeter of the cross-section:

40=\sqrt2\,s+2\sqrt{\dfrac{s^2}2+h^2}=\sqrt2\left(s+\sqrt{s^2+2h^2}\right)

\implies h=\sqrt{\dfrac{(20\sqrt2-s)^2-s^2}2}=\sqrt{400-20\sqrt2\,s}

Area of the cross-section:

P=\dfrac12(\sqrt2\,s)h=\dfrac{sh}{\sqrt2}

\implies P=\dfrac{s\sqrt{400-20\sqrt2\,s}}{\sqrt2}=s\sqrt{200-10\sqrt2\,s}

First derivative test:

\dfrac{\mathrm dP}{\mathrm ds}=\dfrac{20\sqrt2-3s}{\sqrt{4-\dfrac{\sqrt2}5s}}=0\implies s=\dfrac{20\sqrt2}3

Then the height of the cross-section/pyramid is

h=\sqrt{400-20\sqrt2\,s}=\dfrac{20}{\sqrt3}

The volume of the pyramid that maximizes the cross-sectional area P is

V=\dfrac{\left(\frac{20\sqrt2}3\right)^2\frac{20}{\sqrt3}}3=\dfrac{16000}{27\sqrt3}

The ratio of color in a color bag is 3:2:1 for red, blue, and yellow respectively. If there are 9 yellow, how many blue and how
butalik [34]
3:2:1
r:b:9
To get to 9 from 1, you are multiplying by 9.
Therefore, multiply each number by 9.
27:18:9

So, 27 red and 18 blue.

Hope this helps!!

Why do you think gas stations often quote a price per gallon that ends in 9/10 of a cent? Do you think this is an appropriate us
arlik [135]
The practice of tacking 9/10 of a cent on the end of a gas price goes back to when gas cost only pennies per gallon and was a tax imposed by state and federal governments. Gas stations added the fraction of a cent on the end of the price instead of rounding up the price.
