Mathematics
1 answer:
Oduvanchick [21]3 years ago
8 0

Answer:

138.3ft^3

Step-by-step explanation:

Volume for cylinders : V = pi*r^2*h

Volume for cones : V = pi*r^2*(h/3)

Since we know the radius (r) is 2 and the height is 10 and 3 for the cylinder and cone respectively, all we do is plug in.

Volume for cylinder is about 125.7ft^3

Volume for cone is about 12.6ft^3

Then just add them together for a total of 138.3ft^3

lawyer [7]

Answer:

First\ monthly\ payment= $858.69

Step-by-step explanation:

From the Question we are told that

Borrows $65,000

Annual interest  8.5%

Monthly repayment over 8 years

Generally PV of annuity with growth is mathematically represented as

where PV is present value

PV of annuity with growth X= (P/ (r-g)) * (1- ((1+g)/(1+r))^n)

     \frac{P}{\frac{8\%}{y12-0.2\%} } *(1-((1+0.2\%)/(1+8.5\%/12))^(^8^*^1^2^)^)=65000

    196.7213115P* 0.384791918=65000

     196.7213115P=65000/0.384791918

    196.7213115P=168922.4668

     P= 168922.4668/196.7213115

    P= 858.6892063

First\ monthly\ payment= $858.69

Write the ratio as a ratio of a whole numbers using fractional notation 6 1/2 to 15 1/6
motikmotik
\bf 6\frac{1}{2}:15\frac{1}{6}\qquad 
\begin{cases}
6\frac{1}{2}\implies \cfrac{6\cdot 2+1}{2}\\\\
15\frac{1}{6}\implies \cfrac{15\cdot 6+1}{6}
\end{cases}\implies \cfrac{ \frac{6\cdot 2+1}{2}}{\frac{15\cdot 6+1}{6}}\\\\
-----------------------------\\\\
\cfrac{\frac{a}{b}}{\frac{c}{{{ d}}}}\implies \cfrac{a}{b}\cdot \cfrac{{{ d}}}{c}\qquad thus
\\\\\\
\cfrac{6\cdot 2+1}{2}\cdot \cfrac{6}{15\cdot 6+1}
