210 at 8% for 7 years

Mathematics
1 answer:
Novay_Z [31]3 years ago
5 0

Answer:

44.040192

Step-by-step explanation:

I barely remember doing this in math. I did some research on the question and that's the answer that I got. If I'm not wrong, the formula you are supposed to use is:

y = a(r)^t

A being the regular number in the problem (210).

R is the rate/ ratio (8% which would be converted to 0.8).

T is the time (7 years).

Put the equation together, and you get y = 210(0.8)^7. When you plug it into a calculator, you get 44.040192.

Sorry for the long explanation, but I hope this helps you solve your problem!

If ADE ABC in this diagram, which pair of ratios must necessarily be equal?
ad-work [718]

Answer:

\frac{AD}{AB}=\frac{AE}{AC}=\frac{DE}{BC}

Step-by-step explanation:

we know that

Triangle ADE and Triangle ABC are similar

therefore

the ratio of their corresponding sides are equal

so

\frac{AD}{AB}=\frac{AE}{AC}=\frac{DE}{BC}

Paha777 [63]

Expenses of respondents in a survey is a quantitative data and the level of measurement is a ratio scale.

<h3>What is a Qualitative and a Quantitative Data?</h3>

A quantitative data can be described as a type of data that you can measure or counted, and also given a numerical value to, while a qualitative data is a type of data that cannot be expressed using numbers.

Examples of quantitative data include, number of students in a class, weight of students in a class, etc.

Examples of qualitative data include hair color, religion, nationality, etc.

Expenses of respondents can be given numerical values, therefore, expenses of respondents in a survey is a quantitative data and the level of measurement is a ratio scale.

Use a triple integral to find the volume of the given solid. the solid enclosed by the cylinder x2 + y2 = 9 and the planes y + z
Alexxx [7]
Using cylindrical coordinates, we have

\begin{cases}x=r\cos\theta\\y=r\sin\theta\\z=\zeta\end{cases}

so that the Jacobian gives

\mathrm dV=\mathrm dx\,\mathrm dy\,\mathrm dz=r\,\mathrm dr\,\mathrm d\theta\,\mathrm d\zeta

The volume is given by the triple integral

\displaystyle\int_{\theta=0}^{\theta=2\pi}\int_{r=0}^{r=3}\int_{\zeta=2}^{\zeta=14-r\sin\theta}r\,\mathrm d\zeta\,\mathrm dr\,\mathrm d\theta
=\displaystyle\int_{\theta=0}^{\theta=2\pi}\int_{r=0}^{r=3}r(14-r\sin\theta-2)\,\mathrm dr\,\mathrm d\theta
=\displaystyle\int_{\theta=0}^{\theta=2\pi}\int_{r=0}^{r=3}(12r-r^2\sin\theta)\,\mathrm dr\,\mathrm d\theta
=\displaystyle\int_{\theta=0}^{\theta=2\pi}(54-9\sin\theta)\,\mathrm d\theta
=108\pi
