Elisa, e = 11mins

Prenav,p = 13mins

time to complete, t

1 = t( 1/11 + 1/13) = t (24/143)

t = 143/24 = 5.96min

Answer is A 5.96mins

What type of triangle has side lengths 12, 13, and 2√3?

Travka [436]

Answer:

The triangle is an obtuse scalene triangle

Step-by-step explanation:

we know that

if $c^{2}=a^{2}+b^{2}$ --------> is a right triangle

if $c^{2}>a^{2}+b^{2}$ --------> is an obtuse triangle

if $c^{2}$ --------> is an acute triangle

where

c is the greater side

we have

$c=13\ units$

$a=12\ units$

$b=2\sqrt{3}\ units$

so

$c^{2}=13^{2}=169$

$a^{2}+b^{2}=12^{2}+(2\sqrt{3})^{2}=156$

so

$c^{2}>a^{2}+b^{2}$ -------> is an obtuse triangle

Remember that

The given triangle has three different length side

so

Is a scalene triangle

therefore

The triangle is an obtuse scalene triangle

300-7[4(3+5)]+3 to the 3rd power

Mila [183]

Answer:

The answer is 103

Step-by-step explanation:

The given expression is:

300-7[4(3+5)]+3 to the 3rd power

3 to the 3rd power means 3^3

Therefore,

300-7[4(3+5)]+3^3

First we will solve the round bracket and find the cube

300-7[4(8)]+27

Now we will solve square bracket

300-7[32]+ 27

300-224+27

76+27

103

Thus the answer we get is 103....

In 1970 the population of the United States was 203 million. Ten years later, in 1980, the population of the United States was 2

andrezito [222]

Answer:

The exponential function for the US population is:

$y = 203\cdot e^{0.0107\cdot t}$

Step-by-step explanation:

Let be supposed that US population can be modelled by means of the following exponential function:

$y = A \cdot e^{B\cdot t}$

Where:

$t$ - Time, measured in years. Where t = 0 for 1970.

$A$ - Initial population, in millions inhabitants.

$B$ - Exponential rate constant, in years.

$y$ - Population, in millions inhabitants.

Each constant is found hereafter:

A

$203 = A \cdot e^{B\cdot 0}$

$203 = A \cdot 1$

$A = 203$

B

$226 = 203\cdot e^{B\cdot 10}$

$\frac{226}{203} = e^{10\cdot B}$

$10\cdot B = \ln \frac{226}{203}$

$B = \frac{1}{10}\cdot \ln \frac{226}{203}$

$B = 0.0107$

The exponential function for the US population is:

$y = 203\cdot e^{0.0107\cdot t}$
