The Earth's circumference measured at the equator is approximately 1.3148 × 108 feet. What is the number written in standard for

maks197457 [2]

Answer:

The number written in standard form is $131,480,000$

Step-by-step explanation:

we have

$1.3148*10^8$

we know that

$10^8=100,000,000$

substitute

$1.3148*10^8=1.3148(100,000,000)$

Remember that

When multiplying decimals by 10, move the decimal point one space to the right

In this case move the decimal point eight spaces to the right

$1.3148(100,000,000)=131,480,000$

therefore

The number written in standard form is $131,480,000$

The revenue for a company producing widgets is given by y = -20x2 - 50x + 200, where x is the price in dollars for each widget.

lisov135 [29]

Answer:

The price is x = $2.779

Step-by-step explanation:

From the question we are told that

The revenue is $y = - 20x^2 - 50 x + 200$

The cost of production is $y = 30 x - 10$

Generally at break even point the cost of production is equal to the revenue

$-20x^2 -50x + 200 = 30x-10$

=> $20x^2 +20 -210 = 0$

Using the quadratic formula to solve this equation we have that

x = $2.779

What is the height of the cone below? - 3 - 9 - 27 - 75

Rasek [7]

$\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\ \end{cases}\implies V=\pi r^2\cdot \cfrac{h}{3}~~ \begin{cases} \pi r^2=&area~of\\ &circular\\ &base\\ \cline{1-2} \stackrel{B}{\pi r^2}=&5\\ V=&45 \end{cases} \\\\\\ 45=5\cdot \cfrac{h}{3}\implies 135=5h\implies \cfrac{135}{5}=h\implies 27=h$

$\bf \begin{array}{ccllll}
used&new\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1&3\\
u&720
\end{array}\implies \cfrac{1}{u}=\cfrac{3}{720}\implies \cfrac{720\cdot 1}{3}=u$
