Find the length of the arc on a circle with the radius of 2.4 km and is intercepted by a central angle measuring 150°. Leave you

djverab [1.8K]

Formula to find the arc length is:

$s=\frac{\theta}{360} 2\pi r$

Where, s= arc length,

r = radius of the circle

\theta = central angle in degrees.

According to the given problem, \theta= 150 and r =2.4.

So, first step is to plug in these values in the above formula to get the arc length.

$s=\frac{150}{360} *2\pi *2.4$

= $\frac{5}{12} *2\pi *2.4$

$=0.41667*2\pi *2.4$

$=2\pi$

So, arc length is $2\pi$ .

An object with a mass of 3.0 g raises the level of water in a graduated cylinder from 25.1 mL to 33.1 mL. What is the density of

evablogger [386]

The displaced volume of the water, because of the submersion of the object, is equal to the volume of the object.

So to find the volume of the object we calculate the difference in volume of water:
33.1-25.1 = 8 ml

Since 1 mL of water has the volume of 1cm^3, then the volume of the object is 8 cm^3.

The density of the object is found by the formula:

density= mass/volume= (3 g) / (8 cm^3) = 3/8 (g/cm^3)= 0.375 g/cm^3

Answer: 0.375 g/cm^3

A company that manufactures hair ribbons knows that the number of ribbons it can sell each week, x, is related to the price p pe

mel-nik [20]

Given:

The number of ribbons it can sell each week, x, is related to the price p per ribbon by the equation:

$x=1000-100p$

To find:

The selling price if the company wants the weekly revenue to be $1,600.

Solution:

We know that the revenue is the product of quantity and price.

$R=xp$

$R=(1000-100p)p$

$R=1000p-100p^2$

We need to find the value of p when the value of R is $1600.

$1600=1000p-100p^2$

$1600-1000p+100p^2=0$

$100(16-10p+p^2)=0$

Divide both sides by 100.

$p^2-10p+16=0$

Splitting the middle term, we get

$p^2-8p-2p+16=0$

$p(p-8)-2(p-8)=0$

$(p-8)(p-2)=0$

Using zero product property, we get

$p-8=0$ or $p-2=0$

$p=8$ or $p=2$

Therefore, the smaller value of p is $2 and the larger value of p is $8.
