a manufacturer of bicycle parts requires that a bicycle chain have a width of 0.3 inch with an absolute deviation of at most 0.0

quester [9]

Answer:

$|w-0.3| \leq 0.0003$

And solving we got:

$-0.0003 \leq w-0.3 \leq 0.0003$

$0.3-0.0003 \leq w \leq 0.3+0.0003$

$0.2997 \leq w \leq 0.3003$

Step-by-step explanation:

For this case we can define the following notation:

$W$ represent the width

And we want a maximum error of 0.0003 so we can set up the following equation:

$|w-0.3| \leq 0.0003$

And solving we got:

$-0.0003 \leq w-0.3 \leq 0.0003$

$0.3-0.0003 \leq w \leq 0.3+0.0003$

$0.2997 \leq w \leq 0.3003$

Samantha’s parents give her $10 per week. For each chore that she does not complete, she must repay her parents $1. Which graph

jonny [76]

The y-intercept (initial value) is 10 and it has a slope of -1, so this is the first graph.

Write the difference in simplest form 11/12-2/12

g100num [7]

Simple. first make sure there are common denominators. There is, thus, you can now subtract.

11/12-2/12.

11-2=9

and you don't subtract denominators.

Then, 9/12
you can simplify even more by dividing both the numerator and denominator by 3. So 9/3=3 and 12/3=4

So, in simplest form, your answer is 3/4.

Calculate the number of kilograms of mercury required to fill a pool that is 20.0 m x 50.0 m x 10.0 m. The density of mercury is

malfutka [58]

Answer:

$m=135000000 Kg$

Step-by-step explanation:

To find the number of kilograms of mercury we need to find how to relate density, mass and, volume. For this we shall recall the density formula:

$\rho=\frac{m}{V}$

where $\rho$ is the density, $m$ is the mass and, $V$ is the volume.

We have the density and want to compute the mass so now we want to know the volume of the pool.

The volume of a rectangular pool is given by the fomula:

$V= (length)(heigh)(width)$ .

So for our pool

$V= (20)(50)(10)$ .

$V= 10000m^{3}$ .

Our density is in $g/mL$ , so the last thing we need to do before computing the mass is to express the density in $Kg/m^{3}$ (this is because we want our mass in $Kg$ and, we have our volume in $m^{3}$ ).
