How many times longer is the diameter of a grain of sand than the diameter of the average cell in the human body? Show your work

oee [108]

<span>A grain of sand has a diameter of slightly over 1 mm and the average diameter of a human cell is 8 micrometers. Putting them into common terms (meters) gives: 1.03 * 10^-3 m and 8*10^-6 m, respectively. Dividing the two to give a ratio leads to a value of (1.03*10^-3)/(8*10^-6), or 128.75 times longer for the grain of sand.</span>

A landscaping company is delivering crushed stone to a construction site .The Table shows the total weight in pounds W, of n loa

irina1246 [14]

Answer:

Option (C)

Step-by-step explanation:

From the given table,

Dependent variable is the weight of each load and independent variable is number of loads of crushed stones.

Let the equation that represents the total weight is,

W = mn + b

Where 'm' = slope of the line

b = y-intercept

n = number of loads

Since graph starts from the origin (0, 0), y - intercept 'b' will be 0.

Two points lying on the line are (0, 0) and (1, 2000)

Slope of the line 'm' = $\frac{y_2-y_1}{x_2-x_1}$

= $\frac{2000-0}{1-0}$

=2000

Therefore, equation will be,

W = 2000n

Option (C) will be the answer.

A safety regulation states that the height hh of a guardrail should be 106 centimeters with an absolute deviation of no more tha

iren [92.7K]

Let us say that h is the height of the guardrail. Therefore the inequality equation that we can generate from this scenario is:

| h – 106 | = ± 7

There are two ways to solve this, either the equation is positive or negative.

When the equation is positive, therefore:

| h – 106 | = 7

h = 7 + 106 = 113 cm

When the equation is negative, therefore:

| h – 106 | = - 7

h = -7 + 106 = 99 cm

So the height must be 99 cm to 113 cm

A school district’s income from property taxes was estimated at $1.4 million last year, but the actual income came in at $1.25 m

erastova [34]

Answer:

$.15$ $million$ $dollars$

Step-by-step explanation:

We know that the school district's income from property taxes were estimated at 1.4 million, but then we see that the actual income was 1.25 million.

To find the actual error, we must subtract 1.25 million 1.4 million.

$1,400,000 - 1,250,000 = 150,000$

150,000 thousand dollars or .15 million dollars.
