Henry counted 350 Lockers in his school Hailey counted 403 Lockers in her school how does the 3in 350 compared to the three in 4
stiv31 [10]
The 3 in 350 represents 300

because 350=300+50+0, that is: 3 one hundreds +5 tens +0 ones


The 3 in 403, represents 3 because 403 = 400+3 that is 4 one hundreds, 0 tens and 3 ones.


Thus the 3 in the number 350 and  the 3 in the number 403 are not the same.

The 3 in the number 350 is one hundred time the 3 in the number 403.


Answer: The 3 in the number 350 is one hundred time the 3 in the number 403.

Enter the slope-intercept equation for the image of line ℓ after a clockwise rotation of 90°. (Hint: To find the image of line ℓ
Free_Kalibri [48]

Answer:

y = -2x - 2

Step-by-step explanation:

From the graph attached,

If the line 'l' passes through two points A(0, -1) and B(4, 1).

Rule for the rotation of any point (x, y), 90° clockwise about the origin is,

(x, y) → (y, -x)

By this rule,

A(0, -1) → A'(-1, 0)

B(4, 1) → B'(1, -4)

Let the equation of the line A'B' is,

y - y' = m(x - x')

where m = slope of the line A'B'

And (x', y') is a point lying on the line.

Slope of the line passing through A' and B' will be,

m = \frac{y_2-y_1}{x_2-x_1}

m = \frac{0+4}{-1-1}

m = -2

Therefore, equation of the line passing through (-1, 0) and slope = -2,

y - 0 = (-2)(x + 1)

y = -2x - 2

So the equation of the line after rotation of lie 'l' by 90° clockwise will be,

y = -2x - 2

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>

What is diameter:

in geometry, a <u><em>diameter</em></u> of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere.

What is radius:

In classical geometry, a <u><em>radius</em></u> of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.

Explanation:

The <u><em>diameter </em></u>is the line that goes across the center of the circle and double the <u><em>radius</em></u> which is half, therefore <u><em>KR</em></u> is the <u><em>correct answer.</em></u>

Answer:

<u><em>KR, D, or the last option.</em></u>

Statement answer:

<u><em>Segment KR is the Diameter of Q.</em></u>

Need help with this math ​
Taya2010 [7]

Answer:

\frac{114t}{v} =D

Step-by-step explanation:

It's all about algebraically manipulating the equation.  We want to get D by itself, so how do we do that?  Well, D is being multiplied by v and divided by 114, so we just need to do the opposite to both sides of the equation.  

You just multiply both sides by 114 and then divide both sides by v.  You could do it in either order since there is no addition or subtraction, if there was you would have to take that into consideration.
