4 0

Answer:

largest 4 digit number × largest 3 digit number

=9999 × 999

(10000-1)×(1000-1) = (a-b)(c-b)= ac-ab-bc+b^2

10000000-10000-1000+1 = 9989001

A cube which measures 27 inches on one side
ExtremeBDS [4]

Answer:

i wont steal your education so here To find the volume of any cube you need to know the length, width and height. The formula to find the volume multiplies the length by the width by the height. The good news for a cube is that the measure of each of these dimensions is exactly the same. Therefore, you can multiply the length of any side three times.

Points (−7, 5) and (7, 5) on the coordinate grid below show the positions of two players of a football team:
Greeley [361]

Visually, we can see that Player 1 and Player 2 are at the <em>same vertical point</em>, and we can confirm that numerically - both of their y-coordinates are 5. We can also see that it looks like the points mirror each other horizontally; numerically, their x-coordinates are 7 and -7 - the same basic number given different signs.

To find the axis of reflection, we want to find the line that passes right through the middle of the two points which, in this case, is the y-axis. Option 3 is the appropriate response in that light.

What is the range of possible values for x?
Talja [164]
The minimum value for 2x is 0 
<span>the maximum value is achieved when A, D and C are collinear and the quadrilateral ABCD becomes an isosceles triangle ABC </span>
<span>base AB = 52 and vertical angle 2x + 34° </span>

<span>For the sine law </span>
<span>(sin 2x)/22 = (sin ADB)/AB </span>
<span>(sin 34°)/30 = (sin BDC)/BC </span>

<span>is given that AB = BC, and sin ADC = sin BDC because they are supplementary, so from </span>
<span>(sin ADC)/AB = (sin BDC)/BC </span>

<span>it follows </span>
<span>(sin 2x)/22 = (sin 34°)/30 </span>

<span>sin 2x = 22 (sin 34°)/30 </span>

<span>2x = asin(22 (sin 34°)/30) ≈ 24.2° </span>

<span>x = 0.5 asin(22 (sin 34°)/30) ≈ 12.1° </span>

<span>0 < x < 12.1°</span>
