Answer:

The new volume of an enlarged tank is 4000m³

Step-by-step explanation:

The scale factor has to be multiplied by the width, length and height so we will have to multiply it 3 times

h * w * l = 32 m³

(h*5) * (w*5) * (l*5)

if we rearrange the multiplications

(h * w * l) * 5 *5 * 5 =

v * 5 * 5 * 5 =

32m³ * 5 *5 *5 = 4000m³

Give the general form of the equation of the line through (1,2) and is perpendicular to the line passing through (-6,-3)(6,3)
olga nikolaevna [1]

Answer:

4x+3y-10=0

Step-by-step explanation:

first find the gradient of the line that is perpendicular to the line of interest.

y2-y1/x2-x1

3--3/6--6

=3+3/6+6

=9/12

3/4

The gradient of the line of interest is the negative reciprocal of 3/4. Therefore m is -4/3

next, substitute information into

y-y1=m(x-x1)

y-2=-4/3 (x-1)

multiply both sides of equation by 3

3y-6=-4 (x-1)

expand brackets

3y-6=-4x+4

rearrange in general form

4x+3y-10=0

The variables x and y vary inversely. Use the given values to write an equation relating x and y. Then find y when x=−3.
-BARSIC- [3]

Answer:

xy-3x=40, x=5

x(y-3)=40

y-3=(40/x)

y=(40/x)+3

y=(40/5)+3

y=8+3

y=11

This question is incomplete, the missing image is uploaded along this answer below.

<h3>What is the volume of the regular pyramid?</h3>

The volume of pyramid is expressed as;

V = ( 1/3 ) × l × w × h

Given that;

  • Length l = 8
  • Width W = 8
  • Height h = 6

We substitute our given values into the equation above.

V = ( 1/3 ) × 8 × 8 × 6

V = 128 unit³

The volume of the regular pyramid is 128 unit³.

Option D) 128 unit³ is the correct answer.
