of the number of gallons of water used by this
business when the cost of water is $180?

Answers

Answer:

90,000

Step-by-step explanation:

As per the given scatter plot, for the cost of $180, the number of gallons of water used is 90,000.

What is a scatter plot?

The association between two numerical variables measured for the same individuals is displayed in a scatterplot. One variable's values are displayed on the horizontal axis, and the other variable's values are displayed on the vertical axis.

Here,
According to the question, the maximum limit shown on the scatterplot is $180 for 90 units on the scatterplot,
Where horizontal units are represented as the scale of 1 unit = 1000 units.
So for the maximum.
For the cost of $180 the gallons of water used is 90×1000.

Thus, as per the given scatter plot, for the cost of $180, the number of gallons of water used is 90,000.

whats all the fractions that are eqvalent to 4/3

Answers

Answer:8/6,12/9

Step-by-step explanation:

The fraction 8/6 is equal to 4/3 when reduced to lowest terms. To find equivalent fractions, just multiply the numerator and denominator of that reduced fraction (4/3) by any interger number, ie, multiply by 2, 3, 10, 30... 8/6 is equivalent to 4/3 because 4 x 2 = 8 and 3 x 2 = 6 12/9 is equivalent to 4/3 because 4 x 3 = 12 and 3 x 3 = 9

Answer:

4/3 = 8/6 = 12/9 = 16/12

= 20/15 = 24/18 = 28/21 = 32/24

= 36/27 = 40/30 = 44/33 = 48/36

= 52/39 = 56/42 = 60/45 = 64/48

= 68/51 = 72/54 = 76/57 = 80/60

= 84/63 = 88/66 = 92/69 = 96/72

= 100/75 = 104/78 = 108/81 = 112/84

= 116/87 = 120/90 = 124/93 = 128/96

= 132/99 = 136/102 = 140/105 = 144/108

= 148/111 = 152/114 = 156/117 = 160/120

= 164/123 = 168/126 = 172/129 = 176/132

= 180/135 = 184/138 = 188/141 = 192/144

= 196/147 = 200/150 = 204/153 = 208/156

= 212/159 = 216/162 = 220/165 = 224/168

= 228/171 = 232/174 = 236/177 = 240/180

= 244/183 = 248/186 = 252/189 = 256/192

= 260/195 = 264/198 = 268/201 = 272/204

= 276/207 = 280/210 = 284/213 = 288/216

= 292/219 = 296/222 = 300/225 = 304/228

= 308/231 = 312/234 = 316/237 = 320/240

= 324/243 = 328/246 = 332/249 = 336/252

= 340/255 = 344/258 = 348/261 = 352/264

= 356/267 = 360/270 = 364/273 = 368/276

= 372/279 = 376/282 = 380/285 = 384/288

= 388/291 = 392/294 = 396/297 = 400/300

The regular polygon below is rotated about its center . Which angle of rotation will carry the figure onto itself ?

Answers

Answers is 3

360° = 72° 216o is a multiple of 72

The angle of rotation will carry the figure onto itself is 216 degrees

The measure of angle at the center of the polygon is 360 degrees. i.e.

[tex]\theta = 360^o[/tex]

The number of sides of the regular polygon is 5. i.e.

[tex]n = 5[/tex]

So, the smallest angle of rotation that maps the polygon onto itself is

[tex] = \frac{\theta}{n}[/tex]

This gives

[tex]\alpha = \frac{360}{5}[/tex]

[tex]\alpha = 72[/tex]

Other angles that map the shape onto itself, must be a multiple of 72. i.e.

[tex]\alpha = 72, 144, 216,288,360....[/tex]

Hence, the angle of rotation will carry the figure onto itself is 216 degrees

The answer is 10


Explanation: First you cross-multiply to get 2x=20 and then divide by 2 to get x=10

9514 1404 393

Answer:

  x = 10

Step-by-step explanation:

Using your number sense, you recognize that a fraction equivalent to 2/5 that has 4 in the numerator is 4/10. This tells you x = 10.

__

The usual instructions for solving this algebraically are to "cross multiply", then divide by the coefficient of x.

  2/5 = 4/x . . . . given

  2x = 20 . . . . . multiply by 5x on both sides

  x = 10 . . . . . . . divide by 2

__

You can do the above two steps both at once: multiply by 5/2x.

  (2/5)(5/2x) = (4/x)(5/2x)

  x = 20/2 = 10

To make 3 litres of pale purple paint you mix:
1.5 litres red
1.25 litres of blue
0.25 litres of white paint.
a How much red paint is needed to make 8 litres of paint?

Answers

Answer:

We need 4 litres of red paint.

Step-by-step explanation:

We need to take their respective precentages to compare the 3 litres of paint to 8 litres of paint.

[tex] \frac{1.5}{3} \times 100\% = 50\% \\ \frac{1.25}{3} \times 100\% = 41.67\% \\ \frac{0.25}{3} \times 100\% = 8.33\% \\ [/tex]

Now, we know that the pale purple paint contains 50% red paint, 41.67% blue paint, and 8.33% white paint.

Now, we will transfer these percentages to the 8 litres of paint:

[tex]50\% \: of \: 8 \: litres = 0.5(8) = 4 \: litres \\ 41.67\% \: of \: 8 \: litres = 0.4167(8) = 3.3336 \: litres \\ 8.33\% \: of \: 8 \: litres = 0.0833(8) = 0.6664 \: litres[/tex]
