What is the value of the missing angle?
a.120
b.130

d.720​

The area of a circle is area = pi x r^2

The full area = 3.14 x 20^2 = 1256 square feet.

The corner forms a 90 degree angle so the dirt area is 3/4 of a full circle.

Answer = 1256 x 3/4 = 942 square feet

Answer:

Step-by-step explanation:

942 SQUARE FEET

Answer:

180 and 181

Step-by-step explanation:

A pythagorean triple basically refers to numbers that satisfies the pythagorean theorem. This theorem states that the square of the hypotenus (a) of a right angle triangle is equal to the sum of the squares of the other two sides (b and c).

That is;

a² = b² + c²

If the shortest side is 19, the other two sides are 180 and 181.

The hypotenus is the longest side of the right angle triangle.

Check:

181 = 180 + 19

181² = 180² + 19²

32761 = 32400 + 361

32761 = 32761

Answer:

3 lines. Tangent line is defined as a line that passes through exactly 1 point in a circle. You can have a tangent line in the rightmost part, the point of intersection in the two circles, and the leftmost part.

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

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]

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.

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.

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

Answer:

B

Step-by-step explanation:

Trisha has $100. So she has to spend less than $100 or exactly 100 on her friends. The sign to represent this is ≤ ( the less than or equal to sign )

so if she has 4 friends and wants to spend x on each friend, she would spend a total of 4x on her 4 friends.

Remember that she has to spend less than or equal to $100. The equation to represent this is 4x ≤ 100
