Answer:

[tex]\huge\boxed{\sf\:x = 9}[/tex]

Step-by-step explanation:

[tex]3x = 27[/tex]

Divide both the sides of the equation by 3.

[tex]x = \frac{27}{3}[/tex]

Now, solve it.

Answer:

[tex]\huge\boxed{\sf 8 + 4\sqrt{2} \ cm }[/tex]

Step-by-step explanation:

[tex]\theta = 45 \textdegree[/tex]

opposite = 4 cm

Using tan first to find the adjacent side:

[tex]\displaystyle tan \theta = \frac{opposite}{adjacent} \\\\tan \ 45 = \frac{4}{adjacent}\\\\1 = \frac{4}{adjacent} \\\\Multiply \ 'adjacent' \ to \ both \ sides\\\\adjacent = 4 \ cm[/tex]

Finding Hypotenuse now by using Pythagorean theorem:

[tex](Hyp)^2 = (base)^2 + (perp)^2[/tex]

where base = 4, hyp = 4

(Hyp)² = (4)² + (4)²

(Hyp)² = 16 + 16

(Hyp)² = 32

Take sqrt on both sides

[tex]Hyp = 4\sqrt{2}[/tex] cm

Exact perimeter of triangle:

= base + perpendicular + hypotenuse

= 4 + 4 + 4√2

= [tex]8 + 4\sqrt{2}[/tex] cm

Step-by-step explanation:

1760 + 240 = 2000. This means 1760/2000 of them were voting in favor of Starbucks. 1760/2000 simplifies to 88/100, which is 88%.

Answer: I believe the answer is d or b

Step-by-step explanation:

The number of pizza pieces left is (x + 4) / 4. Option c

Let's assume the total number of pizza pieces is represented by 'x'.

Kevin takes 1/4 of the total pieces, which is (1/4) * x = x/4.

Keith takes one piece less than twice the number of pieces Kevin took, which is 2 * (x/4) - 1 = (2x/4) - 1 = x/2 - 1.

To calculate the number of pizza pieces left, we need to subtract the sum of Kevin's and Keith's pieces from the total number of pieces (x):

Leftover pieces = Total pieces - (Kevin's pieces + Keith's pieces)

= x - (x/4 + x/2 - 1)

= x - (3x/4 - 1)

= x - 3x/4 + 1

= (4x - 3x + 4) / 4

= (x + 4) / 4

Therefore, the number of pizza pieces left is (x + 4) / 4.

The correct option among the given choices would be (c) 1/2x + 1.

Answer:

a. Find the measure of each central angle.

The central angle of a circle = 360 °

Now Pie is cut into 10 equal sectors

Angle of each sector is given by

Angle of sector = Total central angle/number of sectors

[tex] = {360}^{0} \div 10[/tex]

[tex] = {36}^{0} [/tex]

Hence , the central angle of one slice of pie is 36°

b. If the diameter is 50 in., find the length of an arc of one of the sectors.

length of an arc of one of the sectors =

[tex] = \frac{1}{n} \times 2\pi \times r[/tex]

[tex]= \frac{1}{10} \times 2\ \frac{22}{7} \times 50[/tex]

[tex] = 31.42 \: in[/tex]

Answer: 36 degrees

Step-by-step explanation:

A circle is 360 degrees.

If you divide 360 degrees by 10, (10 sectors) you get 36.

The answer is therefore 36 degrees. (don't forget your labels!!!)

Answer:

area of circle = πr^2

just substitute 20 for r:

π(20)^2

= 400π

If the question ask for an answer in terms of pi, this is your answer. If it doesn't, simplify it further to get:

= 1256.637061 (m/cm)^2

You can round this however you like, but I would say either 3 significant figures, either 1 or 2 decimal places.

Answer:

9

Step-by-step explanation:

we can use the pythagorean theorem so (15)²= (12)² + (x)²--> (15)²-(12)²=x²

take the square root of both sides ans x=9

note! this is a special type of triangle called a 3-4-5 special right triangle because all the sides when divided by a factor of 3 will simplify down to the sides 3-4-5 (only true when the hypotheneuse is the 5 because it's the longest side of a triangle)

Answer:

[tex]k = \frac{322}{27} [/tex]

Step-by-step explanation:

x + 3 = 0 → x = - 3

25 + 4(-3)⁴ + k(-3)³ + (-3) - 11 = 13

25 + 324 - 27k - 3 - 11 = 13

349 - 27k - 14 = 13

349 - 14 - 13 = 27k

349 - 27 = 27k

322 = 27k

k = 322/27

Probabilities are used to determine the chances of events

Probability that a person selected at random is a left-handed male

From the table, the number of left-handed male is 5, and a total of 121 people were surveyed.

The probability is then calculated as:

[tex]p = \frac{5}{121}[/tex]

Hence, the probability that a person selected at random is a left-handed male is 5/121

Probability that a person selected at random is a right-handed

From the table, the number of right-handed people is 109

The probability is then calculated as:

[tex]p = \frac{109}{121}[/tex]

Hence, the probability that a person selected at random is a right-handed is 109/121

Using it's concept, it is found that the probabilities are as follows:

1. A.) 4%

2. D.) 90%

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Item 1:

Total of 121 people, 5 are left handed males, hence:

p = 5/121 = 0.0413 = 4%.

Item 2:

109 out of 121 people are right-handed, hence:

p = 109/121 = 0.9 = 90%.

Answer: y=0.25x+4

Step-by-step explanation:

Explanation:

Can we rotate the figure some angle smaller than 360 degrees and have it match up with its original image? The answer to that is "no". Any such rotation will change the image to something else. Therefore, this figure does not have any point symmetry (aka rotational symmetry).

Can we reflect one half of the figure over some line to get the other half? The answer here is also "no". The diagram has no reflectional symmetry either.

Plane symmetry is ruled out because that only applies to 3D settings.

The value of x when y is 8 is 9.75.

It is given that

y ∝ 1/x

y = k/x......(1)

Where k is a constant of proportionality

The constant of proportionality is the ratio that relates two given values.

When y =13, x=6

Means, 13 = k/6

k = 78

Putting the value of k in equation (1)

y = 78/ x

8 = 78/ x

x =9.75

Therefore, The value of x when y is 8 is 9.75.
