Answer:
1440°
Step-by-step explanation:
Formula for sum of the measures of the interior angles of a polygon is given as:
[tex] (n-2)\times 180°\\
= (10-2)\times 180°..(plug\: n = 10)\\
= 8\times 180°\\
= 1440°

What is the value of s? I'll mark first correct answer brainliest.
Answer:
s = 11.
Step-by-step explanation:
To find the value of 's', we can first use the Supplementary Angles theorem. If '12s' is the measure of the angle outside of the triangle, the angle inside the triangle must be equivalent to '180-12s'.
Since the sum of all of the angles of the triangle must be 180°, we can set up an equation to solve for 's':
180 = 45 + 10s - 23 + 180 - 12s (Subtract both sides by 180)
Simplify:
0= 45 + 10s - 23 - 12s (Subtract both sides by 45, and add 23 to both)
-22 = 10s - 12s
-22 = -2s (Divide both sides by -2)
s = 11.

cos(3x) = 1
1. Using an appropriate inverse trigonometric expression, write an equation that defines the value of 3x
2. Solve this equation to find all possible values of the angle 3x
3. Use algebra to find all values of x between 0 and 2pi that satisfy this equation
Step-by-step explanation:
cos(3x) = 1
3x = 0 + 2kπ
x = 0 + 2kπ/3
x = 0, 2π/3, 4π/3, 2π
What MUST be true when adding and subtracting numbers in scientific notation?
This might help you with your question 2 numbers inside of scientific notation have to be manipulated in order for their own foundations to have the same exact exponent
To be added or subtracted, two numbers in scientific notation must be manipulated so that their bases have the same exponent--this will ensure that corresponding digits in their coefficients have the same place value.

\frac{h^{2}-1 }{h+3} when h=5
Answer:
The answer is 3.
Step-by-step explanation:
You have to substitute h = 5 into the fraction :
[tex] \frac{ {h}^{2} - 1}{h + 3} [/tex]
Let h = 5,
[tex] = \frac{ {5}^{2} - 1}{5 + 3} [/tex]
[tex] = \frac{25 - 1}{8} [/tex]
[tex] = \frac{24}{8} [/tex]
[tex] = 3[/tex]
Answer:
Step-by-step explanation:
[tex]\frac{h^2-1}{h+3 } \\when~h=5\\\frac{5^2-1}{5-1} =\frac{24}{4} =6[/tex]

The cereal box shown below is a rectangular prism. Find the surface area of the cereal box.
Answer:
Surface area is found:
Surface Area = 1700 cm²
Step-by-step explanation:
(The cereal box is shown in the ATTACHMENT)
The surface area of a rectangular prism can be found by added the areas of all 6 sides of the rectangular prism.
L = length = 20 cm
H = height = 30 cm
W = Width = 5 cm
Side 1:A(1) = L×H
A(1) = 20×30
A(1) = 600 cm²
Side 2:As the measurements of the side at the back of side 1 has the same measurement of side 1. then:
A(2) = 600 cm²
Side 3:A(3) = L×W
A(3) = 20×5
A(3) = 100 cm²
Side 4:As the measurements of the side at the back of side 4 has the same measurement of side 4. then:
A(4) = 100 cm²
Side 5:A(5) = H×W
A(5) = 30×5
A(5) = 150 cm²
Side 6:As the measurements of the side at the back of side 5 has the same measurement of side 5. then:
A(6) = 150 cm²
Surface Area:Adding areas of all the sides
A(1) + A(2) + A(3) +A(4) + A(5) + A(6) = 600 + 600 + 100 +100 + 150 +150
Surface Area = 1700 cm²
Answer:
580
Step-by-step explanation:
Area of a rectangle = length x width
3x20=60
2x60=120
The bottom and the top are both 3 by 10 rectangles
120+60+400=580

4x^2+2x-42/4x /(x-3)
Answer:
(x (8 x^2 - 20 x + -33))/(2 (x - 3))
Step-by-step explanation:
Simplify the following:
4 x^2 + 2 x - (42 x)/(4 (x - 3))
The gcd of 42 and 4 is 2, so 42/4 = (2×21)/(2×2) = 2/2×21/2 = 21/2:
4 x^2 + 2 x - x/(x - 3) 21/2
Put each term in 4 x^2 + 2 x - (21 x)/(2 (x - 3)) over the common denominator 2 (x - 3): 4 x^2 + 2 x - (21 x)/(2 (x - 3)) = (8 (x - 3) x^2)/(2 (x - 3)) + (4 (x - 3) x)/(2 (x - 3)) - (21 x)/(2 (x - 3)):
(8 x^2 (x - 3))/(2 (x - 3)) + (4 x (x - 3))/(2 (x - 3)) - (21 x)/(2 (x - 3))
(8 (x - 3) x^2)/(2 (x - 3)) + (4 (x - 3) x)/(2 (x - 3)) - (21 x)/(2 (x - 3)) = (8 (x - 3) x^2 + 4 (x - 3) x - 21 x)/(2 (x - 3)):
(8 x^2 (x - 3) + 4 x (x - 3) - 21 x)/(2 (x - 3))
Factor x out of 8 (x - 3) x^2 + 4 (x - 3) x - 21 x, resulting in x (8 (x - 3) x^(2 - 1) + 4 (x - 3) - 21):
(x (8 x^(2 - 1) (x - 3) + 4 (x - 3) - 21))/(2 (x - 3))
2 - 1 = 1:
(x (8 x (x - 3) + 4 (x - 3) - 21))/(2 (x - 3))
8 x (x - 3) = 8 x^2 - 24 x:
(x (8 x^2 - 24 x + 4 (x - 3) - 21))/(2 (x - 3))
4 (x - 3) = 4 x - 12:
(x (4 x - 12 + 8 x^2 - 24 x - 21))/(2 (x - 3))
Grouping like terms, 8 x^2 + 4 x - 24 x - 21 - 12 = 8 x^2 + (-24 x + 4 x) + (-12 - 21):
(x (8 x^2 + (-24 x + 4 x) + (-12 - 21)))/(2 (x - 3))
4 x - 24 x = -20 x:
(x (8 x^2 + -20 x + (-12 - 21)))/(2 (x - 3))
-12 - 21 = -33:
Answer: (x (8 x^2 - 20 x + -33))/(2 (x - 3))

Based on the sample of 8th graders in the table, how many of the 350 students in 8th grade will like Pop/Rock as their favorite type of music?
Answer:
168
Step-by-step explanation:
Out of the 12 + 7 + 6 = 25 students sampled, 12/25 = 48% students liked Pop/Rock so 48% of 350 = 168 students is the answer.
Answer: 168 students
Step-by-step explanation:
12 + 7 + 6 = 25 so if we add all the numbers we get 25 then
we put it as 12/25 which is
48% students liked Pop/Rock
so then we do 48% of 350 or divide and get
168 students

HELP IMPORTANT In one U.S. city, the taxi cost is $2 plus $0.50 per mile. If you are traveling from the airport, there is an additional charge of $6.00 for tolls. How far can you travel from the airport by taxi for $38.00?
Answer:
60 miles
Step-by-step explanation:
f(x) = 2 + 0,5 * m + 6
38 = 2 + 0,5 * m + 6
38 = 8 + 0,5 * m
30 = 0,5 * m
m = 60 miles

Ekene was curious if sample range was an unbiased estimator of population range. She placed ping pong balls
numbered from 0 to 32 in a drum and mixed them well. Note that the range of the population is 32.
She then took a random sample of 5 balls and calculated the range of the sample. She replaced the balls and
repeated this process for a total of 50 trials. Her results are summarized in the dotplot below, where each dot
represents the sample range from a sample of 5 balls.

Sample range appears to be a biased estimator since it consistently underestimated the population
Answer:

In this exercise we have to use, in addition to the knowledge of statistics, the graph informed in the exercise in this way, we can say that:
Letter A
When we look at the graph, the maximum points are at 21 and 31, while the samples ranges appear to be centered below 32, that is we can say that the letter A is more appropietate.
