If the smallest angle of rotation for a regular polygon is 18, how many sides does polygon have?
10
12
20
24
Answers
Answer: There are 20 sides of a given regular polygon.
Step-by-step explanation:
To calculate the sides of a regular polygon, we use the equation:
[tex]\text{Number of sides}=\frac{360^o}{\text{Smallest angle of rotation}}[/tex]
We are given:
Smallest angle of rotation = [tex]18^o[/tex]
Putting values in above equation, we get:
[tex]\text{Number of sides}=\frac{360^o}{18^o}\\\\\text{Number of sides}=20[/tex]
Hence, there are 20 sides of a given regular polygon.

20

Jen's test grades for this term are 85,92, and 95. She wants to have a test average of at least 90 for this term, and she will have one more test. What is the lowest score that she can get to have a test average of at least 90?
Answers
Answer:
Step-by-step explanation:
(85+92+95+x)/4
=90
(272+x)/4
=90
90×4=360
272+x=360
x=360-272=88

Answer: The formula for sector area is simple, multiply the central angle by the radius squared, and divide by 2: Sector Area = r² * α / 2. So you want to do that for every problem like this
Step-by-step explanation:s
=========================================================
Explanation:
Let's ignore the area of the shaded slice for now. Instead, we'll find the area of the full circle
We plug in the radius r = 1 to find that
A = pi*r^2
A = pi*1^2
A = pi
The exact area of that full circle is pi square meters. You can think of an actual pie (the baked pastry, not the constant) with this area as a way to help conceptualize things.
If we wanted the whole circle, then we'd say pi is the answer. However, we only want a slice of that circle. The fractional amount 66/360 represents the slice we want. This fraction reduces to 11/60 after you divide both parts by 6. If you were to cut the pizza up into 60 slices, then you would shade 11 of them in to represent the green area.
Multiply 11/60 with the area pi to get the final answer 11pi/60
This answer is exact in terms of pi
To get an approximate value, you could replace pi with 3.14 to get 11pi/60 = 11*3.14/60 = 0.57567 meaning the green shaded area is roughly 0.57567 square meters. Use more decimal digits of pi to get a more accurate shaded area.
Does f(x) = - 3x² + 6x - 4 have a maximum or
minimum? Find the value
Answers
Answer:
Maximum value.
it = -1.
Step-by-step explanation:
Maximum value as the coefficient of x^2 is negative.
To find this value we convert to vertex form:
y = -3x^2 + 6x - 4
y = -3(x^2 - 2x) - 4
y = -3[(x - 1)^2 - 1] - 4
y = -3(x - 1)^2 + 3 - 4
y = =3(x - 1)^2 - 1
Minimum value = -1.

Line A has a slope of 3/2 and passes through the point (3, 3). Line B has a slope of – 1/3 and passes through the point (-4, -2). At what point does line A intersect line B? Line Aintersects line B at the point ( , ).
Answers
Answer:
The lines meet at (-1, -3)
Step-by-step explanation:
Line A :
[tex](x_1, y_1) = (3, 3) \ ; \ slope, \ m_A = \frac{3}{2}\\\\Equation \ of \ line \ A : (y - 3) = \frac{3}{2}(x - 3)[/tex]
[tex]2(y - 3) = 3(x-3)\\2y - 6 = 3x - 9\\2y = 3x - 9 + 6\\2y = 3x -3[/tex]
Line B :
[tex](x_2,y_2) = (-4, -2) \ ; \ slope , m_B = -\frac{1}{3}\\\\Equation \ of\ line \ B: (y -(-2)) = -\frac{1}{3}(x -(-4))[/tex]
[tex]3(y + 2) = -1(x+4)\\3y + 6 = -x -4\\3y = -x - 4 - 6 \\3y = -x - 10[/tex]
Solve for x and y from the linear equation to find where line A and line B meets :
2y = 3x - 3 => 3x - 2y = 3 ------- (1)
3y = -x - 10 => -x = 3y + 10
=> x = - 3y - 10 --------(2)
Substitute (2) in (1) : => 3(- 3y - 10) - 2y = 3
-9y - 30 -2y = 3
-11y = 3 + 30
-11y = 33
y = -3
Substitute y in (2) : => x = -3 (-3) - 10 = 9 - 10 = -1

slope = 4, point (3,-2) is on the line
Answers
Answer:
y = 4x + b
Step-by-step explanation:
We know that (3, -2) is on this line. So 3 = m(-2)+b.
This leaves us with two variables the slope (m) and the y intercept (b).
But wait a minute, the slope is given to us since it says slope = 4.
Our equation is now, 3 = 4(-2)+b
3 = -8 + b
b = 11.
Our final equation is now y = 4x + b.
(y,x) is a point on this line.

Find the word or phrases that best complete the sentence intersecting planes ___ intersect in exactly one point
Answers
Answer:
never
Step-by-step explanation:
Intersecting planes are planes that intersect along a given line.
To explain this better, consider the following definitions:
i. A point: This is denoted by a dot and it is a location marked on a space or a plane.
ii. A line: This is the distance between two points. It is one-dimensional.
iii. A plane: This is a two-dimensional, flat surface with no thickness formed by points and extends infinitely.
Therefore, since intersecting planes intersect along a line, it is not possible that they intersect in exactly one point given that a line is the distance between points.

Since out of 100 students who appeared in grade VIII annual examination of Ram Janaki Secondary School, 60 passed in mathematics, 50 in science and 20 students passed in both subjects, to determine how many failed in both subjects the following calculation must be performed:
(100 - 20) - (60 - 20) - (50 - 20) = X
80 - 40 - 30 = X
40 - 30 = X

Silas has 5 1/4 cups of flour. He uses 3 1/2 cups to bake bread, then he borrows another 2 cups from his neighbor. He wants to bake cookies, which take 2 3/4 cups of flour. Does he have enough? How much will he have left over, or how much more does he need?
Answers
Answer:
He has enough to bake the cookies with 1 cup of flour left over.
Step-by-step explanation:
5.25 cups to start - 3.5 for the bread = 1.75 remaining
1.75 cups + 2 cups from neighbors = 3.75 cups
3.75 - 2.75 for cookies = 1 cup left over.

Sunny and Rashika collect stamps. Sunny has collected 3 times as many stamps as Rashika. Together, they have 304 stamps. How many stamps does each person have? Show your work.
Answers
Answer:
Sunny = 228 stampsRashika = 76 stampsStep-by-step explanation:
Sunny has collected 3 times the stamps that Rashika has collected but in total they have both collected 304 stamps.
Assume that Rashika has x stamps. This would mean that Sunny has (3 * x) or 3x stamps.
In an equation this would be:
x + 3x = 304
4x = 304
x = 304/4
x = 76 stamps
Rashika has 76 stamps.
Sunny has 3 times that number:
= 76 * 3
= 228 stamps
