Which revolution will generate this hemisphere?
Rotate a semicircle 180° about its diameter.
Rotate a circle 180° about a diameter.
Rotate a trapezoid 180° about one of its bases.
None of the other answers are correct
Rotate a rectangle 180° about one of its sides
Answer:
Rotate a semicircle 180° about its diameter
Step-by-step explanation:
For common figures, the shape of a figure that revolves about a line which is at the base of the figure to give a 3 dimensional shape is the shape of the cross section of the 3 dimensional figure when the angle of revolution is 180° and half the shape of the cross section of the formed 3 dimensional figure, when the angle of revolution is 360°
The cross section of an hemisphere is a semicircle, therefore, the shape of an hemisphere is formed by rotating a semicircle 180° about the diameter (which is the straight line at the "base") of the semicircle
Therefore;
The correct option that gives the revolution that will generate the hemisphere is;
Rotate a semicircle 180° about its diameter.
Find the measure of arc BC
Answer:
100°
Step-by-step explanation:
is 25% of the circle
Answer:
BC = 100°
Step-by-step explanation:
The chord- chord angle BDC is half the sum of the arcs intercepted by the angle and its vertical angle, that is
[tex]\frac{1}{2}[/tex] ( BC + AE) = 85° ( multiply both sides by 2 to clear the fraction )
BC + AE = 170°
BC + 70° = 170° ( subtract 70° from both sides )
BC = 100°

Find the missing value of x and y.
Step-by-step explanation:
tan 60 = 21 ÷ y
1.73 = 21 ÷ y
y = 21 ÷ 1.73
y = 12.14
tan 30 = x÷ 12
0.6 x 12 = x
x = 7.2
3/7% of a quantity is equal to what fraction of the quantity?
Answer:
3/700
Step-by-step explanation:
Let
x = the quantity
3/7% of x
= 3/7 ÷ 100 * x
= 3/7 × 1/100 * x
= (3*1)/(7*100) * x
= 3/700 * x
= 3/700x
3/7% of a quantity = 3/700 of the quantity

Solve for Y (geometry)
Answer:
[tex]y=10[/tex]
Step-by-step explanation:
We know that the sum of these two angles is 180 degrees. Why? Imagine if the horizontal line was perfectly horizontal. There would be two 90 degree angles, one at each intersection of the vertical lines. If the rotate the line, we haven't magically removed or added degrees, so we know it is still 180 degrees.
Hence, the equation is:
[tex]180=120+6y\\60=6y\\\bold{y=10}[/tex]

An isosceles right triangle is inscribed in a circle. The hypotenuse of the triangle is the diameter of the circle. Write a function f in terms of x that represents the area of the shaded region. Leave your answer in terms of π.
9514 1404 393
Answer:
f(x) = (π-2)x^2/4
Step-by-step explanation:
The area of the triangle is ...
A = 1/2(x)(x) = (1/2)x^2
The hypotenuse of the triangle is x√2, so the radius of the circle is x/√2. That means the area of the semicircle is ...
A = 1/2πr^2 = (π/2)(x/√2)^2 = (π/4)x^2
The shaded area is the difference between the semicircle area and the triangle area.
f(x) = (π/4)x^2 -(1/2)x^2
f(x) = (π-2)x^2/4

Which expression is NOT a polynomial?
Answer:
The last expression.
Step-by-step explanation:
The last expression is not a polynomial because x is in the denominator of the second term.
Answer:
[tex]4x^2+\frac{5}{x} -6[/tex]
Step-by-step explanation:
A rule for polynomials, is that if they have variables, the powers should be positive whole numbers. Basically, this means you cannot divide by a variable, but in option 4, second term, you are dividing 5 by x, which is the same as[tex]5*x^{-1}[/tex]. This means you are not raising the variable to a positive power, which means the whole 4th option is not a polynomial.

Tony is the staff manager of a movie theater, and he is trying to decide which shifts should have the greatest number of employees on staff. Over the course of a week, Tony recorded how many customers appeared during each shift, the results of which can be seen in the graph below.
A bar graph titled Customers in One Week has Shift Start Time on the x-axis and Number of customers on the y-axis. 10 a m, 121; 1 p m, 156; 4 p m, 378; 7 p m, 671; 10 p m, 458.
Tony wants the distribution of his employees to match the distribution of the customers. If Tony has 230 total employees, how many should he assign to the 1:00 p.m. shift?
a.
15
b.
20
c.
68
d.
156
Answer:
B is right I can confirm since i got a 100% on edg
Step-by-step explanation:
The manager should assign 20 people at 1 p. m.
What is percentage?A relative value indicating hundredth parts of any quantity.
If we look at the data.
The total number of customers =1784
At 1 pm, No. of Customers =156
So, 156 is 8.74% of 1784
If there are 230 employees, then at 1 pm the manage should assign
=[tex]8.74[/tex] % of 230
= 20.10
= 20 employees

Five people buy individual insurance policies. According to the research, the probability of each of these people not filing a claim for at least 5 years is 2/3 . What is the probability that all 5 have not filed a claim after 5 years?
Answer:
Probability = 0.135
Step-by-step explanation:
Prob (one person doesn't file claim) = 2 / 3 = 0.67
Prob (5 people don't file claim) = p1 doesn't & p2 doesn't ...& p5 doesn't , ie = 0.67 x 0.67 x 0.67 x 0.67 x 0.67
= 0.67^5
= 0.135
