An angle has a measure of 150° and a terminal side that intercepts the unit circle at (x,y). What are the values of x and y?
Answer:
x = -√3 /2
y = ½
Step-by-step explanation:
x = cos 150°= -√3 /2

a calculator is listed for $110 and is on clearence for 35% off. sales tax is 7%. what is the cost of the calculator
Answer:
$76.51
Step-by-step explanation:
The price after discounting is (1.00 - .35)($110), or 0.65($110) = $71.50.
The price after 7% sales tax has been added in is
(1.00 + 0.07)($71.50) = $76.51.

vectors
p=(4,3) and q=(-2,7), find 4p -2q
Answer:
(20, -2)
Step-by-step explanation:
Given the coordinate vectors p=(4,3) and q=(-2,7),
4p - 2q = 4(4, 3)- 2(-2, 7)
4p - 2q = (16, 12) - (-4, 14)
4p - 2q = (16+4, 12-14)
4p - 2q =(20, -2)
hence the required vector is (20, -2)

What is the surface area of the rectangular prism shown by net?
The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for which the surface area is the sum of the areas of its faces. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces. This definition of surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration.

Which equation gives the volume of the sphere? V = two-thirds (27 pi) V = four-thirds (27) V = two-thirds (27) V = four-third (27 pi)
Answer:
V = four-third (27 pi)
Step-by-step explanation:
Complete question;
A sphere and a cylinder have the same radius and height. The volume of the cylinder is 27 pi feet cubed.
A sphere with height h and radius r. A cylinder with height h and radius r.
Which equation gives the volume of the sphere?
V = two-thirds (27 pi)
V = four-thirds (27)
V = two-thirds (27)
V = four-third (27 pi)
Volume of the cylinder V = πr²h
If Volume is 27pi feet cubed, hence;
27pi = πr²h
27 = r²h
Since r = h
27 = r³
r = ∛27
r = 3
Since the volume of the sphe4/3πr³re = 4/3πr³
Volume of sphere = 4/3π(27)
Volume of sphere = 4/3(27π)
Hence the correct option is V = four-third (27 pi)

B) Una empresa A gana S/ 42 758,35 en un ano. Si la empresa B gastara S/ 8774,55; tendria tantas ganancias como la primera empresa. Cual es la ganancia total de la empresa B?
Answer:
Las ganancias totales de la empresa B en dicho año fueron de $51.532,90.
Step-by-step explanation:
Dado que una empresa A gana $42.758,35 en un año, y si la empresa B gastara $8.774,55 tendría tantas ganancias como la primera empresa, para determinar cuál es la ganancia total de la empresa B se debe realizar el siguiente calculo:
Ganancias B - 8.774,55 = 42.758,35
Ganancias B = 42.758,35 + 8.774,55
Ganancias B = 51.532,90
Por lo tanto, las ganancias totales de la empresa B en dicho año fueron de $51.532,90.
A sports company wants to package a ball with a 1.5-inch radius in sets of two. They have two options: a cylinder or a square prism.The company wants to use the package that has the least amount of wasted space. The company should choose
Answer:
The Company should choose to get the cylinder packages ( V = 42.39 in³ )
Step-by-step explanation:
The volume of a cylinder of radius of circumference 1.5 in and h = 1.5*4
h = 6 in is:
V(c) = π *r²*h = π * (1.5)²*6 = π *2.25*6
V(c) = 42.39 in³
Now V(p) = Square of the base ( of side 3 in) * h
h = 6 in
V(p) = (3)²*6
V(p) = 54 in³
If we compare these two volumes we see that the volume of the cylinder is small than that of the square prism

May someone help me I kinda stuck and I would love some help it 6th-grade math!
Answer:
72
Step-by-step explanation:
first, you cut the top of the T and you multiply 12 x 3 which is 36. Then with the 4 cm on both sides, I'm assuming the middle part is also 4 (since the other side is 12) and then you multiply 9 x 4 which is also 36, then you add and get 72!

Scott measured a kitchen and made a scale drawing. He used the scale 1 inch : 5 feet. The actual
length of a countertop in the kitchen is 10 feet. How long is the counter in the drawing?
Answer:
2 inches in the drawing
Step-by-step explanation:
Because if 5 feet equals 1 inch and 5 times 2 equals 10 feet (so now we do the same to the other side) 1 times 2 and that equals to 2 inches.

Greata had a price of cloth that is 9 yards long. She cuts it into prices that are each 1/3 yard long. How many prices of cloth does Greata have now?
Given:
Length of cloth = 9 yards
Length of pieces = [tex]\dfrac{1}{3}[/tex] yards each
To find:
The number of pieces of cloths after cutting.
Solution:
Let n be the number of required pieces.
Length of each piece is [tex]\dfrac{1}{3}[/tex] yards. So, the length of n pieces is [tex]\dfrac{1}{3}n[/tex] yards.
The length of the whole cloth is 9 yards. So, [tex]\dfrac{1}{3}n[/tex] yards must be equal to 9 yards.
[tex]\dfrac{1}{3}n=9[/tex]
Multiply both sides by 3.
[tex]n=9\times 3[/tex]
[tex]n=27[/tex]
Therefore, the Greata have 27 pieces of cloths.
