Answer:
C
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{10}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2x = 10 ( divide both sides by 2 )
x = 5 → C

Which is the better buy? 16 cards for $12.20 OR 14 cards for $10.90
Answers
Answer:
The better buy is 16 cards for $12.20 because
Step-by-step explanation:
You need to find the individual price for each card in the packet. So first lets do 16 cards for $12.20, you divide $12.20 by 16 to get the price of one card. 12.2/16=0.7625, or about $0.76. Next we do $10.90 divided by 14, 10.9/14=0.7785, or about $0.78, which means 16 cards for $12.20 is the better buy!
The restaurant manager wants to find how much they are spending for pies and cakes. Last week they payed 204$ for 12 pies and 8 cakes
Answers
Answer: See explanation
Step-by-step explanation:
Your question isn't complete and I couldn't get the exact question online but let's reframe it and solve it.
The restaurant manager wants to find how much they are spending for pies and cakes. Last week they payed 204$ for 12 pies and 8 cakes. This week, they paid $129 for 5 pies and 7 cakes.
Let's say the cost of pies is x
Let's say the cost of cake is y.
We'll then use the information given to make an equation which will be:
Last week they payed 204$ for 12 pies and 8 cakes. This will be:
12x + 8y = 204........ i
This week, they paid $129 or 5 pies and 7 cakes. This will be:
5x + 7y = 129 ........... ii
Therefore,
12x + 8y = 204........ i
5x + 7y = 129 .......... ii
Multiply equation i by 5
Multiply equation ii by 12
60x + 40y = 1020 ....... iii
60x + 84y = 1548 ........ iv
Subtract iii from iv.
44y = 528
y = 528/44
y = 12
The cost of cake is $12.
From equation i,
12x + 8y = 204
12x + 8(12) = 204
12x + 96 = 204
12x = 204 - 96
12x = 108
x = 108/12
x = 9
The cost of pies is $9.

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?
Answers
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.

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?
Answers
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.

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)
Answers
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)

Answers
Answer:
6(base) x 3.5(Height) = 21, 21 divided by 2 (x 1/2) = 10.5
10.5(area of triangle) x 7.75(width) = 81.375
Formula of an area of a triangle:
BH x 1/2
Base x Height x 1/2(basically just dividing by 2)
Now the base:
1.5 x 7.75 x 6 = 69.75
Now let's add the two given volumes:
81.375+ 69.75 = 151.125 ft^3 is your answer.

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
Answers
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
What is the surface area of the rectangular prism shown by net?
Answers
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.
