For a school fundraiser, Tory sold 28 bags of popcorn and 40 candy bars and made $282. Jake sold 17 bags of popcorn and 20 candy bars and made $160.50.
Write a system of equations which represents this situation.
A. 28p + 17p and 40c + 20c = 160.50
B. 28p + 20c = 282 and 17p + 40c = 160.50
C. 28p + 40c = 282 and 17 + 20c = 160.50
D. 28p + 40c + 17p + 20c = 282 + 160.50
How many solutions does this system of equations have?
Answer:
One solution.
A system of linear equations has one solution when the graphs intersect at a point.

An empty rectangular tank measures 60 cm by 50 cm by 56 cm. It is being filled with water flowing from a tap at a rate of 8 liters per minute. How long will it take to fill up the tank? (1 liter = 1000 cm3)
Answer:
21 min
Step-by-step explanation:
V = lwh
V = 60(50)(56) = 168000 cu. cm
8 liters = 8000 cu cm

A cone has a volume of 47.1 cm³ and a radius of 3 cm what is its height?
Radius of cone ( r ) = 3 cm,
Curved surface area of a cone= 47.1 cm²
Curved surface area of a cone= πrl
47.1 = πrl
47.1 = 3.14 × 3 × l
l = 47.1 / (3.14 × 3)
l = 15.7 / 3.14= 1570/314= 5 cm
slant height (l) = 5 cm
Height of a cone (h) = √(l²) - (r²)
h = √ 5² -3²
h = √ 25 - 9 = √ 16 = 4 cm
h = 4 cm
Volume of cone= ⅓(πr²h)
= ⅓(3.14 × 3 × 3 × 4)
= 3.14 × 12= 37.68 cm³
Hence, the volume of a cone is 37.68 cm³.

Roberto earns $6.50 per hour. He worked 32 hours at the regular rate, 8 hours at a time and a half, and 8 at double time. How much did he earn?
Answer $390
Step-by-step explanation:
Answer:
$390
Step-by-step explanation:
First Roberto works 32 hours at 6.50 per hour. At that time, he earn 32*6.5 = $208. Then he works 8 hours at a time and a half. This means that his pay rate is 50% more, or 6.5*1.5 = $9.75 per hour. Since he worked 8 hours at this pay rate, he earns 8*9.75 = $78. And then he works 8 hours double time. This means his pay rate was doubled during that duration. 6.5*2 = 13, 13*8 = $104.
Total: 208 + 78 + 104 = $390

Answer:
1) x=3, y=-3
Step-by-step explanation:
10x + 7y = 9 —— (1)
-4x -7y = 9 —— (2)
(1) + (2)
6x = 18
x = 18/6
x = 3
put x=3 in (1)
10(3) + 7y = 9
30 + 7y = 9
7y = 9 - 30
7y = -21
y = -21/7
y = -3

A 1kg book is lifted 2m. How much work was done?
Answer:
work= force ×distance
force= mass × acceleration due to gravity
mass= 1kg
acceleration=10
Force=1×10=10N
Work=10×2=20joules
The work done is 20 joule.
What is Work done?
It should be converted to energy in order to move an object. Energy can be transferred by the use of force. Work done refers to the amount of energy used by a force to move an object.
Given:
mass, m= 1 Kg
So, force = mg = 1 x 10 = 10 N
and, displacement = 2m
Now, work done= force x displacement
= 10 x 2
= 20 Joules.
Hence, the work done is 20 joule.

If flx) = 2x – 6 and g(x) = x-2x?, find each value.
Answer:
The question is not correct. you have two linear functions. do you want to know their intersection point?
Step-by-step explanation:
[tex]f(x)=2x-6\\[/tex]
[tex]2x-6=0[/tex]
[tex]2x=6[/tex]
[tex]\frac{2x}{2} =\frac{6}{2\\}[/tex]
x=3
Then you just plug into g(x)
[tex]g(x)=x-2x[/tex]
[tex]g(x)=3-2(3)\\[/tex]
[tex]g(x)= 3-6[/tex]
So,
