A newspaper and magazine cost 220 together the newspaper cost 140 less than the magazine, then the cost of magazine is 180 and the cost of newspaper is 40.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
A newspaper and magazine cost 220
the newspaper cost is 140 less than the magazine
Let x be the cost of magazine
x-140 is the cost of newspaper
x+x-140=220
2x-140=220
Add 140 on both the sides
2x=220+140
2x=360
Divide both sides by 2
x=180
and x-140=180-140=40
Hence, the cost of magazine is 180 and the cost of newspaper is 40.

Lucy bought a fish tank shaped like a rectangular prism for her new betta fish. The tank holds 2,244 cubic inches of water. It is 12 inches long and 11 inches wide.
Answer:
The length of the fish tank is 17 inches.
Step-by-step explanation:
The volume of a rectangular prism is length × breadth × height.
You already know the volume, breadth, and height, so you can find the length.
Length = 2244 ÷ 12 ÷ 11
= 17 inches
The height of the tank is 17 inches.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given that,
The shape of the fish tank is rectangular prism.
The formula to calculate the volume of the rectangular prism is,
Volume = Length × Width × height
Given,
Volume of the tank = 2,244 cubic inches
Length = 12 inches
Width = 11 inches
Let x be the height.
Substituting the given values,
2,244 = 12 × 11 × x
x = 2244 / (12 × 11)
x = 2244 / 132
x = 17 inches
Hence the height of the tank is 17 inches.

The ratio of boys to girls taking geometry this year is 27:31. If 246 students are ebrolled in geometry this year, approximately how many of them are boys and how many of them are girls?
Answer:
115 boys
131 girls
Step-by-step explanation:
Given data
The given ratio= 27:31
The sum of the ratio = 27+31= 58
The total number of students taking geometry= 246
Let us apply the part to all method
let the number of boys be x
27/58= x/246
cross multiply
58*x= 246*27
58x=6642
x= 6642/58
x=114.5
Hence the number of boys is 115
Thefore, the number of girsl= 246-115= 131

Answer:
D
Step-by-step explanation:
The volume (V) of a cone is calculated as
V = [tex]\frac{1}{3}[/tex] πr²h ( r is the radius and h the height )
Here V = 226 and r = 12 ÷ 2 = 6 , then
[tex]\frac{1}{3}[/tex]π × 6²h = 226 ( multiply both sides by 3 to clear the fraction )
3.14 × 36h = 678
113.04h = 678 ( divide both sides by 113.04 )
h = [tex]\frac{678}{113.04}[/tex] ≈ 6 m ( to the nearest metre )

In OPQ, the measure of Q=90°, OP = 96 feet, and PQ = 23 feet. Find the measure
of 20 to the nearest degree.
Answer:
[tex]O = 14^\circ[/tex]
Step-by-step explanation:
Given
[tex]\angle Q = 90[/tex]
[tex]OP = 96[/tex]
[tex]PQ = 23[/tex]
Required
Find [tex]\angle O[/tex] to the nearest degree
To calculate O, we make use of:
[tex]sin(O) = \frac{PQ}{PO}[/tex] --- See attachment for triangle
[tex]sin(O) = \frac{23}{96}[/tex]
[tex]sin(O) = 0.2396[/tex]
Take arcsin of both sides
[tex]O = sin^{-1}(0.2396)[/tex]
[tex]O = 14^\circ[/tex] -- approximated
