Answer:
20 cm
Step-by-step explanation:
5n × 3n = 2×120
15n²=240
n²=240/15 =16
n=√16 = 4
base = 5× 4 = 20
line one b=h*5/3
line two b*h/2=120
let's substitute b in line two with the righthand side of line one
(h*5/3)*h/2=120
h²*5/6=120
h²=(120/5)*6
h²=144
h=12
(the negative solution of the root is ignored, bc h is some distance. distances are never negative)
let's plus 12 into line two, in the place of h. this will give us b
b*12/2=120
b*6=120
b=20
h=12 and b=20 are in the right ratio (note that both are multiples of 4, 12=4*3 and 20=4*5)
and 12*20/2 = 120
everything works out just nicely

the drama club spent $8.50 per person on food for cast party. the total cost of the food was $229.50. how many people were at the cast party
If the drama club spent $8.50 per person on food, and if the total cost of food was $229.50. How many people were at the cast party?
To find how many people are there, we need to divide $229.50 to $8.50.
$229.50 ÷ $8.50 = 27
Thus there are 27 people at the party.Answer:
27 people
Step-by-step explanation:
229.50/8.50=27

Collin needs to fix his broken air conditioner unit. He decides to call some mechanics to see what it might cost to get the unit repaired. Let’s x represent the number of hours and let y represent the total cost.
Company A: y = 25x + 20
company B: y = 20 + 45
it will take ____________ hours for the cost to be the same for both companies
5 hours if there was supposed to be an x after 20 on the second equation
It will take 5 hours for the cost to be the same for both companies.
What is an equation?Two algebraic expressions having the same value and symbol '=' in between are called an equation.
Collin needs to repair his malfunctioning air conditioner.
He makes the decision to phone a few technicians to find out how much it would cost to fix the device.
Let x stand for the number of hours and y for the overall expense.
Company A: y = 25x + 20
company B: y = 20x + 45
To find the number of hours it will take for the cost to be the same for both companies, we need to solve the equation:
25x + 20 = 20x + 45
Simplifying the equation, we get:
5x = 25
x = 5
Therefore, x = 5

Answer: a) Surface Area : 488 [tex]cm^{2}[/tex]
Volume : 672 [tex]cm^{3}[/tex]
b) Surface Area
c) Volume
Step-by-step explanation:
The object given is a cuboid. A cuboid has 6 sides.
To calculate the surface area and volume, we need the dimensions of the cuboid which are the length(l), breadth(b), and height(h).
According to the image given, l = 14 cm, b = 8 cm, and h = 6 cm.
a) Surface Area:
The formula for the surface area of a cuboid is = 2*((l*b)+(l*h)+(b*h))
Therefore, the surface area = 2*((14*8)+(14*6)+(8*6)) = 488 [tex]cm^{2}[/tex]
The area is always denoted as [tex]cm^{2}[/tex]
Volume:
The formula for volume of a cuboid is = l*b*h
Therefore, the volume = 14*8*6 = 672 [tex]cm^{3}[/tex]
The area is always denoted as [tex]cm^{3}[/tex]
b) Plating is done to usually protect the surface area of an Object. Therefore the answer is Surface Area.
c) If the brick is made of concrete, it means that the whole space occupied by the brick consists of concrete. Therefore volume is the right option.

The formula to find out the volume of a rectangular prism is V = l × b × h where V is the volume , l = length , b = breadth & h = height.We're provided the figure of trapezium in the second attachment. The formula to fInd out the area of trapezium is A = [tex] \tt{ \frac{1}{2} h(a + b)}[/tex] where a and b are the opposite parallel sides and h be the height of a trapezium.[tex] \large{ \tt{❃ \: SOLUTION}} : [/tex]
In the first picture , we're provided - Length ( l ) = [tex] \frac{7}{4} [/tex] cm , breadth ( b ) = [tex] \frac{3}{2} [/tex] cm and height ( h ) = [tex] \frac{1}{2} [/tex] cm. Now, plug these known values and them find out the volume of given rectangular prism.[tex] \large{ \tt{❁ \: VOLUME \: OF \: RECTANGULAR \: PRISM \: ( \: V \: ) = l \times b \times h}}[/tex]
[tex] \large{ {⟶ \: \frac{7}{4} \times \frac{3}{2} \times \frac{1}{2} }}[/tex]
To multiply one fraction by another , multiply the numerators for the numerator and multiply the denominator for its denominator and reduce the fraction obtained after multiplication into lowest term if possible.[tex] \large{ ⟶ \frac{7 \times 3 \times 1}{4 \times 2 \times 2} }[/tex]

Answer:
1)
V = l * w * h
7/4 * 3/2 * 1/2 = 21/16 cm^3
2)
A = a+b ÷ 2 * h
6 + 4 = 10 ÷ 2 = 5
5 * 3 = 15 ft^2
