Answer:
Step-by-step explanation:
Area A = 1/2 bh
36a^2b^4 = 1/2 × (12ab)h
Cross multiply
72a^2b^4 = 12abh
Dividing by 12ab
h = (72a^2b^4)/12ab
h = 6ab^3
The spring .2m far when it is compressed on being supported by a mass of 10kg.
Given: Mass of 30 kg which compresses spring by 0.6m
To find: The compression of the spring when it is supported by a mass of 10 kg
Concept: Compression springs are coiled springs that hold mechanical energy in a compressed state. When these springs are subjected to compressive loads, they compress and shorten, capturing and storing significant potential force.
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
By using unitary method,
10 is 3 times less than 30.
so, 30/3=10
Also applying the same proportion over the lengths compressed,
we get, 0.6/3=.2

Answer:
(y-6)/6 = x
Step-by-step explanation:
y+4x=10x-6
Subtract 4x from each side
y+4x-4x=10x-4x-6
y = 6x-6
Add 6 to each side
y +6 = 6x-6+6
y+6 = 6x
Divide by 6
(y-6)/6 = 6x/6
(y-6)/6 = x
Answer:
option d x^2 + 8x
Step-by-step explanation:
area of rectangle = l×b
=x×(x+8)
=x^2+8x
59° + 81°+ x° = 180°
140° + x° = 180°
x = 40°
