Answer:
Simplified: 40
Step-by-step explanation:
To simplify this, we need to first separate the terms in this expression. There is a property of exponents that says: We can do this same thing to simplify this expression. Next, we can simplify each of these terms.
simply becomes 4. In the other term, the
simply cancel each other and leave the 10. This means that we're left with 4*10, which is 40
Answer:
l = 2.25 cm
Step-by-step explanation:
given l is inversely proportional to w² then the equation relating them is
l = ← k is the constant of proportion
(i)
to find k use the condition w = 1.5 , l = 16 , then
16 = =
( multiply both sides by 2.25 )
36 = k
l = ← equation of proportion
(ii)
when w = 4 , then
l = =
= 2.25 cm
Answer:
<h2>0.67</h2>Step-by-step explanation:
Distribute 5 through the parentheses
Distribute 4.7 through the parentheses
Move ' 4.7 y ' to L.H.S and change it's sign
Move constant to R.H.S and change it's sign
Collect like terms
Calculate
Divide both sides of the equation by 0.3
Calculate
