Answer :
x = 53.85
Step by step explanation:
If 78% of x (some numbers) is equal to 42, then we must set this as an equation to find it.
1) Rewriting 78% as a fraction and considering that when we say 78% of some number (x) we mean a product.
78% = 78/100 ➡️ 78/100x = 42
2) Then we can go on :
100 * 78/100x = 42 * 100
78x = 4200
78x/78 = 4200/78 ➡️ x = 53.85
3) Alternatively, simply dividing 42 by 0.78 (78%) would come to the same result :
42/0.78 = 53.85
Answer:
<em>length</em><em> </em><em>of</em><em> </em><em>hypotenuse</em><em> </em><em>=</em><em> </em><em>10</em><em> </em><em>ft</em><em>.</em>
Step-by-step explanation:
by pythagorus theorem,

( where, h = hypotenuse, b = base , h = height )
so,
=》

=》

=》

=》

=》

hence, hypotenuse = the 10 feet.

Answer:
60
Step-by-step explanation:
60 times 2 is 120 plus 24 is 144
The least common denominator is 420
<h3>How to find the least common denominator?</h3>
The expressions are given as:
11/70 and 7/60
Factorize the denominator of the fractions.
So, we have
70 = 7 * 10
60 = 6 * 10
Multiply the factors
LCD = 6 * 7 * 10
Evaluate
LCD = 420
Hence, the least common denominator is 420
