Answer:
Step-by-step explanation:
ASSUMING the given dimensions are the lengths of the legs
we have an equilateral triangle with base 4 and height
h = √(3² - (4/2)²) = √5
A = ½bh = ½(4)(√5) = 2√5 cm²
It is 20.
1st: set up a proportion. --> 95/100=19/x
2nd: cross multiply. --> 95 times x=95x. 100 times 19=1900.
3rd: divide 1900 by 95. --> 1900÷95=20
There you go! Your answer is 20
Answer is: 20 questions in total
We have that
(14/3)=(x/y²)-----------> 14*y²=3*x
then
(14/x)=(3/y²)
the answer is
3/y²
3n + 5 = 6
<u> - 5 - 5</u>
<u>3n</u> = <u>1</u>
3 3
n = ¹/₃
