Answer: 7
Step-by-step explanation: if it a square then both side have to be same length so just divide 14 by 2 to get 7
hope this helps mark me brainliest please
Let side be "a" cm. So another side is (30-2a)/2=15-a
S=ab=a(15-a)=15a-a^2 - parabola
maximum when a = -15/-2=7.5 cm
When a=7.5 all sides are 7.5 cm
So it's a square. S=a*a=7.5*7.5=56.25 cm^2 - max
There is no global minimun for S.(look at the graphic)
Answer:
B. Dependent, 1/70
Step-by-step explanation:
The probability that the first pencil is yellow is 10/50.
There are now 49 pencils, so the probability that the second pencil is blue is 7/49.
There are now 48 pencils, so the probability that the third pencil is red is 24/48.
The total probability is (10/50) (7/49) (24/48) = 1/70.
Since the pencils aren't replaced after selection, each event changes the probability of the next, so the events are dependent.
A square has four right angles and four equal sides.<span> It belongs to the set of polygons known as quadrilaterals, which are shapes with four sides.</span>
Answer: 0.10(n)=25+0.05(n-200)
Explanation:
The number of business cards are n
Plan A: No initial fee and $0.10 for each business card
Plan B: $25 for the first 200 business cards
and surplus of $0.05 for each additional card
As n is total business cards
so from plan A equation is
0.10(n)
from plan B
25 + 0.05(n-200) if n > 200
Now as a whole the equation for no of business cards would be
0.10(n)=25+0.05(n-200)
