the picture in the attached figure
we know that
In a Rhombus the diagonals are perpendicular bisectors of each other
so
LP=PN
and
LP=LN /2
LP=28 /2-------->LP=14 cm
the answer is
Lp=14 cm
Answer:
x= - 3
Step-by-step explanation:
A+B+C=180
A=55
B=54
C=x+74
55+54+(x+74)=180
109+(x+74)=180
x+74=71
x=-3
<u>Answer-</u>
2, 4, and 8 people will need 1, 2, 4 pounds of turkey respectively.
<u>Solution-</u>
Given in the question, number of pounds of turkey varies directly with the number of people, i.e as the number of people increases or decreases, the pound of turkey also increases or decreases.
Taking,
x = number of people,
y = pounds of turkey.
This condition can be represented as,
As given in the question, when x = 6 y = 3
Now, putting the values of k in the equation, the equation becomes
Now, we can get the values of y or number of pounds of turkey needed by putting the given x or number of people.
All the calculations are shown in the attached table.
Supplementary angles add up to 180 degrees. to find one just subtract.
180- 42= 138
Let selling price = SP and cost price = CP
He makes 20 % on selling price means = >
(sp-cp) / sp = 20 % = 20/100 = 0.2
(sp - cp) / sp = 0.2
1 - cp/sp = 0.2
1 - 0.2 = cp/sp
0.8 = cp/sp
Reversing 1 / 0.8 = sp/cp = 1.25
We need to find profit on cost price means =
=(sp-cp)/ cp
= sp/cp - 1 = 1.25 - 1 = 0.25
Means 25 % profit on cost price : Answer
Hope that will help :)
