Step-by-step explanation:
Rs 720
Cost of 1 m of cloth = 450/5= Rs 90
Cost of 8 m of cloth= 90*80= Rs 720
Answer:
The period of function is 5 and amplitude is 3.
Step-by-step explanation:
<em>The period of the function is the time interval after which it repeats itself.</em>
It means the time interval after which the same value of graph is attained.
In the above case looking at the peak point at time 5 seconds, the same value is obtained at time 10 seconds.
Thus the time interval is (10 - 5) 5 seconds.
<em>Amplitude is the maximum value attained by the graph in the complete interval.</em>
In the above case, the maximum value attained is 3.
Answer: p = 6
Step-by-step explanation:
HI !
px + 3y - ( p-3)=0
a₁ = p , b₁ = 3 , c₁ = - (p-3)
=====================
12x + py - p=0
a₂ = 12 , b₂ = p , c₂ = -p
since , the equations have infinite solutions ,
a₁/a₂ = b₁/b₂ = c₁/c₂
p/12 = 3/p = p-3/p
--------------------------------------
p/12 = 3/p
cross multiply ,
p² = 36
p = √36
p = 6
for the value of p = 6 , the equations will have infinitely many solutions
Answer:
- 
Step-by-step explanation:
Step 1: Add the numerator fractions.
2/5 + 3/10
Here we have to find LCD, the LCD of 5 and 10 is 10
(2*2) + 3 4 + 3
Therefore, 2/5 + 3/10 = --------------- = ------------------
10 10
= 7/10
Step 2: Now substitute 2/5 + 3/10 = 7/10 in the given fraction, we get
7/10
= ----------
-7/9
If we have fraction over fraction, we have to find the reciprocal of denominator fraction and multiply.
The reciprocal of -7/9 is -9/7
Step 3: Now multiply 13/10 and -9/7
= (7/10) x (-9/7)
= -9/10
=-9/10
The answer is -
