Answer:
Nope they are not parallel.
Step-by-step explanation:
first find the slope of each equation.
-4x+4y= -1
4y= 4x -1
y= (4x-1)/4
y=x - 1/4
the other equation
4x +4y = -1
4y= -4x -1
y= (-4x-1)/4
y= -x -1/4
the slope is the number in front of the x so for the first equation, it is 1 and the second equation it is -1. Since they are not the same, they are not parallel but instead is perpendicular. TBH, just stop here as this is more than enough.
Eq. 1 .10x + .25y = 9.45
Eq. 2 x + y = 60 rewrite as x = 60 - y and substitute into equation 1.
.10(60 - y) + .25y = 9.45
6 - .1y + .25y = 9.45
6 + .15y = 9.45
.15y = 3.45
y = 23
60 - 23 = 37
23 quarters
37 dimes
23* .25 = 5.75
37 * .1 = 3.70
5.75 + 3.70 =9.45
Answer:
803.84 Cm Squared
Step-by-step explanation:
A= π r2
A = 3.14 times 16 squared
A = 803.84
Answer:
so the answer is RS 20200
Step-by-step explanation:
simple formula for calculation ( as for compound interest you have to invest initially)
starting total investment Pₓ = Rs 150000
Interest rate r= 6 % = 0.06
compounds in years total K = (12 months)
for how many year you want to invest Pₙ = 5
formula
Pₙ = Px (1 + r/k) ⁿ ˣ ¹²
P₅ = 150000 (1 + .06/12) ¹² ˣ⁵
= 150000 (1.005) ⁶⁰
= 150000 x 1.348
= Rs 202200
