Answer:
A≈94.25in²
Step-by-step explanation:
Answer:
Solutions are (6,3) and (-2,3).
Step-by-step explanation:
From the first equation given we can write:
substituting for 
in the second equation given we get
∴ y=3
Putting y=3 in the first equation we get
x-2 = ±4
Hence x=6 or x=-2.
Answer:
i. 30.5m
ii. 930.25m²
iii. Rs. 37,218
Step-by-step explanation:
Perimeter of a square = 4 * Length
i. Length = Perimeter/4
= 122/4
= 30.5 m
ii. Area = Length * Height
= 30.5 * 30.5
= 930.25 m²
iii. Cost of growing grasses at Rs. 40 per m²
= 930.25 * 40
= Rs. 37,218
Answer:
167.10
Step-by-step explanation:
Here, we write out the general form for an exponential equation;
y = I (1 + r)^n
where y is the current value which we want to calculate
I is the initial value which is 160
r is the growth rate = 0.65% = 0.65/100 = 0.0065
402 minutes to hours will be 402/60 = 6.7 hours which is n
Substituting these values, we have
y = 160( 1 + 0.0065)^6.7
y = 160(1.0065)^6.7
y = 167.10
