Answer:
She purchased the item at a price of Rs 1,406.
Step-by-step explanation:
5% of discount:
This means that she paid 100% - 5% = 95% = 0.95 of the original price of x, that is, 0.95x, and 0.05x was the discount.
Original price:
She got the discount amount of Rs 74.
74 is 5% of the original price, that is:
What price she purchased:
74 subtracted from the original price, that is, x - 74. So 1480 - 74 = 1406.
She purchased the item at a price of Rs 1,406.
Answer:
10
Step-by-step explanation:
Means back the numbers into multiples of several small numbers
Like:; 1. We take LCM of 40
Just break into multiples of small number
40= 2×2×2×5
2. We take LCM of 50
50= 5×5×2
So LCM for 100 is 2×2×5×5
after that see the pairs in the LCM like 2×2 or 3×3 or 4×4(same numbers)
Then write the the single number in place of two multipled numbers
Like:; 2×2 is written as 2 // 3×3 is written as 3
So we can write 100 into 2×2×5×5 and then after selecting pairs (2×2)×(5×5)
write pairs in single number 2×5
And so we get 2×5=10
So we find root of 100 that is 10
Answer:
four tens
Step-by-step explanation:
four tens is greater because:
four tens = 40
thirty six and nine thousandths = 36.009
36.009 < 40
Answer:
C.
Step-by-step explanation:
We proceed to solve for by the Pythagorean Theorem:
(1)
There are two different solutions:
,
A solution of is considered realistic when the length of every side of the triangle is a not negative number.
The only realistic set of solutions is for , and the radius of the circle is represented by the line segment :
And the area of the circle () is calculated from the following formula:
The correct answer is C.
Answer:
Step-by-step explanation:
Equation of a circle:
The equation of a circle with center is given by:
In which r is the radius.
Center (-14, -3)
This means that
So
Passes through the point (-5,3),
This means that when . We use this to find the radius squared. So
So, the equation of the circle is:
