Let X and Y be the digits.
If a two-digit number is written XY, then its value is 10x+y.
When the digits of the number are interchanged, it's YX, and its value is 10y+x.
The sum of the digits is 12.
The number formed by interchaning the digits is 54 more than the original number.
The digits X and Y are 3 and 9, so the original number is 39.
Answer:Whales
Step-by-step explanation:
Simply just look at the line in the box which represent the median.
The value of x when y = 2 is x = 36
Step-by-step explanation:
The equation that we have in this problem is:
In order to find the value of x when y is equal to
y = 2
We need to re-arrange the equation making x the subject.
We proceed as follows:
1) We add +7 on both sides:
2) Now we multiply both sides by 4:
3) Now we can substitute y = 2 and find the value of x:

Answer:
Norton's
Step-by-step explanation:
Suppose that the down payment of Mazzeo's store = 1/3 on all installment purchases
Whereas Norton's depot required 30% down payment on installment purchases.
1/3 is fractional value of 33.33%.
therefore, Norton's Store's down payment rate is lower than that of Mazzeo's store.
Answer:
surface area we can also take it as total surface area
9 is the radius and 5cm is the height . as they asked total surface area we have to take the area of base so tht we can make it as
total surface area = csa of cylinder + area of base
we know that,
2pirh+pir²
pir(2h+r)
pir(2×5+9)
pir(10+9)
pir(19)
22/7×9×19
3762/7
=> 537.42 cm² is the answer.
