23) When a two digits number is divided by the sum of its digits, then the
quotient is 8 and the remainder is 2. If the digits are reversed and the
resulting number so formed is divided by the sum of the digits, the
quotient is 2 and the remainder is 8. Find the two digits number.
Answer: 82
Step-by-step explanation:
As we know remainder formula:-
Dividend = Quotient × Divisor + Remainder
Here, dividend = Two digits number & divisor = Sum of digits
m + 10n = 8 × (m + n) + 2
m + 10n = 8m + 8n + 2
m - 8m + 10n - 8n = 2
2n - 7m = 2
2n = 7m + 2
n = (7m + 2)/2 - - (Eq.1)
Digits interchanged, two digits number is divided by sum of digits, quotient is 2 & remainder is 8.
Now, when digits interchanged:-
Two digits number = 10m + n
Using same formula we get:-
10m + n = 2 × (m + n) + 8
10m + n = 2m + 2n + 8
10m - 2m + n - 2n = 8
8m - n = 8
8m = n + 8
n = 8m - 8 - - - (Eq.2)
Comparing both equations:-
(7m + 2)/2 = 8m - 8
7m + 2 = 2(8m - 8)
7m + 2 = 16m - 16
7m - 16m = -16 - 2
-9m = -18
m = -18/-9
m = 2
So, digit at unit's place = 2
Put this value in (Eq.2)
n = 8(2) - 8
n = 16 - 8
n = 8
So, digit at ten's place = 8
Now two digit number:-
Two digit number = 2 + 10(8)
Two digit number = 2 + 80
Two digit number = 82

The graph shows the function f(x) = 6(3)x. What is the value of the inverse function, f −1, at x = 2?
Answer:
There is an error in the equation.
f ( x ) = 63 X?? or whatt??
Answer:
-1
Step-by-step explanation:
y = f(x)
y = 6 * 3^x
Interchange x and y
x = 6 * 3^y
Divide by 6
x/6 = 3^y
Take the log of both sides
log(x/6) = log(3)^y
Bring the y down
log(x/6) = y log(3)
Divide by log(3)
log(x/6)/log(3) = y
Let x = 2
log(2/6) / log(3) = y
-(0.4771 )/ 0.4771 = y
y = - 1
Remark
The original graph is in green
The red graph is the inverse.
The point (2,-1) is marked so that you know it falls on the inverse.
A cone has a radius of 9 cm and a slant height of 15 cm. Find
the Volume.
Answer:
1017.88cm³
Step-by-step explanation:
The volume of cone will be;
⇒ V = 11,445.3 cm³
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
A cone has a radius of 9 cm and a slant height of 15 cm.
Now,
Since, Radius of cone (r) = 9 cm
Slant height (h) = 15 cm
We know that;
⇒ The volume of cone (V) = π r³ h / 3
Substitute all the values, we get;
⇒ V = 3.14 × 9³ × 15/3
⇒ V = 3.14 × 729 × 5
⇒ V = 11,445.3 cm³
Thus, The volume of cone = 11,445.3 cm³

Dylan bought 3 identical shirts online for a total cost of $71.83 including a flat rate (one time fee) of $7.99 for shipping. What equation can be used to determine the cost, s, of one shirt?
3s + 7.99 = 71.83
3 - 7.99s = 71.83
3 + 7.99s = 71.83
3s - 7.99 = 71.83

24 + 6 divide by 3 -2 (4 + 1)
Answer:
30
Step-by-step explanation:
Answer:
About -4.286
Step-by-step explanation:
First, let's set up the equation.
(24 + 6)/(3 - 2 [4 + 1])
Now, let us do the parenthesis first. (4 + 1). While we are at it, we can also do 24 + 6.
30/(3 - 2[5)]
Now, -2(5)
30/3 - 10
Let us do 3 - 10
30/-7
Lastly, 30/-7, which unfortunately, is a non-terminating decimal, which is about:
-4.286, rounded to the nearest thousandth.

Find the slope of the line passing through the points (-4,-5) and (3, -5).
Which expression gives the distance between the points (5, 1) and (9,-6)?
9514 1404 393
Answer:
C. √((5-9)² +(1+6)²)
Step-by-step explanation:
The distance formula can be written ...
d = √((x1 -x2)² +(y1 -y2)²)
Filling in the given point coordinates, this becomes ...
d = √((5 -9)² +(1 -(-6))²)
Simplifying the signs, this becomes ...
d = √((5 -9)² +(1 +6)²) . . . . . matches choice C

Is 8/10 larger than 79/100?
Answer:
Yes: this a fraction so the increase by a multiple of 10x does not change the value of 0.8 for option one being largest.
Step-by-step explanation:
Answer:
Yes! Let's take the denominator! Let's make 8/10 into the same denominator as 79/100, which is pretty easy! All we have to do is multiply the numerator by 10. So 8 x 10 = 80.
Our new fraction = 80/100 which is bigger than 79/100

Step-by-step explanation:
⬇ Hello! The answer would be down below! :) ⬇
x = 0 will be the answer.
Step-by-step explanation:
So, we start with [tex]\frac{3}{4} x = \frac{1}{5} x[/tex] .
For step 1 we should subtract [tex]\frac{1}{5} x[/tex] on both sides.
[tex]\frac{3}{4} x - \frac{1}{5} x = \frac{1}{5} x - \frac{1}{5} x[/tex]
= [tex]\frac{11}{20} x = 0[/tex]
For step 2 we will multiply both sides by [tex]\frac{20}{11}[/tex].
[tex](\frac{20}{11})[/tex] x [tex](\frac{11}{20} x ) = (\frac{20}{11})[/tex] x [tex]\ (0)[/tex]
= x = 0
Solve for x:
