The cost of a pair of shoes is Rs. 1000 . The GST charged was '5%' . Find the bill amount andalso find share of CGST, and SGST.
Answer:
Bill amount = Rs. 1050
CGST share = SGST share = Rs. 25
Step-by-step explanation:
We are told that the GST charged was 5% and cost of a pair of shoes is Rs. 1000. Thus;
Bill amount = 1000 + (5/100) × 1000
Bill amount = Rs. 1050
Now, CGST and SGST are both usually half of GST rate.
Thus;
CGST rate = SGST rate = 5%/2 = 2.5%
Thus;
CGST share = SGST share = 2.5% × 1000 = Rs. 25

A simple off bacteria is debating according to the half life model. If the simple begins with 800 bacteria, and after 18 minutes there is 240 bacteria, after how many minutes will there be 40 remaining
Answer:
After 43 minutes, the bacteria will be 40 remainings.
Step-by-step explanation:
Given that:
Initial population of bacteria [tex]A_o[/tex] = 800
After time (t) = 18 mins
A = 240
Using the model:
[tex]A = A_o e^{k*t}[/tex]
[tex]240=800 e^{k*18}[/tex]
[tex]\dfrac{240}{800}= e^{18k}[/tex]
[tex]0.3= e^{18k}[/tex]
By applying natural log on both sides, we get:
In(0,3) = 18k (In e)
- 1.20397 = 18 k * (1)
18 k = -1.20397
k = -1.20397/ 18
k = - 0.06688
k ≅ -0.07
After time (t), the bacteria population (A) = 40
Now;
[tex]40 = 800 e^{k*t}[/tex]
[tex]\dfrac{40 }{800}= e^{-0.07*t}[/tex]
[tex]0.05= e^{-0.07*t}[/tex]
In (0.05) = -0.07t * In (e)
- 2.9957 = - 0.07t
t = - 2.9957/ -0.07
t = 42.795
t ≅ 43 minutes
Thus, after 43 minutes, the bacteria will be 40 remainings.
Which absolute value number sentence is false? a. 171 +1-6 = 13 b. 1-151 - 1-8] = 7 c. 1-12 + 1-2 = 10 d. 1111 - 1-41 = 7
Answer:
C.
Step-by-step explanation:
This is because the absolute value of -12 is 12 and the absolute value of -2 is 2. So then the equation would look like this: 12 + 2 = 10, which is a false equation.

y = 5x + 3
Escriba su respuesta
Answer:
Slope (m) = 5
Y-intercept (b) = 3
Step-by-step explanation:
The equation of a line is y = mx + b, where (m) is the slope and(b) is the y-int.
Knowing this, we see that the slope is 5 and the y-int is 3.

Is y = 9x + 1/2 proportional?
Answer:
Yes it is
Step-by-step explanation:
The equation is proportional since as the value of x is increasing, y is also increasing
Equations can either be direct, inverse, or even joint. For instance, if y is directly proportional to x, this is expressed as:
y = kx
k is the variation constant
For a proportional equation, there an increase in a variable will lead to a decrease or increase in other variables
Given the expression y = 9x + 1/2,
when x = 1
y = 9(1) + 1/2
y = 9.5
when x = 2
y = 9(2) + 1/2
y = 18.5
We can see that the equation is proportional since as the value of x is increasing, y is also increasing

Liberty Middle School’s enrollment increased to 660 students. This is an increase of 10% over last year’s enrollment. What was last year’s enrollment?
Answer:
600
Step-by-step explanation:
Last years enrollment was 100% of the number.
This year, the enrollment went up by 10%, so now, it's 110% of last years number.
Let last year's enrollment be x.
110% of x is 660
1.1x = 660
x = 660/1.1
x = 600
Answer: 600

10.Let's solve for f.
gx=fx−4
Step 1: Flip the equation.
fx−4=gx
Step 2: Add 4 to both sides.
fx−4+4=gx+4
fx=gx+4
Step 3: Divide both sides by x.
fx/x=gx+4/x
The correct answer would be f= gx+4/x
11. Let's solve for f.
hx=12fx+2
Step 1: Flip the equation.
12fx+2=hx
Step 2: Add -2 to both sides.
12fx+2+−2=hx+−2
12fx=hx−2
Step 3: Divide both sides by 12x.
12fx/12x = hx-2/12x
The correct answer would be F= hx-2/12x
12. Let's solve for f.
kx=(−2f)(−x)
Step 1: Flip the equation.
2fx=kx
Step 2: Divide both sides by 2x
2fx/2x= kx/2x
The correct answer would be F= k/2
Side note: "/" is supposed to represent division and fractions
Answer:
10. f(x) was translated 4 units down
11. f(x) is stretched vertically by a factor of 12 and translated 2 units up
12. f(x) is stretched vertically by a factor of 2, reflected vertically along the x-axis, and reflected horizontally along the y-axis
Step-by-step explanation:
you have to explain what happened to f(x)
start by following the process SRT (stretch, reflection translation) for SR y then x transformations and for T x translation then y translation
Margo can purchase tile at a store for $0.69 per tile and rent a tile saw for $36. At another store she can borrow the tile saw for free if she buys tiles there for $1.29 per tile. How many tiles must she buy for the cost to be the same at both stores?
Answer:
30 tiles need to buy for same cost in both store.Step-by-step explanation:
Let x be the number of tiles to buy for same cost in both store.
18+0.69 · n = 1.29 · n,
1.29n -0.69n =18 or
0.6n =18
n =18/0.6=30
Therefore, 30 tiles need to buy for same cost in both store.[Ans]
