The operating ratio of the local ice cream shop is 38 percent
The cost of goods sold is $2,500
The net sales is $18,200
The operating expenses is $4,350
The operating ratio can be calculated as follows
= cost of goods sold+ operating expenses/total revenue
= 2500+4,350/18,200
= 6,850/18,200
= 0.376×100
= 37.6
= 38%
Hence the operating ratio is 38%

Mrs kanja ,miss kanene and Mrs nyaga have to mark a form three contest for 160students .They take 5mins ,4mins and 12mins respectively to mark a script .If they all start to mark at 9.00am non-stop ,what is the shortest time they ca n take to complete the marking?
Answer:
300 minutes
2:00 p.m
Step-by-step explanation:
Given the following:
Time taken to mark a script :
Mrs Kanja = 5mins
Miss Kanene = 4mins
Mrs Nyaga = 12 mins
Number of scripts = 160
Start time = 9:00 a.m
Rate at which each of them mark:
Mrs Kanja = t / 5
Miss Kanene = t/4
Mrs Nyaga = t/12
Combined rate :
t/5 + t/4 + t/12 = 160
(12t + 15t + 5t) / 60 = 160
32t / 60 = 160
32t = 160 * 60
32t = 9600
t = 9600 / 32
t = 300 minutes
300 minutes = 300/60 = 5hrs
9:00 a.m + 5 hours = 2:00 p.m

PLS HELP IMMEDIATLYRewrite the equation by completing the square. 4 x^{2} +8 x +3 = 0 in (x+_)^2=_
Answer:
(x + 1)^2 = 1/4
Step-by-step explanation:
Here, we want to rewrite the equation by completing the square.
The equation to rewrite is;
4x^2 + 8x + 3 = 0
4x^2 + 8x = -3
divide through by the coefficient of x^2 which is 4
That will give ;
x^2 + 2x = -3/4
Now divide the coefficient of x by 2, square it and add to both sides of the equation.
We have;
x^2 + 2x + 1^2 = -3/4 + 1^2
x^2 + 2x + 1 = -3/4 + 1
x^2 + 2x + 1 = 1/4
= (x + 1)^2 = 1/4

Answer: 25.6
First, notice that there is 1 adult and 2 children.
A normal adult ticket costs 24. But it's 1/3 off, so 24 * 1/3 = 8 off. That means with the Railcard, it only costs 24 - 8 = 16.
Next, one child ticket costs 12. But it's 60% = 3/5 off, so 12 * 3/5 = 7.2 off. That means with the Railcard, it only costs 12 - 7.2 = 4.8.
Remember there are 2 children, so we multiply by 2 to get 4.8 * 2 = 9.6 for the children.
Final answer: 1 adult + 2 children = 16 + 9.6 = 25.6.
Hope that helped,

Answer:
£25.60
Step-by-step explanation:
Adult tickets cost £24 and ⅓ is off the adult tickets according to the Family Railcard. That is:
24 × ⅓ = £8 is removed from the adult tickets. Therefore:
£24 - £8 = £16
Child tickets cost £12 and 60% is off the child tickets according to the Family Railcard. That is:
12 × 60/100 = £7.20 is removed from the child tickets. Therefore:
£12 - £7.20 = £4.80
To find the total cost of Mr. Brown spent:
1 child = £4.80
2 children = ?
4.80 × 2 = £9.60
1 adult = £16
£16 + £9.60
= £25.60
Mr. Brown spent £25.60 in total.
if AD is the altitude to BC what is the slope of AD
Answer:
The answer is most likely 1/3
The correct option D. 3. The slope of AD, where A is (-2, 4), B is (-6, 2), and C is (3, -1), is 1/3 using the slope formula.
Given points :
[tex]A(-2, 4)\\B(-6, 2)\\C(3, -1)[/tex]
To find the slope of AD, to determine the slope of the line passing through points A and D.
Calculate the slope of the line passing through points A and D using the formula:
slope [tex]= (y_2 - y_1) / (x_2 - x_1).[/tex]
First, let's find the slope of BC using the coordinates of points B and C:
Slope of BC [tex]= (y_2- y_1 / (x_2- x_1)\\[/tex]
Plugging the coordinates of points B and C gives:
[tex]= (-1 - 2) / (3 - (-6))[/tex]
On adding gives:
[tex]= (-3) / (9)[/tex]
On dividing both numerator and denominator by 3
[tex]= -1/3[/tex]
Since A is the altitude to BC, it is perpendicular to BC.
The slope of a line perpendicular to another line is the negative reciprocal of the slope of that line.
Therefore, the slope of AD will be the negative reciprocal of -1/3.
Negative reciprocal of -1/3 = -1 / (-1/3) = 3
Hence, the slope of AD is 3. The option is D. 3

Describe the effort of translating tringle abc to tringle a'b'c
Answer:
Each x-coordinate increased by 6 and each y-coordinate decreased by 3.
Step-by-step explanation:
Let us use the coordinates of a and a' as an example
a = (-3, 5) a' = (3, 2)
So -3 is for the x-axis in coordinate a and 3 is for the x axis in coordinate a'
Then -3 + 6 = 3 ( This is the x coordinate for a' )
So 5 is for the y -axis in coordinate a and 2 is for the y axis in coordinate a'
Then 5 - 3 = 2 ( This is the y coordinate for a' )

on a map the distance between rip and Janeiro Brazil and San Jose Costa Rica is 4 inches.the scale on the map shows that 1 inch=200 miles ,or if you write it as a ratio.. how would set up a proportion if you want to figure out how many miles it is form Rio de Janeiro to San jose.?
Answer:
The way a proportion is set is as follows;
[tex]\dfrac{1 \ inch}{200 \ miles } = \dfrac{4 \ inches}{ Distance \ from \ Rio \ de \ Janeiro \ to \ San \ Jose}[/tex]
The Distance from Rio de Janeiro and San Jose Costa Rica is then found as 800 miles

The map scale = 1 inch to 200 miles
To figure out how many miles it is or the actual distance from Rio de Janeiro and San Jose Costa Rica, we have;
[tex]\dfrac{1 \ inch}{200 \ miles } = \dfrac{4 \ inches}{ Distance \ from \ Rio \ de \ Janeiro \ to \ San \ Jose}[/tex]
Therefore, we have;
(4 inches × 200 miles)/(1 inche) = Distance from Rio de Janeiro and San Jose Costa Rica
Which gives;
Distance from Rio de Janeiro and San Jose Costa Rica = 800 miles.

Insert 2 rational numbers between -1/3 and -1/2
Answer:
-11/24 and -4/9
Step-by-step explanation:
A rational number is a fraction in the form a/b where both a and b are integers and b is not equal to zero.
Given the numbers -1/3 and -1/2, to place two numbers between them, we have to first find the width between the two numbers.
Width = -1/3 - (-1/2) = -1/3 + 1/2 = 1/2 - 1/3 = 1/6
Since two numbers are to be placed between -1/3 and -1/2, we have to divide the width into 3 which results to 1/6 ÷ 3 = 1/18
The first number placed is -1/3 - 1/18 = -11/24
The second number is -11/24 - 1/18 = -4/9

A quadrilateral can be inscribed in a circle only if the sum of its opposite angles is equal to 180°, so:
7x - 15 + 3x + 15 = 180° and 2(17y - 10) + 13y + 12 = 180°
10x = 180° 34y - 20 + 13y + 12 = 180°
x = 18° 47y = 188°
y = 4°
m∠M: 2(17•4 - 10) = 2•58° = 116
m∠N: 7•18 - 15 =126 - 15 = 111
m∠O: 13•4 + 12 = 52 + 12 = 64

bca=100b+10c+a
cab=100c+10a+b
abc + bca + cab=(100a+10b+c) + (100b+10c+a) + (100c+10a+b)
=100a + 10b + c + 100b + 10c + a + 100c + 10a + b
Collect like terms
=100a + a + 10a + 10b + 100b + b + c + 10c + 100c
=111a + 111b + 111 c
Factorise
=111(a+b+c)
abc + bca + cab = 111(a+b+c)
Factors of 111(a+b+c)= 1, 3, 37, 111, and (a+b+c)
abc + bca + cab is divisible by a+b+c because it is a factor of 111(a+b+c)
abc + bca + cab is divisible by 3 because 3 is a factor of 111(a+b+c)
abc + bca + cab is divisible by 37 because 37 is a factor of 111(a+b+c)
abc + bca + cab is not divisible by 9 because 9 is not a factor of 111(a+b+c)

What is the period of y=sin x
Answer:
The period of y = sin(x) is 2π
The period of y = sin x would be equal to 2π.
The period of the function y = sin x refers to the length of one complete cycle of the graph of the sine function.
In this case, the period is calculated by the coefficient of x, which is 1.
For the function y = sin x, the period is 2π which means that the graph of y = sin x repeats itself every 2π units along the x-axis.
If the graph of y = sin x. Starting from the point (0,0), as x increases by 2π, then the y-values will repeat the same pattern. This repetition continues indefinitely as x increases or decreases.
Therefore, we can conclude that the period of y = sin x is 2π.
