The cost of a table is double the cost of a chair and the cost of a cupboard is five times the cost of a table. What is the ratio of the cost of the chair table and the cupboard? If the cost of a table is greater than that of a chair by rupees 2000 find the cost of a chair, table and the cupboard.
Answer:
Table 2: 1 Chair
Cupboard 5: 1 Table
Cupboard 10: 1 Chair
The table costs 4,000 rupees, the chair 2,000 rupees, and the cupboard costs 20,000 rupees.
Step-by-step explanation:
Since the cost of a table is double the cost of a chair and the cost of a cupboard is five times the cost of a table, to determine what is the ratio of the cost of the chair, the table and the cupboard the following calculations must be done:
Table 2: 1 Chair
Cupboard 5: 1 Table
5x2 = 10
Cupboard 10: 1 Chair
In turn, if the cost of a table is greater than that of a chair by 2000 rupees, to find the cost of a chair, table and the cupboard, the following calculations must be performed:
Table 2: 1 Chair
2000 x 2 = 4,000
Thus, the table costs 4,000 rupees and the chair 2,000 rupees.
4000 x 5 = 20,000
In turn, the cupboard costs 20,000 rupees.

Step-by-step explanation:
A central angle 0, in a circle of radius 4 ft intercepts an arc length of 50 ft.
Calculate the radian measure of 0.
Given:
The central angle = [tex]\theta[/tex]
Radius of the circle = 4 ft
Intercepted arc length = 50ft
To find:
The value of [tex]\theta [/tex] in radian measure.
Solution:
The formula for arc length is
[tex]s=r\theta[/tex]
where, r is radius and [tex]\theta [/tex] is the central angle in radians.
Putting s=50 and r=4, we get
[tex]50=4\theta[/tex]
Divide both sides by 4.
[tex]\dfrac{50}{4}=\theta[/tex]
[tex]12.5=\theta[/tex]
Therefore, the value of [tex]\theta [/tex] is 12.5 radians.

z scores are useful because they:a. allow us to convert raw scores to mean scores, compare scores from different samples, and transform populations into samples.b. transform linear scores into nonlinear scores, convert nonlinear scores back into linear scores, and allow us to obtain comparisons between nonlinear and linear scores.c. give us an understanding of where a score falls in relation to the mean of its underlying population, allow comparisons to be made between scores from different distributions, and permit the transformation of z scores into percentiles.d. reduce the probability of Type I and Type II errors, allow us to compare raw scores with standard scores, and permit the transformation of raw scores into percentiles.
Answer:
they give us a sense of where a score falls in relation to the mean of its population (in terms of standard deviation of its population), 2) they allow us to compare scores from different distributions, and 3) they can be transformed into percentiles.

A fruit seller brought 120 oranges for rs 500 and spent rs 60 for parking them into 10 boxes each containing a dozen oranges. If he sold a dozen of oranges for rs 58.8, find the profit percentage I know the answer it is 5% but I need the explanation for it in picture format it is also ok but in neat handwriting pls help
Answer:
First, we know that he spent rs500 plus rs60 in the whole process, then the total cost is:
C = rs500 + rs60 = rs560
Now he sells the oranges in packs of 12, then if he has 120 oranges, the total number of packs that he can sell is:
120/12 = 10
So he has 10 packs of 12 oranges.
And he sells each one for rs58.8
Then if he sells the 10 packs, the total revenue is:
R = 10*(rs58.8) = rs588
The profit is the difference between the revenue and the cost, here the profit is:
P = R - C = rs588 - rs560 = rs28
And the profit percentage is calculated as follows:
(P/C)*100%
Where P = profit and C = cost, then we have:
(rs28/rs560)*100% = 5%

The product of the rational expression 2/x(3/2 x-5) is 3-10/x.
What is expression?Expression is combination of numbers, fraction, symbols , coefficients, indeterminants or determinants. It shows a relationship between variables. It is mostly not found in equal to form.
How to find product?We have been given an expression 2/x(3/2 x-5) and we have to find the product of the expressions.
Product=2/x*3/2 x-2/x*5
To find the product of the expression, we have to multiply numerators with numerators and denominators with denominators and then perform the division part.
=6x/2x-10/x
=3-10/x
Hence the product of the rational expression 2/x(3/2 x-5) is 3-10/x.

Y=3x-2
Answer: -8, -5, -2, 1, 4
Step-by-step explanation:
Y=3x-2
- Plug in the number for x.
x = -2, y = 3x - 2= 3(-2) - 2 = - 6 - 2= - 8
x = -1, y = 3x - 2= 3(-1) - 2 = - 3 - 2= - 5
x = 0, y = 3x - 2= 3(0) - 2 = 0- 2= - 2
x = 1, y = 3x - 2= 3(1) - 2 = 3 - 2= 1
x = 2, y = 3x - 2= 3(2) - 2 = 6 - 2= 4

X miles = 30mins
cross multiply
450 × 30 = 60 × X
13500 = 60X
divide through by 60
225 = X
therefore, X = 225miles

Leah has just inherited $12,000. She wants to invest the money so that she can
increase the value of her inheritance. What are some of the ways she can do this?
1. Leah wants to invest the $12,000 in an account that pays 4.5% annual interest.
Part A
Write equations for the amount A(t) that will be in the account after t years, if the
interest is compounded continuously, daily, and monthly. Then, find the amount
after 10 years, rounded to the nearest cent, for each method of compounding.
Complete the table.
When interest compounded continuously so the amount after 10 years the amount will be $18819.75, when n = 365 and t = 10 years amount will be $18819.22, when n = 12 and t = 10 years amount will be $18803.91.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]A = P (1 + \frac{r}{n} )^{nt}[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
If the interest compounded continuously:
P = $12000, r = 4.5% = 0.045%
⇒ [tex]A (t) = 12000 (e)^{0.045t}[/tex]
When t = 10 years, plug this value in the above expression and calculating, we get;
A(10) = $18819.75
When interest compounded daily:
[tex]A(t) = 12000 (1 + \frac{0.045}{365} )^{365t}[/tex]
Plug t = 10 years:
We get;
A(10) = $18819.22
Similarly, If interest is compounded monthly:
n = 12 and t =10, we get:
A(10) = $18803.91
Thus, when interest compounded continuously so the amount after 10 years the amount will be $18819.75, when n = 365 and t = 10 years amount will be $18819.22, when n = 12 and t = 10 years amount will be $18803.91.

When y=48, x=4.2. If the value of y varies directly with x, what is the value of y when the value of x is 10.6?
Answer:
y = 121.14
Step-by-step explanation:
For this, we will need to start by cross multiplying.
(4.2 * y) = (48 * 10.6)
4.2y = 508.8
to isolate the varible, we need to divide both sides by 4.2
y = 121.14
