If the interest for 4 years on rupees 350 be Rs 112,find the rate percent. In what time will rupees 800 amount to rupees 1120 at the same rate of interest?
Using Simple Interest formula ,
The rate percent on amount of Rs.300 is 5.5 .
At same rate, R = 5.5 the principle 800 will be Rs1120 in next 7 years .
In first case we have given that ,
principle = Rs.350
time = 4 years
Amount = Rs 1120
simple interest = 1120-350 = Rs.770
let rate of interest be R% .
Using the formul of simple interest
S.I = P×R×t /100
=> 770 = 350×4×R/100
=> R = 5.5 %
In Second case , rate of interest is same as in first case. So,
Amount = Rs. 1120
Principle = Rs. 800
rate of interest (R)= 5.5
Again simple interest formula Used:
Simple Interest = (P × R × T)/100
Simple interest = 1120 - 800 = Rs. 320
Simple Interest = (P × R × T)/100
⇒ 320 = 800×5.5 ×T/100
=> T = 7.27 ~ 7
∴ In the given principle Rs 800 with same rate of interest will be 1120 in 7 next years .

the 30% increase is 1,500 comments made on the website.
A music video website received 5,000 comments on a new song they released.
The next day, the artist performed the song on television and an additional 1,500 comments were made on the website.
As we know,
The percentage increase = [(increase value)/(old value)]x100
Divide the increase by the beginning number and multiply by 100 to determine the percentage increase between two numbers:
Increase value = 1500
old value =5000
Percent of increase = (1500/5000)x100
Percent of increase = 0.3x100
Percent of increase = 30%
30% if the next day, the artist performed.
In mathematics, a percentage is various or a ratio expressed as a fragment of one hundred. it is often denoted the use of the percent sign, "%", despite the fact that the abbreviations "pct.", "pct" and sometimes "laptop" is also used. A percent is a dimensionless wide variety; it has no unit of measurement. The calculation of chances is done and taught in special approaches relying on the stipulations and necessities. in this manner, the same old formulas can be acquired with proportions, which saves them from having to remember them.

The rest of the cars use petrol.
Work out the number of cars that use petrol.
You must show all your working.
30 cars of the delivery company use petrol.
According to the question,
We have the following information:
A delivery company has a total of 160 cars and vans.
The number of cars: the number of vans = 3:7
1/8 of the cars use electricity.
25% of the cars use diesel and rest use petrol.
Let's take the number of cars to be 3x and the number of vans to be 7x.
3x+7x = 160
10x = 160
x = 160/10
x = 16
Number of cars = 3*16
Number of cars = 48
Now, cars that use electricity:
1*48/8
6 cars
Cars that use diesel:
25*48/100
12 cars
Cars that use petrol:
Total number of cars-(number of cars that use electricity and diesel)

Your ending inventories this week for pasta were 35, 41, 32, 19, and 47 boxes. You par value is 120 and a supplier comes each night. If the cost of a box of pasta is $2. 64, then what will you be charged for pasta this week?.
The cost of a box of pasta is $2. 64, then what will you be charged for pasta this week is $1,125.
Define cost.The average cost, or how much it generally costs to produce a unit, can be discovered using the cost function. The average cost function is defined as A(x)=C(x)x, where x > 0. The average cost per unit is calculated by dividing the total cost by the number of units produced.
Given,
Your ending inventories this week for pasta were 35, 41, 32, 19, and 47 boxes. You par value is 120 and a supplier comes each night.
Par level = [(120 - 35) + (120 - 41) + (120 - 32) + (120 - 19) + (120 - 47)]
Par level = [85 + 79 + 88 + 101 + 73]
Par level = 426 units.
Charges = par level × cost
Charges = 426 × 2.64
Charges = 1,124.64
Charges ≈ $1,125
The cost of a box of pasta is $2. 64, then what will you be charged for pasta this week is $1,125.

39.7 consumers believe that cash will be obsolete in the next 20 years. assume that 6 consumers are randomly selected. find the probability that fewer than of the selected consumers believe that cash will be obsolete in the next 20 years.
The probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is ;
Pr(C & fewer than 3) = 0.1985
What is probability?
Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
Here, we are required to find the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years.
Let Pr(C) be the number of consumers who believe that cash will be obsolete in the next 20 years.
Therefore, since 39.7% believe so,
Pr(C) = 39.7/100 = 0.397
If 6 consumers are selected randomly, the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years will be;
Probability of 2 out 6 to believe so or Probability of 1 out of 6 to believe so.
Pr(2/6) + Pr (1/6)
Therefore the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is;
Pr (fewer than 3) = (2/6) + (1/6)
Pr (fewer than 3) = 3/6
Therefore, the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is ;
Pr(C) × Pr (fewer than 3)
i.e 0.397 × (3/6) = 0.1985
Therefore, the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is ;

As per the given tax percent deduction from Marquis gross pay of $816 , the gross pay is reduced by $174.66.
As given in the question,
Gross pay taken by Marquis is equal to $816
Items withheld from Marquis gross pay are as follow:
1. Federal tax = $92
2. Social security tax = 6.2% of gross pay
6.2% of 816
= (6.2/100) × 816
= $50.592
3. Medicare tax = 1.45% of gross pay
= 1.45% of 816
= (1.45/100) × 816
= $11.832
4. State tax = 22% of federal tax
= 22% of 92
= ( 22 /100) × 92
= $20.24
Total reduced tax amount from Marquis gross pay
= $ ( 92 + 50.592 + 11.832 +20.24 )

above sea level. How far can she see to the horizon?
Round your answer to the nearest tenth.
kilometers
She can see the horizon till 2.604 meters when the person is standing at a height of 5.76 meters above sea level.
Given that,
If a person can see d kilometers into the distance from her eye level, which is h meters above sea level, then d=3.57 √h. Let's say the person is standing at a height of 5.76 meters above sea level.
We have to find she can see the horizon, but how far.
The SI unit of length is the meter. In addition to meters, length can also be expressed in other units like centimeters, inches, feet, and yards.
So,
d=h
3.57 √h= 5.76 meters
Divide both sides by 3.57
√h= 5.76 meter/ 3.57
√h=1.614
Squaring on both sides.
h=2.604
