Answer:
Here we can take advantage of exactly the property suggested by Xisca... that is, sqrt(44)=2sqrt(11), which reduces the calculation to more accuracy with a lesser knowledge of the squares of numbers.
As a first approximation, we know that 33*33=1089, or 3.3*3.3=10.89, which is already very close to 11.
Thus a first approximation to sqrt(44)=2sqrt(11)=2*3.3=6.6 (approximately).
To refine the calculation of sqrt(11), we use Newton's approximation, namely
a better approximation is given by 3.3 + (11 - 3.3^2) / (2*3.3) = 3.3+0.11/6.6 = 3.3+1/60
which gives
sqrt(44) = 2(3.3+1/60) = 6.6+1/30 = 6.6333,
actually accurate almost to the nearest 1/10000.
All of the above can be done mentally
For those who need help with rounding to the nearest hundredth (0.01), we drop digits AFTER the 2nd decimal, namely *.**33. If the first digit dropped is 5 or more, add one to the last digit retained, otherwise, retain only the two digits after the decimal. In this case, the first digit dropped is 3, so it will simply be dropped. The final answer is then 6.63, to the nearest hundredth.

Which is the x-intercept for 4x − 2y = 16?
Answer:
4
Step-by-step explanation:
Remember, the x-intercept of a function is where the graph intersects the x-axis. A function only intersects the x-axis when y = 0.
To find the x-intercept of the function 4x - 2y = 16, lets set y = 0 and solve for x:
4x - 2(0) = 16
4x = 16
x = 4
So the x-intercept of the function would be 4.

find the simple interest on $1500 for 5 years at 3.5%
Answer:
$1781.53
Step-by-step explanation:
Simple Interest Rate Formula: A = P(1 + r)ⁿ
Step 1: Define variables
Principle amount P = 1500
Rate r = 0.035
Years n = 5
Step 2: Substitute and Evaluate for A
A = 1500(1 + 0.035)⁵
A = 1500(1.035)⁵
A = 1500(1.18769)
A = 1781.53

Write any two negative integers greater than – 8
Answer:
-6 and -7
Step-by-step explanation:
greater has the meaning of more positive in math, which is equivalent to being less negative, so two negative integers greater than -8 are two that have a value lower than 8, in this case from 1 to 7 (0 is neither positive nor negative)
so a possible answer is -7 and -6

A woman buys an item marked Rs. 3,060 after allowing a discount of 15% with 10% VAT. How much does she pay for it?
After applying a 15% discount and adding a 10% value-added tax (VAT), a woman pays a different amount than the original price of Rs. 3,060 for the item.
The original price of the item is Rs. 3,060. To calculate the final amount paid by the woman, we first apply a 15% discount to the original price. A 15% discount on Rs. 3,060 is calculated as (15/100) x 3,060 = Rs. 459. After deducting the discount, the revised price becomes Rs. 3,060 - Rs. 459 = Rs. 2,601.
Next, a 10% value-added tax (VAT) is applied to the revised price. The VAT amount is calculated as (10/100) x 2,601 = Rs. 260.1. Adding the VAT amount to the revised price, the final amount paid by the woman is Rs. 2,601 + Rs. 260.1 = Rs. 2,861.1.
Therefore, the woman pays Rs. 2,861.1 for the item after allowing a 15% discount and adding a 10% VAT.

The cost of parking is not proportional to the number of hours parked.
We need to check whether the cost of parking is proportional to the number of hours parked.
The ordered pairs from the table is (1, 4), (5, 10) and (12, 15).
What is the direct variation?A direct variation is a proportionality relationship in which two quantities follow a direct relationship.
Taking hours as abscissa and cost as ordinate. We can get the coordinate of three points: (1, 4), (5, 10) and (12, 15) mark it on the graph.
The cost of parking is not proportional to the number of hours parked.
That is, 10-4/5-1≠15-10/12-5

y = five-halves x, where y is the cost in cents for a book that is x days overdue
y = 5 x, where x is the cost in cents for a book that is y days overdue
y = 5 x, where y is the cost in cents for a book that is x days overdue
Mark this and return
Answer:
The answer would be B!
Step-by-step explanation:
In the chart if you divide the number of days over due to the cost of the fine, you get 5/2 every time. therefore, if y is the cost in cents and x is the days overdue, you would multiply x5/2 or y=5/2x, so your answer is B (y=5/2x).

Step-by-step explanation:
Vehicles generally decrease in value around 14% per year. If you buy a vehicle priced at $39,500 , this can be modeled by the equation A=39500(0.86)t . Estimate the value of the vehicle after 4 years. Round to the nearest cent and do not round until the final calculation.
Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20..
To estimate the value of the vehicle after 4 years, we can use the given equation A = 39500(0.86)^t, where A represents the value of the vehicle and t represents the number of years.
Substituting t = 4 into the equation:
A = 39500(0.86)^4
A ≈ 39500(0.5996)
A ≈ 23726.20
Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20.
This estimation is based on the assumption that the vehicle's value decreases by 14% each year. The equation A = 39500(0.86)^t models the exponential decay of the vehicle's value over time. By raising the decay factor of 0.86 to the power of 4, we account for the 4-year period. The final result suggests that the value of the vehicle would be around $23,726.20 after 4 years of ownership.

Answer:
common factors: 1, 2, 4common multiples: any multiple of 168, including 168, 336, 504, 672Step-by-step explanation:
Common factors of 12 and 56 will be factors of the greatest common factor (GCF) of those numbers. That can be found several ways. One is to list the prime factors of each number, then choose the ones that are common.
12 = 2·2·3
56 = 2·2·2·7
The common factors are 2·2. Of course 1 is always a factor. So, "all common factors" are 1, 2, 4.
__
The least common multiple (LCM) can be figured using the same lists of factors. It must include all of the factors (only as many times as necessary), so will be ...
2·2·2·3·7 = 168
It can also be figured as the product of the two numbers, divided by their GCF:
12·56/4 = 168
Any "common multiple" will be a multiple of this LCM. Some common multiples of 12 and 56 are ...
1·168 = 168; 2·168 = 336; 3·168 = 504
