The maximum force in Newtons that can be safely applied to the tiles is; 735 N
How to calculate the force from pressure?
We are given the dimensions of the rectangular floor as;
Length = 1.6 m
Width = 2.3 m
Now, we are told that the tile is only able to sustain a maximum pressure
of 200 Newtons per square metre (N/m²). The formula for pressure here is; Pressure = Force/Area
Thus;
Force = Pressure * Area
Maximum force = 200 * (1.6 * 2.3)
Maximum force = 736 N
Since the Pressure was approximated to the nearest 5 N/m², then;
Maximum pressure will be approximated downwards to 735 N/m²

The maximum force in Newtons that can be safely applied to the tiles is 735 N.
Given that, the length of a rectangular floor tile=1.6 m and the width of a rectangular floor tile=2.3 m.
We need to calculate the maximum force, in Newtons, that can safely be applied to the tile.
What is the relation between force and pressure?Pressure is a measure of how much force is acting upon an area. Pressure can be calculated using the formula Pressure = Force/Area.
Now, the area of a rectangular floor tile=Length×Breadth=1.6×2.3 square meter
=3.68 square meter
Now, we are told that the tile is only able to sustain a maximum pressure of 200 Newtons per square metre (N/m²).
The formula for pressure here is Pressure = Force/Area
So, Force = Pressure×Area
= 200×3.68= 736 N
Since the Pressure was approximated to the nearest 5 N/m², then; maximum pressure will be approximated downwards to 735 N/m².
Hence, the maximum force in Newtons that can be safely applied to the tiles is 735 N.

A student measures the mass of a sample is 2.7 grams. What is the percent error, given that the correct mass is 2.58 grams? Round to the nearest hundredth of a percent.
Answer:
the percent error in the student's measurement is 4.65%.
Step-by-step explanation:
The percent error can be calculated using the formula:
| (measured value - actual value) / actual value | * 100%
In this case, the measured value is 2.7 grams and the actual value is 2.58 grams. Substituting these values into the formula, we get:
| (2.7 - 2.58) / 2.58 | * 100% = 4.65%
Rounding this to the nearest hundredth of a percent, we get a percent error of 4.65%.
Therefore, the percent error in the student's measurement is 4.65%.

Answer:
weight = gxg = 12kg to g = 0.12 and then using formula we get 0.12x0.12 = 1.44 is the weight
Step-by-step explanation:
Answer:
Therefore, the weight of the object is approximately 117.72 Newtons.
Step-by-step explanation:
The weight of an object is given by the formula:
weight = mass x acceleration due to gravity
The acceleration due to gravity on Earth is approximately 9.81 m/s².
So, the weight of an object with a mass of 12 kg is:
weight = 12 kg x 9.81 m/s² = 117.72 N
Therefore, the weight of the object is approximately 117.72 Newtons.
Swornima is an unmarried nurse in a
hospital. Her monthly basic salary is Rs
48,000. She has to pay 1% social
security tax on her income up to Rs
5,00,000 and 10% income tax on Rs
5,00,001 to Rs 7,00.000. She gets 1
months' salary as the Dashain
allowance. She deposits 10% of her
basic salary in Citizen Investment Trust
(CIT) and gets 10% rebate on her
income tax. Answer the following
questions. (i) What is her annual
income? How much tax is rebated to
her? (iii) How much annual income tax
should she pay?
To calculate Swornima's annual income and the amount of tax she should pay, let's break down the information provided:
Monthly basic salary: Rs 48,000
Social security tax rate: 1%
Income tax rate on income up to Rs 5,00,000: 0% (no tax)
Income tax rate on income from Rs 5,00,001 to Rs 7,00,000: 10%
Dashain allowance: 1 month's salary
Deposit in Citizen Investment Trust (CIT): 10%
Rebate on income tax: 10%
(i) Annual Income:
Swornima's monthly basic salary is Rs 48,000, so her annual basic salary would be:
Annual Basic Salary = Monthly Basic Salary x 12
= Rs 48,000 x 12
= Rs 5,76,000
Additionally, she receives 1 month's salary as the Dashain allowance, which we can add to her annual income:
Annual Income = Annual Basic Salary + Dashain Allowance
= Rs 5,76,000 + Rs 48,000
= Rs 6,24,000
Swornima's annual income is Rs 6,24,000.
(ii) Tax Rebate:
Swornima receives a 10% rebate on her income tax. To calculate the rebate, we need to determine her income tax first.
(iii) Annual Income Tax:
First, let's calculate the income tax for the range of income from Rs 5,00,001 to Rs 7,00,000. The tax rate for this range is 10%.
Taxable Income in this range = Rs 6,24,000 - Rs 5,00,000
= Rs 1,24,000
Income Tax in this range = Taxable Income x Tax Rate
= Rs 1,24,000 x 0.1
= Rs 12,400
Now, let's calculate the total annual income tax:
Total Annual Income Tax = Income Tax in the range Rs 5,00,001 to Rs 7,00,000
= Rs 12,400
Next, we calculate the rebate on income tax:
Tax Rebate = Total Annual Income Tax x Rebate Rate
= Rs 12,400 x 0.1
= Rs 1,240
Swornima's annual income tax is Rs 12,400, and she receives a tax rebate of Rs 1,240.
To summarize:
(i) Swornima's annual income is Rs 6,24,000.
(ii) Swornima's tax rebate is Rs 1,240.
(iii) Swornima should pay an annual income tax of R
Reuben made a shirt using 7/8yards of red fabric and 1/4yards of yellow fabric. How many more yards of red fabric did Reuben use?
Answer and Step-by-step explanation:
To find out how many more yards of red fabric Reuben used, we need to subtract the amount of yellow fabric from the amount of red fabric. Since the two fractions have different denominators, we need to find a common denominator before subtracting them. The least common multiple of 8 and 4 is 8, so we can rewrite both fractions with a denominator of 8:
7/8 - 1/4 = 7/8 - (1/4) * (2/2) = 7/8 - 2/8 = (7 - 2)/8 = 5/8
So, Reuben used 5/8 yards more red fabric than yellow fabric.
For the concentric circles shown, the radius of the inner circle is 3 centimeters and the distance from the
cdge of the inner circle to the edge of the outer circle is 7 centimeters. What is the exact arca, in squarc
centimeters, of the shaded outer region?
Answer:
d
Step-by-step explanation:
Area of the inner circle = 3^2 π = 9 π
total area = 10^2 π = 100π
area of the shaded region
100π - 9 π = 91 π
The area of the shaded region is 91π square cm if the radius of the inner circle is 3 centimeters and the distance from the edge of the inner circle to the edge of the outer circle is 7 centimeters option (d) is correct.
What is a circle?It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).
We have:
The radius of the inner circle r = 3cm
The distance from the edge of the inner circle to the edge of the outer circle = 7 cm
So the radius of the outer circle = 7+3 = 10 cm
Area of the inner circle = π(3)² = 9π square cm
Area of the outer circle = π(10)² = 100π square cm
Area of the shaded region = 100π -9π = 91π square cm
Thus, the area of the shaded region is 91π square cm if the radius of the inner circle is 3 centimeters and the distance from the edge of the inner circle to the edge of the outer circle is 7 centimeters option (d) is correct.

Answer:
x = 16°
Step-by-step explanation:
What we know:
∠JML = 47°
∠JKL = (7x + 21)°
∠JML is an inscribed angle
∠JKL is an inscribed angle
Inscribed angles are half of the value of their intercepted arc
So if m∠JML = 47° then mArc JL is double that or 94°
And ∠JKL is intercepted by Arc JML which is the rest of the circle not intercepted by ∠JML so
mArc JL + Arc JML = 360°
94 + Arc JML = 360
Subtract 94 from both sides to isolate Arc JML
Arc JML = 266°
So if Arc JML = 266° then it's intercepted inscribed angle is half of that.
Arc JML ÷ 2 = ∠JKL
266 ÷ 2 = ∠JKL
133 °= ∠JKL
Now we can use this value and set it equal to the expression to find the value of x
(7x + 21) = 133
Subtract 21 from both sides to isolate the x
7x = 112
Divide both sides by 7
x = 16

The percentage of the DVD the store sells that are Brand A = 50%
Percentage of the DVD player that are Brand B = 30%
Percentage of the DVD players that are Brand C = 20%
Percentage of the Brand A DVD players that need repair in the first year = 25%
Percentage of the Brand B DVD, players that need repair during the first year = 10%
Percentage of Brand C DVD players that need repair in the first year = 5%
Therefore, we get;
Brand A need service = 25% × 50% = 12.5%
Brand A Good Condition = (100 - 25)% × 50% = 37.5%
Brand B need service = 10% × 30% = 3%
Brand B Good Condition = (100 - 10)% × 30% = 27%

cm 84. A father's age was three times and two times of his son at 2040 and 2050 respectively. What will be the birth year of son? a. 2030 b. 2035 c. 2031 d. 2032 100
Answer:
(a)2030
Step-by-step explanation:
I'm assuming the 100 at the end of the question is a typo.
In 2040, the son's age can be written as \(\frac{x}{3}\), where x equals the age of his father. In 2050, the son's age can be written as \(\frac{x-10}{2}\) (as ten years is added between 2040 and 2050). When equated to each other--> \(\frac{x-10}{2}\) = \(\frac{x}{3}\), we can first simplify by multiplying both sides to reach the least common denomination 6, giving us 3(x-10)=2x --->3x-30=2x--->x=30 is the dad's age. The son's age in 2040, 30/3, is equal to 10 years, meaning he was born in the year 2030 (a).
