The rounded number is given by A = 2
What is rounding up numbers?There are basically two rules while rounding up numbers
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
Non-zero digits are always significant
Zeros between non-zero digits are always significant
Leading zeros are never significant
Trailing zeros are only significant if the number contains a decimal point
Given data ,
Let the rounded number be represented as A
Let the number be represented as n
Now , the value of n = 1.75
And , when you round to the nearest ones place. The 1 in the ones place rounds up to 2 because the digit to the right in the tenths place is 7.
When the digit to the right is 5 or greater we round away from 0.
So , the rounded number is A = 2
Hence , the rounded number is A = 2

Answer:
The correct options are 1 and 3.
Step-by-step explanation:
It is given that x represents the number of small boxes and y represents the number of large boxes.
The post office has 10 small boxes and 9 large boxes in stock.
He needs at least 4 small boxes.
[tex]4\leq x\leq 10[/tex]
He will buy no more than 15 boxes.
[tex]6+9=15\leq 15[/tex]
[tex]8+6=14\leq 15[/tex]
Therefore options 1 and 3 are correct.
[tex]x+y\leq 15[/tex]

.04 is 1/10 of what number
Answer:
0.4
Step-by-step explanation:
Let x be 1/10 of 0.04.
1/10 of x would be [tex]\frac{1}{10}x[/tex].
We can represent our given information in an equation as:
[tex]\frac{1}{10}x=0.04[/tex]
Let us solve for x.
[tex]10*\frac{1}{10}x=10*0.04[/tex]
[tex]x=0.4[/tex]
Therefore, 0.04 is 1/10 of 0.4.

Four friends measure the length of a 6-millimeter-long grain of rice. They record their measurements as shown. Andrey: 7 mm, 5 mm, 6 mm, 8 mm Mariya: 7.41 mm, 8.54 mm, 5.12 mm, 6.23 mm Yuto: 6.1 mm, 5.9 mm, 6.3 mm, 7.2 mm Misaki: 5.843 mm, 6.981 mm, 5.334 mm, 7.632 mm Whose measurements are the most accurate? Andrey’s Mariya’s Yuto’s Misaki’s
Yuto's measurements are the most accurate since they have the smallest mean absolute deviation from the correct length of 6 mm. Hence Option 3 is Correct
To determine whose measurements are the most accurate, we need to compare each friend’s measurements against the correct value of the grain of rice, which is 6 mm. The accuracy of measurements corresponds to how close they are to this true value.
Let's look at each friend's measurements:
Andrey: 7 mm, 5 mm, 6 mm, 8 mmMariya: 7.41 mm, 8.54 mm, 5.12 mm, 6.23 mmYuto: 6.1 mm, 5.9 mm, 6.3 mm, 7.2 mmMisaki: 5.843 mm, 6.981 mm, 5.334 mm, 7.632 mmTo evaluate accuracy, we calculate the deviation of each measurement from 6 mm, then find the mean absolute deviation for each friend:
Andrey: Mean = ( |7-6| + |5-6| + |6-6| + |8-6| ) / 4 = 1.5 mmMariya: Mean = ( |7.41-6| + |8.54-6| + |5.12-6| + |6.23-6| ) / 4 = 1.52 mmYuto: Mean = ( |6.1-6| + |5.9-6| + |6.3-6| + |7.2-6| ) / 4 = 0.625 mmMisaki: Mean = ( |5.843-6| + |6.981-6| + |5.334-6| + |7.632-6| ) / 4 = 0.906 mmHere, Yuto's measurements are the most accurate since they have the smallest mean absolute deviation from the correct length of 6 mm.
Yuto's measurements are the most accurate.
Andrey: 7 mm, 5 mm, 6 mm, 8 mm

Write the equation of the line as shown below,
y = m x + 12
Here, m is the slope,
At y = 0 we get the x-intercept, so
0 = m × 2 + 12
m = -12 / 2

A hand tool manufacturer produces a product for which the variable cost is $5.35 per unit and the fixed costs are $16,000. The company sells the product for $8.20 and can sell all that it produces.
In the given scenario, we analyze variable costs, fixed costs, and total costs in a manufacturing context where the business sells a product at a set price and bears specific levels of fixed and variable costs. Average variable cost is obtained by dividing total variable costs by the quantity produced, which impacts the total cost and pricing strategies for the business.
Explanation:The scenario you're describing involves concepts of variable costs, fixed costs, and total costs in the context of a manufacturing business. At zero production, the fixed costs amount to $16,000. These costs do not change regardless of production levels. As production increases, the variable cost, which is $5.35 per unit, is added to the fixed costs. Total cost for any given level of production is the sum of variable and fixed costs. When a company sells the product for $8.20 per unit and can sell all that it produces, it gives us a context to calculate break-even points, profit margins, and other relevant financial metrics.
For example, average variable cost (AVC) is determined by dividing the total variable cost by the quantity of output. If a hypothetical scenario is given where the company produces 80 units, the total variable cost would be 80 units times $5.35, resulting in $428. Therefore, the AVC would be $428/80, which is $5.35 per unit.
As output increases, fixed costs per unit decline because these costs are spread over more units, making the average variable cost a relatively bigger component of the total cost. This principle is crucial for businesses as they plan production and pricing strategies to cover costs and achieve profitability.
Average variable cost cannot be calculated without the quantity of output. The total cost is the sum of fixed costs and variable costs.
Explanation:The subject of this question is and the grade level is
To find the of producing a product, we divide the by the . In this case, the variable cost is $5.35 per unit. To calculate the average variable cost, we need to know the quantity of output. Since the question does not provide the quantity of output, we cannot calculate the average variable cost.
The fixed costs of the hand tool manufacturer are given as $16,000. Fixed costs do not change with the quantity of output. The total cost is the sum of the fixed costs and the variable costs. To calculate the total cost, we would need to know the quantity of output.
Trent hikes up a hill at 4 km/h. He hikes back down at 6 km/h. The hiking trip took 3 hours. How much time did it take Trent to hike up the hill? Write an equation you can use to solve for t, the time it took him to climb up the hill
t = time to hike up the hill
3-t is the time to hike down the hill
so 4t = 6(3-t)
4t = 18-6t
10t = 18
t = 18/10 = 1.8 hours to hike up the hill
1.8 hours = 1 hour 48 minutes
Answer:
The time it took him to climb up the hill is 1.8 hours.
Step-by-step explanation:
Here, t represents the the time it took him to climb up the hill,
Total time taken by it = 3 hours,
Thus, the time taken by it to climb down the hill = ( 3 - t ) hours.
Since, Trent hikes up a hill at 4 km/h,
⇒ Total distance covered by it to climb up = 4 t (Distance = Speed × Time)
Since, Trent go down a hill at 6 km/h,
⇒ Total distance covered by it to go down = 6(3-t)
We know that,
Total distance covered by it to climb up = Total distance covered by it to go down
⇒ 4t = 6(3-t)
Which is the required equation.
⇒ 4t = 18 - 6t
⇒ 10 t = 18
⇒ t = 1.8
Hence, the time it took him to climb up the hill is 1.8 hours.

gas costs $2.53 per gallon in May. In September, gas cost $3.05 per gallon. What was the percent change in the cost of a gallon of gas?
Answer:
20.6%
Step-by-step explanation:
To calculate the percentage of how much increase, we must first know how much is the difference in the price of May with that of September.
That difference will represent how many $ increase the gallon
[tex]3.05-2.53=0.52[/tex]
We know that a $ 0.52 increase now we must calculate to what percentage of the initial price this value is equivalent to know in what percentage the price of May increased.
[tex]2.53 \longrightarrow 100\%\\0.52 \longrightarrow x\\x=\frac{(0.52)(100)}{2.53} \\x=20.6\%[/tex]

Please answer and show the work how you got the answer.
The fraction of the days of the year Regina have fog will be 438.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that, Regina has wet weather on about 3/10 of the days in a year. It has wet weather on about four times as many days as it has fog.
We have to find the fraction of the days of the year Regina have fog,
From the given conditions,
wet weather = 3/10 × days in year
wet weather = 4 × days of fog
Combined both the equation,
3/10 × 365 = 4 × x
x=3×365/10×4
x=438
Thus, the fraction of the days of the year Regina have fog will be 438.
