Round off446,221 to the nearest ten
Answer:
Answer when we round off 446,221 to the nearest ten is 446,220
Step-by-step explanation:
We need to round off 446,221 to the nearest ten.
Nearest ten to the 446,221 can be 446,220 or 446,230
Difference between 446,221 and 446,220 = 446,221 - 446,220 = 1
Difference between 446,221 and 446,230 = 446,230 - 446,221 = 9
Here the difference is minimum for 446,220
Answer when we round off 446,221 to the nearest ten is 446,220
At what points does the curve r(t) = ti + (4t â t2)k intersect the paraboloid z = x2 + y2? (if an answer does not exist, enter dne.)
Final answer:
To find the intersection points of the curve r(t) with the paraboloid z = x^2 + y^2, we substituted the parametric forms into the equation and solved for t, yielding the points (0, 0, 0) and (2, 0, 4).
Explanation:
The student is asking about the intersection points of a curve r(t) with a paraboloid defined by z = x2 + y2. To find these points, we must substitute the parametric forms of x, y, and z from the curve into the equation of the paraboloid and solve for t.
Given the curve r(t) = ti + (4t - t2)k, we can identify the components of the curve as x(t) = t and z(t) = 4t - t2. The y-component is missing, which implies that y = 0. Now, substituting x(t) into the paraboloid equation, we get:
z = x2 + y2
4t - t2 = t2 + 02
By solving for t, we can determine the intersection points. Simplifying the equation, we get:
0 = 2t2 - 4t
Which gives us the solutions t = 0 and t = 2. Substituting these back into r(t) gives the intersection points (0, 0, 0) and (2, 0, 4).
The normal body temperature of a camel is 37°C. This temperature varies by up to 3°C throughout the day. Write and solve an absolute value inequality that represents the range of normal body temperatures (in degrees Celsius) of a camel throughout the day.
The range of normal body temperatures for a camel throughout the day is from 34°C to 40°C, inclusive.
To represent the range of normal body temperatures for a camel throughout the day, we'll use an absolute value inequality. Given that the normal body temperature is 37°C and it varies by up to 3°C, we can express this as:
|T - 37| ≤ 3
Where T represents the temperature of the camel throughout the day. This inequality ensures that the temperature remains within 3 degrees above or below the normal body temperature of 37°C.
To solve this inequality, we'll consider two cases:
1. When T - 37 is positive:
T - 37 ≤ 3
T ≤ 40
2. When T - 37 is negative:
-(T - 37) ≤ 3
-T + 37 ≤ 3
-T ≤ -34
T ≥ 34
Combining the two cases, the range of normal body temperatures for a camel throughout the day is 34°C to 40°C.
the sinclair family live 5.4 miles from southside middle school. how many feet away do they live?
The Sinclair family lives 28,512 feet away from Southside Middle School, calculated by multiplying 5.4 miles by the number of feet in one mile, which is 5,280 feet.
Explanation:The Sinclair family lives 5.4 miles from Southside Middle School. To convert this distance from miles to feet, we use the conversion factor that 1 mile is equal to 5,280 feet. To find the distance in feet, we multiply the number of miles by the number of feet in one mile:
5.4 miles imes 5,280 feet/mile = 28,512 feet.
Therefore, the Sinclair family lives 28,512 feet away from Southside Middle School.

As mentioned in the question, Alex was hired to unpack 576 items of glass wear, at five cents per piece unpacked. For every item broken in the process, however, Alex had to pay $1.98. At the end of the job, Alex received $22.71.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
The total amount earned for 576 glasses is given as,
= 576 × 0.05
= $28.80.
Amount earned = $22.71
Amount paid by Alex for the broken glass = $28.80 - $22.71 = 6.09
Total glass broked = 6.09 / 1.98 ≈ 3
Thus, Alex broke 3 glasses during the unpacking of the glasses.

you invest 1600 in an account that pays an interest rate of 6.5%, what is your balance after 6 years and round your answer to the nearest hundredth.
To calculate the balance after 6 years with compound interest, use the formula Balance = Principal * (1 + Interest Rate)^Time. Substituting the values, we find the balance to be approximately $2,243.89.
Explanation:To calculate the balance after 6 years, we need to use the formula for compound interest:
Balance = Principal * (1 + Interest Rate)^Time
Given that the principal (initial investment) is $1600 and the interest rate is 6.5%, we can substitute these values into the formula:
Balance = 1600 * (1 + 0.065)^6
Calculating this, we find that the balance after 6 years is approximately $2,243.89.
The balance after 6 years is approximately $2105.69.
Explanation:To find the balance after 6 years, we can use the formula for compound interest:
Balance = Principal(1 + Interest Rate)^Ti
Plugging in the given values, we have:
Balance = $1600(1 + 0.065)^6
Simplifying, we get:
Balance = $1600(1.065)^6
Calculating, we find that the balance after 6 years is approximately $oxed{2105.69}.

A pile of coins, consisting of quarters and half dollars, it worth $11.75. If there are 2 more quarters than half dollars, how many of each are there?
Let the number of half dollars be x,
number of quarters = x + 2
amount of half dollars = 0.5x
amount of quarters = 0.25(x + 2)
= 0.25x + 0.5
total amount = 0.5x + 0.25x + 0.5
= 0.75x + 0.5
0.75x + 0.5 = 11.75
0.75x = 11.25
x = 15
number of quarters = x + 2
= 15 + 2
= 17
There are 17 quarters and 15 half dollars.
