Given that 41 to the second power= 1681 find the square of 410
The square of any number is simply that number multiplied by itself. Thus the square of 410 is 410 multiplied by 410, which equals 168100.
Explanation:The concept being asked here is the squaring of exponentials. 'To square' a number encompasses multiplying that number by itself. Hence 41 to the second power, or 41 squared, equals 1681 as the question states. By the same logic, to find the square of 410, we would multiply 410 by itself. That calculation will give the result as 168100. The square of 410 is 410 multiplied by 410, which equals 168100. Thus, the square of 410 equals 168,100.

a digital scale measures weight to the nearest 0.2 pound. which measurement shows an appropriate level of precison for the scale?
A. 130.4 pounds
B. 125 pounds
C.120 pounds
D. 124.75 pounds
Answer:
130.4 pounds
Step-by-step explanation:
The digital scale is measuring weight to the nearest 0.2 pounds, so basically the digital scale would show you the weight of an object that is a multiple of 0.2.
Talking about precision, precision tells us how accurate is the measured value or how close is the measured value to the actual value.
Here, scale is measuring to the nearest 0.2 pounds, so out of the given values the measurement that shows an appropriate level of precision for the scale is 130.4 pounds.
A gram of gasoline produces 45.0kj of energy when burned. gasoline has a density of 0.77/gml . how would you calculate the amount of energy produced by burning 46.l of gasoline? set the math up. but don't do any of it. just leave your answer as a math expression. also, be sure your answer includes all the correct unit symbols.
To calculate the amount of energy produced by burning 46.1 mL of gasoline, you can use the formula: Amount of energy = (Density of gasoline) x (Volume of gasoline) x (Energy produced per gram). Plug in the values and include the correct unit symbols (g/mL, mL, kJ) in your answer.
Explanation:To calculate the amount of energy produced by burning 46.1 mL of gasoline, you can use the following formula:
Amount of energy = (Density of gasoline) x (Volume of gasoline) x (Energy produced per gram)
Plugging in the values:
Amount of energy = (0.77 g/mL) x (46.1 mL) x (45.0 kJ/g)
This gives us the math expression:
Amount of energy = 0.77 x 46.1 x 45.0 kJ
Make sure to include the correct unit symbols (g/mL, mL, kJ) in your answer.

Solve for x
3j = 4kx + 7mx + n
Answer:
[tex]x=\frac{3j-n}{4k+7m}[/tex]
Step-by-step explanation:
We have the expression [tex]3j=4kx+7mx+n[/tex] and we have to solve for x, this means that we have to clear x.
Then first we are going to subtract n in both sides of the equation,
[tex]3j=4kx+7mx+n\\3j-n=4kx+7mx+n-n\\3j-n=4kx+7mx[/tex]
Now in the right side we can apply common factor x.
[tex]3j-n=(4k)x+(7m)x\\3j-n=x(4k+7m)[/tex]
For the last step divide both sides of the equation in (4k+7m),
[tex]3j-n=x(4k+7m)\\\\\frac{3j-n}{4k+7m}=\frac{x(4k+7m)}{(4k+7m)} \\\\\frac{3j-n}{4k+7m}=x[/tex]
Then,
[tex]x=\frac{3j-n}{4k+7m}[/tex]
A number is multiplied by 4, and then 6 is added to the product. The result is 18. What is the number? I already know that the answer is 3 but I have to check my answer. How do I check it?
The student can check the accuracy of their answer by substitifying their solution back into the equation. If both sides of the equation are equal after the substitution, then the solution is correct and 4 * 3 + 6 does in fact equal 18 in this case.
Explanation:The subject of your question is to solve a simple equation and you want to check your answer. The equation you're talking about can be expressed as 4x + 6 = 18, where x is the number you're trying to find. You said you believe x = 3, and we can check that by substituting 3 for x in the equation and seeing if both sides match.
On the left side of the equation, 4x + 6 would become 4 * 3 + 6, which equals 12 + 6 = 18. The right side of the equation is also 18, so your answer of x = 3 is correct!
Substituting your answer back into the equation is a solid strategy to check your answers in mathematics.

Suzi starts her hike at -225 feet below sea level. When she reaches the end of the hike, she is still below sea level at -127 feet. What was the change on elevation from the beggining of Suzi's hike to the end of the hike?
The change in elevation from the beginning of Suzi's hike to the end is 98 feet, as calculated by the difference in starting and ending elevations: (-127) - (-225) = 98 feet.
To calculate the elevation change, we subtract the elevation at the start of the hike from the elevation at the end of the hike. Suzi started at -225 feet below sea level and ended at -127 feet below sea level.
To find the change in elevation, we perform the following calculation:
Write down the starting elevation: -225 feet.
Write down the ending elevation: -127 feet.
Subtract the starting elevation from the ending elevation: (-127) - (-225).
Simplify the equation by adding: -127 + 225 = 98 feet.
Therefore, the change in elevation from the beginning of Suzi's hike to the end is 98 feet. The positive result indicates an increase in elevation, even though Suzi is still below sea level at the end of her hike.

55 miles per hour write a algebric expression to show how far the car will travel in a certain number of hours
The algebraic expression for the scenario is 'd = 55t', where 55 (miles per hour) is the constant, and 't', which represents time in hours, is the variable. This expression is used to calculate the distance traveled by a car.
Explanation:The subject of your question is algebra, particularly involving the concept of linear equations. In this scenario, you're looking to determine how far a car will travel given a certain speed and number of hours. Your constant in this case will be the speed of the car, which is 55 miles per hour. The variable is the time in hours, which we can denote by 't'. Hence, the algebraic expression representing this scenario would be d = 55t where 'd' represents the distance traveled by the car.

It is same as equation (1). Since equation (1) and (2) are same, therefore all the points lies on the line or which satisfies the equation are the solution of the given system of equations.
Test the points whether the point lies on the line or not.
Check for point A(6,-7).
[tex]2(6)+(-7)=5[/tex]
[tex]5=5[/tex]
LHS and RHS are equal, therefore the point A is the solution of the system of equations.
