The multiplications between (-1.15) and  3.2 will be negative of 3.68.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

WE need to find the multiplications between (-1.15) and  3.2

We now that when multiplying, when the signs are different, the result will be negative.

(-1.15) x 3.2 = -3.68

Therefore, the multiplications between (-1.15) and  3.2 will be negative of 3.68.

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.

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. The distance is calculated by multiplying the constant speed by the variable time.

Aling Luding will need 23.75 meters of cloth to make 25 pillowcases, with each pillowcase requiring 95 cm of cloth. We convert the total centimeters to meters by dividing by 100.

To calculate the total amount of cloth Aling Luding needs to make 25 pillowcases, with each pillowcase requiring 95 cm of cloth, we need to perform a simple multiplication. We multiply the number of pillowcases by the length of cloth needed per pillowcase.

Therefore, the calculation will be:

25 pillowcases  imes 95 cm per pillowcase = 2375 cm.

However, we often measure fabric in meters, so we need to convert centimeters to meters. There are 100 cm in a meter, so:

2375 cm \/ 100 = 23.75 meters.

So, Aling Luding needs 23.75 meters of cloth in total to make 25 pillowcases.

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.

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.

Answer:

Round to the nearest tenth  336.752 divided by 31 is 10.9

Step-by-step explanation:

Consider the provided information.

336.752 divided by 31

This can be written as:

336.752 ÷ 31

Divide the number as shown:

[tex]\frac{336.752}{31}[/tex]

[tex]10.862968[/tex]

Now we need to round it to the nearest tenth.

According to the place value:

Tens   Ones   Decimal point   Tenths   Hundredths

 10         1                    .                0.1           0.01

According to place value tenths place is just after the decimal point so round the number to just after decimal point.

The rule of rounding a number is:

If 0, 1, 2, 3, or 4 follow the number, then no need to change the rounding digit.

If 5, 6, 7, 8, or 9 follow the number, round it up by one number.

Here, the number at the hundredths place is 6 so round it up.

Thus, the  round to the nearest tenth is 10.9

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.

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.

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.

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.
