To divide 7.24 by 7 and round to the nearest tenth, you divide 7.24 by 7, which gives you approximately 1.034285714. The final answer, rounded to the nearest tenth, is 1.0.

To divide 7.24 by 7 and round to the nearest tenth, we divide 7.24 by 7, which gives us approximately 1.034285714. To round to the nearest tenth, we look at the digit in the hundredths place, which is 4. Since 4 is less than 5, we do not round up. Therefore, the final answer, rounded to the nearest tenth, is 1.0.

Final answer:

The division of 7.24 by 7 results in 1.0342857. Rounding this to the nearest tenth, considering the value in the hundredths place is less than 5, the final answer is 1.0.

Explanation:

The question of 7.24 divided by 7 rounded to the nearest tenth deals with basic division and rounding numbers. When you divide 7.24 by 7 using a calculator, you get 1.0342857. To round this to the nearest tenth, we look at the number directly after the tenths place, which is 3 (in the hundredths place). Since 3 is less than 5, we do not round up. Therefore, the answer is 1.0 when rounded to the nearest tenth.

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.

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.

Final answer:

To calculate the total cost of repairs to Mr. Estes's car, add the fixed cost of parts ($48) to the labor cost ($40 per hour for 1.5 hours), resulting in a total cost of $108.

Explanation:

To find the total cost, we need to consider both the fixed cost (cost of parts) and the variable cost (mechanic's labor charged per hour).

The fixed cost for parts is $48, and the mechanic charges $40 per hour.

If the mechanic works for 1.5 hours, we can calculate the total cost using the equation:

Total Cost = Cost of Parts + (Hourly Rate × Hours Worked).

Substituting the given values into the equation, we get:

Total Cost = $48 + ($40 × 1.5)

= $48 + $60

= $108

Therefore, the total cost of repairs to Mr. Estes's car is $108.

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

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.

Answer is: d=20.
