Will give brainlyMr. Brown is riding his bicycle along a road that is 1 Kilometer long. Both wheels are 1 meter in diameter.
How many times does each wheel revolve on his journey of 1 Kilometer?

Answer:

3/4 or 6/8

Step-by-step explanation:

the thumbtack goes to 12/16 on the ruler which can be simplified to 3/4 or 6/8.

Final answer:

To measure a thumbtack to the nearest 1/8 inches, use a finely calibrated ruler. Position the thumbtack against the ruler, starting from zero, and note the measurement closer to nearest 1/8 of an inch.

Explanation:

To measure the Thumbtack to the nearest 1/8 inches, one would have to use a fine-grained ruler, preferably one calibrated with 1/8 inch gradations. Measurement is the process of determining the size or distance of an object and it requires appropriate measuring tools.

So, if you were for instance measuring a thumbtack, the measurement process would involve positioning the zero end of your ruler at one end of the thumbtack and noting the length at the other end. The length of a thumbtack should typically be less than an inch, hence why a finely calibrated ruler is required. Depending on the precision of your ruler, the thumbtack's length may be closer to one gradation than the other. In this case, always round to the nearest 1/8 inch that the thumbtack's length is closer to.

For example, if the thumbtack measures between 3/8 and 4/8 inch (or 1/2 inch), and it is closer to 3/8, then the measurement to the nearest 1/8 inch should be recorded as 3/8 inch.

The round off value of 16311 is

what is rounding off?

Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.

Given:

16311.

Now,

To round off nearest thousand focus on the place value of hundred place value.

Now, focus the value on hundred place value is less than 5 or greater than 5.

As, the number is less than 5 it will go towards previous number.

The round will lie between 16000 and 17000.

hence, the round off will be 16000.

Answer:

-3

Step-by-step explanation:

find two points on the line are exact on the grid,

the one （4, -10）,

the another （-1,5）,

then the slope is：

（-10-5）/（4-（-1））

=-15/5

Rasheed needs to wash 20 cars as washing 19 cars won't be $231.

What is an equation?

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, Rasheed needs to save $231 to earn money he plans to wash cars and charge $12 per car.

Assuming no. of cars he needs to wash is x.

∴ 12x = 231.

x = 231/12.

x = 19.25.

But he needs to wash 20 cars to meet his needs.
