Answer:

Simplified it is -1 / 8

Reciprocal is 8/-1 or -8

Step-by-step explanation:

Multiply

7/6 x -3/28

= 7 x -3 / 6 x 28

= -21 / 168

Simplify

-21/21 = -1

168/21 = 8

-21/168 = -1/8

Find reciprocal

The reciprocal of a fraction is the numerator and denominator reversed

-1/8 > 8/-1

8/-1 is the same as -8

Hope this helps!

Answer:

The product of \frac{7}{6} and -\frac{3}{28} is -\frac{1}{8}. The reciprocal is \frac{8}{-1}.

Step-by-step explanation:

We have to find the product of \frac{7}{6} and -\frac{3}{28} before we find the reciprocal.

Before we do this though, we need to review a few words and their definitions.

First, the reciprocal of a fraction is when the numerator becomes denominator and the denominator becomes numerator.

Now we're ready to solve \frac{7}{6} *-\frac{3}{28}:

Step 1: Use this rule: \frac{a}{b} *\frac{c}{d} =\frac{ac}{bd}.

\frac{7*-3}{6*28}

Step 2: Simplify 7 × - 3 to - 21.

\frac{-21}{6*28}

Step 3: Simplify 6 × 28 to 168.

\frac{-21}{168}

Step 4: Move the negative sign to the left.

-\frac{21}{168}

Step 5: Simplify \frac{21}{168} to \frac{1}{8}.

-\frac{1}{8}

Now that we've found the product, we now must find the reciprocal.

Now using what we know and the process to find the reciprocal.

We can use that knowledge to find it:

-\frac{1}{8} =\frac{8}{-1}

Leap years are years in which February has 29 days instead of 28. The device of leap year was invented to keep the calendar in s
goldenfox [79]

Answer:

As you know, a year has around 365 + 1/4 days.

This means that in two years, we have:

365 + 356 + 1/4 + 1/4 = 730 + 1/2

and so on.

adding this up, when we have 4 years we have a full day extra, this is:

1460 + 1

When we divide 1461 by 4, we have 365 with a surpass of 1.

The rule used to keep the calendar in sync with this extra day is adding an extra day to each fourth year.

So each fourth year, we have an extra day in Februray (the Februray 29th), this is called a bisiest year.

The "math rule" used to know if a year is leap or not is:

if a year is not divisible by 4, then it is a common year

else if the year is not divisible by 100 then it is a leap year,

else if the year is not divisible by 400, then it is a common year

if not, the year is a leap year.

Where "year" represents the number of the year.

lord [1]

Answer:

b. 8,800,000.

Step-by-step explanation:

In maria study the number of cars on the road increases by 10% each year.

Total number of cars in the first year =80 million cars.

We will add 10% of 80 million to 80 milion to enable us get the number of cars for the second year.

For year 2 we have;

10% of 80,000,000+80,000,000

\frac{10}{100}*80,000,000+80,000,000

8,000,000 + 80,000,000

88,000,000

number of cars in year 2 = 88 million

We will add 10% of 88 million to 88 milion to enable us get the number of cars for the third year.

\frac{10}{100}*88,000,000+88,000,000

8,800,000+88,000,000

96,800,000

the number of cars on the road in year 3 compared to year 2 will just be the increase which is in BOLD. That is 8,800,000

<em>or simply subtract the number of cars in year 2 from that in year 3;</em>

96,800,000-88,000,000 = 8,800,000

The temperature of the sun is 27 million degrees Fahrenheit. Use scientific notation to express the temperature.
Ipatiy [6.2K]

Answer:

A

Step-by-step explanation:

We know million has 6 zeros.

So, 1 million would be written as:

1,000,000

Similarly, 27 million would be written as:

27,000,000

We know writing a number in scientific notation would make this a decimal in 1 decimal place, so we would select "2.7" as the base of the scientific number.

Now, how many places to the right do we need to go (in 2.7) to make it 27,000,000?

Counting, we see:  7 places

So, power of 10 would be "7", thus we can write:

2.7*10^7

Answer choice A is right
