Answer:

There are 77  \frac{2}{7}s

Step-by-step explanation:

You can calculate this by a series of flips and operation changes.

Step 1 - Change 22 into a fraction

\frac{22}{1}

Step 2 - Flip the operation, in this case, it will be from division to multiplication:

\frac{22}{1} * \frac{2}{7}

Step 3 - Flip the second fraction

\frac{22}{1} * \frac{7}{2}

Step 4 - Multiply the two fractions together:

\frac{22 * 7}{1 * 2} =  \frac{154}{2}

Step 5 - Divide the numerator by the denominator:

154 ÷ 2 = 77

So 22 has 77  \frac{2}{7}s in it.

Hope this helps!

Which statement best compares the value of the 4 in each of these numbers? A: 16.942 B: 9.214 A) (40 < 400) The value of the
OleMash [197]

First, let us write the place values of 4 in A and B.

In A, the number is 16.942 and the place value of 4 is 0.04.

In B, the number is 9.214 and the place value of 4 is 0.004.

It is clear that 0.04 > 0.004.

Hence, statement C best compares the value of 4 in each number.

Which of the following is a geometric series? 40 + 50 + 60 + 70 40 + 42 + 44 + 46 40 + 80 + 40 + 120 40 + 20 + 10 + 5
Aloiza [94]

Answer:

40 + 20 + 10 + 5 is a geometric series

Step-by-step explanation:

* Lets revise the geometric series

- There is a constant ratio between each two consecutive numbers

- Ex:

# 5  ,  10  ,  20  ,  40  ,  80  ,  ………………………. (×2)

# 5000  ,  1000  ,  200  ,  40  ,  …………………………(÷5)

* General term (nth term) of a Geometric Series:

∵ U1 = a  ,  U2  = ar  ,  U3  = ar2  ,  U4 = ar3  ,  U5 = ar4

∴ Un = ar^n-1, where a is the first term , r is the constant ratio

  between each two consecutive terms , and n is the position of

  the term in the series

* Now lets check the answers to find the correct one

# 40 + 50 + 60 + 70

∵ 50/40 = 5/4

∵ 60/50 = 6/5

∵ 5/4 ≠ 6/5

- No common ratio between each two consecutive terms

∴ Not geometric series

# 40 + 42 + 44 + 46

∵ 42/40 = 21/20

∵ 44/42 = 22/21

∵ 21/20 ≠ 22/21

- No common ratio between each two consecutive terms

∴ Not geometric series

# 40 + 80 + 40 + 120

∵ 80/40 = 2

∵ 40/80 = 1/2

∵ 2 ≠ 1/2

- No common ratio between each two consecutive terms

∴ Not geometric series

# 40 + 20 + 10 + 5

∵ 20/40 = 1/2

∵ 10/20 = 1/2

∵ 5/10 = 1/2

- There is a common ratio between each two consecutive terms

∴ 40 + 20 + 10 + 5 is a geometric series
