1 answer:
Sindrei [870]3 years ago
5 0

Answer:

3 3/5 + 1 1/4 = <u>4 17/20</u>

7/8 + 1/12 =<u> 23/24</u>

8/9 - 2/5 = <u>22/45</u>

5 1/4 - 2 2/3 = <u>2 7/12</u>

Step-by-step explanation:

3 3/5 + 1 1/4

First convert into improper fractions

= 18/5 + 5/4

Now find the common denominator

72/20 + 25/20 =

97/20

Now simplify

4 17/20

<u>Next problem:</u>

7/8 + 1/12

find the common denominator

21/24 + 2/24 =

23/24

<u>Next problem:</u>

8/9 - 2/5

find the common denominator

40/45 - 18/45 =

22/45

<u>Next problem:</u>

5 1/4 - 2 2/3

First convert into improper fractions

21/4 - 8/3

find the common denominator

63/12 - 32/12 =

31/12

Now simplify

2 7/12

Using the expansion for the binomial: ( x^3 − y^4 )^9 :The coefficient for the 6th term is
Lelechka [254]

Answer:

-126

Step-by-step explanation:

For the binomial expression  (a-b)^{n} the coefficient of (r+1)^{th} term is given by {n \choose r} \times -1^{(r)}.

We have to find the coefficient of 6th term in the binomial expansion of

(x^{3}-y^{4})^{9}.

Hence n=9 and r=5

The coefficient of 6th term = {9 \choose 5} \times (-1)^{5}

                                             = -{9 \choose 5}

                                             = -126

A planet's initial height is 7 inches tall . The plant grows 1.3 inches each day for 27 days before the plant falling over 0.5 i
hodyreva [135]

Answer:

40.6 inches

Step-by-step explanation:

The plant's initial height is 7 inches tall.

It grows 1.3 inches each day for 27 days. This means that after 27 days, it must have grown an extra:

1.3 * 27 = 35.1 inches

It must have grown an extra 35.1 inches after 27 days. Therefore, its new height after 27 days is:

7 + 35.1 = 42.1 inches

The plant then begins falling over 0.5 inch for the next 3 days. After 3 days, it must have fallen over by a height:

0.5 * 3 = 1.5 inches

Therefore, after 30 days, the plant's new height is:

42.1 - 1.5 = 40.6 inches

The plant's height after 30 days is 40.6 inches
