For number 2. The pilot flew 4 circuits and in total by the 5th day he flew 14 right?
Alchen [17]3 years ago

Answer:

1) first term = 2

Step-by-step explanation:

1)  n =14 ;   d = 6 ;  Sum = 574

    Sum =n/2 * (2a + (n-1)d)

     574 = 14/2 * (2a + (14-1) * 6)

     574   = 7 * (2a + 13 * 6)

  574   = 7 * (2a +  78)

   574/ 7 = 2a + 78

     82    = 2a + 78

 82 - 78 = 2a

   4 = 2a

 a = 4/2

a =2

2) No.of circuits on first day = 14 - 12  = 2 circuits

Total by the end of fifth day  = 2 + 5 +8 +11 +14 = 40

3) n = 20 ;   a = 32768

  r = term 2  / term 1 = 16384 / 32768 = 1/2

 nth term = ar^(n-1)

20th term = 32768 * (1/2)^19

                 = 32768 * (1/ 524288)

                 = 32768 / 524288

                  = 1/16

Jackson had 1, 3/8 kg of fertilizer he used some to fertilize a flower bdd and he only had 2/3kg left how much fertilizer was us
ddd [48]

Answer:

Jackson had 1, ⅜ kg of fertilizer he used some to fertilize a flower bed and he only had ⅔ kg left how much fertilizer was used in the flower bed

Step-by-step explanation:

The calculator performs basic and advanced operations with fractions, expressions with fractions combined with integers, decimals, and mixed numbers. It also shows detailed step-by-step information about the fraction calculation procedure. Solve problems with two, three, or more fractions and numbers in one expression.

1/3 * (1/2 - 3 3/8) = -23/

24

≅ -0.9583333

Spelled result in words is minus twenty-three twenty-fourths.

How do you solve fractions step by step?

Conversion a mixed number 3 3/

8

to a improper fraction: 3 3/8 = 3 3/

8

= 3 · 8 + 3/

8

= 24 + 3/

8

= 27/

8

To find new numerator:

a) Multiply the whole number 3 by the denominator 8. Whole number 3 equally 3 * 8/

8

= 24/

8

b) Add the answer from previous step 24 to the numerator 3. New numerator is 24 + 3 = 27

c) Write a previous answer (new numerator 27) over the denominator 8.

Three and three eighths is twenty-seven eighths

Subtract: 1/

2

- 27/

8

= 1 · 4/

2 · 4

- 27/

8

= 4/

8

- 27/

8

= 4 - 27/

8

= -23/

8

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 8) = 8. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 8 = 16. In the next intermediate step the fraction result cannot be further simplified by canceling.

In words - one half minus twenty-seven eighths = minus twenty-three eighths.

Multiple: 1/

3

* the result of step No. 2 = 1/

3

* (-23/

8

) = 1 · (-23)/

3 · 8

= -23/

24

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(-23, 24) = 1. In the next intermediate step the fraction result cannot be further simplified by canceling.

In words - one third multiplied by minus twenty-three eighths = minus twenty-three twenty-fourths
