Answer:
Step-by-step explanation:
R = report length
R = 40 + (3/8)R + (1/3)R
3/8 = 3*3/8*3 = 9/24
1/3 = 8*1 / 3*8 = 8/34
R = 40 + (9/24)R + (8/24)R
R = 40 + (17/24)R Subtract 17/24 from the left
R-17/24 R = 40
7/24 R = 40 Multiply both sides by 24
7R = 40 * 24
7R = 960 Divide by 7
R = 960/7
R = 137.1 which breaks the rounding rule and becomes 138 because something has to be typed on page 138
Answer:
47, 40, 33, 26 are the first four terms of the sequence.
Step-by-step explanation:
Expression representing the sequence is,
where n = number of term in the sequence
For n = 1,
= 47
For n = 2,
= 47 - 7
= 40
For n = 3,
= 47 - 7(3 -1)
= 47 - 14
= 33
For n = 4,
= 47 - 21
= 26
Therefore, first four terms of the sequence are 47, 40, 33 and 26.
This is a tricky question that Reina and Sam are multiplying (84)5 (73)9and their work are (84)5 (73)9 = 84 + 573 + 9 = 89712 Reina's(84)5 (73)9 = 84⋅573⋅9 = 820727 Sam'sActually they are doing or multiplying using exponents.
Reina’s work (8⁴)₅(7³)⁹=8⁴⁺⁵+ 7³⁺⁹= 8⁹ 7¹²This is incorrect because she added exponents instead of multiplying exponents
Sams work (8⁴)⁵ (7³)⁹=8⁴ˣ⁵ 7³ˣ⁹= 8²⁰ 7²⁷This is correct because Sam multiplied exponents correctly
Exponents are multiplied not added.
