Examples: 4 check ups / 2 people, 10 dogs / 3 people, 7 computer / 10 people

Each of these shares a common thing. The numerator and denominator have different units.

Well rates are actually comparisons of quantities showing a pattern, (just comparing two quantities would be a ratio :P), and UNIT rates are how much a quantity's supplied per single quantity.
Example; (regular rates), 230/5, 322/7, 414/9.
Well, the unit rate for those 3 examples would be 46/1, because in order to figure how much is provided per unit, you would take one of the examples, and divide the top by the bottom, so like you could take 322 and divide it by 7 to get 46, so that would mean it's 46 per unit. They are all in common because they have the same unit rate, and increased by 2. (230/5), (322/7), and (414/9- you add 2 to 5 to get 7, and 2 to 7 to get 9.)

56 = −8d + 8 there's not multiple answers

ollegr [7]

Answer:

d= -6

Step-by-step explanation:

56 = -8d + 8

1) You want to get d by itself. Subtract 8 from both sides.

56 = -8d + 8

- 8 - 8

(8 - 8 = 0, and 56 - 8 is 48.)

48 = -8d

2) Then, you divide my -8 on both sides.

(48 / -8 is -6, and -8d / -8 is just d.)

-6 = d

So, d = -6

A square pyramid is shown below:

madreJ [45]

Let Surface Area A, a the base edge and h the height:

A = a²+2a√(a²/4+h²)

h=?

pythagorean theorem:

h²=c²-a²

h=√(c²-a²)

h=√(8²-(.7/2)²)= 8

plug it in the above equation A= 11.7ft²

So A is correct

Write a rule for the nth term of the arithmetic sequence: a11= 50, d = 7

ivolga24 [154]

Answer:

Required rule for $n^{th}$ is $a_{n}=7n-27$ .

Step-by-step explanation:

Given that,

$a_{11} = 50,\ \ d=7$

From the question: we have to write the $n^{th}$ term of Arithmetic sequence.

Arithmetic Sequence or Arithmetic progression (A.P) : It is a sequence which possess that difference between of two successive sequence is always constant.

$a_{1} ,a_{2},a_{3},a_{4}.....................a_{n-1},a_{n}$
