Arithmetic Sequence

Answers

Answer 1

Answer:18

Step-by-step explanation:

Note: Mathematicians start counting at 1, so by convention, n=1 is the first term. So we must define what the first term is. Then we have to figure out and include the common difference.

Taking a look at the examples again,

Sequence: 1, 2, 3, 4, … | Formula: a(n) = n + 1 | Recursive formula: a(n) = a(n-1) + 1, a(1) = 1

Sequence: 3, 8, 13, 18, … |Formula: b(n) = 5n - 2 | Recursive formula: b(n) = b(n-1) + 5, b(1) = 3

Answers

Answer:15.8

Step-by-step explanation:

After 15.81 seconds the hammer reaches the river if the construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

A construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.

The equation is:

t = √h/4

Plug h = 4000 ft

t = √4000/4

After solving:

t = 15.81 seconds

Thus, after 15.81 seconds the hammer reaches the river if the construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.

find for x

Answers

Answer:

120°

Step-by-step explanation:

The angle next to the x will be 40° due to the alternate angles so

x + 40° + 20° = 180° { being linear pair }

x + 60° = 180°

x = 180° - 60°

x = 120 °

Hope it will help :)

Answer:

120˚

Step-by-step explanation:

Since the two lines are parallel, they are alternate angles

So that means that the angle next to x must be 40˚

So 40 + 20 + x = 180 (since it's half a circle)

60 + x = 180

x = 120

Given the expression 18+9*4-27+9

Using  PEMDAS method

P is for parenthesis

E is for exponents

M is for multiplication

18+(9*4)-27+9

= 18+36-27+9

​Next is Addition

= (18+36)-(27+9)

= 54-36

Then Subtraction

= 54-36

= 18

Hence the required value is 18

becky spends 3/5 of her money she has left £60 left. how much money did she start with?

Answers

Answer: $150

Step-by-step explanation:

And 5 parts = $150

Becky has $150 at first.

Becky starts with $150.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Becky spends 3/5 of her money she has left £60 left.

let Becky earned be x.

so, x- 3/5x= 60

2x/5 = 60

x= 300/ 2

x=$150

Hence, Becky starts with $150.

Brad buys a sandwich. The regular cost is $6. He uses a coupon for 10% off. After that deduction, a sales tax of 5% is added. How much money Brad need to pay for the sandwich?
A. $5.10
B. $5.67
C. $5.94
D. $6.93

Answers

A is the answer to that
The answer is B.

5% of 6.00 = 0.4

6.00 - 0.60 = $5.40

10% of 5.40 = 0.27

5.40 + 0.27 = $5.67
