A group of tourists spend $168 to rent snorkels and find. A total of 10 snorkels and 12 pairs of fins are rented. Renting a snor
WITCHER [35]

Answer:

Cost to a rent a snorkel=\$ 12                ,           Cost on 10 rent  snorkel =\$ 120

Step-by-step explanation:

Given,

Tourist spend on rent snorkel and fin=\$ 168

10 snorkel and 12 pairs of fin

Let the cost to  rent a snorkel be =\$x

and cost of a pair of fin is =\$y

x=3y            (given condition)

10x+12y=168

10\times 3y+12y=168

30y+12y=168

42y=168

y=168/42

y=4

Cost of a pair of fin=  y=\$ 4

x=3y

x=3\times 4

x=12

Cost of rent a snorkel=\$ 12

Total cost of a rent snorkel

=10\times 12

   =\$ 168

A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so
mamaluj [8]

Answer:

1) Is the pattern an arithmetic sequence?​

Yes it is

2)Identify a and d.​

a = First term = 2

d = Common difference = 2

3) Write the 50th term of the sequence.​

50th term = 100

4) Find the total number of logs in the first 10 rows.​

= 1010 logs

Step-by-step explanation:

Is the pattern an arithmetic sequence?​

Yes it is

2) Identify a and d.​

A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so on,

The formula for arithmetic sequence =

an = a+ (n - 1)d

a = First term

d = Common difference

For the above question:

a = 2

d = Second term - First term

= 4 - 2

d = 2

3) Write the 50th term of the sequence.​

Using the formula for arithmetic sequence

an = a+ (n - 1)d

a = 2

n = 50

d = 2

a50 = 2 + (50 - 1)2

= 2 + (49)2

= 2 + 98

= 100

The 50th term = 100

4)Find the total number of logs in the first 10 rows.​

Sum of first n terms = n/2(a + l)

n = 10

a = first term = 2

We are told that there are 200 logs in the bottom row, hence:

l = last term = 200 logs

Hence,

Sn = 10/2×[ (2 + 200

= 5(202)

= 1010 logs

3 (x+2)+9<6(x-3) solve the inequality and write the solution using interval notation​
Darya [45]

Answer:

(11, ∞).

Step-by-step explanation:

3 (x+2)+9<6(x-3)

3x + 6 + 9 < 6x - 18

-3x < -18 - 6 - 9

-3x < -33

x > 11       (Note the inequality flips as we are dividing by a negative value).
