11<br> The 7th term of Ap is 27 and the 12th term is 47.what is the sequence
inessss [21]

Answer:

3, 7, 11, 15, 19, 23, 27,.......

Step-by-step explanation:

Let the first term and the common difference of the AP be a and d respectively.

a_7 = 27 .....(given)

Therefore,

a + (7- 1) d = 27

a + 6d = 27

a = 27 - 6d...... (1)

a _{12} = 47.....(given)

Therefore,

a + (12 - 1) d = 47

a + 11d = 47......(2)

From equations (1) & (2)

27 - 6d + 11d = 47

24 + 5d = 47

5d = 47 - 27

5d = 20

d = 20/5

d = 4

Plug d = 4 in equation (1) we find:

a = 27 - 6*4

a = 27 - 24

a = 3

Therefore,

a_1 = a = 3

a_2 = a_1 + d= 3 + 4 = 7

a_3 = a_2 + d= 7 + 4 = 11

a_4 = a_3 + d= 11 + 4 = 15

a_5 = a_4 + d= 15 + 4 = 19

a_6 = a_5 + d= 19 + 4 = 23

a_7 = a_6 + d= 23 + 4 = 27

Thus, the sequence is: 3, 7, 11, 15, 19, 23, 27,.......

Triangles IJK and LMN are similar. Find y using proportions. Explain and show all your steps.
Deffense [45]

Triangles IJK and LMN are similar. Then, the proportion between their similar sides must be equal. That is:

IJ/ML = JK/MN = IK/LN

where:

IJ = x

JK = 54

IK = y

MN = 42

ML = 28

NL = 35

In order to find the value of y, you consider the equation JK/MN = IK/LN, and solve for y, just as follow

JK/MN = IK/LN replace by the values

54/42 = y/35 multiply both sides by 35

(54/42)(35) = y

45 = y

Hence, y = 45

34kurt

Answer:

Kohl = $42

Target = $51.30

Best deal is at Kohl's

Step-by-step explanation:

Given ;

At Kohl's:

Selling price = $60

Friend's and family discount = 30% off

(100 - 30)% * $60

0.7 * 60 = $42

At target :

Purchase price = $38

Markup = 35%

Selling price = (100 + 35)% * $38 = 1.35 * 38 = $51.3

Mrs. Clason will get the best deal at Kohl's.
