Cost of a dozen pens is ₹ 180 and cost of 8 ball pens is ₹ 56. Find the ratio of the

cost of a pen to the cost of a ball pen. [1 ½ m]

​

Answers

Answer 1

Answer:

Ratio of cost of a pen to cost of a ball pen is 15:7

Step-by-step explanation:

Given that:

Cost of dozen pens = ₹180

Unit rate = [tex]\frac{180}{12}[/tex]

Unit rate = ₹ 15 per pen

Cost of 8 ball pens = ₹ 56

Unit rate = [tex]\frac{56}{8}[/tex]

Unit rate = ₹7 per ball pen

Ratio of cost of a pen to cost of a ball pen,

15 : 7

Hence,

Ratio of cost of a pen to cost of a ball pen is 15:7

(x, y ) → (x + 10, y + 10 )

Step-by-step explanation:

Consider the coordinates of C and C'

C(- 7, - 1 ) and C'(3, 9 )

The translation in the x- direction is

- 7 → 3 = 3 - (- 7) = 3 + 7 = 10

The translation in the y- direction is

- 1 → 9 = 9 - (- 1) = 9 + 1 = 10

Then translation rule is

(x, y ) → (x + 10, y + 10 )

The store offers a 35% discount. If the regular price of an item is x dollars, what is the discount price in dollars?

Answers

Answer: .35x

Step-by-step explanation:

take the 35% and turn it into a decimal (.35)

Since the item is "X" dollars, multiply the x(.35)

This gives you .35x

Answer:

If there is a 35% discount, first convert the percent to a decimal

35% = 0.35

Then multiply the discount rate by the price of the item

x = item price

0.20x = discounted price

Solve for N,

−2p + 6n = 5

Answers

Answer:

[tex]n=\frac{1}{3}p+\frac{5}{6}[/tex]

Step-by-step explanation:

In this question, you are solving for n.

Solve:

−2p + 6n = 5

We have to get "n" by itself, so add 2p to both sides.

6n = 2p + 5

Since the variable "n" has a number next to it, we have to get rid of that number in order to get our answer.

To do so, we would divide both sides by 6.

[tex]n=\frac{2}{6}p+\frac{5}{6}[/tex]

Simplify the equation further.

[tex]n=\frac{1}{3}p+\frac{5}{6}[/tex]

Answers

Answer:

x = 13°

Step-by-step explanation:

Check the diagram attached below to see how the angles labelled A and B, which are interior angles of the triangle where x is found.

Let's find the measure of angle A and angle B.

m<A = 85° (vertical angles are congruent)

m<B = 180° - 98° = 82° (corresponding angles/supplementary angles)

Thus:

x + A + B = 180° (sum of interior angles of a ∆)

x + 85° + 82° = 180° (substitution)

x + 167 = 180

x = 180 - 167 (Subtraction property of equality)

x = 13°
