a store is having a 20% off sale on all merchandise. if mai buys one item and saves $13, what was the original price of her purchase

Step-by-step explanation:

For a

Let the another angle be x then

x + 51° = 90° {being complementary angles }

x = 90° - 51°

x = 39°

For b

Let the another angle be x then

x + 113° = 180° {being supplementary angles }

x = 180° - 113°

x = 67°

Answer:

2(3)+

Step-by-step explanation:

just multiply the divider by the numerator

Answer:

Answers:

14 + 18 ÷ 2 x 18 – 7 = 169

60 – 9 x 8 ÷ 8 x 6 = 6

15 x 10 + 12 ÷ 3 + 9 = 163

(10 ÷ 5)3 + 100 – 9 x 11 = 7

8 x 4 + 9 – 9 + 18 = 50

3 x 8 x 2 – 42 + 5 = 11

i hope this helps, good luck :)

Answer:

Step-by-step explanation:

14 + 18 ÷ 2 x 18 – 7 = 169

14 + 9 * 18 - 7

14 + 162 - 7

169

60 – 9 x 8 ÷ 8 x 6 = 6

60 - 72 / 8 * 6

60 + -216/4

60 - 54

6

15 x 10 + 12 ÷ 3 + 9 = 163

150 + 12 / 3 + 9

150 + 4 + 9

163

(10 ÷ 5)3 + 100 – 9 x 11 = 7

2 * 3 + 100 - 9 * 11

6 + 100 - 99

7

8 x 4 + 9 – 9 + 18 = 50

32 + 9 - 9 + 18

41 - 9 + 18

32 + 18

50

3 x 8 x 2 – 42 + 5 = 11

24 * 2 - 42 + 5

48 - 42 + 5

11

Answer:

The markup percentage was 135%.

Step-by-step explanation:

In order to find the markup percent, you have to take the sales price minus the cost and divide that by the cost. Then, you have to multiply by 100 to establish the markup percentage:

markup percentage=((19.95-8.50)/8.50)*100

markup percentage=(11.45/8.50)*100

markup percentage=135%

According to this, the answer is that the markup percentage was 135%.

Answer:

150 pizzas

Step-by-step explanation

36 pizzas are equivalent to 24% so i divided both sides by 4 which gave me 9 pizzas  for 6% . But 6 cannot fully fit into 100 so it will have to be a decimal i did 100 divided by 6 so i would know what i would have to divide both sides by which gave me  50/3 which was 16.66666667 which when i times by 9 by it gave me 150 pizzas

5) x = 12 6) y = 3.5

Step-by-step explanation:

For number 6 that one may be right I tried several ways and kept getting that answer

5. is completely write though

Hope that helps

Answer:

Question 5: x = 12, Question 6: y = 2[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Use the Pythagorean Theorem to calculate missing sides.

Question 5 explanation: [tex]x^{2} + 9^2 = 15^2[/tex]n:  ⇒ [tex]x^{2} + 81 = 225[/tex] ⇒ [tex]x^{2} = 144[/tex] ⇒ [tex]x=12[/tex]

Question 5 explanation: [tex]y^{2}+6^2 =(4\sqrt{3})^2[/tex] ⇒ [tex]y^{2} + 36 = 48[/tex] ⇒ [tex]y^2 = 12[/tex] ⇒ [tex]y=2\sqrt{3}[/tex]

Answer:

Cannot be determined

Step-by-step explanation:

You cannot assume the function travels down infinitely, because the function is not given to you. The graph could go up down left or right for all you know, you just cannot see it.

Answer:

x= - 9

Step-by-step explanation:

Hey there!

Use the Distributive Property and simplify:

-8(x+7)=16

-8x-56=16

Notice we write -8 right next to x.

Add 56 to both sides:

-8x=16+56

-8x=72

Divide both sides by -8:

x=-9

Hope everything is clear.

Let me know if you have any questions!

Answer:

Pack of 6

Step-by-step explanation:

Pack of 4 = £1

Packs of 6 = £1.20

Price per unit of each pack:

Pack of 4 ;

Unit price : cost / units

Unit price = £1 / 4 = £0.25

Pack of 6 ;

Unit price : cost / units

Unit price = £1.20 / 6 = £0.20

Pack of 6 is the best value for money as it has a lower unit price

Answer:

3/10

Step-by-step explanation:

because if you use a calculator that answer would be 0.9 which is 9/10 as a decimal and if u did it yourself then you would do 1/3 x 9/10 and you would get 9/30 which is 3/10 if u simplify it

Answer:

x = 84

Step-by-step explanation:

The sum of the angles around a point = 360°

sum the given angles and equate to 360

x + 132 + 54 + 90 = 360

x + 276 = 360 ( subtract 276 from both sides )

x = 84

Answer:

x = 84°

Step-by-step explanation:

→ Recall the fact that angles around a point add up to 360°

360 - (90 + 54 + 132 ) = x

→ Simplify

360 - 276 = x

→ Simplify again

84 = x ∴ x = 84°

Answer:

38.57 feets

Step-by-step explanation:

Given that:

Height of monument, h = 300ft

Shadow of monument, s = 210 ft

Shadow of tree, s = 27ft

Height of tree, = x

Using the relation :

Height / shadow = height / shadow

Monument = tree

300 / 210 = h / 27

Cross multiply

300 * 27 = 210 * h

8100 = 210h

h = 8100 / 210

h = 38.57 feets
