Answer:

∠BXY = 150

∠BXZ = 30

∠AXZ = 150

Step-by-step explanation:

∠AXY and ∠BXY are adjacent angles

∠AXY + ∠BXY = 180 {linear pair}

30 + ∠BXY = 180

∠BXY = 180 - 30 = 150

∠AXZ = ∠BXY {Vertically opposite angles}

∠AXY = 150°

∠BXZ = ∠AXY {Vertically opposite angle}

∠BXZ = 30°

A clock store sold a certain clock to a collector for 20 percent more than the store had originally paid for the clock. When the

olga nikolaevna [1]

Answer: Option (A)

Step-by-step explanation:

Let the original price of the clock be "x "

The clock is then resold to a collector = x + 20% of "x "

= x + 0.2x

= 1.2x

Now, the shop re-buy the clock at a price = $Reselling\ price \times 0.50$

$= 1.2x \times 0.5$

= 0.6x

Therefore,

Original Cost - Buy-Back price = $100

⇒ x - 0.6x = 100

⇒ x = 250

Hence , the selling price of the clock for the second time is

$= 1.8\times0.6\times250$

= $270

Answer:

i) Sally' s grocery bill = c - $\frac{5}{100}$ c = 0.95c

Therefore the correct option is B.)

ii) Therefore the expression which represents the expected population

next year is given by :

= p + $\dfrac{7.5}{100}$ p = 1.075p

Therefore the correct option is B.)

Step-by-step explanation:

Sally has a discount card that reduces the price of her grocery bill in a certain grocery store by 5%.

Let c represent the cost of Sally's groceries.

therefore the expression which represents Sally's grocery bill is given by :

Sally' s grocery bill = c - $\frac{5}{100}$ c = 0.95c

Therefore the correct option is B.)

The population of a city is expected to increase by 7.5% next year If p represents the current population, which expression represents the expected population next year?

Let p = current population of a city.

Therefore the expression which represents the expected population next year is given by :

= p + $\dfrac{7.5}{100}$ p = 1.075p

Therefore the correct option is B.)

Kim picked 250 pounds of pears yesterday and 287 pounds of pears today. What is the percentage increase of

xxMikexx [17]

Given:

Kim picked 250 pounds of pears yesterday and 287 pounds of pears today.

To find:

The percentage increase of amount of pears picked by Kim.

Solution:

We know that,

$\%\text{ increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100$

$\%\text{ increase}=\dfrac{287-250}{250}\times 100$

$\%\text{ increase}=\dfrac{37}{25}\times 10$

$\%\text{ increase}=\dfrac{370}{25}$

$\%\text{ increase}=14.8$

Therefore, the percentage increase of amount of pears picked by Kim is 14.8%.
