The marked price of a water cooler is $ 4500. The shopkeeper offers an off-season discount of 18% on it. Find its selling price.

Answers

Answer:

$3690

Step-by-step explanation:

Let's first find what percent of the original price it is being sold for.

100%-18%=82%

The water cooler is being sold for 82% of its original price.

Let's now find 82% of 4500.

0.82*4500=3690

The selling price is $3690

Answer:

3690

Step-by-step explanation:

the original price is 4500

for decreasing or discount we use this formula x discount upo 100 multiply by the original price. so for this question if we apply the formula it will be

18upon 100 x4500. the answer comes as 810. noww we subtract the original price from the discounted price. so 4500-810=3690. comes as ur selling price

Answer these questions about finding the missing angle measures. What is the measure of ∠Q? What is the measure of ∠T? What can be concluded about these triangles?

Answers

Answer:

<Q = 44.4

<T = 44.4

The triangles are similar

Step-by-step explanation:

Both triangle QSR and triangle TUV are similar triangles since the corresponding angles are equal.

Similar figures

Two figures are similar if they have the same shape and the ratio of their corresponding sides are in the same proportion. Hence all the corresponding angles are similar.

From the diagram:

∠Q + ∠R + ∠S = 180° (angle in a triangle)

∠Q + 98 + 37.6 = 180

∠Q = 44.4°

∠T + ∠U + ∠V = 180° (angle in a triangle)

∠T + 98 + 37.6 = 180

∠T = 44.4°

Both triangle QSR and triangle TUV are similar triangles since the corresponding angles are equal.

Which statement is true?

Answers

Answer:

all parallelograms are rectangles

Step-by-step explanation:

the have 2 sets of parallel lines that are equal in length

The lines shown below are parallel. If the green line has a slope of 5, what is
the slope of the red line?

Answers

Answer:

D

Step-by-step explanation:

By definition, any two lines that are parallel must have the same slope, since they are angled the same amount (they travel the same amount up over a certain sideways distance). Hope this helps!

The required slope of the red line is equal to 5. Option D is correct.

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The slope of the parallel line is always equal, so as of the given condition if green and red lines are parallel then the slope of the red line is equal to the slope of the green line.
The slope of the red line = slope of the green line
The slope of red line = 5

Thus, the required slope of the red line is equal to 5, Option D is correct.
