A shopkeeper marks the price of an article
30% above its cost price and gives a customer discount of
15%. A customer bought that article including 13% VAT at
Rs. 1872.975. Find the marked price of the article and the
gain of shopkeeper

Answers

Answer:

The gain percent made by shopkeeper is 10.5%.

Step-by-step explanation:

Given:

Price at which goods are marked = 30%

Discount on the marked price = 15%

To Find:

Gain percentage of the shopkeeper

Solution:

Let the cost price of the product be = 100

Therefore,

MP = 30 + 100 = 130

Since discount is 15%. thus -

Discount = 15/100 x 130

= 19.5

Selling price = MP - Discount

SP = 130 - 19.5

= 110.5

Profit = SP - CP

= 110.5 - 100

= 10.5

Calculating the gain%

Gain% = 10.5/100 x 100

= 10.5

Answer: The gain percent made by shopkeeper is 10.5%.

Write an equation for the trend line shown. Type answer in y = mx + b format.

Answers

Answer:

y=1/4x+250

Step-by-step explanation:

Answer:

y = 12.5x + 250

Step-by-step explanation:

(4,300) , (8,350)

m = 350 - 300 / 8 - 4 = 25/2 = 12.5

y - 300 = 12.5(x - 4)

y - 300 = 12.5x - 50

y = 12.5x + 250

Solve for x. Round to the nearest tenth. 2.

Answers

Answer:

Step-by-step explanation:

Reference angle = 39°

Opposite = 27

Adjacent = x

Apply TOA. Thus:

Tan 39 = Opp/Adj

Tan 39 = 27/x

x * Tan 39 = 27

x = 27/Tan 39

x = 33.3422232 ≈ 33.3 (nearest tenth)

Why did the 30-60-90 triangle marry the 45-45-90 triangle

Answers

The cause due to which the triangles 30-60-90 married the triangle 45-45-90 would be:

They were right for each other.

Sum Property of Triangle

The sum of property of triangle states that the three angles of triangle give the sum of 180°.

Given that,

Two sets of triangles having the measures:

First set = 30°-60°-90°

Second set = 45°-45°-90°

The first set marries the other as they both are right i.e. 90° to one another and give an equal sum of 180°.

Thus, the above answer is correct.

Which expression has a lesser value than -10? a. 8+ (-12)
b. – 14 – 2 + 8
c. 4-(-12)
d. - 2 +(- 12) + 2
please show work!

Answers

Answer:

Step-by-step explanation:

Which expression has a lesser value than -10?

a. 8+ (-12)= -4

b. – 14 – 2 + 8= -16+8= -8

c. 4-(-12)= 16

d. - 2 +(- 12) + 2 = -12

Answer:

Step-by-step explanation:

8 +(-12) = 8-12 = -4

-4 > -10

14-2+8 = 12+8 = 20

20 > -10

4-(-12) = 4+12 = 16

16 > -10

-2+(-12)+2 = -2-12+2 = -14+2 = -12

-12 < -10

Jordyn is weighing the ingredients on a kitchen scale to make bread. The bowl weighs 1 12 pounds. He adds several scoops of flour. the total weight of the bowl and the flour is 2 34 pounds. If each cup weighs 516 pound, how many cups of flour does he add?

Answers

Answer:

4 POUNDS OF FLOUR

Step-by-step explanation:

The number of cups of flour he added is 4.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Bowl weight = 1(1/2) pounds

Number of cups of flour weight = x pounds

Now,

Total weight = 2(3/4) pounds

1(1/2) + x = 2(3/4)

x = 11/4 - 3/2

x = (11 - 6)/4

x = 5/4

Now,

Weight of each cup of flour = 5/16 pounds

Now,

The number of cups of flour.

= 5/4 ÷ 5/16

= (5 x 16) / (4 x 5)

= 4

Thus,

The number of cups of flour is 4.

[tex]\Huge\boxed{240ft^2}[/tex]

Step-by-step explanation:

Hello There!

The figure shown is a trapezoid with the following dimensions

base 1 = 12ft

base 2 = 20 ft

height = 15 ft

Given these dimensions we need to find the area

We can do this by using the area of a trapezoid formula

[tex]A=\frac{a+b}{2} h[/tex]

where a and b = bases and h = height

Knowing the dimensions all we have to do is plug in the values

[tex]A=\frac{12+20}{2} 15\\12+20=32\\\frac{32}{2} =16\\16*15=240\\A=240ft^2[/tex]

So we can conclude that the area of the floor that needs to be replaced with tile is 240 ft²

ANSWER:
240ft squared

STEP BY STEP:
1) find the area of the square (15x12)
2) find area of triangle (8x15)/2
Add these numbers up (180+60)

Hope this helps
