The shopkeeper offers an off-season discount of 18% on it. Find its selling price.
Answer:
3813
Step-by-step explanation:
M.P of water cooler=$4650
Discount% on water cooler=18%
Discount on water cooler=18/100*$4650 i.e.$837
So,selling price=$4650-$837i.e.$3813 Ans.
Answer:
3813
Step-by-step explanation:
the formula will be 18 upon 100 multiply by 4560. the answer is 837. now subtract the original price from the discount. 4560-837 is 3813 which is ur answer.

6. What is the slope of the line pictured?
Answer:
-1/3
Step-by-step explanation:
We can do this by counting the number of spaces away the points shown are. Starting from the leftmost point, you move down one, or -1, units, and right 3 units. Since slope is defined as rise over run, you can then say that the slope is:
-1/3

The distance on a map is 4.5 cm. The scale of the map is 1 : 1000. What is the actual distance?. Single choice.
Answer:
Actual distance is 4500 cm (45 m).
Step-by-step explanation:
A scale is a representative fraction that can be used to either increase or decrease proportionally the dimension of a given object.
scale = [tex]\frac{distance on map}{actual distance}[/tex]
It is in the form of a ratio.
From the question, Distance on map = 4.5 cm,
scale = 1 : 1000
= [tex]\frac{1}{1000}[/tex]
scale = [tex]\frac{distance on map}{actual distance}[/tex]
Let the actual distance be represented by d.
So that,
[tex]\frac{1}{1000}[/tex] = [tex]\frac{4.5}{d}[/tex]
⇒ d = 4.5 x 1000
= 4500
d = 4500
The actual distance is 4500 cm (45 m).

Answer:
r = 14
Step-by-step explanation:
9r - 66 = 116 - 4r
+4r +4r
13r - 66 = 116
+66 +66
13r = 182
divide both sides by 13
r = 14

(5x + 4)^2
The multiplication of the given equation i.e. [tex](5x + 4)^2[/tex] should be considered as the [tex]25x^2 + 40x + 16[/tex].
Calculation of the equation:Since the given equation is [tex](5x + 4)^2[/tex]
We have to break this equation
So, it can be like
[tex](5x)^2 + 2 \times 5x \times 4 + 4^2[/tex]
[tex]25x^2 + 40x + 16[/tex]
Hence, we can conclude that The multiplication of the given equation i.e. [tex](5x + 4)^2[/tex] should be considered as the [tex]25x^2 + 40x + 16[/tex].

The equation P = 21 + 2w can be used to find the perimeter of a rectangle. A 1 point rectangular shaped playground is enclosed by a fence that is 500 m. The length of the playground is 120 m. Use the equation to determine the width of the playground *
Answer:
130 mStep-by-step explanation:
Given:
P = 2l + 2wP = 500 mLength is:
l = 120 mSubstitute values and solve for w:
500 = 2*120 + 2w2w = 500 - 2402w = 260w = 260/2w = 130 m
