) The price of a watch is marked Rs 11,250. When it is sold allowing 20% discount,
20% profit is made. By what percent is the discount to be reduced to increase the
profit by 3%?​

Answers

Step-by-step explanation:

the first step is to find the cost price

when 20% discount=

11250*80/100= 9000

the 20% discounted price is 9000

there is still a 20% profit in this 20% discount

so Cost.Price *120/100=9000

Cost price= 7500

now its asking for discount percentage at 3% profit so first calculate price after 3% profit

7500*103/100= 7725

so discount on rs11250 required to produce 3% profit=

11250*x/100=7725

x= 68.7% discount

Given: AC = AB, CD = DE

m∠ABC = 70°, m∠ ECB = 35°


Prove: DE ║BC



m∠ACB = m∠______, By reason ( Base angles theorem, Exterior Angle theorem, Supplementary angles, Vertical Angles theorem ) - choose one

Answers

Answer:

a)[tex]\angle ACB = \angle ABC[/tex] By Base angle theorem

b)DE||BC since[tex]\angle DEC=\angle ECB[/tex] and they are alternate interior angles

Step-by-step explanation:

Given: AC = AB, CD = DE

∠ABC = 70°, m∠ ECB = 35°

Refer the attached figure

AB = AC

So, By Base angle theorem : if the sides of a triangle are congruent then the angles opposite these sides are congruent.

So, [tex]\angle ACB = \angle ABC[/tex]

So,[tex]\angle ACB = \angle ABC =70^{\circ[/tex]      ----1

CD = DE

So, by Base theorem

[tex]\angle DCE = \angle DEC[/tex]

Let [tex]\angle DCE[/tex]  be x

So,[tex]\angle DCE = \angle DEC[/tex]

[tex]\angle ACB= \angle DCE+\angle ECB = x+35[/tex]

Using 1

70 = x+35

35=x

[tex]\angle DCE = \angle DEC =35^{\circ}[/tex]

Now[tex]\angle DEC=\angle ECB=35^{\circ}[/tex]

So, DE||BC since[tex]\angle DEC=\angle ECB[/tex] and they are alternate interior angles

The function y=0.75x + 2 represents the cost y (in dollars) of an ice cream sundae with x toppings. A sundae comes with 1, 2, 3, or 4 toppings. Identify the independent and dependent variables, the domain, and the range.​

Answers

Answer:

Please check answer for explanation

Step-by-step explanation:

The independent variable is x

The dependent variable is y

The domain is the range of values of x

That will be 1-4

Now let’s get the range, the range just represent the y-values of the terms in the domain

at x = 1

y = 0.75(1) + 2 = 2.75

at x = 4

y = 0.75(4) + 2 = 3 + 2 = 5

The range is 2.75 to 5

Find the greatest common factor of 35 and 26

Answers

Answer:

1

Step-by-step explanation:

The factors of 26 are:

1, 2, 13, 26

The factors of 35 are:

1, 5, 7, 35

The common factors are:

1

The required greatest common factor(GCF) of 35 and 26 is 1.

What is the Greatest Common Factor (GCF)?

The greatest Common Factor is defined as the greatest number that is a factor of both numbers when two numbers are involved.

A number that divides into another number completely is said to be a factor.

The numbers are given in the question, as follows:

35 and 26

We have to determine the greatest common factor of 35 and 26

Prime factorization of the numbers:

35 = 5 × 7

26 = 2 × 13

GCF(35, 26)

= 1

Hence, the required greatest common factor of 35 and 26 is 1.

B 2x - 6 = 18
С
4x = 24
D
X-4 = 24
E 8x - 24 = 72

Answers

Hi :)

A) 4x = 48: x= 12
B) 2x -6 = 18 x=12


4x - 12 = 36

Add 12 to both sides
4x=36+12

Add 36 and 12 to get 48
4x=48

Divide both sides by 4
x= 4/48


Divide 48 by 4 to get 12
x=12

Answers

I’m pretty sure it’d would be the first car because when dividing the miles by the hours they travelled you get how many miles they drove per hour so try the first car.

61mph first car, second car 59mph, third car 58mph and fourth car 57mph.

In the garden, there were 15 red flowers, 5 blue flowers and 2 yellow flowers. What percent of the flowers were red?​

Answers

Answer:

68.2

Hope this helps. :)

Answer:

I believe it would be 65?

Step-by-step explanation:

if if I divide 22 by 100 I will get 2.2.

And at 5 + 2 that means if you combine the blue flowers and yellow flowers you will get $7 in total.

And there's 15 red flowers 7 is kind 40 of 15 which is 100 because. 8+7=15 .

And for 15 to be completely split in half it would have to be 7.5.

But that's not how it works so if we put 8 & 7 into percents 8 would be 65 and 7 would be 35
