If the rate of markup on selling price is 40%, what is the rate of markup on cost.

1 answer:

4 0

If your customer sees a ticket price of $18.33 on the item and knows you paid $11.00 and marked it up $7.33, then he calculates $7.33 as 40% of $18.33. Thus your cost of $11.00 is 60% of $18.33.

Cuál es el menor número entero que, disminuido en 8, resulta menor que su triple

Mars2501 [29]

Answer:

-3

Step-by-step explanation:

Let x = the number

Then 3x = its triple, and the condition is:

x - 8 < 3x

Subtract x from each side

-8 < 2x

Divide each side by 2

-4 < x

Reverse the inequality

x > -4

The smallest integer greater than -4 is -3.

Check:

-3 - 8 < 3(-3)

-11 < -9

It checks.

Winne is currently considering two plans for paying for piano lessons.

SVEN [57.7K]

Answer:

Plan B

Step-by-step explanation:'

First u have to divide each one to see how much each piano lesson costs.

Plan A- 31.50/6=5.25

Plan B- 20.60/4=5.15

So since Plan B is less then Plan B would be the answer.

Answer:

In 6 different ways can the three students form a set of class officers.

Step-by-step explanation:

There are 3 people Leila, Larry, and Cindy and 3 positions president, vice-president, and secretary.

We need to find In how many different ways can the three students form a set of class officers.

This problem can be solved using Permutation.

nPr = n!/(n-r)! is the formula.

Here n = 3 and r =3

So, 3P3 = 3!/(3-3)!

3P3 = 3!/1

3P3 = 3*2*1/1

3P3 = 6

So, in 6 different ways can the three students form a set of class officers.

Help asap plssssssssss

Kryger [21]

Step-by-step explanation:

distance AB is (using Pythagoras with the coordinate differences between both points as sides and the distance as Hypotenuse = baseline of the triangle, the side opposite of the 90 degree angle):

distance² = (5 - -10)² + (7-2)² = 15² + 5² = 225 + 25 = 250

distance = sqrt(250)

to split this distance into a 3/2 ratio, we need actually 3+2=5 equal parts. and then AM gets 3 off these parts, and MB gets 2 of these parts.

so,

distance/5 = sqrt(250)/5 = sqrt(250/25) = sqrt(10)

so,

AM = 3×sqrt(10) = sqrt(90),

and

MB = 2×sqrt(10) = sqrt(40)

now, we need to calculate back using the same Pythagoras approach (calling the coordinates of M xm and ym)

AM² = (xm - -10)² + (ym - 2)² = (xm+10)² + (ym-2)² = 90

90 = xm² + 20xm + 100 + ym² - 4ym + 4

MB² = (5 - xm)² + (7 - ym)² = 40

40 = 25 - 10xm + xm² + 49 - 14ym + ym²

as a first approach we calculate AM² - MB²

90 = xm² + 20xm + ym² - 4ym + 104

- 40 = xm² - 10xm + ym² - 14ym + 74

----------------------------------------------------

50 = 0 + 30xm + 0 + 10ym + 30

20 = 30xm + 10ym

2 = 3xm + ym

ym = 2 - 3xm

this we use now e.g. in the first equation for AM.

90 = xm² + 20xm + (2-3xm)² - 4×(2-3xm) + 104

-14 = xm² + 20xm + 4 - 12xm + 9xm² - 8 + 12xm

-10 = 10xm² + 20xm

-1 = xm² + 2xm

xm² + 2xm + 1 = 0

solving such a squared equation

xm = (-b ± sqrt(b² - 4ac))/(2a)

a = 1

b = 2

c = 1

xm = (-2 ± sqrt(4 - 4))/2 = -1

only one combined solution (as a squared equation usually has 2 solutions).

ym = 2 - 3xm = 2 - 3×-1 = 2 + 3 = 5

so, M = (-1, 5)

What is the volume of this oblique cone? 12π cm³ 40π cm³ 60π cm³ 120π cm³ An oblique cone with radius of six centimeters and hei

Pepsi [2]

We have to find the volume of oblique cone. An oblique cone is a special type of cone in which the apex is not located directly above the center of the circular base, so it looks like a slanted cone.

Volume of oblique cone = $\frac{1}{3} \Pi r^{2}h$

where 'r' is the radius and 'h' is the height.

Here r = 6 cm and h = 10 cm

Volume = $\frac{1}{3} (\Pi (6)^{2} \times 10)$

= $\frac{360\Pi }{3}$

= $120\Pi cm^{3}$

So, the volume of the given oblique cone is $120\Pi cm^{3}$ .

Option 4 is the correct answer.
