7. A shopkeeper buys 300 identical articles a tota

sashaice [31]

Step-by-step explanation and answers:

300 articles at a total cost of $1500:

$1500 / 300 = $5 / article

Sells 260 articles at a price 20% above this ^ price:

20% of $5 is $1, so $5 + $1 = $6

Then he sells 260 articles at the price of ^ $6

260 * $6 = $1560

Each of the remaining articles is sold at a price that's 50% of the 260 he sold.

He sold those for $6, so he would now sell the last 40 for $3

From the remaining 40 articles, he makes 40 * $3, or $120

The shopkeeper made $1560 + $120 = $1680, which is $180 more than he bought them for ($1500)

Therefore, he made a profit percentage of $180 / $1500, (the amount of profit over the amount spent).

He made a profit percentage, compared to the cost price, of 12%.

In triangle ABC, AD is a median. FE is a straight line parallel to BC cutting the remaining sides AB at F and AC at E and cuttin

daser333 [38]

Answer:

Step-by-step explanation:

since AD is a median it implies that triangle ABC is bisected to two equal right angled triangle which are ADB and ADC.

FE is parrallel to BC and cuts AB at F and AC at E shows that there are two similar triangles formed which are AFE and ABC.

Recall that ADC is a right angled triangle, ED bisects a right angled triangle the the ADE = $45^{o}$ .

Now, Let FD bisect angle ADB,

then ADF = $45^{o}$ too.

Since AFX is similar to Triangle ABD and that Triangle AEX is similar to Triangle ACD, then EDX is similar to FDX

FDE = ADF + ADE = $90^{o}$

I need help pls is only 1 question

Yanka [14]

Answer:

$T = 1300$

Step-by-step explanation:

Given

$Radius, r = 9\ in$

$Height, h = 14\ in$

See attachment

Required

Determine the total surface area, T

T is calculated using:

$T = 2\pi r(r + h)$

Substitute values for r and h

$T = 2\pi * 9(9 + 14)$

$T = 2\pi * 9(23)$

Remove bracket

$T = 2\pi * 9*23$

$T = 2\pi * 207$

Take $\pi = 3.14$

So, we have:

$T = 2 * 3.14 * 207$

$T = 1299.96$

$T = 1300$ --- approximated.

Hence, the surface area is 1300 square inch
