Profit = 8%

If the briefcase was marked down 20% from 1500 you multiply 1500 x .2 = 300 in order to calculate the discount.

Calculate the discounted price:

1500 - 300 = 1200

Calculate 10% discount of 1200:

1200 x .1 = 120

Calculate the sales price:

1200 - 120 = 1080

The last step is to calculate the profit/loss is the cost is 1000.

The briefcase sold for 1080 and the company paid 1000 for it, so there was a profit of 80.

The percentage is calculate by dividing 80/1000 = 8% profit

Twenty percent of the shoes in a factory are black. one shoe is chosen and replaced. a second shoe is chosen and replaced. then
viva [34]

The probability that none of the shoes are black is:

The probability of the shoe that black is: 0.2

The probability of the shoe that is not black is: 0.8

Black: 0.2

Not black: 0.8

Since we’re looking for the probability of the shoe that is not black and there are 3 in a row, the answer will be = 0.8^3

= 0.8^3 will give you the equivalent of 0.512

If changed in percent form, the answer will be: 51.2%

In triangle VWX, VW = 4.5 inches, WX = 5.9 inches, Measure of angle W = 28 degrees, and Measure of angle X = 47 degrees. If Tria
lesya692 [45]

Answer:

<u>There are two statements that are true:</u>

<u>B. QR = 5.9 cm </u>

<u>D. Measure of angle R = 47 degrees</u>

Step-by-step explanation:

1. Let's recall that if ΔVWX ≅ ΔPQR, then:

VW ≅ PQ

WX ≅ QR

PR ≅ VX

<u>therefore, QR is 5.9 cm and not 4.5 cm</u>

2. Let's recall that if ΔVWX ≅ ΔPQR, then:

∠V ≅ ∠P

∠W ≅ ∠Q

∠X ≅ ∠R

<u>therefore, measure of ∠R is 47° and not 28°</u>

<u>There are two statements that are true:</u>

<u>B. QR = 5.9 cm </u>

<u>D. Measure of angle R = 47 degrees</u>

In circle E with m \angle DEF= 70m∠DEF=70 and DE=13DE=13 units find area of sector DEF. Round to the nearest hundredth.
Anuta_ua [19.1K]

Answer:

103.18units³

Step-by-step explanation:

Area of the sector DEF = theta/360 * πr²

r is the radius

theta is the angle subtended at the centre

theta =70 degrees

radius DE = 13units

Substitute

Area of the sector = 70/360 * 3.14(13)²

Area of the sector = 7/36 * 530.66

Area of the sector = 3,714.62/36

Area of the sector = 103.18units³ (to the nearest hundredth)
