I guessed and check since it is a small number and found that 7+14+21 adds up 42 matching your ratio.
Vilka [71]1 year ago

the ratio in which 42 should be divided is 1:2:3

the sum of the parts of the ratio is - 1 + 2 + 3 = 6

this means that there's a sum of 6 parts

so we need to find how much 1 part is equivalent to

if 6 parts are equivalent to 42

then 1 part is equivalent to - 42/6 = 7

so the ratio should be 1:2:3

1 part - 7

2 parts - 7 x 2 = 14

3 parts - 7 x 3 = 21

therefore 42 divided into 1:2:3 ratio is as follows

7 : 14 : 12

NeX [460]

Answer:

Sales of 35 leather wallets will give profit of $192.5

Step-by-step explanation:

If sales of 20 leather wallet gives $110

Sales of 35 leather wallet gives x

Cross multiply

20x = 110 x 35

20x = 3850

Divide both sides by 20

x = 3850/20

x = $192.5

HELP PLS>>> The vector (3, - 7) ) is rotated by an angle of (3pi)/4 radians and then reflected across the y-axis. If th
horsena [70]

Answer:

a \approx -2.826, b \approx 7.072

Step-by-step explanation:

First, the vector must be transformed into its polar form:

r = \sqrt{3^{2}+ (-7)^{2}}

r \approx 7.616

\theta \approx 2\pi - \tan^{-1}\left(\frac{7}{3} \right)

\theta \approx 1.629\pi

Let assume that vector is rotated counterclockwise. The new angle is:

\theta' = \theta + \frac{3\pi}{4}

\theta' = 2.379\pi

Which is coterminal with \theta'' = 0.379\pi. The reflection across y-axis is:

\theta''' = \pi - \theta''

\theta''' = 0.621\pi

The equivalent vector in rectangular coordinates is:

a = 7.616\cdot \cos 0.621\pi

a \approx -2.826

b = 7.616\cdot \sin 0.621\pi

b \approx 7.072

A stadium brings in $16.25 million per year. it pays football-related expenses of $13.5 million and stadium expenses of $2.7 mil
Ganezh [65]
We have that

Profit margin is calculated by finding the net profit as a percentage of the revenue

Profit margin = [Net profit / Revenue]

Net profit= [Revenue-Cost]

we know that

Revenue = $16.25 million

Cost = $13.5 million + $2.7 million

Net profit = [16.25 million - (13.5 million + 2.7 million)]

Net profit = $0.05 million

Profit margin = 0.05 / 16.25

Profit margin = 0.003077 or 0.3077%

A bowl contains 25 balls numbered 1 to 25. A ball is drawn and its number is noted. Without replacing the first ball, another ba
Afina-wow [57]

Step-by-step explanation:

n(S) = 25

Assume that O : odd numbers and E : even numbers,

n(O) = 13

n(E) = 25-13 = 12

P(OO) = P(O) x P(O)

= 13/25 x 12/24

(because without replacing so the number of balls left decreases)

= 13/25 x 1/2

= 13/50
