Write an equation of the line that passes through (7,10) and is perpendicular to the line y=12x−9.
Ulleksa [173]

Answer:

<em>y = - </em>\frac{1}{12}<em> x + </em>\frac{127}{12}<em> </em>

Step-by-step explanation:

y = 12x - 9

Slope of line perpendicular to given is m = - \frac{1}{12}

P(7, 10)

y - 10 = - \frac{1}{12} (x - 7)

<em>y = - </em>\frac{1}{12}<em> x + </em>\frac{127}{12}<em> </em>

How do we figure this out
lisov135 [29]

Answer:

Pair 1: 10 cm and 2 cm. and the sum is 12 cm.

Pair 2: 20 cm and 4 cm. and the sum is 24 cm.

Step-by-step explanation:

Area of a rectangle is given by A = LW, where L is the length and W is the width of the rectangle.

Pair 1:

For the first rectangle W = 4 cm and A = 40 sq, cm

Then L = \frac{A}{W} = \frac{40}{4} = 10 cm.

For the second rectangle W = 4 cm and A = 8 sq, cm

Then L = \frac{A}{W} = \frac{8}{4} = 2 cm.

Therefore, the sum of two unknown lengths = 10 + 2 = 12 cm. (Answer)

Pair 2:

For the first rectangle W = 4 cm and A = 80 sq, cm

Then L = \frac{A}{W} = \frac{80}{4} = 20 cm.

For the second rectangle W = 4 cm and A = 16 sq, cm

Then L = \frac{A}{W} = \frac{16}{4} = 4 cm.

Therefore, the sum of two unknown lengths = 20 + 4 = 24 cm. (Answer)

You are at a campus party where there are a total number of n people. The host asked everyone to put their phones in a bowl whil
kirill [66]

Answer:

1, \frac{m}{n}, \frac{1-m}{n}.

Step-by-step explanation:

probability = \frac{Number of Possible Outcomes}{Total Outcomes}

Total number of persons in the party = n

a) Pr ( every person gets their phone back) = Pr (each person picks his phone ) multiplied by number of person

   = \frac{1}{n} × n = 1.

     No of first m persons to pick = m

     No of last m persons to pick = 1 - m

b) Pr (first m persons to pick each gets their phones back) = \frac{m}{n}

c) Pr( first m persons get a phone belonging to last m persons) = \frac{1-m}{n}

Jackson purchased a pack of game cards that was on sale for 22% off. The sales tax in his county is 6%. Let y represent the orig
Ymorist [56]

Answer:

Final cost = 0.9328y

Step-by-step explanation:

Assume,

Original price = y

Given:

Discount = 22%

Sales tax = 6%

Computation:

Sales tax will be added on sale value

So,

Sales price = y[100%-22%]

Sales price = 0.88y

Price after sales tax :

Final cost = 0.88y[100% + 6%]

Final cost = 0.88y[106%]

Final cost = 0.9328y
