Answer:

  • C. -7/3

Step-by-step explanation:

<u>The slope of the line that passes through points (0, 0) and (-7, -3) is:</u>

  • m = (y₂ - y₁)/(x₂ - x₁)
  • m = (-3 - 0)/(-7 - 0) = 3/7

<u>Perpendicular lines have opposite-reciprocal slopes:</u>

  • -1 / (3/7) = - 7/3

Correct choice is C

Answer: C. -7/3

Step-by-step explanation:

The slope of the line that passes through points (0, 0) and (-7, -3) is

m= (y₂ - y₁)/(x₂ - x₁)

m= (-3 - 0)/(-7 - 0) = 3/7

Perpendicular lines have opposite-reciprocal slopes:

-1 / (3/7) = - 7/3

Correct answer is C

On a recent trip to the convenience​ store, you picked up 3 gallons of​ milk, 6 bottles of​ water, and 8 ​snack-size bags of chi
SVETLANKA909090 [29]

Answer:

The answers to the question are as follows

A bottle of water costs  $2.00

A gallon of mik cots $4.10 and

A bag of chips costs $1.00

Step-by-step explanation:

To solve the question, it is important to note that it is a word problem hence we read the question carefully to clearly understnd and be able to interprete the message from any perspective

We list out the variables as follows

Number of gallons of milk = 3

Number of bottles of water = 6

Number of chips bags = 8

Bill before tax = $32.30

Price of a bottle of water = twice the price of a bag of chips

Price of a gallon of mlk  = $ 2.10 + price of a bottle of water

Therefore in order to find out how much each item costs let us call the price of  bottle of water $x say

This means that the price of a bag of chips = x/2 and

The price of a gallon of milk = x + $2.10

Therefore  we have by multiplying the prices of the items to their respective quantities and summing up

$(6x + 3(x+2.1)+ 8 x/2) = $32.3

This gives by expanding the values 6x+3x+6.3+4x =32.3

13x+6.3 =32.3

13x = 32.3 - 6.3 = 26

Dividing both sides by 13 gives

x = $2.00

This means that a bottle of water costs  $2.00

A gallon of mik cots $2.00+$2.10 = $4.10

A bag of chips costs x/2 which is equal to $2.00/2 = $1.00

A cylindrical grain bin has a radius of 7 feet and a height of 25 feet. How many cubic feet of grain can the bin hold
dimaraw [331]

Answer:

1225π

Step-by-step explanation:

The question concerns the volume of the cylinder.

The formula of the volume is:

V=\pi r^{2} h, where r is the radius and h is the height.

Plugging the given numbers into the formula, we find that:

V=\pi * 49 * 25=1225\pi

The result - 1225π shows that the cylinder can be filled fully with that given amount.

A pipe is 36 feet long. It needs to be cut into pieces that are each 3/4 feet long. How many pieces can be made from the pipe?

108/4 = 27 pieces you multiply 36 x 3 = 108 and the denominator stays the same so 108/4 equals to 27 pieces
