A gallon of paint can cover 150 square feet. Find how many galloti container of paint should be beate to paint 3 coats on each wall of a rectangular room with dimension feet by 14 feet and will shar 12-feet tall.

Answers

Answer 1

Answer:

Area of the wall = 12 ft * 14 ft = 168 ft^2

Each wall is coated thrice with the paint.

Therefore, 168ft^2 * 3 = 504 ft^2

150ft^ 2 = 1 gallon paint.

Therefore 504 ft^2 requires

= 504/150

= 3.36 gallons of paint

What is the slope of a line that is perpendicular to the line y=1/6x+4?

Answers

The slope would be -6 because it is the opposite reciprocal. Not just the reciprocal.

Slope of a line that is perpendicular to the given line is -6.

What is slope?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Given equation

$y=(1)/(6)x+4$

It is in the form of $y=mx+b$

Comparing two equations

Slope :

$m =(1)/(6)$

Slope of a line that is perpendicular to the line:

= $-(1)/(m)$

= $-(1)/((1)/(6) )$

= -6

Slope of a line that is perpendicular to the given line is -6.

Suppose y varies directly with x, and y =24 when x=8. what is the value of y when x=10?

Answers

The value of y when x is equal to 10 is 30. This is because for every value of x the value of y is 3. This can be known if you divide 24 by 8 you get 3. So if x=10 then y would equal 30.

A toy manufacturer produces the same toy in 4 different colors: red, blue, green, and yellow. The toy manufacturer has 5 production lines dedicated to the red version, 5 production lines dedicated to the blue version, 4 production lines dedicated to the green version, and 2 production lines dedicated to the yellow version. A toy has an equal chance of traveling down any production line. What is the probability that the toy will not be green?

Answers

Answer:

The probability that the toy will not be green is 3/4 or 0.75

Step-by-step explanation:

Consider the provided information.

A toy manufacturer produces the same toy in 4 different colors: red, blue, green, and yellow.

Production lines dedicated to the red = 5

Production lines dedicated to the blue = 5

Production lines dedicated to the green = 4

Production lines dedicated to the red = 2

We need to calculate the probability that that the toy will not be green.

The total number of toys are: 5 + 5 + 4 + 2 = 16 toys.

Total toys that are not green = 5 + 5 + 2 = 12 toys.

$Probability=\frac{\text{Favorable outcomes}}{\text{Total number of outcomes}}$

Substitute the respective values in the above formula.

$Probability=(12)/(16)$

$Probability=(3)/(4)=0.75$

Hence, the probability that the toy will not be green is 3/4 or 0.75

5 + 5 + 4 + 2 = 16

16 - 4 = 12

12/16 = 3/4

The probability that the toy will not be green is 3/4.

A frying pan has a radius of 14 centimeters. What is the circumference of the frying pan

Answers

The formula for the circumference of a circle is:

C=2πr

Since we know the radius is 14cm, we can solve for the circumference...
C=2π(14)
C=28πcm
C=87.96cm

The curcumfrence is 87.92 centimeters. I multiplied 14 by 2 because you multiply the diameter by 3.14. Diameter is radius times 2. Then you would multiply 28 by 3.14 because C = d times 3.14. d is diameter and C is circumference. Hope this helps
