A painter is painting a rectangular wall that measures 23.6 ft by 19.2 ft. Each gallon can of paint covers 200 square feet. What are the fewest gallons needed to paint the wall?

Answers

Answer 1

Answer:

3 gallons

Step-by-step explanation:

Length of the rectangular wall = 23.6 feet

Width of the rectangular wall = 19.2 feet

Surface area of the wall = 23.6 × 19.2

                                        = 453.12 square feet

∵ 200 square feet of the wall is covered by the amount of paint = 1 gallon

∴ 1 square feet of the wall will be covered by the amount of paint = [tex]\frac{1}{200}[/tex] gallons

∴ 453.12 square feet will require the amount of paint = [tex]\frac{453.12}{200}[/tex]

                                                                                         = 2.2656 gallons

Therefore, minimum 3 gallons will be required to paint the wall.

6/7 times 3/4 = x
IN SIMPLEST FORM

Answers

Answer:

I believe 6/7 times 3/4 in the simplest form is 9/14 because you aren't able to put anything in both of those numbers

Step-by-step explanation:

The value of x in the equation (6/7) × (3/4) = x is 9/14.

To find the value of x in the equation (6/7) × (3/4) = x.

We can simply multiply the two fractions together.

Multiplying the numerators and denominators gives us:

(6 × 3) / (7 × 4)

= 18/28

The fraction 18/28 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2.

(18/2) / (28/2)

= 9/14

A TV that usually sells for $185.63 is on sale for 25% off. If sales tax on the TV is 5%, what is the price of the TV, including tax?

Answers

Answer: A TV that usually sells for $185.63 is on sale for 25% off. If sales tax on the TV is 5%, what is the price of the TV, including tax?

178.18 x 0.25 = 44.55

178.18 - 44.55 = 133.63 = sales price

133.63 x 0.05 = 6.68

133.63 + 6.68 = 140.31 = total price

Step 1: Simplify both sides of the equation.

27+9x=12x−6

27+9x=12x+−6

9x+27=12x−6

Step 2: Subtract 12x from both sides.

9x+27−12x=12x−6−12x

−3x+27=−6

Step 3: Subtract 27 from both sides.

−3x+27−27=−6−27

−3x=−33

Step 4: Divide both sides by -3.

Be sure to use proper grammar, spelling, and mechanics."School Uniforms"Requiring uniforms in public high schools has been debated for many years. There are certainly many positive reasons for having students wear them. If students were uniformly dressed, there would be less distractions about clothing, adding more focus on academics. Another reason to add uniforms is that there would no longer be conflict over how young people dress. There would be no singling out of poorer students who cannot wear designer labels, and young people wouldn't have to worry so much about fitting in because of how they dress. Opponents, however, say requiring school uniforms suppresses a young person's need for individuality. This simply isn't the case, though, as students can use hairstyle, jewelry, and so on to show their individuality. Requiring school uniforms would erase a number of conflicts and problems facing high school students today.

Such, at least, is the verdict of many whose fortune it has been to traverse that favored stretch of country. Nothing butthe limited power of man's eyes prevents him from standing on the top of the mountains and surveying, at a glance, the whole gloriouspanorama that stretches away for more than two hundred miles to the west, terminating in the gleaming waters of the Pacific Ocean. Could hedo this, he would behold, for the first seventy-five or eighty miles, a vast, billowy sea of foot-hills, clothed with forests of somber pine and bright,evergreen oaks; and, lower down, dense patches of white-blossomed chaparral, looking in the enchanted distance like irregular banks of snow.Then the world-renowned valley of the Sacramento River, with its level plains of dark, rich soll, its matchless fields of ripening grain, traversedhere and there by streams that, emerging from the shadowy depths of the foot-hills, wind their way, like gleaming threads of silver, across thefertile plain and join the Sacramento, which receives them, one and all, in her matronly bosom and hurries with them on to the sea.
