Answer: $22
Step-by-step explanation:
The wall is 23 ft by 8 ft, so if you multiply both sides of the rectangle together, you get the area.
23 * 8 = 184 ft^2
Since the wall requires 2 coats of paint, that means you'll just need to double the area you need to cover (since you're covering it twice).
184 * 2 = 368 ft^2
Now that we know how much square feet of area we need to cover, we can try and figure out how many gallons of paint we need to cover said area.
One gallon of paint covers 320 ft^2, so we can divide the area we need to cover (368) by the area a single gallon can cover (320) to get the amount of gallons we need to cover the wall.
368 / 320 = 1.15 gallons
To cover the wall twice, we need 1.15 gallons of paint. Assuming we can't buy 0.15 of a gallon, we will just need to buy two full gallons. Each gallon is $11, so two gallons each costing $11 is:
2 * 11 = $22
Side note: IF you can buy 0.15 of a gallon, then just multiply 1.15 * 11 = $12.65
Which expression is NOT equivalent to 6 × 14?
Answer:
D
Step-by-step explanation:

Therefore they are not equal.
Amelia collected 54 pieces of candy during Halloween. Of those 54 pieces, five-ninths had chocolate in them. Two-thirds of the ones that didn't have chocolate were gum. How many pieces of the 54 were gum? Show how you found your answer.
plz help me
[tex]\frac{5}{9}[/tex] of 54 are the ones which have chocolate , so we need to multiply the fraction by 54
[tex]\frac{5}{9} *54 =30[/tex]
Since 30 pieces of candy have chocolate, then 24 don't have it. [tex]\frac{2}{3}[/tex] of the last number are the ones which have gum, multiply [tex]\frac{2}{3}[/tex] by 24 to get the answer:
[tex]\frac{2}{3} *24=16[/tex]
The answer is : 16 pieces of candy have gum
PLEASE MARK ME AS BRAINLIEST
The number of pieces of gums are 16.
What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Given that, Amelia collected 54 pieces of candy during Halloween.
Of those 54 pieces, five-ninths had chocolate in them.
Number of chocolates = 5/9 ×54
= 30
Remaining candies =54-30
= 24
Two-thirds of the ones that didn't have chocolate were gum.
Now, 2/3 ×24
= 16
Therefore, the number of pieces of gums are 16.

best answer=brainiest can someone please explain algebraic expressions?
Answer: In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number). For example, 3x2 − 2xy + c is an algebraic expression.
Step-by-step explanation:
Answer:
An algebraic expression includes variables. Variables are letters that stand for a potential number; most commonly you see x, y, and z used but you can use any letter. Constants are also common in algebraic expressions, and are numbers that are added or subtracted, as well as coefficients, which are what you multiply the variable by.
For example:
3x + 1
Here, the variable is x. The constant is 1. The coefficient is 3.
These are different then other expressions because of the addition of variables. 4 + 4 is not an algebraic expression, but 4x + 4 is.
Algebraic expressions also do not have equal signs, they are not equations.
They can also be more complicated than the ones I've expressed already. 3x^4 + 2x^2 + 4 is an algebraic expression too.

What is the gravitational PE of the same 61.2 kg person standing on the 6th floor (Each story is 2.5 m high)?
Answer: U is the change in PE, m is the mass raised through a distance h. So, given m = 61.2 kg, each 1 m rise is an increase of (61.2)(9.8) = 600 J. Likewise, each floor (2.5 m) represents a change in PE of 1500 J for this mass.

Complete question :
Lilian purchased a violin form smash music stores. It regularly sold for $670, but wa son slaw for 10% off. She also had to pay 8% sales tax. She bought it on the installment plan and paid 15% of the total cost with tax as a down payment. Her payments were $58 per month for one year. What is her sales tax?
Answer:
$48.24
Step-by-step explanation:
Given that:
Sales price = 670
Discount = 10% off
Sales tax = 8%
Discounted price = (1 - 0.1) * 670
Discounted price = 0.9 * 670 = $603
Hence, purchase price = $603
Hence, sales tax = 8% of purchase price
8% of $603
0.08 * 603 = $48.24
If a bus driver leaves her first stop by 7:00 a.M., her route will take less than 35 minutes. If she leaves after 7:00 a.M., she estimates that the same route will take no less than 43 minutes. Write an inequality which represents the time it takes to drive the route, r.
Answer:
r < 35 or r ≥ 43
Step-by-step explanation:
We are told that when the bus driver leaves her first stop by 7:00 a.m., her route will take less than 35 minutes.
Since the time it takes to drive the route is r, then;
r < 35
Also, If she leaves after 7:00 a.M., she estimates that the same route will take no less than 43 minutes. Thus;
r ≥ 43
Thus;
r < 35 or r ≥ 43

If there are 360 g of radioactive material with a half life (decreased by half or 50% )of 1 hour, how much of the radioactive material will be left after 4 hours ?
After 1 hour, 360 g decays to 180 g.
After another hour (total 2 hours), 180 g decays to 90 g.
After another hour (total 3), 90 g decays to 45 g.
After one more (total 4), 45 g decays to 22.5 g.
More quickly, with a half-life of 1 hour, the 360 g of starting material decays to
(360 g) / 2⁴ = 22.5 g
In general, if the half-life is 1 hour, then after n hours, an initial amount A of this substance decays according to
A / 2ⁿ

Four friends bought an extra-large $12 popcorn. Each person bought their own drink. The total cost of the food can be represented by the expression 4x + $12.
Answer:
True
Step-by-step explanation:
This equation correctly represents the total cost of the food that the friends ended up paying for the popcorn and sodas. In this expression, the cost of each individual soda is represented by the variable x which is multiplied by 4 since each one of the four friend's purchased their own soda. After making this multiplication process that product is added to the initial $12 that they all spent together on the popcorn.
Each friend paid $4 for popcorn.
The total cost of the food can be represented by the expression 4x + $12.
Given
Four friends bought an extra-large $12 popcorn.
Each person bought their own drink.
Let x be the number of friends.
The total cost of food= Total number of friends + cost of popcorn.
The total cost of the food can be represented by the expression 4x + $12.
Therefore;
The amount paid by each friend is;
[tex]\rm 4x=12\\\\x=\dfrac{12}{3}\\\\x=4[/tex]
Hence, each friend paid $4 for popcorn.

O A. (x-2)(x-6)
B. (x + 2)(x-6)
c. (x - 2)(x+6)
D. (x-3)(x - 4)
Answer:
(x-2)(x-6)
Step-by-step explanation:
We look for two integers which multiply to +12 but add to -8 and we find those numbers by looking at the factors of 12={1,2,3,4,6,12}
We find that by picking 6 and 2,6×2=12 but 6+2 is not -8 so we tweak that as -6 and-2
By so doing, now -6×-2=12,-6+(-2)=-8
so we factor to get (x-2)(x-6)
