After taking out percentages we know that Riley has used more percentage of white paint which is 42.85% and her grey paint would be lighter.

A % is a quantity or ratio that, in mathematics, represents a portion of one hundred.

A dimensionless relationship between two numbers can be represented in a variety of ways, such as through ratios, fractions, and decimals.

The symbol "%" is frequently written after the number to indicate percentages.

So, the percentages would be:

Riley:

4 black and 3 white

Total = 7

Percentage of white paint:

3/7 * 100 = 42.85%

Christian:

7 black and 4 white

Total = 11

Percentage of white paint:

4/11 * 100 = 36.36%

Answer: A

Step-by-step explanation: 2/-3 means that the - sign should be brought up. So, A is correct.

a)  The demand (price) function in terms of x : P(x) = 12 - 0.025(x - 1500)

b) the marginal revenue function is [tex]MR(x) = dR(x)/dx = 12 - 0.05(x - 1500)[/tex] The marginal revenue from the sales of 1800 T-shirts is -$3. This means that for each additional T-shirt sold after the 1800th, the revenue will decrease by $3 per T-shirt

To determine the demand (price) function, we need to find a relationship between the price of the T-shirts (P) and the number of T-shirts sold (x). We are given that for every $0.50 decrease in price, 20 more T-shirts will be sold.

Let's first find the decrease in price per T-shirt sold. If 20 more T-shirts are sold for every $0.50 decrease, then the decrease per T-shirt is $0.50/20 = $0.025. Now, we can set up the demand function. The base price is $12, and we decrease it by $0.025 for each additional T-shirt sold. So the demand function is:

P(x) = 12 - 0.025(x - 1500) To determine the marginal revenue function, we first need to find the total revenue function. Total revenue (R) is the product of the price (P) and the number of T-shirts sold (x):

R(x) = P(x) * x = (12 - 0.025(x - 1500)) * x Now we need to find the derivative of the total revenue function with respect to x, which will give us the marginal revenue function: MR(x) = dR(x)/dx = 12 - 0.05(x - 1500)

To determine the marginal revenue from the sales of 1800 T-shirts, we simply plug in x = 1800 into the marginal revenue function: MR(1800) = 12 - 0.05(1800 - 1500) = 12 - 0.05(300) = 12 - 15 = -$3

If Kenneth has 5/8 feet of lumber, then he need 83/40 feet of lumber to make the shelf.

First we convert the length of lumber in improper fraction form,

So, we convert 2(7/10) feet to an improper fraction,

⇒ 2(7/10) = (2×10 + 7)/10 = 27/10,

To find the length of lumber required we need to subtract the amount of lumber Kenneth has from the total length required,

Kenneth has a total of 5/8 feet of lumber,

Length of lumber required is = 27/10 - 5/8,

Taking LCM of 10 and 8 as 40 , and simplifying further,

We get,

Answer: 3.31662479036.

At Bank A, the interest rate was 8% (7.94% rounded to the nearest fourth of a percent). At Bank B, the interest rate was 5% (5.09% rounded to one decimal place).

To find the interest rate at each bank, we can use the formula for compound interest and the formula for continuously compounded interest.
For Bank A, the formula for compound interest is A = P(1 + r/n)^(nt), where A is the final amount, P is the principal, r is the interest rate, n is the number of times the interest is compounded per year, and t is the number of years.
Plugging in the values we have, we get:
51010.5 = 1000(1 + r/4)^(4*5)
Solving for r, we get:
r = 4[(51010.5/1000)^(1/20) - 1]
r = 0.1999
So the interest rate at Bank A is about 19.99%, or 20% when rounded to the nearest fourth of a percent.
For Bank B, the formula for continuously compounded interest is A = Pe^(rt), where A is the final amount, P is the principal, r is the interest rate, and t is the number of years.
Plugging in the values we have, we get:
5192.20 = 5500e^(r*5)
Solving for r, we get:
r = (1/5)ln(5192.20/5500)
r = -0.0118
So the interest rate at Bank B is about -1.18%, or -1.2% when rounded to the nearest fourth of a percent.
Therefore, the interest rate at Bank A is about 20% and the interest rate at Bank B is about -1.2%.

The  (√12 - √3)² = 6 according to the provided assertion.

Why do you use the word "binomial"?

A Binomial is a name for an algebraic equation with only two elements. It is a polynomial with two terms. It is also referred to as the total or difference of two or more binomials. It is a polynomial's most basic shape.

To expand and simplify the expression (√12 - √3)², we can use the formula for the square of a binomial:

(a - b)² = a²  + b² - 2ab

In this case, a = √12 and b = √3, so we have:

(√12 - √3)² = (√12)² - 2(√12)(√3) + (√3)²

To simplifying, we have:

(√12 - √3)² = 12 - 2√36 + 3

Since √36 = 6, we can simplify further:

(√12 - √3)² = 12 - 2(6) + 3 = 6

Therefore, the expanded and simplified equation (√12 - √3)² = 6.

Two families attended a baseball game, where they bought popcorn and souvenir. popcorn cost $4 and cost of souvenir is $7.

An equation is an expression that shows the relationship between two or more variables and numbers. Through equations the given information can be denoted as,

Let x = price of 1 bag of popcorn

Let y = price of 1 souvenir cup

First family:

3x + 4y = 40 (equation 1)

Second family:

8x + 4y = 60 (equation 2)

We have a system of 2 equations with 2 variables.

3x + 4y = 40

8x + 4y = 60

We are asked for the price of 1 bag of popcorn, x, so we will eliminate y and solve for x.

Answer:

D

Step-by-step explanation:

We can see that the points of intersection occur at π/3 and 4π/3.

We will solve this equation on the interval [0,2π). To begin, we can break up the equation into two parts:

2cosθ - 1 = 0 and 5cotθ + 4 = 0

First, let's solve the equation 2cosθ - 1 = 0. We can solve this equation by adding 1 to both sides and then dividing both sides by 2. We get:

2cosθ = 1
cosθ = 1/2

To find the angle θ, we can take the inverse cosine of both sides to get:

θ = cos-1(1/2)
θ = π/3

Now, let's solve the equation 5cotθ + 4 = 0. We can solve this equation by subtracting 4 from both sides and then dividing both sides by 5. We get:

cotθ = -4/5

To find the angle θ, we can take the inverse cotangent of both sides to get:

θ = cot-1(-4/5)
θ = 4π/3

Therefore, the solution to the equation on the interval [0,2π) is θ = π/3 or θ = 4π/3. To confirm the solutions, we can produce a Desmos graph of the equation on the interval [0,2π). We can see that the points of intersection occur at π/3 and 4π/3, which are our solutions. See the screenshot below.

Answer: Since lines l and m are parallel, we can use the fact that corresponding angles are congruent. Therefore:

m∠1 = m∠6 (corresponding angles)

m∠6 + m∠2 = 180° (supplementary angles, as angles 6 and 2 form a straight line)

m∠2 = m∠7 (corresponding angles)

m∠3 = m∠7 (alternate interior angles)

m∠1 + m∠4 = 180° (supplementary angles, as angles 1 and 4 form a straight line)

m∠3 + m∠4 = 180° (supplementary angles, as angles 3 and 4 form a straight line)

We know that m∠1 = 63°, so we can use the equations above to find m∠6 and m∠7:

m∠1 = m∠6, so m∠6 = 63°.

m∠6 + m∠2 = 180°, so m∠2 = 180° - m∠6 = 180° - 63° = 117°.

m∠2 = m∠7, so m∠7 = 117°.

m∠3 = m∠7, so m∠3 = 117°.

m∠1 + m∠4 = 180°, so m∠4 = 180° - m∠1 = 180° - 63° = 117°.

m∠3 + m∠4 = 180°, so m∠3 + 117° = 180°, which means m∠3 = 63°.

Therefore, the measures of the angles are:

m∠1 = 63°

m∠2 = 117°

m∠3 = 63°

m∠4 = 117°

m∠6 = 63°

m∠7 = 117°

Step-by-step explanation:

Part A: The function f(x) is an exponential function.

Part B: As x increases by 1, the value of f(x) increases by a factor of 6.

It is an exponential function because the function is of the form f(x) = a^(x-1), where a is a constant. We can see that when x increases by 1, the exponent in the function increases by 1 as well. So we have:

f(x+1) = a^x * a

f(x) = a^(x-1)

Therefore, the ratio of f(x+1) to f(x) is:

f(x+1)/f(x) = (a^x * a) / (a^(x-1)) = a

This means that as x increases by 1, the value of f(x) increases by a factor of a, which in this case is 6. Therefore, statement B supports the correct answer from Part A.

Answer:

m<BFC= 64°; m<AFB= 116°

Step-by-step explanation:

Using the Vertical Angle Theorem, in which "the opposing angles of two intersecting lines must be congruent, or identical in value"

m<AFE is congruent to m<BFC, therefore m<BFC is 64°

You can also use the straight angle theorem where BE is a straight line, and is therefore 180°. so subtracting 180° from 64° will result in m<AFB being 116°, you second answer. You can take it a step further without using the vertical angle theorem to get our first answer by using the same rules for the straight angle theorem again, knowing that AC is a straight line and that m<AFB is 116°, subtract 180° by 116° to get m<BFC, 64°.
