The value of n(B) in the set is 23

From the question, we have the following parameters that can be used in our computation:

n(A) = 108, n(A ∪ B) = 160, and n(A ∩ B) = 43,

The value of n(B) is calculated as

n(A u B) = n(A) + n(B) - n(A n B)

Substitute the known values in the above equation, so, we have the following representation

160 = 108 + n(B) - 43

This gives

n(B) = 160 + 43 - 180

Evaluate

n(B) = 23

Answer:B. 1.50(5) + 2.00m ≤ 19.00

Step-by-step explanation:This inequality can be used to determine the maximum number of milkshakes that Donna can buy with her $19.00. The expression on the left side of the inequality represents the total cost of her purchase and the expression on the right side of the inequality represents the amount of money she has to spend. Since she must buy 5 ice cream cones, that is represented by the 1.50(5) term. The 2.00m term represents the cost of the milkshakes she can buy, with m representing the number of milkshakes. The inequality states that the total cost of her purchase must be less than or equal to the amount of money she has to spend, so the maximum number of milkshakes she can buy can be determined by rearranging the expression.

If Donna buys 5 ice cream cones, that adds up to, £10.00.

She is then left with £9.00.

9 divided by 1.50 = 6.

She is able to buy 6 milkshakes with the money she has left. However, she is now left with no money.

The answer would be B.1.50(5) +2.00m≤19.00

Answer:

40

Step-by-step explanation:

Assign the variable x to Devaughn's age. If Devaughn is 7 years older than Sydney, then Sydney must be 7 years younger than him, so the expression x - 7 can represent Sydney's age.

The sum of their ages would be x + x - 7 or 2x - 7 which is also said to equal  87. Therefore, this can be written as an equation and be solved accordingly:

2x - 7 = 87

2x = 94

x = 47

Therefore, Devaughn is 47 and Sydney, who is 7 years younger, is 40.

Sydney's age is determined by setting up and solving a simple algebraic equation based on the information provided. The equation that represents this situation is S + (S + 7) = 87, which leads to the conclusion that Sydney is 40 years old.

Devaughn is 7 years older than Sydney. Given that the sum of their ages is 87, we can represent this situation with algebra. Let's denote Sydney's age as S.

Considering Devaughn is 7 years older, we can represent his age as S + 7. Given that the sum of their ages is 87, we can write down this equation: S + (S + 7) = 87.

Solving this equation will help us find Sydney's age. First, simplify the left side: 2S + 7 = 87. Then, subtract 7 from both sides: 2S = 80. Finally, divide both sides by 2 to solve for S, yielding Sydney's age: S = 40.

The given expression is a logarithm expression. The value of the log expression is -112.

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one math operation, and a sentence. It's possible to multiply, divide, add, or subtract with this mathematical operation.

The given expression is log (³√c⁵)/(a⁷b⁸).

The value of log a = 7, log b = 11, log c = 15

Applying the quotient formula log(a/b) = log a - log b in the given expression:

= log (³√c⁵) - log (a⁷b⁸)

Again applying the product formula log (ab) = log a + log b:

= log (³√c⁵) - log (a⁷) - log b⁸

Apply the power rule log (a^b) = b log a:

= (5/3) log c - 7log a - 8log b

Now putting the value of log a = 7, log b = 11, log c = 15:

= (5/3) × 15 - 7 × 7 - 8 × 11

= 5×5 - 49 - 88

= -112

It will take 5 minutes to paint this cone

Since the area of the base of the cone is doubled, the new base area becomes 2 * 49π in² = 98π in².

The radius of the original cone can be found by using the formula for the area of a circle:

49π = πr^2

r = 7 in

The height of the new cone can be calculated using the same lateral height as the original cone:

h = 8 in

Using the formula for the volume of a cone, we can calculate the volume of the new cone:

V = (1/3)πr^2h = (1/3)π(7^2)(8) = (1/3)π(392)

The surface area of the original cone can be found using the formula for the surface area of a cone:

A = πr^2 + πrs

where s is the slant height of the cone.

s = √(r^2 + h^2) = √(7^2 + 8^2) = √(49 + 64) = √(113)

So, we have

A = πr^2 + πrs = π(7^2) + π(7)(√(113)) = 49π + 7π(√(113))

The surface area of the new cone can be found using the same formula:

A = πr^2 + πrs = π(7^2 * 2^2) + π(7 * 2)(√(113)) = 98π + 14π(√(113))

When the equations are compared, we have

2 * 49π + 7π(√(113)) = 98π + 14π(√(113))

Since the new cone has twice the surface area of the original cone and can be painted at the same rate,

It will take 2.5 * 2 = 5 minutes to paint this cone.

The domain is the set of possible x values. The function has values from below five while not including 5(as shown by the open circle). Therefore the domain would be ( - ∞, 5). (Open brackets are non-inclusive while closed brackets are inclusive).

The range is the set of possible y values. The minimum of this graph seems to be at y = -3, and there is not a maximum as while the x values decrease, the y-values infinitely increase. Therefore, the range is [- 3, ∞)

In mathematics, a percentage is any amount that can be stated as a proportion of 100. Also occasionally used are the abbreviations "pct.," "pct," or "pc." But the "%" mark is usually used to indicate it. The proportional amount is flat and lacks any dimensions. Since percentages have a numerator of 100, they can be thought of as fractions. A number should be preceded by the percent sign (%) to denote it is a percent.

Here,

Given :
