The numerical expression 4[(6 - 1) + 3(5 - 2)] evaluates step-by-step following the order of operations. Operations within the parentheses are performed first, followed by multiplication, resulting in a final answer of 56
The student's question involves evaluating a numerical expression, which is a concept in mathematics. We have the expression 4[(6 - 1) + 3(5 - 2)] and want to calculate its value step by step following the order of operations:
First, perform the operations inside the parentheses: (6 - 1) = 5 and (5 - 2) = 3.Next, multiply by 3 within the parentheses: 3(5 - 2) becomes 3 * 3 = 9.Now, add the results within the square brackets: 5 + 9 = 14.Finally, multiply the result by 4: 4 * 14 = 56.Hence, the correct answer to the expression is 56

Suppose a college student pays $700 for tuition fees. However, she also has to pay $400 for her textbooks (ouch!). What percent of her total education costs does she pay for her books? Write your answer to the nearest tenth of a percent, but in decimal form.
The student spends approximately 40% of her total education costs on her books, represented as 0.4 in decimal form.
Explanation:The student's total education costs are the sum of the tuition fees ($700) and the cost of her books ($400). This comes to a total of $700 + $400 = $1100. The percent of the total education cost that is spent on books is then given by the cost of the books divided by the total cost, or $400 / $1100. When expressed as a decimal, this works out to be approximately 0.36 or 36%, but since we want to the nearest tenth of a percent in decimal form, it becomes 0.4 or 40% to the nearest tenth. Therefore, the student spends 40% of her total education costs on her books.

You buy 8 gallons of gasoline at p dollars per gallon and pay $23.20. Write an equation to find the price of one gallon of gasoline. Then find the price of one gallon of gasoline.
Answer:
The price of 1 gallon of gasoline is $2.90.
Step-by-step explanation:
You buy 8 gallons of gasoline at p dollars per gallon and pay $23.20.
We get the expression:
[tex]8p=23.20[/tex]
We can find one gallon as: p=[tex]\frac{23.20}{8}[/tex]
=> p = $2.90
Hence, the price of 1 gallon of gasoline is $2.90.

Perform the operation given that a = {−3, −2, −1, 0, 1, 2, 3}, b = {−4, −2, 0, 2, 4}, and c = {0, 1, 2, 3, 4}. (enter your answers as a comma-separated list.) b ∪ (a ∩ c)
Final answer:
The operation b \\u222a (a \\u2229 c) combines the unique elements of set b with the intersection of sets a and c, resulting in the set {-4, -2, 0, 1, 2, 3, 4}.
Explanation:
The student is asked to perform the operation b \\u222a (a \\u2229 c), given three sets a, b, and c. To do this, we need to first find the intersection of sets a and c, which is the set of elements that are both in a and in c. Then we find the union of set b with this intersection, which includes all the elements that are either in b or in the intersection of a and c.
Set a: {-3, -2, -1, 0, 1, 2, 3}
Set b: {-4, -2, 0, 2, 4}
Set c: {0, 1, 2, 3, 4}
First, find the intersection: a \\u2229 c = {0, 1, 2, 3}.
Next, find the union with set b: b \\u222a (a \\u2229 c) = {-4, -2, 0, 1, 2, 3, 4}.
The final result is the set {-4, -2, 0, 1, 2, 3, 4}, which contains all unique elements from both sets b and the intersection of a and c.

An angle is 5 times the measure of its complement. find the measure of the larger angle
Answer:
75°
Step-by-step explanation:
The angle is our unknown, so we will call it x. If x is the angle, then its complement is 90 - x (complementary angles add up to 90). The word "is" means "equals", and "5 times" is multiplying the complementary by 5:
x = 5(90 - x) so
x = 450 - 5x
Combine like terms to get
6x = 450 so
x = 75
The other angle, the complement to that angle, is 90 - 75 = 15
The larger angle is 75°

Mr. Miller owns two hotels and is ordering towels for the rooms. He ordered 27 hand towels and 48 bath towels for a bill of $540 for the first hotel. He ordered 50 hand towels and 24 bath towels for a bill of $416 for the other hotel. What is the cost of one hand towel and one bath towel?
This question is based on the concept of solving a two linear equation.
Thus, the cost of one bath towel is $9 and one hand towel is $4.
Given:
Number of ordered of hand towels is 27 and bath towels is 48 and for a bill of $540 for the first hotel.
Number of ordered of hand towels is 50 and bath towels is 24 and for a bill of $416 for the other hotel.
We need tom determined the cost of one hand towel and one bath towel.
According to the question:
Let the hand towels be h and bath towels be b.
Therefore, equation of first hotel is
27h + 48b = 540........(1)
Equation of second hotel is
50h + 24b = 416.........(2)
Now, solving both equation for h and b.
Equation (2) multiplying by -2.
-100 h -48 b = - 832..................(3)
Now, solve equation (1) and (3)
27h + 48b = 540 and -100h - 48b = - 832
⇒ -73 h = - 292
⇒ h = -292 / -73
⇒ h = 4
Therefore, the cost of 1 hand towel is $4.
Now, putting the value of h = 4 in equation (1).
⇒ 27(4) + 48b = 540
⇒ 108 + 48b = 540
⇒ 48b = 540 - 108
⇒ 48b = 432
⇒ b = 432/48
⇒ b = 9
Therefore, the cost of 1 bath towel is $9.
Thus, the cost of one bath towel is $9 and one hand towel is $4.
