900 students attended the school concert. There were twice as many adults as children in the audience. How many children attended the concert? which let statement would you use?
To solve for the number of children at the concert with twice as many adults present in a total of 900 attendees, we let the number of children be x, set up the equation x + 2x = 900, and solve for x to find that there were 300 children.
Explanation:The question pertains to solving a problem involving proportions in a total population. Assuming there are twice as many adults as children at the school concert, we can use a 'let' statement to express the number of children as 'x'. Thus, the number of adults would be '2x' because there are twice as many adults as children. Since the total number of attendees is 900, we can set up the equation: x + 2x = 900.
To find the number of children, we combine like terms to get 3x = 900, and then divide both sides by 3 to find x. Thus, x = 900 / 3, which means x = 300. So, there were 300 children at the concert.
Step-by-Step Solution:Let the number of children be 'x' (let statement).Write the number of adults as '2x' because there are twice as many adults as children.Set up the equation for the total attendees: x + 2x = 900.Combine like terms: 3x = 900.Divide both sides by 3 to solve for x: x = 300.Conclude that there were 300 children at the concert.What is the time 23 hours after 8:00 pm
A donut shop is experimenting with two new types of cream-filled treats, one with raspberry filling, and the other with peach. A batch of raspberry donuts cooks in 11 minutes while a batch of peach donuts cooks in only 8 minutes.
Let x represent the number of raspberry-filled donuts and let y represent the number of peach-filled donuts. Write an inequality to represent how many batches of the new type of donuts can be produced in a 10 hour day.
Answer:
The required inequality is [tex]11x + 8y \leq 600[/tex]
Step-by-step explanation:
Given : A donut shop is experimenting with two new types of cream-filled treats, one with raspberry filling, and the other with peach.
A batch of raspberry donuts cooks in 11 minutes while a batch of peach donuts cooks in only 8 minutes.
Let x represent the number of raspberry-filled donuts and let y represent the number of peach-filled donuts.
To write : An inequality to represent how many batches of the new type of donuts can be produced in a 10 hour day.
Solution :
Time taken to cook the raspberry donuts = [tex]11x[/tex] minutes
Time taken to cook the peach donuts = [tex]8y[/tex] minutes
Donuts produced in 10 hours
1 hours = 60 minutes
10 hours = 60 × 10 = 600 minutes
Total time ≤ 600 minutes
Therefore, the required equation is
→ [tex]11x + 8y \leq 600[/tex]

factor the expression. -x^2+3x+40
To factor the expression -x^2 + 3x + 40, use the method of expanding binomials by comparing coefficients.
Explanation:To factor the expression -x^2 + 3x + 40, we need to find two binomials whose product equals the given expression. Let's set up the expression in the form of (a - b)(c - d) and expand it to compare coefficients.
-x^2 + 3x + 40 = (a - b)(c - d)
By comparing coefficients, we can determine that a, b, c, and d are -x, 5, -8, and 8, respectively. Therefore, the factored form of -x^2 + 3x + 40 is (-x + 8)(x + 5).

Carolyn is building a pen for her dog. The perimeter of the pen is 52 ft
a) Explain how you can use a proportion to convert the perimeter into yards and feet.
b) The fencing material is sold by the yard. It costs 10.99 per yard. What is the cost of material before taxes
Carolyn's dog pen with a 52 ft perimeter is approximately 17.33 yards in length. Fencing material costs $10.99 per yard, making the total cost before taxes around $190.44.
Carolyn is constructing a dog pen with a perimeter of 52 feet. To convert the perimeter from feet to yards, we can use the fact that 1 yard equals 3 feet. Since she is purchasing fencing material by the yard, Carolyn needs to know the total length of fencing in yards. This requires setting up a proportion:
1 yard / 3 feet = x yards / 52 feet
Multiplying both sides by 52 gives us x = 52 / 3 yards. Upon calculating, we find that the pen's perimeter is approximately 17.33 yards.
Since the fencing material costs $10.99 per yard, to find the total cost before taxes, we multiply the number of yards needed by the price per yard:
17.33 yards × $10.99/yard = $190.4367
The cost for the fencing materials before taxes is approximately $190.44.

What two numbers multiply to 80 and add to 28
Final answer:
The task is to find two numbers that multiply to 80 and add to 28. However, after checking possible factors, no such pair of numbers satisfies both conditions. A re-evaluation of the problem may be necessary as the conditions may have been stated incorrectly.
Explanation:
We are looking to find two numbers that when multiplied together equal 80, and when added together equal 28. To solve this problem, we set up a system of equations based on the information given:
By factoring the number 80, we look for factor pairs that also add up to 28. We notice that 16 and 5 are such numbers because:
However, this doesn't meet our second criterion, so we continue searching. Further examination reveals that 20 and 4 are the correct pair because:
In this case, we have not found two numbers meeting both conditions exactly. Therefore, it appears there has been a mistake as no pair of numbers both multiply to 80 and add up to 28. Thus, we either reconsider our pair list or recheck the conditions given.

PTG has side lengths of 18 cm, 14 cm, and 16 cm. which type of triangle is PTG? right, obtuse, acute, isosceles
Final answer:
Triangle PTG is an acute triangle because the sum of the squares of the shorter sides (196 + 256 = 452) is greater than the square of the longest side (324). It is not a right or obtuse triangle, nor is it isosceles.
Explanation:
To determine which type of triangle PTG is, we can use the lengths of its sides (18 cm, 14 cm, 16 cm). A well-known method to identify the type of triangle based on side lengths is by using the Pythagorean theorem, which applies to right triangles.
Specifically, the theorem states that for a right triangle with legs 'a' and 'b', and hypotenuse 'c', the relationship a2 + b2 = c2 holds true.
First, we can check if PTG is a right triangle by ordering the sides in ascending order and assigning the longest side as 'c'(18 cm), and the other two as 'a'(14 cm) and 'b'(16 cm). If PTG were a right triangle, we would expect to see that 142 + 162 equals 182.
Let's perform the calculations:
142 = 196
162 = 256
182 = 324
Adding together the squares of the shorter sides, we get:
196 + 256 = 452
Since 452 is not equal to 324 (182), the triangle is not a right triangle. Next, we can determine if PTG is an obtuse or acute triangle. For an obtuse triangle, we should have a2 + b2 < c2, and for an acute triangle, we should have a2 + b2 > c2. Since 452 is greater than 324, PTG is an acute triangle.

A boat moves 60 kilometers east from point A to point B. There, it reverses direction and travels another 45 kilometers toward point A. What are the total distance and total displacement of the boat?
The total displacement of the boat is therefore 15 kilometers east.
The student is asking about calculating the total distance and displacement of a boat after it has traveled in two opposing directions. To find the total distance, we simply add up the lengths of both trips the boat makes. Since the boat moves 60 kilometers east from point A to point B and then reverses direction to travel another 45 kilometers towards point A, the total distance traveled by the boat is the sum of these two trips:
Distance from A to B = 60 kilometersDistance from B to A = 45 kilometersTotal distance = 60 km + 45 km = 105 kilometersThe total displacement, however, is the vector difference between the final and starting positions. Since displacement is directional, we calculate it by subtracting the westward trip from the eastward trip:
Displacement = 60 km (east) - 45 km (west)Since east is the positive direction, the displacement is 60 km - 45 km = 15 km towards the eastThe total displacement of the boat is therefore 15 kilometers east.
A pack with 6 cans of juice costs 3.48. What it the unit price?
A.0.49 per can B.0.50 per can C.0.58 per can D.0.60 per can**my answer??**
The unit price of one can of juice, when a 6-pack costs $3.48, is $0.58 per can.
The question asks us to calculate the unit price of a juice can when a pack of 6 cans costs $3.48.
To find the unit price, we divide the total cost of the pack by the number of cans in a pack.
In this case, we divide $3.48 by 6, which gives us $0.58.
$3.48 / 6 = $0.58
Therefore, the unit price per can is $0.58.
