Answer:

100 adults and 200 children

Step-by-step explanation:

$10 × 100 = $1000

$5 × 200= $1000

$1000 + $ 1000 = $ 2000

Answer: a combination of 75 adult tickets and 250 student tickets would make $2000

Step-by-step explanation:

A theater wants 2000$ and children’s tickets cost 5$ and adult tickets cost 10$. To find a combination of children and adult tickets that will make 2000$, we would assume a value for either the number of student tickets or adult tickets and assume a variable for the other.

Assuming 250 student tickets and x adult tickets were sold. Therefore,

250 × 5 + 10x = 2000

1250 + 10x = 2000

10x = 2000 - 1250 = 750

x = 750/10 = 75

Therefore the probability of Maria scoring on her next shot is [tex]\frac{1}{4}[/tex].

Step-by-step explanation:

i) Maria scored two goals and missed on her other six shots.

ii) Maria took a total of eight shots on the goal.

iii) On an average Maria scored twice in every eight shots or once in every four shots on the goal. So we can say that the probability of Maria scoring a goal on every shot on goal is one in four or [tex]\frac{1}{4}[/tex].

iv) Therefore the probability of Maria scoring on her next shot is [tex]\frac{1}{4}[/tex].

Find the total miles of all 3 trucks:

790 + 830 + 948 = 2568

Divide the total by the 12 miles per gallon to find total

Gallons used:

2568 / 12 = 214 total gallons

Multiply total gallons by price:

214 x 1.60 = 342.40

Total amount = $342.40

6 groups of 18 buttons would translate into multiplication.

6 x 18 = 108 buttons total that Malia has.

Final answer:

To determine the total number of buttons Malia has, multiply the number of groups (6) by the number of buttons per group (18), resulting in 108 buttons altogether.

Explanation:

The question concerns a basic arithmetic operation of multiplying two numbers together to find the total quantity of items. Malia has 6 groups of 18 buttons each.

To find out how many buttons she has altogether, we need to perform a multiplication of the two numbers. Multiplying the number of groups by the number of buttons in each group gives us:

Multiply the number of groups (6) by the number of buttons per group (18).

6 groups × 18 buttons per group = 108 buttons.

Therefore, Malia has 108 buttons altogether.

Final answer:

To calculate the energy used by a laptop in Joules, multiply its power usage in watts (78.0 W) by the time it was running in seconds (10.0 minutes converted to 600 seconds). The laptop uses 46,800 Joules of energy.

Explanation:

The question asks for the amount of energy used by a laptop computer that has a power rating of 78.0 W when it runs for 10.0 minutes. To find the energy in Joules, we use the equation for energy, which is E = P * t, where E is energy in Joules, P is power in watts, and t is time in seconds.

First, we convert the time from minutes to seconds: 10.0 minutes * 60 seconds/minute = 600 seconds. Then we plug the values into the equation:

E = 78.0 W * 600s = 46,800 J

Therefore, the laptop uses 46,800 Joules of energy.

Answer:

How many boys are there in total? We can't answer correctly until you give us all the information.

Step-by-step explanation:

The percentage of students who like both oranges and apples (x%) is equal to or greater than 34%.

Let's start by representing the students who like oranges as set A and the students who like apples as set B. We are interested in finding the percentage of students who like both oranges and apples, which corresponds to the intersection of sets A and B.

Based on the given information:

Percentage of students who like oranges (A): 70%

Percentage of students who like apples (B): 64%

Percentage of students who like both oranges and apples (x%): ?

Now, let's use set theory notation to represent the information:

A = students who like oranges

B = students who like apples

A ∩ B = students who like both oranges and apples

The total percentage of students who like oranges or apples can be calculated using the principle of inclusion-exclusion:

Percentage(A ∪ B) = Percentage(A) + Percentage(B) - Percentage(A ∩ B)

We know that Percentage(A) = 70% and Percentage(B) = 64%. Let's denote Percentage(A ∪ B) as y% for simplicity.

y% = 70% + 64% - x%

y% = 134% - x%

Since the total percentage cannot exceed 100% (as it represents the whole student population), we can conclude that:

y% ≤ 100%

134% - x% ≤ 100%

x% ≥ 34%

So, the Main Answer is x% ≥ 34%

Answer:

Italian style = 18,000 packages

French style = 14,000 packages

Oriental style = 53,000 packages

Step-by-step explanation:

See the attached figure to represent the question

let the number of packages of Italian style = x

let the number of packages of French style = y

let the number of packages of Oriental style = z

By using the figure we can make the following equations:

0.4x + 0 * y + 0.2z = 17,800

0.3x + 0.5y + 0.3z = 28,300

0.3x + 0.5y + 0.5z = 38,900

Solving the 3 equations together to find x , y and z

Using the calculator:

x = 18,000 ⇒ Italian style packages

y = 14,000 ⇒ French style packages

z = 53,000 ⇒ Oriental style packages

Answer:

The answer to your question is  P = 17(π + 2) or 17π + 34

Step-by-step explanation:

Data

Diameter = 34 cm

Formula

P = rπ + 2r

Process

1.- Find the radius

radius = diameter / 2

radius = 34 / 2

radius = 17 cm

2.- Substitute the values in the formula

P = 17π + 2(17)

3.- Simplification

P = 17π + 34

4.- Factor

P = 17(π + 2)

The perimeter of the semi-circle with a diameter of 34 cm is 51π cm.

The perimeter of a semi-circle can be found by adding the length of the straight edge (which is equal to half the circumference of a full circle) to the diameter. In this case, the diameter is 34 cm.

The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter. Since we only have half of the circle, we divide the circumference by 2 to get the perimeter of the semi-circle.

Therefore, the perimeter of the semi-circle is (πd/2) + d = (π * 34 cm / 2) + 34 cm = 17π cm + 34 cm = 51π cm.

40 kilograms alloy of 20 % copper and 60 kilograms of alloy of 70 % copper is combined to get 100 kg of 50 % copper alloy

Solution:

Th final alloy is 100 kg

Let "x" be the alloy of 20 % copper

Then, (100 - x) is the alloy of 70 % copper

Therefore,we can say,

"x" kilograms alloy of 20 % copper and (100 - x) kilograms of alloy of 70 % copper is combined to get 100 kg of 50 % copper alloy

Therefore, we frame a equation as:

[tex]x \times 20 \% + (100-x) \times 70 \% = 100 \times 50 \%\\\\x \times \frac{20}{100} + (100-x) \times \frac{70}{100} = 100 \times \frac{50}{100}\\\\0.2x + (100-x) \times 0.7 = 0.5 \times 100\\\\0.2x + 70 - 0.7x = 50\\\\-0.5x = -20\\\\x = 40[/tex]

Thus 40 kilograms of 20 % copper

Then, 100 - x = 100 - 40 = 60

Answer:

45 units²

Step-by-step explanation:

The polygon is composed of a rectangle FSCW and Δ FSN

area of rectangle = WC × WF = 9 × 2 = 18 units²

area of triangle = 0.5 × FS × perpendicular height from vertex N

A = 0.5 × 9 × 6 = 27 units²

Area of polygon = 18 + 27 = 45 units²

The area of a polygon is calculated using geometric formulas based on the shape and dimensions of the polygon.

Regular polygons and composite shapes require specific formulas, while irregular polygons might need more advanced techniques.

To determine the area of a polygon, we use the concept that the area is a measure of the two-dimensional space inside the boundary of a polygon.

A polygon is made of line segments that connect in a closed chain.

Given the description and assuming the polygon is regular or can be divided into recognizable shapes such as triangles, rectangles, or circles, we can use various geometric formulas to calculate the area.

For example, if the polygon is a rectangle, the area is the product of its length and width.

If the polygon can be divided into a series of triangles, we can calculate the area of each and sum them up.

In more complex scenarios, such as irregular polygons, we might need to use methods like triangulation or calculus, depending on the information provided.
