1.Your brother and some of his friends, all under 12 years old, went to the movies. They paid $60 for their tickets. What equation could describe the situation?

2.Another family went to the movies. They bought some child tickets and some adult tickets and spent $96 altogether.
What equation could describe the situation?
How would the equation change if a child’s ticket cost $10?
How would the original equation change if the total price spent on the tickets were $156?

Given:

Money they've already saved = $270

Trip will cost at least $500.

To find:

The amount they need to save more in order to make enough for the trip.

Solution:

Let they need $x more.

Money they've already saved = $270

Total money they will have = $(x+270)

Now, the trip will cost at least $500. It means, they need $500 or more than that. So, total money they will have needs to be greater than or equal to 500.

\(x+270\geq 500\)

\(x\geq 500-270\)

\(x\geq 230\)

Therefore, they need $230 or more than that to make enough for the trip.

There are 70 ways to split 8 people into two teams of 4. There are 1680 ways to split 9 people into 3 teams of 3. There are 945 ways to choose 2 teams of 4 from 10 prospects.

To find the number of ways to split 8 people into two teams of 4, we can first choose the first team in $\binom{8}{4} = 70$ ways, and the second team will be the remaining 4 people.

To split 9 people into 3 teams of 3, we can first choose the first team in $\binom{9}{3} = 84$ ways. After this, we are left with 6 people, from which we choose the second team in $\binom{6}{3} = 20$ ways. The final team will be the remaining 3 people.

To choose 2 teams of 4 from 10 prospects, we can first choose the first team in $\binom{10}{4} = 210$ ways. After this, we are left with 6 people, from which we choose the second team in $\binom{6}{4} = 15$ ways. However, since the order in which we choose the two teams does not matter, we must divide by 2 to get the final answer of $\frac{210 \cdot 15}{2} = 945$.

The equation 2 = -x√(x + 2) - x has two potential solutions: x = -1 and x = -8. However, x = -8 does not satisfy the equation, so the set of all solutions is {x = -1}.

To find the set of solutions to the equation 2 = -x√(x + 2) - x, we can solve it algebraically.

Starting with the given equation, we can simplify it step by step:

2 = -x√(x + 2) - x

Adding x to both sides:

2 + x = -x√(x + 2)

Squaring both sides to eliminate the square root:

(2 + x)^2 = (-x√(x + 2))^2

Expanding and simplifying:

4 + 4x + x^2 = x^2(x + 2)

Simplifying further:

4 + 4x = x^3 + 2x^2

Rearranging terms:

x^3 + 2x^2 - 4x - 4 = 0

Factoring the equation:

(x + 1)(x^2 + x - 4) = 0

Setting each factor to zero:

x + 1 = 0 or x^2 + x - 4 = 0

Solving the first equation, we find x = -1.

For the second equation, we can use the quadratic formula:

x = (-1 ± √(1^2 - 4(1)(-4))) / (2(1))

x = (-1 ± √(1 + 16)) / 2

x = (-1 ± √17) / 2

However, when we substitute x = (-1 + √17) / 2 into the original equation, it does not satisfy the equation. Therefore, x = -8 is not a solution.

Hence, the set of all solutions to the equation is {x = -1}.

Projectile motion is the motion of an object (known as a projectile) that is launched or thrown and then moves under the influence of gravity alone. In this type of motion, the object moves in a curved path called a parabola.

Projectile motion refers to the motion of an object that is launched or thrown into the air and then moves under the influence of gravity alone.

The motion of the object can be described as a combination of horizontal motion with a constant velocity and vertical motion with a constant acceleration due to gravity.

The path of the projectile is determined by its initial velocity, the angle at which it is launched, and the acceleration due to gravity. The acceleration due to gravity is always acting vertically downwards and is constant at 9.8 m/s².

The volume of a triangular pyramid is V=(1/3)Ah, where A is the area of the triangular base and h is the height.

First, let's find A, the area of the base. The area of a triangle is bh/2, where b is the base and h is the height.

In this question, 5 is the base and 15 is the height, so A=5*15/2=75/2.

Now we know A is 75/2, so let's go back to the formula for the volume of a pyramid. We are given h is 22, so

V=(1/3)(75/2)*22=275

The answer of the given question based on the interest rate the answer is  the premium paid for each subsequent year would be ¢840

A premium rate is price per unit of insurance coverage for specific risk that an insurer charges its policyholders. It is typically expressed as  percentage of  total insured value of  policy.

To calculate the premium paid for subsequent years, we need to know what the premium rate is for those years. The premium rate may change from year to year depending on various factors such as the age of the car, the driver's record, etc.

Assuming the premium rate remains constant at 8% of the insured value for all subsequent years, we can calculate the premium paid for each year as follows:

First year: 8% of ¢10,500 = ¢840

Second year: 8% of ¢10,500 = ¢840

Third year: 8% of ¢10,500 = ¢840

And so on...

So the premium paid for each subsequent year would be ¢840 if the premium rate remains constant at 8% of the insured value.

Answer:

31.76 ft and 58.64 ft

Step-by-step explanation:

The radius measures between 13 feet and 24 feet.

The wheel is able to turn 7π/9 radians before getting stuck.

We need to find the range of distances that the wheel could spin before getting stuck. That is, the length of arc.

Length of an arc is given as:

\(L = \frac{\theta}{2\pi} * 2\pi r\)

where θ = central angle = 7π/9 radians

r = radius of the circle

Therefore, for 13 feet:

\(L = \frac{7\pi}{18 \pi} * 2 * \pi * 13\\\\L = 31.76 ft\)

For 24 feet:

\(L = \frac{7\pi}{18 \pi} * 2 * \pi * 24\\\\L = 58.64 ft\)

The wheel could spin between 31.76 ft and 58.64 ft before getting stuck.

Here is the answer for the problem I believe

Answer:

Mr. A initially paid approximately N8000 for the land.

Step-by-step explanation:

Step 1: Let's assume Mr. A initially purchased the land for a certain amount, which we'll call "x" in currency units.

Step 2: Mr. A sold the land to Mr. B at a profit of 10%. This means Mr. A sold the land for 110% of the amount he paid (1 + 10/100 = 1.10). Therefore, Mr. A received 1.10x currency units from Mr. B.

Step 3: Mr. B sold the land to Mr. C at a gain of 5%. This means Mr. B sold the land for 105% of the amount he paid (1 + 5/100 = 1.05). Therefore, Mr. B received 1.05 * (1.10x) currency units from Mr. C.

Step 4: According to the given information, Mr. C paid N1240 more for the land than Mr. A paid. This means the difference between what Mr. C paid and what Mr. A paid is N1240. So we have the equation: 1.05 * (1.10x) - x = N1240

Step 5: Simplifying the equation: 1.155x - x = N1240

Step 6: Solving for x: 0.155x = N1240

x = N1240 / 0.155

x ≈ N8000

Therefore, in conclusion, Mr. A initially paid approximately N8000 for the land.

Answer:

a = 55

b = 13

c = 8

Step-by-step explanation:

2a - 5 = 105° (alternate exterior angles are congruent)

Add 5 to both sides

2a - 5 + 5 = 105 + 5

2a = 110

Divide both sides by 2

2a/2 = 110/2

a = 55

(2a - 5) + (5b + 10) = 180° (consecutive interior angles/same side interior are supplementary)

Plug in the value of a

2(55) - 5 + 5b + 10 = 180

110 - 5 + 5b + 10 = 180

Add like terms

115 + 5b = 180

Subtract 115 from each side

115 + 5b - 115 = 180 - 115

5b = 65

Divide both sides by

5b/5 = 65/5

b = 13

10c - 5 = 5b + 10 (corresponding angles are congruent)

Plug in the value of b

10c - 5 = 5(13) + 10

10c - 5 = 65 + 10

10c - 5 = 75

Add 5 to both sides

10c - 5 + 5 = 75 + 5

10c = 80

Divide both sides by 10

10c/10 = 80/10

c = 8

The measure of Angle A in degrees is approximately 219.99 degrees

To find the measure of Angle A in degrees, we need to consider the given information: the circle is centered at the vertex of Angle A, the subtended arc is 4.4 cm long, and \(\frac{1}{360}\)th of the circle's circumference is 0.02 cm.

Step 1: Calculate the circumference of the circle.
Since 1/360th of the circumference is 0.02 cm, we can find the entire circumference by multiplying 0.02 cm by 360.
Circumference = 0.02 cm (360) = 7.2 cm

Step 2: Determine the proportion of the circumference that corresponds to the subtended arc.
Divide the length of the arc (4.4 cm) by the circumference (7.2 cm).
\(Proportion = \frac{4.4}{7.2} = 0.6111\)

Step 3: Calculate the measure of Angle A in degrees.
Since the proportion corresponds to the fraction of the circle's circumference, we can find the angle by multiplying this proportion by 360 degrees.
Angle A = 0.6111 (360 degrees) =219.99 degrees

The measure of Angle A in degrees is approximately 219.99 degrees.
