The compound inequality that represents all the possible amounts of money Kyle could have in terms of x are :
4 + 2x < 56
4 + 2x ≥ 38
The least amount of money Lana could have is 17 dollars
How to write a compound inequality ?Lana has x dollars.
Therefore,
Lana money = x dollars
Kyle has $4 more than twice as much money as Lana.
Kyles money = 4 + 2x
Kyle does not have enough money to buy a video game that costs $56, but he has enough money to buy a textbook that costs $38.
Therefore,
4 + 2x < 56
4 + 2x ≥ 38
Hence, the least amount of money Lana could have is as follow:
4 + 2(17) ≥ 38
4 + 34 ≥ 38

Solve x+8y/4=9y for x
Answer:
x = 7y
Step-by-step explanation:
x+8y/4=9y
Multiply each side by 4 to get rid of the fractions
4(x+8y/4)=9y*4
Distribute
4x +8y = 36y
Subtract 8y from each side
4x +8y-8y = 36y-8y
4x = 28y
Divide each side by 4
4x/4 = 28y/4
x = 7y
x+8y/4=9y
Multiply each side by 4
4(x+8y/4)=9y*4
=>4x +8y = 36y
Subtract 8y from each side
=>4x +8y-8y = 36y-8y
=4x = 28y
Divide each side by 4
=>4x/4 = 28y/4
x = 7y
5. A standard-size volleyball court has an
area of 1,800 square feet. The length of the
court is 60 feet. What is the width of the
court?
Answer: The width of the court is 30 feet.
Step-by-step explanation:
We know that the area of a rectangle is given by :-
Area = length x width (1)
Given : A standard-size volleyball court has an area of 1,800 square feet.
The length of the court is 60 feet.
To find : The width of the court.
According to (1) , we have
[tex]1800 = 60\times \text{width}[/tex]
Then,
[tex]\text{Width}=\dfrac{1800}{60}=30[/tex]
Hence, the width of the court is 30 feet.
Final answer:
The width of a standard-size volleyball court, with an area of 1,800 square feet and a length of 60 feet, is calculated to be 30 feet using the formula for the area of a rectangle.
Explanation:
To find the width of a standard-size volleyball court with an area of 1,800 square feet and a length of 60 feet, we need to use the formula for the area of a rectangle, which is Area = length × width. Since we know the area and the length, we can solve for the width.
Let the width be w feet.
Then, 1,800 sq ft = 60 ft × w ft,
So, w = 1,800 sq ft / 60 ft,
Therefore, w = 30 feet.
The width of the volleyball court is 30 feet.

Serenity Spa charges $59 for a one hour massage. They charge $0.95 per minute for each additional minute over an hour. If
x represents the number of minutes over one hour, which of the following functions represents the cost of a massage?
Answer:
D. y = 0.8x + 79
Choices:
A.
y = 79x + 0.8
B.
y = -0.8x + 79
C.
y = 79.8x
D.
y = 0.8x + 79
The following functions represent the cost of a massage as: Cost = 59 + 0.95x
What is the Linear function?A linear function is defined as an equation in which the highest exponent of the variable is always one.
A one-hour massage at Serenity Spa costs $59 USD. They charge $0.95 per minute for every minute over an hour.
The cost of a massage can be represented by the function:
Cost = 59 + 0.95x
This function states that the cost of the massage is equal to the base cost of $59 plus an additional charge of $0.95 for each minute over an hour (represented by the variable x).
For example, if the massage lasts for 70 minutes (10 minutes over an hour), the cost would be calculated as:
Cost = 59 + 0.95(10) = 59 + 9.5 = $68.50

Given that,
A sequence is defined by the recursive function:
[tex]f(n+1) = \frac{1}{3} \times f(n)[/tex] ------ eqn 1
Given that,
[tex]f(3) = 9[/tex]

Answer is 4
Answer: 4
Step-by-step explanation:
8/3 ÷ 2/3 = 4
In Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction.
The first step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 2/3 is 3/2.
8/3 × 3/2
Next, multiply the two numerators. Then, multiply the two denominators. In this step, we first cancel by a common factor of 3, which then gives 8/2, then cancel by another common factor of 2, which gives 4.
Thus 8/3 x 3/2 = 4

Step-by-step explanation:
[tex]\frac{10}{3}[/tex] = [tex]\frac{k}{9}[/tex]
We can easily solve this by cross multiplying. Multiply 10 by 9, and multiply the variable (k) by 3.
10 x 9 = 90
3 x k = 3k

3k = 90
Solve for k.
3k/3 = 90/3
k = 30

**A rock dropped from a 100 foot tower.
The height of the rock as a function of time
can be modeled by the equation: h(t) =
- 16t2 + 10t + 100. How long does it take
for the rock to reach the ground?
Final answer:
The rock takes approximately 2.032 seconds to reach the ground.
Explanation:
The height of the rock can be modeled by the equation h(t) = -16t² + 10t + 100, where h(t) is the height of the rock and t is the time in seconds. To find the time it takes for the rock to reach the ground, we need to solve the equation when h(t) is equal to zero. We can do this by setting the equation equal to zero and using the quadratic formula.
Using the quadratic formula, we get: [tex]t = (-b \± \sqrt(b^2 - 4ac))/(2a)[/tex]
Plugging in the values of a, b, and c from the equation, we get: [tex]t = (-10 \± \sqrt{10^2 - 4(-16)(100)/2(-16)[/tex]
Simplifying, we get: [tex]t = (-10 \± \sqrt{100 + 6400/(-32)[/tex]
Continuing to simplify, we get: [tex]t = (-10 \± \sqrt{6500/(-32)}[/tex]
So, it takes approximately 2.032 seconds for the rock to reach the ground.

how to write 137% as a fraction and decimal
Answer: 1.37 and 137/100
Step-by-step explanation:
hope this help make me brainliest plest thanks
Final answer:
137% can be written as the fraction 137/100, which is already simplified. To convert 137% to a decimal, divide 137 by 100 to get the decimal 1.37.
Explanation:
To write 137% as a fraction, you should consider that percent means 'per hundred.' Therefore, 137% can be written as a fraction with a denominator of 100: 137/100, which is already in its simplest form.
To express 137% as a decimal, you divide the numerator by the denominator. In this case, you would divide 137 by 100. This gives you the decimal 1.37, which is the decimal equivalent of 137%.
Understanding these conversions is crucial when working with percentages, and they can often simplify calculations in various mathematical problems.

Angles 1 and 3 are directly across from each other.
They are called vertical angles. They share only a
vertex. They always measure the same. Therefore,
if angle 1 measures 27 degrees, angle 3 will
measure
degrees.
The measure of angle 3 is 27 degrees.
Step-by-step explanation:
The angles 1 and 3 are vertical angles and share same vertex.Therefore, the measure of the angle 1 and angle 3 are equal.Given,
angle 1 = 27°
Since angle 3 is same as angle 1, the measure of angle 3 is also 27 degrees
angle 3 = 27°.
Kiran and 3 of his friends are going to split the lunch bill of $24.48 how much will each person pay
To split a $24.48 lunch bill between Kiran and 3 friends ,,divide the total by 4, resulting in each person paying $6.12.
Kiran and 3 of his friends want to split the lunch bill of $24.48 evenly. Since there are 4 people in total, we simply divide the total bill by 4 to find out how much each person will pay. Here's the step-by-step calculation:
Find the total number of people: 1 (Kiran) + 3 friends = 4 people.Divide the total bill by the number of people: $24.48 ÷ 4.Perform the division to find the amount per person: $24.48 ÷ 4 = $6.12.Therefore, each person will pay $6.12 to split the lunch bill of $24.48 equally.
