demarcus has at least $8 more than his older sister. His older sister had $4. Which of the following inequalities could be used to find how much money m demarcus has?

they all split it and is each going to have 6 dollars each plus the extra 2 for cleaning so 8 dollars each.

Answer - $8 Dollars

Each girl received a total of $8 after dividing the $24 from gardening equally among four girls and adding an extra $2 given by Mrs. Day for cleaning up.

The question asks how much money each girl received in total for helping with gardening and cleaning up. To find the answer, we first calculate how much each girl got from the $24 shared equally and then add the additional money each received from Mrs. Day.

Therefore, each girl received $8 in total from helping Mr. and Mrs. Day with gardening and cleaning up.

Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side.

Coterminal angles are angles that have the same terminal sides in standard position.

Anytime we complete a full cycle( a complete revolution) we come back to the same terminal side.

Therefore to find all angles which are coterminal with [tex]-271\degree[/tex] we keep adding or subtracting [tex]360\degree[/tex].

For the given interval, that is, [tex]0\degree[/tex] to [tex]360\degree[/tex],

We add [tex]360\degree[/tex] so that we can obtain an angle coterminal with [tex]-271\degree[/tex] within this interval.

This means that

[tex]-271\degree[/tex] is coterminal with [tex]360\degree + \: -271\degree=89\degree[/tex]

Hence the correct and answer is D

The product is 3 because -3/4 * -4 is 3

From my research i found the answer to be that he rented 9 movies.

Final answer:

To find out how many movies Andrew rented, subtract the membership fee from the total bill, then divide by the cost per movie. This reveals Andrew rented 9 movies.

Explanation:

To solve how many movies Andrew rented this month, we first need to subtract the monthly membership fee from the total bill. Knowing the monthly membership fee is $5.00 and the total bill was $16.25, we can calculate the cost of movies rented alone.

First, subtract the membership fee from the total bill: $16.25 - $5.00 = $11.25. This is the amount spent on renting movies.

Next, divide the result by the cost per movie, which is $1.25 per movie. This gives us: $11.25 / $1.25 = 9.

Therefore, Andrew rented 9 movies this month.

Pythagorean Theorem:  

500^2 = 300^2 + x^2  

250,000 = 90,000 + x^2  

160,000 = x^2  

x = +/- 400 use the positive root  

height is 400ft

The kite is 400 feet above the ground.

To determine how high the kite is above the ground if it is 500 feet of string out and the horizontal distance between Tyler and the kite is 300 feet, we can use the Pythagorean theorem. This theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides (the adjacent and opposite sides).

In this scenario, imagine a right triangle where the string of the kite represents the hypotenuse, the horizontal distance from Tyler to the point directly underneath the kite represents the adjacent side, and the height of the kite above the ground represents the opposite side.

The length of the hypotenuse (the string) is given as 500 feet, and the length of the adjacent side (the horizontal distance) is 300 feet. To find the height of the kite (the opposite side), we apply the Pythagorean theorem:

[tex]\( c^2 = a^2 + b^2 \rightarrow 500^2 = 300^2 + b^2 \rightarrow 250000 = 90000 + b^2 \rightarrow \\b^2 = 250000 - 90000 \rightarrow b^2 = 160000 \rightarrow b = \sqrt{160000} \rightarrow b = 400 )[/tex]

Therefore, the height of the kite above the ground is 400 feet.

Answer:

[tex]t=5x[/tex]

Step-by-step explanation:

So the number of questions in an exam varies with the number of minutes to take the exam.

For each question there are 5 minutes allotted.

Lets say that there are 'x' number of questions in the exam and 't' is the total time taken to finish the exam, in minutes. So the time taken to complete the exam would be

[tex]5 \times x=5x[/tex]

Therefore, the equation relating the time taken to complete the exam and the number of questions is given by:

[tex]t=5x[/tex]

So there are two variables in the equation, 't', and 'x':

t - time taken to complete the exam

x - number of questions on the exam

Answer: There will be two different ways of doing so.

Step-by-step explanation:

Since we have given that

Total number of rocks =38

If we want to groups of 10 rocks or as single rocks then there are 2 different ways ;

Case I:

if we group into 10 rocks

there will be four sets in which Ist set contains 10 rocks

Second set contains 10 rocks

Third set contains 10 rocks

and Fourth set remains with 8 rocks only.

Case II:

if we group as single rocks .

There will be 38 sets .

The husband earns $42,000 per year.

Let's denote the husband's earnings as H.

According to the problem, the wife earns 16,000 less than twice what her husband earns. So, the wife's earnings can be represented as (2H - 16,000).

We know that together they earn 110,000 per year. This can be written as:

H + (2H - 16,000) = 110,000

Combining like terms, this equation simplifies to:

3H - 16,000 = 110,000

Add 16,000 to both sides to solve for H:

3H = 126,000

Divide both sides by 3:

H = 42,000

Therefore, the husband earns $42,000 per year.

ANSWER

[tex]x=\frac{14.5\degree}{3}+120\degree n\:or\:x=\frac{165.5\degree}{3} +120\degree n[/tex], for [tex]n\ge 0[/tex], where [tex]n[/tex] is an integer.

EXPLANATION

We want to solve the trigonometric equation;

[tex]Sin(3x)=\frac{1}{4}[/tex]

Since sine ratio is positive, it means the argument,[tex](3x)[/tex] is either the first quadrant or second quadrant.

This implies that;

[tex](3x)=arcsin(\frac{1}{4})[/tex]

[tex](3x)=14.5\degree[/tex] in the first quadrant.

Or

[tex](3x)=180\degree-14.5\degree=165.5\degree[/tex] in the second quadrant.

Since the sine function has a period of [tex]360\degree[/tex], The general solution is given by

[tex](3x)=14.5\degree+360\degree n\:or\:(3x)=165.5\degree +360\degree n[/tex],for [tex]n\ge 0[/tex], where [tex]n[/tex] is an integer.

Dividing through by 3, we obtain the final solution to be;

[tex]x=\frac{14.5\degree}{3}+120\degree n\:or\:x=\frac{165.5\degree}{3} +120\degree n[/tex], for [tex]n\ge 0[/tex], where [tex]n[/tex] is an integer.

Final answer:

The Miami Dolphins scored 14 points, while the Buffalo Bills scored 52 points, totaling 66 points as per the equation representing their scores.

Explanation:

Let's denote the number of points the Miami Dolphins scored as D. According to the question, the Buffalo Bills scored 24 more than twice the number of points that the Miami Dolphins did. This can be expressed as 2D + 24 for the Buffalo Bills' score. The total points scored by both teams is given as 66.

We can set up an equation to represent this situation:

D + (2D + 24) = 66

Simplify and solve for D:

Combine like terms: 3D + 24 = 66

Subtract 24 from both sides: 3D = 42

Divide both sides by 3: D = 14

So, the Miami Dolphins scored 14 points. We can then calculate the Buffalo Bills' score by plugging D into the Buffalo Bills' score equation:

2(14) + 24 = 28 + 24 = 52

Therefore, the Buffalo Bills scored 52 points.

In conclusion, the Miami Dolphins scored 14 points, and the Buffalo Bills scored 52 points.

B is your answer.

(1000x0.0325)/100= 32.50.

Step 1. Add 72 to both sides

5y = 7 + 5x + 72

Step 2. Simplify 7 + 5x + 72 to 5x + 79

5y = 5x + 79

Step 3. Divide both sides by 5

y = 5x + 79/5

After 5 months, they would both have the same cost. If you were to cancel after 9 months, you would cancel $320 for the first option and $360 for the second option.

To solve this, you need to create an equation. You get $50+30x and let x=number of months. This would tell you how much you need to pay for option 1. In option 2, you would have $40x. This is because there is no setup fee and so there would only be the monthly cost.We then set thos equations both equal to each other because the first question asks for the options to be the same price. For the second question, you would need to substitute 9 for the x in those equations. That would have you find out which is more expensive.

Answer:

So, given a quadratic function, y = ax2 + bx + c, when "a" is positive, the parabola opens upward and the vertex is the minimum value. On the other hand, if "a" is negative, the graph opens downward and the vertex is the maximum value.

Step-by-step explanation:

100% on edg :)

The quadratic function, y = ax²+ bx + c opening upward if the value of 'a' is positive.

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

We have quadratic function,

y = ax² + bx + c

If the value of 'a' is negative, then the function will be opening downside and if the value of 'a' is positive, then the function will be opening upside.

Let say a = 1, b = 1, c = 1

y = x² + x + 1 (upside)

If a = -1, b = 1, c = 1

y = -x² + x + 1 (downside)

Thus, the quadratic function, y = ax²+ bx + c opening upside if the value of 'a' is positive.
