Describe the solution to the inequality p>4
Answer:
P is greater than 4
Step-by-step explanation:
so P could be anything from 5 to infinity
Final answer:
The inequality p > 4 is satisfied by any real number greater than 4. The solution is represented visually by shading the number line to the right of the open circle at 4.
Explanation:
The solution to the inequality p > 4 is all real numbers greater than 4. In other words, for any number p that is greater than 4, the inequality will hold true.
To visualize this solution on a number line, you would draw an open circle at 4 and shade all numbers to the right of 4, indicating that all those numbers are part of the solution set.
This is a basic concept in algebra, focusing on understanding and solving inequalities. The solution does not include the number 4 itself because the inequality is strictly greater than (not greater than or equal to).
Select the measures of the angles of a triangle whose angles have measures in the ratio 6:8:10
Answer:
45, 60, 75
Step-by-step explanation:
The ratio of the angles are 6:8:10
Multiply by x to get the angle measures
6x, 8x,10x
We know the sum of the angles is 180 for a triangle
6x+8x+10x = 180
Combine like terms
24x = 180
Divide each side by 24
24x/24 = 180/24
x =7.5
Each angle is
6x = 6(7.5) =45
8x = 8(7.5) =60
10x = 10*7.5 = 75
The measures of the angles of the given triangle are 54 degrees, 72 degrees, and 90 degrees.
Explanation:To find the measures of the angles of a triangle whose angles have measures in the ratio 6:8:10, we can use the fact that the sum of the angles in a triangle is always 180 degrees. Since the ratio of the angles is 6:8:10, we can set up the equation 6x + 8x + 10x = 180, where x is a common factor. Solving this equation, we find that x = 9. Therefore, the measures of the angles are 6x = 54 degrees, 8x = 72 degrees, and 10x = 90 degrees.

(2)interest
Answer:
INTEREST just did it on odesseyStep-by-step explanation:
Answer:
If you do not pay the entire credit card bill, you are charged an interest on the unpaid part.
Step-by-step explanation:
If you do not pay the entire credit card bill, you are charged an interest on the unpaid part.
When you do not pay the entire bill or pay less than minimum or minimum amount, an interest is charged on the remaining balance.
The amount increases each month as the interest is added with the unpaid amount.
What is the future value of the 10% savings from earnings of $187.45 if it earns 5% annual interest, compounded monthly for 30 years? Use the compound interest formula to estimate the present value.
Answer:
$83.75
Step-by-step explanation:
To find the future value, we first need to define our variables.
P = 187.45 x 0.10 = 18.745
r = 5% or 0.05
t = 30 years
n = 12
Now we can use the formula:
[tex]A=P(1+\dfrac{r}{n})^{nt}[/tex]
[tex]A=18.745(1+\dfrac{0.05}{12})^{12(30)}[/tex]
[tex]A=18.745(1+\dfrac{0.05}{12})^{360}[/tex]
[tex]A=83.75[/tex]
So the future value after 30 years is $83.75.
The future value of the 10% savings from earnings of $187.45 is $83.75.
Future valuePrincipal= 187.45 x 0.10 = 18.745
rate = 5%
time = 30 years
n = 12
Hence:
Future value=18.745 (1+0.05/12)^30×12
Future value=18.745 (1.05/12)^360
Future value=$83.75
Inconclusion the future value of the 10% savings from earnings of $187.45 is $83.75.

Find the angle of elevation of the sun when a 24 foot tree casts a shadow of 36 feet
ANSWER
37°
EXPLANATION
The angle of elevation of the sun is the angle through which one has to raise the head to see the sun.
When a 24 feet tree casts a shadow of 36 feet, we can obtain a right triangle as shown in the diagram to help us calculate the angle of elevation of the sun.
Let x be the angle of elevation of the sun, then
[tex] \tan(x) = \frac{24}{36} [/tex]
[tex]x = \tan ^{ - 1} ( \frac{2}{3} ) = 37.433[/tex]
Hence, the angle of elevation of the sun is 37° to the nearest degree.

Olympic volleyball player Bev Oden averaged 3.42 "kills" (spikes that end a rally) per game. Predict her number of kills in a 5 game match.
Answer: 17.1
Step-by-step explanation:
If she averages 3.42 kills per game, she should average that for each of the 5 games. You need to multiply 3.42 times 5 for the total of 5 games.
3.42 x 5 = 17,1
Bev Oden, achieve approximately 17 kills in a 5 game match .
To predict the number of kills Bev Oden will achieve in a 5 game match, we can use her average kills per game to make the calculation.
Given that Bev Oden averages 3.42 kills per game, we simply multiply her average by the number of games in the match.
Step-by-step calculation:
Average kills per game: 3.42Number of games: 5Total kills = 3.42 kills/game x 5 games = 17.1 killsTherefore, Bev Oden is predicted to achieve approximately 17 kills in a 5 game match.

The students in Miss Collins class used a survey or’s measuring device to find the angle from their location to the top of a building they also measured the distance from the bottom of the building. the diagram shows the angle measure in the distance.
To the nearest foot, what is the height of the building?
A. 105ft
B. 116ft
C. 32ft
D. 54ft
(Image attached)
Answer:
A
Step-by-step explanation:
We can use trigonometric ratios to solve this.
With respect to the angle given, the building's height is the side that is "opposite".
Also, the given length of 63 feet is the "adjacent" side with respect to the angle given.
Which trigonometric ratio relates "opposite to adjacent" side?
It is TAN.
Now, let's write the ratio and solve for the height of the building (let h be height of the building). We have:
[tex]Tan(\theta)=\frac{Opposite}{Adjacent}\\Tan(59)=\frac{h}{63}\\h=Tan(59)*63\\h=104.85[/tex]
Rounding this, we get h = 105 feet, correct answer A
Answer:
The height of the building = 105 feet ⇒ answer (A)
Step-by-step explanation:
* To find the height of the building use the trigonometry functions
- Lets consider the height (h) of the building as a side of right angle triangle
and the other side is the distance from the bottom of the building
- Now we have right angle triangle one of its acute angle is 59°
- The length of one leg of the right angle = 63 feet
- We have the adjacent side of angle 59°
- we need to find the opposite side of angle (h)
∴ Lets use the function tan to find h
∵ tanФ = opposite to Ф/adjacent to Ф
∵ Ф = 59°
∵ The length of the side adjacent to Ф = 63 feet
∴ tan59 = h/63 ⇒ by using cross multiplication
∴ h = 63 × tan 59 = 104.849 ≅ 105 feet
∴ The height of the building = 105 feet answer (A)
Identify the equation of the translated graph in general form x^2-y^2=9 for T(-4,2)
Answer:
B
Step-by-step explanation:
If an equation of the form [tex]x^2-y^2=a[/tex] goes through a translation T (p,q), the transformed equation has the form [tex](x-p)^2-(y-q)^2=a[/tex]
Using this, we can write the equation given as:
[tex](x-(-4))^2-(y-2)^2=9\\(x+4)^2-(y-2)^2=9\\x^2+8x+16-y^2+4y-4-9=0\\x^2-y^2+8x+4y+3=0[/tex]
So, B is the right answer.
Answer:
b. [tex]x^2-y^2+8x+4y+3=0[/tex]
Step-by-step explanation:
The given hyperbola has equation [tex]x^2-y^2=9[/tex].
This hyperbola is centered at the origin.
If this hyperbola is translated, so that its center is now at (-4,2), its equation now becomes;
[tex](x+4)^2-(y-2)^2=9[/tex]
We now expand to obtain;
[tex]x^2+8x+16-(y^2-4y+4)=9[/tex]
[tex]\Rightarrow x^2+8x+16-y^2+4y-4-9=0[/tex]
[tex]\Rightarrow x^2-y^2+8x+4y-4-9+16=0[/tex]
The correct choice is B.
[tex]\Rightarrow x^2-y^2+8x+4y+3=0[/tex]

Use equations and inequalities to solve the following word problems.
3. Max is selling boxes of chocolate for a school fundraiser. He sold 12 boxes and earned $84. If all of the boxes have the same cost, how much does each box cost?
4. Anne donates at least $120 per month to charity. She has 4 favorite charities and divides her donations equally among them. How much does Anne donate to each of her favorite charities per month?
To find the cost of each box, we solve an equation: 12x = 84. To find the amount Anne donates to each charity, we set up an inequality: y ≥ 120/4.
Explanation:To solve the word problems, we can use equations or inequalities depending on the situation.
Question 3:
We are given that Max sold 12 boxes and earned $84. Let's assume the cost of each box is x dollars. The equation representing the given information is 12x = 84. To find the value of x, we divide both sides of the equation by 12: x = 84 / 12 = 7 dollars. Therefore, each box costs $7.
Question 4:
Anne donates at least $120 per month and divides her donations equally among 4 favorite charities. Let's assume the amount Anne donates to each charity is y dollars. The inequality representing the given information is y ≥ 120/4 = 30. Therefore, Anne donates at least $30 to each of her favorite charities per month.
