Answer:
21 hours
Step-by-step explanation:
After 2 hours the temperature has risen to 7°f
The time taken to rise to an additional 13°f can be calculated as follows
1 hour takes 3.5°f
13°f = 3.5×6
= 21 hours
Hence it would take 21 hours

8(2x + 3) = PxQ
A. ¿Para cuáles valores de PyQ la ecuación tiene una infinidad de soluciones?
B. ¿Para cuáles valores de PyQ la ecuación no tiene solución?
Recuerda contestar todas las partes de la pregunta en el espacio provisto.
Respuesta:
P = 16; Q = 24
P = 0; Q = 0
Explicación paso a paso:
Dada la relación:
8 (2x + 3) = Px + Q
Abra el soporte
16x + 24 = Px + Q
Los valores de P y Q para los que la ecuación tiene infinidad de solución:
Px = 16x
Q = 24
Por tanto, en P = 16; Q = 24, la ecuación tiene infinidad de soluciones.
Valores de P y Q para los que la ecuación no tiene solución:
Px = 0; P = 0
Q = 0
Por tanto, los valores de P y Q para los que la ecuación no tiene solución es 0

Answer:
points (8, 0) and (3, 0)
Step-by-step explanation:
Here we're being asked to find the roots of this quadratic equation.
Set f(x) = 3(x² - 11x + 24 = 0.
This factors into f(x) = 3(x - 8)(x - 3) = 0.
Then x - 8 = 0 and x - 3 = 0, yielding x = 8 and x = 3. These correspond to the points (8, 0) and (3, 0).
Carlos deposits $250 into a savings account that earns 4% interest added to it annually. How much interest is added at the end of the year?
The O’Neill Raiders fundraiser has raised $700, which is 28% of their total fundraising goal. What is their total goal?
Sameer scored better than 78% of all students taking a standardized exam. If 650 students took the exam, how many did Sameer score better than?
The interest added at the end of the year is $10, The total goal of O’Neill Raiders fundraiser is $2500 and Sameer scored better than 507 students.
What is Percentage?Percentage is the parts of a number per fraction of 100. We can divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Initial amount, P = $250
Rate of interest, r = 4% = 0.04
Interest amount = P × r × t, where t is the number of years = 1 here.
= 250 × 0.04 × 1
= $10
28% of the total fundraising goal = $700
Let x be the total fundraising goal.
28% × x = 700
0.28x = 700
x = 700 / 0.28 = $2500
Total number of students = 650
Sameer scored better than 78% of all students.
Number of students that Sameer scored better = 78% × 650
= 0.78 × 650
= 507
Hence all the answers are found.

claire makes a bracelet using blue and red beads. each bracelet has 20 red beads and 5 blue beads. write an ordered pair to represent the number of red beads and blue beads claire will use to make 8 bracelets. (if u even try leaving a link, i’m reporting u) pls help btw i’m in need of help immediately!)
Answer: (20, 5) or (5, 20)
Explanation: An ordered pair is made up of a set of numbers, one number for each dimension, contained in a set of parenthesis and separated by commas. In this problem, there are two dimension; red beads and blue beads. The ordered pair is comprised of the number of red beads (20) and the number of blue beads (5). Following the format previously described we get the answer (20, 5). You can also write (5, 20) since neither number depends on the other.

Emma has a board 5 feet long and cuts it into 6 equal pieces how long in feet is eacgpeace if the board in a fraction
Answer:
Imagine an easier version of this problem: You have a board 5 feet long that you must cut (divide, right?) into two equal parts. It is probably clear to you that you simply divide the length (5) by the number of parts you're dividing it into (2) to obtain the length of each piece (2.5 feet).
Use the same method for your problem 5 feet divided by 6 is 0.83 feet per piece.
We do not ordinarily divide feet into decimal portions, but instead into inches. Since an inch is 1/12 of a foot, you could simply say 5/6 = how many twelfths? or 5/6 = n/12 Solve this by inspection or by cross multiplying 5 times 12 equals n times 6. So n must equal 10, and your pieces of board are each 10 inches long.
Which graph does not represent a function
Answer:
The graph that does not represent a function is;
The first graph of the circle
Step-by-step explanation:
A function is a relationship, rule or law that maps the inputs 'x' the input set 'X' known as the domain, to exactly one output 'y' in the output set 'Y' known as the range
Therefore, a function maps an input to exactly one output
In a graph, the inputs are usually the x-variables, therefore the graph that maps the x-variables (in which an x-variable has) to more than one y-variable is the graph of the circle
In the graph of the circle, we have;
When x = 0 at the origin, y = 0
Similarly
When x = 0 at the maximum point, y = 4
Therefore, the graph of the circle does not represent a function.

If Sin A = .3642, find the measure of Angle A to the nearest degree.
Answer:
the measure of angle A to the nearest degree is 36°
The measure of angle A to the nearest degree is 21°.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
We can use the inverse sine function (denoted as sin⁻¹ or arcsin) to find the measure of angle A:
sin A = 0.3642
Taking the inverse sine of both sides, we get:
A = sin⁻¹(0.3642)
Using a calculator, we get:
A ≈ 21.3°
Rounding to the nearest degree, we get:
A ≈ 21°
Therefore,
The measure of angle A to the nearest degree is 21°.
