Final answer:
The number that best represents a positive charge of 1,350 is B. 1,350. Positive charges are indicated by numbers without a negative sign and the magnitude of charge is always represented as a positive value.
Explanation:
The number that best represents a positive charge of 1,350 is B. 1,350. Positive charges are indicated by numbers without a negative sign. As the question specifies a positive charge, the correct choice is the one without a minus in front of the number, therefore, option B is correct. This choice directly corresponds with the charge being positive, as indicated in the options provided.
It is important to note that the magnitude of charge is independent of its type, meaning that the numerical value of a charge represents its magnitude and is always positive, irrespective of whether the charge itself is positive or negative. An example in physics would be the charge of an electron which is -1.602 × 10-19 C, whereas a proton has a charge of +1.602 × 10-19 C, both having the same magnitude of charge but different signs.
Katelynn bought a used car and it was 5 years old. She purchased it for 10,250, after two years the Kelly Blue book value for her car is $8,075. Determine how much the car was worth when it was first bought by the original owners and determine what the depreciation rate is. Hint: Remember these are exponential equations of the form y=abx.
Answer:
a) rate of depreciation is 11.24%
b) original price of car = $18605.33
Step-by-step explanation:
The formula to apply is;
current price= original price *(1-r)^n where r is the rate of depreciation as a decimal and n is the time period
a) Find the rate of depreciation given that ;
The car was bought at $10,250 when it was 5 years old
After 2 years, the value was $8,075
Apply the formula ;
current price= original price *(1-r)^n
8,075=10,250* (1-r)²
8,075/10250 = (1-r)²
0.78780487804 =(1-r)²
√0.78780487804 =(1-r)
0.88758373016 = 1-r
r=1-0.88758373016
r=0.11241626983 ⇒ 11.24%
b) When the car was first bought, the price was;
Apply the formula;
current price= original price *(1-r)^n
10,250 =original price * (1-0.1124)⁵
10,250=O.P *(0.5509)
10,250/0.5509 = original price
$18605.33= original price
What is 3 divided by 0.05?
3 divided by 0.05 is equal to 60.
Given that we need to find the value of 3 divided by 0.05,
To calculate 3 divided by 0.05, you can use the following formula:
3 ÷ 0.05 = [tex]\frac{3}{0.05}[/tex]
To divide by a decimal number like 0.05, you can multiply both the numerator and denominator by a power of 10 to eliminate the decimal point.
In this case, multiplying by 100 will work:
[tex]3 \div 0.05 = \frac{3}{0.05} \times\frac{100}{100}[/tex]
Now we can perform the division:
[tex]3 \div 0.05 = \frac{3\times 100}{0.05 \times100}[/tex]
Simplifying further:
[tex]3 \div 100 =[/tex] [tex]\frac{300}{5}[/tex]
Finally, performing the division:
300 / 5 = 60
Therefore, 3 divided by 0.05 is equal to 60.

John and Tyrone each go for a morning jog before work. John's jogging
pace is represented by the equation y=5x, where y is the number of
miles he jogs and x is the number of hours he jogs. Tyrone's pace is
given by the graph. Choose the statement that correctly compares their
unit rates.
The question asks to compare the unit rates of two joggers, John and Tyrone. John's unit rate is 5 miles per hour, as indicated by the equation y=5x. Without Tyrone's graph data, a direct comparison cannot be made.
Explanation:The subject of the question involves comparing unit rates of two joggers, which requires an understanding of linear equations and graph interpretations in mathematics. Based on the given information, John's jogging pace is defined by the linear equation y=5x, where y is the number of miles he jogs and x is the number of hours he jogs. This equation suggests that John's unit rate, or his speed, is 5 miles per hour. However, to compare John's unit rate to Tyrone's, we need additional information about the slope of Tyrone's graph, which represents his speed.
Without the specific graph or a defined equation for Tyrone's pace, we can't make a direct comparison. Typically, the unit rate for a jogger is found by taking the slope of the position vs. time graph, which involves dividing the change in position (the rise) by the change in time (the run). If the slope of Tyrone's graph were provided, we could determine his speed and compare it to John's.
Remember, the unit rate is a measure of how much of something occurs per unit of another thing. In this case, it's the speed at which each jogger moves per hour. If additional data from Tyrone's graph were given, we would look for a constant rate of change or identify two points on the graph to calculate the slope (speed) and thus compare the unit rates of the two joggers.

What is the name of the relationship between 1 and 4?
Two horizontal parallel lines cut by a diagonal transversal. Angles 1 and 3 are on the left-hand side of the transversal and the interior of the parallel lines. Angles 2 and 4 are on the right-hand side of the transversal and the interior of the parallel lines.
Answer:
Angles 1 & 4 are alternate interior angles.
The correct name for the relationship between angles 1 and 4 in the given scenario is that they are corresponding angles.
When two parallel lines are cut by a transversal, the following relationships exist between the angles formed:
1. Corresponding angles are equal. These are the angles that are in the same relative position at each intersection where a straight line crosses two others. In this case, angle 1 corresponds to angle 4 because they are both above the parallel lines and on the same side of the transversal.
2. Alternate interior angles are equal. These are the angles that are inside the parallel lines and on opposite sides of the transversal. Angle 3 would be the alternate interior angle to angle 1, not angle 4.
3. Alternate exterior angles are equal. These are the angles that are outside the parallel lines and on opposite sides of the transversal.
4. Consecutive interior angles (also known as same-side interior angles) are supplementary. These are the angles that are on the same side of the transversal and inside the parallel lines.
Since angle 1 and angle 4 are in the same relative position at each intersection (both are above the parallel lines and on the same side of the transversal), they are corresponding angles. Therefore, if the lines are parallel, angle 1 is equal to angle 4.

3.24 with the digit 4 repeating can be converted into the simplified fraction ⅔, which is equivalent to 3 ½.
Explanation:
The student is asking how to express the decimal 3.24 with the digit 4 repeating as a simplified fraction. The repeating decimal can be represented as 3.244444... or 3.24 bar.
To convert this repeating decimal to a fraction, we first denote x = 3.24. To eliminate the repeating part, we can multiply x by 100 to shift the decimal two places to the right, getting 100x = 324.44. Then, we subtract the original equation from this new equation (100x - x) to remove the repeating decimal. This results in 99x = 321, which simplifies to x = ⅔ or x = 3 ½ in fraction form. Therefore, 3.24 bar as a simplified fraction is ⅔.

a) The value of x as calculated in the image is 45 degrees.
b) For the lines AD and BC to be parallel in a quadrilateral, the opposite angles need to be supplementary (i.e., their sum should be 180 degrees).
In this case, angle A is:

and angle D is:
3x = 345 = 135 degrees.
Since 90 + 135 = 225 degrees, which is not equal to 180 degrees, the lines AD and BC would not be parallel when ABCD is drawn to scale.

A number cube is rolled three times. What is the probability of rolling a number less than 3 each time?
Answer:
8/27
Step-by-step explanation:
The probability of rolling a number less than 3 three times in a row on a number cube (or die) is 1/27.
Explanation:The subject of this question is probability in mathematics. A number cube, often referred to as a die, has six faces numbered 1 through 6. If we are looking for the probability of rolling a number less than 3, we are looking for the probability of rolling a 1 or a 2. Out of six possibilities, two are successful outcomes (1 and 2), so the probability of rolling a number less than 3 in one roll is 2 out of 6, or 1/3.
However, since the number cube is rolled three times, we have to consider this probability for each roll. In probability, when we want to find the likelihood of multiple events all occurring, we multiply the probabilities of each individual event. Therefore, the probability of rolling a number less than 3 three times in a row is (1/3) * (1/3) * (1/3) = 1/27.

Answer:
sin θ = 5/13
cos θ = 12/13
Step-by-step explanation:
We know that tan θ = 5/12 which indicates that the adjacent side relative to θ is 12 and the opposite side relative to θ is 5. The hypotenuse is missing which can be figured out using the Pythagorean Theorem.
a² + b² = c²
c = √(5² + 12²)
c = √(169)
c = 13
The hypotenuse is 13, and we know that the opposite and adjacent sides measure 5 and 12, respectively.
sin θ = opposite/hypotenuse
sin θ = 5/13
cos θ = adjacent/hypotenuse
cos θ = 12/13

Suppose chocolate costs $17.60 per kilogram. Karega buys 25 grams of chocolate and Samadhi buys 100 grams of chocolate.
How much more did Samadhi pay for her chocolate?
$0.44
$1.32
$2.20
$2.64
Samadhi paid $1.32 more than Karega for her chocolate.
Explanation:The subject of this question is in Mathematics, specifically it involves unit conversion and arithmetic calculations. We know that chocolate costs $17.60 per kilogram. But Karega and Samadhi are buying chocolate in grams which means we need to convert the cost from kilograms to grams. 1 kilogram is equal to 1000 grams. So, cost of chocolate per gram = $17.60/1000 = $0.0176.
Karega is buying 25 grams of chocolate, so the cost = 25 * $0.0176 = $0.44. Samadhi is buying 100 grams of chocolate, so the cost =$0.0176 * 100 = $1.76. To find out how much more Samadhi paid for her chocolate compared to Karega, we subtract Karega's cost from Samadhi's cost which gives $1.76 - $0.44 = $1.32.

How much does it cost Anouk to fill both of her dispensers with hand soap?
Enter your answer in the box.
Answer:
$4.75
Step-by-step explanation:
1milliliter = 1mL = 1.0*10^-3L
50mL = 50*10^-3L = 0.05L.
But 0.05L costs $0.19 to refill,
How much will 1.25L cost?
0.05L = 0.19
1.25 = x
X = (1.25*0.19) / 0.05
X = $4.75
It will cost her $4.75 to refill 1.25L of soap
Answer:
$9.5
Step-by-step explanation:
Each dispenser holds 1.25 liters, so we have a total of 1.25*2 = 2.5 liters to be filled.
Each 50 milliliters of soap, that is, 0.05 liters, costs $0.19, so we can solve now using a rule of three:
0.05 liters of soap -> $0.19
2.5 liters of soap -> X
0.05/2.5 = 0.19/X
X = 2.5*0.19/0.05 = $9.5
It will cost $9.5 to fill both dispensers with soap.
