Answer:
prefixes
Step-by-step explanation:
The exact response will depend a lot on what you learned in your manual and the terms used in it, but the metric system is all based on the base of 10, like the numbers system you use every day.
Unlike the US/Imperial system where there's no clear relation between an inch, a yard and a mile for example, in the metric system everything is related by the factor 10 somehow.
The unit multiplier is also used as a prefix to identify measurements. Like for meter...
10 meters = 1 decameter
100 meters = 1 hectometer
1000 meters = 1 kilometer
and so on.

what is the y value when x equals 21? y=310-25(x)
Answer:
Step-by-step explanation:
You subtract 310 from 25 and get 285 then you multiply 285 x 21 and I believe that should solve this equation.
To find the value of 'y' when 'x' equals 21 in this equation, we substitute 21 for 'x', perform the multiplication 25*21 first, and then subtract this result from 310, yielding a 'y' value of -215.
Explanation:This question pertains to the mathematical equation y=310-25x. To find the value of 'y' when 'x' equals 21, we simply substitute 21 for 'x' in the equation. So, y = 310 - 25*(21). Multiplication happens first (due to the order of operations), yielding 525. When you subtract this from 310 (310-525), you get -215. Therefore, the value of 'y' when 'x' is 21 in this equation is -215.

the two lines y=2x+8 and y=2x-12 intersect at x-axis at P nad Q. work out the distance PQ
The x-coordinates of points P and Q, where lines y=2x+8 and y=2x-12 intersect the x-axis, are -4 and 6 respectively. Therefore, the distance between them, PQ, is 10 units.
Explanation:The two given lines are y = 2x + 8 and y = 2x - 12. These lines intersect the x-axis when y = 0. Setting y=0 in these two equations, we find the x co-ordinates of the intersection points P and Q.
For y = 2x + 8, solving 2x + 8 = 0 gives x = -4. Hence, Point P is at (-4,0).
Similarly, for y = 2x - 12, solving 2x - 12 = 0 gives x = 6. Hence, Point Q is at (6,0).
The distance PQ can then be calculated using the distance formula: "PQ = |Q - P| = |6 - (-4)| = 10 units".

How much more will $28,000 earn in interest than $16,000 if both are
invested in savings accounts with APYs of 5.8% for a year?
Answer:
Final answer is $12696.
Step-by-step explanation:
Given that initial amount P = $28000
Interest rate r = 5.8% = 0.058
Time = 1 year
Then future value is given by :
[tex]A=P\left(1+r\right)^t[/tex]
[tex]A=28000\left(1+0.058\right)^1=29624[/tex]
Similarly calculate future value for 2nd case:
Given that initial amount P = $16000
Interest rate r = 5.8% = 0.058
Time = 1 year
Then future value is given by :
[tex]A=P\left(1+\frac{r}{n}\right)^{n\left(t\right)}[/tex]
[tex]A=16000\left(1+0.058\right)^1=16928[/tex]
then difference = 29624 - 16928 = 12696
Hence final answer is $12696.
Answer:
$696.
Step-by-step explanation:
We are asked to find the amount of interest earned on $28,000 than $16,000 with APYs of 5.8% for a year.
We will use simple interest formula to solve our given problem.
[tex]I=Prt[/tex]
[tex]I[/tex] = Amount of interest,
P = Principal amount,
r = Interest rate in decimal form,
t = Time in years.
[tex]5.8\%=\frac{5.8}{100}=0.058[/tex]
Let us find difference of interests as:
[tex]\$28,000\times 0.058-\$16,000\times 0.058[/tex]
[tex](\$28,000-\$16,000)\times 0.058[/tex]
[tex](\$12,000)\times 0.058[/tex]

what is the value of [-4.6]
The value is:
-4
Step-by-step explanation:We are asked to find the value of the ceiling function: [tex]\left \lceil -4.6 \right \rceil[/tex]
As we know that the ceiling function always occupy the higher value in integers.
i.e. the ceiling function act as follows:
it takes value 0 when -1< x≤0
1 when 0 < x ≤ 1
2 when 1 < x ≤2
and so on.
As we know that:
-4.6 lie between -5 and -4.
Hence, we have:
[tex]\left \lceil -4.6 \right \rceil=-4[/tex]
Answer: -4
Step-by-step explanation:
The ceiling function (also known as the least integer function) is written as
[tex]f(x) = [x][/tex]
It gives the smallest integer greater than or equal to x .
For example : [5.6]=6
or [-1.9]= -1 [∵- 1 > -1.9 ]
To find : The value of [-4.6]
Clearly , [-4.6] is written in ceiling function notation.
Then, [-4.6] = smallest integer greater than or equal to -4.6
= -4 [∵ -4>-4.6]
Hence, the value of [-4.6] = -4

what is 25 1/2 × 5 –3 = 5 x
Answer:
249/10 = x, or x = 24.9
Step-by-step explanation:
25 1/2 × 5 –3 = 5 x should be written as 25 1/2 × 5 –3 = 5x
The goal here is to solve for x (you should state this specifically).
Start by multiplying 25 1/2 by 5, since we must multiply before addition or subtraction:
One way of doing this multiplication is to multiply 25 by 5 and then 1/2 by 5 and then summing up the results:
25×5 = 125, and 1/2 × 5 = 5/2, so the end result is:
125 + 5/2, or 125 + 2 1/2, or 127 1/2.
Next, subtract 3 from this result:
127 1/2 - 3 = 124 1/2
Then 124 1/2 = 5x. Solve for x. Converting 124 1/2 into an improper fraction:
249/2 = 5x. Dividing both sides by 5, we get:
249/10 = x, or x = 24.9

A real estate agent sells two sites for Rs. 18000 each. On one he gains 25% and on the other he loses 25 %. What is his loss or gain percent?
In this situation of selling two properties for the same price but with different gain and loss percentages, the real estate agent does not break even but incurs an overall loss of 6.25%.
Explanation:This is essentially a problem in profit and loss calculations in the domain of Mathematics. Since the selling price of both the sites is the same, the loss and gain percent will cancel out each other, resulting in no overall gain or loss. Here's why:
The real estate agent gains 25% on the first site. Hence, the cost price will be Rs. 18000 x 100/125 = Rs. 14400.The real estate agent loses 25% on the second site. Here, the cost price will be Rs. 18000 x 100/75 = Rs. 24000.The total cost price is Rs. 14400 + Rs. 24000 = Rs. 38400 and the total selling price is Rs. 18000 + Rs. 18000 = Rs. 36000. So, the real estate agent has incurred an overall loss. To find the percentage of loss, use the formula face: [(Loss) / (Cost Price)] * 100 = [(Rs. 38400 - Rs. 36000) / Rs. 38400] * 100 = 6.25% loss.

In year 13 the scientist will put tree wrap around tree 1 to protect it from the winter snow. The height of the tree wrap needs to be 45 inches the wrap is priced by the square foot. To the nearest square foot, how many square feet of wrap does she need
Answer:
22 feet²
Step-by-step explanation:
We are given:
height of tree h = 45 inches
Circumference= πd × inches
But d = 22.2inches
Therefore area will be
Area = 22.2π × 45 inches²
Area = 3137 inches²
Let's convert from inches² to feet², we have:
1 foot = 12 inches.
Therefore,
1 square foot = 1foot × 1foot = 12inches×12inches
= 3137inches² / 144 inches²
= 22feet²
Note: I attached missing data which states that diameter at year 13 is 22.2inches
To calculate the square footage of the tree wrap needed, we multiply the circumference of the tree trunk by the desired height. Assuming the tree trunk is cylindrical, we use the formula for the circumference of a circle: C = 2πr. Then, we convert the height to feet and calculate the square footage.
Explanation:To calculate the square footage of the tree wrap needed, we need to find the circumference of the tree trunk and multiply it by the desired height. Assuming the tree trunk is cylindrical, we can use the formula for the circumference of a circle: C = 2πr. We can then multiply the circumference by the desired height to get the square footage. Since we know the height is 45 inches, we need to convert it to feet by dividing by 12. Let's say the circumference of the tree trunk is 10 feet. The square footage of the tree wrap needed would be C * H = (2πr) * H = (2π * 5) * 3.75 = 47.12 square feet (rounded to the nearest square foot).

Answer:
Option C (Median: 347 and Mode: 347 and 348)
Step-by-step explanation:
Median is the middle point of the data and mode is the most repeated observation is the data. The first step involved in calculating the median it to list the observations in the ascending order. This gives:
335, 336, 337, 338, 339, 340, 347, 347, 348, 348, 356, 357, 358, 359
The second step is to identify the middle number (in case the observations are in odd numbers) or numbers (in case the observations are in even numbers) after the ascending order step has been done. It can be observed that the middle numbers in this data set are 347 and 347. Since there are two numbers, so their average will be the median of this data set. Therefore, the median is 347. It can be seen that maximum repetitions are 2 times for 347 and 348. So the mode is 347 and 348.
Therefore, Option C is the correct answer!!!
The correct option is c: Median: 347, Mode: 347 AND 348. This is determined by sorting the numbers and finding that 347 is the median and both 347 and 348 are the modes.
This question involves identifying measures of central tendency, specifically the median and the mode, from a list of numbers.
Option a: Median: 359, Mode: 358Option b: Median: 340, Mode: 350Option c: Median: 347, Mode: 347 AND 348Option d: Median: 358, Mode: 348To determine the correct answer, we proceed step-by-step to calculate the median and mode from the provided sequence: 359, 357, 348, 347, 337, 347, 340, 335, 338, 348, 339, 356, 336, 358.
Step 1: Sorting the List
The sorted list is: 335, 336, 337, 338, 339, 340, 347, 347, 348, 348, 356, 357, 358, 359
Step 2: Finding the Median
The median is the middle value of a sorted list. For a list of 14 numbers, it is the average of the 7th and 8th values:
Median = (347 + 347) / 2 = 347
Step 3: Finding the Mode
The mode is the number that appears most frequently. Here, 347 and 348 each appear twice.
Mode = 347 and 348
Based on these calculations, the correct option is Option c: Median: 347, Mode: 347 AND 348.

In geometry, what’s the difference between a postulate and a theorem? Give an example of each
Answer:
Step-by-step explanation:
This is a course specific question. What I think is a postulate may not be listed in your lesson. A postulate is a statement that is assumed to be true. There has not been an exception found in over 2000 years. A postulate does not require proof: its truth is accepted.
Example: Two points on the same plane have exactly 1 line that can go through them.
Theorem: using the postulates to begin with, a theorem is a statement that can (and should) be proved.
Example: Two lines that are on the same plane, if they intersect at all, intersect only once.
a^2 + b^2 = c^2
This well known theorem can be proved well over 100 ways.
In geometry, a postulate is an accepted statement without proof that serves as a fundamental assumption, while a theorem is a proven statement based on previously established postulates, theorems, and definitions.
An example of a postulate is the "Parallel Postulate," and an example of a theorem is the "Pythagorean Theorem."
To find the difference between a postulate and a theorem
Now,
A postulate is a statement that is accepted without proof and serves as a fundamental assumption. It provides the basis for building geometric reasoning.
An example of a postulate is the "Parallel Postulate," which states that if a line intersects two other lines forming congruent alternate interior angles, then the two lines are parallel.
On the other hand, a theorem is a statement that has been proven based on previously established postulates, theorems, and definitions.
An example of a theorem is the "Pythagorean Theorem," which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
So, while postulates are accepted as true without proof, theorems are derived from logical deductions and require proof.

Cramer's rule says that given a system of equations of two variables x and y then:
[tex]x =\frac{Det(A_X)}{Det(A)}[/tex]
[tex]y =\frac{Det(A_Y)}{Det(A)}[/tex]
For this problem we know that:
[tex]Det(A) = |A|=\left|\begin{array}{ccc}4&-6\\8&-2\\\end{array}\right|[/tex]
Solving we have:
[tex]|A|= 4*(-2) -(-6)*8\\\\|A|=40[/tex]
[tex]Det(A_X) = |A_X|=\left|\begin{array}{ccc}38&-6\\26&-2\\\end{array}\right|[/tex]
Solving we have:

[tex]Det(A_Y) = |A_Y|=\left|\begin{array}{ccc}4&38\\8&26\\\end{array}\right|[/tex]
Solving we have:
