So say we have the number: 54,321
The 5 would be worth 50,000 meaning it's in the ten thousands place.
The 4 would be worth 4,000 meaning it's in the thousands place.
.
The difference between them is a zero, so the ten thousands place is 10 times bigger than the thousands place

Suppose that y is directly proportional to x, and y = 150 when x = 15. What is the constant of proportionality?
Answer: The required constant of proportionality is 10.
Step-by-step explanation: Given that y is directly proportional to x, and y = 150 when x = 15.
We are to find the constant of proportionality.
According to the given information, we can write
[tex]y\propto x\\\\\Rightarrow y=kx~~~~~~~~~~~~~~~~[\textup{where k is the constsnt of propotionality}].[/tex]
When y = 150 and x = 15, we get from the above equation that

Step-by-step explanation:
(a) A dog owner records the weight of her dog. She finds that from the age of 20 weeks to the age of 48 weeks, the dog’s weight can be modelled by the equation w = 0.92t−0.15 (20 ≤ t ≤ 48), where w is the weight of the dog in kilograms, and t is the age in weeks.
(i) Find the weight of the dog at age 26 weeks according to this model.
(ii) Explain the inequality (20 ≤ t ≤ 48) that follows the equation.
(iii) Using algebra, calculate the age at which the dog’s weight is 40kg
(iv) Write down the gradient of the straight line represented by the equation w = 0.92t−0.15. What does this measure in the practical situation being modelled? (v) Either using Graphplotter or by hand, sketch the graph of w = 0.92t−0.15, putting w on the vertical axis and covering the time interval 20 ≤ t ≤ 48.
(vi) Explain why the model cannot be extended to model accurately the dog’s weight at birth
Answer:
(i)23.77kg
(ii)(ii) the inequality 20≤t≤48 means the weight of the dogs determined is for dogs that have the age of 20 weeks or less to the age of 48 weeks not more.
(iii)44 weeks
(iv)0.92
(v)Attached
(vi)The value of weight will be negative,which is unrealistic.
Step-by-step explanation:
(i)Given that the weight is modeled by the equation;
w = 0.92t−0.15 (20 ≤ t ≤ 48)
then substitute the value of t in the equation given that t=26 weeks
w=0.92*26-0.15=23.77kg
(ii) the inequality 20≤t≤48 means the weight of the dogs determined is for dogs that have the age of 20 weeks or less to the age of 48 weeks not more.
(iii)Apply the equation for weight
w=0.92t-0.15
40=0.92t-0.15
40+0.15=0.92t
40.15=0.92t
40.15/0.92=t
43.6⇒⇒44 weeks
(iv) Here , write the equation in slope intercept form of y=mx+c where m is the slope and c is the y-intercept
w=0.92t-0.15
y=mx+c
m=0.92
(v)sketch attached
(vi)
At birth, t=0 hence to find weight
w=0.92t-0.15
w=0.92*0-0.15
w=0-0.15
w=-0.15
The model cannot be extended to model accurately the dog's weight at birth because you will get a negative value for weight which is not realistic.
Solve the inequality 3 ≥ t + 1 Question 12 options: a) {t | t ≤ 4} b) {t | t ≤ 2} c) {t | t ≥ 2} d) {t | t ≥ 4}
Answer: b
Step-by-step explanation:
ok, lets see the answers one for one.
a) in this case, t can be 4, if t= 4 then t + 1 = 5 and the inequality is false.
b) in this case, the maximum vale of t is 2, then 2 + 1 = 3, the inequality is true here, and all the other numbers in the set is smaller than 2, then all this set keeps the inequality true.
c and d) both sets allow to take, for example, t= 10, wich makes the inequality false.
now in this type of exercises, you should se the biggest and lowest number that keeps the inequality true, in this case the biggest is 2, because 2 + 1 = 3, and there is no lowest limit because any negative number + 1 will be less than 3. With those limits then you can figure the set of valid solutions with all the numbers in between.
Final answer:
The solution to the inequality 3 ">=" t + 1 is option b) {t | t ">=" 2}, which means that t is any number less than or equal to 2.
Explanation:
Before solving the inequality 3 ">=" t + 1, first, let's isolate the variable t. To do that, we subtract 1 from both sides of the inequality:
3 - 1 ">=" t + 1 - 1
2 ">=" t
This can be read as 't is less than or equal to 2' or 't must be any number that is 2 or smaller.' Therefore, the correct answer is:
{t | t ">=" 2}
When comparing with the question options, it is clear that option b) matches our solution.
Thus, option b) {t | t ">=" 2} is the correct answer to the inequality given in the question.

Write each expression in exponential form 2 x 2 x 2 x 2 =
Step-by-step explanation: Exponential form contains a base and an exponent. The base is the number that is multiplied so in this case, 2 is the base. Next we write the exponent which is the number of times that the base is multiplied. Since 2 is multiplied 4 times, the exponent is 4.
So in exponential form, 2 x 2 x 2 x 2 can be written as [tex]2^{4}[/tex].
The expression 2 x 2 x 2 x 2 can be written in exponential form as [tex]2^{4}[/tex]
What is Exponential form?In a variety of mathematical applications, such as scientific notation, computations using powers, and illustrating development or decay processes, exponential form is frequently used. A base and an exponent are both present in exponential form. The multiplied number, in this example 2, is known as the base. The exponent, which represents the number of times the base has been multiplied, is then written. The exponent is 4 since 2 has been multiplied 4 times.
Then we can see that there are four 2s then we can write in exponential as 2 x 2 x 2 x 2 =[tex]2^{4}[/tex]

If a triangle has side lengths 4, 5, and 6 units, then its
area is 10 square units.
OC)
Answer:
If a triangle has side lengths 3, 4, and 5 units, then its area is 6
Step-by-step explanation:
Deductive reasoning represents an important form of logical reasoning in which a conclusion is based on the concordance of multiple premises that are generally assumed to be true
we have
If a triangle has side lengths 3, 4, and 5 units, then its area is 6
we know that
1) If triangle has side lengths 3, 4 and 5, then is a right triangle because satisfy the Pythagoras Theorem
2) All right triangles have an area equal to one half the product of the two smaller side lengths
[tex]A=\frac{1}{2}(a)(b)[/tex]
substitute the values
[tex]A=\frac{1}{2}(3)(4)[/tex]
[tex]A=6\ units^2[/tex]
therefore
The statement is valid based on deductive reasoning
Final answer:
A valid statement derived from deductive reasoning is that a right triangle with side lengths of 3, 4, and 5 units has an area of 6 square units. This is consistent with the properties of right triangles and the formula for the area of a triangle.
Explanation:
Based on deductive reasoning and the properties of right triangles, we can make a valid statement regarding the triangle with side lengths of 3, 4, and 5 units. Since the sum of the squares of the two smaller sides (3² + 4²) equals the square of the longest side (5²), by the Pythagorean theorem, this is a right triangle. Additionally, the area of a right triangle is given by A = (base × height) / 2, therefore, if we take the two shorter sides as the base and height, the area of this triangle would be (3 × 4) / 2 = 6 square units.
The valid statement based on the given information is that if a triangle has side lengths 3, 4, and 5 units, then its area is 6 square units. The other statements about polygons, perimeters, and other triangles' side lengths are not necessarily valid based on the given information alone.

Answer:
Step-by-step explanation:
Ok so supplementary angles add up to 180°. If A and B add up to 180, then they can be added together to be solved. x+2x-30=180 would be your equation. From here you must balance the variable values on one side and numerical values on the other side. This can simply be done by adding 30 to both sides. Not the -30 is gone but 180 increased by 30 degrees to 210. next, combine like terms on the x side to get 3x. (2x+x=3x). set 3x equal to 210 and divide both sides to lose the 3 in front of the x value. 210/3 is equal to 70, making x=70! This may be hard to follow, so comment below if you need a broader explanation. Have good day!

Write the equation of the line perpendicular to y= 2x +1 that passes through the point (6,2)
Answer:
Step-by-step explanation:
Hello:
the equation is : y = ax+b
the slope is a : a×(2) = -1......( perpendicular to a line with a slope of 2 for : y=2x+1)
a =-1/2 y=(-1/2)x+b
the line that passes through (6, 2) : 2 = (-1/2)(6)+b
b = 5
the equation is : y = (-1/2)x+5
You can use the fact that perpendicular lines have slopes such that their multiplication ends up as -1.
The equation of the line perpendicular to line y = 2x + 1 and passing through (6,2) point coordinate is given as
[tex]y = -\dfrac{1}{2}x + 5[/tex]
What is the slope of perpendicular lines?Suppose that first straight line has slope 's'
Let another straight line be perpendicular to this first line.
Let its slope be 'a'
Then due to them being perpendicular, they have their slopes' multiplication as -1
or
[tex]s \times a = -1\\\\a = -\dfrac{1}{s}[/tex]
How to get the slope intercept form of a straight line equation?If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:
[tex]y = mx + c[/tex]
The first line y = 2x + 1 is in slope intercept form and its slope is s = 2
Now, let the second line which is perpendicular to this line and passing through (6,2) coordinate be
y = [tex]ax + b[/tex]
Then as both lines are perpendicular, thus
[tex]a = -\dfrac{1}{s} = -\dfrac{1}{2}[/tex]
Thus, equation of second line is
[tex]y = -\dfrac{1}{2}x + c[/tex]
Since this line passes through coordinate (6,2), thus, this point coordinate should satisfy the equation of line as an equation is true for all points the graph represented by it passes through.
Thus,
[tex]y = -\dfrac{1}{2}x + c[/tex]
[tex]2 = -\dfrac{1}{2} \times 6 + c\\\\2 = -3 +c\\\\c=2+3 = 5[/tex]
Thus, equation of the second line is
[tex]y = -\dfrac{1}{2}x + 5[/tex]
Thus,
The equation of the line perpendicular to line y = 2x + 1 and passing through (6,2) point coordinate is given as
[tex]y = -\dfrac{1}{2}x + 5[/tex]
