There are 1,525 pages in a book. Julia and Kim round the number of pages to the nearest hundred. Julia says it is one thousand, five hundred. Kim says it is 15 hundreds. Who is correct? Explain your thinking.
Answer:
They are both correct.
Step-by-step explanation:
SInce they both are saying the same amount of pages just in different ways, Kim is saying a thousand plus five hundred, that is 1500, and Kim says 15 hundred, which is basically 1500, so they are both rounding up the number to the nearest cent correctly just are expressing the number in different ways.
factor the expression 10x+40
Final answer:
To factor the expression 10x + 40, we can factor out the greatest common factor (GCF) of 10 from both terms, resulting in 10(x + 4).
Explanation:
To factor the expression 10x + 40, we can first find the common factor for both terms, which is 10. Factoring out 10, we get 10(x + 4). This expression represents the original 10x + 40. In simpler terms, we've taken out the common factor of 10 from both terms, leaving us with 10 multiplied by the quantity (x + 4). This factored form is useful for simplifying expressions or solving equations. Essentially, factoring helps us break down a more complex expression into simpler parts, making it easier to work with and understand in various mathematical contexts.
kenneth earns a commission of 4 1/2 on total sales plus a weekly salary of $350. What is his gross pay if his sales are 4500 this week?
Answer:
gross pay = $552.50
Step-by-step explanation:
Kenneth earns a commission on his total sales = [tex]4\frac{1}{2}[/tex] %
= [tex]\frac{9}{2}[/tex] %
= 4.5%
If his sales are 4500 this week.
His commission would be = 4.5% × 4500
= [tex]\frac{4.5}{100}\times 4500[/tex]

Given: mTRV = 60° mTRS = (4x)° Prove: x = 30 What is the missing reason in step 3? substitution property of equality angle addition postulate subtraction property of equality addition property of equality
Answer: Angle addition postulate.
Explanation: If [tex]\angle TRV= 60^{\circ}[/tex] and [tex]\angle TRS=4x^{\circ}[/tex]
here, if we have to prove x=30
If there is a condition that TR is a line which meets with the line segment VS at point R then by the Angle addition postulate, we can say that [tex]\angle TRV+\angle TRS=180^{\circ}[/tex]⇒[tex]x=30^{\circ}[/tex]
But,
In option (1) substitution property of equality
If there is condition that [tex]\angle TRV=\angle TRS[/tex]
then we can use substitution property of equality,
And, in this case [tex]4x^{\circ}=60^{\circ}[/tex]⇒[tex]x=15^{\circ}[/tex]
which is wrong. So, we can not use this property here.
In option (3) subtraction property of equality
There is no use of this property to find the value x.
In option (4) addition property of equality
There is no use of this property to find the value x.
The omitted reason in step 3 should be the angle addition postulate.
According to the angle addition postulate , the value or measurement of an angle is the sum of all the angles which makes up that segment.From the diagram attached ;
mTRV = 60 ; ∠TRS = 4x
According to the addition postulate :
mTRV + ∠TRS = 180° (sum of linear pair of angles).
Though obtaining the value of the missing angle required substituting 30 for the value of x. However, it is because of the addition postulate which gives the sum of a linear pair of angles that we were able to establish that mTRV + ∠TRS = 180°.Hence, the missing reason for the third step is the angle addition postulate.

Dustin is 11 years younger than elias. In two years, Dustin will be half as old as elias. How old is Dustin
Final answer:
Dustin is currently 9 years old.
Explanation:
The question is asking us to solve for Dustin's current age given a relationship between his age and Elias's. To solve the problem, we need to set up an equation where Dustin's current age is represented by D and Elias's current age is represented by E.
We are told that Dustin is 11 years younger than Elias, which gives us the first equation:
E = D + 11
In two years, Dustin will be half as old as Elias. We can represent this future scenario with another equation:
D + 2 = (E + 2) / 2
To find Dustin's age, we will solve these two equations simultaneously. By substituting the expression for E from the first equation into the second equation, we get:
D + 2 = (D + 11 + 2) / 2
The equation simplifies to:
D + 2 = (D + 13) / 2
Now, we simplify and solve for D:
Multiply both sides of the equation by 2 to eliminate the fraction: 2(D + 2) = D + 13Distribute and simplify: 2D + 4 = D + 13Subtract D from both sides: D + 4 = 13Finally, subtract 4 from both sides to find D: D = 9Therefore, Dustin is currently 9 years old.

How many ternary (0, 1, 2) sequences of length 10 are there without any pair of consecutive digits the same?
There are 10 spaces then the first space will be (3,1), the second one cannot be the same as the first one so it will have to be (2,1).
So it will come down to 3×2^9
There are 1536 ternary sequences of length 10 with no pair of consecutive digits the same.
Explanation:The question is asking about how many ternary sequences of length 10 there can be without any pair of consecutive digits being the same. In a sequence of length 10, each digit has 3 possible values (0, 1, 2) but cannot be the same as the digit before it. Therefore, the first digit has 3 choices, and each subsequent digit has 2 choices (since it can't be the same as the previous one). Using the multiplication principle of counting, there would be 3*2^9 = 1536 such sequences.

A tank and a pail contain a total of 5136 milliliter of water. Jacob pours 314 milliliters of water from the pail into tank. The amount of water in the tank is now 7 times what is left in the pail. How much water was in the pail at first?
To find the initial amount of water in the pail, set up a system of equations based on the total volume and the information provided after transferring some water. Solve the equations to obtain the initial quantity of 957 milliliters in the pail.
Explanation:A student posed a problem: A tank and a pail contain a total of 5136 milliliters of water. Jacob pours 314 milliliters of water from the pail into the tank. The amount of water in the tank is now 7 times what is left in the pail. How much water was in the pail at first?
Let's denote the initial amount of water in the tank as T milliliters and in the pail as P milliliters. According to the given information, the combined quantity of water in both is 5136 milliliters:
T + P = 5136After transferring 314 milliliters from the pail to the tank, the tank now has T + 314 milliliters, and the pail has P - 314 milliliters. It is also given that the water in the tank is now 7 times the water left in the pail:
(T + 314) = 7*(P - 314)Now, we have a system of two equations:
By solving these equations, we can find the initial amount of water in the pail, P. First, modify the second equation to isolate T:
T = 7P - 2206 - 314T = 7P - 2520Next, substitute the expression for T from the second equation into the first equation and solve for P:
7P - 2520 + P = 51368P = 5136 + 25208P = 7656P = 7656 / 8P = 957 millilitersInitially, there were 957 milliliters of water in the pail.

Ambrose has an indifference curve with equation x2= 20 − 4 x 1/21. when ambrose is consuming the bundle (4, 16), his marginal rate of substitution is 25/4.
An indifference curve is used in economics to show different combinations of goods that provide equal satisfaction to a consumer. Ambrose's indifference curve equation and marginal rate of substitution are given, representing his willingness to trade one good for another while holding utility constant.
Explanation:An indifference curve is a graphical representation used in economics to show the different combinations of two goods that provide equal satisfaction or utility to a consumer. In this case, Ambrose has an indifference curve with the equation x2 = 20 - 4x1/21. To find his marginal rate of substitution (MRS), we need to calculate the slope of the indifference curve at the point (4, 16). The MRS is given as 25/4, which means that Ambrose is willing to give up 25/4 units of x1 in exchange for 1 unit of x2, while keeping his utility constant.

when a decimal is written in word form,what indicates that the equivalent form is a mixed number and not a fraction
Final answer:
A decimal written in word form represents a mixed number if there's a whole number followed by 'and', then the fractional part, such as 'two and three tenths' for 2.3.
Explanation:
When a decimal is written in word form, the indication that the equivalent form is a mixed number rather than a fraction is the presence of a whole number followed by the word 'and', then the fractional part.
For example, 'two and three tenths' (2.3 in numeric form) is a mixed number, as it has a whole number 'two' and the fractional part 'three tenths'. In contrast, a number written solely as 'three tenths' would represent just a fraction (0.3 in numeric form).
