The question requires matching verbal descriptions of numbers with their corresponding numeric representations using decimal notation. The place value of each digit is used to determine the correct numeric form of the verbal description.
Explanation:When matching the verbal descriptions to the correct number sentences, you will use the value of each place within a number to write it in decimal notation. For example, in the number 1837, the digit 7 is in the ones place (10⁰ = 1), the digit 3 is in the tens place (10¹ = 10), the digit 8 is in the hundreds place (10² = 100), and the digit 1 is in the thousands place (10³ = 1000). This helps us correctly identify the number sentences.
Seven thousand, twenty-eight: 7,028Seven thousand, two hundred eight: 7,208Seven thousand, two hundred eighty-eight: 7,288Seven thousand, eight hundred twenty-eight: 7,828Seven thousand, eighty-eight: 7,088Two thousand, five hundred seventy: 2,570Two thousand, five hundred seven: 2,507Two thousand, five hundred seventy-seven: 2,577Two thousand, fifty-seven: 2,057Two thousand, seventy-seven: 2,077Nine thousand, nine: 9,009Nine thousand, nine hundred: 9,900Nine thousand, ninety: 9,090Nine thousand, ninety-nine: 9,099Nine thousand, nine hundred ninety-nine: 9,999

A mans hourly wage increased from 12.50 to 13.50. What percent raise did he get
Answer:
The man got a 8% raise.
Step-by-step explanation:
Percentage change = [Increase or decrease in value / Original Value]*100
Increase in hourly wage = [tex]13.5-12.5[/tex]
=[tex]1[/tex]
Percentage raise = [Increase in hourly wage / Initial hourly wage]*100
=[tex]\frac{1}{12.5} *100[/tex]
= [tex]8[/tex]%
The man got a 8% raise.
The man's hourly wage increased from $12.50 to $13.50 which, following the formula for calculating percentage change, indicates that he received an 8 percent raise in his hourly wage.
Explanation:Given that the man's hourly wage increased from $12.50 to $13.50, we can use the formula for calculating the percentage change to find out what percent raise he got.
The formula for calculating the percentage change is as follows:
[(change in quantity)/(original quantity)] × 100
In this case, the change in quantity (the man's wage increase) is $1.00 (13.50 - 12.50), and the original quantity (the man's original wage) is $12.50.
Plugging these values into the formula, we get:
[1.00/12.50] × 100
This calculates to an 8 percent wage increase. Therefore, the man got an 8 percent raise in his hourly wage.

Apply the vertical line test. Think of a vertical line moving from left to right in the graph. If the graph of the relation intersects the vertical line in more than one point in any position of the vertical line, then the relation is not a function.
The only graph that passes the vertical line test is the graph at the bottom right.

Are O, N, and P collinear? If so, name the line on which they lie.
We are given a figure where M, N , O and P points are given.
We need to explain if points O, N, and P collinear or not.
Note: All co-linear points are in a straight line.
From the figure, we can see that O and N points are in a straight line but point P is aside.
So, the points O, N, and P are not collinear.
Therefore, correct option is "No, the three points are not collinear".

Use the diagram and the following equation to solve for x.

113 + (2x + 5) = 180
x=___
Starting with 113+ (2x+5)=180, combine like terms and to get 118+2x=180. Subtract 180-118, which gives you 62. Then you have 2x=62. Divide both sides by 2 to get a final answer of x=31.
Hey there!!
Given :
... 113 + ( 2x + 5 ) = 180
Subtract 113 on both sides
... 2x + 5 = 180 - 113
... 2x + 5 = 67
Subtract 5 on both sides
... 2x = 62
Divide by 2 on both sides
... x = 31

How do I find the zeros of x^4-10x^3-66x^2-94x-39
Answer: x = -1, -3, 7 + √62, 7 - √62
Step-by-step explanation:
q p
x⁴ - 10x³ - 66x² - 94x - 39
[tex]\frac{p}{q}[/tex] = +/- [tex]\frac{1*3*13*39}{1}[/tex]
possible rational factors: 1, -1, 3, -3, 13, -13, 39, -39
Use synthetic division or long division to see which factor will leave a remainder of 0.
try x + 1 = 0 ⇒ x = -1
-1 | 1 -10 -66 -94 -39
| ↓ -1 11 55 39
1 -11 -55 -39 0
(x + 1)(x³ - 11x² - 55x - 39)
next, try x + 3 = 0 ⇒ x = -3 for the new polynomial

| ↓ -3 42 39
1 -14 -13 0
(x + 1)(x + 3)(x² - 14x - 13)

x + 1 = 0 ⇒ x = -1
x + 3 = 0 ⇒ x = -3

The ratio of blue paint to yellow paint in a green paint mixture is 2:3.If you use 16 ounces of blue paint,how many ounces of yellow paint do you need?
Answer:
24 ounces.
Step-by-step explanation:
Given that the ratio of blue paint to yellow paint in a green paint mixture is 2:3.
Actual ounces used for blue paint = 16
By ratio and proportion property we have
2:3 = 16:x where x is the actual ounces of yellow paint used.
Simplify using ratio rules
if a:b = c:d then ad = bc
We get
2x=3(16) = 48
Divide by 2
x = 24
Hence 24 ounces of yellow paint to be used.

Why did the queen have the king measure the rug
The queen might've asked the king to measure the rug to demonstrate humility, responsibility, highlight practical skills, or grasp the concept of measurement. Without specific context, however, it's hard to pinpoint an exact reason.
Explanation:Without specific context, it's difficult to provide an exact reason for the queen asking the king to measure a rug. However, in general, English literature often showcases rulers partaking in ordinary tasks as a means of demonstrating humility, responsibility, or attention to detail. For instance, the queen might have wanted the king to measure the rug in order to prove that he can attend to ordinary matters as well as royal duties, or perhaps to prove himself practical and not merely ceremonial. It could also be a ploy to make the king grasp the concept of measurement, size or area, by doing the task himself.

This can be written as:

Using the Middle term factorization.
3x² + (10 + 3)x - 10 = 0
3x² + 10x + 3x - 10 = 0
This is not possible so,
Using determinant.

Un cheatah puede recorrer 20 kilometros en 10 minutos. Si pudiera mantener esta velocidad durante una hora ,? cuantos kilometros recorreria
Answer:
If you can maintain this speed you will travel 120 km in 1 hour.
Explanation:
The translated question is, A cheetah can travel 20 kilometers in 10 minutes. If I could maintain this speed for one hour, how many kilometers would you travel?.
Let us find the speed of cheetah
Distance traveled = 20 km
Time taken = 10 minutes = 10/60 = 1/6 hours
So speed = [tex]\frac{20}{\frac{1}{6} } =120[/tex]km/hr.
So speed of cheetah = 120 km/hr, which means cheetah will travel 120 km in 1 hour.
If you can maintain this speed you will also travel 120 km in 1 hour.

Solve each inequality and check which inequality has -12 as a solution
a. [tex]x+6<-8[/tex]
Subtract 6 from both sides
[tex]x<-14[/tex]
b. [tex]x+4>-6[/tex]
Subtract 4 from both sides of the inequality to get x alone

Also given that there are equal amounts of each colour
Let n be the no of marbles of each colour.
Then total no of marbles = 5(n) = 5n

(1). We say that ∠ACB and ∠BCD are supplementary, from linear pair of postulate.
(2). ∠ACB + ∠BCD =180°, because ∠ACB and ∠BCD are supplementary (from the difinition of supplementary angles).
(3). ∠ACB +45° = 180° because ∠BCD =45°(substitute).
(4).Subtraction properties of equality ( because we subtract 45 degree from both sides of the previous equation).
(5). ∠ABC is obtuse, because m∠ABC grater than 90°.
(6). From the definition of obtuse triangle (ΔACB is an obtuse triangle because ∠ACB =135 degree which is grater than 90 degree).
