By definition, the absolute value of a constant is the distance from that number to zero, regardless of it's negative or positive coefficient.
The distance from -38 to 0 is 38, meaning that the absolute value is 38.
Hope this helps.
頑張って!
Answer:
38
Step-by-step explanation:
The absolute value of a number may be thought of as its distance from zero along real number line. which means - 38 is 38 times away from 0

1. Here is a map that shows parts of Texas and
a. About how far is it from Amarillo to Oklahoma City?
b. Driving at a constant speed of 70 miles per hour, will it be possible to make this
trip in 3 hours?
Answer:
a). 240 miles (Approx)
b). Trip can't be covered in 3 hours with a constant speed = 70 miles pr hour
Step-by-step explanation:
a). As the scale has been given at the bottom. Length of the scale represents the distance between two points.
Now by measuring the distance between these stations, approximate distance between Amarillo and Oklahoma = 4(length of the scale)
= 4×60
= 240 miles.
b). Driving at a constant speed = 70 miles per hour
Distance covered in 3 hours = 70 × 3
= 210 miles
Therefore, distance of 240 miles between these stations can't be covered with the driving speed 70 miles per hour in 3 hours.

A bag contains 4 red marbles, 5 blue marbles, 6 yellow marbles, and 7 green marbles; Jonathan randomly grabs one marble, puts it back then draws a second marble. What is the probability that the first marble was red, and the second marble was green?
p ( first marble red ) = 4/22
p ( second marble green ) = 7/22
Since total number of marbles r 22, then the denominator is 22 also. When Jonathan puts back the red marble aft the first round, this means with replacement so there's no change in denominator for the second round.

Best regards! :D
The standard form of the polynomial -4w(w²-9) will be -4w³+36w.
What are polynomials?A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.
The highest degree of terms is written first, followed by the next degree, and so on, to represent a polynomial in standard form.
The given expression can be converted to the standard form as below,
P = -4w(w²-9)
P = ( -4w) x (w²) + ( 4 x 9w)
P = -4w²+36w
Therefore, the standard form of the polynomial -4w(w²-9) will be -4w³+36w.

What is 0.16666666666666666 as a fraction?
Answer:
[tex]\frac{1}{6}[/tex]
Step-by-step explanation:
We require to create 2 equations with the repeating 6 placed after the decimal point. Then subtracting the equations eliminates the repeating part.
let x = 0.1666....... ( multiply both sides by 10 and 100 )
10x = 1.666...... → (1)
100x = 16.666...... → (2)
Subtract (1) from (2) to eliminate the repeating decimal, thus
90x = 15 ( divide both sides by 90 )
x = [tex]\frac{15}{90}[/tex] = [tex]\frac{1}{6}[/tex]
Thus

Step-by-step explanation:
If you have a calculator with distribution functions, this problem boils down to using a single command:
norm(70.8, 85.2, 78, 2.4) = 0.9973
This tells us that 99.73% of the scores are in the 70.8-85.2 range.

Nathan read a total of 630 pages over 30 hours. In all, how many hours of reading will Nathan have to do this week in order to have read a total of 714 pages? Solve using unit rates.
Answer:
34 hours
Step-by-step explanation:
Given that,
Nathan read a total of 630 pages over 30 hours.
We need to find times of reading will Nathan have to do this week in order to have read a total of 714 pages.
1 page can be read in [tex]\dfrac{30}{630}\ \text{hours}[/tex]
To read 714 pages, it will take

Elegant Home Architects charge $75.00 per hour for the house plans. Let ℎ represent the number of hours for which the Johnson family hires the design firm. Which of the following statements are true? Select all that apply. -The expression 50ℎ represents the total charge for Rock the House Digital Designs. -The expression 75ℎ represents the total charge for Elegance Home Architects. -The cost for using Rock the House Digital Designs for an initial consultation only is $550. -If the Johnson family hires the design firm for 15 hours, then Elegance Home Architects will be cheaper. -If the Johnson family hires the design firm for 40 hours, then Rock the House Digital Designs will be cheaper.
Answer:
The expression 75ℎ represents the total charge for Elegance Home Architects.
If the Johnson family hires the design firm for 15 hours, then Elegance Home Architects will be cheaper.
If the Johnson family hires the design firm for 40 hours, then Rock the House Digital Designs will be cheaper.
Step-by-step explanation:
Given the following :
Rock the house digital designs :
Initial consultation charge = $500
Additional hour of work for house plan = $50 /hr
Elegant Home Architect:
Charge = $75 / hr
h = number of hours fro which Johnson's family hires the design firm
Total amount charged by Elegant home Architect = 75 × h = 75h
Total amount charged by Rock the house digital design = (500 + 50h)
If h = 15 hours :
Total amount charged by Elegant home Architect = 75 × 15 = $1,125
Total amount charged by Rock the house digital design = (500 + 50(15)) = 500 + 750 = $1,250
Hence, Elegant home Architect is cheaper.
If h = 40 hours :
Total amount charged by Elegant home Architect = 75 × 40 = $3,000
Total amount charged by Rock the house digital design = (500 + 50(40)) = 500 + 2000 = $2,500
Hence, Rock the house digital design is cheaper.

What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Let's say that number is x
Saying sum x with 9.4 means we need to add x and 9.4
So,
⇒ x + 9.4
Hence "The sum of x and 9.4 will be x + 9.4".
