Answer:
Fraction of fire trucks = [tex]\frac{1}{4}[/tex]
Total number of toy cars = [tex]16[/tex]
Step-by-step explanation:
Fraction of sports car = [tex]\frac{2}{3}[/tex]
Fraction of remaining cars [tex]=1-\frac{2}{3}=\frac{3-2}{3} =\frac{1}{3}[/tex]
So,
Fraction of pick up cars = [tex]\frac{1}{4}(\frac{1}{3})=\frac{1}{12}[/tex]
Therefore,
Fraction of fire trucks = [tex]\frac{1}{3}-\frac{1}{12}=\frac{4-1}{12}=\frac{3}{12}=\frac{1}{4}[/tex]
That is Number of fire trucks = [tex]\frac{1}{4}[/tex] ( Total number of toy cars )
Number of fire trucks = 4
Total number of toy cars = [tex]4(4)=16[/tex]

What is a rational number?A rational number is a number that can be written in the form of p/q where q is not equal to zero.
We have,
Sometimes True:
The sum of a rational number and an irrational number can be rational or irrational depending on the numbers chosen.
For example, 1 + √2 is irrational, but 1/2 + √2/2 is rational.
Always True:
The product of two rational numbers is always rational, as can be shown using the definition of rational numbers.
Always True:
The sum of an irrational number and a rational number is always irrational. This can be shown by contradiction.
Assume that the sum of an irrational number a and a rational number b is rational.
Then (a + b) - b is also rational, which implies that a = (a + b) - b is rational, contradicting the assumption that a is irrational.
Sometimes True:
The product of an irrational number and a rational number can be rational or irrational depending on the numbers chosen.
For example, √2 x 2 is irrational, but √2 x (1/√2) = 1 is rational.
Always True:
The sum of two rational numbers is always rational, as can be shown using the definition of rational numbers.

An airplane is flying diagonally across the state of Colorado. This state and its
dimensions are represented by the rectangle on the map shown.
Based on the measurements shown in the map, which measurement is closest to the
distance in miles the airplane will fly along the diagonal?
Answer:
C
Step-by-step explanation:
The measurement is closest to the distance in miles the airplane will fly along the diagonal is given by D = 476.1 miles
What is the diagonal of a rectangle?The diagonal of a rectangle is calculated by the formula
From the Pythagoras Theorem , The hypotenuse² = base² + height² , and
Diagonal of a Rectangle = √ ( Length )² + ( Width )²
Given data ,
Let the dimensions are represented by the rectangle be 280 mi x 385 mi
So , the length of the rectangular path L = 280 miles
The width of the rectangular path W = 385 miles
And , the distance in miles of airplane along the diagonal is given by
Diagonal of a Rectangle = √ ( Length )² + ( Width )²
On simplifying , we get
The distance along the diagonal D = √ ( 280 )² + ( 385 )²
The distance along the diagonal D = √ ( 78400 + 148225 )
The distance along the diagonal D = √ ( 226625 )
The distance along the diagonal D = 476.1 miles
Hence , the distance is D = 476.1 miles

Answer:
your answer is a complex number making your question wrong
Step-by-step explanation:
First z²+z+20=0, just to make it a quadratic equation, so we can use the quadratric formula:
x=( -b±√b²-4ac)/2a
so to find a b and c we compare
YOUR QUESTION SHOULD BE Z² +Z-20=O.
Which statement best describes the relationship between x and y in the equation y = 6 + x?
A The value of y is six less than the value of x.
B The value of y is six times the value of x.
C The value of x is six more than the value of y.
D The value of y is six more than the value of x.
Answer:
A. The Value of y is six less than the value of x
Step-by-step explanation:
This is because the value of x is equal to y when six is added.
What is the slope of the line that passes through the points (0, -4)) and (-2, -1)
Answer:
Step-by-step explanation:
y = mx + b
m is the slope (what you want)
b is the y-intercept, which is the value of y when x = 0
Oh, right, we already have b, isn't that great!
Given point (0, -4), so b = -4
Point (-2, -1), where x = -2 and y = -1
-1 = -2m -4 (solve for m)
3 = -2m
m = -3/2
Check:
y = -3x/2 -4
y = -3(-2)/2 -4 -> should get y = -1
y = 3 -4 = -1
Yay, we have the answer!

Part A: Which place is the least expensive place to purchase the coffeepot? Support your answer using words or numbers. (Round to the nearest
cent when calculating.)
Part B: Sales tax for all 3 retailers is 7.5%. What is the cost to purchase the cheapest coffeepot? (Round your answer to the nearest cent.)
Answer:
American Discounters is the cheapest.
Step-by-step explanation:
American Discounters:
149.49 - 30%
149.49 - (149.49 * 0.3) = 44.847
149.49 - 44.847 = 104.643
The Coffee Hut:
91.99 + 15%
91.99 + 13.8 = 105.79
