Florida has 8 less than 5 times the number of counties ,a, in Arizona. Georgia has 25 more than twice the number of counties, f, in Florida. Write an expression for the number of counties in Florida. Write an expression for the number of counties in Georgia.Arizona has 15 counties. How many do Florida and Georgia have? Number of counties Florida has: Number of counties Georgia has:
Answer:
Number of countries in Florida=5×a-8
Number of countries in Georgia=2×f+25
Step-by-step explanation:
Given that the number of countries in Florida is denoted by f, number of countries in Arizona is given by a and the number of countries in Georgia is given by g.
as Florida has 8 less than five times the number of countries in Arizona
So f=5×a-8
Georgia has 25 more than twice the number of countries in Florida
So g=2×f+25
Now it is given that Arizona has 15 countries i.e. a=15
So f=5×15-8
f=67
g=2×67+25
g=159
Hence, number of countries in Florida is:67
number of countries in Georgia is:159
Florida has 67 counties and Georgia has 159 counties, based on the expressions given and the number of counties stated for Arizona.
Explanation:The number of counties in Florida is represented by the expression 5a - 8, where 'a' is the number of counties in Arizona. Given that Arizona has 15 counties, we substitute 'a' with '15' in the expression to get 5*15 - 8 = 67. Hence, Florida has 67 counties.
The number of counties in Georgia is represented by the expression 2f + 25, where 'f' is the number of counties in Florida. Given that Florida has 67 counties, we substitute 'f' with '67' in the expression to get 2*67 + 25 = 159. Hence, Georgia has 159 counties.

The graph of f(x) = 2x + 1 is shown below. Explain how to find the average rate of change between x = 0 and x = 3.
Answer:
The rate of change is 7/3
Step-by-step explanation:
To find the average rate of change, we subtract the value of the function at the 2 points, over the difference of the 2 points.
f(3) -f(0)
-----------
3-0
f(3) = 2^(3)+1 = 8+1 =9
f(0) = 1 +1 = 1
9 -2
-----------
3-0
7/3
The rate of change is 7/3
Each line is one unit.
When X = 0, the blue line is at Y = 2
When x = 3, the blue line is at Y = 9
The average rate of change would be the change in y over the change in x.
The change in y = 9 - 2 = 7
The change in x = 3-0 = 3
The average rate of change would be 7/3
Which two answers are correct ?
Answer:
Choice A) x and f(x) approach negative infinity
Choice D) x and f(x) approach positive infinity
Step-by-step explanation:
A cubic curve starts low and ends high if the leading coefficient is positive, which in this case it is. This means that the left side of the graph falls while the right side rises. Your teacher might say something like "fall to the left, rise to the right" to describe what the end behavior is doing.
More formally "fall to the left" means that as x approaches negative infinity, y = f(x) is approaching negative infinity as well. Similarly, "rise to the right" indicates that as x approaches infinity, y = f(x) heads off to infinity as well. Both x and y = f(x) move in the same direction along their respective number lines; eg, if one goes in the negative direction, then so does the other.

Calculate the shaded area.
Give your answer to 3 significant figures and state it’s units.
To calculate the shaded area, determine the area of the entire shape and the area of the shaded region. Subtract the area of the shaded region from the area of the entire shape to find the shaded area.
Explanation:To calculate the shaded area, we first need to determine the area of the entire shape. Let's say the shape is a rectangle with a length of 10 units and a width of 6 units. The area of the rectangle is given by multiplying the length by the width, so in this case, the area is 10 units x 6 units = 60 square units.
Next, we need to determine the area of the shaded region. Let's say the shaded region is a right triangle with a base of 4 units and a height of 3 units. The area of a triangle is given by multiplying the base by the height and dividing by 2. So, the area of the shaded triangle is (4 units x 3 units) / 2 = 6 square units.
Finally, we can calculate the shaded area by subtracting the area of the shaded triangle from the area of the entire shape. The shaded area is 60 square units - 6 square units = 54 square units.

You can buy 20 ounces of cereal for 4.40$ or 16 ounces of the same brand for 3.68$ which is the better buy?
To find the better buy, we can find how much they cost for an ounce and find it by comparison.
First option:
20/4.4
=$4.545454...
Second option:
16/3.68
=$4.3478...
As $4.3478..< $4.5454.., the second option is cheaper and therefore is the better buy.
Hope it helps!
The 20 ounces for $4.40 is the better deal at $0.22 per ounce, compared to the 16 ounces for $3.68 at $0.23 per ounce.
To determine which cereal is the better buy, we need to calculate the cost per ounce for each option. For the first option of 20 ounces at $4.40, the cost per ounce is:
[tex]\frac{0.44}{20} = 0.22 ~per ounce[/tex]
For the second option of 16 ounces at $3.68, the cost per ounce is:
[tex]\frac{3.68}{16} = 0.23[/tex]
Comparing these two costs per ounce, the 20 ounces for $4.40 is the better buy because it has a lower cost per ounce.

There are 3 girls and 4 boys in the Reese's family. Mr Reese's booth 6 1/2 pounds of candy. How much will each kid get
Answer:
Each Child get = 0.928 pounds of candy
Step-by-step explanation:
Total no of girls are 3
total no of boys are 4
Total no boys and girls are = 3 + 4
= 7
Now it is given that Mr Reese booth have some pound of candies and he wants to distribute it equally among each children
total candy Mr Reese have is [tex]6\frac{1}{2}[/tex]
Now converting it to proper fraction
[tex]6\frac{1}{2}[/tex] =[tex]\frac{6*2+1}{2}[/tex]
= [tex]\frac{13}{2}[/tex]
Now the amount of candy have =[tex]\frac{13}{2}[/tex]
Now we have to divide it into 7 kids
so
each kid get = total candy / total children
=[tex]\frac{13}{2}[/tex]÷7
Changing the divide sign to multiplication
[tex]=\frac{13}{2}*\frac{1}{7}[/tex]
Which becomes
[tex]=\frac{13}{14}[/tex]
solving it gives
Each Child get = 0.928 pounds of candy

Determine which of the following exponential formula(s) represents II and IV in the graph above.
Answer:
A [tex]\alpha ,\beta[/tex]
Step-by-step explanation:
Step 1
The first step is to notice that the graphs of II and iv have the same y intercept. This means that we are looking for functions that match the condition that when t=0, the two functions have the same value. The functions [tex]10(1.02)^t,10(1.05)^t[/tex] meet that condition. Additionally the functions [tex]30(0.95)^t,30(1.05)^t[/tex] meet this condition.
Step 2
The other condition that must be met by the 2 functions is that they should both increase with the increase in increasing values of t. the function [tex]30(0.95)^t[/tex] does not meet this condition. This means that only the functions [tex]\alpha ,\beta[/tex] are the only functions that meet this condition.
Answer:
a. α and β
Step-by-step explanation:
One way to solve this exercise is by analyzing the y - intercept of the functions.
By looking at the graph, we can see that II and IV have the same y - intercept.
All the formulas below depend of the variable ''[tex]t[/tex]'' so if we want to find the y - intercept we only need to replace by ''[tex]t=0[/tex]'' in the formulas.
We can also see that the y - intercept of II and IV will be the lower that the another y - intercept of the functions.
If we replace by [tex]t=0[/tex] :
(α)(t) = [tex]10.(1.02)^{t}[/tex] ⇒ [tex]10.(1.02)^{0}=10[/tex]
(β)(t) = [tex]10.(1.05)^{t}[/tex] ⇒ [tex]10.(1.05)^{0}=10[/tex]
(χ)(t) = [tex]20.(1.02)^{t}[/tex] ⇒ [tex]20.(1.02)^{0}=20[/tex]
(δ)(t) = [tex]30.(0.85)^{t}[/tex] ⇒ [tex]30.(0.85)^{0}=30[/tex]
(ε)(t) = [tex]30.(0.95)^{t}[/tex] ⇒ [tex]30.(0.95)^{0}=30[/tex]
(Φ)(t) = [tex]30.(1.05)^{t}[/tex] ⇒ [tex]30.(1.05)^{0}=30[/tex]
We find that the lowest y - intercept (also equal) are the y - intercept of α and β. Therefore, the correct option is a. α and β
Why are units of area inappropriate to measure volume? A) Units of area are too small to measure volumes. B) Units of area are too large to measure volumes. C) Area is a two-dimensional attribute and volume is a three-dimensional attribute. D) Area is a three-dimensional attribute and volume is a two-dimensional attribute.
Answer:
The correct answer is option C
Step-by-step explanation:
Area is usually the planar lamina of a two dimensional figure and usually expressed in units square meter, square feet, square inches etc.
While Volume is the total space occupied by an object in a 3-D setting and is usually expressed in cubic meter, cubic feet, cubic inches etc.
A 2-D dimension can not represent a 3-D structure and thus units of area inappropriate to measure volume
Consider the diagram what is the length of segment ab
The length of segment AB is 9 units. So the answer is B) 9.
To find the length of segment AB, we can use the angle bisector theorem, which states that in a triangle, the length of the angle bisector from a vertex to the opposite side is proportional to the lengths of the two segments of that side.
Let's denote the length of AB as x.
Given that BC = 9 units and B is the midpoint of AC, AC = BC = 9 units.
Given that AD = 16 units.
Since B is the midpoint of AC, we can deduce that AB = BC = 9 units.
Therefore, the correct answer is B) 9.

Solve by multiplication and addition. Show each step of your work. 2x – 3y = 18 4x + y = 8 Please help me!!!! I am giving 50 points!
Answer:
(x, y ) = (3 , - 4 )
Step-by-step explanation:
given the 2 equations
2x - 3y = 18 → (1)
4x + y = 8 → (2)
multiply (2) by 3
12x + 3y = 24 → (3)
add (1) and (3) term by term to eliminate the term in y
(2x + 12x) + (- 3y + 3y) = (18 + 24)
14x = 42 ( divide both sides by 14 )
x = 3
substitute x = 3 in (1) or (2) to evaluate for y-coordinate
(2) → 12 + y = 8 ⇒ y = 8 - 12 = - 4
solution is (3, - 4 )

Answer:
The answer is 19.0000. 38 divided by two = t. (19)
Step-by-step explanation:
The approximate solution of an equation is simply an estimate of the solution.
The approximate solution of 2t = 38 is (d) 19.0000
The equation is given as:
[tex]\mathbf{2t =38}[/tex]
Start by dividing both sides of the equations by 2
[tex]\mathbf{\frac{2t}{2} =\frac{38}2}[/tex]
Divide 2t by 2, to give 2
So, we have
[tex]\mathbf{t =\frac{38}2}[/tex]
Divide 38 by 2 to give 19
[tex]\mathbf{t =19}[/tex]
From the list of given options, 19.0000 approximates to 19.
So, the solution of the equation can be rewritten as:
[tex]\mathbf{t =19.0000}[/tex]

Caitlin went to the store to buy school clothes .She had a store credit from from a previous return in the amount of $39.58 if she bought 4 of the same style shirt in different colors and spent atotal of $52.22 after the store credit was taken off her total, what was the price of each shirt she bought?
Answer: The price of each shirt she bought was $22.95.
Step-by-step explanation:
Hi, to answer this, first, we have to add to the discounted price (52.22) the amount of the credit (39.58), to obtain the original total cost (without discount).
So:
52.22+39.58 = $91.8
Since she bought 4 shirts, we have to divide the total cost by 4:
91.8 /4 = $22.95
The price of each shirt she bought was $22.95.

Given equal angles in two figures, we prove that the angles formed by CWD and FZG, as well as DWE and GZH, are equal, thus showing m∠CWE = m∠FZH.
To prove that m∠CWE = m∠FZH, we can use the information given and apply the transitive property of equality. We have the following information:
Given:
1. m∠1 = m∠2 (angles 1 and 2 are congruent)
2. m∠3 = m∠4 (angles 3 and 4 are congruent)
We want to prove:
m∠CWE = m∠FZH
Now, let's construct a table to demonstrate the proof step by step:
| Statement | Reason | Lines Used |
|-------------------|--------------------------------------|------------------|
| 1. m∠1 = m∠2 | Given | Given |
| 2. m∠3 = m∠4 | Given | Given |
| 3. m∠CWD = m∠FZG | Corresponding angles are congruent | Definition of ∠ |
| 4. m∠DWE = m∠GZH | Corresponding angles are congruent | Definition of ∠ |
| 5. m∠CWD + m∠DWE = m∠FZG + m∠GZH | Adding equal quantities to equal quantities | Addition Property of Equality |
| 6. m∠CWE = m∠FZH | Angles CWD and DWE form ∠CWE, and angles FZG and GZH form ∠FZH | Definition of ∠ |
In lines 3 and 4, we use the definition of corresponding angles to show that angles CWD and FZG are congruent and angles DWE and GZH are congruent.
