Answer:
The percentage change (an increase) wa 40%.
Step-by-step explanation:
The beginning number of acres was 100; adding 40 more brought that to 140 acres. This was an increase. Dividing the increase (40) by the starting value (100) yields 0.40. Finally, multiplying this result by 100% yields 40%.
The percentage change (an increase) wa 40%.

The exterior angles of a quadrilateral have measures of 80°, 65, 2x", and 3x . Find the value of x.
Answer:
80°+65°+2x+3x=360°(sum of quadrilateral is 360)
145°+5x=360°
5x=360°-145°
5X=215°
X=215°/5°
X=43°
The required value is [tex]x=43[/tex]
Given angles are,
[tex]80^{\circ}, 65^{\circ}, 2x,3x[/tex]
As we know the sum of all angles in the quadrilateral is [tex]360^{\circ}[/tex].
Then we have the relation,
[tex]80+65+2x+3x=360\\\\145+5x=360\\5x=360-145\\5x=215\\x=43[/tex]
So, the value of the x is 43.

5. Write an equivalent expression to 1/4 (24x + 7 – 12x).
Answer:
Step-by-step explanation:
The easiest and most proper way to approach this task is to combine like terms inside parentheses: (24x + 7 – 12x) => (12x + 7).
Then (1/4)(24x + 7 – 12x) = (1/4)(12x + 7). This is an acceptable answer. There is the option of carrying out the multiplication, which results in
3x + 7/4, which is another acceptable answer.

Which graph represents the function f(x) = 3/2(2)x
The fourth graph represents the function [tex]f(x)=\frac{3}{2} 2^{x}[/tex]
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given function is [tex]y=\frac{3}{2} 2^{x}[/tex]
It is an exponential function and 2>1, therefore it is an increasing in nature.
put x=0 in the given function to find the y-intercept of the graph.
f(0)=3/2.2⁰
f(0)=3/2(1)
f(0)=3/2=1.5
So, the y-intercept is 1.5.
In figure 1 and figure 1 the y-intercept is 1, in figure 2 the y-intercept is 2 , therefore first three options are incorrect.
In figure 4 the y-intercept is 1.5, therefore the option 4 is correct.
Hence, the fourth graph represents the function [tex]f(x)=\frac{3}{2} 2^{x}[/tex]

[tex]\boxed {\boxed {\sf x \approx 23.49 \ cm }}[/tex]
Step-by-step explanation:
This is a right triangle (the small square in the corner signifies a 90 degree angle), so Pythagorean Theorem can be used.
[tex]a^{2} + b^{2} =c^{2}[/tex]
where a and b are the legs of the triangle and c is the hypotenuse. In this triangle, 17 and x are the legs because they form the right angle. 29 in the hypotenuse because it is opposite the right angle.
[tex]a= 17 \\b=x \\c= 29[/tex]
[tex]17^{2} + x^{2} =29^{2}[/tex]
Solve the exponents.
17²=17*17=28929²= 29*29=841[tex]289+x^{2} =841[/tex]
289 is being added to x and the inverse is subtraction. Subtract 289 from both sides to isolate the variable.
[tex]289-289+ x^{2} =841-289\\x^{2} =552[/tex]
x is being squared and the inverse is a square root. Take the square root of both sides of the equation.
[tex]\sqrt {x^{2} }=\sqrt {552}[/tex]
[tex]x=23.4946802489[/tex]
Let's round to the nearest hundredth. The 4 in the thousandth place tells us to leave the 9.
[tex]x \approx 23.49[/tex]
x is approximately 23.49 centimeters.
Find the explicit formula for a 1 =-4,a n =a n-1 +9,n>=2
Given:
[tex]a_1=-4[/tex] and [tex]a_n=a_{n-1}+9[/tex] where [tex]n\geq 2[/tex].
To find:
The explicit formula for the given recursive formula.
Solution:
We know that recursive formula of an AP is:
[tex]a_n=a_{n-1}+d[/tex]
Where, d is the common difference.
We have,
[tex]a_n=a_{n-1}+9[/tex]
Here, d=9.
The first term of the AP is [tex]a_1=-4[/tex].
The explicit formula for an AP is:
[tex]a_n=a_1+(n-1)d[/tex]
Substituting [tex]a_1=-4[/tex] and [tex]d=9[/tex], we get
[tex]a_n=-4+(n-1)9[/tex]
[tex]a_n=-4+9n-9[/tex]
[tex]a_n=-13+9n[/tex]
Therefore, the required explicit formula for the given sequence is [tex]a_n=-13+9n[/tex].

Jodi's best score on a video game is 50 points. Mark's best score on the game is 1.5 times as much as Jodi's best score. How many points did Mark score on the video game? Mark's best score on the game is points. Virginia's best score is only 0.3 times Jodi's best score. How many points did Virginia score on the game? Virginia's best score is points.
Answer:
a) Mark's best score on the game is 75 points.
b) Virginia's best score is 15 points.
Step-by-step explanation:
Jodi's best score on a video game is 50 points.
a) Mark's best score on the game is 1.5 times as much as Jodi's best score. How many points did Mark score on the video game?
Mark's best score on the game is calculated as:
1.5 times as much as Jodi.
Jodi's best score = 50 points
= 1.5 × 50 points
= 75 points
b) Virginia's best score is only 0.3 times Jodi's best score. How many points did Virginia score on the game? Virginia's best score is points.
Virginia's best score on the game is calculated as:
0.3 times as much as Jodi.
Jodi's best score = 50 points
= 0.3 × 50 points
= 15 points
Virginia's best score is 15 points.

The ratio of squirrels to pigeons in the park is 15 to 125. Which statement describes this relationship?
Answer: A. There are 3 squirrels for every 25 pigeons in the park
Step-by-step explanation:
The options include:
A) There are 3 squirrels for every 25 pigeons in the park.
B) There are 3 squirrels for every 5 pigeons in the park.
C) There are 5 squirrels for every 3 pigeons in the park.
D) There are 25 squirrels for every 3 pigeons in the park.
Since the ratio of squirrels to pigeons in the park is 15 to 125. The common factor we have here is 5. We can then divide the figures given by 5. This will be:
= 15/125 = (15/5)/(125/5) = 3/25
This mean that for every 3 squirrels, there are 25 pigeons in the park.
Therefore, the correct answer is A.

She will hire EZ Excavation.
Step-by-step explanation:
For a company EZ Excavation,
Per cubic yards cost of the dirt = [tex]\frac{\text{Total cost}}{\text{Volume of the dirt}}[/tex]
= [tex]\frac{196}{8}[/tex]
= $24.5
Total cost of 40 cubic yards of the dirt = 40 × 24.5
= $980
For second company Happy Hauling service,
Per cubic yard cost of the dirt = [tex]\frac{25}{1}[/tex]
= $25
Cost of 40 cubic yards of the dirt = 40 × 25
= $1000
Budget of the contractor = $1000
Cost of dirt offered by EZ Excavation is in her budget and she is saving $20.
Therefore, she will hire EZ Excavation.
