Answer:
Price of Truck after 2 year = $ 19802.50
Step-by-step explanation:
Given: Price of truck = $ 25,000
Price depreciate at rate of 11% in a year
To find: Price of truck after 2 years
If we let Price of truck to be P = $ 25000
And Rate of deprecation to be R = 11%
And time to be n = 2
now by using formula of deprecation, we get
[tex]A=P\times(1-\frac{R}{100})^n[/tex]
[tex]A=25000\times(1-\frac{11}{100})^2[/tex]
[tex]A=25000\times0.7921[/tex]
A = $ 19802.50
Therefore, Price of Truck after 2 year = $ 19802.50
What is the missing term in the factorization? 18x2−32=2(3x+?)(3x−4)
Answer:

2(3x-4)(3x+4)
So, the missing term is 4.
The missing term in the factorization 18x² − 32 = 2(3x + ?)(3x − 4) is 4.
What is Factorization ?Factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form. Factorization is expressing a mathematical quantity in terms of multiples of smaller units of similar quantities.
For an integer, Factorization is decomposition of that integer in terms of smaller integers; when multiplied with each other give back that considered number. Those composing integers are called factors of that considered integers.
WE have given an expression as;
18x² − 32 = 2(3x + ?)(3x − 4)
Now we apply difference of squares;
2(9x² - 16)
2(3x + 4)(3x - 4)
OR
2(3x-4)(3x+4)
Therefore, the missing term is 4.

The box plots show male and females grades in mathematics class: Which of the following best describes the information about the interquartile ranges?
Answer:
The interquartile ranges are quite close in value.
Step-by-step explanation:
We have been given two box-plots and we are asked to choose the correct statement about the interquartile ranges.
Since we know that interquartile range is difference between upper and lower quartile.
[tex]IQR=Q_3-Q_1[/tex]
Let us find IQR for the female grades in math.
We can see from box-plot representing female grades that upper quartile is about 90 and lower quartile is about 75.
[tex]\text{IQR of female grades}=90-75[/tex]
[tex]\text{IQR of female grades}=15[/tex]
Now let us find IQR for the male grades in math.
[tex]\text{IQR of male grades}=85-70[/tex]
[tex]\text{IQR of male grades}=15[/tex]
We can see IQR values for males and females are same, therefore, last statement is true.

if right triangle LMN, L and M are complementary angles and sin (L) is 19/20 what is cos (M)
Answer: Value of cos(M) is
[tex]\cos M=\frac{19}{20}[/tex]
Step-by-step explanation:
Since we have given that
LMN is a right angled triangle where L and M are complementary angles ,
And,
[tex]\sin L=\frac{19}{20}=\frac{Perpendicular}{Hypotenuse}[/tex]
so, we will find base now by using "Pythagorus theorem":
[tex]H^2=B^2+P^2\\\\20^2=B^2+19^2\\\\400=B^2+361\\\\400-361=B^2\\\\39=B^2\\\\\sqrt{39}=B[/tex]
As we know that side opposite to mentioned theta is considered as perpendicular as shown in the figure ,
For M as [tex]\theta[/tex]
NL will be its perpendicular and MN will be its base and to find the cos(M) we use Base and Hypotenuse.
So, now we will find cos(M) i.e.
[tex]\cos M=\frac{Base}{Hypotenuse}=\frac{19}{20}[/tex]
Hence,
[tex]\cos M=\frac{19}{20}[/tex]

For a field trip, a bus company charges a flat fee plus an additional fee per student. for 25 students, the total cost is 132.50. if there are 30 students, the total cost is 145. which equation represents the total cost y of the field trip for x students?
Answer:
[tex]y=2.5x+70[/tex]
Step-by-step explanation:
First of all, this problem is modelled by a linear equation, where the ratio of change is the slope of the line.
Now, we know that [tex]x[/tex] represents students and [tex]y[/tex] represents the total cost.
The problem states that for 25 students, the total cost is $132.50. And for 30 students, the total cost is $145. This information represents two points
[tex](25,132.50)[/tex] and [tex](30,145)[/tex].
So, to find the equation, we first have to find the slope using these two point and the following formula
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} } =\frac{145-132.50}{30-25}=\frac{12.5}{5}=2.5[/tex]
This means the slope is 2.5
Now we use the point-slope formula to find the linear equation
[tex]y-y_{1} =m(x-x_{1} )\\y-145=2.5(x-30)\\y=2.5x-75+145\\y=2.5x+70[/tex]
Therefore, the equation that models this problem is
[tex]y=2.5x+70[/tex]
Where the flat fee is $70, and the fee per student is $2.5.
Which graph is represented by the following table?
The pictures show the table and graphs. The graphs are what can show which one is the answer.
Select the table that represents the following graph.
The stuff is on the links/screenshots
Answer:
The first image in your answer choices
Explanation:
To find the table of solutions for the given graph, we observe points on the graph that are intersected by the line.
The easiest starting point is often where the line intercepts (or crosses) the vertical y-axis. This occurs one unit above the origin (0,0), so we would say list this point as ordered pair (0, 1). This eliminates the third and fourth tables as answer choices.
Now we use the horizontal x-axis to find other points that the line crosses through. Starting at x = 1, we can see the line goes through the point 4 units above the x-axis here; therefore, its ordered pair is (1, 4). This eliminates the second table as an answer choice.
Let's use one more point to confirm we have the right choice. Starting at x = -1, we can see the line goes through the point 2 units below the x-axis here; therefore its ordered pair is (-1, -2).
The first table contains all of these ordered pairs (0, 1), (1, 4), and (-1, -2), making it your answer choice.
Find the value of x so that f || g. The diagram is not to scale.
Lines f and g are parallel with a transversal forming same side interior angles with measures 3x and 5x + 36.
Theorem: If parallel lines are cut by a transversal, then same side interior angles are supplementary.
The angles measuring 3x and 5x + 36 are supplementary, so their measures add up to 180 degrees
3x + 5x + 36 = 180
8x + 36 = 180
8x = 144
x = 18
The answer is x = 18.
Answer:
18
The answer is 18

Mr. Greenjeans planted 6 different crops on 2 acres of land. If half of it was planted with green beans, how many acres were planted with green beans?
To determine how many acres were planted with green beans, we simply take half of the total acreage. Mr. Greenjeans planted a total of 2 acres, so half of this is 1 acre; therefore, 1 acre was planted with green beans.
The question is asking how many acres were planted with green beans, given that Mr. Greenjeans planted crops on 2 acres of land and half of it was with green beans. To find the answer, we need to calculate half of the total land area.
Here is the step-by-step explanation:
Start with the total number of acres: 2 acres.Since half of the land was planted with green beans, we divide the total acres by 2.2 acres / 2 = 1 acre.Therefore, Mr. Greenjeans planted 1 acre of land with green beans.
Thomas has $6.35 in dimes and quarters the number of dimes is three more than three times the number of quarters how many quarters does he have?
let q represent the number of quarters then which of the following expressions represents the value of number of dimes in cents?
a)3q+3
b)6.35-q
c) 10(3q+3)
The answer is
c) 10(3q + 3)
because it is asking for the VALUE of the number of dimes, not the number of dimes. To get the value of the number of dimes, you have to take the equation 3q+3 and multiply it by 10.

What is the distance between points M and N?
___ meters.
Answer:
The distance between points M and N is 9.8m.
Step-by-step explanation:
It is given that JKL is a triangle and M and N are the mid points of the KL and JL respectively.
Now, if we join the mid points together that is MN, then we can see that the basic proportionality holds that is:
[tex]\frac{LM}{MK}=\frac{LN}{NJ}[/tex]
[tex]\frac{10.7}{10.7}=\frac{7.4}{7.4}=\frac{1}{1}[/tex] which holds.
And which also proves that MN is parallel to JK.
Now, if MN is parallel to JK, then the measure of MN will be half the measure of JK, that is:
[tex]MN=\frac{1}{2}JK[/tex]
[tex]MN=\frac{1}{2}(19.6)[/tex]
[tex]MN=9.8 m[/tex]
Thus, the measure of MN is 9.8 meters.

A quantity x varies directly with y and inversely with z. Which expression represents the constant of variation,k?
the answer is xz/y.
Answer:
The expression represents the constant of variation k is [tex]\frac{xz}{y}[/tex].
Step-by-step explanation:
As given
A quantity x varies directly with y and inversely with z.
[tex]x \propto y[/tex]
and
[tex]x \propto \frac{1}{z}[/tex]
Than combined the above equation.
[tex]x \propto \frac{y}{z}[/tex]
[tex]x = k\frac{y}{z}[/tex]
Where k is the constant of variation.
Than
[tex]k = \frac{xz}{y}[/tex]
Therefore the expression represents the constant of variation k is [tex]\frac{xz}{y}[/tex].
