I = a + (n - 1)d [Given formula]
To Find:-Find d when I = 10, a = 2, n = 5
Solution:-I = a + (n - 1)d [Given]
Putting the value of I = 10, a = 2, n = 5 we get,
10 = 2 + (5 - 1)d
10 = 2 + 4d
10 - 2 = 4d
8 = 4d
d = [tex] \frac{8}{4} [/tex]
d = 2
Value of d is 2. [Answer]A TV has a listed price of $751.98 before tax. If the sales tax rate is 8.75%, find the total cost of the TV with sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:
$817.78
Step-by-step explanation:
To find the tax you must do the equation:
751.98 x 0.0875
(Btw, 0.0875 is decimal form of 8.75%. Always turn the percentage into a decimal before finding the tax or sale amount)
751.98 x 0.0875 = 65.80.
Now, add the sale tax amount and the original price:
751.98 + 65.80 = 817.78
Therefore, the answer is 817.78.
So if I buy something for $26.98 and buy something else for $6.10 what will be the Total.
Answer:
33.08 $
I believe we add the two together and get our total !

Given cos 0 = 8/17, find sin 0.
sin 0 =
[?]
Simplify the fraction.
Answer:
Step-by-step explanation:
cos θ=8/17
sin θ=√(1-cos²θ)=√(1-(8/17)²)=√(1-64/289)=√((289-64)/289)=√(225/289)=15/17

Solve the following inequality
4 + 6x ≤ x + 6x
Select one:
A. x ≤ 4
B. x ≥ 4
C. x > 4
D. x < 4
Answer:
x ≥ 4
Step-by-step explanation:
The given inequality is :
4 + 6x ≤ x + 6x
Subtract 6x from both sides,
4 + 6x-6x ≤ x + 6x -6x
4≤ x
or
x ≥ 4
Hence, the correct option is (b) i.e. x ≥ 4.

A color printer prints 8 pages in 5 minutes.
How many minutes does it take per page?
Answer:
It takes 5/8 minutes or 0.625 minutes to print per page.
Step-by-step explanation:
The find the singular unit value of how long it would take per page you simply divide the amount that you are trying to figure out by the total amount of time you are taking and in this case it would be 5 divided by 8 in order to solve for the amount of minutes it takes per page.

Use the graph. How does the diagram show that the slope between any two points on a line is the same? A. It does not show this because the triangles are not the same size. B. The triangles have the same vertical heights and horizontal lengths. C. The distance between A and B is the same as the distance between B and C. D. The triangles are similar so the ratios of their vertical heights to their horizontal lengths are equivalent.
Answer:
the answer is D The triangles are similar so the ratios of their vertical heights to their horizontal lengths are equivalent.
Step-by-step explanation:
The triangles are similar so the ratios of their vertical heights to their horizontal lengths are equivalent. Therefore, option D is the correct answer.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
We know that, slope = Rise/Run.
Here, slope of a line AB = 3/6
= 1/2
Now, slope of a line BC = 2/4
= 1/2
Therefore, option D is the correct answer.

someone please help me answer this!!
Answer:
-5 63/100
Step-by-step explanation:
1.Write the expression in expanded form. The subscript number can be write in
normal form. E.g. X1 + X1Y1, do not forget the correct parenthesis and the correct
order. *
2.For the equation in above evaluate the notation using the values below. Please
enter the exact value.
X1 =0
Y1 = 5
Z1 = 0
X2 = 1
Y2 = 26
Z2 = -2
X3 = 12
Y3 = -2
Z3 = 3
X4 = -1
Y4 = 25
Z4 = 24
Answer:
(a) Expanded form:
[tex]((X_1 + X_1Y_1) - X_1Z_1) + ((X_2 + X_2Y_2) - X_2Z_2) + ((X_3 + X_3Y_3) - X_3Z_3) + ((X_4 + X_4Y_4) - X_4Z_4)[/tex]
(b) The value of the expression: -21
Step-by-step explanation:
Given
[tex]\sum \limit^4_{i=1}\ ((X_i+X_iY_i) - X_iZ_i)[/tex]
Solving (a): The expanded form:
This means that we substitute the values of i from 1 to 4 in the above expression.
So, the expression becomes:
[tex]((X_1 + X_1Y_1) - X_1Z_1) + ((X_2 + X_2Y_2) - X_2Z_2) + ((X_3 + X_3Y_3) - X_3Z_3) + ((X_4 + X_4Y_4) - X_4Z_4)[/tex]
Solving (b): The value of the expression
To do this, we simply substitute the given values of X1, X2....... in the expression.
This gives:
So, the expression becomes:
[tex]((0 + 0*5) - 0*0) + ((1 + 1*26) - 1*-2) + ((12 + 12*-2) - 12*3) + ((-1 + -1*25) - -1*24)[/tex]
Simplify each bracket
[tex]((0 + 0) - 0) + ((1 + 26) +2) + ((12 -24) - 36) + ((-1 -25) +24)[/tex]
[tex]0 + 29 -48 -2[/tex]
[tex]-21[/tex]
Hence, the result of the expression is -21
0.8km need to be convert into hour an minute please help
Answer:
It is not possible
Step-by-step explanation:
Required
Convert 0.8km to hours and minutes
One of the condition for a successful conversion is that: only units of the same metric can be converted.
i.e.
Meters can be converted to feet (they both measure distance)
Days can be converted to years (they both measure time)
Pounds can be converted to grams (they both measure weight)
But in the given question, you attempt to convert from distance to time.
This is not possible, because time and distance are different measurements

Many businesses and organizations insist that official communications use professional-looking fonts, such as Times New Roman. Fonts characterized as less professional, such as Comic Sans, should be avoided. A student would like to determine if font choice makes a difference in the average grade on a typed response in English classes. There are currently four English classes available from which the student can collect data, and each class has a similar writing assignment. That the start of the assignment, students are randomly assigned a font, either times new Roman or comic sans, and then complete the assignment the teachers grade the assignment and the mean grade for each font is found.
What is the response variable in this experiment?
A the font used by each h student
B, the teachers grading the responses
C the grade received on each assignment
D the length of the student response on the assignment
Answer:
C.
Step-by-step explanation:
The response variable can be defined as those variables that are considered to be the focus of a question in research or experiment. It is also known as a dependent variable and is marked on the y-axis. The response variable is explained with the help of an explanatory variable, marked on the x-axis. The other names for response variables are y-variables or outcome variables.
In the given case, the response variable is the grade received on each assignment. The grades received by students on each assignment are the main focus of this research.
Therefore, option C is correct.

value of x if 3x+2y=11 and 5x-y=14
Answer:
3x + 2y = 11
3x + y = 11 - 2
3x + y = 9
x + y = 9/3
x + y = 3
x = 3 - y
5x - y = 14
x - y = 14/5
x - y = 2.8
x = 2.8 + y
14Answer:
3
Step-by-step explanation:
solve for y in first equation
5x-y=14
-y=14-5x
y=5x-14
substitute y value (5x-14) into 2nd equation
3x+2 (5x-14)=11
3x+10x-28=11
