Answer:
Step-by-step explanation:
The sum of the measures of the interior angles of a decagon (10 sided polygon) is 1,440. We found this by using the formula (n-2)(180). Thus, to find the measure of each interior angle we simply divide the sum by the number of total sides in the polygon. 1,440/10 = 144.
I dont know how to do this, but this is what g**gle had to say about the matter. I hope this helps?

Triangle PQR is given to be a right triangle, so the Pythagorean theorem can be used to
Answers
Applying the Pythagorean theorem, we have ΔPQR ≅ ΔABC. then we would have: ∠ACB = ∠PRQ = 90°
What is the Pythagroean Theorem?The pythagorean theorem states that the square of the longest side (hypotenuse) of a right triangle is always equal to the sum of the squares of the other two sides (legs) of the right triangle.
Since we know that ΔPQR is a right triangle, then:
x² + y² = PQ²
We are also given that x² + y² = z², so by substitution, we have:
z² = PQ², which makes both triangles have corresponding congruent sides. Therefore, ΔPQR ≅ ΔABC.
Using the corresponding parts of the congruent triangles, we can conclude that: ∠ACB = ∠PRQ = 90°.

Their is a rectangle that has measurements in inches. If the width is 7/8 of an inch and the height is 2/3 of an inch, what is the AREA of the rectangle?
Answers
Answer:
Area of a rectangle = 7/12 of an inch
Step-by-step explanation
Area of a rectangle = Length × width
In this case, the length is represented by height
Height = 2/3 of an inch
Width = 7/8 of an inch
Area of a rectangle = Length × width
= 2/3 × 7/8
= (2 * 7) / (3 * 8)
= 14 / 24
= 7 / 12
Area of a rectangle = 7/12 of an inch

2 CDs and 9 DVDs cost £69. 2 CDs and 6 DVDs cost £48. i. Form a pair of simultaneous equations to represent these two sentences ii. Solve the simultaneous equations to find the cost of 1 CD and 1 DVD.
Answers
Answer:
Cost of 1 CD = x = £3
Cost of 1 DVD = y = £7
Step-by-step explanation:
Let us represent:
Cost of 1 CD = x
Cost of 1 DVD = y
i. Form a pair of simultaneous equations to represent these two sentences
2 CDs and 9 DVDs cost £69.
2x + 9y = 69.... Equation 1
2 CDs and 6 DVDs cost £48.
2x + 6y = 48..... Equation 2
ii. Solve the simultaneous equations to find the cost of 1 CD and 1 DVD.
Combining both equations together:
2x + 9y = 69.... Equation 1
2x + 6y = 48..... Equation 2
We substract Equation 2 from Equation 1
3y = 21
y = £7
Solving for x using Equation 1
2x + 9y = 69.... Equation 1
2x + 9 × 7 = 69
2x + 63 = 69
Collect like terms
2x = 69 - 63
2x = 6
x = 6/2
x = £3
Therefore,
Cost of 1 CD = x = £3
Cost of 1 DVD = y = £7

A cell phone company data about students texting skills.They collected the texting speed in words per minutes according to time in minutes.Identify the data's independent and dependent values
Answers
Answer:
independent variable = Time
Dependent variable = texting speed
Step-by-step explanation:
The Independent and dependent variables are used in regression analysis for making prediction. The Independent variable also called the predictor are the variables or data collected in other to influence or determine the outpjt obtained which is the dependent or predicted variable. Hence, the aim or prediction we wish to obtain, measure or determine is the dependent variable In the scenario above, the aim of the data collected is to determine the typing skill, here, the dependent variable is the typing skill. The data required to define the bthis is the data collected on typing speed which measures time taken to type.
Therefore, independent variable = Time
Dependent variable = texting speed
Subtract line 2 from line 1 to find your taxable income
Answers
Answer:
is there a pic?
Step-by-step explanation:
Your taxable income for the year is $42,000.
What is your available pay in an expense estimation?Your taxable income is the amount on which you are taxed in a tax calculation. Start with your $50,000 annual income as your base for the calculation.
Then, at that point, take away the allowances, which diminish your available pay, from the all-out pay. The deductions in this instance total $8,000 As a result, your taxable income will be $42,000, or $50,000 divided by $8,000.
This indicates that you will pay tax on $42,000, which will determine your tax bracket and the amount you owe. Deductions like contributions and expenses lower taxable income, thereby lowering the yearly tax bill.
Deduct the total income from the deductions to determine the taxable income:
Available pay = Complete pay - Allowances
Available pay = $50,000 - $8,000
Available pay = $42,000.
Your taxable income for the year is $42,000.

Profile: John John is a 35 year old, divorced man with one child (who lives with his mom). His take home pay is $4123 per month. He pays $1200 per month in child support to his ex-wife. He owns a 2-storey home and his monthly mortgage payments are $475 every 2 weeks. His car expenses total $145 monthly and his car insurance costs him $113 every month. His house insurance is $47.36 monthly. John also has an outstanding credit line of $8500. The only amount due on this account is the interest of about $55 monthly. However John is trying to pay off the credit line within the next 2 years, so he pays off as much of this loan as he can afford each month.
1.Use one highlighter to identify all sources of income. Total the income for each month.
2.Use a different highlighter to identify all sources of expense. Total the expenses for each month.
3. Subtract the Total Expenses from the Total Income for each
month. A Surplus is when your Income minus Expenses = a positive number.
A Shortage is when your Income minus Expenses = a negative number. Does he have a surplus or a shortage?
Answers
Answer:
1. Income highlight: $4123 of take home pay. That's it.
Total monthly income: $4123
------------------------------------
2. Expense highlight:
$1200 child support
$475 every 2 weeks
$145 car payment
$113 car insurance
$47.36 house insurance
$55 loan payment
Total monthly expense: $2510.36
(1200 + 2(475) + 145 + 113 + 47.36 + 55 = $2510.36
---------------------------------------------
3. $4123 - 2510.36 = 1612.64 surplus
--------------------------------------------
The only question remaining is what if they want him paying more on his credit line...it's kind of a variable expense at this point.
John also has an outstanding credit line of $8500. The only amount due on this account is the interest of about $55 monthly. However John is trying to pay off the credit line within the next 2 years, so he pays off as much of this loan as he can afford each month.
