if the sum of interior angles of polygon is 1800
Answer:
12 sides
Step-by-step explanation:
Given
[tex]Sum =1800^o[/tex]
Required
The number of sides of the polygon
The sum of interior is calculated using:
[tex]Sum = 180 * (n - 2)[/tex]
Where
[tex]n \to[/tex] number of sides
So, we have:
[tex]Sum = 180 * (n - 2)[/tex]
[tex]1800 = 180 * (n - 2)[/tex]
Divide both sides by 180
[tex]10 = n - 2[/tex]
Add 2 to both sides
[tex]12= n[/tex]
[tex]n=12[/tex]

In ΔQRS, the measure of ∠S=90°, RQ = 41, QS = 9, and SR = 40. What is the value of the cosine of ∠R to the nearest hundredth?
Answer:
cos R = .98
Step-by-step explanation:
cos R = SR/QR
QR is the hypotenuse of the right triangle. By the Pythagorean theorem
(QR)^2 = (QS)^2 + (SR)^2
= 9^2 + 40^2
= 81 + 1600
= 1681
QR = 41
Cos R = adjacent side/hypotenuse = 40/41 = .98
The value of the cosine of ∠R to the nearest hundreth is 0.98.
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
The sides can also be found using pythagoras theorem. Therefore,
∠S = 90°
RQ = 41
QS = 9
SR = 40
cos R = adjacent / hypotenuse
Therefore,
adjacent side = 40
hypotenuse = 41
cos R = 40 / 41
cos R = 0.97560975609
cos R = 0.98

Teresa deposits $800 into an account that pays simple interest at a rate of 2% per year. How much interest will she be paid in the first 2 years?
Answer:
I'll setup the problem and you can do the computation
Step-by-step explanation:
The formula for simple interest:
I = P*r*t
I = interest
P = deposit
r = interest rate per period
t = number of periods
P = $800
r = 0.02
t = 2

The area of a trapezoid is given by
A = 1/2 ( b1+b2) h where b1 and b2 are the lengths of the bases and h is the height
We need to change 1 1/4 ft to inches = 1.25 (12) = 15 inches

A recent study indicated that the average cost of living for a family of four in various cities across the US was $65,351 with a standard deviation of $7712. A company is thinking about relocating to a city with a lower cost of living. They would like to choose a city in the bottom 30% of those surveyed. What is the cutoff for the cost of living that would make a city eligible for relocation by this company
Answer:
The correct answer is "57408".
Step-by-step explanation:
Given:
[tex]\mu=65351[/tex]
[tex]\sigma=7712[/tex]
[tex]p=0.15[/tex]
As per the standard table, we know,
[tex]z=-1.03[/tex]
Now,
⇒ [tex]z=\frac{x-\mu}{\sigma}[/tex]
By putting the values, we get
[tex]-1.03=\frac{x-65351}{7712}[/tex]
[tex]x=57407.64[/tex]
or,
[tex]=57408[/tex]

Sonia ran 6 miles more than twice as far as Brian if the total number of milesso you ran 6 miles more than twice as far as Brian if the total numbers of Miles run by both is 33 how far did each one run.
Answer: Brian ran 9 miles
Sonia ran 24 miles
Step-by-step explanation:
Let's Brian's distance be represented by x.
Since Sonia ran 6 miles more than twice as far as Brian. This will be:
= (2 × x) + 6
= 2x + 6
Therefore,
x + 2x+6 = 33
3x + 6 = 33
3x = 33 - 6.
3x = 27
x = 27/3
x = 9
Brian ran 9 miles
Sonia ran = 2x+6 = 2(9).+ 6 = 18+6 = 24 miles
A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
A) (x, y) → (x + 5, y – 3)
B) (x, y) → (x + 5, y + 3)
C) (x, y) → (x – 3, y + 5)
D) (x, y) → (x + 3, y + 5)
Answer:
C
Step-by-step explanation:
Any time you move up or down, it affects the "y" coordinate, and going up is positive so 5 units up is [tex]y + 5[/tex].
Moving left or right affects the "x" coordinate and moving left is negative so
[tex]x - 3[/tex]
[tex](x - 3, y + 5)[/tex]
Hence, C is the correct answer

Answer:
yes, yes, no; No
Step-by-step explanation:
We have to assume you have no trouble with single-digit addition and comparison of two numbers.
3+4 > 1 ⇒ 7 > 1 . . . . yes
4+1 > 3 ⇒ 5 > 3 . . . . yes
3+1 > 4 ⇒ 4 > 4 . . . . no
These lengths will not make a triangle because the triangle inequality is not satisfied.

You will notice that we found the result of interest when we added the two smallest numbers (1 and 3) and compared the sum to the largest number (4). This is a shortcut you can use for any "will these make a triangle" question. You don't need to bother comparing larger numbers to smaller ones. You already know they are larger.

Answer:
where is question? You are only showing answer.Dalaysia is participating in a walk-a-thon. One sponsor will donate $80 just for entering the race.
Another sponsor will donate $12 for each mile she walks. How many miles should she walk if she
wants to raise exactly $200 from those two sponsors? )
Let m represent the number of miles Dalaysia walks. Write an equation that
represents the number of miles Dalaysia needs to walk to raise exactly $200 from
the two sponsors. 1)
Answer:
10 miles to earn 200 cash
Steps:
80 + 12m = 200
12m = 200 - 80
12m = 120
12m/12 = 120/12
m = 10
Answer:
200 = 80+12m
10 miles
Step-by-step explanation:
She will get 80 from the first and 12m from the second
She needs 200
200 = 80+12m
Subtract 80 from each side
200 -80 = 12m
120 = 12m
Divide each side by 12
120/12 = m
10 =m
She needs to walk 10 miles
PLEASE HELP ME FIND THE AREA
Answer:
20m^2 or 20m squared
Step-by-step explanation:
a triangle's area is calculated by the formula hb/2 or height x base/2
in this triangle the height is 8m, and the base is 5m
therefore, the area is 8(5)/2 = 40/2 = 20
20m^2
Compute the product using (a) the definition where Ax is the linear combination of the columns of A using the corresponding entries in x as weights, and (b) the row-vector rule for computing Ax. If a product is undefined, explain why.
Answer:
When the number of rows or number of columns in the given matrix does not match the number of entries in the vector x.
When the number of columns in A [tex]\neq[/tex] the number of rows in B.
The matrix-vector is not defined.
Step-by-step explanation:
For example:-
Step 1:
Let's assume
[tex]A=\left ( \begin{matrix}-6 & 9\\ 2& 7\\ 1 & 0\end{matrix} \right )[/tex]3x2 & [tex]B=\left ( \begin{matrix}1\\ -6\\ 7\end{matrix} \right )[/tex]3x1
Since matrix multiplication of matric A and matrix B is only possible,
When the number of columns in A = Number of rows in B.
Step 2:
Let's A as m x n; Here m = rows and n=columns
B as p x q; Here p = rows and q=columns.
When n [tex]\neq[/tex] p, the matrix-vector is not defined.
That is matrix multiplication Ax is not possible.
Hence the matrix is not defined.

P varies inversely with the
square of Q. When Q is 8, P is 9.
Find the value of P when Q is 3.
The required value of P would be 64 for the given linear relationship.
What is the linear relationship?A linear relationship is a connection that takes the shape of a straight line on a graph between two distinct variables - x and y. When displaying a linear connection using an equation, the value of y is derived from the value of x, indicating their relationship.
Given that P varies inversely with the square of Q
P = k/Q²
As per the question, if Q is 8 and P is 9,
So 9 = k/8²
⇒ 9 = k/64
Apply cross-multiplication operation,
⇒ k = 576
If Q is 3, then
⇒ P = 576/3²
⇒ P = 576/9
Apply division operation, and we get
⇒ P = 64
Thus, the required value of P would be 64.
