Answer:
The nth term is 109-9n
Step-by-step explanation:
Here, we want to find the nth term of the given arithmetic sequence
Mathematically, we have the nth term as;
Tn = a + (n-1)d
where a is the first term which is 100 in this case
d is the common difference which is the value obtained by subtracting the preceding term from the succeeding term; it is constant throughout the sequence
The value here is thus;
82-91 = 91-100 = -9
Substituting these values
Tn = 100 + (n-1)-9
Tn = 100 -9n + 9
Tn = 100 + 9 - 9n
Tn = 109-9n
Show all your work! Thank you!
Answer: B
Step-by-step explanation:
x = van
y = bus
12x + 9y = 456
1x + 2y = 83
(Simplify equations)
9y = -12x + 456
y = -1.3x + 456/9
2y = -x + 83
y = -1/2x + 41.5
(Find x)
-1.3x + (456/9) = -.5x + 41.5
0.8x = 9.16
(Round)
x = 11
(Find y by plugging x in)
y = -1/2(11) + 41.5
y = -5.5 + 41.5
y = 36
(Check)
12(11) + 9(36) = 456
132 + 324 = 456
1(11) + 2(36) = 83
11 + 72 = 83
Simplify the following in simplest radical form of sqrt{40}

what is the order pair for y=1/3x
Answer:
Step-by-step explanation:
y is always (1/3) of x.
Thus, if x = 0, y = 0; if x = 1, y = (1/3)(1) = 1/3, and so on. The corresponding ordered pairs are (0, 0), (1, 1/3), (-2, -2/3)
can someone help me with this please?
Answer:
1) m∠AB'C = 41°
2) m∠BAC = 49°
3) m∠B'AC = 49°
4) m∠ACB = 90° Given
5) m∠ACB' = 90°
6) [tex]\overline {AB'}[/tex] = 24
7) Isosceles triangle
8) True
Step-by-step explanation:
Given that triangle ΔABC, is the reflection of ΔAB'C, and given that a reflection is a rigid transformation, we have;
1) ΔABC ≅ ΔAB'C Given
∴ m∠AB'C ≅ m∠ABC given that Corresponding Parts of Congruent Triangles are Congruent (CPCTC)
m∠AB'C = m∠ABC by the definition of congruency
∴ m∠AB'C = m∠ABC = 41°
2) Similarly, we have;
m∠BAC = 180° - (90° + 41°) = 49° Given the sum of interior angles of a triangle theorem
m∠BAC = 49°
3) m∠BAC = m∠B'AC by CPCTC
∴ m∠B'AC = m∠BAC = 49° by transitive property
m∠B'AC = 49°
4) m∠ACB = 90° Given
5) ∴ m∠ACB' = 90° given that the sum of angles on a straight line is 180°
6) [tex]\overline {AB}[/tex] = 24 Given
[tex]\overline {AB}[/tex] ≅ [tex]\overline {AB'}[/tex] given that ΔABC ≅ ΔAB'C and CPCTC
[tex]\overline {AB}[/tex] = [tex]\overline {AB'}[/tex]
[tex]\overline {AB'}[/tex] = [tex]\overline {AB}[/tex] = 24
[tex]\overline {AB'}[/tex] = 24
7) In ΔABB', [tex]\overline {AB'}[/tex] = [tex]\overline {AB}[/tex] = 24 therefore, ΔABB' has two sides equal and ΔABB' Is an isosceles triangle
8) True, the angles opposite the congruent sides are the base angles of the isosceles triangle and they are therefore congruent

Paul has $65 saved in his bank account. He withdrew $3 each month until he had $38. For how many months did Paul withdraw money
Answer: 9 months
Explaination: First subtract the total price which is $65 and subtract it by the final amount of money he had which is $38. Doing this you should get $27. To find the number of months divide it by 3 and you should get 9 months! Hope this helps! :)
Answer:
9 months
Step-by-step explanation:
$65 - $38 = $27 (the amount of money he had withdrew.)
27 ÷ 3 = 9
(since every month Paul withdrew $3.)
So, Paul withdrew $27 from his original balance of $65 to get his ending balance of $38. That means, if Paul withdrew $3 each month, he withdrew money for 9 months.

A countertop is 11 feet long and 4 fee t wide.
What is the area of the countertop in square meters? Use the conversion 1 foot = 0.305 meter. Round your
final answer to 2 decimal place
Answer:
4.09m^2
Step-by-step explanation:
A countertop is 11 feet long and 4 fee t wide.
Using the conversion
1foot = 0.305 meter
11fet = 11(0.305)
11feet = 3.355 m
4 feet= 4 * 0.305
4feet = 1.22m
Area of the countertop = Length * Width
Area of the countertop = 3.355 * 1.22
Area of the countertop = 4.0931m^2
Hence the required area is 4.09m^2 to 2 decimal places

If m\angle VXW=28\degreem∠VXW=28°, what is the measure of arc VW?
Answer:
m(arc VW) = 56°
Step-by-step explanation:
m∠VXW = 28°
By inscribed angle theorem,
"Length of intercepted arc measures the double of the inscribed angle"
m(arc VW) = 2m(∠VXW)
m(arc VW) = 2(28°)
m(arc VW) = 56°
Therefore, measure of arc VW is 56°.
