Answer:
aₙ = 63 * (1/3)ⁿ
Step-by-step explanation:
In the sequence 63, 21, 7,... each term is divided by 3 to get the next term
Therefore, this is a geometric series where r (the common ratio) is 1/3.
The first term in the series is 63, so that is our a₀.
The general form for a geometric series is a₀ * rⁿ
Therefore, the formula for aₙ is
aₙ = 63 * (1/3)ⁿ

12) The function f(x) represents the total bill from a rental store that charges $10 to rent a power tool pus an
additional $2 an hour. A second rental store uses the function glx) = 15 + 1.5x to represent the total bill
for a similar power tool. Which of the following statements is true?
(A)
(B)
The function f(x) has a greater rate of
change than function g(x).
The function g(x) has a greater rate of
change than function f(x).
(C)
(D)
The rates of change cannot be determined.
The rates of change for both f(x) and
g(x) are equal

What value of x and y makes the 2 triangles congruent by ASA? Find the measures of angle QPR and QRP
Given:
Two triangles congruent by ASA.
To find:
The the measures of x, y, angle QPR and angle QRP.
Solution:
The triangles PQR and PSR are congruent by ASA. So,
[tex]\angle QPR\cong \angle SPR[/tex]
[tex]PR\cong PR[/tex]
[tex]\angle QRP\cong \angle SRP[/tex]
Now,
[tex]m\angle QPR=m\angle SPR[/tex]
[tex]2x+1=x+18[/tex]
[tex]2x-x=18-1[/tex]
[tex]x=17[/tex]
And,
[tex]\angle QRP= \angle SRP[/tex]
[tex]8y-4=4y+28[/tex]
[tex]8y-4y=4+28[/tex]
[tex]4y=32[/tex]
Divide both sides by 4.
[tex]y=8[/tex]
The measure of angle QPR is:
[tex]m\angle QPR=(2x+1)^\circ[/tex]
[tex]m\angle QPR=(2(17)+1)^\circ[/tex]
[tex]m\angle QPR=(35+1)^\circ[/tex]
[tex]m\angle QPR=36^\circ[/tex]
And,
[tex]m\angle QRP=(8y-4)^\circ[/tex]
[tex]m\angle QRP=(8(8)-4)^\circ[/tex]
[tex]m\angle QRP=(64-4)^\circ[/tex]
[tex]m\angle QRP=60^\circ[/tex]
Therefore, the required values are [tex]x=17, y=8, m\angle QPR=36^\circ ,m\angle QRP=60^\circ[/tex].
After rain, water flows over the Sutherland Falls at a rate of 74240 litres per second. This is an increase of 45% on the rate before the rain. Calculate the rate before the rain.
Answer: 51,200 litres per second
Step-by-step explanation:
Assume that the rate before the rain is denoted as x.
This would mean that 74,240 liters per second is an increase of 45% over the value of x.
In formula form therefore this is:
74,240 = x + (x * 45%)
74,240 = x + 0.45x
74,240 = 1.45x
x = 74,240 / 1.45
x = 51,200 litres per second
Help fast!! What is the exact volume of the cylinder?
36
324
54
18 in
Answer:
V = 54 pi in ^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
V = pi (3)^2 * 6
V = pi (9) *6
V = 54 pi in ^3

Answer:
3^4 (3rd option)
:)
Answer:
the answer is optionc) 3 is to power 4 because
3 is to power 4 mean to multiply the whole number 3 itself 4 time which is 81,greater than 4ia to power 4
example
4 Is to power3=4×4×4=64
7 is to power 2 =49
5is to power 2=25
3 is to power 4 =81
2 is to power 5=32
therefore option c is greater than 4 is to power 3

Of the flags in Albert's Flag Shop, 1/10 are pink and another 1/2 are orange. What fraction of the flags are either pink or orange?
Answer: 6/10
Step-by-step explanation: The answer is 6/10 because: first you convert the 1/2 to tenths which would be 5/10. Then, you add 1/10 and 5/10 and you get 6/10 of the flags were either pink or orange.
Write an
inequality that describes the number line above.
Answer:
x > 6
Step-by-step explanation:
The number line shows all values above 6. However, it does not include 6 since the circle is not filled in. This inequality will describe "all values above 6" or x > 6.
Find the slope of the line that contains (−3,−3) and (−4,−8).

Solve for x and y in the diagram below:
x = 2.8 and y = 3.5
O x = 2.1 and y = 4.5
O x = 4.4 and y = 2.4
O x = 7.3 and y = 5.6
Answer:
x will equal 2.1
y will equal 4.5
supplementary angles: look at the attachment to see the question
Answer:
x = 21
Step-by-step explanation:
21 x 3 = 63 and 63 + 67 = 130 and sense there across from eachother this is correct because vertical angles are always the same measure.

Answer:
Volume of cuboid = 300 in³
Surface area of cuboid = 280 in²
Step-by-step explanation:
Given:
Length = 10 in
Width = 5 in
Height = 6 in
Find:
Volume of cuboid
Surface area of cuboid
Computation:
Volume of cuboid = [L][B][H]
Volume of cuboid = [10][5][6]
Volume of cuboid = 300 in³
Surface area of cuboid = 2[lb][bh][hl]
Surface area of cuboid = 2[(10)(5) + (5)(6) + (6)(10)]
Surface area of cuboid = 2[50 + 30 + 60]
Surface area of cuboid = 2[140]
Surface area of cuboid = 280 in²
Answer:Volume of cuboid = 300 in³
Surface area of cuboid = 280 in²
Step-by-step explanation:
A rectangular plot measures 20 cm by 10 cm on a map. If is drawn to the scale 1:1000. What is the actual area of the piece of land in hectares ?
Answer:
Solution given:
length [l]=20cm
breadth [b]=10cm
area of rectangle =l×b=20×10=200cm²
since 1cm=1000cm
than real area =200×1000²=200000000cm²
since
1 hectares =10000m²=10000×10000=100000000cm²
so
200000000cm²=2hectares
So,actual area of the piece of land in hectares is 2 hectares.
