At the beginning of the year, Alyssa had $100 in savings and saved an additional $7 each week thereafter. Colton started the year with $55 and saved $10 every week. Let AA represent the amount of money Alyssa has saved tt weeks after the beginning of the year and let CC represent the amount of money Colton has saved tt weeks after the beginning of the year. Write an equation for each situation, in terms of t,t, and determine the amount of money Alyssa and Colton have saved in the week that they have the same amount of money saved.
Answers
The equation that represents the amount saved by Alyssa after tt weeks is AA = 100 + $7tt
The equation that represents the amount saved by Colton after tt weeks is CC = $55 + $10tt
The amount they would have when they have same amount of money is $205.
What equation represents the total amount saved?The total amount saved: inital amount + (amount saved per week x total number of weeks
AA = 100 + $7tt
CC = $55 + $10tt
What would be the amount when they have the same amount of money?$55 + $10tt = 100 + $7tt
Combine similar terms and solve for tt
100 - 55 = 10tt - 7tt
45 = 3tt
tt = 15 weeks
100 + $7(15) = $205

A square pyramid is shown. What is the surface area of the pyramid? Enter your answer in the box. 100 points
Answers
Answer:
33 cm²
Step-by-step explanation:
Formula
Surface Area = 4 x Area (triangle) + Area (square)S.A. = 4 x 1/2 x bh + b²Solving
Given that h = 4 cm and b = 3 cmS.A. = 2 x 4 x 3 + 3²S.A. = 24 + 9 = 33 cm²Answer:
33 cm²
Step-by-step explanation:
Since the pyramid has a square base, the area of each of the triangular sides will be the same.
Therefore, to calculate the total surface area, find the area of one triangle, multiply it by 4, then add it to the area of the square base.
Formulae
Area of a square = x³ (where x is the side length)
Area of a triangle = 1/2 × base × height
Calculation
area of the square base = 3² = 3 × 3 = 9 cm²
area of one triangle = 1/2 × 3 × 4 = 6 cm²
Solution
Total area = area of the square base + 4 × area of one triangle
= 9 + (4 × 6)
= 9 + 24
= 33 cm²

The water of the cylinder cannot fill the container, since the cylinder has less volume. Lastly, there is no apparent mistakes.
How to determine if two volumes are equivalent?The rectangular container ([tex]V_{R}[/tex]), in cubic inches, is full whether its volume is equal to the volume of the cylinder ([tex]V_{C}[/tex]), in cubic inches. The volume formulae for both containers are described below:
Rectangular container[tex]V_{R} = w\cdot l \cdot h[/tex] (1)
Where:
[tex]w[/tex] - Width, in inches[tex]l[/tex] - Length, in inches[tex]h[/tex] - Height, in inchesCylinder[tex]V_{C} = \pi\cdot r^{2}\cdot h[/tex] (2)
Where:
[tex]r[/tex] - Radius, in inches[tex]h[/tex] - Height, in inchesNow we proceed to determine the volume of each figure:
Rectangular container (w = 3.6 in, l = 3.6 in, h = 5.3 in)[tex]V_{R} = (3.6\,in)\cdot (3.6\,in)\cdot (5.3\,in)[/tex]
[tex]V_{R} = 68.688\,in^{3}[/tex]
Cylinder (r = 1.8 in, h = 5.3 in)[tex]V_{C} = \pi\cdot (1.8\,in)^{2}\cdot (5.3\,in)[/tex]
[tex]V_{C} \approx 53.947\,in^{3}[/tex]
The volume of the water in the cylinder is approximately 53.947 cubic inches. The water of the cylinder cannot fill the container, since the cylinder has less volume. Lastly, there is no apparent mistakes. [tex]\blacksquare[/tex]

Pierre has more money than Alex.
If Pierre gave Alex £20, they would have the same amount.
If Alex gave Pierre £22, then Pierre would have twice as much as Alex.
How much does each one actually have?
Answers
Answer:
Pierre has £ 146 and
Alex has £ 106
Step-by-step explanation:
Let the money with Pierre be = p
Let the money with Alex = a
If Pierre gave Alex £20, they would have the same amount.
So, we should subtract £ 20 from p and add £ 20 to a
p - 20 = a + 20
p = a + 20 + 20
p = a + 40 ----------------(I)
If Alex gave Pierre £22, then Pierre would have twice as much as Alex.
p + 22 = 2*(a -22)
p + 22 = 2a - 44
p = 2a - 44 - 22
p = 2a - 66
p -2a = - 66 -----------------(II)
Substitute p = a + 40 in equation (II)
a + 40 - 2a = -66
a - 2a + 40 = -66
-a = - 66 - 40
-a = - 106
Multiply both sides by (-1)
[tex]\boxed{a = \£ \ 106}[/tex]
Substitute a = 106 in equation (I)
p = 106 + 40

As ray UW bisects ( divides the angles into two equal parts )
WUT = WUV
6x - 10° = 4x + 6°
6x - 4x = 6° + 10°

x = 16° ÷ 2 = 8°
Putting the value of x in the Angle WUT

On the same coordinate plane, mark all points (x, y) that satisfy each rule.
y = -3 -X
Answers
The rule y = -3 - x is an illustration of a linear equation
The points on the coordinate plane with the rule y = -3 - x are (0,-3), (1,-4) and (2,-5)
How to determine the points?The rule of the points is given as:
y = -3 - x
When x = 0, we have:
y = -3 - 0
y = -3
When x = 1, we have:
y = -3 - 1
y = -4
When x = 2, we have:
y = -3 - 2
y = -5
From the above computation, we have the following points
(0,-3), (1,-4) and (2,-5)
Hence, the points on the coordinate plane with the rule y = -3 - x are (0,-3), (1,-4) and (2,-5)

A pillar is fixed in the centre of a circular meadow with diameter of 60 metres. The angle of elevation of its top was found to be 60%, when observed from a point of the circumference of circular meadow. Find the height of the pillar from the ground.
Answers
Answer:
17 meters
Step-by-step explanation:
|\ angle = 60 degrees here of triangle
| \ <-- digitaly drawn triangle
|___\
cirlcle diameter is 60 meters, since pillar is at the center then the distance of the pillar to the edge of the circlular meadow is (60/2) 30 meters.
30 meters is opposite of the angle.
The height of the pillar is adjacent to the angle so use tangent to solve
Tan(60) = 30/x
Tan(60) = 1.7; make sure that calculator is in degrees and not in radians to not get an incorrect value
1.7 = 30/x --> 1.7x = 30
x = 30/1.7
x = 17.3205 meters
using 2 significant figures gives us 17 meters
How many ways can 8 books be arranged on a shelf? Show all of your work for full credit.
Answers
There are 40,320 ways, in which 8 books can be arranged on a shelf.
Solution:Here, we are to find the number of ways in which 8 books can be arranged on a shelf. The total number of books is 8 and the way of arranging books is also 8.
If one book is placed in the first place, then 7 books will be placed in front of it. If 2 books are placed in the 2nd place, then only 6 books can be placed after that book. This sequence will continue till 1 .Permutations :
A permutation is an arrangement of objects in a definite order.➲ P ( n, r )= n ! / ( n - r ) !
n = total number of objectsr = number of objects selectedThe number of ways to arrange 8 books on a shelf will be :
➝ P ( n, r ) = n ! / ( n - r ) !
➝ P ( n, r ) = 8 ! / ( 8 - 8 ) !
➝ P ( n, r ) = 8 ! / 0 !
➝ P ( n, r ) = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 / 1
➝ P ( n, r ) = 40, 320
ㅤㅤㅤㅤㅤㅤ~ Hence, there are 40,320 ways in which 8 books can be arranged on a shelf !
If the 3 books can't be together (but any 2 of the 3 can be) then it's 36,000 ways. If any one of the 3 books can't touch either of the other 2, it's 15,840 ways.
Explanation:I'm not sure if the question is saying that all three books can't be together in a group (and so biology and history can be together, but biology, history and programming can't), or if the books in that group can't sit next to other books in the group (and so biology and history can't be together). Let's do it both ways - case 1 will be all three together and case 2 will be any 2 together.
Before we work this, let's first see the number of ways we can have all 8 books arranged. Order matters and so we can approach this using a permutation equation. Moreover, since we're using all the books, we'll end up with the total number being:
8 ! = 40 , 320 .
