Mr. Morris asked Rob to shovel the snow from his driveway every day that it snowed during the month of January. He agreed to pay Rob $0.01 for the first day, $0.02 for the second day, $0.04 for the third day, $0.08 for the fourth day, and so on. If it snowed for 13 days in January, how much would Mr. Morris pay Rob on the 13th day?
Do not answer if you do not know. Only good answers with explanations.
Answer:
Total amount to be paid on 13th day is $40.96.
Step-by-step explanation:
Mr. Morris pays Rob $0.01, $0.02, $0.04 ..... on 1st, 2nd , 3rd .... day respectively.
We can clearly see that the next number is becoming double of the previous value.
The above sequence of numbers are in a Geometric Progression with
First term, a = 0.01 and
Common ratio, r = 2
We have to find the total amount paid on 13th day.
We know that the [tex]n^{th}[/tex] term of a GP is given by:
[tex]a_{n} =ar^{n-1}[/tex]
Where, a is the first term of GP
r is the common ratio
We have to find the [tex]13^{th}[/tex] term of the GP as per question statement.
Putting the values in the formula above:
n = 13
a = 0.01 and
r = 2
[tex]a_{13} = 0.01 \times 2^{13-1}\\\Rightarrow 0.01 \times 2^{12} \\\Rightarrow 0.01 \times 4096\\\Rightarrow 40.96[/tex]
Total amount to be paid on 13th day is $40.96.

Eric, Cam, and Brooke are playing a game of mini golf on a computer. The computer program for the game stores
objects in terms of I and y coordinates. All coordinate values are in meters.
The players are shooting at the hole, which is located at (3,2). After hitting their initial shots, Eric's golf ball is at
(-6,6). Cam's golf ball is at (8,-6), and Brooke's golf ball is at (10,8).
If the player whose ball is farthest from the hole should shoot next, which player should shoot next?
Choose 1 answer:
Answer:
Eric
Step-by-step explanation:
For we solve this problem, we have to determine the distance of each player to the hole using the distance formula.
D = √(x2-x1)²+(y2-y1)²
The hole for Eric is
The hole is at (3,2)
Eric's golf ball is at point (-6,6)
= √(-6-3)²+(6-2)²
= √-9²+4²
= √81+16
= √97
= 9.85 approx
The for Brooke
The hole is at (3,2)
Brooke's golf ball is at point (10,8)
= √(10-3 )²+(8-2)²
= √7²+6²
= √ 85
= 9.22 approx
Base on the two values gotten, Eric distance is more far compare to Brooke, therefore Eric should be the one to shoot next .

Which math sentence can be used to determine if this triangle is a right triangle?
Side 12
Side 15
Side 18
12+ 15 = 18
122+ 152 = 182
12+18 = 15
122+ 182 – 152
Answer:
12^2 + 15^2 = 18^2
Step-by-step explanation:
If we have 3 sides of a triangle we can use the Pythagorean theorem to determine if the triangle is a right triangle
a^2 + b^2 = c^2
12^2 + 15^2 = 18^2
If this is true, then the triangle is a right triangle

Answer:
[tex]v=\left[\begin{array}{ccc}1i\\0j\end{array}\right][/tex]
Step-by-step explanation:
We know that the given unit vector is in the direction of the x-axis.
Remember that an unit vector is a vector which magnitude is the unit, that's why is called like that.
So, the given unit vector can be written as [tex]v=1i+oj[/tex], where [tex]i[/tex] indicates the horziontal coordinate and [tex]j[/tex] indicates the vertical coordinate.
As a vertical or colum vector would be
[tex]v=\left[\begin{array}{ccc}1i\\0j\end{array}\right][/tex]
Therefore, the answer is
[tex]v=\left[\begin{array}{ccc}1i\\0j\end{array}\right][/tex]
If a wiggling string has a natural frequency of 34.5 Hz to produce 4 harmonics, what is the period of the string?
Answer:
[tex] T = \frac{1}{f}[/tex]
And replacing we got:
[tex] T = \frac{1}{34.5 Hz}= 0.0290 s[/tex]
And then we can conclude that with the conditions given the period of the string would be 0.0290 s
Step-by-step explanation:
For this case we know the frequency associated to the 4 harmonic.
We know that by definition the frequency is the inverse of the period:
[tex] f= \frac{1}{T}[/tex]
If we solve for the period we got:
[tex] T = \frac{1}{f}[/tex]
And replacing we got:
[tex] T = \frac{1}{34.5 Hz}= 0.0290 s[/tex]
And then we can conclude that with the conditions given the period of the string would be 0.0290 s

100 = 5 x
(4 + 2)
ANSWER: 100=5*6
100=30
HOPE IT HELPS!
Answer:
x = 3 1/3
Step-by-step explanation:
Let's go over the order of operations.
P: Parentheses
E: Exponents
M/D: Multiplication/division (in order of appearance)
A/S: Addition/Subtraction (in order of appearance)
100 = 5*(4 + 2)
Since there are values in parentheses, solve those first: 100 .= 5x(6).
Next, multiply 5x by 6. 100 = 30x.
Finally, divide each side by 30 to find the value of x. 3 1/3 = x
Therefore, the value of x is 3 1/3.
(Note: this is assuming the term "x" is a variable, and not the multiplication sign, *.)

Makayla has 90 minutes to answer 36 questions on a school survey. How many minutes per
question does she have?
Answer:
Makayla has 2 and a half minutes to answer each question.
Step-by-step explanation:
To get two and half you will have to divide 90 from 36 then you get 2 and a half minutes. hope this helps =D
By using division as mathematical operation,
Makayla need 2 and half minutes to answer each question
What is division?"The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication. In simple words, division can be defined as the splitting of a large group into smaller groups such that every group will have an equal number of items. It is an operation used for equal grouping and equal sharing in mathematics."
We have
Number of minutes to answer 36 questions = 90
We have to divide 90 by 36
= [tex]\frac{90}{36}[/tex]
= 2.5 minutes
Hence, By using division as mathematical operation, Makayla need
2 and half minutes to answer each question.

Answer:
So it gives you a little picture and tells you what would the question be if you had this graph.
Step-by-step explanation:
The correct answer would be B, find the area because the 4x + 3 is your length and 3x is your length, A = length * width. So the answer is B, find the area.
Answer:
Step-by-step explanation:
A) Length = 4x +3
Width = 3x
Perimeter = 2*(length + width )
= 2*(4x + 3 + 3x) {Add the like terms}
= 2*(7x + 3)
= 2*7x + 2*3
= 14x + 6
B) Area = length * width
= (4x + 3) * 3x
= 4x *3x + 3*3x
= 12x² + 9x
C) x = 8
Perimeter = 14x + 6 = 14*8 + 6 =112 +6 = 118 units
Area = 12x² + 9x = 12*(8)² + 9*8
= 12*64 + 72
= 768 + 72
= 840 square units
At the amusement park each students is given $16 dollars for food. This covers the cost of 2 meals plus $4 for snacks. how much money does the school expect each student to spend per meal. Which equation can be used to represent this situation? plz help now if u can
Answer:
16 = 2x + 4
Step-by-step explanation:
The total amount of money they are given is $16. That is split up into 2 equal groups with 4 left over. So you'd have to subtract 4 from both sides. Then divide both sides by 2. This will give you the answer to how much money they expect the students to spend on food.
