Answers
Answer:
-16
Step-by-step explanation:
Given the sequence:
b(n)=b(n−1)−7, where b(1)=−2
b(2)=b(2−1)−7
=b(1)−7
=-2-7
b(2)=-9
Therefore, the 3rd term of the sequence
b(3)=b(3−1)−7
=b(2)-7 (Recall b(2)=-9 from above)
=-9-7
b(3)=-16
The 3rd term of the sequence is -16.

Consider the following ratios and state that whether these ratios forms a proportion?
Case1 - 20 friends to 15 strangers
Case 2 - 4 friends to 3 strangers
A. Yes
B. No
Part B
Find the ratio of the number of friends in Case 1 to the number of friends in Case 2.
Answer:_____________
Note: Type the answer as shown. Ex: (3:8)
Answers
Answer:
yes
Step-by-step explanation:
Be cause i whant points 20=15 7213=938401
Part A. Yes, these ratios forms a proportion
Part B- the ratio of the number of friends in Case 1 to the number of friends in Case 2 is 5:1
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
The ratios in cases 1 and 2 form a proportion. IT can be seen by dividing case a by 5 which gives 4:3;
i.e 20:15
If we divide both numerator and denominator by 5, then we have 4/3.
This shows case 1 and 2 have the same proportions of friends to strangers.
Part B; The number of friends in case 1 is 20 while in case 2 is 4.
we have, 20:4
= 20 4
Dividing each by 4, we have 5:1.
Which means that the ratio of friends that in case 1 to case 2 is 5:1.

cookie increases by 25%. Which expression best represents the new length of the
cookie?
A. 0.25y
B. 0.75y
C. 1.25y
D. 12.5y
Answers
Answer:
I think the answer is C
Step-by-step explanation:
If you have a normal ginger bread cookie, its full size would be 100%. So, if you add the first 25%, 1.25%
The expression best describes the new length of the cookie will be 1.25y.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that:-
An uncooked gingerbread cookie is y centimetres long. After it is baked, the length of the cookie increases by 25%.The initial length of the cookie is y after baking the length is increased by 25%
= y + 25%y
= y + ( 25 / 100 ) y
= y + 0.25 y
= 1.25 y
Therefore the expression best describes the new length of the cookie will be 1.25y.

StartRoot 11 EndRoot
StartRoot 22 EndRoot
StartRoot 61 EndRoot
StartRoot 72 EndRoot
Answers
Answer:
The answer is 61:)
Step-by-step explanation:
The concept distance formula is used here to determine the distance between two points. The distance between two points is the length of the line joining the two points. The distance between point X and point Y is 4√2 units.
What is distance formula?In analytical geometry, the distance formula is used to find the distance measure between two lines. The distance between two points of the xy-plane can be found using the distance formula.
The distance between two points is given as:
d = √(x₂ - x₁)² + (y₂ - y₁)²
d = √(-1 + 5)² + (3 - 7)²
d = √(4)² + (-4)² = √16 + 16
d = 4√2 units
Thus the distance between two points X(-5,7) and Y(-1,3) is 4√2 units.

An aquarium is designing a new exhibit to showcase clownfish and queen angelfish. The exhibit will hold a rectangular tank with length twice the size of the width, height is equal to 4 feet and total volume will equal to 500 cubic feet. What is a reasonable width of the tank to the nearest tenth of a foot?
Answers
Answer:
The width of the tank is approximately 7.9 feet.
Step-by-step explanation:
The pool is a rectangular prism with the following dimensions:
length = 2*x feet
width = x feet
height = 4 feet
With volume equal to 500 cubic feet, therefore:
volume = length*width*height = 500
(2*x)*(x)*(4) = 500
8*x² = 500
x = sqrt(500 / 8)
x = sqrt(62.5)
x = 7.90569 feet
The width of the tank is 7.9 feet.

Financial Literacy: Question 2Gordon opened a savings account with an initial deposit of $1,200.His balance will earn 2.5% simple interest overy year, Balley openeda savings account with an initial deposit of $900. Her balance willearn 3.25% interest compounded annually. The deposits were madeon the same day, and no additional money will be deposited orwithdrawn from the accounts. Which statement about the balances ofGordon's account and Balley's account at the end of 6 years is true?
Answers
Answer:
In 6 years form now, the balance in Gordon's account will be = {$1,200 x [1 + (2.5% x 6 years)]} = $1,380
his account will have earned = 2.5% x 6 years x $1,200 = $180 in interests over the six years
In 6 years form now, the balance in Bailey's account will be = $900 x (1 + 3.25%)⁶ = $1,090.39
his account will have earned = $190.39 in interests over the six years
Bailey's account earned more interest than Gordon's, even though his initial balance was much lower. This was due to higher interest rates and more important, because Bailey earned compound interest.

Mr. Doyle needs to mow his rectangular lawn that measures 23 x 25 square feet. Does he need to find the area or the perimeter of the lawn if he wants to mow the entire lawn? What is the total amount of lawn that he will mow?
Answers
Answer:
For this case Mr Doyle nees to cut his rectangular lawn and we assume that all the place is covered by lawn so then we need to find the area.
[tex]A = 23ft* 25 ft = 575 ft^2[/tex]
So then Mr Doyle need to mow 575 ft^2 in order to finish the job
Step-by-step explanation:
For this case Mr Doyle nees to cut his rectangular lawn and we assume that all the place is covered by lawn so then we need to find the area.
And the area for a rectangular shape is given by:
[tex] A = lw[/tex]
Where l is the length and w the width. If we replace the info given we got:
[tex]A = 23ft* 25 ft = 575 ft^2[/tex]
So then Mr Doyle need to mow 575 ft^2 in order to finish the job
Answer:
[tex]A = 23ft\times25 ft \\\\= 575 ft^2[/tex]
Mr Doyle need to mow [tex]575 ft^2[/tex] in order to mow the entire lawn
Step-by-step explanation:
Mr. Doyle needs to mow his rectangular lawn that measures 23 x 25 square feet.
we will have to find the area.
And the area for a rectangular lawn is Length * Breadth
A = L * B
Where l is the length and B is the width.
L = 23 square feet
B = 25 square feet
By inputting the values we get,
[tex]A = 23ft\times25 ft \\\\= 575 ft^2[/tex]
Therefore, Mr Doyle need to mow [tex]575 ft^2[/tex] in order to mow the entire lawn

Answer:
As an improper fraction: [tex]15/11[/tex]
As a mixed number: [tex]1 \frac{4}{11}[/tex]
As a decimal: 1.36
Step-by-step explanation:
[tex]3/5x - 1/3x = x - 1[/tex]
Find a common denominator between 5 and 3 (15)
[tex](3 * 3) / 15x - (1 * 5) / 15 = x - 1[/tex]
[tex]9/15x - 5/15 = x - 1[/tex]
Subtract the fractions
[tex]4/15x = x - 1[/tex]
Subtract x from both sides of the equation
[tex]-11/15x = -1[/tex]
Multiply both sides of the equation by 15/-11 to simplify
x = 15/11
Hope this helps :)
Answer:
Exact Form:
x = 15/11
Decimal Form:
x = 1.36
Mixed Number Form:
x = 1(4)/(11)
Step-by-step explanation:
(3)/(5)x-(1)/(3)=x-1
Simplify (3)/(5)x-(1)/(3)x
(4x)/(15)=x-1
Move all terms containing x to the left side of the equation.
-(11x)/(15)=-1
Multiply both sides of the equation by -(15)/(11)
-(15)/(11)(-(11)/(15))= -(15)/(11) . -1
Simplify both sides of the equation.
(15)/(11)
The result can be shown in multiple forms.
Exact Form:
x = 15/11
Decimal Form:
x = 1.36

Second day: 1.5 * 6 = 9 km
Third day: 1.333 * 6 = 8 km
Fourth day: 2.4 * 6 = 14.4 km
Sixth day: 1.666 * 6 = 10 km
on Saturday: 2.75 * 6 = 16.5 km
the average per day
(12 + 9 + 8 + 14.4 + 10 +16.5) / 6 = 11.65
