_________________
X = (-1, 2).
Y = (2, -1).
Z = (-2, -1).
_________
Dₙ ∆XYZ:
X(-1, 2) → X'(-2, 4)
Y(2, -1) → Y'(4, -2)
Z(-2, -1) → Z'(-4, -2)
______________
-2 / -1 = 2, 4 / 2 = 2.
4 / 2 = 2, -2 / -1 = 2.
-4 / -2 = 2, -2 / -1 = 2.
_______________
D₂ = (x,y) → ((2)x, (2)y).
X(-1, 2) → ((2)(-1), (2)(2)) = X'(-2, 4)
Y(2, -1) → ((2)(2), (2)(-1)) = Y'(4, -2)
Z(-2, -1) → ((2)(-2), (2)(-1)) = Z'(-4, -2)

Bliss is collecting money for a fundraiser. She starts with a $2 bronze star donation from her parents, then receives 3 equal silver star donations from her neighbors. If she ends with $18, how much money does she receive from a silver star donor?
Answers
Answer: $5.33
Step-by-step explanation:
Bliss was able to collect $18 in total.
Out of this total, she received a $2.00 bronze star donation and the rest were 3 Silver star donations.
This means that the 3 equal silver star donations added up to:
= 18 - 2
= $16.00
This means that each silver star donation was:
= Amount in total / Number of silver stars
= 16 / 3
= $5.33

Answers
three odd consecutive integers are such that 3 times the smallest is 9 more than twice the largest .find the three numbers
Answers
Answer: 17, 19, 21
Step-by-step explanation:
Three consecutive odd numbers: x, x+2, x+4 (since odd numbers occur every other number)
Just to show you that the numbers are x, x+2, and x+4, just say x is 13 then x+2 is 15 and x+4 is 17 (3 consecutive odd numbers)
Now the second equation:
3x = 2(x+4) + 9
three times smallest number (which is x) is equal to 2 times the largest number (x+4) plus 9
Now solve
3x = 2(x+4) +9
3x = 2x + 8 + 9
3x = 2x + 17
x = 17
x+2 = 19
x+3 = 21
Perform the indicated operation.

Colin invests £1100 into his bank account.
He receives 5% per year simple interest.
How much will Colin have after 3 years?
Give your answer to the nearest penny where appropriate.
£
Answers
Answer:
Colin will have $1,265 after three years.
Step-by-step explanation:
First, we find the amount of interest Colin will have by using the following formula,
simple interest = principal * interest rate * time
now that we know the formula, we substitute the numbers in.
simple interest = $1,100 * 5% * 3
since the interest rate is obviously a percentage, we have to convert it into a decimal.
simple interest = $1,100 * 0.05 * 3
now that it is a decimal, we can solve this expression.
simple interest = $1,100 * 0.05 * 3
simple interest = $55 * 3 (here, we did $1,100 * 0.05 first so that it doesn't get confusing with all the numbers, it will be easier with two final numbers)
simple interest = $165
Colin has $165 simple interest but over here asks how much she will have AFTER 3 years. think about it, can you have $165 after having $1,100 in your bank AFTER 3 years? no, so we need to add the interest by the principal by using the following formula,
total amount = principal + simple interest
now, we substitute the numbers in.
total amount = principal + simple interest
total amount = $1,100 + $165
total amount = $1,265
Therefore, Colin will have $1,265 after 3 years.

A cone shaped party hat has a radius of 3 inches and a height of 6.5 inches. Find the number of cubic units that hat occupies?
Answers
Answer:
61.25
Step-by-step explanation:
The of cubic units which hat occupies having a radius of 3 inches and a height of 6.5 inches is 61.26 cubic inches.
What is of volume of cone?Volume of cone is the amount of quantity, which is obtained it in the 3 dimensional space.
The volume of the cone can be given as,
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Here, (r) is the radius of the base of the cone and (h) is the height of the cone.
A cone-shaped party hat has a radius of r=3 inches and a height of h=6.5 inches. The amount of cubic units it occupies is equal to the volume of hat.
Thus, put the values in the above formula as,
[tex]V=\dfrac{1}{3}\pi (3)^2(6.5)\\V=\dfrac{1}{3}\pi (3)^2(6.5)\\V=61.26\rm\; in^3[/tex]
Thus, the of cubic units which hat occupies having a radius of 3 inches and a height of 6.5 inches is 61.26 cubic inches.

for what value of q is in the question -13(q+4)=7q+16
Answers
Answer:
q=-3 2/5
Step-by-step explanation:
First multiply -13 with (q+4)
-13q-52=7q+16
Now you have to change the order before = the numbers with q and after = the numbers without anything
-13q-7q=52+16
Remember that when you change positions the symbol too
Then solve it
-20q=68
Now u have to divide as i do
q=68/-20
you can simplify it
q=3 8/-20
Now divide by the greater divisor in this case is 4
q=3 2/-5
And organize it
q=-3 2/5
Never forget to do q=(answer)
