PLEASE HELP ASAP!!!!
Answer:
The correct Option is Option A
Account B because the principal of Account B is $300 and the principal for Account A is $150
Step-by-step explanation:
Interest earned from Account A = $ 4.50
Interest earned from Account B = $22.50
Time t = 18 months
Interest rate for Account A = 2%
Interest rate for Account B = 5%
We need to find which account has greater principal
The formula used to calculate principal is: [tex]Interest=Principal\times r \times t[/tex]
where r is rate and t is time
Finding Principal for Account A:
Interest earned from Account A = $ 4.50
Time t = 18 months = 1.5 years
Interest rate for Account A = 2% = 0.02
Putting values and finding Principal
[tex]Interest=Principal\times r \times t\\4.50=Principal\times0.02\times1.5\\Principal=\frac{4.50}{0.02\times1.5} \\Principal=\frac{4.50}{0.03} \\Principal=150[/tex]
So, The Principal Amount for Account A = $150
Finding Principal for Account B:
Interest earned from Account B = $ 22.50
Time t = 18 months = 1.5 years
Interest rate for Account A = 5% = 0.05
Putting values and finding Principal
[tex]Interest=Principal\times r \times t\\22.50=Principal\times0.05\times1.5\\Principal=\frac{22.50}{0.05\times1.5} \\Principal=\frac{22.50}{0.075} \\Principal=300[/tex]
So, The Principal Amount for Account B = $300
So, the correct Option is Option A
Account B because the principal of Account B is $300 and the principal for Account A is $150
Write expressions for the following scenarios.
Albert, Bill and Carl are brothers.
Bill is 4 years older than Albert.
Carl is twice the age of Albert.
Write an expression for the sum of their ages.
Answer:
flaimgo/albert
Step-by-step explanation:
Write a system of equations to describe the situation below, solve, and write as an ordered pair (with number of months as x).
Two friends, Ann and Malia, are growing out their hair. They plan to cut it off at a certain point and donate it to a charity that makes wigs for people with cancer. Ann's hair is already 23 centimeters long and grows at a constant rate of 3 centimeters per month. Malia's hair is 27 centimeters and growing at a speed of 1 centimeter per month. If the girls get their hair cut on a certain day, they will have exactly the same length to donate. How long will their hair be? How long will that take?

Ann's hair length: y = 23 + 3x
Malia's hair length: y = 27 + x
Thus: 23 + 3x = 27 + x
23 + 2x = 27
2x = 4
x = 2
Ann's hair length: y = 23 + 2(3) = 29
Malia's Hair length: y = 27 + 2 = 29
Solution: (x, y) = (2, 29)
In 2 months both Ann's and Malia's hair will be 29 centimeters long.

Let's start with Ann's hair: 23 centimeters + 3 centimeters per month
Malia's hair: 27 centimeters + 1 centimeter per month
Now we can substitute the number of months for "x"
Ann's hair length = 23 + 3x
Malia's hair length = 27 +1x
We know that we want both girls to have the same hair length at the end so we can set these two equations as equal to each other:
23 + 3x = 27 + 1x Subtract 23 from both sides
3x = 4 + 1x Subtract 1x from both sides
2x = 4 Divide by 2
x=2 Now we know it will take 2 months for their hair to be the same length!
Let's plug that in to our original equations:
Ann's hair length = 23 + 3(2) = 29 centimeters
Malia's hair = 27 + 1(2) = 29 centimeters
It will take 2 months for the girls to grow their hair to the same length of 29 centimeters.
As ordered pairs, with x as the number of months, we can use the length of the girls hair as the y value.
At 0 months, Ann's hair is 23 cm and Malia's is 27 cm so the first ordered pairs are (0, 23) and (0, 27).
At 1 month, Ann's hair grows 3 cm and Malia's grows 1 cm so the second pairs are (1, 26) and (1, 28).
Finally, at 2 months Ann's hair is at 29 cm and so is Malia's so the final ordered pair is (2, 29) for both girls.
If you were to draw these equations on a graph, (2, 29) is where the lines would intersect.

how do I solve -12+1/2x=-6
Answer:
x = 12
Step-by-step explanation:
First, eliminate the fractional coefficient 1/2, by multiplying all three terms by 2:
-24 + x = -12
Adding 24 to both sides isolates x: x = -12 + 24, or x = 12

Jaxon must sell at least 49 rolls of wrapping paper to support the robotics club fundraiser. He has already sold 24 rolls of wrapping paper. Which inequality best represents the number of rolls of wrapping paper Jaxon still needs to sell
Answer:
x≥25
Step-by-step explanation:
Step one:
given data
Jaxon must sell at least 49 rolls of wrapping paper to support the robotics club fundraiser
We are told that he has already sold 24 rolls of wrapping paper.
Step two:
let x be the number of rolls remaining to be sold,
hence,
x≥49-24
x≥25
Therefore the inequality for the situation is x≥25
which reads that x must be greater than or equal to 25
Given: WX bisects ZXY, ŽX =YX
Prove:ZXV=YXV
The required fill-in-the-blank below as:
1.) ZW ⊥ XW, ZW ⊥ WY, ∠ ZXV ≅ ∠ YXV | Given
2.) XV≅XV | Reflexive Property
3). SAS Triangle Congruence Property
What are congruent triangles?Two triangles are said to be congruent if their corresponding sides and angles are equal.
The given in question as:
WX bisects ZXY,
ŽX =YX
To prove:
△ZXV ≅ △YXV
1.) ZW ⊥ XW, ZW ⊥ WY, ∠ ZXV ≅ ∠ YXV | Given
2.) XV≅XV | Reflexive Property
According to SAS, two triangles are congruent if the two sides and the included angle of one triangle are equal to the corresponding sides and the included angle of the other triangle.
3). SAS Triangle Congruence Property
Hence, △ZXV ≅ △YXV
Thus, the required fill-in-the-blank above is in the solution.

The set of ordered pairs below represents a function.
{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}
Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.
Select all ordered pairs that could be used to show that this claim is incorrect.
(–9, –6)
(1, 12)
(–10, –10)
(4, 7)
(–5, 1)
Given:
The set of ordered pairs below represents a function.
{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}
Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.
To find:
All the ordered pairs that could be used to show that this claim is incorrect.
Solution:
We need to find the ordered pairs that can be replaced with (6,-10) and for which the set is not a function.
A relation is called function if there exist a unique output for each input.
If (-9,-6) is replaces with (6,-10), then the set has two outputs y=1 and y=-6 for x=-9. So, the claim is incorrect.
If (1,12) is replaces with (6,-10), then the set has two outputs y=12 and y=3 for x=1. So, the claim is incorrect.
If (-10,-10) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.
If (4,7) is replaces with (6,-10), then there exist unique output for each input. So, the claim is correct.
If (-5,1) is replaces with (6,-10), then the set has two outputs y=1 and y=2 for x=-5. So, the claim is incorrect.
Therefore, the correct options are (a), (b) and (e).
