Marsha has $400 in a savings account. The interest rate is 5% per year and is not compounded. How much will she have in total in 1 year?
The total amount in the account after 1 year will be $420
Based on the information given, the following can be deduced:
Principal = $400
Interest rate = 5%
Time = 1 year
Therefore, the simple Interest will be:
= PRT/100
= ($400 × 5 × 1)/100
= $2000/100
= $20
Therefore, the amount will then be:
= Principal + Interest
= $400 + $20
= $420
Therefore, the total amount is $420

Eric traveled to three cities on a single highway. The distance from his original location to the first city was 100 miles more than the distance from the first city to the second city. The distance from the second city to the third city was 10 miles less than the distance from the first city to the second city. If the distance from his original location to the first city and the distance from the second city to the third city were the same, what was the total distance Eric traveled?
Answer:
Well think about it, the key words there are more than and less than so if he traveled let's say from his house until the first city that's 100 miles for the first one and then they say that he traveled 10 miles less than the distance from the first city until the second city. The total distance is 280 because if you read the very last sentence it says that from the original distance from the first city is about 100 miles and then it says if the the distance from the second city to the third city was the same that means that the equation goes like this: (90*2)+100 and in order to get this correctly you must do P.E.M.D.A.S which is parenthesis, exponents, multiplying, dividing, adding and subtracting so there you go.

Which expression is a perfect square?
A. x² - 4x + 4
B. x2 - 4x - 4
C. 12 - 9x + 9
D. 12 - 9x – 9
Answer: Choice A
========================================================
Explanation:
A perfect square trinomial is of the form
(m+n)^2 = m^2 + 2mn + n^2
We can see why this works through use of the FOIL rule.
So the first and last terms must be perfect squares, and they must be positive. This rules out choices B and D since we have -4 and -9 as those last terms being negative.
Choice C is ruled out because the middle coefficient -9 isn't correct. The middle coefficient must be some even number since 2 is a factor of 2mn.
This leaves choice A. We can do a bit of trial and error to find that
(x-2)^2 = x^2 - 4x + 4
showing that choice A is a perfect square trinomial.
Answer:
A) x² - 4x + 4
Step-by-step explanation:
Given the following special factoring formulas on perfect square trinomials:
u² + 2uv + v² = (u + v)²
u² - 2uv + v² = (u - v)²
Apply these concepts on the given set of equations to see which special factoring formulas apply on the given options. I will only work on one of the given options, and you could apply these same techniques on the other ones to compare the results with your calculations.
To find the binomial factors of quadratic equations, you must find factors with product uv, and sum v.
In Option A: x² - 4x + 4
Right off the bat, it seems like the difference of squares may apply to this equation. You must find the factors that will product of 4 and a sum of -4.
The possible factors are:
product uv: -2 × -2 = 4,
sum v : -2 + -2 = -4
Hence, the binomial factor of x² - 4x + 4 = (x - 2)²
If you expand this binomial through FOIL method:
(x - 2)(x - 2) = x² - 2x - 2x + 4 = x² - 4x + 4
This means that the trinomial x² - 4x + 4 produces a perfect square binomial factors of (x - 2)².
Therefore, the correct answer is Option A) x² - 4x + 4.

Given the system of equations, what is the solution?
2x + y = 7
2x - 3y = -1
Answer:
[tex](\frac{5}{2}, 2)[/tex]
Step-by-step explanation:
Hi there!
We are given this system of equations:
2x + y = 7
2x - 3y = -1
And we want to find the solution
There are multiply ways to solve systems of equations, but let's solve this one by elimination, where we will add the two equations together to clear one of them, solve for the un-cleared variable, and then use the value of the un-cleared variable to solve for the cleared one
Before clearing a variable, we need to make sure that the signs on the variables are opposites; for example, -3 and 3, which will add together to get 0
We can multiply the equations beforehand if needed in order to manipulate the numbers.
For example, we can multiply the second equation by -1 in order to switch the signs of each number in that equation:
-1(2x-3y=-1)
-2x+3y=1
Now the signs in front of x are 2 and -2, so we can add the equations together to clear them:
2x + y = 7
-2x + 3y = 1
Add the equations together
4y = 8
Divide both sides by 4
y=2
Now let's use 2 as y to solve for x
In the first equation, substitute 2 for y:
2x + 2 = 7
Subtract 2 from both sides
2x = 5
Divide both sides by 2
[tex]x=\frac{5}{2}[/tex]
As a point, the answer is [tex](\frac{5}{2}, 2)[/tex]

Answer:
Jon is now 10% faster.
Step-by-step explanation:
Since Jon's average speed was 20 MPH and his new average speed is now 22 MPH, we can see that his speed increased by 2 MPH. Now we know that, we would now do 2÷20 = .1
10% is the percent form of 0.1

Ox= 15, y= 12
Ox= 14, y= 11
Ox=14, y = 12
Ox= 15, y= 11
Answer:
x=15,y=12
Step-by-step explanation:
Alternate angles are those angles that are on the opposite side of the parallel lines transverse with a line touching both parallel lines.
The value of x and y are 15 and 12.
x = 15
y = 12
Option A is the correct answer.
What are corresponding angles?The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.
Corresponding angles are equal.
We have,
The figure contains four angles.
62 and (4x + 2) are alternate angles.
12y and 144 are alternate angles.
We know that alternate angles are equal.
So,
62 = 4x + 2 ____(1)
12y = 144 _____(2)
From (1) we get,
62 = 4x + 2
Subtract 2 on both sides.
62 - 2 = 4x + 2 - 2
60 = 4x
Divide both sides by 4.
4x = 60
x = 60/4
x = 15
From (2)
12y = 144
Divide both sides by 12.
y = 144/12
y = 12
Thus,
The value of x and y are 15 and 12.
x = 15
y = 12
Option A is the correct answer.
