(SAT Prep) In the figure, what is the ratio of the area of square KLMN to the area of △LOK?
Answer:
D. 2:1
Step-by-step explanation:
Imagine a line that is parallel to the top of the square that passes thru point O
that would make two more triangles. The two in the top would be equal and the two in the bottom would be equal.
Therefore, the area of square KLMN is two times the area of triangle LOK
Answer:
D. 2:1
Step-by-step explanation:
Area of square KLMN = LM*LKArea of triangle LOK= 1/2*LM*LKratio of areas:
LM*LK : 1/2 LM*LK= 2:1Answer: 2:1 option D

Translate the phrase into an algebraic three dollars more than twice the cost of a bowl of soups 2+3
3(2c)
3+2c
2+2c
Answer:
3+2c
Step-by-step explanation:
To translate the phrase into an algebraic expression, you have to analyze the information provided. Three dollars more than twice the cost of a bowl of soups means that given that c is the costs of a bowl of soup, you have to multiply c for 2 as the phrase says twice the cost. Also, it says three dollars more which means that you have to add 3. According to this, the expression is: 3+2c.

Zack needs $299.99 to buy the new bike he wants. He has saved $150 so far toward the new bike. From this week on, he will save $12.50 per week toward the new bike. Ten weeks from now, how much more money will he still need to save to buy the bike?
$24.99
$29.99
$127.49
$137.49
Answer:
The answer is $24.99
The solution is Option A.
The equation of line is y = 12.5x + 150 , where x is the number of weeks
The amount Zack needs after 10 weeks to buy the bike is $ 24.99
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
The price of the bike Zack needs to buy = $ 299.99
The initial amount with Zack = $ 150
The amount Zack saves in a week = $ 12.50
The number of weeks = x
The amount Zack saves in x weeks = 12.5x
So , the total amount with Zack after x week is given by the equation ,
Total amount with Zack after x week y = amount Zack saves in x weeks + initial amount with Zack
Substituting the values in the equation , we get
Total amount with Zack after x week y = 12.5x + 150
Now , after 10 weeks , the amount with Zack is
Substitute the value of x as 10 in the equation , we get
y = 12.5x + 150
y = 12.5 ( 10 ) + 150
y = 125 + 150
y = $ 275
Now , the amount left to buy the bike = price of the bike Zack needs to buy - amount with Zack after 10 weeks
Substituting the values in the equation , we get
Amount left to buy the bike A = $ 299.99 - $ 275
Amount left to buy the bike A = $ 24.99
Therefore , the value of A is $ 24.99
Hence , the amount Zack needs is $ 24.99

Megan has two boxes with the dimensions shown. She wants to use the box with the greater volume to ship a gift to her friend. Which box should Megan use? Explain.
Answer:
384 3/4
341 1/4
box A
Step-by-step explanation:
The volume of the box is given by the formula:
Volume = length * width * height
The volume of the box A is:
Volume_A = 9.5 * 3 * 13.5 = 384.75 cm3 = 384 3/4 cm3
The volume of the box B is:
Volume_B = 10 * 3.25 * 10.5 = 341.25 cm3 = 341 1/4 cm3
The volume of the box A is greater than the volume of the box B, so Megan should use the box A

Identify the graph and describe the solution set of this system of inequalities.
y> fx+5
Answer:
What does the graph look like
Step-by-step explanation:
The inequality given is y> fx+5, if we plot the graph of the two inequalities, the graph of the inequalities will never meet at any point.
What is inequalities?In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal symbol ()" to indicate that two values aren't equal. But several inequalities are utilised to compare the numbers, whether they're less than or higher than.
The different inequality representations, properties, and methods for resolving linear inequalities throughout one variable or two variables will all be covered in this article along with examples. The inequality given is y> fx+5, if we plot the graph of the two inequalities, the graph of the inequalities will never meet at any point.
Therefore, the inequalities have no solution since their graph does not intersect or overlap.

Irrational numbers (picture provided)
Answer:
C would be irrational.
Step-by-step explanation:
Irrational means that you cannot make a distinct ratio with the number. One of the more famous irrational numbers are π. You cannot make π into a fraction with whole numbers for a numerator and denominator.
Other examples of irrational numbers are square roots that are not perfect square roots. C is not a perfect square so it is irrational.

The amount of money in Alexander’s account is, = 4000 − 70, where is the amount in dollars and is the time in weeks.
a) Which variable is independent and which is dependent?
Answer: Dependent is -70x and independent is 4000
b) In which week will there be $1701 in the account?
Answer:
y=4000-70(x)
1701=4000-70(x)
-70x=1701-4000
-70x= -2299
x=-2299/-70
x=2299/70
x=32.843
x=33
c) How much will the amount in Alexander’s account change if the time increases by 15 weeks?
Answer:
y=4000-70(x)
y=4000-70(15)
y=2950
Answer:
yes you are correct
Step-by-step explanation:
The answers are a) y is the dependent variable, x is the independent value. b) 33 weeks and c) $2950
What are dependent and independent variables?The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.
Given that, The amount of money in Alexander’s account is, y = 4000 − 70x, where y is the amount in dollars and x is the time in weeks.
a) Here, y is the dependent variable as it depends on the value of x, and x is the independent value.
b) We have, total amount = $1701
Therefore, put y = $1701
$1701 = 4000 − 70x
70x = 2999
x = 32.84 ≈ 33 weeks
c) In 15 weeks the amount will be =
y = 4000 - 70(15)
= $2950
Hence, the answers are a) y is the dependent variable, x is the independent value. b) 33 weeks and c) $2950

1) Find the length of point A(-3,1) and B(2,6). Leave your
answer in RADICAL FORM ONLY.
Answer: The length of point A(-3,1) and B(2,6) is [tex]5\sqrt{2}\text{ units}[/tex] .
Step-by-step explanation:
We know that the distance between the two points (a,b) and (c,d) is given by :-
[tex]d=\sqrt{(a-c)^2+(b-d)^2}[/tex]
Given points = A(-3,1) and B(2,6)
Therefore the distance between the points A(-3,1) and B(2,6) is given by :-
[tex]d=\sqrt{(-3-2)^2+(1-6)^2}\\\\\Rightarrow\ d=\sqrt{(-5)^2+(-5)^2}\\\\\Rightarrow\ d=\sqrt{25+25}\\\\\Rightarrow\ d=\sqrt{50}\\\\\Rightarrow\ d=\sqrt{25\times2}\\\\\Rightarrow\ d=\sqrt{5^2\times2}\\\\\Rightarrow\ d=5\sqrt{2}\text{ units}[/tex]
Hence, the length of point A(-3,1) and B(2,6) is [tex]5\sqrt{2}\text{ units}[/tex] .
