Answer:
The answer is 400
Step-by-step explanation:
Percent is to 100 as part is to whole.
In this case we have no whole but we have a part, and we have a percentage. 100% is equal to the whole so, 300 divided by 4 is 75 and what you do on the top is what you do on the bottom; 100x4=400

Step-by-step explanation:
Look at where the decimal is placed and the value of the numbers
one line passes through (-3, -1) and (2,4) another passes through points (2, -6) and (7, -1). are the lines parallel, perpendicular, or neither?
Answer:
Since they both have the same slope, they are Parallel.
Step-by-step explanation:
We will have to calculate slope for this equation using this formula:
[tex]\frac{y2-y1}{x2-x1}[/tex]
For line 1 our points are:
(-3,-1) and (2,4)
Substitute:
[tex]\frac{4+1}{2+3}[/tex]
[tex]\frac{5}{5}[/tex]
The slope for the first line is 1.
For line 2 our points are:
(2,-6) and (7,-1)
Substitute:
[tex]\frac{-1+6}{7-2}[/tex]
[tex]\frac{5}{5}[/tex]
The slope for this equation is 1.
For these lines to be parallel, they would need their slopes to be the same.
For these lines to be perpendicular, they would need to be opposite reciprocals.
Since they both have the same slope, they are Parallel.
Answer:
Parallel
Step-by-step explanation:
(-3, -1) and (2,4) -
First find the slope of the line using the slope formula [tex]\frac{y2-y1}{x2-x1}[/tex] : [tex]\frac{4-(-1)}{2-(-3)}[/tex]
Add the numbers : [tex]\frac{5}{5}[/tex]
Simplify: 1
Using one of the given ordered pairs find the y-intercept: 4 = 1(2) + b
Caluclate the product : 4 = 2 + b
Move the variable to the left-hand side and change its sign: -b = 2 - 4
Calulate the diffrence and change the signs: b = 2
Using the slope and y- intersept creat your equation : y = 1x + 2
(2, -6) and (7, -1)-
First find the slope of the line using the slope formula [tex]\frac{y2-y1}{x2-x1}[/tex] : [tex]\frac{-1-(-6)}{7-2}[/tex]
Add the numbers : [tex]\frac{5}{5}[/tex]
Simplify: 1
Using one of the given ordered pairs find the y-intercept: -6 = 1(2) + b
Caluclate the product : -6 = 2 + b
Move the variable to the left-hand side and change its sign: -b -6 = 2
Calulate the sum and change the signs: b = -8
Using the slope and y- intersept creat your equation : y = 1x + -8
Parallel lines have the same slope and different y-intercepts

1) Is the solution to -2.7 + x= -3.5 positive or
negative.
Answer:
positive because two negatives make a positive and the answer is not positive.
The solution of the expression -2.7 + x =-3.5 is -0.8 and is negative.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given expression is -2.7 + x= -3.5. The value of x will be calculated as,
-2.7 + x =-3.5
x = -3.5 + 2.7
x = -0.8
Therefore, the solution of the expression -2.7 + x =-3.5 is -0.8 and is negative.

can someone please help me (: The graph shows the relationship between the United States dollar and the euro, the currency of the European Union, in December 2011. Part B: Justify why the relationship shown in the graph is a proportional relationship. *
Answer:
Step-by-step explanation:
Let the equation of the line representing relation between the euros and dollars is,
E = mD + b
Where 'E' = Number of euros
D = Number of dollars
m = slope of the line
b = y-intercept
Slope of a line which passes through two points (120, 90) and (400, 300) will be,
m = =
m = 0.75
Equation of the line passing through (120, 90),
90 = 0.75(120) + b
b = 90 - 90 = 0
Therefore, equation of the line will be,
E = mD
E ∝ D
Here m = Proportionality constant
And the relation between the numbers of Euros and US dollars is a proportional relationship.
how to solve for the maximum profit if a function is given:)
Answer: There are two ways to find maximum profit: with a graph, or with calculus.
Graphically, you’re looking for a global maximum.
A global maximum is the maximum over the entire range of the what is a function. On a graph, that’s the highest peak.
Local maximums happen at inflection points (where the graph changes direction).
At the maximum of a function, the gradient or slope of the function is zero. With calculus, you can find the derivative of the function to find points where the gradient (slope) is zero, but these could be either maxima or minima.
If the slope is increasing at the turning point, it is a minimum.
If the slope is decreasing at the turning point, then you have found a maximum of the function.

How many boxes with a Length/Width/Height of 1/4, 1/4, and another 1/4 would fit into a box with a Length/Width/Height of 3 1/4, 3, and 3 3/4?
9514 1404 393
Answer:
2340 small boxes
Step-by-step explanation:
Each unit of measure used for the large box will contain 4 of the smaller boxes. So, in terms of small boxes, the dimensions of the larger box are ...
(3 1/4)/(1/4) = (13/4)/(1/4) = 13 . . . length
3/(1/4) = (12/4)/(1/4) = 12 . . . . . . . width
(3 3/4)/(1/4) = (15/4)/(1/4) = 15 . . . height
Then the number of small boxes that would fit is ...
length × width × height = 13×12×15 = 2340
2340 cubes of size 1/4 will fit into the larger box.

1. Find the distance from point P to QS
SHOW ALL OF YOUR WORK
S(0,8)
R(-3,5)
Q(-5,3)
P(1, 1)
Answer:
5.7 units
Step-by-step explanation:
The distance from point P to QS is the distance from point P (1, 1) to the point of interception R(-3, 5).
Use distance formula to calculate distance between P and R:
[tex] PR = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] P (1, 1) = (x_1, y_1) [/tex]
[tex] R(-3, 5) = (x_2, y_2) [/tex]
Plug in the values into the formula.
[tex] PR = \sqrt{(-3 - 1)^2 + (5 - 1)^2} [/tex]
[tex] PR = \sqrt{(-4)^2 + (4)^2} [/tex]
[tex] PR = \sqrt{16 + 16} [/tex]
[tex] PR = \sqrt{32} [/tex]
[tex] PR = 5.7 units [/tex] (to nearest tenth)
