Solve for w.
0.43 +2.7w = 3.7w - 0.47
Answer:
w = 0.9
Step-by-step explanation:
What I did is I subtracted 2.7 from 3.7 bc it was the least number and that gave me 1 so that left me with 0.43 = w - 0.47. Then I added 0.47 to 0.43 and that gives me 0.9 which would be the answer

Alexander is drawing a map of the Federal Triangle in Washington, D.C. The actual Federal Triangle has a base of 3000feet and height of 1200 feet. Alexander needs his drawing to fit on his paper, so he decides to make the base of his triangle 10 inches.
What scale is Alexander using?
The scale of the drawing is 1 inch represents 300 feet .
What is the scale of the drawing?A scale drawing is a smaller image of a larger diagram or object in terms of dimensions. The scale drawing is usually reduced at a constant dimension.
In order to determine the scale of the drawing, divide the base of the actual Federal triangle by the base of the drawing.
Scale of the drawing = original dimensions / dimensions of the scale drawing
3000 / 10 = 300
1 inch represents 300 feet
1 inch : 300 feet
The scale of a drawing is usually written in this format - one a colon (:), the result of the division of the original dimension and the dimension of the scale.

The equation of the line perpendicular to the given line and that passes through the point is x + 3y = 6
From the question, we are to determine the equation of the line that is perpendicular to the given equation.
A line perpendicular to another has a slope that is the negative reciprocal of the slope of the other line.
That is,
If m₁ is the slope of one of the lines
and m₂ is the slope of the other line
Then,
m₁ = -1/m₂
First, we will determine the slope of the given line
The equation of the given line is
y = 3x - 9
Compare the equation to the general form of the equation of a straight line
y = mx + b
Where m is the slope
and b is the y-intercept
By comparison,
m = 3
∴ The slope of the given line is 3
Thus,
The slope of the line that is perpendicular to this line is -1/3
Now,
To determine the equation this line,
We have that the line passes through the point (3, 1)
Using the point-slope form of the equation of a straight line,
y - y₁ = m(x - x₁)
m = -1/3
x₁ = 3
y₁ = 1
Putting the parameters into the equation,
y - 1 = -1/3(x - 3)
Expressing the equation in standard form
3(y -1) = -1(x - 3)
3y - 3 = -x + 3
3y + x = 3 + 3
x + 3y = 6
Hence, the equation of the line perpendicular to the given line and that passes through the point is x + 3y = 6

Given the algebraic expression ----- create an equivalent expression.
The equivalent expression of (64x^2/3)^-1/3 is 1/(4x^1/9)
What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
What are rational expressions?Rational expressions are expressions that are represented by the quotient of two polynomials or radicals.
This means that, a rational expression is represented by a fraction whose numerator and denominator are polynomials or radicals
How to determine the equivalent expression?The expression is given as
(64x^2/3)^-1/3
Evaluate the product of the exponents
So, we have
(64x^2/3)^-1/3 = 64^-1/3 * x^(2/3*-1/3)
Evaluate the product of the exponents
So, we have
(64x^2/3)^-1/3 = 64^-1/3 * x^-1/9
Evaluate the exponent
So, we have
(64x^2/3)^-1/3 = 1/4 * x^-1/9
Evaluate the product
So, we have
(64x^2/3)^-1/3 = 1/4x^-1/9
Rewrite as
(64x^2/3)^-1/3 = 1/(4x^1/9)

Use that formula. The answer should be -3/0 which doesn't make sense. Are you sure you have your x values correct? Since in that case, it would be a straight line and the equation for that would be x = 6 since it is a straight line up with no y-intercept.
The graph below describes the journey of a train between two cities.
a) Work out the
acceleration, in km/h²,
in the first 15 mins
b) Work out the distance
between the two cities.
c) Work out the average
speed of the train during
the journey.
The acceleration in first 15 minutes = 200 km/h²
The distance between the two cities = 125 km
Average Speed of train during the journey = 62.5 km/hr
According to the given question:
Each block of horizontal is 1/8 hr = 7.5 min
Each block of vertical is 10 km/hr
Time Velocity (km/hr)
0 Min ( 0 hr) 0
15 Min (1/4 hr) 50
45 Min (3/4 hr) 50
60 MIn ( 1 hr) 100
90 Min ( 3/2 hr) 100
120 Min ( 2hr) 0
The acceleration in first 15 minutes = (1/4 hr) = (50 - 0)/(1/4 - 0) = 50/(1/4)
= 200 km/h²
The distance between the two cities =
= (1/2)(0 + 50)(1/4 - 0) + 50 * (3/4 - 1/4) + (1/2)(50 + 100)(1 - 3/4) + 100 * (3/2 - 1) + (1/2)(100 + 0)(2 - 3/2)

Distance between two cities = 125 km
Average Speed of train during the journey = 125/2 = 62.5 km/hr

Step-by-step explanation:
The Brandywine Dance Team is buying equipment and T-shirts. The equipment costs $356 and the T-shirts cost $12 each. The team spent a total of $644
The number of T-shirts bought by the Brandywine Dance Team is 24.
How is the number of T-shirts determined?The number of the T-shirts that the Brandywine Dance Team purchased is determined using basic mathematical operations of division, subtraction, addition, and multiplication.
First, the cost of the equipment is subtracted from the total cost spent by the team. The remainder refers to the cost of the T-shirts. Since one T-shirt costs $12, the total quantity of T-shirts bought is 24.
Data and Calculations:The total amount spent = $644
The cost of the equipment = $356
The remainder after the equipment = $288 ($644 - $356)
Unit cost of T-shirts = $12
The number of T-shirts bought = 24 ($288/$12)
