An office is planning to divide a common area into a social area and a quiet area. The quiet area takes up one-third of the space. The architect draws this plan at a scale of 1 ft.: 4 cm. What is the area of the social area on the plan?
Answer:
Let's call the total area of the common space "A". Since the quiet area takes up one-third of the space, its area is A/3.
The scale of the plan is 1 ft.: 4 cm, which means that one foot on the plan represents 4 cm in real life. So, the area of the social area on the plan is 4 times smaller than the actual area of the social space.
Therefore, the actual area of the social space is (A - A/3) = 2A/3. And the area of the social area on the plan is (2A/3) / 4.
Area of the social area on the plan is (2A/3) / 4.
Here,
Let the total area of the common space "A".
Since the quiet area takes up one-third of the space, its area is A/3.
The scale of the plan is 1 ft.: 4 cm
So,
One foot on the plan represents 4 cm in real life.
So, the area of the social area on the plan is 4 times smaller than the actual area of the social space.
Therefore, the actual area of the social space is (A - A/3) = 2A/3.
Thus the area of the social area on the plan is (2A/3) / 4.

What is congruent triangle?Two triangles are congruent if all three pairs of corresponding sides are equal. Two pairs of corresponding sides and the corresponding angles between them are equal.
here, we have,
we know that,
To identify which triangles are congruent measure the angles and sides of each of the triangles and compare them.
Meaning of congruent:
In mathematics, the word congruent is used if two figures have the same size and shape, although their orientation can be different.
Two triangles are congruent:
In the case of triangles two factors should be considered:
1) Lengths of each side are equal.
2) Angles are equal.
This means that to determine if the triangles are congruent, we must measure each side and angle and make sure these are the same in each triangle.
now, we have,
1. These two triangles have a pair of congruent sides with a congruent angle between them. Therefore, they are congruent by SAS.
If you rotate the first triangle, you'll see that it is the same as the second and, similar for 2 & 3 by AAS & SAS.

29. A racket is propelled upward from the top of a building 210 feet tall at an initial velocity of 112 feet per secon
The function that describes the height of the rocket in terms of time t is S(t) = - 16+2 + 112t + 210.
Determine the time at which the rocket reaches its maximum height.
a. 2.8 seconds
b. 3.5 seconds
C. 7 seconds
d. 5.6 secands
The time at which the rocket reaches its maximum height is 3.5 seconds. Therefore, b. is the correct answer.
What is function f(x)?An equation describing the relationship between the input (x) and the output (f(x)) is called the function f(x). Any equation that represents the connection between an input x and an output f is referred to as the function f(x) (x).
A function can be expressed as a graph or table in addition to the standard form of an equation. Functions can be stated using symbols and phrases in addition to equations. A function could be expressed, for instance, as "the square of x" or "f of x equals x squared."
Whatever form a function takes, it's critical to keep in mind that the input (x) always yields the same result (f(x)).
In the given question,
The maximum height of the rocket is achieved at the point when the velocity of the rocket is 112 feet. This can be determined by taking the derivative of the function S(t).
S'(t) = 112
Therefore, when S'(t) = 112, t = 3.5.
This means that the rocket reaches its maximum height at t = 3.5 seconds.
Therefore, the time at which the rocket reaches its maximum height is 3.5 seconds.

What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = -5x³ - 8x² - 4x + 3
g(x) = 3x³ - 2x² - 8x - 4
Now,
(f - g)(x)
= f(x) - g(x)
= -5x³ - 8x² - 4x + 3 - (3x³ - 2x² - 8x - 4)
= -5x³ - 8x² - 4x + 3 - 3x³ + 2x² + 8x + 4

D. The length is 18 inch and the width is 9 inch
D. The length is 18 inches and the width is 9 inch
What is a scale factor?
A scale factor resembles a unit scale in several ways. It is a ratio that assesses the relationship between scale and real dimensions. Because it doesn't provide any specified units, it differs.
It is given that the scale factor of the gardener is 1:15.
The dimensions of his drawing are 6 inches long by 3 inches wide.
Therefore the original dimensions are 6*15= 90 inches.
3*15= 45 inches.
The scale of his partner is 1:5.
So, we have to divide the original dimensions by 5.
The dimensions of the scale drawing are 90/5= 18 inches long
45/5=9 inches wide.
Therefore length is 18 inches and the width is 9 inches.

The price of a gallon of unleaded gas was $2.81 yesterday. Today, the price rose to $2.88. Find the percentage increase. Round your answer to the nearest tenth of a percent.
The percentage increase of the gas would be 2.5%.
How to calculate a percentage increase?We can calculate the value of the percentage increase by the following formula,
percentage increase = (final value - initial value) / initial value × 100%
As per the given question, we have
initial value = $2.81 , and final value = $2.88
Substitute the values in the above formula, and we get
percentage increase= (2.88 - 2.81 ) / 2.81 × 100%
percentage increase = (0.07) / 2.81× 100%
percentage increase = 0.0249 × 100%

First, use the equation for a hemisphere. Since a sphere's equation is [tex]\frac{4}{3}\pi r^{3}[/tex], and a hemisphere is half a sphere, we can use the equation [tex]\frac{2}{3}\pi r^{3}[/tex]. We know the radius is 6 inches, and we can approximate pi as 3.14, so now let's plug in our values:
[tex]\frac{2}{3}\ (3.14) 6^{3}=\frac{2}{3} \ (3.14)(216)= \frac{2}{3}(678.16)= 452.16[/tex]
The volume of the hemisphere is about [tex]452.16 in^{3}[/tex].
The formula for the volume of a cone is [tex]\pi r^{2}\frac{h}{3}[/tex]. Again, let's plug in our values:
[tex](3.14)(36)\frac{6}{3} =(3.14)(36)(2)=(3.14)(72)=226.08[/tex]
The volume of the cone is about [tex]226.08 in^{3}[/tex].
Subtract 226.08 from 452.16 and you get 226.08.
The volume of the remaining solid will be [tex]226.08 in^{3}[/tex].

The values and graph of the equation 3x - 2y = 6 is attached below while the slope is 3/2
What is equation of lineThe equation of a straight line can be represented in various forms. One of the most commonly used forms is the point-slope form, which is represented as:
y - y1 = m (x - x1)
where (x1, y1) is a point on the line, and m is the slope of the line, which is the rate of change of y with respect to x.
Another common form of the equation of a line is the slope-intercept form, which is represented as:
y = mx + b
where m is the slope of the line, and b is the y-intercept, which is the point where the line crosses the y-axis.
In this problem, we need to write the table of values and the find the slope of the line.
3x - 2y = 6
rewriting this equation;
2y = 3x - 6
y = 3x/2 - 3
when y = 0
0 = 3x/2 - 3
3x/2 = 3
3x = 2 * 3
3x = 6
x = 2
when x = 0
y = 3(0)/2 - 3
y = 0 - 3
y = -3
The slope of the line can be calculated using the two points from above.
slope (m) = y₂ - y₁ / x₂ - x₁
m = -3 - 0 / 0 - 2
m = 3/2
The slope is 3/2

a student committee has 6 membersâ4 undergraduate and 2 graduate students. a subcommittee of 3 members is to be chosen randomly so that each possible combination of 3 of the 6 students is equally likely to be selected. what is the probability that there will be no graduate students on the subcommittee?
The probability of choosing a subcommittee of 3 members with no graduate students is 0.2, or 20%.
The number of possible subcommittees that contain only undergraduate students can be calculated by choosing 3 members from the 4 undergraduate students. This can be done in (4 choose 3) = 4 ways.
The total number of possible subcommittees of three students that can be formed from the 6 members of the committee can be calculated by choosing 3 members from the 6 students. This can be done in (6 choose 3) = 20 ways.
Therefore, the probability that there will be no graduate students on the subcommittee is:
Number of subcommittees with only undergraduate students / Total number of possible subcommittees
= 4 / 20
= 1/5

So, the probability of choosing a subcommittee of 3 members with no graduate students is 0.2, or 20%.
