if one inch represents 14 feet how many inches would you use to make a scale drawing of a building that is 199 feet
Answer:
14.21 inches
Step-by-step explanation:
Given
1 inch = 14 feet
Required
Find the equivalent of 199 feet
Write out the given expression;
1 inch = 14 feet
Let x represent the equivalent of 199 feet in inches; Such that:
x = 199 feet
Write out both expressions
1 inch = 14 feet
x = 199 feet
Using cross multiplication; both expressions become
x * 14 feet = 199 feet * 1 inch
Divide both sides by 14 feet
[tex]\frac{x * 14 feet}{14 feet} = \frac{199 feet * 1 inch}{14 feet}[/tex]
[tex]\frac{x * 14}{14} = \frac{199* 1 inch}{14}[/tex]
[tex]\frac{14x}{14} = \frac{199* 1 inch}{14}[/tex]
[tex]x = \frac{199* 1 inch}{14}[/tex]
[tex]x = \frac{199inch}{14}[/tex]
[tex]x = 14.2142857143inch[/tex]

A swim team must be chosen from 10 candidates. What is the greatest number of different four-person teams that can be chosen?
Answer:
210 combinations
Step-by-step explanation:
The total number of candidates given = n = 10
The number of candidates to be chosen = r = 4
As in this, the sequence of the chosen candidates doesn't matter, we can use Combination to find the solution.
C(n,r) = n! / (n-r)! (r)!
where n = 10 and r = 4
C(10,4) = 10! / (10-4)! (4)!
C(10,4) = 10! / 6! 4!
C(10,4) = (10·9·8·7·6·5·4·3·2·1) / (6·5·4·3·2·1)(4·3·2·1)
C(10,4) = (10·9·8·7) / ((4·3·2·1))
C(10,4) = 210 combinations

Which is the graph of the linear inequality 2x – 3y < 12?
B
Answer:
C.
Step-by-step explanation:
Given
2x - 3y < 12
Required
Find the graph it represents
we start by solving for the x and y intercepts;
Let x = 0
2x - 3y < 12 becomes
2(0) - 3y < 12
0 - 3y < 12
-3y < 12
Divide both sides by -3
-3y/3 < 12/-3
y > -4
Let y = 0
2x - 3y < 12 becomes
2x - 3(0) < 12
2x - 0 < 12
2x < 12
Divide both sides by 2
2x/2 < 12/2
x < 6
So, we have
x < 6 and y > -4
This implies that the graph is bound by the region where the values of x is less than 6 and the values of y is greater than -4
From the list of given options,only option C answers this question. The dotted lines actually represent inequalities
Choose the slope and y-intercept that corresponds with the graph.
Answer:
slope 3, y intercept 4
Step-by-step explanation:
The y intercept is where it crosses the y axis
It crosses at y=4
The slope is positive since it goes from bottom left to top right
The slope is up 3 over 1 so it is 3/1 = 3
For all 5 problems in this assignment, use the following functions:

h(x) = 3x2 - 2x + 5
Match the function with its value.
(f+g)(x)
Choose...
(f*h)(x)
Choose...
h[f(5)] -g[h(1)] Choose...
Answer:
1.) x^2 + 3x
2.) 3x^2 - 3x
3.) 278
Step-by-step explanation:
You are given the following functions:
f(x) = x + 5
g(x) = x2 + 4x + 5
h(x) = 3x2 - 2x + 5
1.) To match the function with its value,
(f+g)(x) = f(x) + g(x)
Substitutes for the two functions
X + 5 = x^2 + 4x + 5
Collect the like terms and equate them to zero
X^2 + 4x - x + 5 - 5
X^2 + 3x
Therefore, (f+g) (x) = x^2 + 3x
2.) (f*h)(x) = f(x) × h(x)
x + 5 = 3x^2 - 2x + 5
Collect the like terms
3x^2 - 2x - x + 5 - 5
3x^2 - 3x
Therefore, (f×h)(x) = 3x^2 - 3x
3.) h[f(5)] -g[h(1)]
First find f(5)
That is, substitute x for 5 in f(x)
f(5) = 5 + 5 = 10
Also, do the same for h(1)
h(1) = 3(1)^2 - 2(1) + 5
h(1) = 3 - 2 + 5 = 6
h[f(5)] - g[h(1)]
= 3(10)^2 - 2(10) + 5 - (6)^2 + 4(6) + 5
= 300 - 20 + 5 - 36 + 24 + 5
= 334 - 56
= 278
Therefore, h[f(5)] - g[h(1)] = 278
Which transformations can be used to carry ABCD onto itself? The point of
rotation is (3,2). Check all that apply.
Answer:
A and B
Step-by-step explanation:
For A, y=2 is the axis of vertical symmetry, meaning a reflection would map the shape onto itself.
For B, x=3 is the axis of horizontal symmetry, meaning a reflection would map the shape onto itself.
For C, a rotation of 90 degrees would make the shape taller vertically and shorter horizontally, therefore it would be wrong.
For D, a translation two units down would move all points down, even though some would need to go up, therefore it would be wrong.

The true statement concerning the exterior angles of a triangle is that it forms a linear pair with one of the interior angles of the triangle.
What is the exterior angle of a triangle?The exterior angle theorem asserts that the total of the opposing and non-adjacent internal angles of a triangle equals the measurement of each exterior angle.
When one side of a triangle is stretched in such a way that a non-straight angle is produced exterior of the triangle but near to an interior angle, an external angle is formed.
Therefore, we can conclude that the true statement concerning the exterior angles of a triangle is that it forms a linear pair with one of the interior angles of the triangle.

A special type of password consists of 3 different letters of the alphabet, and the two different numbers, where each letter and each number is used only once. How many different possible passwords are there?
Answer:
There can be 14,040,000 different passwords
Step-by-step explanation:
Number of permutations to order 3 letters and 2 numbers (total 5)
(AAANN, AANNA,AANAN,...)
= 5! / (3! 2!)
= 120 / (6*2)
= 10
For each permutation, the three distinct (English) letters can be arranged in
26!/(26-3)! = 26!/23! = 26*25*24 = 15600 ways
For each permutation, the two distinct digits can be arranged in
10!/(10-2)! = 10!/8! = 10*9 = 90 ways.
So the total number of distinct passwords is the product of all three permutations,
N = 10 * 15600 * 90 = 14,040,000

The two cylinders are similar. Find the surface area of the smaller cylinder. Round your answer to the nearest hundredth.
A. 942.48 cm²
B. 376.99 cm²
C. 565.49 cm²
D. 226.19 cm²
Answer:
D
Step-by-step explanation:
To first tackle this question, use similarity ratio, where the missing diameter is d. 10/15 = d/9 which can be simplified into d = 6. Then use the surface formula
2πrh + 2πr². Then, since the radius is 0.5d, the radius or r is 3. Then, plus in values and simplify to get 226.19cm².
Filipe was playing with a triangle on a coordinate plane. The triangle's area is 24 square units. The largest circle he can fit in the triangle is centered at (0,0) and passes through the point (1.2,1.6). Approximately what percentage of the triangle does the circle cover?
Answer:
52.36%
Step-by-step explanation:
I did this problem on a test
52.33% is the percentage of the triangle does the circle cover.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Area of triangle = 24 sq units
Center of Circle is at (0, 0) and the circle passes through (1.2, 1.6).
We need to find the percentage of triangle covered by circle.
we need to find the area of circle.
To find the area of circle, we need the radius of circle.
Radius of circle is the distance between the center of circle and any point that lies on the periphery of the circle.
Radius = =√(1.2-0)²+(1.6-0)²
=2 units
Now, area of circle is given by the formula:
Area = πr²=3.142×4=12.56 sq units
Percentage of Triangle covered:
Area of circle/Area of triangle × 100
12.56/24× 100
52.33%
Hence, 52.33% is the percentage of the triangle does the circle cover.

FEDC similar UTSVFEDC similar STUV****There are a lot but the first letter of the first polygon corresponds with the first letter of the second polygon and so on. That is the only way this statement is true. There are about a 96 different combinations for this so any one would work.
The similarity ratio is the same thing as asking "what value would make the first polygon congruent to the second"? In this case 1(x) = 4, x = 4. Therefore the ratio is 4, or 4/1 (if asked can also be written as 4:1. THE ORDER IS ALSO VERY IMPORTANT.
Which simplified fraction is equivalent of 5.6 3/15 14/25 5/6 14/250
Answer:
Thus, 28/5 is equivalent of 5.6
Step-by-step explanation:
Given
Number is 5.6
it is in decimal form.
The first number after decimal represent the tenth of number
The Second number after decimal represent the hundredth of number
and similarly we can define thousandth of a number.
Step to write decimal number in fractional form is (say a.bcd
write the full number without decimal
so number will be
abcd
divide the number by 1
abcd/1
now count the number of digit after decimal and put as many 0's after 1
there are three digits after decimal, we will put three digit after 1 in denominator
thus number in fraction is
abcd/1000
_________________________________________________
Given number is 5.6
hence writing it in fractional form as explained above
5.6 = 56/10
56 = 28*2
10 = 2*5
5.6 = 56/10 = 2*28/2*5 = 28/5
Thus, 28/5 is equivalent of 5.6
