A rectangle has an area of 228 ft and a length that measures 12ft find the perimeter
The area of a rectangle is the width times the length:
[tex] A = w\cdot l \iff 228 = w\cdot 12 \iff w = \dfrac{228}{12} = 19 [/tex]
The perimeter is twice the sum of the dimensions:
[tex] 2p = 2(12+19) = 2\cdot 31 = 62 [/tex]
The perimeter of the rectangle with dimensions 19 ft*12 ft comes to be 62 square feet.
Suppose the breadth of the rectangle is x.
What is the perimeter of a rectangle?The perimeter of a rectangle is the sum of all its sides i.e. the sum of two lengths and two breadths.
If length and breadth are a and b respectively then perimeter =2(l+b).
According to the question
Length =12 ft
Area=228 square ft
So, length * breadth = 228
[tex]12x =228[/tex]
[tex]x=\frac{228}{12}[/tex]
x=19
So, breadth of the rectangle =19 ft
So, perimeter = 2(12+19) = 62 square feet.
Hence, the perimeter of the rectangle with dimensions 19 ft*12 ft comes to be 62 square feet.

What is the length of the hypotenuse of the right triangle defined by the points (–3, –1), (1, –1), and (1, 2)?
First we have to see which is the right angle. This triangle has its legs oriented parallel to the axes. (-3,-1) and (1,-1) form the horizontal leg, (1,-1) and (1,2) the vertical leg.
So the right angle vertex is (1,-1) and the hypotenuse endpoints are (-3,-1) and (1,2)
The length is given by
[tex]d = \sqrt{ (1 - -3)^2 + (2 - -1)^2} = \sqrt{4^2+3^2}=\sqrt{25} = 5[/tex]
This is a 3/4/5 right triangle.

Given one factor of the polynomial, factor the polynomial completely.
16. f(x)=x^3-4x^2-7x+10;x-5
17. g(x)=2x^3+3x^2-23x-12;2x+1
Use synthetic division to solve these problems
5 | 1 -4 -7 10
| v 5 5 -10
1 1 -2 0
This leads to x^2+x-2
Next we find what adds to 1 and multiplies to -2
The factors of f(x) are 2 and -1, written out as (x+2) and (x-1)
-1/2 | 2 3 -23 -12
| v -1 -1 12
2 2 -24 0
This leads to 2x^2+2x-24
Next, multiply the 2 from the a value (since a is the value with x^2 and c is the value without any x) with -24, which is -48
Now find what adds to 2 and multiplies to -48
The values for this are 8 and -6, but keep in mind, when multiplying the value of a by c, you now have to add the values in place of what you tried adding it to, this time in the problem we found using synthetic division, in this case the 2 in the b value (the middle of the equation, or the value with only one x)
2x^2+8x-6x-24
When group factoring, you'd get 2x(x+4) -6 (x+4)
So, the factors of g(x) are (x+4) and (2x-6)

B. 16.04 units
C. 8.02 units
D. 8.31 units
why hello there
Your answer is C 8.02
If u can please mark me as brainliest i really want genius!
Answer:
The correct option is C.
Step-by-step explanation:
Given information: In circle O, AB=8.02, the distance of cord AB from the center is 8.31, the distance of cord CD from the center is 8.31.
According to the chords equidistant from the center theorem, if two cords are equidistant form the center, the length of both cords are equal.
Since the cords AB and CD are equidistant form the center O, therefore
[tex]AB=CD[/tex]
[tex]8.02=CD[/tex]
The length of cord CD is 8.02 units.
Therefore correct option is C.

Let C ( t ) be the number of US cell phone subscribers in millions in t years since 1995. A linear model for the data is F ( t ) = 18.997 t + 17.711 .
Use the model to predict the year in which the number of subscribers will 324 million
ANSWER
In 16 years time.
EXPLANATION.
If the number of subscribers is 324 million, then it means
[tex]f(t)=324[/tex]
But we were given that,
[tex]f(t)=18.997t+16.711[/tex]
This implies that,
[tex]324=18.997t+16.711[/tex]
We now solve for t,
[tex]324-16.711=18.997t[/tex]
[tex]307.289=18.997t[/tex]
[tex]\frac{307.289}{18.997}=t[/tex]
[tex]16.17566=t[/tex]
That will be approximately in the 16th year.
In order to calculate the year where the number of US cell phone subscribers matches a certain number using the given linear model equation, you solve for the time variable. With the specified 324 million subscribers, the corresponding year would be approximately 2011.
Explanation:To use the provided linear model F(t) = 18.997t + 17.711 to predict the year where the number of subscribers will be 324 million, we need to solve the equation for t with C(t) set to 324:
324 = 18.997t + 17.711
To do so, subtract 17.711 from both sides to isolate the term with t:
324 - 17.711 = 18.997t
Then, divide both sides by 18.997 to solve for t:
(324 - 17.711) / 18.997 = t
After calculating, you will get approximately t = 16.123. Remember, t is the number of years after 1995, so you would add 16 (rounded from 16.123) to 1995. Thus, the model predicts that the number of US cell phone subscribers will reach 324 million in 2011.

x = 11 - [tex]\frac{4}{5}[/tex] = [tex]\frac{55}{5}[/tex] - [tex]\frac{4}{5}[/tex] = [tex]\frac{51}{5}[/tex]
Answer:
10.92 or 10 23/25
Step-by-step explanation:
What you do is you try to get X by itself so put the fraction 4/5 on the other side so that is turns out to be 11-4/5. Now you can turn 4/5 into a decimal which would be .8 and subtract that by 11which gives you 10.92 or if you want to keep it as a fraction .92 as a fraction is 23/25 so you get 10 23/25

Given: △DMN, DM=10 3 m∠M=75°, m∠N=45° Find: Perimeter of △DMN
Answer:
The perimeter of [tex]\triangle DMN[/tex] will be 62.1939...
Step-by-step explanation:
In [tex]\triangle DMN[/tex], the length of side [tex]DM = 10\sqrt{3}[/tex] and the measures of [tex]\angle M[/tex] and [tex]\angle N[/tex] are 75° and 45° respectively.
As the sum of all angles in a triangle is always 180°, so the measure of [tex]\angle D[/tex] will be: 180°- (75°+45°) = 180°- 120° = 60°
Now using Sine rule, we will get......
[tex]\frac{MN}{Sin(D)}=\frac{DN}{Sin(M)}=\frac{DM}{Sin(N)}\\ \\ \frac{MN}{Sin(60)}=\frac{DN}{Sin(75)}=\frac{10\sqrt{3}}{Sin(45)}\\ \\ MN= \frac{10\sqrt{3}}{Sin(45)}*Sin(60)=21.2132...\\ \\ DN=\frac{10\sqrt{3}}{Sin(45)}*Sin(75)=23.6602...[/tex]
So, the perimeter of [tex]\triangle DMN[/tex] will be: [tex]DM+MN+DN = 10\sqrt{3}+21.2132...+23.6602... =62.1939...[/tex]
Let f(x) = 5x2 – 4x and g(x) = 5x + 1.
Answer:
5x^2+x+1
Step-by-step explanation:
the expression for f(x) - g(x) is 5x² - 9x - 1.
To find f(x) - g(x), we simply subtract the expression for function g(x) from the expression for f(x):
f(x) - g(x) = (5x² - 4x) - (5x + 1)
Now, let's simplify the expression by combining like terms:
f(x) - g(x) = 5x² - 4x - 5x - 1
Next, combine the x terms:
f(x) - g(x) = 5x² - (4x + 5x) - 1
Now, combine the x terms inside the parentheses:
f(x) - g(x) = 5x² - 9x - 1
So, the expression for f(x) - g(x) is 5x² - 9x - 1.

In step 2 multiply what is inside the parenthesis by 7 (distributive property):
7 * x = 7x
7 * 3 = 21
In step 3 subtract -7x on both sides of the equation. (Property of subtraction of equality)
Then -7x + 4x = -3x
7x-7x + 21 = 21
In step 4, both sides of the equation are divided by -3. (owned by the equality division)
So:
-3x / -3 = x
-21 / -3 = 7

Paula bought a 5-pound bag of granola. She plans to use equal amounts of granola to make 10 bags of trail mix and add the remaining amount to her bird feeder. She created the given function to model the amount of granola, in ounces, that she can add to her bird feeder if she puts x ounces in each bag.
What is the range of the function?
A. all whole numbers between and including 0 and 8
B. all whole numbers between and including 0 and 80
C. all real numbers between and including 0 and 80
D. all real numbers between and including 0 and 8
Given function: P(x) = -10x + 80.
Where function represents the amount of granola, in ounces and x represents the number of ounces Paula puts in each bag.
Range of the function is the values of the function we would get.
That is the amount of granola in ounces for different x values.
For x=0 the number of ounces would be -10(0)+80 = 80.
And for x=8, it would be -10(8) + 80 = 0.
But even we could take decimal values too.
Like x=0.5 ounces, x=0.55 ounces etc.
And that 0.55 would give a decimal value.
Therefore, we can take any real number for x between 0 and 8.
But we need to find the range.
So, the range would be between 0 and 80 and it could be any real number.
Therefore, correct option is :
C. all real numbers between and including 0 and 80.

Which statement best describes the constant in this expression?
Answer:
A. It is the total cost for entertainment and cleaning.
Step-by-step explanation:
If we look at the information it says:
Facility rental is dependent upon number of hours we are renting the facility for.
Linen, food, and decoration also depends upon the number of attendees. Also, the table decorations depend upon the number of attendee.
The things that are independent of the number of attendees are entertainment and cleaning fee. These are fixed charges.
So, the total cost for entertainment and cleaning are the constants in the expression. This is the amount that will remain constant regardless of the number of attendees.
