The figure shown is created by joining three rectangles. Enter the area of the figure, in square centimeters. Round to the nearest hundredth.
Answer:
235
Step-by-step explanation:
first, separate the floor into 3 different rectangles to calculate the area and then add them together.
area of rec=L*B
rec 1: 9*12.5=112.5
rec 2: (13.5-5.5)*(19.5-9-7)=28
rec 3:7*13.5=94.5
Then:
112.5+28+94.5=235

Answer:
W(x) = 27/256(x)(32-x)
Step-by-step explanation:
There are several ways you can do this. The method we've used here is to write a function that has zeros at x=0 and x=32, opens downward, and has a maximum at x=16 of 27.
The zeros give rise to the factored form ...
w = x(x -32)
To make it open downward, we need to reflect this across the x-axis. We can add a leading minus sign, or we can swap the terms in the binomial that has a minus sign:
w = -x(x -32) = x(32 -x)
This will have a value of 16(32 -16) = 256 at its peak. We want the peak to be 27, so we can vertically scale this function by a factor of 27/256. The grap attached shows this gives the desired result.
W(x) = (27/256)(x)(32-x)

Answer:
72
Step-by-step explanation:
Volume of a triangular prism = L x B x H x 1 / 2
So in this case itd be
V = 2 x 9 x 8 x 1/2
V = 72 x 1/2
V = 36
Now it wants BOTH prisms and their congruent so
36 x 2 = 72
Answer:
The answer is C.
Explanation:
C is the answer because volume you multiply length times width times height. 9 times 2 time 8 = 144. When you use volume, it is always going to be to the 3rd power or cubed. Any way you say it.

What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the 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,
From the graph,
The y coordinate values are the range of the function.

Step-by-step explanation:
Newton’s law of cooling states that the temperature of an object changes at a rate proportional to the difference between its temperature and that of its surroundings. Suppose that the temperature of a cup of coffee obeys Newton’s law of cooling. If the coffee has a temperature of 200◦F when freshly poured, and 1 min later has cooled to 190◦F in a room at 70◦F, determine when the coffee reaches a temperature of 150◦F.
Answer:
6 mins
Step-by-step explanation:
Given that;
T(t) = Ce^-kt + T(s)
Since T(t) = 200◦F, and T(s) = 70◦F where t = 0
200= Ce^-k(0) + 70
C= 200 - 70
C = 130
Then when T(t) = 190◦F and t= 1s ;
190 = 130e^-(k *1) + 70
190 - 70 = 130e-^(k *1)
120/130 = e^k
0.923 = e^-k
-k = ln(0.923)
k = 0.08
To determine the time taken to reach a temperature of 150◦F
150 = 130e^-(0.08t) + 70
150 - 70/130 = e^-(0.08t)
0.6154 = e^-(0.08t)
-(0.08t) = ln 0.6154
0.08t = 0.4855
t = 0.4855/0.08
t = 6 mins

V

Answer: 70, 130
Step-by-step explanation:
In the given normal distribution with a mean of 100 and standard distribution of 15, 95% of values will fall between 70 and 130 using the Empirical rule of 95%.
Step-by-step explanation:
A normal distribution with a mean of 100 and a standard distribution of 15 is given.
We will find where 95% of data fall in the given normal distribution.
What is the Empirical rule of 95%?It states that in a normal distribution approximately 95% of observations fall within two standard deviations from the mean on both sides of the normal curve.
The mean in a normal distribution is the center of the normal curve.
The standard deviation in a normal distribution is the distance from the mean to the required point on either side.
We have,
Mean = 100
Standard deviation = 15
Applying the 95% rule we get,
On the right side of the normal curve
Mean + 2 x standard deviation = 100 + 2x 15 = 100 + 30 = 130.
On the left side of the normal curve,
Mean - 2 x standard deviation = 100 - 2x15 = 100 - 30 = 70.
Thus, we see that by using the Empirical rule of 95%, 95% values will fall between 70 and 130.

Find the exact value of tan A in simplest radical form.
The scatter plot shows the results of a survey conducted by a T-shirt manufacturing company. A line of best fit was found for the data with the equation y -5x + 80, where y is the number of T-shirts sold and x is the price of a T-shirt. 85 70 60 55 50 Number of T-shirts 40 35 30 25 20 15 10 5 0 1 2 3 4 5 6 7 8 9 10 11 Price of a T-shirt (dollars)
Answer:
A
Step-by-step explanation:
As the price goes up per dollar there is a definite decrease in sales. Specifically, about 5 shirts don't get sold per increase of one dollar.
The correct option is A. for every one dollar price increase of T- shirt, 5 fewer T-shirts were sold.
What is a scatter plot?A scatter plot is a type of data visualization that shows the relationship between different variables. This data is shown by placing various data points between an x- and y-axis. Essentially, each of these data points looks “scattered” around the graph,
Given equation of line for that fits best for scattered data is y -5x + 80
From the graph it is clear that as the slope of the given equation is decreasing one
y -5x + 80 =0
y ∝ -mx
(no. of T-shirts sold) ∝ (-5) × (price of a T-shirt)
So, as the price of the T-shirt increases the less T-shirt were sold.

What is the value of x in the figure?
(4x + 2)
150°
Answer:
x=37
Step-by-step explanation:
By Vertical Angles Theorem (VAT), (4x+2) is equal to 150º, so then you just subtract 2 from both sides of the equation 4x+2 = 150, to make it 4x = 148, and then divide both sides by 4 to isolate x, and then you get x=37.
on a piece of paper graph y=(x+2)(x-3) then determine which answer choice best matches the graph you drew. Provide an explanation comments for links will be reported.
Answer:
option C
Step-by-step explanation:
Given :-
y = (x + 2)( x -3)And we need to tell which graph best matches the graph we drew. Firstly let's convert it into a quadratic equation by opening and simplifying the brackets.
[tex]:\implies[/tex] y = ( x + 2) ( x - 3)
[tex]:\implies[/tex] y = x ( x - 3)+2( x - 3)
[tex]:\implies[/tex] y = x² - 3x + 2x -6
[tex]:\implies[/tex] y = x² - x - 6
Now plot its graph. For that refer to attachment.
Things we can interpret :-
The constant in the equation is -6. So the graph will cut y axis 6 units below the X axis . At (-6,0) From the given options , option C matches the above point .Therefore the correct option is (C) .
