In order to ensure that the roof consists of right angles, an architect measures the diagonal to create a triangle. If the dimensions of the
triangle are 9.5 feet, 16 feet, and 18.5 feet, is the triangle a right triangle?
Answer:I have a question
Step-by-step explanation:
About that question is it a right triangle or no
The triangles with side lengths 9.5 feet , 16 feet and 18.5 feet is an acute triangle
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the height of the triangle is AB = 16 feet
The base of the triangle is BC = 9.5 feet
The hypotenuse of the triangle is AC = 18.5 feet
And , for a triangle , if a² + b² > c² , it is an acute triangle
Substituting the values in the equation , we get
( 9.5 )² + ( 16 )² > ( 18.5 )²
90.25 + 256 > 342.25
346.25 > 342.25
Hence , the triangle is an acute triangle

Bob's can make 10 hamburgers in 3 minutes. How many
minutes does it take Bob's to make one burger?
Answer:
3 minutes and 34 seconds
Answer:
Bob's can make one burger in 0.3 minutes, or 18 seconds.
Step-by-step explanation:
Bob's can make 10 hamburgers in 3 minutes. To determine how long it takes Bob's to make a single hamburger, we divide the 3 minutes by the 10 hamburgers.
3/10 = 0.3 minutes
It takes him 0.3 minutes to make one burger.
We could go further and convert this time to seconds. To do this, we multiply 0.3 minutes by 60 seconds.
0.3 ⋅ 60 = 18 seconds
Bob's can make one hamburger in 18 seconds.

Your school is organizing a carnival. You are building a ramp for a game. The surface of the ramp will be 7 feet long with a total rise of 2 feet. Find the angle of elevation of the ramp.
Answer:
[tex]\theta=16.6^{\circ}[/tex]
Step-by-step explanation:
Given that,
The surface of the ramp will be 7 feet long with a total rise of 2 feet.
We need to find the angle of elevation of the ramp. We can use trigonometry to find it such that,
[tex]\sin\theta=\dfrac{P}{H}[/tex]
P is perpendicular
H is hypotenuse
Here, P = 2 feet, H = 7 feet
So,
[tex]\sin\theta=\dfrac{2}{7}\\\\\theta=16.6^{\circ}[/tex]
So, the angle of elevation of the ramp is equal to [tex]16.6^{\circ}[/tex].

Derrick needs to figure out how he’s doing on his test scores so far this year. You can help by calculating the mean and the median to get an overall picture of his scores. Below are all of his scores:
25, 40, 68, 85, 95, 98, 70, 78, 85, 100
Answer:
Mean = 74.4
Median = 81.5
Step-by-step explanation:
25, 40, 68, 85, 95, 98, 70, 78, 85, 100
Mean = Sum of values / Number of values
Number of values = 10
= 25 + 40 + 68 + 70 + 78 + 85 + 85 + 95 + 98 + 100/10
= 744/10
= 74.4
Median
Rearranging the given data
= 25, 40 ,68 ,70 ,78 ,85 ,85 , 95 ,98 ,100
Formula for median = 1/2(n + 1)th value
n = 10
Hence
1/2(10 + 1)th value
1/2(11)th value
= 5.5 th value
This fall between the 5th and 6th value
5th value = 78
6th value = 85
Hence: 78 + 85/2
= 163 / 2
= 81.5

Answer:
C
Step-by-step explanation:
The reason we shall be choosing the graph c is as a result of the plot type
Now, looking at the inequalities, we can see that the second inequality does not have an equal to assigned
Whenever we want to plot this kind of inequality, we are going to use the dotted line in place of the thick line used in cases where we have the equal to assigned to the inequality
So, what this looks like is that only the option C has the correct representation of the dotted line and thus represents our answer

The volume of a cube is 64 cubic meters. What is the surface area of the cube, in square meters?
Answer:
96 square meters
Step-by-step explanation:
Figuring out the side length of a cube from its volume is fairly simple. Using the cubic root we are able to deduce that the side length is 4 meters.
We then find the area of one face which is 4 * 4 = 16 square meters.
We must then multiply this by the amount of sides on our cube which is 6.
16 * 6 = 96 square meters.

let f(x) = 1/x-3 and g(x) = the square root of x+5. What is the domain of (f o g) (x)
Answer:
the second one
Step-by-step explanation:
Option B is correct. the required domain of the function will be expressed as [-5, 3) U (3, ∞)
The domain of a function is the input function for which a function exists.
Given the functions
f(x) = 1/x-3
g(x) = √x+5
Get the composite function (f o g) (x)
(f o g) (x) = f(g(x))
f(g(x)) = f( √x+5)
[tex]f(g(x)) =\frac{1}{\sqrt{x+5}-3 }[/tex]
According to the function gotten, we can see that the domain of the fucntion will exist for all values of x except at x = 4. The function tends to infinity at x = 4. Hence the required domain of the function will be expressed as [-5, 3) U (3, ∞)

40/50 = x/100
solve for x
x is equal to 20%
but out of the answer choices it's 19%.
Answer: 19%
Step-by-step explanation:
50, percentage decreased by 60% (percent) of its value = 20
50, percentage decreased by 80% (percent) of its value = 10

Answer:
216 cm^2
Step-by-step explanation:
Alright, first lets knock out the rectangle. This would be found by doing L * H. For the length it would be 14. For the height, it would be 12.
14 * 12 = 168
Next with the triangle, it has a length, or "base" of 8 and the same height of 12. For a triangle, do (B * H) / 2 as the formula.
(8 * 12) / 2
96 / 2
48
Now, combine these two values to get the total:
168 + 48 = 216 cm^2
All done!
