The triangular base has a base of 6 meters and height of 13 meters. The height of the prism is 5 meters. A triangular prism. The triangular base has a base of 11 meters and height of 8 meters. The height of the prism is 8 meters. A triangular prism. The triangular base has a base of 10 meters and height of 9 meters. The height of the prism is 8 meters.
Answer: The correct answer is option 4;
A triangular prism. The triangular base has a base of 10 metres and a height of 9 metres. The height of the prism is 8 metres.
Step-by-step explanation: A simple check for the result of each set of dimensions would give the correct answer.
The volume of a right triangular prism is derived as follows;
Volume = 1/2 * b * h * l
Where, b is the base of the triangle, h is the vertical height of the triangle and l is the length of the prism.
Note that the area of the right triangle is denoted by 1/2 * b * h, and multiplying this result by the length of the prism gives the entire depth or volume of the triangular prism. Let us examine the dimensions one after the other;
(1) A triangular prism. The triangular base has a base of 7 metres and height of 9 metres. The height of the prism is 6 metres.
Volume = 1/2 * 7 * 9 * 6
Volume = 189 cubic metres
(2) A triangular prism. The triangular base has a base of 6 metres and height of 13 metres. The height of the prism is 5 metres.
Volume = 1/2 * 6 * 13 * 5
Volume = 165 cubic metres
(3) A triangular prism. The triangular base has a base of 11 metres and a height of 8 metres. The height of the prism is 8 metres.
Volume = 1/2 * 11 * 8 * 8
Volume = 352 cubic metres
(4) A triangular prism. The triangular base has a base of 10 metres and a height of 9 metres. The height of the prism is 8 metres.
Volume = 1/2 * 10 * 9 * 8
Volume = 360 cubic metres

Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ KLM is an external angle of the triangle, thus
∠ KLM = ∠ JKL + ∠ KJL , substitute values
5x - 7 = x + 20 + 2x + 3
5x - 7 = 3x + 23 ( subtract 3x from both sides )
2x - 7 = 23 ( add 7 to both sides )
2x = 30 ( divide both sides by 2 )
x = 15
89 x (100-2) = 98 x (100-x) What should replace 'x' to make the equation true?
Answer:
x=11
Step-by-step explanation:
the 100-2=98 so you would need the 98 times 89 on both sides or something that is equal
[tex]\bigstar\bf\:89\times (100-2)=98\times (100-x)[/tex]
[tex]:\implies\tt\:89\times 98=98\times (100-x)[/tex]
[tex]:\implies\tt\:100-x=\dfrac{89\times 98}{98}[/tex]
[tex]:\implies\tt\:100-x=89[/tex]
[tex]:\implies\tt\:x=100-89[/tex]

Step-by-step explanation:
find a pattern: +3, -2
the missing numbers are 8 and 12
Answer:
The numbers missing are 8 and 7.
Step-by-step explanation:
First you need to find a pattern in the numbers. You will notice that the pattern is add 3, subtract two. This is because, to get from 4 to 7, you add three, and to get from 7 to 5, you subtract 2.
When you apply that pattern, you find the missing numbers.
5(+3)=8, then 8(-2)=6, then 6(+3)=9, then 9-2=7, then 7(+3)=10

Reflecting the graph of y = sin x across the yaxis is the same as reflecting it
across the x-axis.
TRUE OR FALSE
Answer:
True
Step-by-step explanation:
Answer:
TRUE
Step-by-step explanation:
This is due to the symmetry of the sin function, which states that:
[tex]sin(-x)=-sin(x)[/tex]
Plotting both of these functions is a reflection of [tex]y=sin(x)[/tex] in both axis.
HELLO THERE. PLS HELP ME WITH MY GEOMETRY
Answer:
(0,-2) = No
(-5,0) = Yes
(8,0) = Yes
(-9,-6) = No
Step-by-step explanation:
It says "solution to y = 0" so then look at the y-axis which is the second number in parenthesis.
Ex: (0, -2), y is -2 and x is 0.
Just make sure the second number is equal to 0, if not, then that is not the solution.
A certain club has $50$ people, and $4$ members are running for president. Each club member votes for one of the $4$ candidates. How many different possible vote totals are there?
Answer:
The number of different possible vote totals is 184.
Step-by-step explanation:
It is provided that there are N = 50 people in a club.
The position of President is open. And there are x = 4 members running for he post of President.
So, there are n = N - x = 50 - 4 = 46 people voting for these 4 members.
Each member of the club has x = 4 possible choices.
So, the number of different possible vote totals are:
Number of different possible votes = n × x
= 46 × 4
= 184
Thus, the number of different possible vote totals is 184.

Which of the following is a true proportion of the figure based on the triangle proportionality theorem? answers: A) ab= dc B) ac=ad C) ab=ac D) bd=ca
Answer:
A) a/b = d/c
Step-by-step explanation:
The Triangle Proportionality Theorem states that if a line is parallel to one side of a triangle and it intersects the other two sides, then it divides those sides proportionally.
In this case, line TU is parallel to side QR. So, the ratios a:b and d:c are equal. In other words, a/b = d/c

HAVE A GOOD DAY!
Compute i^1+i^2+i^3+...+ i^97 + i^98+i^99.
If [tex]i=\sqrt{-1}[/tex], then [tex]i^2=-1[/tex], [tex]i^3=-i[/tex], and [tex]i^4=1[/tex].
We can break up the given sum into 25 groups (after adding and subtracting [tex]i^{100}[/tex]):
[tex](i+i^2+i^3+i^4)+(i^5+i^6+i^7+i^8)+\cdots+(i^{97}+i^{98}+i^{99}+i^{100})-i^{100}[/tex]
We have
[tex]i+i^2+i^3+i^4=i-1-i+1=0[/tex]
and in each group, we can pull this out as a factor. For example,
[tex]i^{97}+i^{98}+i^{99}+i^{100}=i^{96}(i+i^2+i^3+i^4)=0[/tex]
So the entire sum reduces to the remaining term,
[tex]-i^{100}=-i^{25\cdot4}=-(i^4)^{25}=-1^{25}=\boxed{-1}[/tex]

Here is a sketch of a curve.
YA
The equation of the curve is y = x2 + ax + b
where a and b are integers.
The points (0, -7) and (7, 0) lie on the curve.
Find the coordinates of the turning point of the curve.
Answer:
The turning point of the graph is at (3,-16)
Step-by-step explanation:
The general equation of curve is given as:
y = x² + ax + b
The two point for which the equation satisfies is (0,-7) and (7,0).
Substitute (0,-7) in the general equation:
y = x² + ax + b
-7 = 0² + a(0) + b
b = -7
Substitute (7,0) in the general equation:
y = x² + ax + b
0 = 7² + 7a + b
Where b = -7
0 = 49 + 7a - 7
0 = 42 + 7a
a = -6
The equation of the curve is:
a = -6 and b = -7
y = x² + ax + b
y = x² - 6x - 7
Graph of the equation is attached below.
We can see that the the turning point of the graph is at (3,-16)

John goes running every morning. He can run 3 miles in 1 hour. How many miles would he be able to run in 1 and ½ hours? A. 4.5 miles B. 2 miles C. 6 miles D. 10 miles
Answer:
2
Step-by-step explanation:
well less than 3
Answer:
A
Step-by-step explanation:
The easiest way to do this problem is to find out how far he can go in 1/2 hour.
If he goes 3 miles in 1 hour
he will go 3/2 miles in 1/2 hour
=============
Now just add this onto the distance travelled in 1 hour.
3 + 3/2 = 3 + 1.5 = 4.5
The answer is A
The answer can be obtained another (perhaps better ) way.
Set up a proportion
1 hour gives 3 miles
1.5 hours gives x
1/1.5 = 3/x Cross multiply
1*x = 1.5 * 3 Combine
x = 4.5 miles
A table has an area of 12 ft^2 and a perimeter of 16 ft. What are the dimensions of the table?
Answer:
2 and 6
Step-by-step explanation:
Well if the are is 12ft^2 and the perimeter is 16 ft then the length is 6 ft and the width is 2 ft.
So 6+6+2+2=16
6*2 is 12
Answer:
Step-by-step explanation:
hello,
we can assume that the table is a rectangle
so let's note x , y its length and width, we can write
(1 ) 2(x+y)=16
(2) xy=12
x and y are different from 0 and from (2) we can write
y =12/x we replace it in (1)
x+12/x=16/2=8
[tex]<=> x^2+12=8x\\<=> x^2-8x+12 = 0\\<=> x^2 -2x-6x+12=0\\<=> x(x-2)-6(x-2)=0\\<=> (x-6)(x-2)=0\\<=> x = 6 \ \ or \ \ x=2[/tex]
for x = 6 y = 2
for x = 2 y = 6
so the dimensions of the table is 2ft x 6ft
hope this helps

Which sets are best represented by the Venn diagram G = {odd numbers)
H = {even numbers)
1 = {prime numbers
B. G = {a,b,c}
H = {d, e, f}
1 = {a, d, g}
C. G= {1, 2, 3
H = {2, 4, 9}
1 = {4, 5, 6)
D. G={a, -13,7}
H={-13, -15, s}
1 = {s, a, 23}
Answer:
option C.
G = {1, 2, 3}
H = {2, 4, 9}
1 = {4, 5, 6}
Step-by-step explanation:
From the diagram given above, we obtained the following information:
1. G Intercession H (G n H) has members i.e (G n H) is not epmty
G n H ≠ empty.
2. H Intercession I (H n I) has members i.e (H n I) is not empty
H n I ≠ empty.
3. G Intercession I (G n I) is empty i.e
G n I = empty.
Please note: Intercession of sets talks about elements or members common to the sets.
With the above information, we can suggest the answer to the question as follow:
For option A:
G = {odd numbers} = {1, 3, 5, 7,.. }
H = {even numbers} = {2, 4, 6, 8,.. }
I = {prime numbers} = {2, 3, 5, 7,...}
Therefore:
G n H = {} = empty
H n I = {2}
G n I = {3, 5, 7,..}
For option B:
G = {a,b,c}
H = {d, e, f}
I = {a, d, g}
Therefore:
G n H = {} = empty
H n I = {d}
G n I = {a}
For option C:
G = {1, 2, 3}
H = {2, 4, 9}
I = {4, 5, 6}
Therefore:
G n H = {2}
H n I = {4}
G n I = {} = empty
For option D:
G = {a, -13, 7}
H = {-13, -15, s}
I = {s, a, 23}
Therefore:
G n H = {-13}
H n I = {s}
G n I = {a}
From the above illustrations, only option C is correct.
