can someone help me for question 3?
Answers
So we know that according to the law of multiplying exponents that when multiplying them, you are just adding them together
With that in mind, x/6+x/8=10
From here, we can just solve for x!
Multiply both sides by 24
4x+3x=240
Add the x’s
7x=240
Anddddd divide both sides by 7
x=240/7
Remember, you can always double check your answer by plugging in your answer into your original equation! :)

50 points! Tell whether the orthocenter is inside, on, or outside the triangle. Then find the coordinates of the orthocenter.
Q(-1, 5), R(4, 3), S(-1, -2)
Answers
Answer:
(1,3) is inside the triangleStep-by-step explanation:
Orthocenter is the intersection of altitudes.
We'll calculate the slopes of the two sides and their altitudes ad find the intersection.
Side QRm = (3 - 5)/(4 - (-1)) = -2/5Perpendicular slope:
-1/m = 5/2Perpendicular line passes through S(-1, -2):
y - (-2) = 5/2(x - (-1)) ⇒ y = 5/2x + 1/2Side RSm = (-2 - 3)/(-1 -4) = -5/-5 = 1Perpendicular slope:
-1/m = -1/1 = -1Perpendicular line passes through Q(-1, 5):
y - 5 = -(x - (-1)) ⇒ y = -x + 4The intersection of the two lines is the orthocenter.
Solve the system of equations to get the coordinates of the orthocenter:
5/2x + 1/2 = x + 45x + 1 = -2x + 87x = 7x = 1Find y-coordinate:
y = -1 + 4 = 3The orthocenter is (1, 3)
If we plot the points, we'll see it is inside the triangle

What is the common difference (d) of the A.P. 7, 1, – 5, – 11, ... ?
Answers
Answer:
d = -6
Step-by-step explanation:
t1 = 7, t2 = 1, t3 = -5, t4 = -11
t2 - t1 = 1 - 7 = -6
t3 - t2 = -5 - 1 = -6
t4 - t3 = - 11 - (- 5) = -11 + 5 = -6
Therefore, the common difference is constant( I. e -6). Therefore the common difference is -6.

Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
= [tex]\frac{15+16+21+23+25+25+25+39}{8}[/tex]
= [tex]\frac{189}{8}[/tex]
= 23.6 ( to 1 dec. place )
The median is the middle value of the data set. If there is no exact middle then it is the average of the values either side of the middle.
15 16 21 23 25 25 25 39
↑ middle
median = [tex]\frac{23+25}{2}[/tex] = [tex]\frac{48}{2}[/tex] = 24
The mode is the value that occurs most often, that is 25
Thus
mean = 23.6 , median = 24 , mode = 25

Answer:
A) 6 square meters
Step-by-step explanation:
To find the area of a triangle you must multiple the base and the height, but in this question the base isn't given. Using the Pythagorean theorem to find the base you get 4 as the base. Now you multiply 3 and 4 to get 12 (square area), then divide it by two and get 6 (triangle area)
Steps:
b^2 = 5^2 - 3^2
b^2 = 16
[tex]\sqrt{b} = 4[/tex]
3*4 = 12
12/2 = 6 square meters

find the 50ty term if the nth term is 5n-3
Answers
Answer:
247
Step-by-step explanation:
From the question given above, the following data were obtained:
nth term (Tₙ) = 5n – 3
Number of term (n) = 50
50th term (T₅₀) =?
The 50th term can be obtained as follow:
Tₙ = 5n – 3
T₅₀ = 5(50) – 3
T₅₀ = 250 – 3
T₅₀ = 247
Therefore, the 50th term is 247.

Answers
Answer:
1/3
Step-by-step explanation:
First find the LCD or least common denominator. The least common denominator is the number that both of the denominators are divisible by.
In this case, 2 and 3 are both divisible by 6.
Convert both fractions into a fraction with a denominator of 6.
1/2 = 3/6 (multiply numerator and denominator by 3)
2/3 = 4/6 (multiply numerator and denominator by 2)
Now you can multiply as they have the same denominator.
3/6 × 4/6 = 12/36
Simplify.
12/36 = 1/3 (numerator and denominator are divisible by 12)
Hope that helps.
