Answer:
52
Step-by-step explanation:
The triangle is 180o
if B and C are 56 and 72
that means 56 + 72 = 128
so B + C = 128
and finally
180 - 128 = 52
A = 52
Answer: A= 52
Step-by-step explanation:
Based on the formula for triangles, A = bh/2, I did that and got 24.5 but since there are 2 of the triangles I did 24.5 x 2 = 49. I know that the line in the triangle means they are congruent. But are they congruent to show that the base and height is 7 x 7 for the one that the line is crossing of does it show that itś 7x7 for both triangles?
I found the area of the square and subtracted that from the area of the triangles to get 147.
My area of the triangles is 49ft^2
My area of the pebbles is 147ft^2.
Is this correct?
Answer:
Right
Step-by-step explanation:
What is the area of the following circle?
radius =1
Answer:
π
Step-by-step explanation:
The formula to find the area of a circle is πr^2. If we know that the radius is 1, we just have to substitute that for r:
π(1)^2
= π1
= π
What are coordinates of point X
Answer:
(3.5,3.5) are the coordinates of X
Answer:
(-3.5, -3)
Step-by-step explanation:
To get to point X, you have to travel -3.5 on the X-axis and -3 on the Y-axis. That means the answer is (-3.5, -3).

Which expression is equivalent to log5[x/4]^2?
Answer:
2log(base 5)x - 2log(base 5)4
Step-by-step explanation:
The expression which is equivalent to [tex]log_5[/tex] [tex][x/4]^2[/tex] is c) 2[tex]log_5[/tex] x-2[tex]log_5[/tex] 4.
The answer is c. 2[tex]log_5[/tex] x - 2[tex]log_5[/tex] 4.
We can use the power rule of logarithms to simplify the expression [tex]log_5[/tex] [tex][x/4]^2[/tex]. The power rule of logarithms states that [tex]log_a[/tex] [tex]b^c[/tex] = c[tex]log_a[/tex] b.
In this case, we have [tex]log_5[/tex] [tex][x/4]^2[/tex] =[tex]log_5[/tex] [tex](x/4)^2[/tex] = 2[tex]log_5[/tex] (x/4).
We can then use the quotient rule of logarithms to simplify the expression further. The quotient rule of logarithms states that [tex]log_a[/tex] (b/c) = [tex]log_a[/tex] b - [tex]log_a[/tex] c.
In this case, we have 2[tex]log_5[/tex] (x/4) = 2[tex]log_5[/tex] x - 2[tex]log_5[/tex] 4.
Therefore, the equivalent expression to [tex]log_5[/tex] [tex][x/4]^2[/tex] is 2[tex]log_5[/tex] x-2[tex]log_5[/tex] 4.
The other expressions are not equivalent to [tex]log_5[/tex] [tex][x/4]^2[/tex]. Option a is not equivalent because it has an extra [tex]log_5[/tex] 4 term. Option b is not equivalent because it has a [tex]log_5[/tex] 16 term. Option d is not equivalent because it does not have the -2[tex]log_5[/tex] 4 term.

Here , we are provided with a table which shows 5 consecutive terms of an arithmetic sequence . But before solving further , let's recall that ;
The n'th term of a Arithmetic Sequence let's say it be [tex]{\sf T_n}[/tex] is given by ;
[tex]{\boxed{\bf T_{n}=T_{1}+(n-1)d}}[/tex]Where , d is the common difference
Now , here we are given with ;
[tex]{\quad \qquad \sf \blacktriangleright \blacktriangleright \blacktriangleright T_{1}=8 \: and \: T_{5}=-4}[/tex]
We have to find the 2nd , 3rd and 4th term respectively ,
Now , by using the above formula , 5th term can be written as ;
[tex]{: \implies \quad \sf T_{1}+(5-1)d=T_{5}}[/tex]
Putting the values and transposing 1st term to RHS , we have ;
[tex]{: \implies \quad \sf 4d = -4-8}[/tex]
[tex]{: \implies \quad \sf d=-\dfrac{12}{4}}[/tex]
[tex]{: \implies \quad \sf d=-3}[/tex]
Now , as we got the common difference , so we can find out the missing terms now ;
[tex]{: \implies \quad \sf T_{2}= T_{1}+(2-1)d}[/tex]
[tex]{: \implies \quad \sf T_{2}= 8 +d}[/tex]
[tex]{: \implies \quad \sf T_{2}= 8-3}[/tex]
[tex]{: \implies \quad \bf \therefore \: T_{2}= 5}[/tex]
Now
[tex]{: \implies \quad \sf T_{3}= T_{1}+(3-1)d}[/tex]
[tex]{: \implies \quad \sf T_{3}= 8 +2d}[/tex]
[tex]{: \implies \quad \sf T_{3}= 8-6}[/tex]
[tex]{: \implies \quad \bf \therefore \: T_{3}= 2}[/tex]
Also ,
[tex]{: \implies \quad \sf T_{4}= T_{1}+(4-1)d}[/tex]
[tex]{: \implies \quad \sf T_{4}= 8 +3d}[/tex]
[tex]{: \implies \quad \sf T_{4}= 8-9}[/tex]
[tex]{: \implies \quad \bf \therefore \: T_{4}= -1}[/tex]
Now , The given table can be written as ;
[tex]{\begin{array}{|c|c|c|c|c|c|}\cline{1-6} \bf n & \sf 1 & 2 & 3 & 4 & 5 \\ \cline{1-6} \bf T_{n} & \sf 8 & 5 & 2 & -1 & -4 \end{array}}[/tex]

Given the data from the question, the 2nd, 3rd and 4th term of the sequence are:
The 2nd term is 5The 3rd term is 2The 4th term is –1What is an arithmetic sequence?This is a type of sequence which have common difference between each term. It is represent mathematically as:
Tₙ = a + (n – 1)d
Where
Tₙ is the nth term
a is the first term
n is the number of terms
d is the common difference
How to determine the common difference First term (a) = 8Number of terms (n) = 55th term (T₅) = –4Common difference = ?Tₙ = a + (n – 1)d
T₅ = 8 + (5 – 1)d
–4 = 8 + (4)d
Collect like terms
–4 – 8 = 4d
–12 = 4d
Divide both side by 3
d = –12 / 4
d = –3
How to determine the 2nd termFirst term (a) = 8Common difference (d) = –3Number of terms (n) = 22nd term (T₂) =?Tₙ = a + (n – 1)d
T₂ = 8 + (2 – 1)(–3)
T₂ = 8 + (1)(–3)
T₂ = 8 – 3
T₂ = 5
How to determine the 3rd termFirst term (a) = 8Common difference (d) = –3Number of terms (n) = 33rd term (T₃) =?Tₙ = a + (n – 1)d
T₃ = 8 + (3 – 1)(–3)

T₃ = 8 – 6
T₃ = 2
How to determine the 4th termFirst term (a) = 8Common difference (d) = –3Number of terms (n) = 44th term (T₄) =?Tₙ = a + (n – 1)d
T₄ = 8 + (4 – 1)(–3)

Answer:
2708
Step-by-step explanation:
If there are 12 times as many students as professors all you have to do is divide the amount of students my 12 (32,500/12)
32,500/12 = 2708.3333 (3 keeps repeating)
