WILL GIVE BRAINLIEST What is the solution to the equation 1 over 3 multiplied by n equals 6?
n = 3
n = 9
n = 18
n = 216
Step-by-step explanation:
Break down the word problem.
1 over 3 multiplied by n equals 6.
[tex] \frac{1}{3} \times n = 6[/tex]
Multiply each side by 3 to eliminate the fraction:
[tex]n = 18[/tex]
The sum of one third of a number and five is equal to six less than the number
Call the number : x
(1/3)x + 5 = x-6
=> (1/3)x + 5 - (x-6) = 0
=> (1/3)x + 5 - x + 6 = 0
Group (1/3)x with -x, 5 with 6
=> [(1/3)x - x] + (5+6) = 0
=> (-2/3)x + 11 = 0
=> (-2/3)x = -11
=> x = -11 : (-2/3) = 33/2.
Recheck : 1/3 x 33/2 + 5 = 33/6 + 5 = 63/6 = 21/2
33/2 - 21/2 = 12/2 = 6 (21/2 is 6 less than 33/2, satisfied.)
What constant term is necessary to complete the perfect square trinomial pictured in the algebra tiles? x2 8x.
The constant term which is necessary to complete the perfect square trinomial pictured in the algebra tiles is 16.
What is perfect square trinomials?A trinomial which is expressed as the square of the binomial equation is a perfect square trinomial.
Let the constant term which is necessary to complete the perfect square trinomial pictured in the algebra tiles is P. Thus the trinomial can be given as,
[tex]x^2+8x+P[/tex]
Now, the algebra tiles used to represent the algebraic expression in the table form. The shape of algebra tile is square and rectangle, in which the variables represented.
The two equal factor with the middle terms being 8x can be for a trinomial (x+4). Thus,
[tex]x^2+8x+P=(x+4)^2\\x^2+8x+P=x^2+8x+4^2\\x^2+8x+P=x^2+8x+16[/tex]
Comparing both sides, we get,
[tex]P=16[/tex]
Thus, the constant term which is necessary to complete the perfect square trinomial pictured in the algebra tiles is 16.

Find the measure of each interior angle of the regular polygon (The polygon has 12 sides)
Answer:
150°
Step-by-step explanation:
To find the sum of all the interior angles in a regular polygon, us this formula, where n is the number of sides: (n-2)*180
(12-2)=10
10*180=1800
Now we have the sum of all the angles. But we aren't done yet! We have to divide this value by the number of sides to find the measure of one angle.
So,
1800/12=
150
Hope this helps!
Answer:
150 degrees.
Step-by-step explanation:
So every polygon's interior angles will always add up to a multiple of 180 degrees depending on the amount of sides, if it's a regular polygon all interior angles will be the same.
(3 sides = 180 degrees, 4 sides = 360 degrees, 5 sides = 540 degrees etc.)
12 sides will always add up to 1800 degrees.
1800 / 12 = 150
Therefore, each interior angle is 150 degrees.

Answer:
well this is just 3 1/4 - 1 3/4
Step-by-step explanation:
1 2/4 (or just 1 1/2)
Ari will be a teenager in 1 3/4 years His little sister anna will be one in 3 1/4. The longer anna has to wait than ari is 1 2/4.
We have given that,

Marcy wants to know which type of book is most commonly checked out by visitors of her local public library. She surveys people in the children's reading room between 1:00 and 2:00 on Saturday afternoon. Which statements about Marcy's survey are true? Select all that apply.
It is true about Marcy's survey that she wants to study all visitors of the library and due to this, her sample is not representative.
What does Marcy want to study?Marcy's study focuses on determining the type of books that visitors prefer to borrow. Based on this, Marcy is studying the preferences of all the visitors to the library.
How was the sample Marcy selected?The sample selected is not representative because she is only considering those that go to the children's room on a specific day and time of the week rather than all the visitors.

write down Mrs chauke's balance on the 25march in words
Given:
f(g)=(-10*g^2+17*g-6) / (-15*g^2-2*g+24)
Factor both numerator and denominator:
f(g)=-(2g-1)(5g-6)/(-(3g+4)(5g-6))
if 5g-6≠0, we can cancel out the factor (5g-6).
We can also cancel the negative signs to simplify to
f(g)=(2g-1)/(3g+4) on condition that g≠6/5

(1,3) and (1, -10)
Step-by-step explanation:
The slope of 3 and -10.
If the slope is above 0, the line is increasing.
If the slope is at 0, it's a horizontal line or straight. Vertical If the run is 0.
If the slope is below 0, the line is decreasing.
3 is slanting upward, the slope is greater than 0 therefore the line is increasing.
-10 is slanting downward, the slope is less than 0 therefore the line is decreasing.

Additional comment
Some calculators use logarithms to compute powers. The logarithm of a negative number is undefined, so direct computation of this expression would give an error on such a device. You would have to recognize that the root and power are odd, so the result will be negative. Then you could calculate -(8^(5/3)) without error.
The rule of exponents used here is ...
(a^b)^c) = a^(bc)
