The last one because,
-9(2/3x+1)=
-6x - 9
because, negative 9 times positive 1 will be negative 9.

If point C is the circumcenter of
APQR and the circumcenter of
APQS, then R and S must be
the same point.
true
false
Answers
Point R and S cannot be the same point
The statement is false.
What is Circumcenter?The intersection of the perpendicular bisectors of a triangle's sides is known as the circumcenter of that particular triangle. In other terms, the circumcenter is the point at which the bisector of a triangle's sides coincides.
Given:
ΔPQR and ΔPQS both have same circumcenter named C.
As, both triangles have point P and Q same but S and R are different.
There many chances that they do not overlap or Coincide, they can be sharing same base but different vertex.
Hence, R and S cannot be the same point.

Gavin has a board that is ten feet long. Gavin is using the board to saw off pieces of wood needed for a building project. First Gavin saws off 2/10 of the board. Next Gavin saws off 5/10 of the board. Last Gavin saws off 1/10 of the board Gavin says he has 2/10 the board left to use for another building project is Gavin correct?
Answers
Answer:
Gavin is correct
Step-by-step explanation:
Since the problem is using a denominator of 10, I will convert 1 (1 representing the full length of the board before being sawed) to a fraction over 10
1 = 10/10
Subtract everything Gavin sawed off from the board
10/10 - 2/10 - 5/10 - 1/10
Only subtract the numerators; the denominators will stay the same
8/10 - 5/10 - 1/10
3/10 - 1/10
2/10
Gavin says he has 2/10 of the board left to use
Since we concluded we still have 2/10, he is correct

79 1/6% as a fraction
Answers
Answer:
475/6%
Step-by-step explanation:
I hope this helps.
The equivalent fraction of the percentage is A = 47401/600
What is a Fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given data ,
Let the fraction be represented as A
Now , the percentage value is given by P
And , the value of P = ( 79 1/6 ) %
We know that 1% is equivalent to 1/100, so we can write:
79 1/6% = 79 + 1/6% = 79 + 1/6 x 1% = 79 + 1/600
Now, we can convert the mixed number to an improper fraction by multiplying the whole number by the denominator and adding the numerator, then placing this over the denominator:
79 + 1/600 = (79 x 600)/600 + 1/600 = 47400/600 + 1/600
Combining these fractions, we get:
79 1/6% = 47401/600
Hence , 79 1/6% as a fraction is 47401/600.

How much 9% saline solution should be mixed with 80 Cc of a 17% saline solution to produce a 13% saline solution?
Answers
Answer:
80 cc.
Step-by-step explanation:
We work in amounts of salt in the solutions:
0.09x + 0.17*80= 0.13(x+ 80) where x is the required volume of 9% solution.
0.09x + 13.6 = 0.13x + 10.4
13.6 - 10.4 = 0.13x - 0.09x
3.2 = 0.04x
x = 3.2 / 0.04
x = 80

2 days with no professional sports game.
3 forms of ratio --> a to b, a : b, a / b
1) Remember there are 365 days in a year.
Days without games to Days in a year --> 2 to 365
Days without games : Days in a year --> 2 : 365
Days without games / Days in a year --> 2 / 365
2) Now there is a plot twist. It ask days with games. To find that we need to subtract 365 - 2 = 363 days with games.
Days with games to Days in a year --> 363 to 365
Days with games : Days in a year --> 363 : 365
Days with games / Days in a year --> 363 / 365
3) Days with games to Days without games --> 363 to 2
Days with games : Days without games --> 363 : 2
Days with games / Days without games --> 363 / 2
