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

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

y=3/2x-9
I need to find the x-intercept and the y-intercept with work plsss

Answers

Hi there!

x-int: (6, 0)

y-int: (0, -9)

y = 3/2x - 9

Begin by finding the x-intercept. The x-intercept is located where y = 0, therefore:

0 = 3/2x - 9

Isolate for x by adding 9 to both sides:

9 = 3/2x

Divide both sides by 3/2x:

9 * 2/3 = x

x = 6. Thus, the x-intercept is at (6, 0).

Find the y-intercept by finding the y-value at which x = 0:

y = 3/2(0) - 9

y = -9. The y-intercept is at (0, -9).

What is equivalent to 0 = 2x2 - 16x – 18 when completing the
square?

Answers

Answer:

x = 1

x = -9

Step-by-step explanation:

(2x2 + 16x) - 18 = 0

2x2 + 16x - 18 = 2 • (x2 + 8x - 9)

x2 + 8x - 9

-9 + 1 = -8

-3 + 3 = 0

-1 + 9 = 8

2 • (x + 9) • (x - 1) = 0

2 = 0

x+9 = 0

x = -9

x-1 = 0

x = 1

x2 + 8x - 9 = 0

x2+8x = 9

(x+4) • (x+4) =

(x+4)2

x2+8x+16 = 25 and

x2+8x+16 = (x+4)2

(x+4)2 = 25

x = -4 + √ 25

x2 + 8x - 9 = 0

has two solutions:

x = -4 + √ 25

x = -4 - √ 25

- B ± √ B2-4AC

x = ————————

A = 1

B = 8

C = -9

B2 - 4AC =

64 - (-36) =

100

-8 ± √ 100

x = —————

x = ( -8 ± 10) / 2

x =(-8+√100)/2=-4+5= 1.000

or:

x =(-8-√100)/2=-4-5= -9.000

Answer: x = 1

x = -9

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

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.
