In a bag, Bag C, the ratio of red counters to yellow counters is 3 : 4.
If 3 of the red counters are removed from Bag C, the ratio of red counters
to yellow counters is 3 : 5.

How many yellow counters are in Bag C?

Answers

Answer 1

Answer:

20

Step-by-step explanation:

The ratio of red : yellow is 3 : 4 = 3x : 4x ( x is a multiplier )

If 3 red counters are removed then

red : yellow = 3x - 3 : 4x = 3 : 5

Expressing in fractional form

[tex]\frac{3x-3}{4x}[/tex] = [tex]\frac{3}{5}[/tex] ( cross- multiply )

5(3x - 3) = 12x

15x - 15 = 12x ( subtract 12x from both sides )

3x - 15 = 0 ( add 15 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

Then

number of yellow counters = 4x = 4 × 5 = 20

Answer:

[tex]x + 1 + x + 3 = 180[/tex]

by vertically opposite angle theorem

[tex]x + x + 1 + 3 = 180[/tex]

[tex]2x + 4 = 180[/tex]

[tex]2x = 180 - 4 = 176[/tex]

[tex]x = \frac{176}{2} [/tex]

[tex]x = 88[/tex]

Answers

Answer:

  y = -0.03x² +12

Step-by-step explanation:

For "tunnel" or "arch" or "bridge" problems, I like to start with the expression ...

  y = 1 - x²

It has a height of 1 and intersects the x-axis at ±1. This can be scaled to give the appropriate height and x-intercepts.

We want the x-intercepts to be ±20, so we can scale this horizontally by a factor of 20:

  y = 1 -(x/20)²

We want the height to be 12, so we can scale it vertically by a factor of 12:

  y = 12(1 -(x/20)²

  y = 12 -12(x²/400)

  y = -0.03x² +12

Julie weighs five watermelons and rounds the weighs to the nearest hundredth which of the weights round to 7.43 pounds

Answers

Options :

7.423 pounds

7.437 pounds

7.413 pounds

7.425 pounds

Answer:

7.425

Step-by-step explanation:

Rounding each option to the nearest hundredth:

The second digit after the decimal point is the hundredth digit, if the next digit (thousandth digit) is more than or equal to 5, then it is rounded to 1 and added to the hundredth digit value, if otherwise, it is rounded to zero.

7.423 = 7.42 (nearest hundredth)

7.437 = 7.44 (nearest hundredth)

7.413 = 7.41 (nearest hundredth)

7.425 = 7.43 (nearest hundredth)
