Note: 1 inch = 2.54 cm is an exact converion, while 1 mile=1.6km is only approximate.

Using conversion
1 inch=2.54 cm
1 mile = 1760*3*12 = 63360 in = 160934.4 cm 
If 1 inch = 1 mile, then 
2.54 cm : 1 mile = 1.609344 km
1 cm : 0.6336 km   (exactly), or
1 cm : 0.6 km (approximately)

Using both conversions:
1 inch = 2.54 cm : 1 mile = 1.6 km
=>
2.54 cm : 1.6 km
1 cm : 1.6/2.54=0.6299 km (approximately), or
1 cm : 0.6 km (approximately)

Vadim26 [7]
I'm not sure but I think I may have the answer to number 9
It says she uses 3 draws for shirts and wants to find out the percentage. Percentage is normally out of 100% so we do 100÷4 (we divide by 4 because there are 4 drawers)
100÷4=25. So now it says she uses three drawers for her shirts so we need to do 25x3=75 and all you do with that is put it in percent. The answer is 75%
P.S I am not entirely sure that this is correct but I wanted to help ❤

A very weak university is on and off probationary status with the accrediting agency. A different procedure is used in July and
tino4ka555 [31]

Answer:

0.3425 = 34.25% probability it will be off probation in February 2020

Step-by-step explanation:

We have these desired outcomes:

Off probation in July 2019, with 0.25 probability, then continuing off in January, with 1 - 0.08 = 0.92 probability.

Still in probation in July 2019, with 1 - 0.25 = 0.75 probability, then coming off in January, with 0.15 probability.

What is the probability it will be off probation in February 2020?

p = 0.25*0.92 + 0.75*0.15 = 0.3425

0.3425 = 34.25% probability it will be off probation in February 2020

4x + 9 = 2x + 15 .. I need help
valkas [14]

Answer:

x = 3

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

4x + 9 = 2x + 15

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Subtract 2x on both sides:                    2x + 9 = 15
  2. Subtract 9 on both sides:                      2x = 6
  3. Divide 2 on both sides:                          x = 3

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    4(3) + 9 = 2(3) + 15
  2. Multiply:                               12 + 9 = 6 + 15
  3. Add:                                     21 = 21

Here we see that 21 does indeed equal 21.

∴ x = 3 is the solution to the equation.

Winston's soup recipe makes 6 servings and uses 4 carrots and 2 potatoes.how many Winston needs for 15 servings?
Natalija [7]
Ggalaxy, your question is quite convoluted, but I'll answer it anyway. 15/6=2.5. 2.5x4=10 and 2.5x2=5. 10+5=15 vegetables (This includes the 4 carrots and 2 potatoes.)
