Is this an example of an Independent Event or a Dependent Event?

Answer: x=3 and y=−2

Step-by-step explanation:

x=−2y−1;4x−4y=20

Step: Solve x=−2y−1 for x:

Step: Substitute−2y−1 for x in 4x−4y=20:

4x−4y=20

4(−2y−1)−4y=20

−12y−4=20(Simplify both sides of the equation)

−12y−4+4=20+4(Add 4 to both sides)

−12y=24

−12y

−12

=

24

−12

(Divide both sides by -12)

y=−2

Step: Substitute−2 for y x=−2y−1:

x=−2y−1

x=(−2)(−2)−1

x=3(Simplify both sides of the equation)

Answer: I believe the answer is around/about 56.55

Step-by-step explanation: C=2πr=2·π·9≈ 56.54 or aound 56.52

Formula: C=2πr

Simplified Equation:

2 x 3.14 x 9= 56.52 - 56.55

Good luck!! I hope this helps! All you have to do is memorize the formula, break down & simplify the numbers and equation and you're golden!!

Edit: I reccomend checking out Khan Academy for math help!

Answer:

C= 56.52

Step-by-step explanation:

[tex]C=\pi d\\[/tex]

[tex]C=(3.14)(18)\\C=56.52[/tex]

If you didn't understand it in mathmatical terms, then here it is in English.

Step 1:

Re-write the formula (Please don't forget to do this step as it is a VERY important step in math)

Step 2:

Once yoou have re-writen the formula, substitute

 In place of [tex]\pi[/tex] write "3.14"

In place of [tex]d[/tex] write 18. I got 18 because the diameter is 2r or twice the amount of the radius. So I added 9. So the equation would be [tex]C=(3.14)*(9+9)[/tex]

[tex]C=(3.14)*(18)[/tex]

Step 3:

Solve for "C" or Circumfrence

[tex]C=(3.14)*(18)\\C=56.52[/tex]

I hope it's clear and understandable. :D

Answer:

C: The shark weighs 2200 pounds more than the whale.

Step-by-step explanation:

So you have to remember first that one ton is equal to 2,000 pounds. Then, we convert tons to pounds (for the whale) to get 4(2,000)=8,000 pounds. So, the whale weighs 8,000 pounds. The shark weighs 10,200 pounds, so all you have to do now is do 10,200-8,000 to get 2,200 pounds.  So, the answer is C.

Answer:1. $3- 4 bottles, 1 bottle = 4/3 , 7 bottles= 28/3

2. 40 pounds=$32, 1 pound= $8/10

3. Per bag= 3/2, 7bags= 21/2

4. Per book = $3, 21 books= $63

5. Per bracelet = 0.25 cents, 11 bracelets = 2 dollars 75 cents

Answer:

106250

Step-by-step explanation:

Ok so we know that in the first quarter the company sold 125000 units to people. But then suddenly they start losing 5%. Since we are told there are 3 quarters, we would have to do 5% plus 5% plus 5%, which amounts to 15% total lost in the three quarters. What we do now is we technically subtract that to 125000, so the equation would be 125000 minus 15%, and when you either use a calculator to help or your own mind, you get 106250 units sold.

Answer:

$110

Step-by-step explanation:

First, find how many cubic yards of dirt will be dug up:

Use the volume formula, V = lwh

Plug in the values:

V = lwh

V = (5)(4)(8)

V = 160

Now, divide this by 15 to find how many trips it will take:

160/15

= 10.67

Round this to the nearest whole number:

10.67

= 11

Multiply this by 10 to find the price:

11(10)

= 110

So, it will cost $110 to have all the dirt hauled away

The cost will be equal to $110.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Step-by-step explanation:

You are finding the whole

0.7 × 20 = 14

or

70% of 20 = 7/10 x 20 = 7/10 x 20/1 = 140/10

140/10

140/10 = 14/1
