A small pool is being drained. There are 1,320 gallons of water remaining in the pool after 2 minutes and 1,040 gallons after 9 minutes.

Answer:

16.67

166.7

1667

16670

Step-by-step explanation:

Any number to the zeroth power is 1, so the first one is 1 x 16.67, which equals to 16.67

10 to the first power is just 10, so multiply 10 x 16.67 for the second one. This equals 166.7

10 to the second power is 10 x 10 or 100, so multiply 100 x 16.67, which is 1667.

10 to the third power is 10 x 10 x 10 or 1000, so multiply 1000 x 16.67, which is 16670.

Basically, for each one, starting with 10 to the first power, move the decimal to the right one place.

Answer:

3/5

Step-by-step explanation:

We want to find 3/4 of 4/5.

The keyword of tells us that we need to multiply. Therefore:

[tex]\frac{3}{4}\times\frac{4}{5}[/tex]

Multiply:

[tex]=12/20=3/5[/tex]

So, 3/4 of 4/5 is 3/5.

We can confirm this by converting them to decimals.

4/5 is 0.8.

3/4 is 0.75.

0.75 or 75% of 0.8 is indeed 3/5 or 0.6.

An isosceles triangle is a triangle with 2 equal sides and 1 un equal side. So just draw a triangle with those measurements.

Answer:

cookie

Step-by-step explanation:

Answer: I think that the answer is cookies.

Step-by-step explanation:

The least common denominator for the fractions would be 840.

Bread: 2/8 x 105/105 = 210/840

Pie: 1/7 x 120/120 = 120/840

Cookies: 1/3 x 280/280 = 280/840

Cake: 1/5 x 168/168 = 168/840

Least to greatest:

120/840, 168/840, 210/840, 280/840

That is how I know that the cookies use the most oil.

I got this information from Calculator Soup so this isn’t all of my information.

Answer:

The  final price of the smart phone if you use the store credit card is $339.5

Step-by-step explanation:

Given;

original price of the smart phone = $679

initial discount = 35%

additional discount if you use the store credit card = 15%

total discount of the smart phone if you use the store credit card

= 35% + 15% = 50%

The final price of the smart phone, if you use the store credit card is given as;

P = 0.5 X $679

P = $339.5

Therefore, the  final price of the smart phone if you use the store credit card is $339.5

hi

you must find f°g  

so apply g then f.

g(x) =  2x²+2x-7

f(x) =  2x-7

so  f(gx) =    2  ( 2x²+2x-7) - 7

                 =   4x²+4x-14-7

                  =  4x²+4x - 7

Answer:

Something like M=80-(7x4)

Step-by-step explanation:

Answer:

The solution set is { } or ∅ ⇒ empty set

Step-by-step explanation:

∵ 2x + 10 < 10

→ Subtract 10 from the two sides of the inequality

∵ 2x + 10 - 10 < 10 - 10

∴ 2x < 0

→ Divide both sides by 2

∴ [tex]\frac{2x}{2}[/tex] < [tex]\frac{0}{2}[/tex]

∴ x < 0

∴ The solutions are all the negative numbers

∵ x ∈ N

∵ N is the set of Natural numbers

→ The natural numbers start at 1 and include all positive whole numbers

∴ N = {1, 2, 3, 4, 5, ..............}

∵ N does not contain any negative numbers

∴ The solution set is an empty set ⇒ ∅

∴ The solution set is { } or ∅

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

4(x - 1) = 2(6 - 2x)

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 4 does indeed equal 4.

∴ x = 2 is a solution of the equation.

8x³•(x-3)

Step-by-step explanation:

LET ME EXPLAIN, THAT HOW I GET THE ANSWER

STEP 1

((4•(x2))-9)

———————————————— ÷ (2x+3) ÷ (22x2-12x)

(((2•(x2))-9)+9)

STEP 2

((4•(x2))-9)

2x2

STEP 4

4x2 - 9

Simplify ———————

2x2

MY EXPLANATION THAT HOW TO GET THE SQUARE:

Trying to factor as a Difference of Squares:

4.1 Factoring: 4x2 - 9

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 4 is the square of 2

Check : 9 is the square of 3

Check : x2 is the square of x1

Factorization is : (2x + 3) • (2x - 3)
