Answer:

f = 0.30(x)

Step-by-step explanation:

Let x = # of dollars

Let f = final amount

Note that 30% is the same as 30/100, which in decimal form is 0.30

Set the equation.

Each pair of shoes costs x amount, in which it is decreased by 30%, which leads to the cost in f amount.

The cost of the bench is 425 dollars.

Step-by-step explanation:

Let x represent the garden table.

Let y represent the bench.

x + y = 804

x = y - 46

Use the substitution method.

y - 46 + y = 804

2y - 46 = 804

Add 46 to both sides.

2y = 850

Divide both sides by 2.

y = 425

Answer:

120√6

Step-by-step explanation:

Simplify the 5√8 to 2√2

simplify the √18 to 3√2

so it would be √3 * 2√2 * 5 * 2√2 * 3√2

when a square root of an expression is multiplied by itself:

√3 * 2 * 2* 5 * 2 * 3√2

so as we calculate it, 2 * 2* 5 * 2 * 3 = 120 and √2 * √3 = 6

[tex]\sqrt3\\2\sqrt2\\5\sqrt8=5\sqrt{4\cdot2}=5\sqrt4\cdot\sqrt2=5(2)\sqrt2=10\sqrt2\\\sqrt{18}=\sqrt{9\cdot2}=\sqrt9\cdot\sqrt2=3\sqrt2\\\\\sqrt3\cdot2\sqrt2\cdot5\sqrt8\cdot\sqrt{18}=\sqrt3\cdot2\sqrt2\cdot10\sqrt2\cdot3\sqrt2\\\\=(2\cdot10\cdot3)(\sqrt3\cdot\sqrt2\cdot\sqrt2\cdot\sqrt2)=60\sqrt{3\cdot2}\cdot\sqrt{2\cdot2}\\\\=60\sqrt6\cdot\sqrt4=60\sqrt6\cdot2=(60\cdot2)(\sqrt6)\\\\=\boxed{120\sqrt6}[/tex]

Answer:

Answer is: 5^ -8  *  5^4 =  5^-4

Step-by-step explanation:

To simplify : 5^ -8  *  5^4

This can also be written as :

5^ -8  *  5^4 = 1/5^8 * 5^4

or 5^ -8  *  5^4 = 5^4 / 5^8

or 5^ -8  *  5^4 = 5^(4 - 8)

or 5^ -8  *  5^4 = 5^-4

Hence we got 5^ -8  *  5^4 =  5^-4

Answer:

402.88mm³

Step-by-step explanation:

To find the answer to this, we need to find the total area of the coin and then the size of the inner coin.

As this is a cylinder, the formula is:

[tex]\pi r^{2} h[/tex]

So lets find the area of the whole coin.

The radius is 11.5 and height is 2.2

[tex]\pi * 11.5^{2} * 2.2 = 914.05[/tex]

Now, the area of the inner circle:

Radius is 8.6 and height is 2.2:

[tex]\pi * 8.6^{2} * 2.2 = 511.17[/tex]

Now to find the area of the silver ring in the coin, you subtract the inner circle measurement from the whole coin measurement:

914.05 - 511.17 = 402.88

So the volume of the outer ring is 402.88mm³

Answer: [tex]36 cm^2[/tex]

Explanation:

Since here ABCD is the parallelogram.

Where E is the mid point of the line segment BC.

And, F is the intersection point of the segments AE and BD,

Also,  Area of △BEF is 3 [tex]cm^2[/tex].

We have to find Area of parallelogram ABCD.

Since,In  ΔBEF  and ΔACD,

∠ADF=∠EBF ( because AD ║ BE )

∠DFA = ∠BFE (vertically opposite angle)

Thus, By AA similarity postulate,

[tex]\triangle BEF \sim \triangle ACD[/tex],

Thus, [tex]\frac{area of \triangle ADF }{area of \triangle BFE} =(\frac{AD}{BE})^2[/tex]

But, AD = 2 BE,

Therefore,  [tex]\frac{area of \triangle ADF }{area of \triangle BFE} =(\frac{2BE}{BE})^2[/tex] = 4/1

Thus, area of Δ ADF = [tex]12 cm^2[/tex]

Similarly, [tex]\triangle ADB \sim \triangle BAE[/tex]

Now, let the area of the triangle AFB = x [tex]cm^2[/tex]

Thus, x + 12 = 2(x+3) ( because the area of the ΔADB = 2(area of ΔBAE) )

⇒ x = 6 [tex]cm^2[/tex]

Therefore, area of ΔAFB= 6 [tex]cm^2[/tex]

⇒ area of ΔABD = 12 + 6 = 18 [tex]cm^2[/tex]

By the definition of diagonal of parallelogram,

Area of parallelogram ABCD = 2× area of Δ ABD= 2 × 18 = 36 [tex]cm^2[/tex]

Answer:

Area = 2x^2 -5x-12

Step-by-step explanation:

Area = length * width

Area = (2x+3) * (x-4)

We will use the FOIL technique  to multiply the terms.

First:  2x*x = 2x^2

Outer:  2x* -4 = -8x

Inner:  3*x = 3x

Last = 3* -4  = -12

Add the 4 terms together:  2x^2 -8x+3x -12   = 2x^2 -5x-12

Area = 2x^2 -5x-12

Answer: 2x^2 - 5x - 12

Step-by-step explanation: The correct answer is 2x^2 - 5x - 12. To find the area of a rectangle you multiply the length by the width. So you multiply (2x + 3)(x - 4) using the FOIL method.

First train's speed is 363 mph

Second train's speed is 356.1 mph

=====================================

Explanation:

x = speed of first train, y = speed of second train

x+y = 719.1 because the two speeds add to this value (sum means result of addition)

x = y+6.9 due to the fact that the first train (x) is faster than the second train (y) by 6.9 mph

Use substitution to find that...

x+y = 719.1

y+6.9+y = 719.1 <--- replace x with y+6.9

2y+6.9 = 719.1

2y = 719.1-6.9 <--- subtract 6.9 from both sides

2y = 712.2

y = 712.2/2 <--- divide both sides by 2

y = 356.1

now use this y value to find x

x = y+6.9

x = 356.1+6.9

x = 363

The speed of the first train is 363 mph and the speed of the second train is 356.1 mph. To find these, we solved the equation 2x + 6.9 = 719.1, where x represents the speed of the slower train.

To solve this problem, we will use algebra to set up equations based on the information given. Let's denote the speed of the second train as x miles per hour. Accordingly, the speed of the first train is described as x + 6.9 miles per hour, since we are told it is 6.9 mph faster than the second train. The sum of their speeds is given to be 719.1 mph. Therefore, we can write the following equation to find the speeds of each train:

Hence, the speed of the second train is 356.1 mph. Now to find the speed of the first train we add 6.9 mph to the speed of the second train:

So the speed of the first train is 363 mph, and the speed of the second train is 356.1 mph.

Answer:

m = [tex]\frac{3n}{4}[/tex]

Step-by-step explanation:

given 4m + 2n = 5n ( subtract 2n from both sides )

4m = 3n ( divide both sides by 4 )

m = [tex]\frac{3n}{4}[/tex]

Answer:

m = 3/4 n

Step-by-step explanation:

4m+2n=5n

Subtract 2n from each side

4m +2n-2n = 5n-2n

4m = 3n

Divide by 4

4m/4 = 3n/4

m = 3/4 n

Answer:

$800 is the answer because you subtract 7200 from 8000 and you get 800

Final answer:

To earn an $8,000 commission at a rate of 4%, the car dealer needs to increase his total sales by $20,000, from $180,000 last month to $200,000 this month.

Explanation:

The car dealer wishes to increase his commission from $7,200 to $8,000. Since he earns a 4% commission on all cars sold, we first need to determine how much his sales were last month. To do this, we divide his commission for the last month by the commission rate:

Last month's sales = Commission / Commission rate = $7,200 / 0.04 = $180,000

To earn $8,000 this month, we need to find the total sales required:

This month's sales = Desired commission / Commission rate = $8,000 / 0.04 = $200,000

To find the increase in total sales needed, we subtract last month's sales from this month's sales target:

Required increase in sales = This month's sales - Last month's sales = $200,000 - $180,000 = $20,000

Answer:

a.  He started with $50 in the the account.

b.  The account grow by $10 dollars each week

c see graph

Step-by-step explanation:

y = 50 + 10x

We can rewrite this as

y = 10x+50

This is in the form y = mx+b

where m = 10 which is the slope and b =50 which is the y intercept

The y intercept = 50 is the starting value or the value when x = 0

a.  He started with $50 in the the account.

The slope is how much it grows by as x grows.  As x increase by 1 , y will grow by the slope or 10, so  the account will grow by 10 each week.

b.  The account grow by $10 dollars each week

c see graph

1363>= x

He can spend no more than $1363 on everything else

Step-by-step explanation:

If he has 2000 dollars to spend in total, that will go on one side of the inequality.  Everything he spends goes on the other.  2000 is the maximum he can spend.  He is going to sped 637 on an airline ticket plus x on other expenses.

2000>= 637+ x

Subtract 637 from each side

2000-637 >= 637-637 +x

1363>= x

To find out how much your brother can spend for everything else, subtract the cost of the airplane ticket from his total savings. Your brother can spend up to $1,363 for everything else.

To find out how much your brother can spend for everything else, we need to subtract the cost of the airplane ticket from his total savings. Let's say his total savings is $2,000 and the cost of the airplane ticket is $637. We can write the inequality as:

2000 - 637 ≤ x

Simplifying the inequality, we have:

1363 ≤ x

Therefore, your brother can spend up to $1,363 for everything else.
