Find an expression for the number of squares in the nth pattern of the sequence. I noticed that the number of squares you add in each pattern it depends on the pattern number (see image) but I don't know how to get the expression. ​

The computer costs $304 now.

Step-by-step explanation:

Given,

Cost of computer = $400

First discount = 20%

Amount of discount = 20% of $400

Amount of discount = [tex]\frac{20}{100}*400=\frac{8000}{100}[/tex]

Amount of discount = $80

Price after first discount = 400-80 = $320

Additional discount = 5%

Amount of additional discount = 5% of price after first discount

Amount of additional discount = [tex]\frac{5}{100}*320=\frac{1600}{100}[/tex]

Amount of additional discount = $16

Final cost = 320-16 = $304

The computer costs $304 now.

Answer:

Maya = $1260

Emily = $5040

Step-by-step explanation:

2740+3560 =6300

M + (4M) = 6300

5M=6300

M=6300/5

M=1260

E=5040

Maya has $1260, and Emily has $5040 in the end. Maya gives $1480 to Emily.

Maya has $2740, and Emily has $3560.

We're looking for the amount Maya gives to Emily so that Emily ends up with 4 times as much as Maya.

Let M be the amount Maya gives to Emily.

Emily ends up with 4 times Maya's amount:

Emily's amount = 4 * Maya's amount

$3560 + M = 4 * ($2740 - 4M

Simplify:

$3560 + M = $10960 - 4M

$3560 + M + 4M = $10960

5M = $10960 - $3560

5M = $7400

Divide by 5 to solve for M:

M = $7400 / 5

M = $1480

So, Maya gives $1480 to Emily.

To find how much each girl has in the end:

Maya: $2740 - $1480 = $1260

Emily: $3560 + $1480 = $5040

Maya has $1260, and Emily has $5040 in the end.

Answer:

The radius of Astrodome is 355.09 foot,

The Area of Astrodome is 395919.146 square foot .

Step-by-step explanation:

Given as :

The circumference of Astrodome = 2230 foot

∵ The circumference of circular shape = 2 × [tex]\pi[/tex] × radius

where  [tex]\pi[/tex] = 3.14

So, The circumference of Astrodome = 2 × [tex]\pi[/tex] × radius

Or, 2230 foot = 2 × 3.14 × radius

Or, 2230 foot = 6.28 × radius

∴ radius = [tex]\dfrac{2230}{6.28}[/tex]

I.e radius = 355.09 foot

Now,

∵The area of circular shape = [tex]\pi[/tex] × radius²

So, The area of Astrodome = [tex]\pi[/tex] × radius²

Or, The area of Astrodome = 3.14 × radius²

Put the value of radius = 355.09 foot

So , The area of Astrodome = 3.14 × (355.09)²

or, The area of Astrodome = 3.14 × 126088.9

∴  The area of Astrodome = 395919.146 square foot

Hence , The radius of Astrodome is 355.09 foot, and The Area of Astrodome is 395919.146 square foot . Answer

__

For this problem, it isn't always easiest to work the questions in order. It is best to start with the angles easiest to find from those given.

  b and 144° are a linear pair, so b = 180° -144° = 36°

  a and b are alternate interior angles, so a = b = 36°

  2d and 144° are corresponding angles, so d = 144°/2 = 72°

  e is the apex angle of an isosceles triangle with base angles 36°, so is 180° -2(36°) = 108° = e

  f and 164° are a linear pair, so f = 180° -164° = 16°

  g and f are complementary, so g = 90° -16° = 74°

  g+h is a vertical angle with 144°, so is congruent to that. h = 144° -74° = 70°

  c is the base angle of an isosceles triangle with b as the vertex angle. That means c = (180° -36°)/2 = 72°

Answer:

The system cannot be solved by a unique cost for each soldier

Step-by-step explanation:

The correct question is

The denarius was a unit of currency in ancient Rome. Suppose it costs the Roman government 10 denarius per day to support 3 legionaries and 3 archers. It only costs 3 denarius per day to support one legionary and one archer. Use a system of linear equations in two variables.

Can we solve for a unique cost for each soldier?

Let

x-------> the cost of a legionary per day

y-------> the cost of an archer per day

we know that

[tex]3x+3y=10[/tex]

isolate the variable y

subtract 3x both sides

[tex]3y=10-3x[/tex]

Divide by 3 both sides

[tex]y=-x+\frac{10}{3}[/tex] ------> equation A

[tex]x+y=3[/tex]

isolate the variable y

subtract x both sides

[tex]y=-x+3[/tex] ------> equation B

Remember , If two lines are parallel, then their slopes are equal

In this problem Line A and Line B are parallel lines, because their slopes are equal.

we know that that the solution of the system of equations is the intersection point both graphs

If the lines are parallel, then the lines don't intersect

Answer:

8 CD's for $56.99 is better value than 3 CD's for $22.99.

Step-by-step explanation:

We are given that,

Cost of 8 CD's is $56.99 and cost of 3 CD's is $22.99.

Now, to determine which is the better value, we will find the cost of 1 CD in both the cases. The case which will give cost per CD less will represent the better value.

CASE 1 :

Cost of 8 CD's = $ 56.99

So, cost of 1 CD = $ 56.99 ÷ 8 = $ 7.12  (approx.)

CASE 2 :

Cost of 3 CD's = $ 22.99

∴ Cost of 1 CD = $ 22.99 ÷ 3 = $ 7.66 (Approx.)

So, the CD's are available in cheaper rates in the first case in comparison to second case.

So, 8 CD's for $56.99 is better value than 3 CD's for $22.99.

Answer:

The unit cost of 8 CDs for $56.99 is $7.12 and the unit cost of 3 CDs for $22.99 is $7.66.

And the better value is of 8 CDs for $56.99.

Step-by-step explanation:

Given:

8 CDs for $56.99 or 3 CDs for $22.99.

Now, to find the unit cost to determine which is better value.

By using unitary method we find it:

So, to get the unit cost of 8 CDs for $56.99:

If 8 CDs cost $56.99.

Then, 1 CD cost = [tex]56.99\div 8=\$7.12.[/tex]

Thus, the unit cost = $7.12.

Now, to get the unit cost of 3 CDs for $22.99:

If 3 CDs cost $22.99.

Then, 1 CD cost = [tex]22.99\div 3=\$7.66.[/tex]

Thus, the unit cost = $7.66.

Now, on comparing we determine the better value is of 8 CDs for $56.99.

Therefore, the unit cost of 8 CDs for $56.99 is $7.12 and the unit cost of 3 CDs for $22.99 is $7.66.

And the better value is of 8 CDs for $56.99.

Answer: 24times

Step-by-step explanation:

Formula for the volume of a cylinder                         = πr²h

Volume of the cone                                                      = 1/3πr²h

Therefore the volume of the cylinder               = 22/7 x 10² x 20

                                                                     = 22/7 x 10 x 10 x 20

                                                                                = 6285.71cm³

Therefore , the volume of the cone             = 1/3 x 22/7 x 5² x 10

                                                                     = 1/3 x 22/7 x 5 x 5 10

$650

Step-by-step explanation:

the child stole $500 then the shopkeeper gave him change of $150 that equals to the amount of money the shopkeeper lost.

working....

$500+$150=$600

Final answer:

The shopkeeper lost a total of $500 due to the child stealing $500, buying items worth $350, and receiving $150 in change.

Explanation:

The question involves determining the total amount of money the shopkeeper lost due to a theft. When the child stole $500 from the cash register and then used some of this money to buy items worth $350, the shopkeeper effectively lost that amount due to the child not legitimately paying for the goods. Furthermore, the child received $150 in change when they used the stolen money to pay for the items. Therefore, the total money lost by the shopkeeper is the sum of the cost of the goods taken and the change given out, which amounts to $350 + $150, equating to a total loss of $500.

Answer:

The number of years in which house value goes up is 145 years .

Step-by-step explanation:

Given as :

The initial purchased value of the house = p = $179,300,00

The value of house goes up every years at the rate = r = 4%

Let The number of years in which house value goes up = t  years

The value of the house after t years = $A = $5197,230,002

Now, According to question

The value of the house after t years = The initial purchased value of the house × [tex](1+\dfrac{\textrm rate}{100})^{\textrm time}[/tex]

I.e A = $p × [tex](1+\dfrac{\textrm r}{100})^{\textrm t}[/tex]

Or,$5197,230,002 = $17930000 × [tex](1+\dfrac{\textrm 4}{100})^{\textrm t}[/tex]

Or, [tex]\dfrac{5197,230,002}{179,300,00}[/tex] = [tex](1+\dfrac{\textrm 4}{100})^{\textrm t}[/tex]

Or, 289.86 = [tex](1.04)^{t}[/tex]

Now, taking Log both side

So, [tex]Log_{10}[/tex]289.86 = [tex]Log_{10}[/tex] [tex](1.04)^{t}[/tex]

or, 2.462 = t ×  [tex]Log_{10}1.04

or, 2.462 = t × 0.01703

∴ t = [tex]\dfrac{2.462}{0.01703}[/tex]

I.e t = 144.56 ≈ 145

So, Number of years = t = 145 years

Hence The number of years in which house value goes up is 145 years . Answer

To determine the number of years it will take for the value of Isaac's house to reach $5,197,230.002 with an annual appreciation rate of 4%, use the compound interest formula. Solving for the number of years, the approximate result is 84 years.

Isaac purchased a house for $179,300. Every year, the value of the house increases by 4%. To determine the number of years after purchase that the value of Isaac's house will reach $5,197,230.002, we can use the formula for compound interest:

FV = PV × (1 + r)ⁿ

We need to solve for n in the equation:  

First, isolate the exponential expression:

Next, apply the natural logarithm to both sides to solve for n:

So, the value of Isaac's house will reach $5,197,230.002 approximately 84 years after purchase.
