The number of 1/8-acre plots in a 3/4-acre garden is 6.

The question is about dividing the total area of a garden into smaller plots and finding out how many plots there will be. Here, the total size of the garden is given as 3/4 acre and each plot is 1/8 acre in size. To find out how many 1/8-acre plots make 3/4 of an acre, we perform a division: 3/4 divided by 1/8. This is the same as multiplying 3/4 by the reciprocal (the 'flipped' fraction) of 1/8, which is 8/1. So, the calculation is 3/4 * 8/1 = 24/4 = 6. Therefore, there are 6 1/8-acre plots in a 3/4-acre garden.

Answer:

375 adult tickets and 302 student tickets

Step-by-step explanation:

s+a=677

a=s+73

s+s+73=677

2s+73=677

2s=604

s=302

a= 375

Final answer:

Explanation on finding the number of adult tickets sold for a school play when the total number of tickets sold and the relationship between adult and student tickets are known.

Explanation:

The total number of tickets sold for the school play was 677.

Let x be the number of adult tickets sold.

It is given that there were 73 fewer student tickets than adult tickets, so the number of student tickets sold would be x - 73.

Therefore, x + (x - 73) = 677.

Solving this equation, we find that 2x - 73 = 677, 2x = 750, x = 375.

So, 375 adult tickets were sold.

The money he will save if he earns $120.00 is $90.00.

Step-by-step explanation:

Given:

In the figure is the ratio of the savings and the earnings.

Now, to find out that how much savings will be if Miguel earns $120.00.

We need to get the percentage of the ratio of the earning and saving.

So, according to the table:

If he earns $10.00 then he saves $7.50.

[tex]\frac{7.50}{10}\times 100[/tex]

[tex]=0.75\times 100[/tex]

[tex]=75[/tex]

So, if Miguel earns $10.00 he save the 75% of it.

If he earns $50.00 then he saves $37.50.

As we calculate the percentage as the above process then the saving is 75% of the earning.

And, if he earns  $150.00 and save $112.50 then it is also the 75% of the earning as mentioned above.

Now, to find the saving of the earning $120.00.

So, it will be 75% of the earning as we observe in the above case:

75% of $120.00

[tex]\frac{75}{100}\times 120[/tex]

[tex]=0.75\times 120[/tex]

[tex]=90[/tex]

Therefore, the money he will save if he earns $120.00 is $90.00.

Answer:

The complete length is 115 cm.

Step-by-step explanation:

Given:

If 20%of a length is 23 cm.

Now, to find the complete length.

Let, the complete length be [tex]x[/tex].

So, according to question:

20% of [tex]x[/tex] = 23 cm

[tex]\frac{20}{100} \times x=23[/tex]

[tex]0.20\times x=23[/tex]

[tex]0.20x=23[/tex]

Dividing both sides by 0.20 we get :

[tex]x=115[/tex]

Therefore, the complete length is 115 cm.

To find the complete length when 20% is 23 cm, divide 23 cm by 0.20 to get 115 cm as the total length.

If 20% of a length is 23 cm, we want to find out what the complete length is. To do so, we recognize that 20% is the same as saying 20 per 100 or 0.20 in decimal form. If 0.20 of the length is 23 cm, it means that 23 cm represents 0.20 of the total length. We can set up the equation like this:

0.20 * Total Length = 23 cm

To find the Total Length, we divide both sides of the equation by 0.20:

Total Length = 23 cm / 0.20

Total Length = 115 cm

Therefore, the complete length is 115 cm.

For this case we must find an expression equivalent to:

Thus, an equivalent expression is:

[tex]-72y-18x + 54\\-18x-72y + 54[/tex]

Answer:

[tex]-18x-72y + 54[/tex]

Final answer:

To find equivalent expressions, we combine like terms in the given expression 36y - 18x - 108y + 54.

Explanation:

To find expressions equivalent to 36y - 18x - 108y + 54, we can combine like terms.

First, combine the y terms: 36y - 108y = -72y.

Next, combine the x terms: -18x.

Combining the constants, we have: 54.

Putting it all together, the equivalent expression is: -18x - 72y + 54.

Answer:

4.  B

5.  C

Step-by-step explanation:

4.

We can say the 5 angles of the Pentagon PQRST equals 540 degrees.

We see that Angle P and Angle T are 90 degrees each.

R is given as 100

Q and S are same, let it be "x"

Now we can write an equation:

P + Q + R + S + T = 540

90 + x + 100 + x + 90 = 540

Solving for x, we get:

2x + 280 = 540

2x = 540 - 280

2x = 260

x = 260/2

x = 130

Angle Q is equal to x, so that is 130

Correct answer is B

5.

When 2 parallel lines are cut by transversal, the corresponding angles are equal.

The 60 degree angle given and the angle adjacent (beside) to angle x are same. So we can say that is equal to 60 degrees as well.

This 60 degree angle and x form a straight line. The degree measure of a straight line (or a straight angle) is 180 degrees. Thus we can write:

60 + x = 180

Now, we solve for x:

60 + x = 180

x = 180 - 60

x = 120

The correct answer is C

First side: 12 feet, second side: 16 feet

Step-by-step explanation:

We know that the second side is 4 feet longer than the first side. If the first side is x, then the second side is x+4

b) The total amount of the border is 28 feet, so we can say that first side+second side=28, or

x+(x+4)=28

2x+4=28

2x=24

x=12 feet is the first side

x+4 = 16 feet is the second side

We can check that 12 feet + 16 feet = 28 feet as stated by the problem

To make a minimum profit of $100 with each snack priced at $4.00, a total of 47 snacks need to be sold at the concession stand. This includes 22 snacks to cover the total cost of $86.56 and an additional 25 snacks to achieve the profit goal.

The question is about finding out how many snacks need to be sold at a concession stand to achieve a minimum profit. To get the answer, we first need to determine how many snacks would make up the total cost, and then calculate how many additional snacks would be necessary to attain the profit goal.

Given that each snack at the concession stand costs $4.00 and that the total cost of the snacks is $86.56, we can find out how many snacks were initially purchased by dividing the total cost by the price of each snack: $86.56 ÷ $4.00 = 21.64 snacks. Since we can't sell a fraction of snack, we round up to 22 snacks to cover the total cost.

To calculate the number of additional snacks needed to attain a $100 profit, we divide the profit goal by the price of each snack: $100 ÷ $4 = 25 snacks.

Therefore, to cover the total cost and also make a minimum profit of $100, the concession stand needs to sell 22 snacks for the cost and additional 25 snacks for the profit, totaling 47 snacks altogether.

(10,9)

Step-by-step explanation:

Chloe made 4 three-point shots and 5 two-point shots.

Let's solve this problem using a system of equations.

Let x be the number of three-point shots Chloe made and y be the number of two-point shots she made.

We have the following equations:

x + y = 9 (equation 1)

3x + 2y = 22 (equation 2)

From equation 1, we can solve it for x:

x = 9 - y

Substitute this value of x into equation 2:

3(9 - y) + 2y = 22

27 - 3y + 2y = 22

-y = -5

y = 5

Substitute this value of y back into equation 1:

x + 5 = 9

x = 4

Therefore, Chloe made 4 three-point shots and 5 two-point shots.

It will take 7.30 years until Dale can by his mask

Step-by-step explanation:

Compound continuous interest can be calculated using the formula:

[tex]A=Pe^{rt}[/tex] , where

Dale invests $6000 in an account at 9.5% interest compounded continuously. The mask costs $12000. We need to find how long will it take Dale until can buy this mask

∵ Dale invests $6000

∴ P = 6000

∵ The interest rate is 9.5% ⇒ compounded continuously

∴ r = 9.5% = 9.5 ÷ 100 = 0.095

∵ The mask costs $12000

∴ A = 12000

Substitute these values in the formula above

∵ [tex]12000=6000e^{0.095t}[/tex]

- Divide both sides by 6000

∴ [tex]2=e^{0.095t}[/tex]

- Insert ㏑ for both sides

∴ [tex]ln(2)=ln(e^{0.095t}[/tex])

- Remember that [tex]ln(e^{n})=n[/tex]

∴ [tex]ln(2)=0.095t[/tex]

- Divide both sides by 0.095

∴ t = 7.29628611

∴ t = 7.30 ⇒ to the nearest hundredth year

It will take Dale 7.64 years to save enough money to buy the mask we can use the method of compound interest.

To find how long it will take Dale to save enough money to buy the mask, we can use the following formula for compound interest:

A = P * e^(rt)

where:

A is the final amount

P is the principal amount

r is the interest rate

t is the time in years

We know that A = $12000, P = $6000, and r = 9.5%. We need to solve for t.

12000 = 6000 * e^(0.095t)

e^(0.095t) = 2

ln(2) = 0.095t

t = ln(2) / 0.095

t = 7.64

Algebra tiles are a useful tool to simplify expressions. Depending on their shape and decoration, they represent different parts of the expression. Review your tiles and match them to the four given expressions carefully.

The question pertains to Algebra and specifically, matching a simplified algebraic expression to a set of tiles. The exact matching algebraic expression cannot be determined as the set of tiles isn't provided in the question but here's how you would approach this kind of problem:

If you're using algebra tiles, squares typically represent x², rectangles portray x, and small squares depict constants like 2. The color or decoration of a tile may indicate a positive or negative value. For example, a square with '- ' could mean '-x²'.

So if you've got a square with '- ', a rectangle without a decoration, and two small plain squares, your expression should be '-x² - x + 2'. If the rectangle had a '-', your expression would be '-x² + x + 2' instead.
