Answer:

4  (9 x + 11) is an equivalent expression for the perimeter that shows the side length of the square is  (9 x + 11).

Step-by-step explanation:

Here, given The perimeter of the square  = (36 x+44)

Now,as we know :

PERIMETER OF SQUARE = 4 x ( SIDES)

Simplifying the perimeter expression.

Take 4 common out of the expression (36 x+44), we get:

(36 x+44) =  4 (9 x + 11)

⇒ Perimeter of the square  =  4 x  (9 x + 11)

⇒4 x ( SIDES) = 4 x (9 x + 11)

⇒ Each Side = (9 x + 11)

Hence, 4 x (9 x + 11) is an equivalent expression for the perimeter that shows the side length of the square is  (9 x + 11).

Answer:

4

Step-by-step explanation:

7-3=4

then i just messed around with putting numbers to the 4th and got 4

The question asks for a number which, when raised to the 7th power and divided by the same number raised to the 3rd power, results in 256. By understanding the rules of exponents, we find that the number is 4 because 4^4 equals 256.

To solve this problem, it's important to know that when you divide two numbers with the same base and different exponents, you subtract the exponents. So, a number to the 7th power divided by the same number to the 3rd power equals that number to the (7-3)th = 4th power.

Therefore, the question is asking for a number which to the 4th power equals 256. The fourth root of 256 is 4 because 4^4 equals 256. So the answer is 4.

Answer:

$907.489

Step-by-step explanation:

Cost of camera : $824.99

Tax = 10%

tax on camera = 824.99 x 10 /100 = 82.499

total amount to be paid = cost + tax

$824.99 + $82.499 = $907.489

Answer:

$907.49

Step-by-step explanation:

Figure out what 10% of 824.99 is. You should get 82.499 which you round up to the nearest hundredth because this is money which gives you 82.50.

824.99+82.50=907.49

Answer:

C) 100

Step-by-step explanation:

line AC intersects line DB,

hence ∠AEB and ∠DEC are opposite angles and thus

∠AEB = ∠DEC

5x-10 = 4x+12   (subtract 4x from both sides)

5x - 4x - 10 = 12

x - 10 = 12    (add 10 to both sides)

x = 12 + 10 = 22 degrees

∠DEC = 4x+12

= 4(22) + 12

= 88 + 12

= 100 degrees

Answer:

total=$60

Step-by-step explanation:

Including bill there's a total of 5 people

take what each person paid, $12, and multiply by the number of people

$12(5)=$60

The total bill at the restaurant was $60, calculated by multiplying the amount each person paid ($12) by the number of people (5).

In this Mathematics problem, Bill and his four friends, for a total of five people, decided to equally divide the restaurant bill. Each person paid $12. In order to find the total bill, we must multiply the amount each person paid by the number of people. This means, we multiply $12 by 5, which gives us a total bill of $60.

Answer:

The answer is G = 20 - m/18, but none of the answers given is correct.

Step-by-step explanation:

1. Let's review the information given to us to help Lulu to answer the question correctly:

Capacity of the gas tank of Lulu's car = 20 gallons

Lulu can travel 216 miles using 12 gallons

2. Which linear equation represents the number of gallons of gas, G, left in the tank after driving m miles?

G = number of gallons left in Lulu's car

m = Miles driven by Lulu

miles per gallon = 216/12 = 18 miles per gallon

Now, we can write the linear equation, this way:

G = Capacity of the gas tank of Lulu's car - miles driven/miles per gallon

Replacing with the values we know:

G = 20 - m/18

Let's assume Lulu drives 180 miles, using our linear equation, we have:

G = 20 - 180/18

G = 20 - 10 = 10 gallons left

Let's assume Lulu drives 54 miles, using our linear equation, we have

G = 20 - 54/18

G = 20 - 3 = 17 gallons left

Answer:

Step-by-step explanation:

Diagram 1

Area = b*h/2 = 4y*(y+5)/2 = 2y*(y+5)= 2y² + 10y

Diagram 2

Area = side*side = y * y = y²

the area of ​​the triangle exceeds the rectangle by 39 cm².

2y² + 10y - y² = 39

y² + 10y = 39

y² + 10y -39 = 0

y² +13y - 3y - 3*13 = 0

y(y+13) -3(y+13)=0

(y+13)(y-3) = 0

y  + 13 = 0  will not come as length couldn't be in negative

y - 3 = 0

y = 3 cm

Diagram 2:

Perimeter = 4*side = 4*y = 4*3 = 12 cm

Therefore, the solution of the given equation is [tex]13[/tex].

Applying the 2020 US tax brackets, Sarina would owe $4,842.50 in federal taxes on her $42,000 income.

The amount of federal taxes that Sarina owes on her $42,000 income can be determined by referring to the tax brackets provided by the IRS. In 2020, the federal income tax rates for individuals are as follows:

According to these brackets, Sarina would pay 10% on her first $9,875 and 12% on the remaining amount up to $40,125. Any income she earned over that up to $85,525 would be taxed at 22%. Given that Sarina made $42,000, she falls into the second tax bracket. Therefore, her tax would be calculated as follows:

By adding these amounts together, we can conclude that Sarina would owe $4,842.50 in federal taxes for that year.

Sarina, a single filer earning $42,000 annually, would first deduct the standard deduction to calculate taxable income. Her taxable income of $28,350 would be taxed at 10% for the first $11,000 and at 12% for the next $17,350. The total federal tax owed by Sarina would be $3,182.

The amount Sarina owes in federal taxes depends on the tax rates applied to income brackets. For a single taxpayer earning $42,000 a year, we look at the given tax brackets to calculate the tax owed based on the progressive tax system in the United States.

Since Sarina's income is within the second bracket ($11,001-$44,725), her income will be taxed at different rates for different portions of her income.

First, we subtract a single filer's standard deduction to determine her taxable income. Let's assume the current standard deduction is similar to the $13,650 mentioned.

Calculate taxable income:

Total Income: $42,000

Standard Deduction: $13,650

Taxable Income: $42,000 - $13,650 = $28,350

Now, we split the taxable income according to the tax brackets:

First $11,000 are taxed at 10%: $1,100

Next $17,350 ($28,350 - $11,000), taxed at 12%: $2,082

Total tax owed = $1,100 + $2,082 = $3,182.

The complete question is:

Sarina made $42,000 in the calendar year. How much does she owe in federal taxes?

Rate : 10% , 12% , 22% , 24% , 32% , 35%  37%

Both Andrew and Elena are wrong. The actual value of 2^28 equals 268,435,456.

Step-by-step explanation:

Elena was right when she said exponents mean repeated multiplication but she accidentally calculated the value of 28^2 instead of 2^28. 2^28 means that the number 2 should be multiplied with itself for 28 times.

2^2 means 2 multiplied by 2 equals 4. 2^3 means 2 multiplied by 2 and then multiplied by 2 again which equals 8. Similarly, if you multiply 2 with itself 28 times you will get a value of 268,435,456 (two hundred and sixty-eight million, four hundred and thirty-five thousand, four hundred and fifty-six). So Andrew and Elena will have 268,435,456 coins after 28 days.
