Answer:

[tex]A = w^2 + 7w[/tex]   is the rule for the area of a rectangle.

A = 120 sq ft, when it’s width is 8 ft.

Step-by-step explanation:

Here, let us assume the width of the rectangle =  w

So, the length here = Width +  7 ft = (w +  7) ft

Now, AREA of a RECTANGLE = Length x Width

Substituting here the values of length and width, we get:

A = (w) x (w +  7) [tex]= w^2 + 7 w[/tex]

[tex]\implies A = w^2 + 7w[/tex]

The above function is the rule for the area of a rectangle.

Given: w = 8  ft

To find the area: put w  = 8 in [tex]A = w^2 + 7w[/tex]

We get: A  = 8²  +  7(8)  

                 = 64 +  56  = 120

or, A  = 120 sq ft.

Hence, area = 120 sq ft, when it’s width is 8 ft.

Answer:

6.2% of last month's income was spent on office expenses

Step-by-step explanation:

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

Office's income last month = $ 315,600

Expenses last month = $ 19,567.20

2. What percent of last month's income was spent on office expenses?

To calculate this percent, we use this fraction:

Expenses last month/Office's income last month

Replacing with the real values:

19,567.20/315,600 = 6.2%

6.2% of last month's income was spent on office expenses

Final answer:

Tom's real estate office spent 6.2% of its income on office expenses last month. This was calculated by dividing the expenses by the income and then multiplying by 100.

Explanation:

To determine what percent of last month's income was spent on office expenses for Tom's real estate office, you need to use the formula for calculating the percentage of expenses relative to income. The formula is:

Percentage of Expenses = (Expenses ÷ Income) × 100

Now, we were given that the office's income last month was $315,600 and the expenses were $19,567.20. Substituting these numbers into our formula gives us:

Percentage of Expenses = ($19,567.20 ÷ $315,600) × 100

Percentage of Expenses = (0.062 × 100)

Percentage of Expenses = 6.2%

Therefore, 6.2% of last month's income was spent on office expenses.

The speed in feet per second is 247.5

The parachutist will fall 4950 feet during 20 seconds.

Step-by-step explanation:

Given,

Speed during free fall = 75 meters per second

It is given that,

1 meter = 3.3 feet

75 meter = 75*3.3 = 247.5 feet

Therefore;

Speed during free fall in feet = 247.5 feet per second

Now,

1 second = 247.5 feet

20 seconds = 247.5*20 = 4950 feet

Fall during 20 seconds = 4950 feet

The parachutist will fall 4950 feet during 20 seconds.

The parachutist's speed in freefall, converted to feet per second, is 247.5 feet per second. In 20 seconds of free-fall, the parachutist would fall a total of 4950 feet.

The parachutist's speed in free-fall is given as 75 meters per second. We know that 1 meter is equivalent to approximately 3.3 feet. So, to convert the speed from meters per second to feet per second, we multiply the speed in meters per second by 3.3. This gives us a speed of 75 * 3.3 = 247.5 feet per second.

Then, to find out how many feet the parachutist will fall during 20 seconds of free fall, we multiply the speed in feet per second by the time in seconds, which results in 247.5 * 20 = 4950 feet.

Answer:

y= -1 , -3 , -5

Step-by-step explanation:

2x-3y=9

2x-9=3y

2x-9/3=y

when x=0

y= -9/3

y= -3

when x= 3

y = 2(3)-9/3

  = 6-9/3

  = -3/3

y = -1

when x= -3

y = 2(-3)-9/3

y= -6-9/3

y= -15/3

y= -5

To solve the equation 2x-3y=9 for y in terms of x, firstly move the '2x' on right side of the equation to get -3y = -2x + 9. Multiply each term by -1 to get 3y = 2x - 9. And then divide each term by 3 to get y = (2/3)x - 3.

In order to solve the equation 2x-3y=9 for y in terms of x, we first isolate y. The first step would be to move '2x' part to the right side of the equation. It becomes like this: -3y = -2x + 9 or simply, 3y = 2x - 9 where we multiplied every part of the equation by -1. Now, the next step is to get rid of '3' that is multiplying 'y'. For this, you divide entire equation by '3'. Hence, y = (2/3)x - 3. So, the equation for y in terms of x is y = (2/3)x - 3.

The width of the rectangle is 10 inches and the length is 50 inches. The area of the rectangle is 500 square inches.

Let's denote the width of the rectangle as w. Since the length of the rectangle is five times its width, we can write the length as 5w. The formula for the perimeter of a rectangle is P = 2(l + w), so we can set up the equation 120 = 2(5w + w). Solving this equation, we find that the width is 10 inches and the length is 50 inches.

To find the area of the rectangle, we use the formula A = l * w. Plugging in the values for length and width, we get A = 50 * 10 = 500 square inches. Therefore, the area of the rectangle is 500 square inches.

Answer:

In Grade 8, 17% of students liked running

Step-by-step explanation:

Although this table is incomplete, there are still enough information to answer.

First, we need to be aware that the data here is written in decimal numbers, which is another way to write percentages.

In other words, 100% equals to 1, which is to say that if we multiply decimal number with 100 we'll get the percentage:

0.39 = 39%

0.04 = 4%

Another important thing to establish is that the value of decimal number DOES NOT mean the number of people, it only suggests the ratio:

0.26 does not mean 26 people etc.

Knowing this, from this incomplete table, we see that 0.17 students from grade 8 liked running. And now we know that 0.17 equals to 17%, which makes B the correct answer.

Answer: 785.5

Step-by-step explanation:

Final answer:

To solve 2 divided by 1571, recognize it as a fraction 2/1571, which cannot be simplified. Perform long division, adding zeros as necessary, to find its decimal representation, which will be very small.

Explanation:

To solve 2 divided by 1571 step by step without a calculator, you can follow these steps:

Understand that this division represents a fraction, 2/1571.

Recognize that this fraction cannot be simplified further since 2 and 1571 have no common factors other than 1.

To find the decimal form, you can perform long division. However, since 2 is much smaller than 1571, the decimal will start with 0. As 2 cannot be divided by 1571, in the first step of long division, you would put a 0 to the right of the decimal point in your answer.

Next, you would need to add a 0 to the right of 2 (making it 20), since 1571 still cannot go into 2. Then, determine how many times 1571 can go into 20, which will still result in 0, and so on, adding zeros and comparing until you reach a desired level of precision.

This process will yield a very small decimal, indicating that 2/1571 is a fraction much less than 1.

Answer: a= -4

Step-by-step explanation:

Final answer:

To solve the equation 4a+5=2+3.25a, isolate the variable 'a' on one side of the equation. The solution is a = -4.

Explanation:

To solve the equation 4a+5=2+3.25a, we need to isolate the variable 'a' on one side of the equation.

Step 1: Subtract 3.25a from both sides of the equation:

4a - 3.25a + 5 = 2

0.75a + 5 = 2

Step 2: Subtract 5 from both sides of the equation:

0.75a = 2 - 5

0.75a = -3

Step 3: Divide both sides by 0.75 to solve for 'a':

a = -3/0.75

a = -4

Therefore, the solution for the equation 4a+5=2+3.25a is a = -4.

Answer:

$31.20

Step-by-step explanation:

Angela will get an amount of $31.2 as the interest at the end of 1 year.

Simple interest is defined as the interest obtained over the principal amount on a certain rate.

Given that Angela puts $520 in an account that earns 6% per year.

Principal or initial amount = $520

Rate of interest = 6% = 6 / 100 = 0.06

We have to calculate the amount of interest.

Interest amount = $520 × 0.06

                           = $31.2

Hence the amount of interest that Angela get at the end of the year is $31.2.

Explanation:

Option a: p ∨ q

p ∨ q means that either p is true or q is true or both are true.

Hence, Option a is not the correct answer.

Option b: p ∧ q

p ∧ q means that both p and q are true.

Hence, Option b is not the correct answer.

Option c: p → q

p → q means that if p is true, then q is also true.

Hence, Option c is the correct answer.

p ↔ q means that if p is true, then q is true. If q is true, then p is true.

Hence, Option d is not the correct answer.

Thus, p → q is the correct option.
