Quotients are used to represent the division of  numbers

The number is -0.52

Let the number be represented with x.

So, the quotient of a number (x) and 0.2 is -2.6 is represented as:

[tex]\frac x{0.2} = -2.6[/tex]

Multiply both sides of the equation by 0.2

[tex]0.2 * \frac x{0.2} = -2.6 * 0.2[/tex]

Evaluate the quotient, on the left hand side

x = -2.6 * 0.2

Evaluate the product on the right hand side

x = -0.52

Hence, the number is -0.52

To Find : How many different 4-digit personal identification numbers are possible if no digit can be used twice?

Solution :

Since we are given that no digit can be used twice

SO, when one digit is used so next digit will be chosen from the remaining digit an so on .

the digits can be 0,1,2,3,4,5,6,7,8,9

Since these are 10 in number

out of these 10 we need to choose 4 but no digit can be used twice

⇒[tex]_{10}\textrm{C}_1 *_{9}\textrm{C}_1 *_{8}\textrm{C}_1*_{7}\textrm{C}_1  [/tex]

Formula : [tex]_{n}\textrm{C}_r=\frac{n!}{r!(n-r)!}[/tex]

thus using this formula

⇒[tex]\frac{10!}{1!(10-1)!} *\frac{9!}{1!(9-1)!}*\frac{8!}{1!(8-1)!}*\frac{7!}{1!(7-1)!}[/tex]

⇒[tex]\frac{10!}{9!} *\frac{9!}{8!}*\frac{8!}{7!}*\frac{7!}{6!}[/tex]

Answer:

D. x + 15 ≤ 60

Step-by-step explanation:

Let x be the amount you have left to spend after you purchase the shirt.

We must add to x the cost of the shirt, $15.  This gives us x+15.

We only have $60 to spend; this means we can spend anything up to and including $60.  This means we want "less than or equal to."  This gives us the inequality

x+15 ≤ 60

The inequality of the form x + 15 ≤ 60 is the correct choice.

An inequality is a comparison between two non equal expression or terms or numbers.

According to the given question You have a gift card for your favorite clothing store for the amount of $60.

You have found a shirt you want to buy that costs $15 but you don't want to spend more than the amount of the gift card.

Assuming the amount you will have is x dollars.

∴ x + 15 ≤ 60

As x ≤ 60 - 15

x ≤ 45.

Step-by-step explanation:

We will find,

The slope of the function using [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex].

Taking the points (1,40) and (2,55).

Slope = [tex]\frac{55-40}{2-1}[/tex]

i.e. Slope = [tex]\frac{15}{1}[/tex]

i.e. Slope = 15

Substituting the slope and point (1,40) in the equation [tex]y=mx+b[/tex],

We have, [tex]40=15\times 1+b[/tex]

i.e. [tex]b=40-15[/tex]

i.e. b= 25

Thus, the equation of the linear function is [tex]y=15x+25[/tex].

C. [tex](0,-5)[/tex]

Step-by-step explanation:

We have been given a graph of system of equation on coordinate plane. We are asked to find the solution for the system of equations.

We know that we can find solution of a system of linear equations by graphing. The solution of the system is the point, where both lines intersect.

Upon looking at our given graph, we can see that both lines intersect at point [tex](0,-5)[/tex] that is at y-axis.

Therefore, the solution to the system of equations is [tex](0,-5)[/tex] and option C is the correct choice.

Answer:

The slope of the function is 5.

Step-by-step explanation:

Remember that to calculate the slope of any function you just need the equation of the function on slope form: y=mx+c or any two points in the graph that are result of the function, in this case we have a table, and we will use the first two points:

(-4,-16)

(-2.-6)

So the formula for slope is:

[tex]\frac{y2-y1}{x2-x1}[/tex]

We insert the values of our two points:

[tex]\frac{y2-y1}{x2-x1} \\\frac{-6-(-16)}{-2-(-4)}\\\frac{10}{2}\\  Slope=5[/tex]

So the slope of the function is 5.

The diameter of the field is 83 yards.

To find the diameter of a circular field, we can use the formula for the circumference of a circle, which is C = 2πr, where C is the circumference and r is the radius. Given that the circumference of the field is 260.62 yards, we can solve for the radius by dividing the circumference by 2π.

Using the value of π as 3.14, we can calculate:

260.62 / (2 * 3.14) = 41.50 yards

Since the diameter of a circle is twice the radius, the diameter of the field is 2 * 41.50 = 83 yards.

To find the number of hours Carla worked, we'll set up and solve equations based on the information given.

To solve this problem, we'll set up an equation based on the information given.

Let x be the number of hours Carla worked last week and y be the number of hours she worked this week.

According to the problem, 15 more than twice the hours Carla worked last week is the same as three times the hours she worked this week decreased by 15:

2x + 15 = 3y - 15

Next, we'll set up another equation based on the fact that Carla worked the same number of hours each week:

x = y

We can now solve this system of equations to find the value of y, which represents the number of hours Carla worked this week:

Substituting y for x in the first equation: 2y + 15 = 3y - 15

Combining like terms: 15 = y - 15

Adding 15 to both sides: 30 = y

So, Carla worked 30 hours this week.

Answer:18.75 gallons

Step-by-step explanation:

Taking square root on both sides, that becomes 2x - 5 = (+/-) √11

Then:

2x = (+/-)√11 + 5

x = [5 +/- √11 ] / 2

x = 5/2 +/- (√11)/2

That is, x = 5/2 +(√11)/2 and x = 5/2 - (√11)/2

The monthly interest rate on this annuity is approximately 0.4318%.

To find the monthly interest rate on the annuity, we need to use the present value formula for an annuity:

PV = A * (1 -[tex](1+r)^{(-n)[/tex]) / r

Where PV is the present value, A is the monthly payment, r is the monthly interest rate, and n is the total number of payments. In this case, PV = $90,000, A = $850, and n = 15 (since the professor's remaining life expectancy is 15 years).

By plugging in these values and solving for r, we can find the monthly interest rate on the annuity.

$90,000 = $850 * (1 - [tex](1+r)^{-15)[/tex] / r

After solving this equation, we find that the monthly interest rate on this annuity is approximately 0.4318%.

The monthly interest rate is approximately 0.58%.

To determine the monthly interest rate on the annuity, we need to solve for the rate that equates the present value of the annuity payments to the initial payment of $90,000. The payments of $850 are made for the expected life of 15 years, which translates to 180 monthly payments.

The present value (PV) of an annuity can be calculated using the formula:

[tex]PV = Pmt * [(1 - (1 + r)^{-n}) / r][/tex]

Where:
Pmt = $850 (monthly payment)
r = monthly interest rate
n = 180 (total number of payments)

Given PV = $90,000, we need to solve for r:

$90,000 = $850 × [(1 - (1 + r)^-180) / r]

This requires solving the equation iteratively or using a financial calculator, as it's a non-linear equation. By trial and error or using a financial calculator or spreadsheet:

We find that r ≈ 0.0058 or 0.58%

Thus, the monthly interest rate on this annuity is approximately 0.58%.

Answer: 8.

Step-by-step explanation: since the y coordinates are the same number and they are both positive you move to the x coordinates and you subtract them since they are both negative and you'd get a positive 8. Have a Blessed Day! :D

To find the distance between two points in a coordinate plane, you can use the distance formula. In this case, the distance between point G (-4, 1) and point H (-12, 1) is 8 units.

To find the distance between two points in a coordinate plane, you can use the distance formula. The distance formula is derived from the Pythagorean theorem and is given by:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

In this case, the coordinates of point G are (-4, 1) and the coordinates of point H are (-12, 1).

So, substituting the values into the distance formula:

distance = sqrt((-12-(-4))^2 + (1-1)^2)

Simplifying that expression, the distance between point G and point H is 8 units.

Final answer:

When multiplying 0.07 by 1.22, the product is 0.0854. This result is calculated by first multiplying the numbers as whole numbers and then placing the decimal point so that the total number of decimal places in the product matches the sum of the decimal places in the factors.

Explanation:

Therefore, 0.07 multiplied by 1.22 equals 0.0854.

Final answer:

When multiplying 0.07 by 1.22, we first ignore the decimals and multiply 7 by 122 to get 854, and then we place the decimal point so the result has the same number of decimal places as the sum of the factors, resulting in 0.0854.

Explanation:

To find the product of two decimal numbers, you multiply them just as you would with whole numbers, taking care to place the decimal point in the correct position in the final answer. For the multiplication of 0.07 by 1.22, you perform the multiplication ignoring the decimals first, and then place the decimal in the final answer so that the total number of decimal places equals the sum of the decimal places in the factors.

Multiplying 7 by 122 equals 854. Since 0.07 has two decimal places and 1.22 has two decimal places, the product must have four decimal places. Therefore, the correct placement of the decimal point in 854 would be after four digits from the right, which gives us a final answer of 0.0854.

Answer:

Option C. 12 years

Step-by-step explanation:

Let principal amount taken = x

We know the formula of compound interest

Final amount = Principal amount×[tex](1+\frac{r}{n})^{nt}[/tex]

Where r = rate of interest (per year)

n = number of times compounded (annually)

t = time in years (years)

Here we have to find the time in which principal amount is doubled.

From the question r = 6% = .06

n = 1

Principal amount = P

Final amount = 2P

Now we put these values in the formula

[tex]2P=P(1+.06)^{t}[/tex]

[tex]2=(1.06)^{t}[/tex]

Now we take log on both the sides

[tex]log(2)=log(1.06)^{t}[/tex]

0.301 = tlog(1.06)

0.301 = t×(.025)

[tex]\frac{0.301}{0.25}=t[/tex]

t = 12 years.

Option C. 12 years is the answer.
