D. Subtraction property of equality; n = 15

Step-by-step explanation:

Given equation that shows the cost of n basketballs uniforms,

C = 40n + 260

According to the question,

Total cost = $ 860,

⇒ 40n + 260 = 860

Using subtraction property of equality, subtract 260 on both sides,

⇒ 40n = 860 - 260

⇒ 40n = 600

Using division property of equality, divide both sides by 40.

⇒ n = [tex]\frac{600}{40}[/tex] = 15.

Hence, 15 uniforms were purchased.

i.e. Option D is correct.

Answer:6.7

Step-by-step explanation:5.2+6.3=11.5 then you do -12 divided by 2.5 and get -4.8 then you add the answers together but that won’t work because different signs subtract and you get positive 6.7

To evaluate the expression (5.2+6.3) - 12 ÷ 2.5, you first perform the division. Then, substitute the result and add the numbers inside the parentheses. Finally, subtract the result from the addition.

To evaluate the expression (5.2+6.3) - 12 ÷ 2.5, we start by performing the division. 12 ÷ 2.5 equals 4.8. Now, we substitute this result into the expression, so the expression becomes (5.2+6.3) - 4.8. Next, we add the numbers inside the parentheses together, giving us 11.5. Finally, we subtract 4.8 from 11.5, resulting in 6.7.

Final answer:

The slope of the line passing through (0, 5) and (-12, 2) is calculated using the slope formula and is found to be 1/4.

Explanation:

The slope of the line passing through the points (0, 5) and (-12, 2) can be calculated using the formula slope (m) = (rise)/(run), where 'rise' is the change in the y-values and 'run' is the change in the x-values. To find the slope, we subtract the y-value of the second point from the y-value of the first point and divide by the subtraction of the x-value of the second point from the x-value of the first point: m = (5 - 2) / (0 - (-12)) = 3 / 12 = 1/4. Therefore, the slope of the line is 1/4.

James has 55 dimes in the bag

Step-by-step explanation:

The given is:

We need to find how many dimes James has

Assume that the number of nickels is x and the number of

dimes is y in the bag

∵ There are x nickels in the bag

∵ There are y dimes in the bag

∵ There are 77 coins in the bag

∴ x + y = 77 ⇒ (1)

∵ 1 nickel = 5 cents

∴ The value of nickles in the bag = 5x cents

∵ 1 dime = 10 cents

∴ The value of dimes in the bag = 10y cents

∵ The total value of coins is $6.60

∵ 1 dollar = 100 cents

∴ $6.60 = 6.60 × 100 = 660 cents

∴ 5x + 10y = 660 ⇒ (2)

Now we have a system of equations to solve it

Multiply equation (1) by -10 to eliminate y

∵ -10x - 10y = -770 ⇒ (3)

- Add equations (2) and (3)

∴ -5x = -110

- Divide both sides by -5

∴ x = 22

Substitute the value of x in equation (2) to find y

∵ 22 + y = 77

- Subtract 22 from both sides

∴ y = 55

∴ The number of dimes is 55

Answer:

This is correct I did it on schoology

Step-by-step explanation:

To calculate the total number of homes in Lora's community, the number of flyers distributed (630) is divided by the percentage of homes that received flyers (35%), resulting in a total of 1800 homes.

To find the total number of homes in Lora's community, we need to set up a proportion where the number of flyers delivered represents 35% of all homes. Since Lora distributed flyers to 630, that is 35% of the total homes. Using the percentage formula:

Total Homes = Distributed Flyers / Percentage of Homes

So, in this case, it would be:

Total Homes = 630 / 0.35

Dividing 630 homes by 0.35 (35% as a decimal) gives us:

Total Homes = 1800

Therefore, there are 1800 homes in Lora's community.

Answer:

The numbers are 23 and 24

Step-by-step explanation:

Let

x ----> the first positive consecutive integer

x+1 ----> the second positive consecutive integer

we know that

The product of the two consecutive positive integers is 552

so

The algebraic expression that represent this situation is

[tex]x(x+1)=552[/tex]

Convert to expanded form

[tex]x^2+x-552=0[/tex]

Solve the quadratic equation by graphing

The roots of the equation are

[tex]x_1=-24[/tex] ----> the number cannot be negative

[tex]x_2=23[/tex]

see the attached figure

therefore

[tex]x=23\\x+1=24[/tex]

The numbers are 23 and 24

To find two consecutive positive integers whose product is 552, set up the equation x(x + 1) = 552, expand and solve the quadratic equation.

To find two consecutive positive integers whose product is 552, we can set up the equation x(x + 1) = 552, where x represents the smaller integer.

Expanding the equation, we get x^2 + x - 552 = 0. This is a quadratic equation, and we can solve it by factoring or using the quadratic formula.

Factoring the quadratic equation, we find that (x - 23)(x + 24) = 0. So the two consecutive positive integers are 23 and 24.

p=11 packets were purchased

Step-by-step explanation:

30+11p=151

11p=121

then

121/11

so

p=11

Hope I understood the question :/

Answer:

Step-by-step explanation:

I believe the correct answer is that Andrew's Math Teacher purchased 11 packets of 10 tests each, meaning that the total number of test would be 110. I got this by subtracting the $30 entrance fee from the $151. After doing this we are left with $121. I then divided the $121 by the cost per packet and I was left with 11 packets. Since every packet contains 10 tests I multiplied that by the number of packets to get the final answer... 110 tests purchased.

The exponential function with a horizontal asymptote y = -7 that passes through the points (0, -6) and (1, 6) is:

y = [tex]e^{(ln(13)x)} - 7[/tex].

To find an exponential function with a horizontal asymptote y = -7 that passes through the points (0, -6) and (1, 6), we can use the general form of an exponential function:

[tex]y = A * e^{(kx)} + C[/tex]

where A is the initial value, k is the growth/decay rate, e is the base of the natural logarithm (approximately 2.71828), x is the independent variable, and C is the y-coordinate of the horizontal asymptote.

Step 1: Determine the value of C (the y-coordinate of the horizontal asymptote):

Since the asymptote is y = -7, we set C = -7.

Step 2: Use the given points to find A and k:

For point (0, -6):

-6 = A * e⁰ - 7

-6 + 7 = A

A = 1

For point (1, 6):

6 = 1 * [tex]e^{(k*1)[/tex] - 7

13 = [tex]e^{k[/tex]

Step 3: Solve for k:

Take the natural logarithm of both sides: ln(13) = k

Step 4: Write the exponential function:

The exponential function with a horizontal asymptote y = -7 that passes through the points (0, -6) and (1, 6) is:

y = [tex]e^{(ln(13)x)} - 7[/tex].

This function will have a horizontal asymptote at y = -7 and pass through the given points (0, -6) and (1, 6).

The mean absolute deviation is a measure of variation in a dataset, not its center. It helps indicates how spread out the data is from the mean value.

The mean absolute deviation is not a measure of center,instead, it is a measure of variation. The center of a data set is typically represented by measures like the mean, median, or mode. These describe the common, central value in the dataset.

Conversely, the mean absolute deviation is a statistical tool used for understanding the dispersion or variation in a set of values. It gives an average of the absolute differences between each data point and the mean of the data set. This helps identify how spread out the data is from the mean.

Answer:

The values are x = 0° or x = 60°

Step-by-step explanation:

Given:

[tex]\cos x + \frac{1}{\sqrt{3} }\times \sin x = 1[/tex]

Let it be in the form of

[tex]a\cos x + b\sin x = 1[/tex] such that

a = 1

[tex]b=\frac{1}{\sqrt{3} }[/tex]

We have

[tex]\sqrt{(a^{2}+b^{2} )}=\sqrt{(1^{2}+(\frac{1}{\sqrt{3} }) ^{2} )}\\=\sqrt{\frac{4}{3}}\\=\frac{2}{\sqrt{3} }[/tex]

Now, Dividing both the side by [tex]\frac{2}{\sqrt{3} }[/tex] we get

[tex]\frac{\sqrt{3} }{2}\cos x + \frac{1}{2}\sin x =\frac{\sqrt{3} }{2}\\[/tex]

We Know

[tex]\sin 60 =\frac{\sqrt{3} }{2}\\and\\\cos 60 = \frac{1}{2}[/tex]

Now by replacing with above values we get

[tex]\sin 60\times \cos x + \cos 60\times \sin x = \frac{\sqrt{3} }{2}\\[/tex]

Also we have formula

[tex]\sin A\times \cos B + \cos A\times \sin B = \sin (A+B)[/tex]

By applying the above Formula we get

[tex]\sin (60+x)=\frac{\sqrt{3} }{2}\\[/tex]

Also ,

[tex]\sin (60)=\frac{\sqrt{3} }{2}\\and\\\sin (120)=\frac{\sqrt{3} }{2}[/tex]

Comparing we get

 60 + x = 60   or  60 + x = 120

∴ x = 0°               ∴ x = 120 - 60 = 60°    

Therefore, the values are x = 0° or x = 60° i.e between 0° to 360°
