Which fractions are the same value as 16 divided by-3

Answer:

70 students

Step-by-step explanation:

If 40% of all students in Mrs. Well's class got an A, and 28 students got an A, that means that 28 = 40%

To find the total number of students, we need to find 100%

40% = 28

Divide by 4

10% = 7

Multiply by 10

100% = 70

So there are 70 students in Mrs. Well's class.

Hope this helps you! :D

Answer:

(x + i) (x - i)

Step-by-step explanation:

The expression x^2 + 1 is a sum of squares, which means that it cannot be factored using real numbers. However, it can be factored using complex numbers.

To factor x^2 + 1, we can use the fact that i^2 = -1, where i is the imaginary unit.

We can rewrite x^2 + 1 as:

x^2 + 1 = x^2 - (-1)

Now, we can use the difference of squares formula to factor x^2 - (-1):

x^2 - (-1) = (x + i)(x - i)

Therefore, the factored form of x^2 + 1 is:

(x + i)(x - i)

Answer:

\(\bold{f(x) = 375(2.5)^{-x}+ 33}\)

Step-by-step explanation:

An exponential function of form f(x) = ba^(-x) + c has a horizontal asymptote of y = c as x approaches infinity, and a y-intercept of (0, b + c). We can use the given information to set up a system of equations and solve for the unknowns.

The horizontal asymptote is given as y = 33, so we have:

c = 33

The y-intercept is given as (0, 408), so we have:

b + c = 408

Substituting c = 33, we get:

b + 33 = 408

b = 375

So the function we're looking for is of the form:

\(\bold{f(x) = 375a^{-x}+ 33}\)

To find a, we use the fact that the function passes through P(2, 93):

93 = 375a^(-2) + 33

60 = 375a^(-2)

a^2 = 375/60

a^2 = 6.25

a = \(\sqrt{6.25 } =2.5\)

Therefore, the exponential function that satisfies the given conditions is:

\(\bold{f(x) = 375(2.5)^{-x}+ 33}\)

Answer:

0.125 cubic feet

Step-by-step explanation:

Since the container has a shape of a cube with a measure of its side 0.5 ft, then;

Volume of the container, V = \(s^{2}\)

where s is the measure of its side.

s = 0.5 ft, then;

V = \((0.5)^{3}\)

    = 0.125

V = 0.125 cubic feet

The cubic feet of slime that would fit in the container is 0.125.

Answer:

\(1\frac{1}{2}\) <2<2 \(\frac{6}{11}\)

Step-by-step explanation:

\(1\frac{1}{2}\) is less than 2 is less than 2 \(\frac{6}{11}\)

\(\frac{33}{22} < \frac{44}{22} < \frac{56}{22}\)

The length of Marisa's garden is 10

The given parameters are:

Perimeter = 32 feet

Width = 6 feet

The perimeter is calculated as:'

Perimeter = 2 * (Length + width)

So, we have

2 * (Length + 6) = 32

Divide by 2

Length + 6 = 16

Subtract

Length = 10

Hence, the length of Marisa's garden is 10

Answer:

30 mph

Step-by-step explanation:

Let d = distance (in miles)

Let t = time (in hours)

Let v = average speed driving to the airport (in mph)

⇒ v + 15 = average speed driving from the airport (in mph)

Using:  distance = speed x time

\(\implies t=\dfrac{d}{v}\)

Create two equations for the journey to and from the airport, given that the distance one way is 18 miles:

\(\implies t=\dfrac{18}{v} \ \ \textsf{and} \ \ t=\dfrac{18}{v+15}\)

We are told that the total driving time is 1 hour, so the sum of these expressions equals 1 hour:

\(\implies \dfrac{18}{v} +\dfrac{18}{v+15}=1\)

Now all we have to do is solve the equation for v:

\(\implies \dfrac{18(v+15)}{v(v+15)} +\dfrac{18v}{v(v+15)}=1\)

\(\implies \dfrac{18(v+15)+18v}{v(v+15)}=1\)

\(\implies 18(v+15)+18v=v(v+15)\)

\(\implies 18v+270+18v=v^2+15v\)

\(\implies v^2-21v-270=0\)

\(\implies (v-30)(v+9)=0\)

\(\implies v=30, v=-9\)

As v is positive, v = 30 only

So the average speed driving to the airport was 30 mph

(and the average speed driving from the airport was 45 mph)

Let s represent the speed on the return trip

So, The initial speed will be (s-15)

Equation of time:

\( \boxed{ \tt \: time = \frac{distance}{speed} }\)

return time + initial time = 1 hr

\( \sf\frac{18}{s} + \frac{18}{s - 15} = 1\)

Answer: The value of x is 49.

Step-by-step explanation:

To find the value of x, you will first need to cross multiply the fractional variables together.

5x - 80 = 3x + 18

Then, move the numerical term 80 to the right side of this equation and add it to 18.

5x - 80 = 3x + 98

Move 3x to the left side of the equation and subtract it this time to the variable 5x.

2x = 98

Finally, you divide both of the equation's sides by 2 and you will get 49.

x = 49

When you actually add x to this problem, you would get 33/55.

49 - 16/49 +6 = 33/55

You can then simplify 33/55 and get the same answer 3/5.

3/5

Therefore, the value of x for this variable equation with the fractions would be equal to x = 49. Hope this helps!

The values of a and b using the factor theorem for the polynomial f(x), we set f(1) and f(-1) equal to zero. Solving the resulting system of equations, we find that a = 12 and b = -1.

To find the values of a and b using the factor theorem, we need to use the given factors (x - 1) and (x + 1) and the fact that they are roots of the polynomial f(x).
The factor theorem states that if (x - c) is a factor of a polynomial, then f(c) = 0. Therefore, we can set x = 1 and x = -1 in the polynomial f(x) to get two equations.
First, let's substitute x = 1 into f(x):
f(1) = (1)^3 + a(1)^2 + b(1) - 12
f(1) = 1 + a + b - 12
Next, let's substitute x = -1 into f(x):
f(-1) = (-1)^3 + a(-1)^2 + b(-1) - 12
f(-1) = -1 + a - b - 12
Since (x - 1) and (x + 1) are factors, f(1) and f(-1) must equal zero. Therefore, we can set the two equations equal to zero and solve for a and b:
1 + a + b - 12 = 0
-1 + a - b - 12 = 0
Rearraning the equations, we have:
a + b = 11
a - b = 13
Now, we can solve this system of equations. Adding the two equations, we get:
2a = 24
a = 12
Substituting the value of a into one of the equations, we find:
12 - b = 13
b = -1
Therefore, the values of a and b are 12 and -1 respectively.

Mrs. Jackson needs to sell a total of $20,000 worth of products to earn $3,000 a month with a 15% commission on everything she sells.

Given that,

Mrs. Jackson needs to earn $3,000 a month.

The commission percentage is 15%.

Let us assume the amount be x.

To calculate how much Mrs. Jackson needs to sell to earn $3,000 a month, we can use the formula for commission-based earnings:

Earnings = Commission Rate × Sales

We know that Mrs. Jackson earns a 15% commission on everything she sells, and her goal is to earn $3,000 a month.

Let x be the total sales amount she needs to achieve her goal.

Earnings = 0.15x

According to the problem, she needs to earn $3,000, so we can set up the equation:

0.15x = $3,000

Now, to find x, we need to isolate it on one side of the equation. We can do that by dividing both sides by 0.15:

x = $3,000 / 0.15

x = $20,000

So, Mrs. Jackson needs to sell a total of $20,000 worth of products to earn $3,000 a month with a 15% commission on everything she sells.

For given function function f(x)=-x+3-2, the domain is x > -3 and the range is y ≤ 2. So, correct option is D.

The function f(x)=-x+3-2 is a linear function in the form y=mx+b, where m is the slope and b is the y-intercept. In this case, the slope is -1 and the y-intercept is 1. Therefore, the graph of the function is a straight line that intersects the y-axis at (0,1) and has a slope of -1, meaning that it decreases by 1 for every 1 unit increase in x.

The domain of the function is the set of all possible values of x for which the function is defined. Since there are no restrictions on the value of x in the equation f(x)=-x+3-2, the domain is all real numbers, or (-∞, ∞).

The range of the function is the set of all possible values of y that the function can output. In this case, the lowest possible value of y occurs when x approaches positive infinity, and the highest possible value of y occurs when x approaches negative infinity. Therefore, the range is all real numbers less than or equal to 2, or y ≤ 2.

So, the domain is x ∈ (-∞, ∞) and the range is y ≤ 2. Alternatively, the domain can also be expressed as x > -3, since that is the minimum value of x at which the function is defined.

Correct option is D.
