Answer: To calculate how much the treats will cost, you need to multiply the cost per pound of the treats by the number of pounds Devyn wants to buy.

Cost = Price per pound x Number of pounds

Cost = 2.45 x 3.7

By performing this calculation we can get that the treats will cost : 2.45 x 3.7 = 9.095

So the treats will cost $9.095.

Given sequence:

If t(n) = 200, we can try to find the value of n:

There is no integer solution, since 32 < 40 < 64 or 2⁵ < 40 < 2⁶, the value of n should be between 5 and 6.

The sequence should include integer numbers, so there is no solution.

Given function:

Solve for x if f(x) is 200:

Answer:

1.  No

[tex]\textsf{2.} \quad x=\dfrac{\ln 40}{\ln 2} \approx5.32\;(\sf 2\;d.p.)[/tex]

Step-by-step explanation:

Given sequence:

[tex]t(n)=5 \cdot 2^n[/tex]

To determine if the sequence has a term with a value of 200, substitute t(n)=200 into the equation and solve for n:

[tex]\implies 5 \cdot 2^n=200[/tex]

[tex]\implies 2^n=40[/tex]

[tex]\implies \ln 2^n=\ln 40[/tex]

[tex]\implies n\ln 2=\ln 40[/tex]

[tex]\implies n=\dfrac{\ln 40}{\ln 2}[/tex]

[tex]\implies n=5.3219280...[/tex]

In a sequence, n is a positive integer.  Therefore, it is not possible for the sequence to have a term with the value of 200, as when t(n)=200, n is not a positive integer.

Given function:

[tex]f(x)=5 \cdot 2^x[/tex]

To determine if the function has an output of 200, substitute f(x)=200 into the function and solve for x:

[tex]\implies 5 \cdot 2^x=200[/tex]

[tex]\implies 2^x=40[/tex]

[tex]\implies \ln 2^x=\ln 40[/tex]

[tex]\implies x=\dfrac{\ln 40}{\ln 2}[/tex]

[tex]\implies x=5.3219280...[/tex]

Therefore, it is possible for the function to have an output of 200 when:

[tex]x=\dfrac{\ln 40}{\ln 2}[/tex]

On solving the provided question, we can say that Principal = 21,000, interest = 0.4% and time = 4 yrs => SI = $336

Simple interest is calculated by dividing the principal by the interest rate, the passage of time, and other elements. The formula used in marketing is simple return = principal + interest + hours. Using this approach, interest may be calculated most easily. The most common way to calculate interest is as a percentage of the principal balance. If he borrows $100 from a friend and agrees to pay it back with 5% interest, for instance, he will only pay his proportion of the 100% interest. $100 (0.05) = $5. You must pay interest when you borrow money and charge interest when you lend it. The majority of the time, interest is calculated as an annual percentage of the loan balance. This proportion is referred to as the loan's interest rate.

here,

Principal = 21,000

interest = 0.4%

time = 4 yrs

SI = Principal X Interest X time / 100

SI = 21000*0.4*4/100 = $336

Answer: Morgan will arrive at Town B at 5pm - 36 minutes = 4:24pm if she cycled at an average speed of 25km/h.

Step-by-step explanation: To solve this problem, we can use the formula: distance = speed x time.

We know that at 15km/h, Morgan reaches Town B at 6pm, and at 20km/h, she reaches Town B at 5pm.

We can use this information to find the distance between Town A and Town B and the time it takes to travel this distance at 25 km/h.

First, let's find the distance between Town A and Town B:

distance = speed x time

distance = 15 km/h x time

time = distance / 15 km/h

time = (distance / 15) hours

Since we know that when Morgan travel at 15km/h to reach town B at 6pm, we can use the time to calculate the distance:

time = 6pm - 5pm = 1hour

distance = 15 km/h x 1 hour = 15 km

Next, we can use this distance and the new speed 25km/h to calculate the arrival time:

time = distance / speed

time = 15 km / 25 km/h = 0.6 hours = 36 minutes

So, she will arrive at Town B at 5pm - 36 minutes = 4:24pm if she cycled at an average speed of 25km/h.

Please note that this calculation is assuming that the distance between Town A and Town B is a constant, and assuming that the time of arrival at 15km/h and 20km/h are accurate.

The domain is x < 2 or x ≥ 3 and the range y > - 3

The domain of a function is the interval of valid inputs to the function.

The range of a function is the interval of valid outputs to the function.

Since we have the function

To find the domain of the function, we see that the values of x are between x < 2 or x ≥ 3.

So, the domain is x < 2 or x ≥ 3.

To find the range of the function, since

f(x) = -x/2 - 2 if x < 2 and f(x) = 2x - 4 if x ≥ 3.

Using the first function f(x) = -x/2 - 2 if x < 2 and substituing x = 2, we have that

f(2) = -2/2 - 2 = - 1 - 2 = -3

Since f(x) cannot be less than f(2), then

f(x) > - 3

So, y > - 3

Also, using the second function f(x) = 2x - 4 if x ≥ 3. and substituting x = 3 into the equation since this is the minimum value of x, then

f(3) = 2(3) - 4

= 6 - 4

= 2

Since this is the minimum value of f(3) = 2

So, y > 2

Since y > -3 and y > 2, combining both expressions, we have that

Step-by-step explanation:

triangle shows angles are 38°, (7x+1)°, (10x+9)°(outside of the triangle)

total angle of the triangle is 180°

then

        38°+ (7x+1)°+ [180-(10x+9)°] = 180°

Simplifying

38 + (7x + 1) + [180 + -1(10x + 9)] = 180

Reorder the terms:

38 + (1 + 7x) + [180 + -1(10x + 9)] = 180

Remove parenthesis around (1 + 7x)

38 + 1 + 7x + [180 + -1(10x + 9)] = 180

Reorder the terms:

38 + 1 + 7x + [180 + -1(9 + 10x)] = 180

38 + 1 + 7x + [180 + (9 * -1 + 10x * -1)] = 180

38 + 1 + 7x + [180 + (-9 + -10x)] = 180

Combine like terms: 180 + -9 = 171

38 + 1 + 7x + [171 + -10x] = 180

Remove brackets around [171 + -10x]

38 + 1 + 7x + 171 + -10x = 180

Reorder the terms:

38 + 1 + 171 + 7x + -10x = 180

Combine like terms: 38 + 1 = 39

39 + 171 + 7x + -10x = 180

Combine like terms: 39 + 171 = 210

210 + 7x + -10x = 180

Combine like terms: 7x + -10x = -3x

210 + -3x = 180

Solving

210 + -3x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-210' to each side of the equation.

210 + -210 + -3x = 180 + -210

Combine like terms: 210 + -210 = 0

0 + -3x = 180 + -210

-3x = 180 + -210

Combine like terms: 180 + -210 = -30

-3x = -30

Divide each side by '-3'.

x = 10

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor in mathematics.

The numbers that can divide a number exactly are called factors. There is therefore no residual after division. The numbers you multiply together to obtain another number are called factors. A factor is therefore another number's divisor.

A parallelogram is a straightforward quadrilateral in Euclidean geometry that has two sets of parallel sides. In a particular kind of quadrilateral known as a parallelogram, both sets of opposite sides are parallel and equal. There are four different kinds of parallelograms, including three unique kinds. Parallelograms, squares, rectangles, and rhombuses are the four different shapes. Having two sets of parallel sides makes a quadrilateral a parallelogram. In a parallelogram, the opposing sides and angles are both the same length. On the same side of the horizontal line, the interior angles are additional angles as well. 360 degrees is the total number of interior angles.
