Answer:

[tex]\displaystyle \frac{3^5}{3^{-6}}=3^{11}[/tex]

Step-by-step explanation:

Properties of Exponents

They can be used to simplify expressions of the form

[tex]b^x\cdot b^y=b^{x+y}[/tex]

[tex]\displaystyle \frac{b^x}{b^y}=b^{x-y}[/tex]

The last property will be used to simplify:

[tex]\displaystyle \frac{3^5}{3^{-6}}=3^{5-(-6)}=3^{5+6}=3^{11}[/tex]

[tex]\mathbf{\displaystyle \frac{3^5}{3^{-6}}=3^{11}}[/tex]

The amount she will have left after writing a check for $23.99 is $13.26. The correct answer would be an option (C).

Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

Tricia has $37.25 in her account, if she writes a check for $23.99, to find the amount left after that we need to subtract the check amount from her initial amount.

⇒ initial amount - check amount

⇒ $37.25 - $23.99

Apply the subtraction operations, and we get

⇒ $13.26

Therefore, the amount she will have left after writing a check for $23.99 is $13.26.

Answer:

509

Step-by-step explanation:

formula

L = a + (n - 1)*d

Givens

n = 57

a = 5

d = 9

Solution

t = 5 + (57 - 1)*9

t = 5 + 56*9

t = 5 + 504

t = 509

t = 556

Answer:

50 packs.

Step-by-step explanation:

Given the following data;

Length = 28 feet

Width = 25 feet

Pack of seeds = 14 ft²

Since Kevin's backyard is a rectangle, we would find its area.

Area of rectangle = length * width

Substituting into the equation, we have;

Area of rectangle = 28 * 25

Area of rectangle = 700 ft²

Now to find the amount of pack of seeds required to cover the backyard.

Amount of pack of seeds = 700/14

Amount of pack of seeds = 50 packs.

Answer:

100+50²=2600

Step-by-step explanation:

because 50x2=100 and 50² is 2500. Add those and you get 2600.

Step-by-step explanation:

Answer:

[tex]r=-3[/tex]

Step-by-step explanation:

We have the equation:

[tex]\displaystyle \frac{1}{3}r+1=-\frac{2}{3}r-2[/tex]

And we would like to solve for r.

First, we can multiply both sides by the denominator 3. This will remove the fractions. So:

[tex]\displaystyle 3(\frac{1}{3}r+1)=3(-\frac{2}{3}r-2)[/tex]

Distribute:

[tex]\displaystyle r+3=-2r-6[/tex]

Now, we can add 2r to both sides:

[tex]3r+3=-6[/tex]

And we can also subtract 3 from both sides:

[tex]3r=-9[/tex]

Finally, we can divide both sides by 3 to get:

[tex]r=-3[/tex]

P(X>5) = 0.857

Step-by-step explanation:

Let X [tex]\sim[/tex] uniform(3.17)

[tex]f(x) = \dfrac{1}{17-3} ; \ \ \ 3 \le x \le 17[/tex]

The required probability that it will take Isabella more than 5 minutes to wait for the bus can be computed as:

[tex]P(X > 5) = \int ^{17}_{5} f(x) \ dx[/tex]

[tex]P(X > 5) = \int ^{17}_{5} \dfrac{1}{17-3} \ dx[/tex]

[tex]P(X > 5) =\dfrac{1}{14} \Big [x \Big ] ^{17}_{5}[/tex]

[tex]P(X > 5) =\dfrac{1}{14} [17-5][/tex]

[tex]P(X > 5) =\dfrac{12}{14}[/tex]

P(X>5) = 0.857

Answer:

Kristen should walk 12 miles to catch up with Paul

Step-by-step explanation:

Paul = 2hrs earlier

      = walks at 3 miles per hour

      = 3miles x 2 hrs = 6 miles

covers 6 miles at the time Kristen starts

Kristen = 4 miles per hour

Paul has a lead of 6 miles.

if Kristen walks another hour of 4 miles she would have covered 8 miles and Paul would have covered 9 miles and if  Kristen were to cover one more hour,

Kristen would be at 12 and so would Paul.

Kristen should walk 12 miles to catch up with Paul

Answer:

(4n − 1)(n − 4)

Explanation:

Factor 4n² − 17n + 4

4n² − 17n + 4

= (4n − 1)(n − 4)

Answer:

(4n − 1)(n − 4)

The factors of the expression [tex]4n^2-17n+4[/tex] are

Mathematically, an expression is a combination of numbers, variables, operations, and functions that are combined according to specific rules to represent a mathematical computation or relationship. It can be thought of as a mathematical phrase or formula.

To factorize the quadratic expression [tex]4n^2 - 17n + 4[/tex], we need to find two binomial factors that, when multiplied, result in the given expression.

The factored form will have the following structure:

(An + B)(Cn + D)

To find the values of A, B, C, and D, we can use various methods such as factoring by grouping, quadratic formula, or completing the square. In this case, we will use the factoring by grouping method.

Step 1: Multiply the coefficient of the leading term (4) by the constant term (4). The result is 16.

Step 2: We need to find two numbers that multiply to give 16 and add up to the coefficient of the linear term (-17). After considering the possible pairs of numbers, we find that -16 and -1 meet these criteria.

Step 3: Rewrite the middle term (-17n) using -16n - n:

= [tex]4n^2 - 16n - n + 4[/tex]

Step 4: Group the terms and factors by grouping:

= [tex](4n^2 - 16n) - (n - 4)[/tex]

= 4n(n - 4) - 1(n - 4)

Step 5: Factor out the common binomial factor:

(n - 4)(4n - 1)

Therefore, the factored form of the quadratic expression [tex]4n^2 - 17n + 4[/tex] is (n - 4)(4n - 1).
