there is a 20% markup on a tv if the tv is $450 before the markup what is the cost after the markup

Answers

Answer 1

Hello!
If the markup is 20% you would multiply $450 by .20 to get $90. Then you add $90 to $450

Here's a simpler version...
$450x.20=$90
$450+$90=$540

The answer would equal $540.

Hope this helped!

Answer 2

The answer is 540 multiply 20 by 450 then divide by 100 and add 90

find the sum of all 3 digit whole numbers that arw divisible by 13 ?

Answers

We have an arithmetic sequence with

a0 = 1st 3-digit number divisible by 13
a0 = 104
d = 13 (why?)
last term is largest divisible by 13 = 988
how many terms? (988-104)/13 + 1 = 69

S = 69/2(104+988) = 37674

The sum of all 3-digit whole numbers that are divisible by 13 is [tex]$ \boxed{37674} $[/tex].

To find the sum of all 3-digit whole numbers that are divisible by 13, we can use the arithmetic series formula.

1. Identify the first and last 3-digit numbers divisible by 13:

- The smallest 3-digit number divisible by 13 is 104 (since [tex]$ 13 \times 8 = 104 $[/tex]).

- The largest 3-digit number divisible by 13 is 988 (since [tex]$ 13 \times 76 = 988 $[/tex]).

2. Calculate the number of terms in the series:

- Use the formula for the number of terms n in an arithmetic sequence:

[tex]\[ n = \frac{\text{last term} - \text{first term}}{\text{common difference}} + 1 \][/tex]

Here, the common difference d = 13:

[tex]\[ n = \frac{988 - 104}{13} + 1 = \frac{884}{13} + 1 = 68 + 1 = 69 \][/tex]

3. Find the sum of the arithmetic series:

- The sum [tex]$ S_n $[/tex] of the first n terms of an arithmetic series is given by:

[tex]\[ S_n = \frac{n}{2} \times (\text{first term} + \text{last term}) \][/tex]

Substitute the values:

[tex]\[ S_{69} = \frac{69}{2} \times (104 + 988) \][/tex]

Simplify the calculation:

[tex]\[ S_{69} = \frac{69}{2} \times 1092 = 34.5 \times 1092 = 37674 \][/tex]

Thus, the sum of all 3-digit whole numbers that are divisible by 13 is [tex]$ \boxed{37674} $[/tex].

what is the domian of the function y=In (-x+3/2)

Answers

Final answer:

The domain of the function y = ln (-x + 3/2) is all real numbers less than 3/2, represented in interval notation as (-∞, 3/2). This is because the argument of the logarithm must be positive, leading to an inequality that restricts x to be less than 3/2.

Explanation:

The domain of a function refers to the complete set of possible values of the independent variable. For the function y = ln (-x + 3/2), we must consider where the argument of the natural logarithm, -x + 3/2, is greater than zero. This is because the natural logarithm function is defined only for positive arguments.

To find the domain, set the argument of the logarithm function greater than zero: -x + 3/2 > 0. Solving this inequality, we find -x > -3/2, hence x < 3/2. This means that the domain of the function is all real numbers less than 3/2, which can be written in interval notation as (-∞, 3/2).

The domain of a function is the set of all possible input values. In the function y = ln(-x + 3/2), the natural logarithm function is defined only for positive numbers, so to find the domain, we need to identify the values of x that make the argument of the logarithm greater than zero.

Solve for the argument inside the logarithm to be greater than zero: -x + 3/2 > 0

Simplify the inequality to find the valid domain: x < 3/2

Therefore, the domain of the function y = ln(-x + 3/2) is x < 3/2.

the vertex of this parabola is at (3,5). When the y-value is 6, the x-value is -1. What is the coefficient of the squared term in the parabolas equation

Answers

now, assuming is a vertical parabola, so the squared variable is the "x", let's do some checking.

[tex]\bf \qquad \textit{parabola vertex form}\\\\ \begin{array}{llll} \boxed{y=a(x-{{ h}})^2+{{ k}}}\\\\ x=a(y-{{ k}})^2+{{ h}} \end{array} \qquad\qquad vertex\ ({{ h}},{{ k}})\\\\ -------------------------------\\\\ vertex \begin{cases} h=3\\ k=5 \end{cases}\implies y=a(x-3)^2+5 \\\\\\ \textit{we also know that } \begin{cases} y=6\\ x=-1 \end{cases}\implies 6=a(-1-3)^2+5 \\\\\\ 1=a(-4)^2\implies 1=16a\implies \cfrac{1}{16}=a[/tex]

The coefficient of the squared term in the parabola's equation, with a vertex at (3,5) and passing through the point (-1,6), is 1/16.

The student is asking about the coefficient of the squared term in the parabola's equation given that the vertex is at (3,5) and another point on the parabola is (-1,6). Since we know the vertex, we can write the vertex form of a parabolic equation as:

y = a(x - h)
^2 + k

Plugging the vertex into the equation, we get:

5 = a(3 - 3)
^2 + 5

This simplifies down to:

5 = a(0) + 5

So, we cannot determine 'a' from the vertex alone. However, we can use the other point to find 'a'. Plugging the coordinates (-1,6) into the vertex form, we get:

6 = a(-1 - 3)^2 + 5

6 = a(-4)^2 + 5

6 = 16a + 5

1 = 16a

a = 1/16

Therefore, the coefficient 'a' is 1/16.

Suppose the time to complete a 200-meter backstroke swim for female competitive swimmers is normally distributed with a mean μ = 141 seconds and a standard deviation σ = 7 seconds. suppose that to qualify for the nationals, a woman must complete the 200-meter backstroke in less than 128 seconds. what proportion of competitive female swimmers will qualify for the nationals? give your answer to four (4) decimal places.

Answers

Given that the time to complete a 200-meter backstroke swim for female competitive swimmers is normally distributed with a mean μ = 141 seconds and a standard deviation σ = 7 seconds.

The probability of a normally distributed data is given by:

[tex]P(X\ \textless \ x)=P\left(z\ \textless \ \frac{x-\bar{x}}{\sigma} \right)[/tex]

Thus, the probability that a woman completes the 200-meter backstroke in less than 128 seconds is given by:

[tex]P(X\ \textless \ 128)=P\left(z\ \textless \ \frac{128-141}{7} \right)=P(z\ \textless \ -1.857)=0.03165[/tex]

Therefore, the proportion of competitive female swimmers who will qualify for the nationals is 0.0317 to 4 decimal places.

A company borrowed $25,000 at 3.5% and was charged $2,625 in interest. How long was it before the company repaid the money?

Answers

3 years. Since no mention of compounding was made I will assume that it's 3.5% simple interest. So first, let's calculate what percent of the entire loan was interest. Just a simply matter of division. 2625 / 25000 = 0.105 = 10.5% Now lets' divide the percentage of the loan that was paid in interest by the interest rate. 10.5% / 3.5% = 3 So the company took 3 years to repay the loan.

Answer-

The company repaid the money in 3 years.

Solution-

A company borrowed $25,000 at 3.5% and was charged $2,625 in interest.

Considering the interest as simple interest,

[tex]\text{interset}=\dfrac{\text{Principal}\cdot \text{Rate of interest}\cdot \text{Time period}}{100}[/tex]

Here,

Interest = $2625

Principal = $25000

Rate of interest = 3.5% annually

Putting the values,

[tex]\Rightarrow 2625=\dfrac{25000\times 3.5\times t}{100}[/tex]

[tex]\Rightarrow t=\dfrac{2625\times 100}{25000\times 3.5}[/tex]

[tex]\Rightarrow t=3\ years[/tex]

Therefore, the company repaid the money in 3 years.

The time required for the principal amount to double is 13 years 10 months and 10 days approx.

What is compound interest?

Compound interest simply refers to the fact that an investment, loan, or bank account's interest accrues exponentially over time as opposed to linearly over time. The term "compound" is crucial here.

CI Formula. C.I. = Principal (1 + Rate)^time − Principal.

Given, A sum of $5000 is invested at an interest rate of 5% per year.

hence, principle = 5000

Amount = 10000

rate = 5%

let's assume the time is x

Let's solve for time

A(t)= 10000 = 5000* e⁵ˣ/¹⁰⁰

2 = (e)^x/20

taking logs on both sides

ln 2 = x / 20

x = 20 ln2

time required = 20 ln2 = 20 * 0.69 = 13.86

Therefore, To make the amount double at the interest rate of 5% we need time approx 13 years 10 months, and 10 days.

a right triangle has one angle that measures 23 degress.The adjacent leg measures 27.6 cm and the hypotenuse measures 30 cm.What is the approximate area of the triangle?Round to the nearest tenth.Area of a triangle =1/2bh

Answers

Sent a pic of the solution (s).

Answer:

Area of the triangle will be 162.3 cm²

Step-by-step explanation:

From the figure attached,

In the triangle ABC angle ACB = 23°, side BC = 27.6 cm and hypotenuse AC = 30 cm

Now we have to calculate the area of the given right angle triangle.

Since area of a right angle triangle is represented by

Area = [tex]\frac{1}{2}\times b\times h[/tex]

Where b = adjacent side

h = opposite side

To calculate the opposite side of the triangle we will apply Pythagoras theorem in the ΔABC.

AC² = AB² + BC²

AB² = AC² - BC²

AB² = (30)² - (27.6)²

= 900 - 761.76

= 138.24

AB = √138.24

= 11.76

Area of the triangle = [tex]\frac{1}{2}(AB)(BC)[/tex]

= [tex]\frac{1}{2}(11.76)(27.6)[/tex]

= 162.28 cm² ≈ 162.3 cm²
