A store regularly sells a Nintendo Switch Lite for $200. They are currently on sale for 30% off and in your state the sales tax is 8%. What would be the final cost for the consumer (including tax) if they buy the Nintendo Switch Lite?
Answer:
$151.20
Step-by-step explanation:
The sale price of the Nintendo Switch Lite is 30% off its regular price of $200, which means the discount is:
Discount = 30% x $200 = $60
The sale price of the Nintendo Switch Lite after the discount is:
Sale price = $200 - $60 = $140
The sales tax in the state is 8%, so the tax amount on the sale price is:
Tax amount = 8% x $140 = $11.20
Therefore, the final cost for the consumer, including tax, would be:
Final cost = Sale price + Tax amount = $140 + $11.20 = $151.20
Hence, the final cost for the consumer, including tax, would be $151.20 if they buy the Nintendo Switch Lite.

Answer:
(D) 85 cm².
Step-by-step explanation:
To find the area of a triangle, we can use the formula:
Area = (1/2) x base x height
In this case, we are given the lengths of three sides of the triangle, but we need to find the height. One way to do this is to use Heron's formula to calculate the area directly, but another approach is to use the Pythagorean theorem to find the height.
We can see that the side lengths of the triangle are 17 cm, 10 cm, and 9 cm. Let's assume that the side of length 17 cm is the base of the triangle. Then, we can draw an altitude from the vertex opposite the base to the base, creating two right triangles. The height of the triangle is the length of this altitude.
Using the Pythagorean theorem in one of the right triangles, we can solve for the height as follows:
(Height)^2 = (10 cm)^2 - (4.5 cm)^2
Height = sqrt[(10 cm)^2 - (4.5 cm)^2]
Height = sqrt[100 cm^2 - 20.25 cm^2]
Height = sqrt(79.75) cm
Height ≈ 8.93 cm
Now that we have the base and height of the triangle, we can use the formula for the area of a triangle:
Area = (1/2) x base x height
Area = (1/2) x 17 cm x 8.93 cm
Area ≈ 76.025 cm²
Therefore, the area of the triangle is approximately 76.025 cm². None of the answer choices match this result exactly, but the closest option is (D) 85 cm².
Answer:
A
Step-by-step explanation:
The formula of a triangle is Base x Height ÷ 2 = Area
10 x 9 = 90 sq cm
90 ÷ 2 = 45
So answer is A
the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

My mom doesn't understand this question:
\(7\frac{1}{5} - 5\frac{1}{4}\)
Please solve this equation step by step and explain, preferably with multiple methods. I tried explaining it to her but she still doesn't get it.
Thanks!
The solution of the given expression is-
\(7\frac{1}{5} -5\frac{1}{4} = 1\frac{19}{20}\)
We must first transform mixed fractions into improper fractions before we can subtract them.
Let's transform \(7\frac{1}{5}\) it into an improper fraction :
\(7 \frac{1}{5} = \frac{(7 * 5 + 1)}{5} = \frac{36}{5}\)
Let's change \(5\frac{1}{4}\) into an improper fraction now:
\(5\frac{1}{4} = \frac{(5 * 4 + 1)}{4} = \frac{21}{4}\)
We can now subtract the fractions:
To subtract fractions, we need to find a common denominator. The least common multiple or the LCM of 5 and 4 is 20.
Converting the fractions to have a common denominator of 20:
(36/5) * (4/4) = 144/20
(21/4) * (5/5) = 105/20
So the subtraction will be as follows:
\(\frac{36}{5} -\frac{21}{4} =\frac{(36*4)+(21*5)}{4*5} =\frac{144-105}{20}=\frac{39}{20}\)
Therefore, \(7\frac{1}{5} -5\frac{1}{4}\) is equal to \(\frac{39}{20}\) or, \(1\frac{19}{20}\) .
The solution of the given expression is-
\(7\frac{1}{5} -5\frac{1}{4} = 1\frac{19}{20}\)

Step-by-step explanation:
Consider the infinite geometric series infinity sigma n=1 -4(2/3)^n-1. In this, the lower limit of the summation notion is "n=1". PLEASE show your work I dont understand
1)write the first four terms of the series 2) does the series diverge or coverge 3) if the series has a sum find the sum
Answer:
To find the first four terms of the series, we can substitute the values of n from 1 to 4 in the given formula and simplify:
n=1: -4(2/3)^0 = -4(1) = -4
n=2: -4(2/3)^1 = -4(2/3) = -8/3
n=3: -4(2/3)^2 = -4(4/9) = -16/9
n=4: -4(2/3)^3 = -4(8/27) = -32/27
So the first four terms of the series are -4, -8/3, -16/9, -32/27.
To determine if the series converges or diverges, we need to find the common ratio r, which is the ratio of any term to its preceding term:
r = (-4(2/3)^n) / (-4(2/3)^(n-1)) = 2/3
Since the absolute value of the common ratio is less than 1, the series converges.
To find the sum of the series, we can use the formula for the sum of an infinite geometric series:
S = a / (1 - r)
where a is the first term and r is the common ratio. Substituting the values we found:
S = -4 / (1 - 2/3) = -4 / (1/3) = -12
So the sum of the infinite geometric series is -12.
Answer:
a) The first four terms of the series are:
-4, -8/3, -16/9, -32/27
b) The series converges.
c) The sum of the infinite geometric series is -12.
Step-by-step explanation:
Given infinite geometric series:
\(\displaystyle \sum^{\infty}_{n=1} -4 \left(\dfrac{2}{3}\right)^{n-1}\)
Therefore, the formula for the nth term of the sequence is:
\(a_n=-4 \left(\dfrac{2}{3}\right)^{n-1}\)
where:
-4 is the first term, a.2/3 is the common ratio, r.Calculate the first four terms of the series by substituting the n-values 1 through 4 into the nth term formula.
\(a_1 = -4 \left(\dfrac{2}{3}\right)^{1-1} = -4 \left(\dfrac{2}{3}\right)^{0}=-4\)
\(a_2 = -4 \left(\dfrac{2}{3}\right)^{2-1}= -4 \left(\dfrac{2}{3}\right)^{1}=-\dfrac{8}{3}\)
\(a_3 = -4 \left(\dfrac{2}{3}\right)^{3-1}= -4 \left(\dfrac{2}{3}\right)^{2}=-4 \left(\dfrac{4}{9}\right)=-\dfrac{16}{9}\)
\(a_4 = -4 \left(\dfrac{2}{3}\right)^{4-1}= -4 \left(\dfrac{2}{3}\right)^{3}= -4 \left(\dfrac{8}{27}\right)=-\dfrac{32}{27}\)
A geometric series converges if the absolute value of its common ratio is less than 1. As r = 2/3 and |2/3| < 1, the series converges.
Use the infinite geometric series sum formula to find sum of the infinite series.
\(\boxed{\begin{minipage}{5.5 cm}\underline{Sum of an infinite geometric series}\\\\$S_{\infty}=\dfrac{a}{1-r}$,\;\;for\;$|r| < 1$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\ \phantom{ww}$\bullet$ $r$ is the common ratio.\\\end{minipage}}\)
Substitute a = -4 and r = 2/3 into the formula to find the sum of the infinite series:
\(\begin{aligned}\implies S_{\infty}&=\dfrac{-4}{1-\frac{2}{3}}\\\\ &=\dfrac{-4}{\frac{1}{3}}\\\\&=-4 \cdot \dfrac{3}{1}\\\\&=-\dfrac{12}{1}\\\\&=-12\end{aligned}\)
Therefore, the sum of the given infinite geometric series is -12.
