Samantha buys $128 worth of goods at a 25% discount. If the sales tax rate is 6.4%, what is the total amount she will pay?
Answer: 102.144
Step-by-step explanation:
128 times 0.25 = 32
128 - 32 = 96
96 times 1.064 = 102.144

Step-by-step explanation:
Planets Mars, Neptune, Earth, Saturn
Diameter (km) 6770 49244 12742 116460
The least diameter is of mars, then is of the earth, then Neptune and the greatest in the list is of Saturn.
The list of least to greatest would be
Mars, Earth, Neptune, Saturn
The mars is farther to the sun as compared to the earth. As the planet moves away from the Sun it's orbit becomes bigger and bigger. Neptune is the eigth planet and saturn is the sixth planet.
Lisa loaned John $5000 at an interest rate of 6%. He repaid her $5750 to cover the principal and interest. How long did he borrow the money?
Answer:
time in years = 2.5 years
Step-by-step explanation:
time = interest / (principal amount x rate)
time = 750 / 5000 x 0.06
time = 750 / 300
time = 2.5 years

Raj and his friends went to the movies today and ate 875 pieces of popcorn, or 125% more than they ate when they went to the movies last week.
A tape diagram. StartFraction part Over whole EndFraction = StartFraction 125 Over 100 EndFraction = StartFraction 875 Over question mark EndFraction.
Which steps can be used to find how much popcorn Raj and his friends ate at the movies last week?
Check all that apply.
125 + 750 = 875
125 × 7 = 875
100 × 7 = 700 pieces of popcorn
100 + 750 = 850 pieces of popcorn
125 + 875 = 1000 pieces of popcorn

What are the key features of function f? f(x)=log x
Answer:
(1,0)-------Increases------X=0-----Decreases to negative infinity
Step-by-step explanation:
Value of function f(x) = logx at axis (1,0) is zero.
What is graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
The graph of the logarithmic function y=logx is shown.
The domain of function f(x) = logx is the set of all positive real numbers.
1. f(x)=logx domain of the logirthimic function is (0, ∞).
2. The range is the set of all real numbers.
3. The function is continuous and one-to-one.
4. The y-axis is the asymptote of the graph.
5. The graph intersects the x-axis at (1,0). That is, the x-intercept is 1.
Value of function f(x) = logx at axis (1,0)
⇒ f(x) = 0
Thus, value of function f(x) = logx at axis (1,0) is zero.

O July 1, 1979
O June 17, 1997
O June 1, 1997
Answer:
June 7th, 1979
Step-by-step explanation:
1979 comes before 1997, so that eliminates those. Then June comes before July. So June 7th, 1979.
June 7, 1979, is the earliest date. Option A is correct.
How to represent the date?The recommended format for writing dates is YYYY-MM-DD, which stands for year, month, and day.
Since 1979 came before 1997, those are disregarded. June, therefore, precedes July. So, it's June 7, 1979.
The earliest date is June 7, 1979.
Hence option A is correct.

Jackson's rectangular bedroom has an area of 80 square feet. The area of his bedroom is 10 times that of his rectangular closet. If the closet is 2 feet wide, what is its length? BE SURE TO ADD A LABEL TO YOUR ANSWER.
Answer:
Length of the rectangular closet = 4 feet
Step-by-step explanation:
Area of his bedroom = 80 square feet.
The area of his bedroom = 10 times that of his rectangular closet.
Let x = area of his rectangular closet.
80 = 10 * x
80 = 10x
x = 80/10
= 8
x = 8 square feet
If the closet is 2 feet wide, what is its length?
Area of the rectangular closet = length × width
Let y = Length of the rectangular closet
8 Square feet = y feet × 2 feet
8 = 2y
y = 8/2
= 4
y = 4 feet
Length of the rectangular closet = 4 feet

help asap! ill give the best to person who explains it clearly
Answer:
The answer is D.
Step-by-step explanation:
First, you have to find the area of circle using the formula :
A = π × r²
A = π × 3²
A = 9π
Given that PHU is an equilateral triangle so all sides have a degree of 60°. Next, you have to find the area of minor sector of P and U by using the formula :
A = (θ/360) × π × r²
A = (60/360) × π × 3²
A = 1.5π
Lastly, you have to subtract the area of sector from the area of circle in order to find the area of shaded region :
A = (9π × 2) - (1.5π × 2)
A = 18π - 3π
A = 15π

What is the polar form of Negative 2 StartRoot 3 EndRoot minus 6 i?
Answer:
4√3 [cos (2π/3) + isin(2π/3)]
Step-by-step explanation:
We are to write out the polar form of:
-2√3 - 6i
In Mathematics:
The polar form of a given complex number a + bi is given as r[cos(θ)+isin(θ)],
where r =√a²+b²and
θ = arc tan (b/a) when a is > 0
or arc tan (b/a) + π or arc tan (b/a) + 180 when a is < 0
From the above question:
-2√3 - 6i
We have that
a = −2√3 and b = −6
Hence:
r =√a²+b²
r = √(-2√3)² + (-6)²
r = √(4 × 3) + 36
r = √12 + 36
r = √48
r = √16 × 3
r = 4√3
a is < 0
Hence,
θ = arc tan (b/a) + π
θ = arc tan (-6/-2√3) + π
θ = 2π/3
Substituting 4√3 for r and 2π/3 for θ in:
r[cos(θ)+isin(θ)]
-2√3 - 6i = 4√3 [cos (2π/3) + isin(2π/3)]

Kaya had a string 6 1/8 inches long. She cut off a piece 2 3/4 inches long. How long is the remaining piece of string? Show your work. Write your answer as a mixed number.
Answer: 3 3/8
Step-by-step explanation:
We know that for example 2/4=4/8 so it is multiplied by 2. In this problem the fractions are 2 2/4 and 6 1/8. We are subtracting so you would first multiply the fraction that’s going to subtracted from the other fraction 2 3/4= 2 6/8. Now that we have our fractions we can subtract 6 1/8-2 6/8 this would leave us with 3.375 which is equal to 3 3/8.
Answer:
3 3/8

If you take away 2 3/4 from 6 1/8 it would equal 3 3/8 how you get that answer I'm not really sure but I used google 0_0 but there you go I hope it helped-
