Answer:

57.50

Step-by-step explanation:

simply divide 345/6 which equals 57.5 which is 57.50

Answer:

price before fee was applied is $46.25

Step-by-step explanation:

$345/6= $57.5

divide total cost by number of tickets bought

$57.5-$11.25= $46.25

subtract the fee applied

Answer:

Her investment will grow over the years due to the 2 percent interest. Inflation will impact the value of her investment

For the given data. the simple interest will be $100.His investment will grow over the years. Because of the simple interest.

It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.

It is given that, Pardis recently deposited $5,000 in a savings account that pays a return of 2 percent per year.

Principal = $5,000

Rate= 2%

Time= 1 year

SI = (P×R×T)/100

SI = (5000×2×1)/100

SI=100

Thus, for the given data. the simple interest will be $100.His investment will grow over the years. Because of the simple interest.

Answer:

2 units

Step-by-step explanation:

Answer:

the correct answer is that mary sold 18 adult tickets and 32 student tickets

if she sold 18 adult tickets it would be 90 dollars, and if she sold 32 student tickets she would get 64 from that, if we add the amount of people that bought tickets and how much she got it would work out

with 18 adults+32 students being exactly 50

and 90+64 being 154.

I tried different solutions, I did 18 adults and 32 Students, since there are 50 tickets sold, this is the correct answer since if we do this the amount she makes from the adults will be 90 and she will make 64 from the students this will add up to $154

Answer:

c ≈ 9.1 m

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

c² = 4.1² + 8.1² = 16.81 + 65.61 = 82.42 ( take square root of both sides )

c = [tex]\sqrt{82.42 }[/tex] ≈ 9.1 m ( to the nearest tenth )

Answer:

-3

Step-by-step explanation:

The value of f(-3) can be found at looking at the x-value of -3, then drawing a vertical line. If you look at the point where the vertical line hits th graph, you get the point (-3,-3)

The y-value is what we are looking for, which is -3.

Answer:

EG = 2 units

Step-by-step explanation:

Given that line q bisects EG at T , then

ET = TG  ( substitute values )

[tex]\frac{1}{3}[/tex] x = x - 2 ( multiply through by 3 to clear the fraction )

x = 3x - 6 ( subtract x from both sides )

0 = 2x - 6 ( add 6 to both sides )

6 = 2x ( divide both sides by 2 )

3 = x

Then

ET = [tex]\frac{1}{3}[/tex] x = [tex]\frac{1}{3}[/tex] × 3 = 1

TG = x - 2 = 3 - 2 = 1

Thus

EG = ET + TG = 1 + 1 = 2 units

EG = [tex] \frac{4x}{3} - 2[/tex]

Step-by-step explanation:

( First check the attached image for diagram )

[tex]EG=ET+TG[/tex]

Substituting the given values,

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

Opening the brackets and multiplying,

[tex]EG = \frac{1 \times x}{3} + x - 2 [/tex]

[tex] = > EG = \frac{x}{3} + x - 2[/tex]

Finding LCM,

[tex] = > EG = ( \frac{x}{3} + \frac{x \times 3}{1 \times 3} ) - 2[/tex]

[tex] = > EG = ( \frac{x}{3} + \frac{3x}{3}) - 2[/tex]

Combining them,

[tex]EG =( \frac{x + 3x}{3}) - 2[/tex]

[tex]EG = \frac{4x}{3} - 2[/tex]

Note:- T is midpoint of EG

because ET = TG

Answer:

518000 if it increases 8% per year

Step-by-step explanation:

8 times 5, because there are 5 years, is 40%

we take 40% out of 370000 and we get 148000 then we add 370000 and 148000 together and we get 518000

Answer:

1/3

Step-by-step explanation:

[tex]\frac{6}{9}*\frac{1}{2}[/tex]

[tex]\frac{6*1}{9*2}[/tex]

[tex]=\frac{6}{18}[/tex]

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(6,18) = 6

[tex]\frac{6/6}{18/6}=\frac{1}{3}[/tex]

Therefore:

[tex]\frac{6}{9}*\frac{1}{2}=\frac{1}{3}[/tex]

Answer:

1,995 would round to 2,000

Step-by-step explanation:

1,995 is 5 away from 2,000 so if you were rounding to the nearest hundred 2,000 would be it

same as before, we look at the denominators, hmmm do a quick prime factoring.

3 = 3 * 1

9 = 3 * 3 * 1

since 9 already contains 3 and 1, we can us that

[tex]\cfrac{\underline{2}}{3}~~ - ~~\cfrac{1}{9}\implies \cfrac{(2)\underline{2}~~ - ~~(1)1}{\underset{\textit{using this LCD}}{9}}\implies \cfrac{4-1}{9}\implies \cfrac{\stackrel{1}{~~\begin{matrix} 3 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}}{\underset{3}{~~\begin{matrix} 9 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}}\implies \cfrac{1}{3}[/tex]

Okay so, to solve these problems what you're gonna want to do is substitute the given x and y values into the equation.

For example, number 7.

11(d-c) + 3(c+d), when c=6, d=9

if d=9, you will substitute the d in the problem to 9.

11(9-c) + 3(c+9)

if c=6 you will substitute c for 6.

11(9-6) + 3(6+9)

You can solve now that you have a simpler problem to work with.

11(9-6) + 3(6+9) first...

11(9-6)  11*9=99   11*-6=-66, so, 11(9-6)= 99-66= 33.

3(6+9) 3*6=18 3*9=27 18+27=45

33+45=78

Your answer for number 7 is 78.

Hope this helps, just do the same for the other problems like this one.

Answer:

50,000

Step-by-step explanation:

1st car had $1,750 tax

2nd car has $3,500 tax

1750(2) = 3500

so your tax doubled so the price must be doubled.

The car is $50,000

Algebraically using direct variation:

t = kp    where t=tax, p = purchase price, 

             and k is constant of variation

1750 = 25000k

k = 1750/25000

k = 0.07

Your equation is:  t = 0.07p

3500 = 0.07p

p = 3500/0.07

p = $50,000

a) c = 20
b) b = 16.5
c) a = -3
d) c = 2.5
e) a = 0.8

There are not enough information on these sequences, so I will just do them base on the difference of the numbers.
