Answer:

$347.45

Step-by-step explanation:

total = tickets + parking + t shirt + meal

tickets = 250 + 6% tax

6% tax is of 250, so this is equal to

250 + 6% of 250

6% = 0.06 because we divide by 100 to convert to a decimal from a percentage

thus, tickets = 250 + 0.06 of 250 = 250 * 1 + 0.06 * 250 + 1.06 * 250 = 265

parking = 20

use a similar strategy from the tickets and apply that to the t shirt

t shirt = 35 + 7 % tax = 35 + 0.07 * 35 = 1.07 * 35 = 37.45

meal = 25

total = 265 + 20 + 37.45 + 25 = $347.45

Answer:

$30.00

Step-by-step explanation:

The original price of the sweater is $75.00.  The new sale price is the original price of  100% less  60% of the original price.  That means the sales price is 40% of the original price.

You can do this 2 ways:

1.  $75 x 60% or .60 = $45

  $75-45 = $30

or

2.  $75 x 40% or .40 = $30

Answer:

Question 1

The function [tex]f(x) = x + 6[/tex] is one-to-one, so it does have an inverse.

The inverse of +6 is -6, so [tex]f^{-1}(x)=x-6[/tex]

Therefore, g(x) is the inverse of f(x).

Question 2

The function [tex]f(x) = -3x -9[/tex] is one-to-one, so it does have an inverse.

To find the inverse, replace f(x) with y:

[tex]\implies y = -3x -9[/tex]

Rearrange the equation to make x the subject:

[tex]\implies y+9= -3x[/tex]

[tex]\implies x=-\dfrac13(y+9)[/tex]

[tex]\implies x=-\dfrac13y-3[/tex]

Replace x with [tex]f^{-1}(x)[/tex] and y with x:

[tex]\implies f^{-1}(x)=-\dfrac13x-3[/tex]

Therefore, g(x) is the inverse of f(x).

Answer:

Option A, [tex]L = 243\ ft[/tex]

Step-by-step explanation:

Step 1:  Create an equation

[tex]Length = 4 * Width[/tex]

[tex]Area = (4 * W) * W[/tex]

[tex]Area = 4 W^2[/tex]

Step 2:  Solve for W

[tex]14800\ ft^2 = 4 W^2[/tex]

[tex]\frac{14800\ ft^2}{4} = W^2[/tex]

[tex]3700\ ft^2 = W^2[/tex]

[tex]\sqrt{3700\ ft^2} = \sqrt{W^2}[/tex]

[tex]61\ ft = W[/tex]

Step 3:  Solve for L

[tex]Length = 4 * Width[/tex]

[tex]L = 4 * 61\ ft[/tex]

[tex]L = 243\ ft[/tex]

Answer:  Option A, [tex]L = 243\ ft[/tex]

Answer:

  (a) correct

  (b) -48 ft/s

  (c) -32 ft/s; -64 ft/s

  (d) 9.257 s

  (e) -296.216 ft/s

Step-by-step explanation:

You are given an equation of motion and asked to find velocity and time at different points in the motion. This requires you differentiate the position function to find velocity, and that you solve the position function to find the time at a particular position.

__

The coin is "dropped", so is presumed to have no initial velocity. The initial height is given as 1371 feet. Putting these values into the given equation, you have ...

  s(t) = -16t² +1371

The velocity is the derivative of this function:

  v(t) = -32t

__

The average velocity on an interval is the change in position divided by the change in time:

  (s(2) -s(1))/(2 -1) = ((-16·2² +1371) -(-16·1² +1371))/1 = -16(4 -1) = -48 . . . ft/s

(Note: the average velocity for a quadratic position function is the velocity at the midpoint of the interval: v(1.5) = -32(1.5) = -48 . . . ft/s.)

__

Use the velocity function you found in part (a) to determine the instantaneous velocity at the given times:

  v(1) = -32(1) = -32 . . . ft/s

  v(2) = -32(2) = -64 . . . ft/s

__

The coin will reach the ground when s(t) = 0. Solving for t, we find ...

  s(t) = 0

  -16t² +1371 = 0

  1371 = 16t²

  t = √(1371/16) = (√1371)/4 ≈ 9.257 . . . . seconds

__

The velocity at impact will be ...

  v(√1371/4) = -32(√1371/4) = -8√1371 ≈ -296.216 . . . ft/s

Answer:

A) R24.10
B) R25.90

((ASSUMING THERES NO TAXES WITH THE PAYMENT))

Step-by-step explanation:
A)

first add up the costs of each item to get the ttal cost with addition as follows...

9.50 + 0.50 + 2.75 + 11.35 ((Adding like terms by adding 0.50 to 9.50 equaling 10.00))

10.00 + 2.75 + 11.35 ((adding the more simple options togeter since .75 is a more common fraction at 3/4))

12.75 + 11.35 ((finnishing off the system by adding the last two numbers together equaling to 24.10))

therefore Thabo spent a total of 24.10

B)
to find out the change, all we need to do is subtract the total cost from the total amount Thabo used to pay as shown below

50.00 - 24.10

in conclusion, Thabo would have R25.90 in change from the transaction ((assuming theres no tax))

Answer:

Option D, 174 ft

Step-by-step explanation:

Step 1:  Create an equation

[tex]B = 6H[/tex]

[tex]Area = (6H) * H[/tex]

Step 2:  Divide both sides by 6

[tex]5040\ ft^2 = 6H^2[/tex]

[tex]\frac{5040\ ft^2}{6} = \frac{6H^2}{6}[/tex]

[tex]840\ ft^2 = H^2[/tex]

Step 3:  Square root both sides

[tex]\sqrt{840\ ft^2} = \sqrt{H^2}[/tex]

[tex]29\ ft = H[/tex]

Step 4:  Find the base

[tex]A = B * H[/tex]

[tex]5040\ ft^2 = B * 29\ ft[/tex]

[tex]\frac{5040\ ft^2}{29\ ft} = \frac{B*29\ ft}{29\ ft}[/tex]

[tex]174\ ft = B[/tex]

Answer:  Option D, 174 ft

Answer:

D

Step-by-step explanation:

You can combine like terms meaning (8x+14)+ (9x-5) is 17x+9

Hi!

Given:

[tex](8x+14) + (9x-5)[/tex]

As we are adding the two groups, we can safely take them out of parentheses, as none of the signs will change:

[tex]8x+14+9x-5[/tex]

Now, we can rearrange them to make it easier, placing like terms next to each other:

[tex]8x+9x+14-5[/tex]

Now, add like terms:

[tex]17x+9[/tex]

Therefore, your answer is D.

Answer:

6.63 ft

Step-by-step explanation:

10² + h² = 12²

h² = 12² - 10²

h² = 144 - 100

h = √(44)

h = 2√11

6.63325 ft

The equation that results if Kiran squares both sides as his first step is gotten as; x + 2 - 10√(x + 2) + 25 = 121

We want to simplify the expression;

[√(x + 2)] - 5 = 11

Squaring both sides is;

([√(x + 2)] - 5) * ([√(x + 2)] - 5) = 11 * 11

⇒ x + 2 - 10√(x + 2) + 25 = 121

Thus, the correct answer is;

x + 2 - 10√(x + 2) + 25 = 121

Answer:

SMALLEST TO GREATEST

102 mm --> 125 mm --> 10.4 cm --> 0.12 m.

Explanation:

Millimeters (mm) is smaller than centimeters (cm). Centimeters are smaller than meters (m).

And, since both 125 mm and 102 mm has the same units of measurement, 125>102.

So, 102 goes in front of 125.

And then the rest of the order is completed by comparing the units of measurement.

Answer:

t = 14 years

Step-by-step explanation:

r = R/100

r = 9/100

r = 0.09 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(9,589.78/2,733.00) / ( 12 × [ln(1 + 0.09/12)] )

t = ln(9,589.78/2,733.00) / ( 12 × [ln(1 + 0.0075)] )

t = 14 years

Summary:

The time required to get a total amount of $9,589.78 with compoundeded interest on a principal of $2,733.00 at an interest rate of 9% per year and compounded 12 times per year is 14 years.
