Darius lives in Ohio and pays 5.5% in sales tax. If he just bought a sweatshirt that cost $24, what was the total amount he paid

ollegr [7]

In this question, we are required to find the total amount he paid to buy the shirt.

It is given that sales tax is 5.5 % over the amount paid.

The cost price of the shirt = $ 24.

The total amount will be = Cost price + 5.5 % of Cost price

Total amount paid = $ 24 × 1.055 (i.e. 100 % + 5.5 %)

Total amount = $ 24 + (5.5 % × $ 24)

Total amount paid = $ 24 + $ 1.32 = $ 25.32

−9x+4y=6 9x+5y=−33

blsea [12.9K]

Answer:

{x,y} = {-2,-3}

Step-by-step explanation:

System of Linear Equations entered :

[1] -9x + 4y = 6

[2] 9x + 5y = -33

Graphic Representation of the Equations :

4y - 9x = 6 5y + 9x = -33

Solve by Substitution :

// Solve equation [2] for the variable y

[2] 5y = -9x - 33

[2] y = -9x/5 - 33/5

// Plug this in for variable y in equation [1]

[1] -9x + 4•(-9x/5-33/5) = 6

[1] -81x/5 = 162/5

[1] -81x = 162

// Solve equation [1] for the variable x

[1] 81x = - 162

[1] x = - 2

// By now we know this much :

x = -2

y = -9x/5-33/5

// Use the x value to solve for y

y = -(9/5)(-2)-33/5 = -3

two mountain bikers leave from the same parking lot and head in opposite directions on two different trails. the first rider goe

sveta [45]

Applying the required rule or theorem, it can be concluded that the second biker is farther from the parking lot. The distance of the bikers to the parking lot are:

i. First biker = 17.0 km

ii. Second biker = 20.22 km

The path of travel of both bikers would form a triangle. Applying the Pythagoras theorem to the path of the first biker would give his distance from the starting point. While applying the cosine rule to the path of second rider would gives his distance to the starting point.

Thus,

a. To determine the distance of the first biker from the parking lot.

Let the required distance be represented by x. Applying the Pythagoras theorem, we have:

$hyp^{2}$ = $adj 1^{2}$ + $adj 2^{2}$
