Answer:Jake's total cost is $22.05

Step-by-step explanation:

The initial price of the sweater is $30. The store is having a sell that will reduce the price by 30%. This means that there is a reduction in the original amount of the sweater by 30% which is expressed as

30/100 × 30 = $9

The new price of the sweater would be 30 - 9 = $21

Since a sales tax of 5% will be added to the final purchase price, the value of the tax would be

5/100 × 21 = 0.05×21 = $1.05

Jake's total cost would be

21 + 1.05 = $22.05

Adam and.his dad share the cost of the meal in the ratio of 2:3 adams dad pays 52.50 what is the to cost of the meal?
larisa86 [58]
Adam pays for 2/5 of the meal so his father pays for 3/5

3/5  = 52.50
1/5 = 52.50 / 3 = 17.50

so cost of the meal = 5 * 17.50 = $87.50

What is the perimeter of square PQRS?
Citrus2011 [14]
First, we need to find the length of the side of the square.
Use phytagorean theorem to find the length of the side. The side acts as hypotenuse, the distance of x and the distance of y acts as the perpendicular side of a right triangle. For clear understanding, see image attached.

General phytagorean theorem
c² = a² + b²
c represents hypotenuse, a and b are the side perpendicular to each other.

In this case, we could write it as
s² = Δx² + Δy²
s represents the length of the side, Δx represents distance of x, Δy represents distance of y

Plug in the numbers, use two of the vertices
I use (4,-1) and (7,3)
s² = Δx² + Δy²
s² = (7-4)² + (3 - (-1))²
s² = 3² + (3 + 1)²
s² = 3² + 4²
s² = 9 + 16
s² = 25
s = √25
s = 5
The length of the side is equal to 5 units length.

Second, find the area of the square
General area to find the area of a square
a = s²

Plug in the numbers
a = s²
a = 5²
a = 25
The area of the square is equal to 25 units area.

A long string with a balloon at the end was tied to the ground. After a breeze came up, the balloon was 55 feet to the right of
Alexxx [7]

Answer:

<em>The slope is 0.55</em>

Step-by-step explanation:

<u>Right Triangles</u>

The string, the ground, and the height of the balloon form a right triangle where the trigonometric ratios are satisfied.

The image below shows the geometric construction. We are required to find the slope the string forms with the ground.

It can be found by using the tangent ratio:

\displaystyle \tan\theta=\frac{y}{x}

Substituting y=30 and x=55

\displaystyle \tan\theta=\frac{30}{55}

\displaystyle \tan\theta=0.55

The slope is 0.55
