At the end of a snow storm,Allison saw there was a lot of snow on her front lawn.The temperature increased and the snow began to melt at a steady rate.After the storm,the snow started to melt at a rate of 0.75 inches per hour and is known that 4 hours after the storm ended,the depth of snow was down to 9inches.Write an equation for the function S(t),representing the depth of snow on Allison lawn,in inches,t hours after the snow stopped falling

Answers

Answer 1

Answer:

The equation for the snow in the lawn after t hours and melting at a rate of 0.75 inches per hour will be equal to S = x - 0.75(t).

What is an expression?

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the given information in the question,

Let the initial amount of snow in the lawn is x inches.

Rate of melting of snow per hour = 0.75 inches per hour.

The equation for t hours, after melting of ice,

S = x - 0.75(t)

Here, t is the time in hours and x is the initial amount of ice in the lawn.

Find the area?????????

Answers

If we slice this down the middle and fit it together like a puzzle we'll get a rectangle base 9.6/2 and height 4.8+9 so area (9.6/2)(4.8+9) = 66.24 square units.

Choice d

Think of the area divided into two parts.

A rectangle, 4.8 units by 9.6 units,

and a triangle with base 9.6 units and height 9 - 4.8 = 4.2 units.

Find the areas of the rectangle and triangle and add them.

Rectangle:

A = LW = 4.8 * 9.6 = 46.08

Triangle:

A = bh/2 = 9.6 * 4.2/2 = 20.16

Add the areas:

46.08 + 20.16 = 66.24

Answer: d. 66.2 units^2

Tyler wants to buy a new television that costs $312. He has already saved $96. He plans to save $24 per week over the next few weeks. Which shows the number of weeks Tyler will need to save to be able to buy the television?

Answers

it will take him 9 weeks

let w be the number of weeks

312 is the total number needed
therefore
312=24w+96
312-96=24w
216=24w
216/24=w
9=w
he needs 9 weeks

Draw two different shapes, each with an area of 6 square units and a perimeter of 12 square units

Answers

The shapes having area of 6 square units and a perimeter of 12 units is shown below.

What is Area and Perimeter?

The total space occupied by a flat (2-D) surface or the shape of an object is defined as its area. The area of a plane figure is the space enclosed by its boundary. The number of unit squares that cover the surface of a closed form is the figure's area.

The perimeter of a shape is the distance around its edge.

We have the figure attached below.

First, the Area of First Figure

= 6 x 1

= 6 unit

and, Perimeter of First Figure

= 1 + 1 + 1 + 1 + 1 + 1+ 1 +1 + 1 +1 +1 + 1

= 12 unit

Second, the Area of Second Figure

= 6 x 1

= 6 unit

and, Perimeter of Second Figure

= 2 + 1 + 2+ 2 + 4+ 1

= 12 unit

Joanne buys a rectangular rug with an area of 35/4 square meters. The length of the rug is 7/2 meters. what is the width, in meters, of the rug?

HELP!!!!!

Answers

There are several information's of immense importance already given in the question. Based on those information's the answer can be easily deduced.
Area of the rectangular rug = 35/4 square meters
Length of the rug = 7/2 meters
Let us assume the width of the rug = x meters
Then
Area of the rug = Length * width
35/4 = (7/2) * x meters
x = (35/4) * (2/7) meters
= 5/2 meters
So the width of the rectangular rug is 5/2 meters.

Answer:

5/2 meters
