Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1 and 3/5 doors. How many liters of paint are needed for one door? Consider drawing a model to help you solve the problem.

Answer:

29

To solve, you must isolate the variable. This means moving the variable and it's coefficient to the other side of the equation with only the same variable on the same side with all the constants on the other side.

If you multiply, divide, add, subtract, square root, exponent both sides of the equation by the same value, that end value stays the same.

Terminology

Variable: Any letter than stands for a value than can be solved and change value. (i.e. x, y, z, a, etc.)

Coefficient: The number right before a variable (without being separated by an operator). It is a multiplication factor for a variable. Basically, it's just a way to express what you are multiplying a variable by.

If the coefficient is 1, it means [variable] * 1. 1[variable]

Subtract 23 on both sides.

29 - 23 = v + 23 - 23

v = 29

Answer:

The scale factor for area is found by squaring the scale factor for length. Thus the scale factor for area is s2. If this is reversed, a method is provided for solving the problem being investigated. The scale factor for area is 2.

Answer:

The area of the composite figure can be calculated by breaking it down into separate geometric shapes and calculating the area of each shape. The figure can be divided into a rectangle and a triangle. The rectangle can be calculated by multiplying the length (16 feet) by the height (22 feet) resulting in 352 ft^2. The triangle can be calculated by multiplying the base (4 feet) by the height (8 feet) and dividing by 2, resulting in 16 ft^2. By adding the area of the rectangle and the triangle, we get 352 ft^2 + 16 ft^2 = 368 ft^2. So, the total area of the figure is 368 ft^2. Therefore, the correct answer is 440 ft2.

Step-by-step explanation:

above

If a five-sided figure with two parallel sides and the shorter one is 16 feet.  The figure that  represents the total area of the figure is: C. 440 ft2.

The rectangle is formed by the two parallel sides, which are 16 feet long.

The height= 22 feet.

The area of the rectangle =  16 feet x 22 feet

The area of the rectangle = 352 square feet.

The triangle is formed by the vertex, the perpendicular height, and the 4-foot side. The area of a triangle is (base x height) / 2.

Since the base of this triangle is 8 feet and the height is 22 feet.

The area of the triangle = (8 x 22) / 2

The area of the triangle= 88 square feet.

The total area of the composite figure is :

Total area = 352 square feet + 88 square feet

Total area  = 440 square feet

Therefore the correct option is C.

The formula for the surface area of a cylinder is [tex]2\pi rh+2\pi r^{2}[/tex]. Using this, you can calculate that the cylinder's total surface area is 56[tex]\pi[/tex]. But, since Adrian only needs to find the surface area outside of the tire, I'm going to assume that you only need to apply [tex]2\pi rh[/tex] to your problem. Therefore, the answer is 24[tex]\pi[/tex] or 75.4 (rounded to the nearest tenth). I hope this helps!

Answer:

60

Step-by-step explanation:

given: length = 10m + width

perimeter = 220

find length of backyard

Solution

let us assume width = x

length = 10 + width

10 + x

perimeter of rectangular backyard = 2( length + width)

= 220 = 2 ( 10 + x + x )

= 220 = 2 ( 10 + 2x )

= 220 / 2 = 10 + 2x

= 110 - 10 = 2x

= 100/2 = x = 50

so, according to above solution and Q.

width = x = 50

length = 10 + width = 10 + x = 10 + 50 = 60

So the answer is 60
