With shapes like these, you need to split it into parts you can find the area for and add it together at the end.

Let's take the rectangle out of the two other triangles first,

15x8=120. First area solved.

Now remember, you find areas of triangles by bxh/2. Let's do the one on the side first. 9x8=72. 72/2=36. Second area solved.

The final triangle has a height of 7 m, and it's parallel to the 15 m length from before. 7x15=105, 105/2=52.5. Last area found.

Now let's add them all together. (120+36+52.5)=208.5.

Hope this helped!

Answer:

200π cm^2

Step-by-step explanation:

Sb = 8^2 π = 64π cm^2

a = sqrt2 [8^2 + 15^2] = sqrt2 [64 + 225] = sqrt (289) = 17 cm

Sl = 8x17xπ = 136 π cm^2

SA = 136π + 64π =200π cm^2

Answer:

10/3 or reduced to 1 1/3

Step-by-step explanation:

So mutiplying  equations are pretty simple. But we can notice that we have a number instead of a fraction. When we see this, a thing that automatically goes through my head is, that a number as a fraction is also 5/1. From there you equation is now 2/3x5/1. We can now multiply the top two numbers and the bottom two numbers. Which equals 10/3.

☁️ Answer ☁️

10/3

Here's the mixed number form:

Step-by-step explanation:

Answer:

$140.74

Step-by-step explanation:

Assuming this is a decaying exponential function, we can find a model for the depreciation in the form of v = a(b^t)

At t = 0, we get 5000 = a(b^0), which gives us a = 5000

At t = 1, we get 4000 = 5000b, such that b = 4/5

Now that our function is defined as v = 5000(4/5)^t, we can plug in t = 16 to solve for the value of the piano.

v = 5000(4/5)^16, which is approximately $140.74.

The expression  [tex]\frac{5}{2} \times \frac{3}{10}[/tex] in the simplest form can be written as [tex]\frac{3}{4}[/tex].

Mathematically, an expression is a collection of numbers, variables, mathematical operations, functions, and often symbols combined according to peculiar rules to represent a mathematical calculation or association. It can be supposed to as a mathematical idiom or formula.

By combining numbers, variables, operators, and functions, mathematical expressions can represent a wide range of calculations and associations.

The given expression is [tex]\frac{5}{2} \times \frac{3}{10}[/tex].

[tex]\frac{5}{2} \times \frac{3}{10} = \frac{1}{2} \times \frac{3}{2}[/tex]

          [tex]= \frac{3}{4}[/tex].

Hence, the fraction is [tex]\frac{3}{4}[/tex].

Answer:

A = 27.2 mm²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 8 and h = 6.8 , then

A = 0.5 × 8 × 6.8 = 4 × 6.8 = 27.2 mm²

Answer:

the equation that should be required is 0 = 2t

Step-by-step explanation:

Let us assume the hours of television be t

And, for hours outdoor be o

As the hours outdoors would be twice the hours of television so the equation is

0 = 2t

Therefore the equation that should be required is 0 = 2t

The same is  relevant

Answer:

o = 2t

Step-by-step explanation:

You will spend 2 times as many hours outdoors as you spend watching TV. The number of hours you spend outdoors depends on t, the number of hours you spend watching TV.

To find the number of hours you will spend outdoors, o, you can use the equation o = 2t

Remember, you want to find the number of hours you will spend outdoors if you spend  4 hours watching TV and 8 hours watching TV.

8 = 2 x 4

16 = 2 x 8

Now we can turn the values from the equation into ordered pairs in the form (x , y).

The ordered pairs are (4 , 8) and (8 , 16).
