Step-by-step explanation:

1, 2. The area of each triangle is given by the formula ...

  A = (1/2)bh . . . . . for base b and height h

The area of the given triangle is ...

  A = (1/2)(7 in)(15 in) = 105/2 in² = 52.5 in²

Triangles 1 and 2 have the same dimensions, so have the same area.

  Figure 1 area: 52.5 in²

  Figure 2 area: 52.5 in²

__

3. The area of the semicircle is given by the formula ...

  A = (1/2)πr² . . . . for a semicircle of radius r

This semicircle has a radius of 7 in, so an area of ...

  A = (1/2)(3.1416)(7 in)² ≈ 76.97 in²

  Figure 3 area: 76.97 in²

__

The total area is the sum of these:

  52.5 in² + 52.5 in² +76.97 in² = 181.97 in²

  Composite Figure area: 181.97 in²

_____

Comment on decimal digits

We cannot tell your rounding requirements. Here, we have rounded to the nearest hundredth. If you use the value 3.14 for pi, then your areas for the semicircle and composite figure will end in .93, not .97.

I did the test and got it right.

Answer:

The answer would be 180 meters.

Step-by-step explanation:

We are told the runner runs at 9 m/s for 20 seconds.

Since they run 9 meters per second, all we have to do is multiply 9 by 20, which will give us 180 meters.

9 x 20 = 180

Answer:

answer is 10

Step-by-step explanation:

2x^2(x-5) /10x

x=10

so,

=2*10^2 (10-5) / 10*10

=2*100(10-5) /100

=200*5 / 100

=1000/100

=10

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The value of b when x = 10 is 10.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

b = 2x² (x - 5) ÷ 10x

When x = 10 find b.

Now,

b = (2x² (x - 5))/ 10x

Substitute x = 10

b = 2 x 10² ( 10 - 5) / 10 x 10

b = 200 x 5 / 100

b = 10

Thus,

The value of b when x = 10 is 10.

Step-by-step explanation:

Step-by-step explanation:

This is what it is equal to:

9×3x=27x

9×8=72

Therefore it will be:

[tex]27x + 72[/tex]

hope it helps!

Answer:

27x+72

Step-by-step explanation:

You have to use the distributive property to simplify the expression. Therefore, you have to  multiply both terms inside the parentheses.

1. 9*3x=27x

2. 9*8=72

They could not be added together, as they are not like-terms. So, you just write it down as 27x+72.

Actually Welcome to the Concept of the Similar Triangles.

Since here we can see that, similar triangles different by size of the side by 0.5 ration,

hence,the value of x = 0.5 times of MN

hence, x = 5/2

so the mixed fraction representation is given as,

[tex]2 \times \frac{1}{2} [/tex]

mixed fraction ration is 2(1/2)

===> hence option is B.)

Step-by-step explanation:

Average gain = Net gain / Five day

Average gain = -50 / 5

Each Candy Bar is $2, so if he sells 10, you just need to multiply,

10 * $2 = 20

So He'll make $20, selling 10 bars.

If he sells 50 bars then just multiply,

50 * $2 = 100

So He'll make $100 selling 50 bars.

Answer:

he will make $20 dallors
