Answer:
2.3
Step-by-step explanation:
First off, you start with the circumference formula which is 2(pi)r. Since we know our circumference, we can create the equation solving for r. so we have 15=2(pi)r. Now in order to solve for r, we need to transfer everything to the other side, meaning dividing by 2(pi). So 15/2(pi)=2(pi)r/2(pi). Since we are using 3.14 for pi, 3.14*2 is 6.28. 15/6.28 which is about 2.388 So the radius of the circle is 2.3 (rounded to the nearest tenth)

What expression is equivalent to 9(3x + 8)? *
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.

b=2x^2(x-5) divided by 10x solve b if x=10
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.
What is an expression?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.

What’s the area for each figure?
9514 1404 393
Answer:
52.5 in²52.5 in²76.97 in²total: 181.97 in²Step-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.

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.)

John sells candy bars for 2$ each. How much will he make if he sells 10 bars
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

A runner runs at an average speed of 9 m/s for 20 seconds
How far did the runner run in metres?
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
