Find the area of the composite figure?
Answer:
128
Step-by-step explanation:
Let's start by figuring out the last side of the triangle
we can use the pathagoryous theroem and get
11.9²+x²=16.9²
Solve this and get x=12
Let's now compute the area of the triangle
b*h*.5
12*11.9*.5=71.4
So 71.4 is the area of the triangle
we now need to find the area of the semi circle.
to do this we are going to find the area and then divide it by 2
We know that the length is equal to 12 which means that the radius is 6
so we have
π6²/2
which is 56.55
We add the 71.4+56.55= 127.94 which rounds to 128
Answer:
212.758
Step-by-step explanation:
Find the semi-circle first, the diameter is 16.9 ft.
To find area:
Formula:
pi x radius x radius x 1/2
16.9 ÷ 2 = 8.45 (radius)
22/7 x 8.45 x 8.45 = 224.407 (Circle)
224.407 ÷ 2 = 112.203 (Semi circle)
Find the triangle:
1/2 x base x height or length x base x height
But for now, we will use the first one.
1/2 x 16.9 x 11.9 = 100.555
Now add them up.
100.555 + 112.203 = 212.758

7a - 4a for a = 8 Anyone know the answer?
Answer:
the answer is 24
Step-by-step explanation:
hoped I helped:)
The value of the expression for x=8 is 24
What are like and unlike terms in an expression?In Algebra, the like terms are defined as the terms that contain the same variable which is raised to the same power. In algebraic like terms, only the numerical coefficients can vary. We can combine the like terms to simplify the algebraic expressions
Given here: The expression as 7a-4a
Now combining the like terms we get
7a-4a=3a
for a=8
we have
3a=3×8
=24
Hence, The value of the expression for x=8 is 24

11. What is the measure of each interior angle of a
regular pentagon?
12. The exterior angles of any polygon add to

Answer:
Step-by-step explanation:
10. To solve for this, use the formula: 180*(n-2)
So, 180(n-2) = 2,340
Once n is solved for, that is the number of sides
11. Use the formula:
[180*(n-2)]/n

Lin runs 5 laps a track in six minutes how many minutes per lap is that
Answer:
1.2 minutes
Step-by-step explanation:
6 divided by 5 = 1.2
To do this, you take the total number of minutes, which is 6, and divide by the number of laps that Lin ran, which was 5.
Answer:
1.2 minutes
Step-by-step explanation:
5 laps/6 minutes = 1 lap/x minutes
To convert the ratio from 5 laps to one laps, 5 was divided by 5. Therefore, to keep the same ratio, 6 must also be divided by 5, making the answer:
1 lap/1.2 minutes
