Answer:
[tex]6\pi[/tex] or approximately [tex]18.85[/tex] units
Step-by-step explanation:
The formula for finding the circumference of a circle is [tex]C=2\pi r[/tex], where [tex]C[/tex] = circumference and [tex]r[/tex] = radius. In this case, [tex]r=3[/tex], so after plugging that into [tex]C=2\pi r[/tex], we get:
[tex]C=2\pi r\\ = 2*\pi *3\\=6\pi[/tex]
Since [tex]\pi[/tex] is approximately [tex]3.1415[/tex], [tex]6\pi =6*3.1415=18.849[/tex], which rounds to [tex]18.85[/tex]. Therefore, the circumference of the circle is [tex]6\pi[/tex], or approximately [tex]18.85[/tex] units. Hope this helps!

What number is the first multiple of 5 that is greater than 17
Answer:
20
Step-by-step explanation:
Multiples of 5 are: 5, 10, 15, 20, 25, 30, 35, 40, etc. Each multiple is created by multiply 5 times some other number.
The first multiple of 5 that is greater than 17 is 20.
What are multiples of a number?Multiples of a number is simply it's table.
We know 5 has a multiple of 20 which is 5 times 4 and we also know that
20 > 17.
Now the previous multiple of 5 before 20 is 15 which is not greater than 17 and 25 is also a multiple of 5 but 20 comes before 25.
So, the most appropriate multiple of 5 that is greater than 17 that is greater than 17 is 20.

Answer:
[tex]x^{2}-2x-24[/tex]
Step-by-step explanation:
First, expand the parentheses using multiplication:
[tex](x^{2} -2x+9x-18) -9x-6[/tex]
Now we simply combine life terms, giving us:
[tex]x^{2}-2x-24[/tex]
Hope this helps!
Hi there! Let's solve this step-by-step!
We need to expand (x + 9)(x - 2) by multiplying the two terms. We can use this rule: (A+B)(C+D)+AC+AD+BC+BD=
In the problem, (X+ 9)(x-2) -9x- 6
The resulting expression will consist of 4 terms:
First term: x and x
Second term: x and -2
Third term: 9 and x
Fourth term: 9 and -2
Now, we expanded (X+ 9)(x-2) to (xx ⋅ 2 + 9x - 9 ⋅ 2)
Our new problem is: (xx ⋅ 2 + 9x - 9 ⋅ 2) - 9x - 6
Now, we need to combine like factors in this term (xx) by adding up all the exponents and copying the base. No exponent implies the value of 1.
The like factors are: x and x
[tex](x^1^+^1-2x+9x-18)-9x-6[/tex]
Now, your answer is: [tex]x^2-2x-24[/tex]

The work in an office takes 150 hours to complete every week.
Each person in the office works for 32 hours a week.
What is the smallest number of people needed to complete the work?
Answer: A minimum of 5 people will be needed.
Step-by-step explanation:
150/32 = 4.6875
You can't have a partial person, so round up to 5.
It may be possible to have 4 employees working 32 hours and another working 22 hours, but that is not what the question asks exactly. That is still 5 people.

Ada Lovelace had 210 minutes to read, play soccer, and code her computer.
She spent t minutes reading
She spent 2(t +18) minutes playing soccer
She spent 30 minutes coding.
How many minutes did Ada spend reading
Answer:
She spent 48 minutes reading
Step-by-step explanation:
Here, we want to calculate the number of minutes spent reading
By adding all the breakdown of individual tasks, we get the total
Thus, mathematically;
30 + 2(t + 18) + t = 210
30 + 2t + 36 + t = 210
3t = 210-30-36
3t = 144
t = 144/3
t = 48
From the question, she spent t minutes reading which means she spent 48 minutes reading

Find the measure of the missing angle.
32 a
Answer:
Soln,
32°+a=90°[right angled triangle]
or,a=90°-32°
or,a=58°
•°•a=58°
The measure of the missing angle is, a = 58 degree
Used the concept of complementary angle that states,
The sum of complementary angles is always equal to 90 degrees.
Given that,
There are two angles shown in the image.
From the given image,
Angle a and 32 are complementary angles.
Hence,
a + 32° = 90°
a = 90° -32°
Therefore, the missing angle is,
a = 58 degree

If there are 68 people in a survey (everyone is either an adult or kid) and 60% are kids, how many adults are there?
Answer:
about 27 adults
Step-by-step explanation:
68 x 60% would find you kids
100% is 68, so, 100 - 60 = 40%
The remaining 40% are adults.
68 x 0.4 = 27.2
about 27.2 adults
Answer:
27 adults (rounded)
27.2 (not rounded)
Step-by-step explanation:
60% of 68 is 40.8
68 - 40.8 = 27.2
since .8 is bigger than .2 , 40.8 will be 41 and 27.2 will be 27
