If a circle has a circumference of 81.64 cm, what is the radius?
Answer:
c = Circumference=pid= 81.64 To find the radius of a circle you can just divide the diameter by 2.
pi = 3.14
d = diameter=c/3.14 Pi is always 3.14 or 22/7.
d = 81.64/3.14
d = 26
r= radius= 26/2
radius=13 cm

Find the volume of this prism 5cm,12,cm 15cm,6cm 8cm
Answer:
840 cm³
Step-by-step explanation:
In the figure attached, the prism is shown.
The prism can be divided into two rectangular prisms, one at the top, with dimensions 5 x 4 (= 12 - 8) x 6 cm, and the other one at the bottom with dimensions 15 x 6 x 8 cm.
Area of the first prism: 5*4*6 = 120 cm³
Area of the second prism: 15*6*8 = 720 cm³
Then, the volume of the complete prism is 120 + 720 = 840 cm³
The required total volume of the complete prism is 840 cm³.
We have to determine, The volume of the prism 5cm,12,cm 15cm,6cm 8cm.
According to the question,
The prism can be divided into two rectangular prisms,
First part at the top, with dimensions [tex]= 5 \times 4 \times( 12 - 8) = 5\times 4 \times 6 cm,[/tex]
And the other part one at the bottom with dimensions [tex]= 15 \times 6 \times 8 cm.[/tex]
Area of the first prism: [tex]5\times4\times6 = 120 cm^{3}[/tex]
Area of the second prism: [tex]15\times6\times8 = 720 cm^{3}[/tex]
Then, The Total volume of the complete prism is 120 + 720 = 840 cm³
Hence, The required total volume of the complete prism is 840 cm³.

Evaluate 12 − 6 + (14 − 8)2 = ____________. (1 point)
Answer:
18
Step-by-step explanation:
you do PEMDAS
there is parenthesis
12-6+6 times 2
there is multiplication
12-6+12
then there is subtraction and addition so you have to do it left to right
18
Answer:
18
Step-by-step explanation:
When solving these types of questions, you want to remember PEMDAS. According to PEMDAS, P is parenthesis. (14-8) is in parenthesis. 14-8 is 6.
Now the equation looks like this:
12-6 + (6)2
There are no Exponents in this equation, but there is multiplication. If there are no operations between two integers, that means it is likely to be multiplication. 6 x 2 is 12.
Now the equation looks like this:
12-6+ 12
Even though, according to PEMDAS, Addition is before subtraction, you can do either one from left to right. Even with multplication and division.
Now the equation looks like this:
6+12
Obviously 6+12 is 18. So, 18 is the answer.

Hi again! I need help with another question. "What is a possible third side to a triangle with side lengths of 14 and 5?
A. 9
B. 8
C. 5
D. 12"
Answer:
D
Step-by-step explanation:
Remember that the sum of any 2 sides of a triangle always must be greater than the length of the third side.
A. 9 + 5 = 14 so NO
B. 8 + 5 = 13 which is less than 14 so NO
C. 5 + 5 = 10 which is less than 14 so NO
D. 12 + 5 = 16 which is greater than 14.
12 + 5 > 14
14 + 12 > 5
5 + 14 > 12
It works for all 3. That means the answer is D.
a car rental company rents vehicles to groups one group rented 5 vans and 2 cars to fit 70 people another group rented 3 vans and 4 cars to fit 56 people each vehicle was completely filled how many people fit in a van how many people fit in a car
Answer:
12 people fit in a van, 5 fit in a car
Step-by-step explanation:
v is people in a van, c is people in a car
5v+2c=70
3v+4c=56
5v+2c=70
2c=70-5v
c=35-2.5v
now use substitution to plug in c
3v+4(35-2.5v)=56
3v+140-10v=56
140-7v=56
-7v=-84
v=12
now we know v, plug it in to find c
5(12)+2c=70
60+2c=70
2c=10
c=5
12 people fit in a van, 5 fit in a car

Given right triangle MNL, what is the value of cos(M)?
Three-fifths
Three-fourths
Four-fifths
Five-thirds
Answer:
4/5
Step-by-step explanation:
took it on edg
The value of cos(M) is determined as Four-fifths (4/5).
Length of adjacent side of the right triangle
The length of the adjacent side of the right triangle is calculated as follows;
adj² = hyp² - opp²
adj² = 25² - 15²
adj² = 400
adj = √400
adj = 20
Value of cos(M)
Cos (M) = adj/hypo
Cos (M) = 20/25
Cos (M) = 4/5
Thus, the value of cos(M) is determined as Four-fifths (4/5).

The literary device known as repetition is used to emphasize the same concept or idea or to communicate a particular message by repeatedly using it.
What is repetition?Although repetition typically relates to sentences or words, it can also be present in the sounds that words make. There are three different techniques to show repeat with noise. Consonance, harmony, starting, and alliteration are the names of these three literary devices.
The term "as usual" is repeated in this situation to emphasize how nothing exceptional was going on; it was just the block bash as usual. The predictability demonstrates that everyone's attitudes and behaviors were uniform and fairly predictable. That is wanted to predict the neighborhood and how they act in a certain way

The bill at a restaurant is 37.52. Helen wants to leave a 15% tip. If Helen has $40, will she have enough money to pay the bill?
Answer:
No, she will go $3.15 above 40.
Step-by-step explanation:
1. Since the tip is 15%, you can either multiply 37.52 by 1.15 or 0.15. In the route of multiplying by 0.15, you need to add it to 37.52. I will multiply by 1.15 to make it easier.
2. 37.52x1.15 = 43.148 or about $43.15 (rounded).
