plsss help. Thanks!!
Answer:
401
Step-by-step explanation:
1. Approach
To solve this problem, one first has to think about the given figure in a certain way. In the figure, one can see that it is a circle attached on either side of a rectangle. To find the perimeter of the figure, one has to find the circumference of the circle and then add two sides of the rectangle to the answer
2. Circumference of the circle
The formula to find the circumference of a circle is;
[tex]2r[/tex](pi) or [tex]d[/tex](pi)
~ diameter times the value (pi)
Normally to find the circumference of a semicircle, one would have to divide this formula by 2, but since in this case, one has to add two congruent semicircles, so therefore, the effect of dividing the equation by two, only to multiply by two again cancels, and hence, there is no need to divide by 2.
Substitute in the values;
(78)(pi)
~ 245
3. Find the perimeter of the entire object
Now, one has to add the two additional sides of the figure, to the circumferences of the semicircles to get the final answer;
78 + 78 + 245
= 401

A circular placemat has 44 inches of braid around the edge. What is the area of the placemat to the nearest square inch? Use 3.14 for π.
Enter the correct answer in the box.
[ ]
==========================================================
Explanation:
We'll need to use the circumference formula
C = 2*pi*r
to find the value of the radius r when C = 44
So we get
C = 2*pi*r
44 = 2*3.14*r
44 = 6.28*r
6.28r = 44
r = 44/6.28
r = 7.0063694267516
which is approximate
Then we use this value of r to find the area we need
A = pi*r^2
A = 3.14*(7.0063694267516)^2
A = 154.140127388536
A = 154
The area of the circular placemat is approximately 154 square inches.
Answer:
a ~ 154
a = [tex]\frac{484}{(pi)}[/tex]
Step-by-step explanation:
1. Approach
In this problem, one is given the circumference, the distance around the circle, one must find the area. In order to find the area, one must know the radius of the circle. To find the radius, one has to backsolve from the given circumference, then substitute the derived value into the formula for the area and solve.
2. Find the radius
The formula to find the circumference of a circle is;
[tex]2r(pi)=c[/tex]
Where (r) is the radius, (pi) is (3.1415), and (c) is the circumference.
Substitute in the given values and solve;
[tex]2r(pi) = c\\2r(pi) = 44\\r=\frac{44}{2(pi)}\\r=\frac{22}{(pi)}[/tex]
3. Find the area
Now, one has the value of the radius, substitute it into the formula for the area of a circle and solve;
The formula for finding the area of a circle;
[tex](pi)r^{2}=a[/tex]
Where (pi) is (3.1415), (r) is the radius, and (a) is the area,
Substitute in the value and solve.
[tex](pi)r^{2} = a\\(pi)(\frac{22}{(pi)})^{2}=a\\\frac{(22)^{2}}{(pi)}=a\\\frac{484}{(pi)}=a[/tex]
a ~ 154

A pair of retro Air Jordans is priced at $250 is on sale for 20% off. How much is the discount?
What is the sale price of the sneakers?
Answer: 20% off means that the new price of the shoes will be 80% of the original price:
$30(100% – 20%) = $30(80%)
Converting the percent to a decimal gives:
$30(0.8) = $24.00
There is an additional 15% off the sale price of $24.00, so the final price is 85% of the sale price:
$24(100% – 15%) = $24(85%)
Again converting the percent to a decimal gives:
$24(0.85) = $20.40
Step-by-step explanation:
Answer:
$200

HOW TO WRITE IN DIVISION EXXPRESION I GIVE BRAINLEST
Answer:
I believe that 4 1/2 divided by 6 is the correct answer.
(It is the same as the expression you wrote next to "Regular." It is correct because it does not include an equal sign and correctly expresses the problem.)
Note: Do not include any work below the arrow when writing in the "Expression" section.
Please let me know if this is incorrect.
3(2x-5)= 21
solve it 2 different ways
plzz hurry i need help
Answer:
x = 6
Step-by-step explanation:
3 (2x - 5) = 21
=> 6x - 15 = 21
=> 6x = 21 + 15
=> 6x = 36
=> x = 36 / 6
=> x = 6
OR
3 (2x - 5) = 21
=> 2x - 5 = 21 / 3
=> 2x - 5 = 7
=> 2x = 7 + 5
=> 2x = 12
=> x = 12 / 2
=> x = 6

Step-by-step explanation:
A statistical question is a type of question that can't be answered with just one number or value. It has to have different responses for different types of people in different situations. An example of a statistical question is "What do you do afterschool?" because every person does different things afterschool. The only question that has different responses for different people is the first one, "What is your favorite subject this year?".

Hello!
It would be 24.79 but if the answer were to be rounded, it would be 25
Hope this helps! :)
Answer:
11 6/12
Step-by-step explanation:
Frist find your common denominator then find the new numerator and you get
5 10/12 × 4 3/12 = 9 30/12
9 30/12 is a improper fraction so lets make it proper.
30 goes into 12 two times and you get 2 6/12
9 + 2 6/12 = 11 and 6/12
