Question 5 options:
Answers
Step-by-step explanation:
l = 12 metres
b = 15 metres
diameter of semicircle = length = 12 m
radius = 12/2 = 6 cm
area of the figure = area of rectangle + area of semi circle
= l × b + πr²
= 12 × 15 + 3.14 × 6²
= 180 + 113.04
= 293.04 m²
The perimeter of the figure is 60.84 meters.
What is a rectangle?A rectangle is a quadrilateral with all four interior angles 90°.
Given that, the width and height of the rectangle are 15 meters and 12 meters respectively.
Note that the diamter o he semicircel is 12 meters.
The radius of the semicircle is:
12/2
= 6 meters
The perimeter of the figure is given by:
15 + 12 + 15 + π(6)
= 42 + 3.14×6
= 60.84
Hence, the perimeter of the figure is 60.84 meters.

12v = 48 + 4v
helpp p
Answers
Answer:
Therefore, the solution to the equation 12v = 48 + 4v is v = 6.
Step-by-step explanation:
To solve for v in the equation 12v = 48 + 4v, you can start by simplifying the equation by moving all the v terms to one side and all the constant terms to the other side:
12v - 4v = 48
Simplifying the left side of the equation gives:
8v = 48
To solve for v, you can divide both sides of the equation by 8:
v = 6
Therefore, the solution to the equation 12v = 48 + 4v is v = 6.
Answer:
Step-by-step explanation:
12v = 48 + 4v
Your first step is to subtract v from both sides:
8v = 48
Then, you divide each sides by 8 which gives you:
v = 6
That's your answer!

Frank finds 9 coins on the floor of his car, and 3 of them are quarters. If he finds 15 more coins on the ground, at the same ratio as the coins found in the car, how many more coins will most likely be quarters?
Answers
3 is 1/3 of 9, meaning the probability of picking up a quarter is 1/3, if he finds 15 more,
15/3 is 5.
5 coins should be quarters
Answer: 5 coins
Step-by-step explanation:
Frank found 9 coins on the floor of his car, and 3 of them were quarters. This means that 3 out of the 9 coins, or \(\frac{3}{9}\), were quarters.
Simplifying this fraction, we get \(\frac{1}{3}\) of the coins found in the car were quarters.
If Frank finds 15 more coins on the ground at the same ratio, then \(\bold{\frac{1}{3}}\) of these coins will also be quarters. To find out how many quarters he will most likely find, we need to find \(\bold{\frac{1}{3}}\) of 15:
\(\large \frac{1}{3} \times 15 = 5\)
Therefore, Frank will most likely find 5 more quarters on the ground, assuming he finds coins at the same ratio as he did in his car.

So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

The same art teacher estimates that he has enough clay for 9 students. Is he correct? Why?
Remember: He has 47 1/3 pounds of clay and wants to give each student 2 1/2 lbs of clay.
*Use compatible numbers to estimate. These are numbers that are close to the actual numbers that you know will divide easily.
Answers
Answer:
The art teacher is incorrect.
Step-by-step explanation:
Coming Up with Compatible Estimate Numbers:
The teacher has 47 1/3 pounds of clay. We can round this to 50. Now we have 50 pounds of clay.
Explaining the Operations:
The teacher wanted to distribute the clay by 2.5 lbs. This means we need to divide the amount of clay by 2.5.
Performing the Operations:
Divide 50 by 2.5 ---> 50÷2.5=(5÷2.5)*10--->5÷2.5=2--->2*10=20
Final Conclusion
For every student, the art teacher plans to give 2.5 lbs of clay. This means he will divide his 47 1/3 pounds by 2.5 piles and hand them out to the students. If we round 47 1/3 to 50 (about 2 points higher) and divide 50 by 2.5, you get 20. This means he would have a little less than enough clay for 20 students, not 9. Therefore, the art teacher is incorrect.
****ANOTHER POSSIBLE SOLUTION****
You can also multiply 9 x 2.5 and see if the product is close to 47 1/3. In this case, you can round 2.5 to 3 and proceed with the multiplication. 9*3=27 Since 27 is a lot lower than 47 1/3, the art teacher is incorrect.

Answer:
∠1 and ∠2 are supplementary angles.
∠6 and ∠8 are vertical angles
∠1 and ∠5 are corresponding angles.
Step-by-step explanation:
∠1 and ∠2 lie on a straight line which will always add up to 180 degrees or supplementary.
∠6 and ∠8 lie opposite each other on the transversal (intersecting line) and are equal.
<1 and <2 are Supplementary angles
<1 and <5 are Corresponding angles
<6 and <8 are Vertical angles
Given that d II e
when a transversal intersects two parallel lines the following conditions are true:
Supplementary angles are those angles when the sum of two angles is equal to 180 degrees. Since <1 and <2 are on either side of the transversal their sum is equal to 180 degrees hence why it's a supplementary angle.
Vertical angles form 4 angles when a line intersects them and the two angles are opposite to each other. In this case <6 and <8 are opposite each other hence why they are vertical angles.
Corresponding angles are the angles that are in the same position on each of the parallel lines and on the same side of the transversal. In this case both <1 and <5 are on the same side of the transversal on each of the parallel lines hence why they are corresponding angles

Three research departments have 8 ,10 , and 7 members, respectively. Each department is to select a delegate and an alternate to represent the department at a conference. In how many ways can this be done?
Answers
We can conclude that exists 211680 ways.
How many ways can this be done?We know that the three research department is have 8, 10, and 7 members.
We choose a delegate and an alternate to represent the department.
First case: department have 8 members.
So, for a delegate, we have 8 options, and for a alternate 7, so a total of
\(8 \times 7 = 56 \ \text{options}\)
Second case: department have 10 members.
So, for a delegate, we have 10 options, and for a alternate 9, so a total of
\(10\times 9 =90 \ \text{options}\)
Third case: department have 7 members.
So, for a delegate, we have 7 options, and for a alternate 6, so a total of
\(7\times6 = 42 \ \text{options}\)
Therefore, we get:
\(56 \times 90 \times 42 = \bold{211680}\)
Hence, we conclude that exists 211680 ways.
For a similar problem about this, please click the link below:
https://brainly.com/question/30958797
For the first department with 8 members, there are 8 choices for selecting a delegate. After choosing a delegate, there remain 7 members, so there are 7 choices for selecting an alternate. Therefore, there are 8 × 7 = 56 ways to select a delegate and an alternate from the first department.
Similarly, for the second department with 10 members, there are 10 choices for selecting a delegate and 9 choices for selecting an alternate. Hence, there are 10 × 9 = 90 ways to select a delegate and an alternate from the second department.
For the third department with 7 members, there are 7 choices for selecting a delegate and 6 choices for selecting an alternate. Thus, there are 7 × 6 = 42 ways to select a delegate and an alternate from the third department.
To find the total number of ways to select delegates and alternates from all three departments, we multiply the number of choices for each department together:
56 × 90 × 42 = 211,680.
Therefore, there are 211,680 ways to select a delegate and an alternate from each department.
