Bobby has a party while his parents are away for the weekend. Bobby estimated that if his 9 friends hep him to clean the house, they will finish in time if they start 8 hours before his parents return. But after only two hours of cleaning, Bobby's parents call and say they are just two hours from home. How many more friends does Bobby need to call to help finish cleaning in time.
The number of more friends that Bobby need to call to help finish cleaning in time is 20 friends.
Number of additional friends neededLet x represent number of more friends
Number of hours=8×(9+1)
Number of hours=8×10
Number of hours=80 hours
Hence:
10×2+2(10+x)=80
20+20+2x=80
Collect like terms
2x=80-40
2x=40
Divide both side by 2x
x=40/2
x=20 friends
Therefore the number of more friends that Bobby need to call to help finish cleaning in time is 20 friends.

Find the volume of this compound figure.
Hint: Half a sphere and a cylinder
Use 3.14 for pi!
The volume of the given shape will be equal to V=2827.42 cubic inches.
What is volume?The volume is defined as the space occupied by the object in the three-dimensional plane. It requires three coordinates to find the volume of any object.
Here it is given in the question that:-
Radius of the semicircle=12 inches
Height of the cylinder =13 inches.
Now the volume will be calculated as:-
Total volume of the figure will be the sum of the Volume of the semicircle and the Volume of the cylinder.
= 2πr³+πr²l
= 2xπx(6)³+πx(6)²x13
=1357.16+1470.26
=2827.42 Cubic inches
Hence the volume of the given shape will be equal to V=2827.42 cubic inches.

To determine whether students

surveys every 25th student from an
alphabetized list of students in the
school. Will the survey results from
this sample support a valid inference?
Explain.
Using sampling concepts, it is found that the sample would not support a valid inference, as both alphabetized and non-alphabetized students should be sampled.
What is sampling?It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.
The school has both alphabetized and non-alphabetized students, and both groups should be sampled for a valid inference to be made. Since only alphabetized students are sampled, the sample would not support a valid inference.

The equilateral triangle shown is rotated about line a. each side of the triangle measures 20 mm. an equilateral triangle is shown. line of rotation a goes through one point and the midpoint of the opposite side. what shape is created by the rotation and what is the approximate circumference of the base? circumference of a circle: c = 2πr a cylinder with a circumference of about 63 mm a cylinder with a circumference of about 126 mm a cone with a base circumference of about 63 mm a cone with a base circumference of about 126 mm
The circumference of the circle based on the equilateral triangle is 63mm.
How to calculate the circumference?The side of the triangle is 20mm. The radius will be:
= 20/2 = 10
The circumference of the circle will be:
= 2πr
= 2 × 3.14 × 10
= 63
In conclusion, the circumference is 63mm.

Answer:
a cone with a circumference of about 63 mm
Step-by-step explanation:
By imagining the triangle rotating around the line in the middle, we can see that the triangle will create a cone, not a cylinder.
If one side of the triangle measures 20 mm, then the radius at the base of our cone will be 10 mm. (20 mm is the diameter and the radius is half of that.)
Use 2πr to solve for the circumference and it comes out to 63.
Thus, the rotated triangle will created a cone with a base circumference of about 63 mm.
What is the slope of the line through the points (-2, -1) and (4, 3)?
Ans: 2/3
Step-by-step explanation:
Formula : [tex]m = \frac{y2 - y1}{x2- x1}[/tex] (Then replace the number in )
= 3- (-1) / 4 - (-2) = 4 / 6 = 2 / 3
Step-by-step explanation:
the slope is always the ratio "y coordinate change / x coordinate change" when going from one point on the line to another.
so, when going from (-2, -1) to (4, 3)
x changes by +6 (from -2 to 4).
y changes by +4 (from -1 to 3).
therefore, the slope is
+4/+6 = 4/6 = 2/3
