Please find the diameter for the cone. Round your answer to the nearest tenth. :)
Answers
Answer:
r = 0.9 in.
Step-by-step explanation:
the volume equation of a cone is πr^2h/3 in this case you have the volume and the height measurements but youre missing the radius, so you have to divide the volume by the rest of the equation and backtrack and when you do, you get a radius value of 0.9

Who earns
Answers
Answer:The expressions for the payment made to Mary are,
(Monday) 90 = 15m + b
(Tuesday) 62 = 8m + b
where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.
The equation that represents Mary's earning is
y = 4x + 30
For 20 students,
y = 4(20) + 30 = 110
For Lisa's earnings,
y = 8x + 15
Substituting 20,
y =8(20) + 15 = 175
Thus, Lisa would earn more than Mary by $65.

Step-by-step explanation:
A group of friends will host a party and split the cost of food and supplies evenly. The cost that each person will pay is inversely proportional to the number of friends who decide to host. If five friends host the party, each person pays $12 for food and supplies. Write an equation that describes the relationship between cost (c) that each host pays and the number of hosts (h).
Answers
Answer:
C=60/h
Step-by-step explanation:
Cost is inversely Proportional to the number of friends who decides to host.
If five (5) friends host the party,
And each friend pays $12 for food and supplies
The equation that describes the relationship is
C=k ×1/h
Where,
C= cost that each host pays
K=constant
h=number of host
Therefore,
$12=k×1/5
$12=k/5
Make k the subject of the formula
$12=k*1/5
Multiply both sides by 5
12×5=k*1/5×5
60=k*5/5
60=k*1
60=k
Sub the value of k into
C=k ×1/h
C=60*1/h
C=60/h

Answer:
[tex]\dfrac{5}{y+5}[/tex]
Step-by-step explanation:
Here, we have to find the sum of 2 fractions:
1st fraction: [tex]\dfrac{3y}{y^{2}+7y+10}[/tex]
2nd fraction: [tex]\dfrac{2}{y+2}[/tex]
Considering the denominator of 1st fraction:
[tex]y^{2}+7y+10[/tex]
Using factorization method:
[tex]7y[/tex] can be written as [tex](2y + 5y)[/tex].
[tex]\Rightarrow y^{2}+2y+5y+10[/tex]
Taking 5 common from [tex]5y+10[/tex] and y common from [tex]y^{2}+2y[/tex]: [tex]\Rightarrow y(y+2)+5(y+2)[/tex]
Now taking [tex](y+2)[/tex] common:

Ed lined up 10 guitar picks across his desk. Each pick weighs 12 mg wide. How many grams does his entire set of guitar picks weigh?
Answers
Answer:
120 milligrams because 12 mg *10 =120
Ed's entire set of guitar picks, with each pick weighing 12 mg and having 10 picks in total is 0.12 grams.
To calculate the total weight of the guitar picks in grams, we first need to know that there are 10 guitar picks and each pick weighs 12 mg.
Knowing that there are 1000 milligrams in a gram, we can convert the weight of one pick into grams:
Weight of one pick in grams = 12 mg / 1000 = 0.012 grams.
Next, we multiply this by the total number of picks to get the combined weight:
Total weight of 10 picks = 0.012 grams pick * 10 picks = 0.12 grams.
So, Ed's entire set of guitar picks weighs 0.12 grams.

Write a coordinate proof to prove that the segment that joins the vertex angle of an isosceles triangle to the midpoint of its base is perpendicular to the base
Answers
Answer:
Slope of the base segment line is zero, hence base segment is horizontal
Slope of the segment that joins the vertex angle to the midpoint of its base is undefined hence the line is vertical
Therefore, angle between base segment line and the segment line from the vertex angle to the midpoint is perpendicular
Therefore, the segment that joins the vertex angle to an isosceles triangle to the midpoint of its base is perpendicular to the base
Step-by-step explanation:
Here we prove the required relation as follows;
Let the isosceles be ABC
The coordinates of the points are
C = (0, 0) (Vertex)
A = (-a, b)
C = (a, b)
P = (0, b) (Midpoint of base)
Therefore, the gradient or slope of the base AC is presented as follows;
[tex]Slope, m \, of \. base, \, AC= \frac{dy}{dx} = \frac{b - b}{a - (-a)} = \frac{0}{2\cdot a} = 0[/tex]
Hence, segment AC is vertical
[tex]Slope, m \, of \, segment \ CP \, joining \, vertex, \, to \, midpoint, P, on \,AC = \frac{0 - b}{0 - 0} = \frac{-b}{0} = Undifined.[/tex]
Hence, segment CP is vertical
Therefore, the segment that joins the vertex angle to an isosceles triangle to the midpoint of its base is perpendicular to the base.
In an isosceles triangle with base BC, the segment from vertex A to the midpoint M of BC is vertical, whereas BC is horizontal. Since vertical and horizontal lines are perpendicular by definition, AM is perpendicular to BC.
Let's assign coordinates to the isosceles triangle ABC, where AB = AC and BC is the base. Assume the vertex A is at the origin (0, 0), the base endpoints B and C are at coordinates (-b, c) and (b, c) respectively.
First, find the midpoint M of BC. The coordinates of M will be the average of the x-coordinates and the y-coordinates of B and C. Thus, M = (0, c).Next, determine the slope of line AM (vertex to midpoint). Since A is at (0, 0) and M is at (0, c), the slope is:AM slope = (c - 0) / (0 - 0) which is undefined, indicating a vertical line.Now, calculate the slope of the base BC with endpoints B(-b, c) and C(b, c). The slope of BC is:
BC slope = (c - c) / (b + b) = 0 / 2b = 0, indicating a horizontal line.Since the slope of AM is vertical (undefined) and the slope of BC is horizontal (0), lines AM and BC are perpendicular by definition.The segment that joins the vertex angle of an isosceles triangle to the midpoint of its base is perpendicular to the base.

Answers
The equation that relates the mass of the object m and the length of the spring s is s = 0.3m, based on the given information that a 30-gram object stretches the spring 9 centimeters.
The direct variation between the mass of an object and the length of a spring can be described by the equation:
s = k × m, where s is the spring length, m is the mass of the object, and k is the constant of proportionality.
For a 30-gram object stretching the spring to 9 centimeters, the constant k can be found using:
k = s/m, which is k = 9 cm / 30 g, so k = 0.3 cm/g.
Therefore, the equation that relates the mass of the object m and the length of the spring s is s = 0.3m.

Emily is training for a 10K race. On day one, she runs for 20 minutes. On day two, she runs for 30 minutes. On day three, she runs for 40 minutes. If this pattern continues, how many minutes will she run on day 8?
Answers
Answer:
90 minutes
Step-by-step explanation:
Given that On day one, she runs for 20 minutes. On day two, she runs for 30 minutes. On day three, she runs for 40 minutes, this pattern may be presented as an arithmetic sequence shown below
20, 30, 40 ...
For an arithmetic sequence whose first term is a, and a common difference d, the nth term of the sequence may be given as
Tn = a + (n - 1)d
Hence the first term is 20, the common difference d is 10
On the 8th day, the 8th term
T8 = 20 + (8 - 1) 10
= 20 + 70
= 90 minutes
Final answer:
Emily will run for 90 minutes on day 8, calculated by applying the formula for the n-th term of an arithmetic sequence with a first term of 20 minutes and a common difference of 10 minutes.
Explanation:
Emily is training for a 10K race with a pattern of increasing her running time by 10 minutes each day. On day one, she runs for 20 minutes, on day two for 30 minutes, and on day three for 40 minutes. To calculate how many minutes she will run on day 8, we can observe this as an arithmetic sequence where the common difference is 10 minutes.
Using the formula for the nth term of an arithmetic sequence, which is an = a1 + (n-1)d, where:
a1 is the first termd is the common differencen is the term numberWe know that a1 is 20 minutes, d is 10 minutes, and n is 8 because we are looking for the time on day 8.
Therefore, a8 = 20 + (8-1)
10 = 20 + 70 = 90 minutes.
So, on day 8, Emily will run for 90 minutes.
