I need some help finding the volume of a sphere with a diameter of 18.6cm. Help would be greatly appreciated!
Answers
Answer:
[tex]V=3367.57\ cm^3[/tex]
Step-by-step explanation:
The diameter of a sphere, d = 18.6 cm
Radius, r = 9.3 cm
We need to find the volume of the sphere. The formula for the volume of a sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3\\\\=\dfrac{4}{3}\times 3.14\times (9.3)^3\\\\=3367.57\ cm^3[/tex]
So, the volume of the sphere is equal to [tex]3367.57\ cm^3[/tex].

A seventh-grade teacher asks her students a survey question. Which questions are appropriate for the teacher to ask her population? Select three options.
Answers
Answer:
The questions that are appropriate for the teacher to ask her population are:
How many hours of sleep do you get per night?
On average, how long does it take you to complete your homework?
What time do you leave for school in the morning?
Step-by-step explanation:
The survey is conducted among the seventh grade students so the valid question their teacher would have asked them is:
How many hours of sleep do you get per night?
On average, how long does it take you to complete your homework?
What time do you leave for school in the morning?
while the other two questions are invalid as it the students are young and they are not legal to vote.
also it is not necessary that they would arrive to school by car. Please mark the brainliest!

Answer: [tex]7,5.66,39^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]IJ=9\\\angle I=51^{\circ}[/tex]
from figure, we can write
[tex]\Rightarrow \sin 51^{\circ}=\dfrac{HJ}{9}\\\\\Rightarrow HJ=9\sin 51^{\circ}=6.99\approx 7[/tex]
[tex]\Rightarrow \cos 51^{\circ}=\dfrac{HI}{9}\\\Rightarrow HI=9\cos 51^{\circ}\\\Rightarrow HI=5.66[/tex]
In right angle trianle, the sum of the remaining two angles is [tex]90^{\circ}[/tex]
[tex]\therefore 51^{\circ}+\angle J=90^{\circ}\\\Rightarrow \angle J=90^{\circ}-51^{\circ}\\\Rightarrow \angle J=39^{\circ}[/tex]
Calculate the surface area of an open cylinder measuring 35cm in diameter and 60cm high.
Answers
Answer:
6598.2 in^2
Step-by-step explanation:
Given data
Diameter= 35in
Radius= d/2= 35/2= 17.5in
Height = 60cm
The expression for the curve surface area of a cylinder is
CSA=2πrh
substitute
CSA= 2*3.142*17.5*60
CSA= 6598.2 in^2
Hence the CSA is 6598.2 in^2

A ball is thrown into the air with an upward velocity of 40 ft/s. Its height h in feet after t seconds is given by the function \large h=-16t^2+40t. What is the ball's maximum height?
Answers
Answer:
[tex]h=25[/tex]
Step-by-step explanation:
From the question we are told that:
Velocity [tex]v=40fts[/tex]
The height h function
[tex]\large h=-16t^2+40t[/tex]
Generally time t is mathematically given by
[tex]h'=-32t+40[/tex]
[tex]-32t+40=0[/tex]
[tex]t=\frac{40}{32}[/tex]
[tex]t=1.25[/tex]
Therefore the ball's maximum height is given as
[tex]\large h=-16(1.25)^2+40(1.25)[/tex]
[tex]\large h=-16(1.25)^2+40(1.25)[/tex]
[tex]h=25[/tex]
if each box represents 1 miles, what is the shortest distance from the school to the skate park.
Answers
The shortest distance between two points is a straight line.
Use the distance formula for points.
In the diagram, we are given two points:
(4,2) and (-3,0).
Let d = distance between the two points.
d = sqrt{(-3 -4)^2 + (0-2)^2}
d = sqrt{(-7)^2 + (-2)^2}
d = sqrt{49 + 4}
d = sqrt{53}
d = 2.2360679775
d = 2.2 miles

find the slope of line AB From the Given figures
please help me and solve him
Answers
Answer:
slope of AB = 0
Step-by-step explanation:
The slope of the x- axis OX = 0
Since AB is parallel to the x- axis and parallel lines have equal slopes, then
slope of AB = 0
Since, the line AB is parallel to X - axes, so every point on the the line AB will have equal Y - coordinates.
lets take it as Y ( y - coordinate is same )
slope :

Answers
The long sides are 5 more than the short base (4x-2) hence each long side is (4x-2)+5 which is simplified to 4x+3.
Keep the perimeter as a hint because it is the total of all the sides, this gives x.
Make the equation
4x+3+4x+3+4x-2 = 64
Simplify
12x+4=64
x=60/12
x=5
The length of one long side is (4*5+4)=24
I hope it’s correct because I’m not sure if they saying that both the sides are 5 inches longer or each of the longer sides are 5 inches longer. It would make a difference.
Hopefully this helped

Answer: -5/12
Step-by-step explanation:
Data: 3/12-1/6-1/4-1/4=x
Step one, Find the common demoninator of the fractions
3/12-1/6-1/4-1/4 = 3/12-2/12-3/12-3/12
Reason: You can't subtract fractions that don't have the same denominatory so by finding the common demoninator you allow the problem to be solved.
Step two, Subtract
3/12-2/12= 1/12-3/12=-2/12-3/12=-5/12
Reason: You subtract fractions(With the same denominator) like normal numbers but you keep the denominator the same. When subtracted, the end result is -5/12 since subtracting a bigger number from a smaller number creates a negative.
Answer: -5/12

In a group of 32 pupils, 3 play the flute only. 13 play the piano only. 10 play neither instrument. A student is selected at random. What is the probability the student plays both instruments?
Answers
Answer:
18.75%
Step-by-step explanation:
Given that
There is a group of 32 pupils
3 play the flute only
13 play the piano only
And, 10 play neither instrument
We need to find out the probability the student plays both instruments
So
= (32 - 13 - 10 - 3) ÷ 32
= 6 ÷ 32
= 0.1875
= 18.75%
Answer:
6/32 or 3/16
Step-by-step explanation:
13 add 10 add 3 = 26
32-26=6
the total amount of children is 32 so the number is 6/32
you can then simplify it to 3/16
