What is the volume of a hemisphere with a diameter of 8.6 ft, rounded to the nearest tenth of a cubic foot? \text{Volume of a Sphere:}
Answer:
volume V = 166.519071 ft^3
Step-by-step explanation:
radius r = 4.3 ft
base circumference C = 27.0176968 ft
volume V = 166.519071 ft^3
curved surface area A = 116.176096 ft^2
base surface area B = 58.0880482 ft^2
total surface area K = 174.264144 ft^2
In Terms of Pi π
base circumference C = 8.6 π ft
volume V = 53.0046667 π ft^3
curved surface area A = 36.98 π ft^2
base surface area B = 18.49 π ft^2
total surface area K = 55.47 π ft^2
Volume of a hemisphere:
V = (2/3)πr^3

An extended family is trying to plan a reunion and needs to find out where everyone would like to attend. Jill decides to send an e-mail to one person from each of the different families to get their opinion. She then follows up with those that she doesn't hear from. Is this a good way to collect data?
Answer:
I don't think so. Because what if that specific family member never checks their email. I think a good way would have been to email more than one or every person in that family (now since its extended you might not know everyone so just as many as you know of)
is a negative number to the seventh power negative
7 is an odd number since it can't be divided evenly by 2.
A negative number taken to an odd power will always be negative.
For example, -1⁵ is -1 because 5 is an odd number.

Convert the equation to Standard Form.
y=2(x+1)^(2) −4
Answer:
(-8x2-16x-8)
Step-by-step explanation:
y= (2x + 2)^2 (2 - 4)
y= (2x + 2)(2x + 2)(2 - 4)
y= −82−16−8

At a movie night,1/4 of the persons were boys,5/8 were girls and the rest were adults.If there were 56 more girls than adults how many persons were in total?
Given:
Number of boys = [tex]\dfrac{1}{4}[/tex] of the total persons.
Number of girls = [tex]\dfrac{5}{8}[/tex] of the total persons.
Remaining persons are adults.
There were 56 more girls than adults.
To find:
The number of total persons.
Solution:
Let x be the number of total persons. Then,
Number of boys = [tex]\dfrac{1}{4}x[/tex]
Number of girls = [tex]\dfrac{5}{8}x[/tex]
Number of adults = Total persons - Boys - Girls
= [tex]x-\dfrac{1}{4}x-\dfrac{5}{8}x[/tex]
= [tex]\dfrac{8x-2x-5x}{8}[/tex]
= [tex]\dfrac{x}{8}[/tex]
There were 56 more girls than adults.
Girls = Adults + 56
[tex]\dfrac{5}{8}x=\dfrac{x}{8}+56[/tex]
[tex]\dfrac{5}{8}x-\dfrac{x}{8}=56[/tex]
[tex]\dfrac{4}{8}x=56[/tex]
[tex]\dfrac{1}{2}x=56[/tex]
Multiply both sides by 2.
[tex]x=112[/tex]
Therefore, the total number of persons is 112.

Write a function with a slope of 4 that includes the point (−1, 3)
Answer:
I'm not sure but I think the answer is
F(x)=3
The function with a slope of 4 can be written as F(x) = 4x + 7.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the slope is 4 and the line is passing through the point (-1,3).
The y-intercept will be calculated as,
y = mx + c
3 = 4 x -1 + c
c = 7
The equation can be written as,
y = mx + c
y= 4x + 7

If y varies directly with x and y = 84 when x = 12, find y when x = 11.
Answer:
y= 77
Step-by-step explanation:
Write down the equation for direct proportion.
y= kx, where k is a constant.
Find the value of k.
When x= 12, y= 84,
84= k(12)
12k= 84
k= 84 ÷12
k= 7
Substitute the value of k into the equation.
y= 7x
When x=11,
y= 7(11)
y= 77
Solve. Round to the nearest hundredth.

Hope this helps ^-^
help me now i need this question right away
Answer:
It will be 120°
It because if you matched those two points you will have two angles of 90° degree inside that square and in the triangle at the above 120-90= 30 degrees for both angles and since that all angles of the triangle are equal 180 then 180-(30+30)=120°.

brian, tim and kenny got paid a total of $240 for mowing neighborhood lawns . They split the money in the ratio of 5:9:10 . how much money did each boy make . PLEAEEEE SHOW THE work i’m really struggling rn
Answer:
$50 for Brian
$90 for Tim
$100 for Kenny
Step-by-step explanation:
Let 5x = amt for Brian
9x = amt for tim
10x = amt for ken
5x + 9x + 10x = 240
24x = 240
x = 10
5x = 5(10) = $50 for Brian
9x = 9(10) = $90 for Tim
10x = 10(10) = $100 for Kenny
Answer:
Step-by-step explanation:
5x + 9x + 10x = $240
x = $10
Brian got 5x = $50
Tim got 9x = $90
Kenny got 10x = $100
