The volume of the hemisphere with the given value of radius to the nearest tenth is 246.4 cubic foot.
Hemisphere
A hemisphere is gotten when a sphere is cut into two equal halves.
The volume of a hemisphere is expressed as;
V = (2/3)πr³
Where r is the radius and π is pi ( π = 3.14 )
Given the data in the question;
Radius of the hemisphere r = 4.9ftVolume of the hemisphere V = ?To determine the volume of the hemisphere, we substitute our values into the expression above.
V = (2/3)πr³
V = (2/3) × π × (4.9ft)³
V = (2/3) × π × 117.649ft³
V = 246.4ft³
Therefore, the volume of the hemisphere with the given value of radius to the nearest tenth is 246.4 cubic foot.

Two six-sided number cubes are rolled at the same time. What is the probability that the result will have at least one two in it?
(A)7/36
(B)1/5
(C)11/36
(D)1/6
Answer:
1/6
Step-by-step explanation:
There are 12 numbers in total. There is a 2 on each cube so there are two possible chance. 2/12=1/6 2/2=1 and 12/2=6 therefore 2/12=1/6
The solution is, the probability that the result will have at least one two in it is, 1/6.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given that,
Two six-sided number cubes are rolled at the same time.
so, we get,
There are 12 numbers in total.
There is a 2 on each cube so there are two possible chance.
2/12=1/6
2/2=1
and 12/2=6
now, we have,
therefore 2/12=1/6.

1) The product of two numbers is 8. One of the numbers is x. Write an expression for the other number.
2) Fiifi is 3 years older than JoJo. If JoJo is x years old, write an expression for the sum of their ages.
Answer:
1 ) y = 8 / x
2 ) 3 + 2x
Step-by-step explanation:
1 )
One number = x
Let the other number be y.
The product of two numbers is 8,
( x ) ( y ) = 8
xy = 8
y = 8 / x
Expression for the other number is,
y = 8 / x
2 )
JoJo = x years old
Fiifi = ( 3 + x ) years old
Expression for the sum of their ages
= 3 + x + x
= 3 + 2x

Sharon uses 6.3 pints of blue paint and white paint to paint her bedroom walls. 4 5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Given:
Sharon uses 6.3 pints of blue paint and white paint to paint her bedroom walls.
[tex]\dfrac{4}{5}th[/tex] of this amount is blue paint and the rest is white paint.
To find:
The pints of white paint did she use to paint her bedroom walls.
Solution:
We have,
Total paint used = 6.3 pints
Blue paint = [tex]\dfrac{4}{5}th[/tex] of total paint used
= [tex]\dfrac{4}{5}\times 6.3[/tex]
= [tex]5.04[/tex]
White paint = Total paint used - Blue paint
= [tex]6.3-5.04[/tex]
= [tex]1.26[/tex]
Therefore, Sharon uses 1.26 pints of white paint to paint her bedroom walls.

The measure of ABD is (0.18x + 67) degrees and the measure of CBD is (0.07 + 48) degrees. Find the value of X
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]ABD = 0.18x +67[/tex]
[tex]CBD = 0.07x + 48[/tex]
Required
Find x
The question is incomplete as the relationship between ABD and CBD is not stated.
Assume ABD = CBD
The solution is:
[tex]0.18x + 67 = 0.07x + 48[/tex]
Collect like terms
[tex]0.18x - 0.07x= - 67 + 48[/tex]
[tex]0.11x= -19[/tex]
Solve for x
[tex]x = -\frac{19}{0.11}[/tex]
[tex]x = -172.72[/tex]
Assume ABD and CBD are supplementary
The solution is:
[tex]ABD + CBD=180[/tex]
[tex]0.18x + 67 + 0.07x + 48 = 180[/tex]
Collect like terms
[tex]0.18x + 0.07x = - 48 - 67 + 180[/tex]
[tex]0.25x = 65[/tex]
Solve for x
[tex]x = \frac{65}{0.25}[/tex]
[tex]x = 260[/tex]
Assume ABD and CBD are complementary
The solution is:
[tex]ABD + CBD=90[/tex]
[tex]0.18x + 67 + 0.07x + 48 = 90[/tex]
Collect like terms
[tex]0.18x + 0.07x = - 48 - 67 + 90[/tex]
[tex]0.25x = -25[/tex]
Solve for x
[tex]x = \frac{-25}{0.25}[/tex]
[tex]x = -100[/tex]
