Recall that the volume of a sphere is given by the formula V = 4/3pi to the 3rd
1. Here is a sphere with radius 4 feet. What is the volume of the sphere? Express your answer in
terms of pi.
2. A spherical balloon has a diameter of 4 feet. Approximate how many cubic feet of air this
balloon holds. Use 3.14 as an approximation for it, and give a numerical answer
9514 1404 393
Answer:
1. (256/3)π ft³
2. 33.49 ft³
Step-by-step explanation:
1. Put 4 ft into the formula where r is, then simplify.
V = (4/3)π(4 ft)³ = (256/3)π ft³
__
2. The radius is half the diameter, so is 2 ft. Put that in the formula, along with the value for π, and do the arithmetic.
V = (4/3)(3.14)(2 ft)³ ≈ 33.49 ft³
A man goes into a store and says, “If you give me as much money as I have with me now, I will spend $10 in your store.” The store owner agrees, and the man spends the money.
He goes into a second store and again says, “If you give me as much money as I have with me now, I will spend $10 in your store.” Again, the owner agrees, and the man spends the money.
In a third store, he repeats his proposition. The proprietor agrees, and the man spends the money.
At this point, the man has no money left. How much money did he have to begin with?
Answer:
$8.75
Step-by-step explanation:
Let x = the amount the man originally had
The man has $x and says "if you give me $x, I will spend $10."
y = amount he has after 1st proposition = x + x - 10 = 2x - 10
He repeats this procedure, now with $2x-10 in his pocket...
z = amount he has after 2nd proposition = (2x - 10) + (2x - 10) - 10 = 4x - 30
He repeats this procedure, now with $4x-30 in his pocket...but this time he is left with zero dollars...
r = amount he has after 3rd proposition = (4x-30) + (4x-30) - 10 = 8x-70 = 0
8x - 70 = 0,
x = $8.75
Multiply.
(2x + 4)(2x-4)

what is 25+t
identify
Step-by-step explanation:
We have been investigating whether alloantigen-specific CD4(+)25+ regulatory T cells can be identified for use in treating graft-versus-host disease. CD150, which is upregulated on the surface of all activated T lymphocytes, was identified as a candidate marker for alloantigen-activated CD4(+)25+ regulatory T cells by gene chip analysis. Freshly isolated CD4(+)25+ cells had only low cell-surface expression of CD150, comparable to that of CD4(+)25- T cells. Increased CD150 expression was observed on all T cells after coculture with allogeneic stimulator cells. When purified CD4(+)25+ cells were precultured with allogeneic stimulator cells, then sorted into CD150+ and CD150- subsets, allosuppressive activity was contained primarily in the CD150+ fraction. These cells also suppressed the proliferation of alloantigen-activated autologous T cells, and they could be expanded in vitro without loss of their suppressive capacity. These results suggest that CD150 can be used as a marker for the identification of purified alloantigen-activated CD4(+)25+ regulatory T cells.
What is the area of a square with side lengths of 3/5 units?
To find the area of a square, multiply the side length by itself, also known as sqaring the side length.We must solve 3/5 x 3/5.3/5 x 3/5 = 0.36The units we'll use is because units are the unt we're given, and it is squared because it is the area of a shape.

find an expression for the nth term in the sequence: 35,32,29,26,23
Answer:
32-3n
Step-by-step explanation:
The formula for the nth term of a sequence is ' a+(n-1)d ' where a is the first term and d is the difference.
Here, a is 35 and d is -3.
a+(n+1)d
35+(n+1)(-3)

On a hiking trail map, the distance from mountain peak A to mountain peak B is 12.3 inches. The actual distance is about 1,000 miles. What is the distance on the same map from river A to river B if the actual distance is about 100 miles?
Answer:
The distance of the rivers on the map is of 1.23 inches.
Step-by-step explanation:
We use proportions to solve this question, by a rule of three.
We have that:
If the actual distance is of 1000 miles, the distance on the map is of 12.3 inches. If the actual distance is 100 miles, what will be the distance on the map?
1000 miles - 12.3 inches
100 miles - x
Applying cross multiplication
[tex]1000x = 12.3*100[/tex]
[tex]1000x = 1230[/tex]
[tex]x = \frac{1230}{1000}[/tex]
[tex]x = 1.23[/tex]
The distance of the rivers on the map is of 1.23 inches.
