Answer:
Volume of a sphere is (pi)*(r^2)*(h), where r is raduis, h is height, and pi is 3.14.
Diameter is 24/2 = 12
We just need to plug everything in.

In a camp ,there is enough flour for 300 persons for 42 days.How long will the flour last if 20 more persons join the camp
Answer/Step-by-step explanation:
Direct proportion: If a variable increases then other variable also increases with a constant factor i.e. y = kx
Inverse proportion: if a variable increases then other variable decreases with a constant factor i.e xy = k
Assume that food will last for d days if 20 more persons join the camp.
Understand the fact that for given food number of days food last is inversely proportional to the number of persons hence product of days food lasts and number of persons is constant,
Days x number of persons = constant
Equate the product of 300 persons and 42 days with (300 + 20) person and d days to solve for d.
[tex](300+20) *d=300*42[/tex]
⇒ [tex]d = \frac{12600}{320}[/tex]
⇒ [tex]d =\frac{1260}{32}[/tex]
⇒ [tex]d=\frac{315}{8}[/tex]
⇒ [tex]d=39.375[/tex] [tex]days[/tex] [tex]or[/tex] [tex]39(\frac{3}{8} )days[/tex] [tex]in[/tex] [tex]fraction[/tex]
Hence, if 20 more people Join (320 people ) it will last 39.375 days in decimal or 39 3/8 days in fraction

Do 42 and 43 pleasee
Answer:
42. A
43. C
Step-by-step explanation:
42. The answer is A. This is because we are distributing (multiplying) the 7.2 to each number in the parentheses.
43. If Hal ran 4.5 laps, then he ran...
0.65 mil (since each lap is 0.65 miles)* 4.5 (laps) = C. 2.925 miles.
Answer:
42. A, distributive property tells us how to solve expressions in the form of a(b + c).
43. 0.65 miles x 4.5 laps = 2.925, C
17 is what percent of 68?
Answer:
25%
17 is what percent of 68?
Its 25%
17/68*100
= (17*100)/68
= 1700/68 = 25
Answer:
25%
Step-by-step explanation:
Question : 17 is what percent of 68?
Answer :
To solve this let the unknown percentage be x .
Let us solve now.
68 × x% = 17
68 × [tex]\frac{x}{100}[/tex] = 17
And now let us find the percentage by making x as the subject.
[tex]x=\frac{17*100}{68}[/tex]
[tex]x = \frac{1700}{68}[/tex]
[tex]x =25[/tex]
Therefore, the percentage is 25%

which of the following polynomials has a graph with odd symmetry? a. 7x^4+13x^3-11 b. 5x^7+4x^6+3x^5+x c.13x^5 -1/2x^3+7x+3 d. 8x^5+7x^3-5x
Answer:
D) [tex]f(x)=8x^5+7x^3-5x[/tex]
Step-by-step explanation:
A function is odd if its graph is symmetric to the origin, which we can check this if [tex]f(-x)=-f(x)[/tex] is true:
Option A
[tex]f(x)=7x^4+13x^3-11\\\\f(-x)=7(-x)^4+13(-x)^3-11\\\\f(-x)=7x^4-13x^3-11[/tex]
Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry
Option B
[tex]f(x)=5x^7+4x^6+3x^5+x\\\\f(-x)=5(-x)^7+4(-x)^6+3(-x)^5+x\\\\f(-x)=-5x^7+4x^6-3x^5+x[/tex]
Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry
Option C
[tex]f(x)=13x^5-\frac{1}{2}x^3+7x+3\\\\f(-x)=13(-x)^5-\frac{1}{2}(-x)^4+7(-x)+3\\ \\f(-x)=-13x^5-\frac{1}{2}x^4-7x+3[/tex]
Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry
Option D
[tex]f(x)=8x^5+7x^3-5x\\\\f(-x)=8(-x)^5+7(-x)^3-5(-x)\\\\f(-x)=-8x^5-7x^3+5x[/tex]
Since [tex]f(-x)=-f(x)[/tex], then the function DOES have odd symmetry. You can also see that the function is odd because every term has an odd exponent.

You and your friend leave your houses at the same time to meet at a restaurant. The distance (in miles) your friend
is from the restaurant is given by y = -40% + 200, where I is the number of hours since your friend left home.
You live 100 miles from the restaurant and arrive at the same time as your friend. Write a linear equation that
represents your distance from the restaurant
Answer:
When x=0 the friend is 200 miles from the restaurant and at x=5 the friend reaches the restaurant. When x=0 you are 100 miles from the restaurant, so 100 is the y intercept, and when x=5 you reach the restaurant so 5 is the x intercept. We have y=mx+100 and y=0 when x=5, so 0=5m+100 therefore m=-20 and the equation is y=-20x+100.
A balloon containing 0. 040 mol of a gas with a volume of 5. 0 mL was expanded to 1. 0 L. Which equation should you use to find the amount of gas added? V subscript 2 equals StartFraction V subscript 1 n subscript 2 over n subscript 1 EndFraction. N subscript 2 equals StartFraction V subscript 2 n subscript 1 over V subscript 1 EndFraction. N subscript 2 equals StartFraction V subscript 1 n subscript 1 over V subscript 2 EndFraction.
Answer:
n2=v2n1/v1
Or B
Step-by-step explanation:
P, R, and T are constant, then the volume is directly proportional to the mole. Then the correct option is A.
What is an ideal gas equation?An ideal gas is a theoretical composed of a set of randomly moving gas particles that interacts only through elastic collision.
Given
A balloon containing 0.040 mol of a gas with a volume of 5.0 mL was expanded to 1.0 L.
[tex] \rm V_1 = 5 \ mL\\ V_2 = 1000 \ mL\\ n_1 = 0.040 \ mol [/tex]
We know the equation of the ideal gas.
[tex] \rm PV = nRT [/tex]
where P, R, and T are the constant, then
[tex] P \propto n[/tex]
Then we have
[tex] \rm \dfrac{V_2}{V_1} = \dfrac{n_2}{n_1} \\\\ V_2 = n_2 *\dfrac{V_1}{n_1} [/tex]
Thus, the correct option is A.

The diameter of a circle field is 40m and that of another 96m . find the diameter of the circular field whose area is equal to the sum of the area of two fields
Answer :
According to the Question
Diameter of a circle field is 40m and that of another 96m .
We have to find the diameter of the circle whose area is equal to the sum of the area of given two circular fields.
Radius of field whose diameter is 40 m
→ r = 40/2 = 20m
Radius of field whose diameter is 96 m
→ r' = 96/2 = 48m
Now, calculating the diameter of Larger circular field.
Let the radius of larger field be R m .
Now, according to the given statement
Sum of Area of given two circular fields = Area of larger field
➠ πr² + πr'² = πR²
➠ π ( r² + r'²) = π R²
➠ 20² + 48² = R²
➠ 400 + 2304 = R²
➠ 2704 = R²
➠ √2704 = R
➠ 52 = R
Therefore, Diameter = 2 × R = 2×52 = 104 m
So, the diameter of Larger circular field is 104 m .
Answer:
Diameter of the circular field=40 m[tex]r = \displaystyle{ \frac{40 \: m}{2}} [/tex][tex]r=20 m[/tex]Diameter of another circular field=[tex]96 m[/tex]r=[tex]\displaystyle{\frac{96 m}{2}}[/tex]r=48 mArea of circular field(2)=[tex]πr^2[/tex]
=[tex]π×(20)^2[/tex]
=[tex]400π[/tex]
Area of circular field(2)=[tex]πr^2[/tex]
=[tex]π×(48)^2[/tex]
=[tex]2304π[/tex]
The sum of the area of the two fields=[tex]400π+2304π[/tex]=[tex]2704π[/tex]Let the radius of circular field that is formed so be r meter(m).
Now,
[tex] \cancel\pi {r}^{2} = 2704 \cancel\pi[/tex]
[tex] {r}^{2} = 2704[/tex]
[tex]r = \sqrt{2704} [/tex]
[tex]r = 52 \: m[/tex]
Area of the circular field whose area is equal to the areas of two fields,Diameter=[tex]2r[/tex]
Diameter=[tex]2×52[/tex]
Diameter=[tex]104 m[/tex]
