The diameter of a sphere with a volume of 397 meter cube to the nearest tenth of a meter is 9.1 meters
Volume of a spherevolume of a sphere = 4 / 3 πr³
where
r = radius of the sphereTherefore,
volume = 397m³
Diameter = radius × 2
Hence,
volume of a sphere = 4 / 3 πr³
volume of a sphere = 4 / 3 × 3.14 × r³
397 = 12.56 / 3 r³
cross multiply
397 × 3 = 12.56 r³
1191 = 12.56 r³
divide both sides by 12.56
r³ = 1191 / 12.56
r = ∛94.8248407643
r = 4.56009658
Hence,
diameter = 4.56009658 × 2 = 9.12 = 9.1 meters

y- blank
Answer:
y: 13, 22, 25, 28
ordered pairs: (3, 13) (6, 22) (7, 25) (8, 28)
Step-by-step explanation:
Given:
function: y = 3x + 4values of x: -3, 6, 7, 8To find the y-values, substitute the x-values into the function and solve.
when x = 3
y = 3(3) + 4
= 9 + 4
= 13
when x = 6
y = 3(6) + 4
= 18 + 4
= 22
when x = 7
y = 3(7) + 4
= 21 + 4
= 25
when x = 8
y = 3(8) + 4
= 24 + 4
= 28
Therefore, the ordered pairs are; (3, 13) (6, 22) (7, 25) (8, 28)

a. 0.905
b. 0.917
c. 0.999
d.0.976
Answer:
a) 0.905 (3 dp)
Step-by-step explanation:
Binomial distribution X ~ B(n, p)
where n is the the number of trials and p is the probability of success
Binomial formula:
[tex]P(X=x)=\left(\left\begin{array}{cc}n\\x\end{array}\right) \cdot p^x \cdot (1-p)^{n-x}[/tex]
Given: X ~ B(100, 0.001)
Therefore, n = 100 and p = 0.001
Substituting these values into the binomial formula and solving for x = 0:
[tex]\implies P(X=0)=\dfrac{100!}{0!100!} \cdot 0.001^0 \cdot (1-0.001)^{100-0}[/tex]
[tex]\implies P(X=0)=1 \cdot 1 \cdot 0.999^{100}[/tex]
[tex]\implies P(X=0)=0.9047921471...[/tex]
[tex]\implies P(X=0)=0.905 \ \sf(3 \ dp)[/tex]

If you have
[tex]3^{n-1} *\frac{n(n+1)}{2} = 20412[/tex]
whats the process for solving n?
Answer:
Step-by-step explanation:
3^(n-1) * (n(n+1)/2 = 20412
The n(n +1)/2 is a factorial which is defined for integers so we are looking for a whole number solution.
We could draw a graph manually or using software and get the solution where the graph cuts the x axis.
Also we could find the prime factors of 20412:
20412 = 2^2 * 3^6 * 7
and try substituting 2, 3 and 7 into the equation
Using this method we see that one solution is n = 7.
I could have tried n = 7 first because 3^n-1 = 3^6!!
What does n equal? Please help!
Answer:
x=0
Step-by-step explanation:

A triangular garden has an area of 144 ft² If the base is 8 ft long, what is the height? 9 ft 18 ft 36 ft 48 ft.
Answer:
36 feet
Step-by-step explanation:
Hello!
Recall that the formula for the area of a triangle is [tex]\frac12b*h[/tex]
That means the equations is 144 = 0.5(8 * h)
Solve:
144 = 0.5(8) * h144 = 4 * h144 = 4h36 = hThe height is 36, but since the units are feet, it is 36 feet.
In the question it is given that a triangular garden has an area of 144 ft² and measure of its base is 8ft. So we would be simply using the formula of calculating the area of rectangle.
[tex]\boxed{\sf{Area \: of \: triangle \: = \: \dfrac{1}{2} \times l \times b }} \: \red\bigstar[/tex]Here,
l is length b is breadthTo calculate :
Height of the triangle? (i.e. length)We have :
length (l) = 8ft Area (A) = 144 ft²Putting the values in formula :
[tex] \implies \: \sf{144 = \: \dfrac{1}{2} \times l \times 8 } \\ \\ \implies \: \sf{144 = \: \dfrac{1}{ \cancel2} \times l \times \cancel8 } \\ \\ \implies \: \sf{144 = \: \dfrac{1}{1} \times l \times 4 } \\ \\ \implies \: \sf{144 = \: l \times 4 } \\ \\ \implies \: \sf{ l \: = \: \dfrac{144}{4} } \\ \\ \implies \: \sf{ l \: = \: \cancel\dfrac{144}{4} } \\ \\ \implies \: \sf{ l \: = \: \dfrac{72}{2} } \\ \\ \implies \: \sf{ l \: = \: \cancel\dfrac{72}{2} } \\ \\ \implies \: \sf{ l \: = \: \dfrac{36}{1} } \\ \\ \implies \: \red{\underline{\underline{\bf{ l \: = \: 36 }}}}[/tex]
Henceforth,
Height is of 36 ft.Which of the following represents the area of a rectangle whose length is 3x + 5 and whose width is x - 2? (1 point)
Answer:
A = 3x² - x - 10
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = length × width , then
A = (3x + 5)(x - 2)
each term in the second factor is multiplied by each term in the first factor.
A = 3x(x - 2) + 5(x - 2) ← distribute parenthesis
= 3x² - 6x + 5x - 10 ← collect like terms
= 3x² - x - 10
Answer:
A = 3x² - x - 10
Step-by-step explanation:
A = length × width
A = (3x + 5)(x - 2)
A = 3x(x - 2) + 5(x - 2)
A = 3x² - 6x + 5x - 10
A = 3x² - x - 10

your answer.
-
A=d
a(" --
(1 + i)" – 1
i
A the future value of the account after n periods
d the amount invested at the end of each period
i the interest rate per period
n = the number of periods
Based on the amount that London deposited every month and the number of years involved, London would have $57,515.16.
How much would London have in 11 years?The amount that London deposits every month is an annuity because it is a fixed amount.
The value in 11 years is therefore the future value of an annuity which can be found as:
= Amount x ( (1 + rate) ^ number of periods - 1) / rate
The number of periods is:
= 11 years x 12 months
= 132 months
Future value is:
= 320 x ( ( 1 + 0.45%)¹³² - 1) / 0.45%
= $57,515.16

3(x-5)^2-17=-5
Answer:
x = 3 , x = 7
Step-by-step explanation:
3(x - 5)² - 17 = - 5 ( add 17 to both sides )
3(x - 5)² = 12 ( divide both sides by 3 )
(x - 5)² = 4 ( take square root of both sides )
x - 5 = ± [tex]\sqrt{4}[/tex] = ± 2 ( add 5 to both sides )
x = 5 ± 2
then
x = 5 - 2 = 3
x = 5 + 2 = 7
the chef mixed a seasoning that costs $3 per ounce with a seasoning that costs $1.75 per ounce to create a 24-ounce mixture that costs $2 per ounce. how many ounces of the $3 per ounce seasoning did he use?
Answer:
4.8 ounces
Step-by-step explanation:
X= number of ounces for the $3.00 mixture of seasoning
$3.00/OZ + $1.75/ OZ = $2.00/ OZ We are adding the seasonings together to produce the 24 OZ mixture
X + 24-X = 24OZ To get the missing term we will subtract what we have from X
100 [(3.00)(X) + (1.75)(24-X)] = [(2.00)(24)] 100 to get rid of the decimals multiply both sides by 100
(300)(X) + (175)(24-X) = (200)(24) Multiply on each side, removing the parenthesis
300X + 4,200 - 175x = 4,800 Get all of the X's on one side of the equation remember to change the sign of 4,200
300X - 175X = 4,800 - 4,200 Combine Like Terms
125X = 600 Get X alone
125 125 To get X, we will divide both sides by 125
X = 4.8 OZ
The chef used 4.8 ounces of the $3.00 seasoning
Find the perimeter and area of a regular hexagon with side lengths of 8 and an apothem of 9.
The perimeter and area of a regular hexagon with side length of 8 and apothem of 9 are 48 units and 216 units² respectively.
What is a regular hexagon?A regular hexagon is a polygon with 6 sides and the angles are congruent.
The perimeter of the hexagon is the sum of the whole sides. Therefore,
side length = 8 units
apothem = 9 units
perimeter = 8 × 6 = 48 cm
The area of the hexagon can be calculated as follows:
area = 1 / 2 pa
where
p =perimeter
a = apothem
Therefore,
area = 1 / 2 × 48 × 9
