10. A sphere has a volume of 7,234.56 units?. Using 3.14
for pi, find the radius of the sphere. Record your answer
on the grid.
The radius of the sphere has a volume of 7,234.56 units^3 is 1728 units.
We have the sphere has a volume of 7,234.56units^3
V=7,234.56units^3
What is the formula for the volume of a sphere?
[tex]V=(4/3)(pi)(r^3)[/tex]
Where r is the radius.
Solving this for r^3, we get
[tex]r^3=\frac{V}{(4/3)(pi)}[/tex]
[tex]r^3=\frac{V}{(4/3)(3.14)}[/tex]
[tex]r^3=\frac{7,234.56}{4.19}[/tex]
[tex]r=1728[/tex]
Therefore we get the radius of the sphere is r = 1728 units

The area of a square in square feet is represented by z² + 8z + 16.
Find an expression for a side length of
the square.
Find the perimeter of the square when z=12.
Answer:
Side length: z + 4
Perimeter: 64
Step-by-step explanation:
Hello!
Since the area of a square is the square of the sde length,
using the special binomial product formula: (a+b)² = a² + 2ab + b²:
z² + 8z + 16(z + 4)²The side length of the square is (z+4)².
The perimeter is 4(z + 4), where z is 12:
4(12 + 4)4(16)64The side length is z + 4, the perimeter is 64

You are buying bags of flour and bags of sugar for a bakery. You must buy three times as many bags of sugar as there is bags of flour. Also, you are on a budget of $720. Of flour costs $6 per bag and sugar costs $4 per bag, how many bags of flour and how many bags of sugar can you buy
The number of bags of flour would be 40.
And, the number of bags of sugar would be 120.
Given that,
You must buy three times as many bags of sugar as there are bags of flour.
And, you are on a budget of $720. Flour costs $6 per bag and sugar costs $4 per bag.
Let us assume that,
The number of bags of flour = x
And, the number of bags of sugar = y
Hence, we get;
y = 3x .. (i)
And, 6x + 4y = 720 .. (ii)
Substitute x = 3y in (ii);
6x + 4 (3x) = 720
6x + 12x = 720
18x = 720
x = 720/18
x = 40
From (i);
y = 3 × 40
y = 120
Thus, The number of bags of flour = 40
And, the number of bags of sugar = 120

A map use the scale 3/4 of an inch to represent 3 miles .if the actual distance between two cities is25 miles ,then what is the length on the map
3/4 inch
3 miles
to find:the length of the map
solution:Based on the given conditions, write:
x= 34/ 4 · 25/ 3
Write as a single fraction:
x= 3 × 25/ 4/ 3
Divide a fraction by multiplying its reciprocal:
x= 3 x 25/ 4 × 1/ 3
Write as a single fraction:
x= 3 x 25/ 4 × 3
Reduce fraction to the lowest term by canceling 25 the greatest common factor:
x= 25/4
therefore,the length of the map is 25/ 4.

Answer:
Future amount = 48(1 + 0.316074)^12
0.31607412Step-by-step explanation:
You want the exponential equation that can be used to find the number of bacteria in a colony after 12 days if it starts with 48 bacteria and triples in 4 days.
Exponential functionThe exponential function can be written in the form ...
future amount = a·b^(t/p)
where 'a' is the initial amount, 'b' is the growth factor in period p.
The problem statement tells you the initial amount is 48, and the factor by which the amount grows is a factor of 3 in 4 days. This lets you write the function as ...
future amount = 48·3^(t/4) . . . . . where t is in days.
RearrangementThis equation can be rearranged so the only exponent is t:
future amount = 48·(3^(1/4))^t = 48·1.316074^t
future amount = 48·(1 +0.316074)^t
Then the amount in 12 days is ...
future amount = 48·(1 +0.316074)^12
The numbers that go in the boxes are 0.316074 and 12.
__
Additional comment
Working from our original equation, we would compute the number after 12 days to be ...
future value = 48·(3)^(12/4)
Putting the growth factor in "1 +" form, this could be ...
future value = 48·(1 +2)^3
and your box numbers would be 2 and 3. We doubt your answer checker will accept this version of the equation.
Either way, the number of bacteria after 12 days is 1296.
If you use 3^(1/4) -1 as the growth rate in the first box, you need to report it to at least 5 significant digits in order for the future value to come out right. We have shown the value with 6 significant figures.

Answer:
x = 9, y = 3
Step-by-step explanation:
-2x-2y=-24 (EQ 1)
-3x-2y=-33 (EQ 2)
Combining terms we means we either add or subtract the equations in order to eliminate a x or y terms. Simply choose a equation and change it to it's opposite (ex. -3 becomes 3.)
Let's try swapping EQ 1
2x + 2y = 24
(Simply add similar variables and numbers like you would a addition problem.)
-3x-2y=-33
-x = -9
x = 9
Now plug that into one of your equations to get y.
-2(9) -2y = -24
-18 -2y = -24
(Add 18 to both sides.)
-2y = -6
y = 3

Find the equation of a circle given the coordinates of the diameter: (-10,-4) (2,6)
Answer:
(x + 4)^2 + (y - 1)^2 = 61.
Step-by-step explanation:
We need to find the square of the radius and the coordinates of the center.
Center = (-10 + 2)/2 , (-4 + 6)/2
= (-4, 1).
Length of the diameter
= √((-10-2)^2 + (-4-6)^2)
= √(144 + 100)
=√244
So the radius = √244/2
and r^2 = 244/4 = 61,
So the equation of this circle is:
(x - (-4)^2 + (y - 1)^2 = 61
(x + 4)^2 + (y - 1)^2 = 61.
(x + 4)²+ (y - 1)² = 61 is the equation of a circle given the coordinates of the diameter: (-10,-4) (2,6)
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Given coordinates of the diameter of circle are (-10,-4) and (2,6)
Diameter=√(x₂-x₁)²+(y₂-y₁)²
x₂=2,x₁=-10, y₁=-4, y₂=6
Diameter=√(2-(-10))²+(6-(-4))²
=√(12)²+(10)²
=√144+100
=√244
We know that Radius=Diameter/2
R=√244/2
Squaring both sides
R²=244/4
R²=61
So the equation of this circle is:
(x - (-4)² + (y - 1)² = 61
(x + 4)²+ (y - 1)² = 61.
Hence (x + 4)²+ (y - 1)² = 61 is the equation of a circle given the coordinates of the diameter: (-10,-4) (2,6)

What is probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1,
We should consider sequences of three digits, where each digit is either 0 or 1. A sequence has three places .
where each place has two possibilities, i.e., 0 or 1, so, for the multiplication rule
we know that the sample space will have (2)(2)(2) = 8 sample points.
Specifically, the sample space is
S = {111, 110, 101, 011, 100, 010, 001, 000},
There are three sequences with exactly one 0.
Therefore the probability that a sequence will contain exactly one 0 is 3/8.

The volume of a sphere is 4,500π cubic yards. What is the radius of the sphere?
Answer:
15Step-by-step explanation:
In the question it is given that the volume of a sphere is 4,500π cubic yards. And we have to find the radius.
We know that,
4/3πr³ = Volume of a sphereNow, Substituting the values in the fomulae :
⇒ 4/3πr³ = 4500π
Cancelling π from both sides :
⇒ 4/3r³ = 4500
⇒ 4r³ = 4500 × 3
⇒ 4r³ = 13500
⇒ r³ = 13500/4
⇒ r³ = 3375
Taking cube root on both sides we get :
⇒ r = 15
Therefore,
The radius of the sphere is 15 yardsAnswer:
15 yardsStep-by-step explanation:
In this question we have provided volume of sphere that is 4500π cubic yards . And we are asked to find the radius of the sphere .
We know that ,
[tex] \qquad \: \frak{Volume_{(Sphere)} = \dfrac{4}{3}\pi r {}^{3} } \quad \bigstar[/tex]
Where ,
r refers to radius of circleSolution : -
As in the question it is given that volume of sphere is 4500π . So equation it with volume formula :
[tex] \dashrightarrow \: \qquad \: \dfrac{4}{3} \pi r {}^{3} = 4500\pi[/tex]
Step 1 : Cancelling π as they are present on both sides :
[tex]\dashrightarrow \: \qquad \: \dfrac{4}{3} \cancel{\pi }r {}^{3} = 4500 \cancel{\pi}[/tex]
We get ,
[tex]\dashrightarrow \: \qquad \: \dfrac{4}{3} r {}^{3} = 4500[/tex]
Step 2 : Multiplying with 3/4 on both sides :
[tex]\dashrightarrow \: \qquad \: \dfrac{ \cancel{4}}{ \cancel{ 3}} r {}^{ 3} \times \dfrac{ \cancel{3}}{ \cancel{4}} = \cancel{ 4500} \times \dfrac{3}{ \cancel{4} }[/tex]
On further calculations, We get :
[tex]\dashrightarrow \: \qquad \: r {}^{3} = 1125 \times 3[/tex]
[tex]\dashrightarrow \: \qquad \:r {}^{3} = 3375[/tex]
Step 3 : Applying cube root on both sides :
[tex]\dashrightarrow \: \qquad \: \sqrt[3]{r {}^{3} } = \sqrt[3]{3375} [/tex]
We get :
[tex]\dashrightarrow \: \qquad \: \purple{\underline{\boxed{\frak{r = 15 \: yards}}}}[/tex]
