The top of the gumball machine on the left is a sphere with a diameter of 20 inches. When the machine is full it can hold 3500 gumballs, leaving 40% of the space in the machine empty. What is the approximate radius of each gumball? Round to the nearest hundredth and use 3.14 for Pi
Answer:
0.555 in
Step-by-step explanation:
The first thing we must do is calculate the volume of the machine, the volume of a wait is:
v = (4/3) * pi * (r ^ 3)
we know that the diameter is twice the radius, therefore:
r = d / 2 = 20/2
r = 10, replacing:
v = (4/3) * 3.14 * (10 ^ 3)
v = 4186.66 in ^ 3
Now, we know that by leaving 40% of space in the machine there are 3,500 chewing gums, therefore, 60% of that volume is chewing gum.
4186.66 * 0.6 = 2512
to calculate the volume of a chewing gum:
3500 * v = 2512
v = 2512/3500
v = 0.7177 in ^ 2 is the volume of a single chewing gum
if we solve the sphere formula for r, we are left with:
r ^ 3 = v * (3/4) / pi
replacing
r ^ 3 = 0.7177 * (3/4) /3.14
r ^ 3 = 0.1714
r = 0.1714 ^ (1/3)
r = 0.555
the radius of each gum is 0.555 in

(solve triangles using the law of sines)
Answer:
[tex]B=51[/tex]°
Step-by-step explanation:
Use the Law of Sines as follows:
[tex]\frac{sinC}{c} =\frac{sinB}{b}[/tex]
Insert the appropriate values:
[tex]\frac{sin100}{14} =\frac{sinB}{11}[/tex]
Isolate B. Multiply both sides by 11:
[tex]11*(\frac{sin100}{14} )=11*(\frac{sinB}{11})\\\\\frac{11*sin100}{14} =sinB\\\\sinB=\frac{11*sin100}{14}[/tex]
Use the inverse:
[tex]B=sin^{-1}(\frac{11*sin100}{14})[/tex]
Insert the equation into a calculator and round to the nearest degree:
[tex]B=50.7\\\\B=51[/tex]
Angle B is 51°.

Given the equation, (x - h)2 + (y - k)2 =r2, what are the coordinates of the center?
The coordinates of the center are ( , )
Answer:
(h, k).
Step-by-step explanation:
This is the standard form of the equation of a circle
The coordinates of the center are (h, k)
The radius is r.
The coordinates of the center are (h, k).
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
The equation is,
⇒ (x - h)² + (y - k)² = r²
Now, We know that;
The standard form of the equation of circle is,
⇒ (x - h)² + (y - k)² = r²
Where, (h, k) is coordinates of the center and r is the radius of the circle.
Hence, By comparing, we get;
The coordinates of the center are (h, k).

so we add the number that it grew to the size it was before.
Answer: 1.85 + x = 5.30
Step-by-step explanation: If we know that Ethan planted a tree that was 1.85 meters tall from the start and several years later it's 5.30 meters tall, we know that something must have been added to the 1.85 in order to get 5.30 meters tall. Since we don't know what that value is, we can use x.
X is an example of a variable. A variable is just a letter that represents any number so in this case, it represents how much the tree has grown over a time period of several years.
So we can write this as 1.85 + x = 1.30.
Which expression is a cube root of -2?
A. Cubed root of 2 (cos(90°) + isin(90°))
B. Cubed root of 2 (cos(120°) + isin(120°))
C.cubed root of 2 (cos(60°) + isin(60°)).
D. Cubed root of 2 (cos(260°) + isin(260°))
If you raise a cube root of -2 to the third power, the resulting number will have a congruent argument. We have
-2 = 2(cos 180º + i sin 180º)
Pick a number from the 4 given options, and raise it to the third power using DeMoivre's theorem. For example,
[tex]\left(\sqrt[3]{2}\left(\cos90^\circ+i\sin90^\circ\right)\right)^3=2\left(\cos(3\cdot90^\circ)+i\sin(3\cdot90^\circ)\right)=2(\cos270^\circ+i\sin270^\circ)=-2i[/tex]
so the first option is not a cube root of -2 because the argument 270º is not congruent to 180º. Similarly, the second and fourth options are also not cube roots of -2.
On the other hand,
[tex]\left(\sqrt[3]{2}(\cos60^\circ+i\sin60^\circ)\right)^3=2(\cos180^\circ+i\sin180^\circ)[/tex]
so the third option is a cube root of -2.

(5 points) Part B: The area of a rectangle is (9a2 − 16b2) square units. Determine the dimensions of the rectangle by factoring the area expression completely. Show your work. (5 points)
Answer:
(2a -5)²(3a -4b)(3a +4b)Step-by-step explanation:
There are a couple of factored forms that are used here:
(a +b)² = a² +2ab +b² . . . . the sign of "2ab" will match the sign of b
a² -b² = (a -b)(a +b)
__
Part A:
Since this trinomial is known to be a perfect square, you can find the binomial(s) by looking at the roots of the first and last terms.
√(4a²) = 2a
√25 = 5
The factoring is ...
4a² -20a +25 = (2a -5)²
__
Part B:
This is the difference of perfect squares, so the terms of the factors can be found as in the previous part.
√(9a²) = 3a
√(16b²) = 4b
Using the above factored form, we have ...
9a² -16b² = (3a -4b)(3a +4b)

PLEASE HELP! The density of atmosphere (measured in kilograms/meter) on a certain planet is found to decrease as altitude increases (as measured from
the planet's surface). What type of relationship exists between the altitude and the atmospheric density, and what would the atmospheric
density be at an altitude of 1.291 kilometers?
Answer:
The relationship that exist between the altitude and the atmospheric density is an inverse relationship.
[tex]D = \frac{k}{1291} kg/m^3[/tex]
Step-by-step explanation:
since the density of the atmosphere decreases as the altitude increases, the relationship that exist between the altitude and the atmospheric density is an inverse relationship. This can be represented by:
[tex]D = \frac{k}{H}[/tex], where k is the constant, H is the altitude in meters and D is the atmospheric density in kg/m.³
When the altitude is 1.291 km, i.e H = 1.291 km = 1291 m,the atmospheric density D is:

Jackson at the collectibles fair. He has exactly $8 and will purchase a collectible from a vendor for $5. What percent of his money will Jackson spend on the purchase?
Answer:
62.5%
Step-by-step explanation:
Total money with Jackson = $8
Money spent for buying collectible = $5
__________________________________________________
Percentage of any number A with respect to another number B is calculated by multiplying fraction A/B with 100
Numerically A as percentage of b will be expressed as (A/B)100 %
It means that if there are 100 items instead of B item then what will be the value of A.
______________________________________________________
Percentage of money spent = (Money spent for buying collectible /Total money with Jackson)
Substituting the total money and money spent for buying collectible
we have
Percentage of money spent = 5/8 * 100 = 0.625*100 = 62.5%
Thus, 62.5% percent of his money will Jackson spend on the purchase of collectible.

1 foot = 12 inches. 1 inch = 2.5 centimetres. Change 5 feet 10 inches to centimetres
I guess the answer should be 177.8 cm.
The measurement of 5 feet 10 inches to centimeters is 175 centimeters.
What is Unit of Measurement?Units of measurement are defines ad the definite magnitude of a physical quantity. It is used to find a number that shows the amount of something.
Here we have to convert the units of measurement feet and inches to centimeters.
We have,
1 foot = 12 inches and 1 inch = 2.5 centimeters
We have to change 5 feet 10 inches to centimeters.
1 foot = 12 inches
⇒ 5 feet = 12 × 5 inches
= 60 inches
So, 5 feet 10 inches = 60 inches + 10 inches
= 70 inches
1 inch = 2.5 centimeters
70 inches = 70 × 2.5 centimeters
= 175 centimeters
Hence we got 5 feet 10 inches as 175 centimeters.
