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.

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°.

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.

The value of the mixed expression 2 x (12) x 3/2 will be 36.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is 2 x (12) x 3/2. the value of the expression will be calculated as below:-

E = 2 x (12) x 3/2.

E = 12 x 3

E = 36

Therefore, the value of the mixed expression 2 x (12) x 3/2 will be 36.

Replacing with data:

Z = (7.9 - 8.15)/0.07

Z = -3.57

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

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).

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).

I guess the answer should be 177.8 cm.

The measurement of 5 feet 10 inches to centimeters​ is 175 centimeters.

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.

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.

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:

[tex]D = \frac{k}{1291} kg/m^3[/tex]

Answer:

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)
