Answer:

The answer is 256 [tex]in^{3}[/tex].

Step-by-step explanation:

To solve for the volume of the sphere, start by using the sphere volume formula, which is V = [tex]\frac{4}{3} \pi r^{3}[/tex]. However, in this formula, 3 will be used instead of    ([tex]\pi[/tex]).

Next, plug in the information given from the problem, and the formula will look like V = [tex]\frac{4}{3}[/tex] (3) ([tex]4 in^{3}[/tex]).    

Then, solve the equation, and the answer will be 256 [tex]in^{3}[/tex].

Answer:

k=1.1

Step-by-step explanation:

-1.1k=-1.21

divide by -1.1 on both sides to cancel out the -1.1 in front of k so you just have k

Answer:

k = 1.1

Step-by-step explanation:

-1.1k= -1.21

Divide each side by -1.1

-1.1k/-1.1 = -1.21/-1.1

k = 1.1

Answer:

x²+4x+4x+16

x(X+4)+4(X+4)

(x+4)(X+4)=0

Answer:

x = - 4

Step-by-step explanation:

= − ± 2 − 4 / 2

Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

x2+8x+16=0

= 1

= 8

= 1 6

x= − 8 ± 8 ^2 − 4× 1 × 1 6  /  2×   1

= − 8 ± 64 − 4×   1   ×1 6  / 2× 1

= − 8± 6 4 − 6 4 /   2×  1

x = -8 / 2× 1  

x = -8 / 2

x = -4

Answer:

200 actual miles

Step-by-step explanation:

Find the actual distance by multiplying 50 by 4, since there are 50 miles in 1 inch.

50(4)

= 200

So, there are 200 actual miles between the two cities.

Answer:

x = 2, y = -1.

Step-by-step explanation:

2x - 5y = 9

3x + 4y = 2

Multiply first equation by -3 and the second by 2:

-6x + 15y = -27

6x + 8y = 4            Adding the 2 equations:

23y = -23

y = -1.

Now substitute this value for y in the first equation:

2x - 5(-1) = 9

2x = 9 +5(-1)

2x = 9 - 5

2x = 4

x = 2.

Answer:

The answer is 57

Step-by-step explanation:

25 X 3 = 75

75 - 18 = 57

Good luck :)

Answer:

First multiply 25 by 3 which gives you 75.

You then take 75 minus the amount of pink lemonade she has already sold, which is 18.

Your answer should be 57.

So Sofie has 57 cups of pink lemonade left for sale.

Answer:

60 miles per hour

Step-by-step explanation:

since the car goes 240 miles in 4 hours, you would divide 240 by 4 to see how fast the car goes for 1 hour.

=========================================

Work Shown:

a = 300 = first term

r = 60/300 = 0.2 = common ratio

We multiply each term by 0.2, aka 1/5, to get the next term.

Since -1 < r < 1 is true, we can use the infinite geometric sum formula below

S = a/(1-r)

S = 300/(1-0.2)

S = 300/0.8

S = 375

----------

As a sort of "check", we can add up partial sums like so

and so on. The idea is that each time we add on a new term, we should be getting closer and closer to 375. I put "check" in quotation marks because it's probably not the rigorous of checks possible. But it may give a good idea of what's going on.

----------

Side note: If the common ratio r was either r < -1 or r > 1, then the terms we add on would get larger and larger. This would mean we don't approach a single finite value with the infinite sum.

Answer:

[tex]\text{D. 36.64}[/tex]

Step-by-step explanation:

The Law of Sines is given by [tex]\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}[/tex] and works for any triangle.

Therefore, we have the proportion:

[tex]\frac{c}{\sin 41.5^{\circ}}=\frac{37}{\sin 42^{\circ}},\\\\c=\frac{37\sin 41.5^{\circ}}{\sin 42^{\circ}}=36.6399945706\approx \boxed{36.64}[/tex]

Answer:

  a = 9 meters

Step-by-step explanation:

The perimeter is the sum of the side lengths:

  28 m = a + 2m + a + 8m

  18 m = 2a . . . . . . . . . . . . . . . . subtract 10m, collect terms

  9 m = a . . . . . . . . . . . . . . . divide by 2

The value of a is 9 meters.

Answer:

0.28

Step-by-step explanation:

To know the probability we first need to know the total number of choices for each character in the license plate. Since there are a total of 10 possible numbers (0-9) and 26 letters in the English Alphabet. Then this means that each character has a total of 36 possible choices. Out of these 36 only 10 are numbers, therefore the probability of the first character being a number is

[tex]\frac{10}{36}[/tex] or 0.2777

If we rounded the decimal to the nearest hundredth it would be 0.28

Answer:

The correct answer is 0.28

Answer:

In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object. The area of a figure is the number of unit squares that cover the surface of a closed figure. Area is measured in square units such as square centimteres, square feet, square inches, etc.

Step-by-step explanation:

Answer:

Area is the quantity that expresses the extent of a two-dimensional region, shape, or planar lamina, in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object.

3)1

4)2

5)4

Step-by-step explanation:

recall that,

[tex] \displaystyle {x}^{ - n} = \frac{1}{ {x}^{n} } [/tex]

we want to evaluate [tex]x^{-2}[/tex] for x=-2

to do so substitute the given value of x

[tex] \displaystyle {2}^{ - 2} [/tex]

apply the formula:

[tex] \displaystyle {2}^{ - 2} = \frac{1}{ {2}^{2} } [/tex]

simplify square:

[tex] \displaystyle {2}^{ - 2} = \boxed{\frac{1}{ 4} }[/tex]

likewise substitute the given value of x to x^-1:

[tex] \displaystyle {2}^{ - 1} [/tex]

apply the formula:

[tex] \displaystyle {2}^{ 1} = \frac{1}{ {2}^{1} } [/tex]

[tex] \displaystyle {2}^{ 1} = \boxed{\frac{1}{ {2}^{} } }[/tex]

substitute the value of x

[tex] \displaystyle {2}^{ 0} [/tex]

it's a universal truth that x⁰=1 Thus

[tex] \displaystyle \boxed{1}[/tex]

Substitute the given value of x to x¹ and x² respectively

[tex] \displaystyle {2}^{ 1} \quad \bigg | \quad {2}^{2} [/tex]

simplify:

[tex] \displaystyle \boxed{2} \quad \bigg | \quad \boxed4[/tex]

and we're done!
