A globe has a diameter of 14 inches. Find the volume of the globe. Round your answer to the nearest tenth.

Answers

Answer:

1436.8 in³ (nearest tenth)

Step-by-step explanation:

A globe is in the shape of a sphere.

[tex]volume \: of \: sphere = \frac{4}{3} π {r}^{3} [/tex]

Diameter= 2 ×radius

radius of globe

= 14 ÷2

= 7 inches

Volume of globe

[tex] = \frac{4}{3} π {(7}^{3} ) \\ = 1436.8 \: in^{3} \\ (nearest \: tenth)[/tex]

Step-by-step explanation:

We have given that diameter of globe (sphere) is 14 inches,Then it's radius is 14/2 = 7 inches :]

To find the volume of sphere we have to use the given below formula :]

[tex] \boxed {\underline{ \underline{\bigstar\:\: \sf Volume \: of \: sphere = \dfrac{4}{3} \pi r^3 \: \: \bigstar}}} \\ \\ [/tex]

☯ [tex]\underline{\boldsymbol{According\: to \:the\: Question\:now :}} [/tex]

[tex]:\implies \sf Volume \: of \: sphere = \dfrac{4}{3} \times 3.14 \times 7 \times 7 \times 7 \: \: \bigg \lgroup \bf{putting \: \pi = 3.14} \bigg \rgroup \\ \\ [/tex]

[tex]:\implies \sf Volume \: of \: sphere = \dfrac{4}{3} \times 3.14 \times 343 \\ \\ [/tex]

[tex]: \implies \underline{ \boxed{ \sf Volume \: of \: sphere = 1436.0267 \: cubic \: inches}} \\ [/tex]

what is the smallest two digit positive integer such that the product of its two digits is one-half the integer

Answers

Let x be the tens and y be the ones digits.

The product of the number is then: 10x + y

The product is 1/2, so you need to multiply the product by 2 and the number:

10x + y = 2(x+y)

10x + y = 2x + 2y

Subtract 1 y from both sides

10x = 2x + y

Subtract 2x from

Both sides

8x = y

X has to be 1 , which would make y 8

The product number becomes 18

Since the product is 1/2, multiply by 2:

18 x 2 = 36

3 x 6 = 18

The answer is 36

Solve for f.
Round your answer to 2 decimals.

Step-by-step explanation:

Let's solve your equation step-by-step by isolating f.

9f=12f−2

Step 1: Subtract 12f from both sides.

9f−12f=12f−2−12f

You get:

−3f=−2

Step 2: Divide both sides by -3.

−3f/−3 = −2/−3

You get:

f= 2/3, or f= 0.67

Adams, Greensburg, Middletown, and Waldron are four towns in Indiana on a nearly straight highway. If the highway is represented by a line, the
towns can be represented by four points: A, G, M, and W. Given that M is the midpoint of AW and MG =
MA + GA, determine the
proper order of the four towns.

Answers

Answer:

W, M, A and G

Step-by-step explanation:

The question is not correct, the correct question is Adams, Greensburg, Middletown, and Waldron are four towns in Indiana on a nearly straight highway. If the highway is represented by a line, the  towns can be represented by four points: A, G, M, and W. Given that MG + WM = WG and MA = MG - AG determine the  proper order of the four towns.

Answer: The line segment addition postulate states that for a line segment AC with point B which lines on AC, then this equation holds:

AB + BC = BC

Given that MG + WM = WG, this means that point M lies between the segment WG.

Also, MA = MG - AG

MA + AG = MG, hence point A lies between segment MG

Therefore the order of the points is W, M, A and G

How to find if it is a function or not:
The set of ordered pairs (Z,A) where z is the zip code, and A is the street address.​

Answers

Answer: It is not a function.

Step-by-step explanation:

A function is something that "eats" an input and transforms it into an output.

We write them as y = f(x)

Where x is the input, and y is the output.

Now, a function has an important rule, for each input x, the function can only "transform it" (or map it) into only one possible output.

This means that, for example, if we have, for x = x1.

And a single

f(x1) = y1

f(x1) = y2

where y1 and y2 are different values.

Then this is not a function, because it is mapping the value x1 into two different outputs.

In this case, we would have:

f(Z) = A.

So Z is the input, but we know that a ZIP code works for an entire city, and in a given city we have lots of different street addresses, then for a single value of the input, Z, we have a lot of possible values of the output.

This means taht the set (Z, A) can not represent a function.

Encuentren dos números cuyo cociente sea -1 y que la resta del primero menos el segundo sea -3/2

Answers

Answer:

[tex]\dfrac{3}{4}\ \text{and}\ \dfrac{-3}{4}[/tex]

Step-by-step explanation:

Find two numbers whose quotient is -1 and the subtraction of the first minus the second is -3/2

Let two numbers are x and y. When they are divided the quotient is -1. So,

[tex]\dfrac{x}{y}=-1[/tex]

It can also be written as :

x = -y ....(1)

The subtraction of first minus the second is -3/2 .

[tex]x-y=\dfrac{-3}{2}\ .....(2)[/tex]

Use equation (1) in (2),

[tex]-y-y=\dfrac{-3}{2}\\\\-2y=\dfrac{-3}{2}\\\\y=\dfrac{3}{4}[/tex]

From equation (1) : [tex]x=\dfrac{-3}{4}[/tex]

Hence, two numbers are [tex]\dfrac{3}{4}\ \text{and}\ \dfrac{-3}{4}[/tex].
