Part A.) A planet’s diameter is approximately 27,340,000 meters. What is that number in scientific notation?



Part B.) What is the product of 3.20 × 10–5 and 6.5 × 103?

Answers

Answer:

A = 2.734*10^7,  B = .208

Step-by-step explanation:

A = 2.734*10^7

There are 7 decimal places from 0 to 10 million

B = .208

multiply 3.2 and 6.5, get 20.8, 10^3 * 10^-5 =10^-2

20.8 * 10^-2 = .208

Answer:

Part A)

[tex] 2.734\times 10^{7}\: meters [/tex]

Part B)

[tex] 0.208 [/tex]

Step-by-step explanation:

Part A)

[tex] 27,340,000 \: m = 2.734\times 10^{7}\: m [/tex]

Part B)

[tex] (3.20\times 10^{-5}) (6.5\times 10^3)[/tex]

[tex] =3.20\times 6.5 \times 10^{-5}\times 10^3[/tex]

[tex] =20.8 \times 10^{-5+3}[/tex]

[tex] =20.8 \times 10^{-2}[/tex]

the answer is B 87.5

Let f(t) represent the temperature of a turkey baking in an oven as a function of time t in the oven (in minutes). This means time is the independent variable and temperature of the turkey is the dependent variable. The turkey was in the oven for 360 minutes and then removed. Note that when something is baked in an oven, the temperature of the oven stays constant.

Explain the meaning of each statement in the context of the situation using everyday language. Remember that the input of the function t is the time in the oven and the output f(t) is the temperature of the turkey at that time.

1. f(0) = 50. (8 points)

2. f(120) > f(60). (8 points)

3. f(360) = f(345). (7 points)

4. f(390) < f(360). (7 points)

Answers

Answer:

Step-by-step explanation:

1. f(0) = 50. (8 points)  The beginning temperature of the turkey was 50 degrees.  The '0' represents "beginning."

2. f(120) > f(60). (8 points)  The temperature of the turkey after 120 min (2 hours) is greater than that after 60 minutes (1 hour).

3. f(360) = f(345). (7 points)  The temperature of the turkey is the same after 360 minutes as it is after 345 minutes.

4. f(390) < f(360). (7 points)

The temperature of the turkey drops after 360 minutes (6 hours), because the turkey is taken out of the oven and/or the oven is turned off.

Ten members of Balin’s soccer team ran warm ups for practice. Each member ran the same distance. Their combined distance was StartFraction 5 Over 6 EndFraction of a mile. To find the distance that each member ran, Balin wrote the expression below.

Answers

Answer:

Each member ran (1/12) of a mile.

Step-by-step explanation:

We have 10 members of Balin's soccer team.

Each one of them ran a distance D.

We know that their combined distance was 5/6 of a mile.

And if each one of them ran the same distance D, then the combined distance is ten times D, or :

10*D

and this is equal to 5/6 of a mile, then we get the equation:

10*D = (5/6) of a mile.

We want to solve this for D, so we can divide both sides by 10:

10*D/10 = (5/6)/10 of a mile.

D = (5/10*6) of a mile

D = (5/10)/6 of a mile

D = (1/2)/6 of a mile

D = (1/2*6) of a mile

D = (1/12) of a mile.

This means that each member ran (1/12) of a mile.

Step-by-step explanation:

find the x and y intercepts of the graph -6x + 4y = 32 state your answers as while numbers or as improper fractions in simplest form

Answers

Answer:

x intercept = -5.33

y intercept = 8

Step-by-step explanation:

The given equation is ,

⇒ -6x + 4y = 32 ,

The standard form of the Intercept form is ,

⇒ x/a + y/b = 1 , where

a is x interceptb is y intercept .

• Converting the equation :-

⇒ 2( -3x + 2y ) = 32

⇒ -3x + 2y = 16

⇒ -3x + 2y / 16 = 1

⇒ (-3x)/16 + 2y/16 = 1

⇒ -3x/16 + y/8 = 1

Convert -3x/16 in x/a form

⇒ x/-5.33 + y/8 = 1 .

Therefore ,

x intercept = -5.33 y intercept = 8

Answers

Answer:

1/2

Step-by-step explanation:

To multiply fractions, you multiply numerator with numerator and denominator with denominator:

a/b*c/d=(a*c)/(b*d)

5/6*18/30=(5*18)/(6*30)=90/180=9/18=1/2

Therefore, the answer is 1/2. Looks like your answer of 113/30 either is wrong or the problem was not formatted correctly.

On a given planet, the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 9 kg weighs 63 N . Calculate the mass of another object that weighs 14 N.

Answers

Answer:

The mass is 2 kg.

Step-by-step explanation:

W = kM     where k is a constant so

63 = k*9

k = 7

So: W = 7M

when W = 14:

14 = 7M

M = 2.

What is the area of the shaded region in the given circle in terms of pi and in simplest form?

A) (120pi + 6 sqrt 3) m^2

B) (96pi + 36 sqrt 3) m^2

C) (120pi + 36 sqrt 3) m^2

D) (96pi + 6 sqrt 3) m^2

Answers

Answer:

Area of the shaded portion = (120π + 36√3)sq. m

Step-by-step explanation:

Area of the shaded region = Area of circle - Area of triangle

Given

radius of the circle = 12m

Area of the circle = πr²

Area of the circle  = π(12)²

Area of the circle  = 144π m²

Area of the sector = theta/360 * πr²

Area of the sector =  60/360 * 12²π

Area of the sector = 60/360 * 144π  = 24π

Area of the triangle = 1/2 bh

Area of the triangle = 1/2 (12cos30)(12)

Area of the triangle = 36√3

Area of the shaded portion = (144π - 24π + 36√3)sq. m

Area of the shaded portion = (120π + 36√3)sq. m

Tom is told by his doctor that he needs to lose 15 pounds if Tom now it's 285 pounds then by what percentage should Tom's week decrease

Answers

Answer:

the percentage is 5.56%

Step-by-step explanation:

The computation of the percentage that the tom should decrease is shown below:

As Doctor said tom to reduce 15 pounds

As of now the tom has 285 pounds

So after considering the 15 pounds, it would be

= 285 - 15

= 270 pounds

Now the percentage that should be considered is

= (285 - 270) ÷ (270)

= 5.56%

Hence, the percentage is 5.56%

Answers

Answer:

$16080

Step-by-step explanation:

Given data

Wholesale price = $12,000

Profit = 34%

Let us find 34% of $12,000

=34/100*12000

=0.34*12000

=$4080

Hence the markup price is $4080

And the retail price is

=4080+12000

=$16080
