8 km + 2300 m +12,000 cm = ?

Answers

Answer:

The result is 10.42 kilometers, or 10,420 meters or 1'042,000 centimeters.

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

8 kilometers plus 2,300 meters plus 12,000 centimeters

2. Let's do the conversions to find the result either in kilometers, meters or even centimeters.

A. In kilometers:

8 kilometers

2,300 meters = 2.3 kilometers

12,000 centimeters = 120 meters = 0.12 kilometers

10.42 kilometers

B. In meters

8 kilometers = 8,000 meters

2,300 meters

12,000 centimeters = 120 meters

10,420 meters

C. In centimeters

8 kilometers = 8,000 meters = 800,000 centimeters

2,300 meters = 230,000 centimeters

12,000 centimeters

1'042,000 centimeters

The final sum is 10,420 meters.

To solve the mathematical problem of adding different units of measurement, we first need to convert everything to the same unit. In this case, let's convert all measurements to meters (m).

Convert 8 kilometers (km) to meters. Since 1 km = 1000 m => 8 km = 8 x 1000 => 8000 m.Convert 2300 meters (m) to meters. This is already in meters, so no conversion is needed and it remains 2300 m.Convert 12,000 centimeters (cm) to meters. Since 1 m = 100 cm, 12,000 cm = 12,000 / 100 = 120 m.

Now, add these values together:

8000 m + 2300 m + 120 m = 10,420 meters

Two angles are a linear pair. One third of the measure of the first plus 12 is equal to the measure of the second. what are the measures of both angles?

Answers

Answer:

Step-by-step explanation:

Let's angle be x and y

Then......

⅓x+12=y......eqn(I)

Since are linear

x+y=180

y=180-x.....eqn(ii)

Substitute the eqns

You get x=126°

From eqn (iii)

You get y=54°

Those are angles

The measures of both angles are 126° and 54°.

What are Linear Pair of Angles?

Linear pair of angles are the pair of angles formed when two lines are intersected at a point forming on a line.

Sum of the measures of angles of linear pair is supplementary.

Given that,

Two angles are a linear pair.

Let x and y be the measures of two angles.

We have,

y = 1/3 x + 12

Sum of the angles is supplementary.

x + y = 180

x + 1/3 x + 12 = 180

4/3 x = 168

x = 126°

y = 180 - 126 = 54°

Hence the angles are 126° and 54°.

9. Wade has 126 inches of 1-inch wide bias tape for a border
on a rectangular banner. If the banner needs to be 48
inches long, what is the maximum width it could be?​

Answers

Answer:

Let 'x' represent the width.

2*48 + 2x = 126

x = 15 in

The maximum width could be 15 inches.

Final answer:

To find the maximum width of the rectangular banner, calculate the total length of bias tape used, subtract it from the available bias tape, and divide the remaining inches by 2. The maximum width of the banner is 15 inches.

Explanation:

Maximum Width Calculation:

Calculate the total length of bias tape used: 48 inches x 2 sides = 96 inches.

Subtract the total length from the available bias tape: 126 - 96 = 30 inches.

Divide the remaining inches by 2 (since there are 2 widths): 30 / 2 = 15 inches.

Find the height of the image after it has been scaled by 80% the following number of times. Explain or show your reasoning

Answers

After 3 times, it reduces to 76.8 mm, and after 6 times, it further reduces to approximately 39.3 mm.

To find the height of the image after it has been scaled by 80% multiple times, we can use the formula for scaling:

[tex]\[ \text{New height} = \text{Original height} \times (\text{Scale factor})^{\text{Number of times scaled}} \][/tex]

Given that the original height is 150 mm and the scale factor is 80% (or 0.8), we can calculate:

a. After being scaled 3 times:

[tex]\[ \text{New height} = 150 \times (0.8)^3 = 150 \times 0.512 = 76.8 \, \text{mm} \][/tex]

b. After being scaled 6 times:

[tex]\[ \text{New height} = 150 \times (0.8)^6 = 150 \times 0.262 \approx 39.3 \, \text{mm} \][/tex]

As the image is scaled down by 80% each time, its height decreases significantly with each iteration.

After 3 times, it reduces to 76.8 mm, and after 6 times, it further reduces to approximately 39.3 mm.

These heights fall within the acceptable range for a U.S. passport photo (25-35 mm).

A pilot is traveling at a height of 30,000 feet above ground she looks down at a angle of depression of 6 and spots runway as measured along the ground how many miles away is she from the runway

Answers

Distance between runway and pilot position along the ground is 285430.9336 feet that is 53.9464 miles.

Solution:

Given that

Height of position of pilot from the ground = 30000 feet

Angle of depression when he looks down at runway = 6o

Need to measure along the ground, distance between runway and pilot that is horizontal distance between runway and pilot.

Consider the figure attached below

D represents position of runway.  

P represents position of pilot.

PG represents height of position of pilot from the ground that means PG = 30000 feet

PH is virtual horizontal line and HPD is angle of depression means ∠ HPD = 6 degree

AS DG and HP are horizontals, so DG is parallel to HP.

=>  ∠ HPD =∠ PDG =  6 degree  [ Alternate interior angle made by transversal PD of two parallel lines ]

We need to calculate DG

Consider right angles triangle PGD right angles at G

[tex]\text {As } \tan x=\frac{\text { Perpendicular }}{\text { Base }}[/tex]

[tex]\tan \angle \mathrm{PDG}=\frac{\mathrm{PG}}{\mathrm{GD}}[/tex]

[tex]\begin{array}{l}{=>\mathrm{GD}=\frac{\mathrm{PG}}{\tan \angle \mathrm{PDG}}} \\\\ {=>\mathrm{GD}=\frac{30000}{\tan 6^{\circ}}=285430.9336}\end{array}[/tex]

As one foot = 0.000189 miles

[tex]=>285430.9336 \text { feet }=285430.9336 \times 0.000189 \text { miles }=53.9464 \text { miles. }[/tex]

Hence distance between runway and pilot position along the ground is 285430.9336 feet that is 53.9464 miles.

Final answer:

To find the distance to the runway, we can use trigonometry and create a right triangle using the pilot's height and the angle of depression. Using the tangent function, we can solve for the distance. The pilot is approximately 58.47 miles away from the runway.

Explanation:

To find the distance to the runway, we can use trigonometry. The angle of depression of 6 degrees tells us that the runway is below the pilot's line of sight. We can create a right triangle with the pilot's height of 30,000 feet as the opposite side and the distance to the runway as the adjacent side. Using the tangent function, we can solve for the distance:

Tan(6) = Opposite/Adjacent

Tan(6) = 30,000/Adjacent

Adjacent = 30,000/Tan(6)

Using a calculator, we find that the pilot is approximately 308,517 feet away from the runway.

To convert this distance to miles, we divide by 5,280 (since there are 5,280 feet in a mile):

308,517/5,280 ≈ 58.47 miles

Therefore, the pilot is approximately 58.47 miles away from the runway.

27 + 38 = 65, however 20 + 70 + 38 = 128. The addition problem for D is a way to solve for 27 + 38, because it is broken up differently than A and C.

5. An $800 deposit for 24
months earned $200 in
interest

Answers

Answer:

The rate of interest applied fro compound interest is 24.5 %  

The rate of interest applied simple interest is 37.5 %

Step-by-step explanation:

Given as :

The Principal amount that is deposited = $ 800

The Time period = 24 months = 2 years

The Interest earn = $ 200

Let the rate of interest = R %

So, The Amount = Principal deposited - interest earn

Or, A = $ 800 - $ 200

∴ Amount = $ 600

From compounded method

Amount = Principal × [tex](1+\dfrac{\textrm rate}{100})^{\textrm Time}[/tex]

Or, $ 600 = $ 200 × [tex](1+\dfrac{\textrm R}{100})^{\textrm 2}[/tex]

Or, [tex]\frac{600}{200}[/tex] = [tex](1+\dfrac{\textrm R}{100})^{\textrm 2}[/tex]

Or, 3 = [tex](1+\dfrac{\textrm R}{100})^{\textrm 2}[/tex]

Or, [tex]3^{\frac{1}{2}}[/tex] = (1 +[tex]\frac{R}{100}[/tex])

Or, 1.245 = (1 +[tex]\frac{R}{100}[/tex])

or, 1.245 - 1 = [tex]\dfrac{R}{100}[/tex]

or, 0.245 × 100 = R

So, the rate is = 24.5 %

Hence The rate of interest applied fro compound interest is 24.5 %  Answer

From Simple Interest method

Simple Interest = [tex]\dfrac{\textrm Principal\times \textrm Rate\times \textrm Time}{100}[/tex]

Or, $ 600 = [tex]\dfrac{\textrm 800\times \textrm R\times \textrm 2}{100}[/tex]

Or,  $ 600 × 100 = $ 800 × R × 2

Or, R = [tex]\frac{60000}{1600}[/tex]

∴ R = 37.5 %

So, The rate is 37.5 %

Hence The rate of interest applied simple interest is 37.5 %Answer

As he went around a curve, he noticed a bear walking toward him. Immediately his pupils dilated, he began to perspire, and his heart accelerated. These changes are most closely related to the function of the:A angulargyrusB hippocampusC parasympathetic nervous systemD sympathetic nervous systemE ventricularsystem When a solid is placed in a container and heat is applied, a phase change occurs. Watch the video and identify which of the following statements are correct. Check all that apply. View Available Hint(s) Check all that apply. The temperature increases while all of a liquid is converted to a gas. When a solid is converted to a liquid, heat is absorbed. The average kinetic energy of the system changes while all of a solid is converted to a liquid. Temperature remains constant while all of a solid is converted to a liquid. When heat is applied to a solid, the molecular motion decreases as the temperature increases. A government collects $700 billion annually in tax revenue. Each year it allocates $70 billion to the justice system and $130 billion for its own administrative costs. What percentage of annual tax revenue is allocated to these two categories of government spending? Danielle has $6.65 worth of change in nickels and dimes. If she has 5 times as many nickels as dimes, how many of each type of coin does she have? An electric motor has an eccentric mass of 10 kg (10% of the total mass) and is set on two identical springs (k=3200 N/m). The motor runs at 1750 rpm, and the mass eccentricity is 100 mm from the center. The springs are mounted 250 mm apart with the motor shaft in the center. Neglect damping and determine the amplitude of vertical vibration. . The trait that would be least useful in a phylogenetic analysis would be one that A) is detectable only in observations of early development. B) involves genetically inherited behaviors. C) is altered easily by small changes in diet. D) can be studied only in museum specimens. E) is heritable but is determined by many genes.

PLZ HELP ASAP I WILL GIVE BRAINLIEST!!!!!!!!!!!!Chemical properties and physical properties are properties that can be measured or observed. They can only be measured or observed when matter undergoes a change to become an entirely different kind of matter true or false Write the answer to this question. Energy is measured in units called joules(J). Suppose a roller coaster car starts with 78,000 J of potential energy. In a few seconds, it converts two-thirds of this energy into kinetic energy. As it takes a curve, the car doubles its kinetic energy. How much mechanical energy does the car now have?
