Airplanes use radar (radio waves) to measure distances.

The plane is at a height of 5200 m. The airport is 10.2 km away.

How far does the plane need to travel before it lands?

a) 11.4 km

b) 10.4 km

c) 5200 km

d) 10.2 km

Answers

Answer:

10.2 km

Step-by-step explanation:

I thought we have to add 5200 m + 10,2 km, but for this result there is no an alternative. So the correct answer must be 10,2 km, if the plane is right above the airport.

D is the answer, hope it helped

mary works for a commission of 12% on all goods she sell for the month if her basic salary is 3000 per month and she sells $2500 worth of goods for a certain month calculate mary's gross salary for that particular month

Answers

Answer:

3300

Step-by-step explanation:

Formula

Gross Salary = Basic + Commission

Givens

Basic = 3000

% = 12%

Solution

Gross = 3000 + 12/100 * 2500

Gross = 3000 + 30000/100

Gross = 3000 + 300

Gross = 3300

Hey there!

The answer is 6:54

The time on the clock shows 6:20, because the hour hand is after the 6, and the minute hand is on the 4 (which we multiply by 5 to get the minutes).

If it takes her 8 minutes to walk to the bus, 10 to pack lunch, and 16 to get dressed, that's a total of 8 + 10 + 16 minutes, or 34 minutes.

So, we add that to the minutes, so 20 + 34 = 54, therefore the time is 6:54 when she arrives.

A bird can lay either white or brown eggs. Three white eggs
and
two brown eggs have a mass of 13 grams, while five white eggs
and four brown eggs have a mass of 24 grams. Find the mass
of a brown egg and of a white egg.

Answers

Answer:

Mass of brown egg = 3.5 grams

Mass of white egg = 2 grams

Step-by-step explanation:

Let

Mass of brown eggs = x

Mass of white eggs = y

3y + 2x = 13 (1)

5y + 4x = 24 (2)

Multiply (1) by 5 and (2) by 3 to eliminate y

15y + 10x = 65 (3)

15y + 12x = 72 (4)

Subtract (3) from (4)

12x - 10x = 72 - 65

2x = 7

x = 7/2

x = 3.5

Substitute x = 3.5 into (1)

3y + 2x = 13 (1)

3y + 2(3.5) = 13

3y + 7 = 13

3y = 13 - 7

3y = 6

y = 6/3

y = 2

Mass of brown egg = 3.5 grams

Mass of white egg = 2 grams

Phil is riding his bike. He rides 25 miles in 2 hours, 37.5 miles in 3 hours, and 50
miles in 4 hours. Find the constant of proportipnality and write an equation to
describe the situation. Let x represent the number of hours.
The equation that describes the relationship is y =

Answers

The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.

The equation is

12.5

Explanation:

To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:

For example

miles

hours

12.5

miles

A direct proportionality will always result in an equation that resembles this:

Answer:

[tex]b = 19[/tex]

Step-by-step explanation:

1) Add 7 to both sides.

[tex]b = 12 + 7[/tex]

2) Simplify 12 + 7 to 19.

[tex]b = 19[/tex]

Therefor the answer is, b = 19.

Answer:

Sample Response

Step-by-step explanation:

Use the inverse operation to isolate the variable. Undo the subtraction of 7 by adding 7 to each side of the equation. – 7 + 7 = 0, and 12 + 7 is 19. The solution is b = 19. Check the solution by substituting 19 for b in the original equation, and then simplify. 19 – 7 is 12 and 12 = 12 is a true statement, so 19 is the solution.
