A plane flies 455 miles with the wind in the same time that it takes to fly 400 miles against the wind. If the wind is blowing at a speed of 12mph, whats the speed of the plane in still ai

Answers

Answer 1

Answer:

186.55 mph

Step-by-step explanation:

Let the speed of the plane be s

The speed of the plane in the same direction is

s + 12

The speed of the plane against wind is

s - 12

Time = distance/speed

455/(s + 12) = 400/(s - 12)

Solving for s

400(s + 12) = 455(s - 12)400s + 400*12 = 455s - 455*12455s - 400s = (400 + 455)*1255s = 10260s = 10260/55s = 186.55 mph

Find two consecutive odd numbers such that the sum of the larger number and twice the smaller number is 27 less then foir times the smaller number

Answers

Answer:

           29 and 31      

Step-by-step explanation:

x      - some integer

2x+1      - an odd integer (the smaller one)

2x+1+2=2x+3       - the next odd integer consecutive to 2x+1  (the larger)

2×(2x+1)       - twice the smaller number

2x+3+2•(2x+1)     -the sum of the larger number and twice the smaller number

4•(2x+1)      - four times the smaller number

4•(2x+1)-27     - 27 less then four times the smaller number

2x + 3 + 2•(2x + 1) = 4•(2x + 1) - 27

2x + 3 + 4x + 2 = 8x + 4 - 27

            6x + 5  =  8x - 23

                  -5            -5

              6x  =  8x - 28

             -8x       -8x

            -2x  =  - 28

          ÷(-2)      ÷(-2)

              x  = 14

2x+1 = 2•14 + 1 = 29

2x+3 = 2•14 + 3 = 31

Step-by-step explanation:

Jim received notice from his employer that the equation to calculate his salary was changing. Currently he makes $300 per week plus 4% commission on sales. The new equation will be $450 plus 2% commission on sales. Which equation shows the amount in sales he will need for his salary to be the same?

Answers

Answer:

Sales= $750

Step-by-step explanation:

let sale be x

and his salary be y

y=300+0.4x----------1 the old equation

y=450+0.2x----------2 the new equation

for his salary to be the same

equation 1 and 2 must be equal hence

300+0.4x=450+0.2x

solving for x we have

300-450+0.4x-0.2x=0

-150+0.2x=0

0.2x=150

x=150/0.2

x=$750

An emerald pendant was marked up 150% from an original cost of $488. Last Friday, Cameron bought the emerald pendant and paid an additional 5% in sale tax. What was his total cost?

Answers

Given parameters:

Mark up percentage  = 150%

Original cost = $488

Sales tax = 5%

Unknown:

His total cost  = ?

Solution:

Marking up a good is the amount a sell adds to a product which makes its selling price usually for a profit.

 Since the emerald was marked up by 150%;

   New cost  = (1 + 1.5) x $488 = $1220

Now, the additional tax was 5%;

   Tax = [tex]\frac{5}{100}[/tex] x 1220 = $61

So, the total cost = New cost + tax  = $1220 + $61 = $1281

About how many times as large is Jupiter's mass compared to Earth's mass? Justify your answer.

Answers

Answer:

Earth is 85.71 times heavier than moonJupiter is 333.33 times heavier than Earth

Step-by-step explanation:

Given

The mass of Earth is about 6 x 10^24 kilograms = eThe mass of the moon is about  7 x 10^ 22 kilograms = mThe mass of Jupiter is about 2 x 10^27 kilograms = j

The difference in mass

e/m = 6 x 10^24 / 7 x 10^ 22 = 600/7 = 85.71

Earth is 85.71 times heavier than moon

j/e = 2 x 10^27 / 6 x 10^24 = 2000/6 = 333.33

Jupiter is 333.33 times heavier than Earth

There is 3/8 of A PIZZA IN ONE BOX AND 1/4 OF A PIZZA IN ANOTHER BOX HOW MUCH DO YOU HAVE ALTOGETHER

Answers

Answer:

5/8

Step-by-step explanation:

I believe this should be fraction addition (?)

8, 4: 8 = 3/8 + 2/8

You have a total of (5/8)th part of a complete pizza.

What is a mathematical function, equation and expression?                function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.

Given is that you have 3/8 of a pizza in one box and 1/4 in another box.

Assume that the total pizza you have is denoted by [x].

[x] = (3/8 + 1/4) of a pizza

[x] = (3 + 2)/8 of a pizza

[x] = 5/8 of a pizza

Therefore, you have a total of (5/8)th part of a complete pizza.

What is linear regression?

Linear regression analysis is used to predict the value of a variable based on the value of another variable. The variable you want to predict is called the dependent variable. The variable you are using to predict the other variable's value is called the independent variable.

Given, The arm span and foot length were measured (in centimeters) for each of the 19 students in a statistics class and displayed in the scatterplot.

let "FL" be the foot length and "AS" be the Arm span.

Slope = Δy/Δx = ΔFL/ΔAS

ΔFL/ΔAS = 0.186

ΔFL = ΔAS* 0.186

thus an increase in AS by 1 cm will lead to an increase in FL by 0.186cm

Therefore,  the slope of the least-squares regression line means for each additional centimeter C) arm span, foot length is predicted to increase by about 0.186 cm.

You add 4 drops of food coloring to 2 cups of white frosting and get the orange frosting above. Francisco wants his frosting to be the same color as yours, but he has 5 cups of white frosting. He doesn't know how many drops of orange food coloring to add.

Answers

Answer:

Francisco will add 10 drops of food coloring to 5 cups of white frosting and get the orange frosting

Step-by-step explanation:

4 drops of food coloring to 2 cups of white frosting and get the orange frosting.

He has 5 cups of white frosting. He doesn't know how many drops of orange food coloring to add

Let x = drops of food coloring he will add

Drops of food coloring : cups of white frosting

4 : 2 = x : 5

4 / 2 = x / 5

Cross multiplication

4 * 5 = 2 * x

20 = 2x

Divide both sides by 2

x = 20 / 2

= 10

x = 10 drops of food coloring

Therefore, Francisco will add 10 drops of food coloring to 5 cups of white frosting and get the orange frosting
