A twin engine aircraft can fly 960 miles from City A to city B in 3 hours with the wind and make the return trip in 8 hours against the wind. What is the speed of the wind?

The area of the path is 456 square feet

The formula for determining area of a rectangle is given as;

A = lw

Where;

Now, substitute the values into the formula, we have;

Area of the rectangle  = 40 × 70

Area of the rectangle = 2800 square feet    (1)

Bordered fence with a 4 ft path so dimensions 44 ft by 74 ft

Area of rectangular garden with Path = 44 × 74

= 3256 square feet       (2)

Area of the walk = (2) - (1) = 3256 - 2800 = 456 square feet

Answer:

11 pizza rolls

Answer:

11 pizza Rolls and 6

Step-by-step explanation:

Answer:

x = 4

y = 1

Step-by-step explanation:

x + 3y = 7 --> Eq1

4x - y = 15 --> Eq2

Find x in term of y using Eq1

x = 7 - 3y

Substitute x in Eq2

4(7-3y) -y = 15

28 - 12y - y = 15

-12y-y = 15 - 28

-13y = -13

y = -13/-13

y = 1

Find x

x = 7-3(1) = 4

If you have to solve for x first

Find y in term of x using Eq 2

y = 4x - 15

Substitute y in Eq 1

x + 3(4x -15) = 7

x + 12x - 45 = 7

x + 12x = 7 + 45

13x = 52

x = 52/13

x = 4

Find y

y = 4(4) -15 = 16 - 15 = 1

Answer:3/2

The inverse function of the function f(x) = 2x - 4 will be x/2 +2.

What is inverse function?

A function that returns the initial value for which a function has produced output is called an inverse function. If f(x) is a function that produces the value y, then f-1(y), which is the inverse function of y, will produce the value x. Inverse and reciprocal functions should not be confused. The output's original value is returned by the function's inverse, which is represented by the symbol f-1 (x). While the reciprocal of a function is represented by 1/f(x) or f(x)-1

Those that do are referred to as invertible. For a function f: X Y to have an inverse, it must possess the characteristic that there is exactly one x in X such that f(x) = y for every y in Y. This characteristic guarantees the existence of a function g: Y X that has the required connection to f.

f(x) = 2x - 4

y = 2x - 4

So x = y +4 /2

x = y/2 +2

Now to get the inverse of the function  put the x value in y

So [tex]f^{-1}[/tex](x) = x/2 +2

Hence, inverse function will be x/2 +2.

The number of nickels and the number of dimes that Joseph has are 12 and 5 respectively.

An equation of degree one is known as a linear equation.

A linear equation of two variables can be represented by ax + by = c.

Let the no. of nickels be N and no. of dimes be D.

∴ N + D = 17...(i) and 0.05N + 0.1D = 1.45...(ii)

Multiplying (ii) by 100 we get 5N + 10D = 145...(iii)

Now multiply (i) by 5 we get 5N + 5D = 85...(iv)

Now subtracting (iv) from (iii) we get,

5D = 60.

The solid is a prism with a trapezoid base.

volume = (area of base) × height

V = (8 cm + 5 cm)(1/2)(4 cm) × 6 cm

V = 156 cm³

Answer:

A trapezoid is isosceles if and only if its diagonals are congruent. So if we can prove that the bases are parallel and the diagonals are congruent, then we know the quadrilateral is an isosceles trapezoid, as Cool Math accurately states.

Step-by-step explanation:

The true statements are

The side length of the transparent cube is given as

Length = 10 millimetres

The volume of the cube is calculated as

Volume = Length³

The equation of y=x^3 and Vertical compression by a factor of 1/7 ,horizontal shift 8 units to the left, reflection across the x axis

Applying the given transformations, we have:

To have a vertical compression by a factor of 1/7, we need to multiply the function by 1/7. So, we have:

y=1/7x³

We must add 8 to x in order to have a horizontal shift of 8 units to the left. We thus have:
