Suppose an airplane climbs 15 feet for every 40 feet it moves forward. What is the slope of this airplanes ascent?

Goryan [66]

Answer:

3/8

Step-by-step explanation:

Slope is the same as rise over run, or y/x. In this case, rise over run is 15 over 40, or 15/40. Simplified, this is 3/8.

Solve the system of equations using substitution

Sauron [17]

y = −2x + 1

4x + 2y = −1

Replace Y in the second equation with the value of Y in the first one.

4x + 2(-2x +1) = -1

Distributive Property:

4x + -4x + 2 = -1

Combine like terms:

2 = -1 which is not true, so there are no solutions.

Givens

pi = 3.14

d = 3.8

r = d/2

r = 3.8/2 = 1.9

Formula

V = (4/3) * pi * r^3

Solution

V = (4/3) * 3.14 * 1.9^3

V = 4/3 * 3.14 * 6.859

V = 28.7163

crimeas [40]

Answer:

Faisal receives $241

Ahmed receives $482

Walid receives $723

Step-by-step explanation:

I am going to build a system of equations to solve this question.

We have that:

x is the amount that Faysal received.

y is the amount that Ahmed received.

z is the amount that Walid received.

Ahmed, Walid and Faisal made $1446 profit from selling used books.

This means that

$x + y + z = 1446$

Ahmed to receive double amount of Faisal

This means that $y = 2x$

Walid to receive triple amount of Faisal.

This means that $z = 3x$

$x + 2x + 3x = 1446$

$6x = 1446$

$x = \frac{1446}{6}$

$x = 241$

$y = 2x = 2*241 = 482$

$z = 3x = 3*241 = 723$

Faisal receives $241

Ahmed receives $482

Walid receives $723
