How do I solve this, pretty urgent please.

Andreas93 [3]

Answer:

Step-by-step explanation:

<u>Substitute:</u>

$x^{0.5} = y$

<u>Then the expression becomes:</u>

$(\dfrac{1+y^3}{1-y+y^2}-y) \dfrac{1-y^2}{1-y} -y=\\$
$(\dfrac{(1+y)(1-y+y^2)}{1-y+y^2}-y) \dfrac{(1-y)(1+y)}{1-y} -y=$
$(1+y-y)(1+y)-y=$
$1(1+y)-y=$
$1+y-y=$
1

The result is 1 regardless the value of x other than 1.

Find the surface area of the right rectangular prisim

Vlad [161]

Answer:

46 units^2

Step-by-step explanation:

The formula for surface area of a rectangular prism is

SA = 2(lw +lh+wh) where l is length, w is width and h is height

SA = 2 (2.5* 4+ 2.5*2 + 4*2)

= 2 (10+5+8)

= 2( 23)

= 46 units^2

Camila owns a food truck that sells tacos and burritos. She only has enough supplies to make 120 tacos or burritos. She sells ea

LekaFEV [45]

The inequalities is given by x + y ≤ 120, 4.75x + 7.5y > 690 and y ≥ 80. A possible solution is selling 10 tacos and 100 burritos

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.

Let x represent the number of tacos and y represent the number of burritos sold, hence:

x + y ≤ 120 (1)

Also:

4.75x + 7.5y > 690 (2)

and:

y ≥ 80 (3)

The inequalities is given by x + y ≤ 120, 4.75x + 7.5y > 690 and y ≥ 80. A possible solution is selling 10 tacos and 100 burritos

Sean bought 68 3/4 inches of rope . How many 15-inches ropes can he make from it

choli [55]

Length of rope bought by Sean = 68 3/4 inches
   = 275/4 inches
Then
The number of 15 inch rope that can be made by Sean = (275/4)/15
   = 275/(4 * 15)
   = 275/60
   = 4.58
So we can see from the above deduction that Sean can make 4 complete 15 inches ropes and there will be 0.58 inches of rope excess. <span>I hope the procedure and the method of solving is absolutely clear to you. This is the easiest way to get to the solution for such problems.</span>
