Q3. Stefan has 4 1/2 cups of oats. He uses 3 1/4 cups to make granola bars for
AleksAgata [21]

Answer:

Days can Stefan feed

Coco with the oats he has left is 5 days

Step-by-step explanation:

Total Oats = 4 1/2 cups

He uses 3 1/4 cups to make granola bars for

a camping trip

Remaining oats after making granola bars = Total oats - oats used for granola bars

= 4 1/2 - 3 1/4

.= 9/2 - 13/4

= 18-13/4

= 5/4 cups

Remaining oats after making granola bars is 5/4 cups

Coco needs 1/4 of a cup of oats each day, how many days can Stefan feed

Coco with the oats he has left?

Days can Stefan feed

Coco with the oats he has left = Remaining oats / 1/4 cups

= 5/4 cups ÷ 1/4 cups

= 5/4 × 4/1

= 20/4

= 5 days

Days can Stefan feed

Coco with the oats he has left is 5 days

Translate the statement into an algebraic expression or equation.
Alexandra [31]

We want to translate the given statement into an algebraic expression.

The expression is:

d = 0.45*L

---------------------------------

When we have a discount of an X% on a given value V, that discount will be:

D = (X%/100%)*V.

Here we have:

<em>"A </em><em>discount</em><em> of a 45% on the list price L"</em>

The discount will be given by:

d = (45%/100%)*L = 0.45*L

d = 0.45*L

This is the expression we wanted to get.

Can someone explain the steps for how do solve this?! I can’t get it right
Ulleksa [173]

Answer:

x = 50

m∠D = 150°

m∠F = 30°

Step-by-step explanation:

  • supplementary angles are two angles whose sum is 180°

∠D + ∠F = 180°

3x + x - 20 = 180

3x + x = 180 + 20

4x = 200

x = 200/4

x = 50

D = 3*50 = 150

∠D = 150°

F = 50 - 20 = 30

∠F = 30°

Q(a+1) - 2q(a) if q(x) = x²+3x+4​
siniylev [52]

q(x) =  {x}^{2} + 3x + 4

_________________________________

Step(1)

To find q(a) we just need to put a instead of x in q(x) function.

Let's do it...

q(a) =  {a}^{2} + 3a + 4

Multiply sides by -2 :

- 2q(a) =  - 2( {a}^{2} + 3a + 4)

- 2q(a) =  - 2 {a}^{2} - 6a - 8

_________________________________

Step (2)

To find q(a+1) we just need to put a+1 instead of x in q(x) function.

Let's do it...

q(a + 1) =  ({a + 1})^{2} + 3(a + 1) + 4 \\

q(a + 1) =  {a}^{2} + 2a + 1 + 3a + 3 + 4 \\

q(a + 1) =  {a}^{2} + 5a + 8

_________________________________

Step (3)

q(a + 1) - 2q(a) =

{a}^{2} + 5a + 8 - 2 {a}^{2} - 6a - 8 =  \\

-  {a}^{2} - a  =  - a(a + 1)

And we're done.

Thanks for watching buddy good luck.
