Determine the correct equation used in order to solve the problem "The number 24 is what percent of the number 40?"

lions [1.4K]

The correct equation that represents the expression "The number 24 is what percent of the number 40?" is as shown below;

The the unknown number in percent be 'x'

x percent of number 40 is expressed as;

x% of 40

x/100 of 40

If 24 is equal to the expression above, then the final equation will be expressed as;

24 = x/100 of 40

24 = 40x/100

24 = 0.4x

Rearrange

0.4x = 24

Hence the correct equation used to solve the problem is 0.4x = 24

Factor the trinomial below. x^2 + 5x – 24 A. (x – 8)(x + 3) B. (x – 4)(x + 6) C. (x – 3)(x + 8) D. (x – 6)(x + 4)

abruzzese [7]

Answer:

<h3>The answer is option C</h3>

Step-by-step explanation:

x² + 5x - 24

To factorize first write 5x as a difference so that when subtracted will give you 5 and when multiplied will give you - 24

That's

x² + 8x - 3x - 24

Factorize x out

That's

x( x + 8) - 3(x + 8)

Factor x + 8 out

We have the final answer as

Hope this helps you

To prove the QRST is a parallelogram.

Step 1: Given $\angle T \cong \angle R$ and $\overline{Q R} \| \overline{T S}$

Step 2: $\angle R Q S \text { and } \angle T S Q$ are alternate interior angles.

Definition of alternate interior angles

Step 3: Alternate interior angle theorem:

If two parallel lines cut by a transversal then the alternate interior angles are congruence.

QR and TS are parallel lines cut by QS.

Therefore, $\angle R Q S \cong \angle T S Q$

Step 4: Reflexive property of congruence:

Any geometric figure is congruence to itself.

Therefore, $\overline{Q S} \cong \overline{Q S}$

Step 5: By the above steps

$\angle T \cong \angle R$ (Angle), $\angle R Q S \cong \angle T S Q$ (Angle) and $\overline{Q S} \cong \overline{Q S}$ (Side)

Hence $\triangle Q T S \cong \triangle S R Q$ (by ASA congruence theorem)

Step 6: Corresponding parts of congruence triangles are congruent.

$\Rightarrow \ \overline{Q R} \cong \overline{T S}$

Step 7: Property of parallelogram:

If one pair of opposite sides are both parallel and congruent, then the quadrilateral is a parallelogram.

Hence Quadrilateral QRST is a parallelogram.
