Answer:

0.4 second

Step-by-step explanation:

The formula D = st is the formula that can be used to substitute in the values (which is already in the problem).

If the speed is 175 meters a second and the distance is 70 meters, than that means 70 = 175t.

(I substituted 70 for distance, or D, and 175 for speed, or s).

Divide 175 on both sides in order to isolate the variable (t), which is 0.4 second.

The time taken for the hurricane to reach the shore would be 0.4 second.

Answer:

Answer is given below with explanations.

Step-by-step explanation:

Answer is option 1) 85 : 51

$given \: that \: \\ triangle \: SPT \: is \: similar \: to \: triangle \: QPR \\ corresponding \: sides \: of \: similar \: \\ triangles \: are \: in \: proportion \\ then \: \\ \frac{SP}{ QP} = \frac{PT }{ PR} \\ \frac{3x}{3x + 24} = \frac{51}{85} \\ taking \: reciprocal \: on \: both \: sides \\ \frac{3x + 24}{3x} = \frac{85}{51}$

Option 1 is correct.

I need help prove that the quadrilaterals are a parallelogram

Vlad1618 [11]

Answer:

The only shape you can make is a parallelogram. If both pairs of opposite angles of a quadrilateral are congruent, then it's a parallelogram (converse of a property). If the diagonals of a quadrilateral bisect each other, then it's a parallelogram (converse of a property).
