Answer:

There are six important properties of parallelograms to know:

Opposite sides are congruent (AB = DC).

Opposite angels are congruent (D = B).

Consecutive angles are supplementary (A + D = 180°).

If one angle is right, then all angles are right.

The diagonals of a parallelogram bisect each other.

Each diagonal of a parallelogram separates it into two congruent triangles.

ryzh [129]

y=7m+6

subtract 6 from each side

y-6 = 7m

divide by 7

(y-6)/7 =m

A = 6b

divide by 6

Scilla [17]

Answer:

Hence, the correct option is 82%.

Step-by-step explanation:

Consider the provided information.

In your university nursing program the ratio of students who scored a grade of A vs B vs C on the final exam is 12:29:9.

We need to find the percentage of student who scored a grade of "B" or higher.

Let x is the common factor for the proportion.

Then, the number of students who got grade A is 12x

The number of students who got grade B is 29x

The number of students who got grade C is 9x.

Thus the total number of students = 12x+29x+9x = 50x

The percentage of student who scored a grade of "B" or higher:

12x+29x = 41x

$\frac{41x}{50x}\times{100}=82\%$

Hence, the correct option is 82%.

9. The longitude of a geographic location is measured in degrees east (E) or west (W) from the

alexandr402 [8]

Based on the longitudes of Quito and Singapore, the shortest distance between the two areas is 19,702.5 km .

<h3>How far is Quito from Singapore?</h3>

Because both cities are close to the equator, you use the longitudinal difference method to find the shortest distance.

First find the difference in longitudes:

= Singapore - Quito

= 104 - (-78.5) because Quito is west

= 104 + 78.5

= 182.5°

Then subtract this from 360°:
= 360 - 182.5

= 177.5°

Every 1° longitude along the Equator is 111 km so the shortest distance is:

= 177.5 x 111

= 19,702.5 km
