Answer:

The penguin traveled 68 miles.

Step-by-step explanation:

Given data

  • Rate of swimming (r): 17 miles per hour = 17 mi/h
  • Time of swimming (t): 4 hours = 4 h

We can find the distance (d) that the penguin traveled using the following expression.

d = r × t =  17 mi/h × 4 h = 68 mi ≈ 7 × 10 mi

The penguin traveled 68 miles.

Two systems of equations are shown below: System A System B 2x + y = 5 −10x + 19y = −1 −4x + 6y = −2 −4x + 6y = −2 Which of the
Nezavi [6.7K]

Answer:

They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 3 times the second equation of System A.

Step-by-step explanation:

System A

2x + y = 5 --> (1)

−4x + 6y = −2 --> (2)

(1) + 3×(2)

-10x + 19y = -1

System B

−10x + 19y = −1 --> (1)

-4x + 6y = −2 --> (2)

Answer/Step-by-step explanation:

The angles where two unequal sides of a kite meet are congruent to each other. Thus, these two opposite angles in a kite are equal to each other.

Therefore:

7. <E = <G

Sum of interior angles of a quadrilateral = 360

Thus,

<E = (360 - (150 + 90))/2

<E = 120/2

<E = 60°

<E = <G (set of congruent opposite angles of a kite)

Therefore,

<G = 60°

8. <H = <F (set of congruent opposite angles of a kite)

<F = right angle = 90°

Therefore:

<H = 90°

<G = 360 - (90 + 110 + 90) (sum of quadrilateral)

<G = 70°

9. Based on trapezoid midsegment theorem, the equation should be:

MN = (AB + DC)/2

Thus:

8 = (14 + DC)/2

8 * 2 = 14 + DC

16 = 14 + DC

16 - 14 = DC

2 = DC

DC = 2

10. A kite has only one set of opposite angles that are congruent to each other. The angles where the unequal sides meet, <B and <D, is the only set of angles that are congruent.

Therefore, m<A ≠ 50°

Rather, m<B = m<D = 120°

m<A = 360 - (120 + 120 + 50) (sum of quadrilateral)

m<A = 70°
