Answer:

Rectangle always have congruent diagonals.

Step-by-step explanation:

Given some figures kite, quadrilateral, rectangle and rhombus. we have to find which of these always have congruent diagonals.

The diagonals of a kite intersect at a right angle and have exactly one pair of opposite angles congruent. But does not have congruent diagonals.

If the quadrilateral is rectangle, square, isosceles trapezoid then only the diagonals are congruent.

Rhombus also does not have congruent diagonals.

The only option whose diagonals are congruent is rectangle.

valentinak56 [21]

Answer:

Approximately 54.54% of race happened in the first week.

Step-by-step explanation:

We are given the following in the question:

Length of bike race in three weeks = 2,200 miles

Race covered in first week = 1,200 miles

Percentage of race covered in first week =

$=\dfrac{\text{Race covered in first week}}{\text{Total length of race}}\times 100\%\\\\=\dfrac{1200}{2200}\times 100\%\\\\=54.54\%$

Thus, approximately 54.54% of race happened in the first week.

Answer:

b. {-9, 3}.

Step-by-step explanation:

x^2 + 6x - 27 = 0

We need 2 numbers whose product is -27 and whose sum is + 6.

These are + 9 and - 3. So the factors are:

(x - 3)(x + 9) = 0

(x - 3) = 0 or (x + 9) = 0

x = 3 or -9.
