Answer:

AB = CD

Step-by-step explanation:

According to the question, data provided is as follows

AB parallel to CD

AC and BD both are perpendicular to AB and CD

Based on the above information, the relationship between AC and BD is

As we know that

Since AC and BD both are perpendicular to AB and CD and these two are parallel. That means they have the same direction as they are parallel

Moreover, in the case of parallel lines, the perpendicular distance between these two lines would remain the same

Therefore

AB = CD

Question 14 of 40

tester [92]

Answer:

B. 18

Step-by-step explanation:

Quadrilateral ABCD is a rectangle.

Diagonals AC and BD intersect at point E.

Diagonals of a rectangle are equal in length.

$\implies BD = AC$

Diagonals of a rectangle bisect each other.

$\implies\frac{1}{2} BD = \frac{1}{2} AC\\\\\implies DE = \frac{1}{2} \times 36\\ \\ \implies DE = 18$

Margaret [11]

Answer:

a). 240 miles (Approx)

b). Trip can't be covered in 3 hours with a constant speed = 70 miles pr hour

Step-by-step explanation:

a). As the scale has been given at the bottom. Length of the scale represents the distance between two points.

Now by measuring the distance between these stations, approximate distance between Amarillo and Oklahoma = 4(length of the scale)

= 4×60

= 240 miles.

b). Driving at a constant speed = 70 miles per hour

Distance covered in 3 hours = 70 × 3

= 210 miles

Therefore, distance of 240 miles between these stations can't be covered with the driving speed 70 miles per hour in 3 hours.

An egg of a certain kind of insect called a Tachinidae is 0.00002 meters

postnew [5]

The length in scientific notation is $2 \times 10^{-5}$ meters

Solution:

Given that egg of a certain kind of insect called a Tachinidae is 0.00002 meters long

To find: length in scientific notation

Given length in meters = 0.00002 meters

Let us understand about scientific notation

Scientific notation is a mathematical expression used to represent a decimal number between 1 and 10 multiplied by ten, so you can write large numbers using less digits

Rules for scientific notation:

Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.

Count how many places you moved the decimal point. This number is b.

If you moved the decimal to the left b is positive.

If you moved the decimal to the right b is negative.

If you did not need to move the decimal b = 0.

Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."

Remove trailing 0's only if they were originally to the left of the decimal point.

Converting 0.00002 meters to scientific notation:

Here we move the decimal point to right side. Move the decimal point 5 times so that only "2" is present to left of decimal point

Since decimal point is moved to right, the exponent 5 is negative(-5)

$\rightarrow 2 \times 10^{-5}$

Thus the length in scientific notation is $2 \times 10^{-5}$ meters
