Based only on the given information, it is guaranteed that AB is perpendicular to CD. True or false

Answers

Answer 1

Answer:

Answer:

true

Step-by-step explanation:

because CD divided AB into equal halves, so they are of course perpendicular.

Answer 2

Answer:

Answer:

Step-by-step explanation:

This is definitely true. AC is congruent to BD, and by the Isosceles Triangle Theorem, if this congruency is true, then the angles across from these congruent sides are also congruent. This means that angle ACD is congruent to angle BCD. That makes CD a bisector of angle ACB; it also makes CD a bisector of side AB. The definition of a perpendicular bisector is that the segment splits its angle in half (and it does) and that it splits the side it goes through in half (which it does). This makes CD, in a nutshell, the perpendicular bisector of AB (which also means that CD is perpendicular to AB).

C2d3 has a solubility product constant of 9.14×10−9. what is the molar solubility of c2d3?

Answers

The correct answer for the question that is being presented above is this one:

We need to express the ksp expression of C2D3
C2D3
= (2x)2(3x)3
= 108x5

Then set that equation equal to your solubility constant

9.14x10-9 = 108x5
x = 9.67x10-3

So the molar solubility is 9.67x10-3

OK so you have x and 16 and 14 so you have to use the formula a^2 + b^2 = c^2 to find your answer

if you look at your triangle the long side is 16 the middle side is 14 is you subtract the 14 from 16 y=2

Given: 5 > x + 7. Choose the solution set.

{x | x R, x > -2}
{x | x R, x < -2}
{x | x R, x > 2}
{x | x R, x < 2}

Answers

Answer:

{x | x R, x < -2}

Step-by-step explanation:

Answer:

x is less than negative 2

Step-by-step explanation:

Using the properties of addition, we move the 7 over to the five, making it negative.

This makes negative 2 because we subtract 7 from 5.

Then, we can flip the equation to understand it better, making the x in the front.

This makes the final solution x is less than -2

If I read 52 pages in 2 hrs and Tim reads 1/4 more in 2 and1/2 hr. who read faster?

Answers

They read at the same speed
If we split the time where you read into half hour intervals we would have
13 pages per 30 minutes
and since $(1)/(4)$ * 52= 13 and the time added is 30 minutes we know that You and Tim read at the same speed.

so Tim read 13 pages =1/4 of 52 pages in (2 and 1/2 hr) - (2hrs) = 1/2 hr
So Tim will read 26 pages in 1 hr and that means Tim read 52 pages in 2 hrs, the same with You! The answer its that bouth read in the same time.

If AD = 6 meters, which does AB equal? Select one of the options below as your answer:
A.6 meters
B.10 meters
C.12 meters
D.15 meters

Answers

AD = 6 m
AB is a hypotenuse and AD is an adjecant.
cos 60° = AD / AB
AB = AD / cos 60°
AB = AD : 1/2
AB = 6 : 1/2 = 12
Answer:
C ) 12 meters
