Answer:
Square C is comprised of the areas of squares A and B
It proves that this triangle is a right triangle
By adding the areas of two perfect squares, A and B, square C can only be the sum. This proves the Pythagorean Theorem to be true, as the ratios to the sides, and therefore the equation, will remain fixed in any scalene right triangle.

Answer:
1. AE= 312
2. AC = 161
Step-by-step explanation:
Hey there!
In order to solve the first question, we need to think of possible "C" values
Then after finding the "C" value, we can then find the "A" and "E" values
So:
AC = 24 and CE = 13
What factors do 24 and 13 have in common?
Well, only 1 since 13 is a prime number]
So this means that C has to be 1
Now we know that A is 24 and E is 13
Now we have to multiply them together
24 x 13 is 312
So AE= 312
Now we go on to the second question
We can use the same strategy we used for number one
Instead of finding what C is, we need to find out what E is, since there is E in both of the statements
So:
CE = 7 and AE = 23
What common factors do these two numbers have?
Again, only 1, meaning that E can only be 1
Now we know that C is 7 and A is 23
Since we know this, we can multiply these two numbers together and get our final answer: 161
So AC = 161

Answer:
Exponential growth
how many times greater is 8.5x10^8 than 42x10^7 in scientific notation
Step-by-step explanation:
first, let's bring them to the same exponent of 10.
8.5 × 10⁸ is already scientific notation
42 × 10⁷ = 4.2 × 10⁸ (this is now scientific notation AND it is using the same exponent of 10)
so, how many times is the first one greater ?
(8.5 × 10⁸) / (4.2 × 10⁸) = 8.5 / 4.2 = 2.023809524...
so, the first number is 2.023809524... times greater than the second number.
maybe you made a typo ?
maybe the second number was actually 42.5 × 10⁷ ?
because then
42.5 × 10⁷ = 4.25 × 10⁸
and
8.5 / 4.25 = 2
so,
8.5 × 10⁸ is 2 times greater than 42.5 × 10⁷ or 4.25 × 10⁸.

Find the distance between the points.
(-2.5,3),(5,3)
The distance is ____
Answer:
7.5 units
Step-by-step explanation:
since the y- coordinates of the points are equal, then the distance between them is the absolute value of the difference in the x- coordinates.
distance = | - 2.5 - 5 | = | - 7.5 | = 7.5
or
distance = | 5 - (- 2.5) | = | 5 + 2.5 | = | 7.5 | = 7.5

Three trains are made of identical train cars, so each car has the same number of seats. The first train has 418 seats, the second train has 456 seats, and the third train has 494 seats. How many cars are in each train if no train has more than 25 seats?
In my system the answer format is like this: There were __ cars in the first train, __ cars in the second train and __ cars in the third train
There were _22_ cars in the first train, _24_ cars in the second train, and _26_ cars in the third train
How many cars are on each train?
We know that the trains have 418, 456, and 494 seats. And are made of the same train cars, so the number of seats on each train car is a common factor of 418, 456 and 494.
We also know that no train car has more than 25 seats.
First, let's decompose the given numbers as a product of prime numbers:
418 = 2*11*19
456 = 2*2*2*3*19
494 = 2*13*19
As you can see, the factors 2 and 19 appear in the 3 numbers, 19 is the largest one that is also smaller than 25, so we conclude that each train car has 19 seats.
Then:
The first train, which has 418 seats, has:
418/19 = 22 train cars.
The second train has 456 seats, so it has:
456/19 = 24 train cars
The third train has 494 seats, so it has:
494/19 = 26 train cars.

The smallest value of k when the LCM(Lowest common factor) of 14 and
k is 140 is 10.
What are factors?Factors are numbers or algebraic expressions that divide another number or expression evenly
From the question,
If 14 and k is 140
⇒ (14×k) = 140
⇒ 14k = 140
⇒ k = 140/14

Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value used to test a null hypothesis. Α = 0. 09 for a right-tailed test
From the z table the critical value corresponding to the level of significance level for a two-tailed test is z = 1.64.
How do form the hypotheses?There are two hypotheses. First one is called null hypothesis and it is chosen such that it predicts nullity or no change in a thing. It is usually the hypothesis against which we do the test.
The hypothesis which we put against the null hypothesis is an alternate hypothesis.
The null hypothesis is the one that researchers try to disprove.
From the question, we are told that
The number of observations is greater than 50 i.e. n > 50
The level of significance is [tex]\alpha = 0.1[/tex]
Generally given that n > 30 then we will make use of the z table
So From the z table the critical value corresponding to the level of significance level for a two-tailed test is z = 1.64.
