Answer:
If it had more time as a fossil then it is the oldest
Step-by-step explanation:
<h2>SOLUTION </h2>
Given that:
- Edge of the square pyramid = 14 unit
- Slant height of the square pyramid = 25 unit
To Find:
- The height of the square pyramid.
We know that:
In pythagoras theorem.
Where,
- H = Hypotenuse = 25 unit
- P = Height = Let x
- B = Base = 14/2 = 7 unit
Finding the height of the square pyramid:
⇒ H² = P² + B²
⇒ (25)² = x² + (7)²
⇒ 625 = x² + 49
⇒ x² = 625 - 49
⇒ x² = 576
⇒ x = √576
⇒ x = 24
Hence,
- The height of the square pyramid is 24 unit
Remark
Answer: The second one. The second step removes the brackets on the right. It uses the <em><u>distributive property</u></em> which puts back the common factor that was taken out of the two terms 6x and 24. Quite often the distributive property is useful when presenting a problem to be solved.
The associative property is more of an order thing and that is very useful sometimes as well what it says is that if you have three numbers a + b + c the order which you combine things does not matter.
For example 3 + 4 + 5 could be combined as 3 + 4 = 7; 7 + 5 = 12 or 3 + 5 = 8, 8 + 4 = 12.
The associative property is useful when adding fractions.
Answer: 32%
Step-by-step explanation:
The total number of students that signed up for chemistry and algebra
two is 386.
Let x represent the number of students that signed up for both chemistry and algebra two
If 209 students signed up for algebra two, then the number of students that signed up for algebra two only is
209 - x
If 300 need to have signed up for chemistry, then the number of students that need to have signed up for chemistry only is 300 - x
Therefore,
x + 209 - x + 300 - x = 386
- x + 509 = 386
x = 509 - 386
x = 123
If 123 students would be signed up for both courses, then the probability that a student chosen at random from the 386 will be signed up for both of the courses is
123/386 × 100 = 32%
Answer: no real solution
Step-by-step explanation:
X^2 - 6 + 9 = 0
Step 1: Simplify both sides of the equation.
x^2+3=0.
Step 2: Subtract 3 from both sides.
x^2+3−3=0−3
x^2=−3.
Step 3: Take square root. x=±√−3
answer is No real solutions.
