u = 10.4 and v = 12
Solution:
In the given 2 sides of a triangle are 60°, 60°.
Sum of all the angles of a triangle = 180°
60° + 60° + third angle = 180°
⇒ third angle = 180° – 60° – 60°
⇒ third angle = 60°
All angles are equal, therefore the given triangle is an equilateral triangle.
⇒ All sides are equal in length.
⇒ v = 12
The line drawn from the top angle divides the triangle into two equal parts
and the line is perpendicular.
12 ÷ 2 = 6
Using Pythagoras theorem,

⇒ 
⇒ 
⇒ 
⇒ 
⇒ u = 10.4
Hence, u = 10.4 and v = 12.
The answer would be E because as you may know, 10 mm is equal to 1 cm. So, 230 mm³ is equal to 23 cm³.
Answer:
Domain of the function is (inf, -inf)
Step-by-step explanation:
The answer to the first part is 172 plants per row with a remainder of 3 plants
The answer to the second part is, Martin knows that 7 goes into 700 100 times, 7 goes into 490 70 times, and 7 goes into 17 twice with a remainder of 3. He then adds 100 70 and 2 together to get 172 with a remainder of 3.
6.9 x 10⁷ is a scientific notation.
6.9 x 10⁷ in standard form is 69,000,000
Scientific notation is used to represent very large numbers or very small numbers.
Scientific notation has three parts. Its parts are the coefficient, base of ten, and the exponents.
6.9 is the coefficient
10 is the base of 10
7 is the exponent
The must always be 1 digit before the decimal point in the scientific notation.
The exponent tells us the number of places the decimal point has moved. Its sign tells us the direction of the decimal point's movement.
Since the exponent is positive, it tells us that the decimal point moved from right to left.
69000000. to 6.9000000
If the exponent had a negative sign, it means that the decimal point moved from left to right.
example: 6.9 x 10⁻⁷
its standard form would have been .00000069
