Answer:
Prime number: A prime number has factor of only 1 and itself.
Ex: 3: 1 and 3 are the only ways to compose 3.
A whole number that has factors other than 1 and itself is called a composite number.
Ex: 8: the factors of 8 include 1,2,4,8
Circle 5,7,2,19,3,11
Box 18,20,22,16,15,30,26,38,45,10,21,6,14
To determine the prime factorization of a number, you must break down a number into its factors. (im not sure?)
Continute until all of the factors are (im not sure)
Prime factorization is written exponential form (im not quite sure)
30= 2x3x5
30= 2^1 3^1 5^1
24=2 × 2 × 2 × 3
24= 2^3 x 3
sorry idrk if they are all right
Answer:
x = 23, and y = 27.
Step-by-step explanation:
Lets say,
x = width
y = length
this means,
x(2) + y(2) = 100
It also says that the width is 4 meters less than the length.
if we put that into equation form it would look like this,
y - 4 = x
using these 2 equations, we can use the subustusion method to find the x.
x(2) + y(2) = 100
turns in to this :
step 1. (y - 4) (2) + y(2) = 100 - given
step 2. 2y -8 + 2y = 100 - distribute
step 3. 4y -8 = 100 - Combine like terms
step 4. 4y = 108 - Get rid of the 8
step 5 4y/4 = 108 /4 - divide
step 6 . y = 27
So if y is 27, then
x(2) + 27(2) = 100
x(2) + 54 = 100
100 - 54 = 46, so x(2) is 46, but to get x, we need to divide 46 by 2, since x multiplied by 2 equals 46.
46 / 2 = 23 = x
so x = 23, and y = 27.
and the rule that y - 4 = x still applies, since 27 - 4 = 23.
I hope this wasn't confusing! It did take a long time tho.
Answer:
The answer is 3.64m
This is because if you draw a diagram, and label all the sides of the triangle (opp, hyp, adj), the adjacent angle is 3m. You can now use the sine rule to find the hypotenuse (length of ladder) by doing: cos 30= 3/h. You divide cos 30 by 3 and you get the answer of 3.64m rounding to 2 decimal places.
I think it’s BH but don’t get me wrong I don’t fully know
