Answer:
7.) 16.7
Step-by-step explanation:
7). First you have to find the length of the line with the triangle that is at a 90 angle with the longest side of the triangle
Using the pythagrorem theorem a² + b² = c²
4² + b² = 5²
b² = 5² - 4²
b² = 25 - 16
b² = 9
√b² =√9
b = 3
next you do the same thing to find the missing segment of the longest side
3² + b² = 13²
b² = 169 - 9
b² = 160
b = √160 or ≈ 12.7
12.7 + 4 = 16.7
so 16.7 is the length of that side
Answer:
The answer is (2,3)
Step-by-step explanation:
Answer:
The z-score of a teenage with waist size 33 inch is 2
Step-by-step explanation:
Mathematically, the z-score can be calculated using the formula;
z-score = (x- mean)/SD
where mean = 29 inches , SD = 2 inches and x = 33 inch
Plugging these values, we have
z-score = (33-29)/2 = 4/2 = 2
3/5*3
pretend that 3 has a denominator which is 1
3/5*3/1
mutiply the numerators together
3*3= 9
mutiply the denominators together
5*1= 5
Answer:
9/5, 1.8 and 1 4/5
