-----> exact value of the volume
Answer:
7
Step-by-step explanation:
28 ÷ 16 = 1.75
1.75 × 4 = 7
The way I did it is by finding out how much bigger 28 is than 16 by dividing and then I multiplied the answer (1.75) by 4 to get the bigger answer. The problem is showing you that the triangles are the same just different sizes.
Given:
right triangle
a = 2.9
c = 4.2
Pythagorean Theorem: a² + b² = c²
missing value of b.
b² = c² - a²
b² = (4.2)² - (2.9)²
b² = 17.64 - 8.41
b² = 9.23
b = √9.23
b = 3.03 or 3.0
The value of b is 3.0
Slope =2/3
70,80) (10,40)
(80-40)/(70-10) = 40/60
4/6
2/3
