Answer:
Step-by-step explanation:
Use Pythagorean theorem,
hypotenuse² = (leg₁)² + (leg₂)²
= 38² + 27²
= 1444 + 729
= 2173
hypotenuse = √2173 = 46.6 cm
addition of signed numbers: -3+2
answer = -1
Answer:
8 cousins
Step-by-step explanation:
B = Bonnie=2*R
R = Robert
G = George = 5 = B -11 (add 11 on both sides of the equation)
B = 5 + 11 = 16 cousins
From B=2*R (substitute the value of B)
16=2*R (divide 2 on both sides of the equation)
R=16/2=8 cousins
Answer:
The answers are A, C, and D
Answer:
Step-by-step explanation:
Corresponding sides of these triangles are proportional, so you have ...
x/5 = 20/x
x² = 5·20 . . . . . . . cross multiply
x = √100 = 10
and ...
y/15 = 5/y
y² = 15·5 . . . . . . cross multiply
y = √75 ≈ 8.7
