3.36 cm
Step-by-step explanation:
from the passage before ; the figure of question is similar to the first figure in passage because those triangles have an each equal angle.
Therefore the ratio of side is equal ; 1/0.84=4/x
Solve equation will be x(1)=4(0.84) ; x=3.36 cm
Answer:
431 and 43
Step-by-step explanation:
Two numbers: y1 and y
Number one: y1 = 10 * y + 1
(10 * y + 1) + y = 474
11y = 473
y = 43
Two numbers: 431 and 43
check: 431 remove 1 (digit) -> 43
431+43=474
The inequalities are x>3y, 15x+25y≥700 (or 3x+5y≥140).
These are satisfied by (45,10) and (40,5).
