7. -9
Step-by-step explanation:
just fill them out to check
Use proportions.
(a)
2 workers are to 19 as x workers are to 38
2/19 = x/38
x = 4
(b)
2/19 = x/76
x = 8
(c)
2/19 = x/133
19x = 2 * 133
19x = 266
x = 14
9514 1404 393
Answer:
x = 14°
y = 5°
Step-by-step explanation:
Angle COL is complementary to both 25° (∠AOC) and 5y (∠LOM). Then it must be true that ...
5y = 25°
y = 5° . . . . . . divide by 5
__
Similarly, angle MOB is complementary to angle LOM, so ...
90° -25° = 3x +23°
42° = 3x . . . . . subtract 23° and simplify
14° = x . . . . . . divide by 3
The values of x and y are ...
Answer:
A. (0, 5)
Step-by-step explanation:
Physically speaking, the volume of the box and the side of the square cutout are positive value. So that the following inequations must be satisfied:
(1)
(2)
(3)
From (1), (2), (3) we find that:
(1):

(2):



(3):



We see that equation above is the multiplication of a first grade monomial and two first grade binomials, which means that:


In other words, the reasonable domain for this situation is A.
