Answer:
m ≤ 54
Step-by-step explanation:
Add 18 to both sides.
m -18 +18 ≤ 36 +18
m ≤ 54 . . . . . simplify
Amount paid by Mary for her computer is
.
<u>Solution:
</u>
Given that, Sam purchased a computer for
.
Price of the printer that Mary purchased was
the price that Sam paid.
Need to calculate amount Mary pay for her computer. Assuming that Mary purchased same computer that is purchased by Sam and store selling the computer have same rates for all customers
.
So, amount Mary pay for computer = Amount Sam paid for computer =
Hence, amount paid by Mary for her computer is
.
Answer:
87.0°
Step-by-step explanation:
The law of sines can be used to solve this. We have two sides of a triangle and the angle opposite one of them. We want to find the angle opposite the other known side.
In the attached, the triangle is ΔACS. We have side "a" = 9, and side "c" = 10. Angle A is given as 64°. The law of sines tells us ...
sin(C)/c = sin(A)/a
sin(C) = (c/a)sin(A)
C = arcsin((c/a)sin(A)) = arcsin(10/9·sin(64°)) ≈ 87.03°
The ladder makes an angle of about 87° with the ground.
