Answer:
F = 160 pounds
B. 160 pounds
Step-by-step explanation:
F = k / l
Where,
F = amount of force needed
l = length of the lever
k = constant of proportionality
F = 240 when l = 24 inch
F = k / l
240 = k / 24
Cross product
240*24 = k
k = 5,760
Find F when l = 36 inch
Recall, k = 5,760
F = k / l
= 5,760 / 36
= 160
F = 160 pounds
The correct answer is B. 160 pounds
Answer: 16a + 32b - 8c
Step-by-step explanation:
8(2a + 4b - c ) = 16a + 32b - 8c
Multiply 8 by 2a to get 16a
Multiply 8 by 4b to get 32b
Multiply 8 by -c or -1c to get -8c
Put them together to get 16a + 32b - 8c
The overall answer is d=16.76
If you are looking for just the answer to (0.3D-1.5)/3 than that is 0.1d-05.
I don’t exactly understand what you want me to solve so I gave you two answers.!
Answer:
A = 52°, a = 149.2, c = 174.3
Step-by-step explanation:
Technology is useful for this. Many graphing calculators can solve triangles for you. The attachment shows a phone app that does this, too.
___
The Law of Sines can give you the value of c, so you can choose the correct answer from those offered.
c = sin(C)·b/sin(B) = sin(113°)·49/sin(15°) ≈ 174.271 ≈ 174.3 . . . . . third choice
Answer:
(1)-5x (2)-3x and 0x
Step-by-step explanation:
(1) -7x-2y=5
-7x-12=5
(2) y=-8x+5=-3x
y=-5x+5=0x
