notice |7| 7 is positive, so we can simply remove the bars and use 7 by itself
we know that
1 ft--------> is equals to 12 in
the ramp is 12 inches tall----------> 1 ft tall
A ramp measures------------------> 6 ft long
applying the Pythagorean theorem
c²=a²+b²
where
c-----> 6 ft long
a----> horizontal distance
b-----> 1 ft tall
a²=c²-b²------> a²=6²-1²-----> a²=35------> a=√35------> a=5.92 ft
the answer is
5.92 ft
Answer:
Cos A = 24/25 & Tan A = 7/24
Step-by-step explanation:
See the attached figure.
Construct a right triangle and sign one angle as A
So, Sin A = opposite/hypotenuse = 7/25
∴hypotenuse = 25 and opposite = 7
∴ adjacent = √(25² - 7² ) = √576 = 24
∴ Cos A = adjacent/hypotenuse = 24/25
And
Tan A = opposite/adjacent = 7/24
Answer:
I think it's 123 if not sorry
Step-by-step explanation:
all you need to do is 180 - 57 to get your answer
Answer: D) 8 hours
Step-by-step explanation:
Machine A: 840 an hour
Machine B: 760 an hour
h = hour
840 + 760 = 1600
In an hour, they can both sort 1600 mails.
1600h = 12800
Divide each side by 1600
h = 8
840 * 8 = 6720
760 * 8 = 6080
6720 + 6080 = 12,800
