Answer:
The height is 6 feet, and the length of the ramp is the hypotenuse of a right triangle with angle 28 degrees with the ground
Step-by-step explanation:sin
28=6/x
x*sin 28=6
x=6/sin 28=12.78 ft.
Not A because:
(Subtract 11 from both sides)
4n > -20
(Divide both sides by 4)
n > -5
Because we have found that dividing the negative number by 4 does not work, we know B is also wrong.
Not C because:
(Subtract 11 from both sides)
-4n < -20
(Divide each side by -4)
(Reverse inequality sign because you are dividing by a negative number)
n > 5
So, it must be D!
Here's why:
(Subtract 11 from both sides)
-4n > -20
(Divide each side by -4)
(Reverse inequality sign because you are dividing by a negative number)
n < 5
Hope this helps!
Answer:
270
Step-by-step explanation:
its on my test this is the right answer
Answer:
Step-by-step explanation:
Given:
For Δ ABC
m∠A=°
m∠B=°
m∠C=°
To find value of .
Solution:
For all triangles the sum of all 3 angles = 180°
Thus, we have:
Plugging the values in degrees.
Combining like terms.
Subtracting both sides by 6.
Dividing both sides by 6.
∴ (Answer)
Answer: 20 hours
Step-by-step explanation:
Since, One watch is slow and loses two minutes every hour
⇒ 1 hour of slow watch = 62 minutes
And, the other one is fast and gains one minute every hour.
⇒ 1 hour of fast watch = 59 minutes,
Hence, in 1 hour, the difference between slow and fast watch in 1 hour = 62 - 59 = 3 minutes.
⇒ The between slow and fast watch in 20 hours = 20 × 3 = 60 minutes or 1 hour.
Hence, after 20 hours the difference between the watches will be 1 hours.
