Answer:
9 + 5t
Step-by-step explanation:
Nine more means 9 plus (9+)
after the 9+, it says 5 times the number of t. That means 5*t, or 5t.
putting them together, you get 9+5t
Answer:
For c=5 there are not solutions for the compound inequality
Step-by-step explanation:
we know that
In the compound inequality
-----> inequality A
-----> inequality B
The solution of the system of inequalities must satisfy inequality A and must satisfy inequality B
so
If c=5
then
There is no solution that satisfies both inequalities simultaneously.
therefore
For c=5 there are not solutions for the compound inequality
Hey there! :D
-2(k-2)≥-20
Distribute the -2. Multiply -2 by k and -2.
-2k+4≥-20
Subtract 4 on both sides.
-2k≥-24
Divide by -2 and flip the sign, since you are dividing by a negative.
k≤12
I hope this helps!

Answer:
Step-by-step explanation:
Given that, a series of triangle,
For the sine and cosine to be equal, then,
Sinθ = Cosθ
From, trigonometry identities
Sinθ = Cos(90-θ)
Then,
θ = 90-θ
θ + θ = 90
2θ = 90
θ = 90 / 2
θ = 45°
From the triangle given, using trigonometry ratio,
Sinθ = opposite / hypotenuse.
Sinθ = 20 / 25
Sinθ = 0.8
θ = arcsin(0.8)
θ = 53.13°
The other angles at the triangle is
90-53.13 = 36.87°.
First, set the mid point of the protractor on the vertex of the angle you want to measure. Then line up one of the sides of the angle with the zero line on the protractor. Lastly, read the degree where the other side crosses into the number scale. Note that a protractor has two sets of numbers and the side on which you measure the angle decides which side you read the protractor from.<span />
