Answer:
To find h the altitude we use sine
sin ∅ = opposite / hypotenuse
From the question
AC is the hypotenuse
h is the opposite
sin 29 = h / 23
h = 23 sin 29
h = 11.1506
h = 11.00mm to the nearest hundredth
Hope this helps you
Here is the equation:
⇒
You need to get "x" by itself so minus 3 from each side
⇒
⇒
Divide 8 by 2
÷
x=4
So each 4 is equivalent to 4
Lets check:

So that means that Marcus practiced the piano for 4 hours and Donnel practiced for 7
-30x cubed
There are three x hence the cubes and then all you do is multiply (5)(-2)and(3) together to get -30
Answer:
5 + 3.5h = 29.50
Step-by-step explanation:
The flat fee means that you will be paid the money with no change to it.
So you will not multiply it.
3.5h means that you are adding 3.50 every hour according to the question
So summary:
5+3.5h = 29.50
Evaluation:
5+3.5h = 29.50
24.50 = 3.5h
h = 7

Answer:
950.455in^3
Step-by-step explanation:
Given data
Circumference= 11π
Also, the expression for circumference is
C=2πr
11π=2πr
solve for r
r= 11π/2π
r= 5.5in
Given that the Height h= 10in
The expression for the volume is
V= πr^2h
V=3.142*5.5^2*10
V=3.142*30.25*10
V=950.455 in^3
Hence the volume is
950.455in^3
