Answer:
10.9
Step-by-step explanation:
You can solve this using the Pythagorean theorem, a^2+b^2=c^2, since it will form a right triangle.
You aren't missing the hypotenuse (c), but one of the side lengths (b). But you still solve like a normal algebraic equation.
Plugging in your values, you should start with 5^2+b^2=12^2
Then square everything.
25+b^2=144
Take away 25 from both sides.
b^2= 119
Then square root both sides.
b= 10.9
Answer:
See below
Step-by-step explanation:
<u>Assumed you need to solve the system:</u>
- 12x - 2y = - 1
- 4x + 6y = - 4
In order to solve this by elimination, triple the first equation and add the second one.
<u>It will make the coefficients of y same with opposite signs:</u>
When added together these cancel, leaving x as the only variable.
the answer is D if it is not then try A
Answer:
a.2010 rad/min
b.2412 feet/min
Step-by-step explanation:
We are given that
Diameter of wheel,d=2.4 feet
Radius,r=

1 rev= radian
320 rev/minute=
Where
Angular speed=
b.Speed,v=
Step-by-step explanation:
Answer:
V = 205 in^3 to the nearest whole number
Step-by-step explanation:
V = 4/3 π r^3
Plugging in the given information:
V = 4/3 * 3.14 * 7^2
V = 205.147.
