19 is the answer to this question
Answer:
314 in²
Step-by-step explanation:
The formula for the area of a circle is pi*r² or pi (3.14...)* radius²(squared).
If you plug in the radius given into the equation, you get 3.14*10² you can then solve this using systems of equations.
3.14*10²
10² = 10*10
3.14*(10*10)
10*10= 100
3.14*100
3.14*100= 314
Hi there!
In order to find your answer, you'll need to use the cross product method :
150 miles → 2 1/2 hours = 150 minutes
x miles → 3 hours = 180 minutes
(150 × 180) ÷ 150 = x miles
27,000 ÷ 150 = x miles
180 = x miles
Your answer is: A train would cover 180 miles in 3 hours.
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
3(t)-3(2)=3t - 6
Step-by-step explanation:
multiply each number in the parentheses by 3.
The statement which is true in the choices is the third item in the choices such as "Nina makes 20x dollars at the clothing store each week". It was clearly stated in the given that x represent the total number of hours she worked in a week. This statement made the other items in the choices wrong.
