Answer:
2π
Step-by-step explanation:
Area = πr^2
= π2^2
= 4π
4π is the area of the whole circle, so divide it in half to get the semicircle.
<u>= 2π</u>
Answer:
<u>The track consumes ≅ 61 liters of fuel every 100 kilometres</u>
Step-by-step explanation:
As we can see in the graph, the total distance that the truck can travel with 500 liters of fuel is ≅ 825 kilometres.
For answering the question properly, we use the Rule of Three Simple, this way:
Kilometres Liters of fuel
825 500
100 x
Solving for x, we have:
825 * x = 500 * 100
825x = 50,000
x = 50,000/825
x = 60.6 liters of fuel (61 rounding to the next whole)
x ≅ 61 liters of fuel
<u>The track consumes ≅ 61 liters of fuel every 100 kilometres</u>
Answer:

Answer:
y=-4
Step-by-step explanation:
Answer:
Step-by-step explanation:
okay, to start, lets rewrite this so there are no weird symbols:
so, we are going to multiply the coefficients first. ( -2 times 4)
we get -8. now, when you multiply variables that have exponents, we actually add the exponents. remember it is like terms, so a goes with a and b goes with b. so, the 
times 
would equal 
. (because a is the same thing as 
).
now lets look at b. 
times would equal 
. so, because we have multiplied the parentheses, lets look at what we have. we have -8, , and . we need to remember that these were originally multiplied by each other, so we are going to write it that way. . we always write coefficients first, and then the variables in the order of the alphabet. i hope this helps and have a great day!
