Answer:
a) The volume of concrete needed in cubic feet is 2,112. b) The number of cubic yards of concrete needed in cubic yards is about 79. c) The cost of the concrete using cubic yards is $2,844.
Step-by-step explanation:
a) The formula of the volume is l*w*d. 24 * 11 * 8 = 264 * 8 = 2,112.
b) The way to find this is that you take 2,112 and divide it by 27. Since the answer is 78.2 repeating, you round it up to 79 so it will fill up all of the concrete.
c) Since you need 79 cubic yards of concrete, you do 79 multiplied by $36 to get the total cost of $2,844.

Answer:
The unemployment rate would be 5.5%.
Step-by-step explanation:
It is given that,
The Canadian labor force as of 2019 was 32.7 million.
There were 30.9 million employed
We need to find the unemployment rate.
Unemployed = labor force - employed
= 32.7 - 30.9
= 1.8 million
So, the unemployment rate would be 5.5%.
Answer:
Step-by-step explanation:
x - y = 2√3 given
-y = -x + 2√3 subtract x from both sides
y = x - 2√3 multiply both sides by -1
xy = 1 given
x(x - 2√3) = 1 substitution
x2 - 2x√3 = 1 distribute
x2 - 2x√3 - 1 = 0 subtract 1 from both sides
Can you solve for x then y?
