Answer:
36π
Step-by-step explanation:
The formula for the area of a circle is π times radius squared.
The radius in this case is 6, so squaring it gets us 36.
Multiplying this by π gets 36π.
Answer:
There are 20 million people in the labour force.
Step-by-step explanation:
There are 50 million people in the country.
30 million people are adults.
Out of the 30 million, 5 million are not interested in working. Assuming every adult does what he/she wants, then these 5 million are not working. The list then reduces to
30 - 5 = 25 million.
Another 5 million are interested in working but have given up looking for work. The list reduces to
25 - 5 = 20 million.
5 million people are working part time but would like to work full time. They are working, it doesn't matter if it is part time or full time, they are in the labour force.
10 million people are working full time. They are also in the labour force.
THERE ARE 20 MILLION PEOOLE IN THE LABOUR FORCE
Answer:
(5,-6) I think
Step-by-step explanation:
b = 1/6
Explanation:
3x-y=4 ...1st equation
Rewriting in slope- intercept form:
y = 3x - 4
2y+4bx=1
Rewriting in slope- intercept form:
2y = -4bx + 1
y = -4bx/2 + 1/2
Equation of line: y = mx + c
where m = slope, c = intercept
For a line to be perpendicular to another, the slope of one will be the negative reciprocal of the slope of another.
Slope of the 1st equation = 3
m = 3
reciprocal of 3 = 1/3
negative reciprocal of 3 = -1/3
Slope of the 2nd equation = -4b/2
we equate both slope:
negative reciprocal of 3 = -4b/2
-1/3 = -4b/2
cross multiply:
-1(2) = 3(-4b)
-2 = -12b
Divide both sides by -12:
-2/-12 = -12b/-12
b = 1/6
Hence, the value of b that makes the lines perpendicular is 1/6
We first write the fractions in their decimal forms and find out the ratio.
2 1/4 is equivalent to 2.25, and 1 1/3 is equivalent to 1.33
Ratio will be 2.25 / 1.33 = 1.69 or 1.7 rounded off. Since it cannot be simplified further, then the ratio of mulch to gravel will be 1.7: 1
Quantity of mulch sold → 1.7/2.7 of 172 →0.629 ×172 = 108.2 pounds
Quantity of gravel sold will be 172 -108. 2 = 63 .8 pounds
