Answer:
The number of ways he can elect the president,the vice President and the secretary is 1320 ways
Step-by-step explanation:
This is a permutation question.
Any of the 12 members can be the President , when this is done, any of the remaining 11 can be the vice president ,when this is done, any of the remaining 10 can be the secretary.
The required number of ways is;
12*11*10= 1320ways
Answer: 24 cubic inches
Step-by-step explanation:
Answer:
50 times.
Step-by-step explanation:
When the 2 number cubes are rolled once:
The possible outcomes for a total of 7 are:
1 and 6
6 and 1
2 and 5
5 and 2
3 and 4
4 and 3
= 6 outcomes.
The total of all possible outcomes = 6 * 6 = 36.
So Prob( total of 7 in one throw of teh 2 cubes) = 6/36 = 1/6.
For 300 throws you would expect the total of 7 to occur
1/6 * 300 = 50.
Answer:
Part 7) Option C. The approximate perimeter of the patio is
Part 8) Option G.
Part 9)
Step-by-step explanation:
Part 7) we know that
The perimeter of the figure is equal to the circumference of the larger half circle plus the circumference of the smaller half circle plus two times the length of 8 ft
step 1
Find the circumference of the larger half circle
The circumference of the larger half circle is
we have
substitute
step 2
Find the circumference of the smaller half circle
The circumference of the smaller half circle is
we have
substitute
step 3
Find the perimeter of the figure
assume
so
Part 8) we know tat
The area of a circle is equal to
we have
assume
substitute the values and solve for r
Find the diameter D
Divide the width of the pool by the diameter of the floats
so
Part 9)
<em>step 1</em>
Find the circumference of one coaster
The circumference of circle is
we have
assume
substitute
<em>step 2</em>
Find the circumference of 48 coasters
so
<em>step 3</em>
we know that
The laser cut woods at the rate of 3 inches per minute
By proportion find how many minutes will it take to cut out 48 coasters
Answer:
x = 9
Step-by-step explanation:
The slope would be 6
Y -int would be 16
Through this we can find out that the slope-intercept form is
y = 6x + 16
insert 70 into y
solve for x
70 = 6x + 16
54 = 6x
9 = x
