Which situations can be simulated using this spinner? Select three options.A spinner with 6 equal sections.
A: Predicting the gender of a randomly chosen art teacher if 1 of 3 art teachers is female
B: Predicting the gender of a randomly chosen history teacher if 12 of 15 history teachers are female
C: Predicting the gender of a randomly chosen biology teacher if 8 of 12 biology teachers are female
D: Predicting the gender of a randomly chosen chemistry teacher if 4 of 9 chemistry teachers are female
E: Predicting the gender of a randomly chosen health teacher if 2 of 4 health teachers are female

Answer:
A: Predicting the gender of a randomly chosen art teacher if 1 of 3 art teachers is female.
C: Predicting the gender of a randomly chosen biology teacher if 8 of 12 biology teachers are female.
E: Predicting the gender of a randomly chosen health teacher if 2 of 4 health teachers are female.
Step-by-step explanation:
Notice that the spinner has 6 equal sections.
So, all situations that can be simulated with such spinner must be multiples, divisors of 6, or a number least than 6, that way, we could use the 6 equal-section spinner.
Option A uses 1 of 3, Option B uses 8 of 12, and Option E uses 2 of 4.
Therefore, the anwers are A, C and E.
Answer: A C E

pack-out rate. The blueberry harvester machine collects about
22,000 pounds of blueberries per day with a 90% pack-out rate.
The pack-out rate is the percentage of collected blueberries
that can be packaged to be sold, based on Florida Blue Farms'
quality standards.
Let h represent the number of days the hand pickers work and
m represent the number of days the harvester machine is used.
Which of the following algebraic expressions can be used to
estimate the amount of collected blueberries that are packed at
the Florida Blue Farms for fresh consumption this season?
A (0.95h+200)(0.90+22000)
B 0.95(200h)+0.90(22000m)
C 200.95h+22000.90m
D (200h+0.95)(22000m+0.90)
Answers
The farm uses two harvesting tools for packages that needs to be sold. So, we have to consider the rates of both harvest tools and the number of harvest by both tools. The algebraic expression is:
Given that
days of hand pickers word
days harvester machine is used
--- pounds of hand pickers
-- pounds of harvester
-- pack out rate of hand pickers
-- pack out rate of harvester
The expression to estimate the amount is calculated as:
--- i.e. pounds of hand picker * its pack out rate + pounds of harvester * its pack out rate
So, we have:
Express as decimal
Rewrite as:
Hence, option (b) is correct.

Answer: This turn will make a change of 45 minutes.
Step-by-step explanation: Now, a full turn of the minute hand in a clock face is an hour or 60 minutes.
Now, if we only do a 3/4 of a turn, the number of minutes passed is equal to:
3/4*60min = 45min
So in a 3/4 turn of the minute hand, the "change" in the time will be one of 45 minutes.

=> 82 - 50 = 32
Now how many percent is 32 out of 50?
=> 32 / 50 = 0.64
=> 0.64 * 100% = 64%
thus 64% added or increased in the previous number.

Rotation 90° about the origin will result in the following:
(x,y) ..........> (-y,x)
Therefore, you have to multiply the y value by -1 and then flip the x and y.
Examples:
(2,9) ..........> Rotation 90° about the origin .........> (-9,2)
(-3,4) .........> Rotation 90° about the origin .........> (-4,-3)
(-1,0) ..........> Rotation 90° about the origin .........> (0,-1)
(8,-6) ..........> Rotation 90° about the origin .........> (6,8)
Hope this helps :)

x+3=0.9
minus 3
x=2.1
Divide both sides by 10
x+3=9 / 10
Subtract 3 from both sides
x=9 / 10 −3
Simplify 9 / 10 −3 to −21 / 10
x=−21 / 10
Decimal = -2.1

1/8 x 4 = (1*4) / 8 = 4/8 = 1/4
1/4 x 3 = (1*3) / 4 = 3/4

Total number of tomatoes = 4 + 3 + 2 + 3 + 1 + 1 + 1 = 15 tomatoes
Total weight = 1/4 + 3/4 + 3/4 + 3/2 + 5/8 + 7/8 + 3/4
1/4 * 2/2 = 4/8
3/4 * 2/2 = 6/8
3/2 * 4/4 = 12/8
4/8 + 6/8 + 6/8 + 12/8 + 5/8 + 7/8 + 6/8 = 46/8 total weight in pounds
46/8 ÷ 15 tomatoes = 46/8 * 1/15 = 46/120 = 23/60 average weight per tomato
