The simplified mathematical expressions with the first factor to the nearest tenth are:
7.8 x 10
3.3 x 
2.1 x 
3.7
<h3>What are the
simplified mathematical expressions ?</h3>
Scientific notation is used to simplify large numbers in smaller numbers. In order to write a number in scientific notation , the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
(8.6 x 
) . (9.1 x 
)
= (8.6 x 9.1) x 
= 78.26 x
= 7.8 x 10
(6.9 x 
) . (4.8 x )
= 33.12 x 
3.3 x
(3.7 x 
) . (4.6 x ) ÷ (1.4 x 
) . (5.7 x 
)
= 1.7 x 10 ÷ 8 x10²
0.21 x 
2.1 x
(3.1 x ) . (5.3 x 
) ÷ (7.3 x ) . (6.1 x 
) = 3.7

A delightful question.
I think I have it.
The number is 22 .
Its factors are 1, 2, 11, and 22 .
Answer:
(a)205
(b)5 Packages
Step-by-step explanation:
Therefore: 
Therefore, Volume of the lemonade Monica Started with is 
The diameter of the cup =8cm
Therefore, Radius =8/2 =4cm
Height of the Cup =11cm
Volume of a Cone=
The number of cups needed to empty the 10 gallon cooler =37850÷184.31
=205.36
Cups
(b)If the Cups are sold in packages of 50
Number of Package to be bought =205 ÷ 50 =4.1
She would need to buy 5 packages.
I think, not 100% sure, but I think it is square root (A/4pi)=r

Complete Question
Researchers recorded the speed of ants on trails in their natural environments. The ants studied, Leptogenys processionalis, all have the same body size in their adult phase, which made it easy to measure speeds in units of body lengths per second (bl/s). The researchers found that, when traffic is light and not congested, ant speeds vary roughly Normally, with mean 6.20 bl/s and standard deviation 1.58 bl/s. (a) What is the probability that an ant's speed in light traffic is faster than 5 bl/s? You may find Table B useful. (Enter your answer rounded to four decimal places.)
Answer:
0.7762
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation.
Population mean = 6.20 bl/s
Standard deviation = 1.58 bl/s.
x = 5 bl/s
z = 5 - 6.20/1.58
z = -0.75949
The probability that an ant's speed in light traffic is faster than 5 bl/s is P( x > 5)
Probability value from Z-Table:
P(x<5) = 0.22378
P(x>5) = 1 - P(x<5)
= 1 - 22378
= 0.77622
Approximately to 4 decimal places = 0.7762
The probability that an ant's speed in light traffic is faster than 5 bl/s is 0.7762
