Answer:
5/3
Explanation:
The given is:
70/42
We can start by dividing both the numerator and denominator by 7 as follows:
(70/7) / (42/7)
10 / 6
The result can be further simplified by dividing both the numerator and the denominator by 2 as follows:
(10/2) / (6/2)
This will give us:
5/3
The reached result cannot be further simplified.
Therefore:
70 pounds to 42 pounds is equivalent t 5 pounds to 3 pounds in the simplest form.
Hope this helps :)

4.32/12 = .36 per ear of corn
Answer: a. 0.14085
b. 3.826 x 
c. 0.5437
d. 0.0811
Step-by-step explanation:
Given average amount parents and children spent per child on back-to-school clothes in Autumn 2010 , 
= $527
Given standard deviation , 
= $160
Let X = amount spent on a randomly selected child
Also Z = 
a. Probability(X>$700) = P( > 
) = P(Z>1.08125) = 0.14085 {Using Z % table}
b. P(X<100) = P( Z < 
) = P(Z< -2.66875) = P(Z > 2.66875) = 3.826 x
c. P(450<X<700) = P(X<700) - P(X<=450)
P(X<700) = 1 - P(X>=700) = 1 - 0.14085 = 0.8592
P(X<=450) = P(Z<= 
) = P(Z<= -0.48125) = P(Z<=0.48125) = 0.3155
So final P(450<X<700) = 0.8592 - 0.3155 = 0.5437
d. P(X<=300) = P(Z<= 
) = P(Z<= -1.4188) = P(Z>=1.4188) = 0.0811
All the above probabilities are calculated using Z % table along with interpolation between two values.
If we're talking about a box with dimensions 10 ft, 19 ft and 20 ft, it's probable that the instructions say to calculate the volume. That would be
V = (10 ft)(19 ft)(20 ft) = 3800 cubic feet.
