Answer:

140

Step-by-step explanation:

P: parenthesis

E: exponents

M: multiply

D: Division

A: add

S: subtract

150-(4^2+4)/2 exponent first 4^2= 4*4=16 you do this because it is

inside the parenthesis

150-(16+4)/2 you still have parenthesis so solve that next

150-20/2 next you divide because there is no multiplication

150-10 then subtract because there is no addition

140 is your final answer

QUESTIONS The average price of wheat per metric ton in 2012 was $30575. Demand in millions of metric tons) in 2012 was 672. The

soldi70 [24.7K]

Answer: -0.9 ; inelastic

Explanation:

Given:

The average price of wheat per metric ton in 2012 = $305.75

Demand (in millions of metric tons) in 2012 = 672

The average price of wheat per metric ton in 2013 = $291.56

Demand (in millions of metric tons) in 2013 = 700

We will compute the elasticity using the following formula:

ε = $\frac{\frac{(Q_{2} - Q_{1})}{\frac{(Q_{2} +Q_{1})}{2}}}{\frac{(P_{2} - P_{1})}{\frac{(P_{2} +P_{1})}{2}}}$

ε = $\frac{\Delta Q}{\Delta P}$

Now , we'll first compute $\Delta Q$

i.e. $\frac{\Delta Q}{\Delta P}$ = $\frac{(700 - 672)}{\frac{(700 +672)}{2}}$

$\Delta Q$ = 0.04081

Similarly for $\Delta P$

i.e. $\Delta P$ = $\frac{(291.56 - 305.75)}{\frac{(261.56 +305.75)}{2}}$

$\Delta P$ = -0.0475

ε = $\frac{0.04081}{-0.0475}$

ε = -0.859 $\simeq$ -0.9

$\because$ we know that ;

If, ε > 1 ⇒ Elastic

ε < 1 ⇒ Inelastic

ε = 1 ⇒ unit elastic

$\because$ Here , ε = -0.859 $\simeq$ -0.9

Therefore ε is inelastic.

Tom used 5/8 yard of ribbon to tie weights on the tail of his kite. He cut the length of ribbon in equal pieces that were 1/12 y

sweet [91]

Here is the solution for the given problem above:
Given: 5/8 yard of ribbon = total length of the ribbon
1/12 yard = length of the ribbon after Tom cut it equally
? = number of pieces of 1/12 yard from 5/8 yard
So to divide fractions, here is the solution
5/8 divided by 1/12
5/8 multiplied by 12/1
5x12 is 60
8x1 is 8.
So 60/8 would be 7.5. Therefore, the number of pieces that was cut from the 5/8 ribbon is 7.5. Hope this answer helps.
