Answer:
81/42
Step-by-step explanation:
8 1/10 ÷ 4 1/5
81/10 ÷ 21/5
81/10 * 5/21
(81*5)/(10*21)
405/210
81/42
Answer: $5400
im assuming you want the total cost?
4000+1400=5400
Answer:
- f¯¹(x) =9x+18, for the pictorial(image) question
- what is the send question is it asking derivative or inverse
- If it is inverse f¯¹(x)=-x-2 as it is
- Or if it is derivative f'(x)=-1
Step-by-step explanation:
<h2>
For the image question f(x)=1/9x-2,f¯¹(x)=?</h2>
- f(x)=1/9x-2............given
- y=1/9x-2................swapping f(x) by y to Easily write
- x=1/9y-2................interchanging x and y
- 1/9y-2=x................changeling side of equation
- 9(1/9y-2)=(x)9.......multiplying both sides by 9 to override the fraction on the right side
- y-18=9x
- y=9x-18.................Return to where it were
- <em><u>f¯¹(x)=9x+18</u></em>..........swap back f¯¹(x) in the y
<h2>
For the question f(x)=-x-2,f¯¹(x)=?</h2>
- following the ☝️ arrangement
- y=-x-2
- x=-y-2
- -y-2=x
- -y=x+2
- y=-x-2
- f¯¹(x)=-x-2
Answer: 0.25
<u>Step-by-step explanation:</u>
You need to convert the cm³ into m³

= .25 m³ per m²
Answer:
$75000/year
$6250/month
Step-by-step explanation:
1500 ft²*$50/(ft²*year) = $75000/year
1 year = 12 month
$75000/12 month= $6250/month
