I think it would take an average of both the numbers so first find the average of 60 and 90 by adding and dividing by two. You will get 75 seconds. That is the answer

Determine whether the variation between the indicated quantities is direct or inverse. The number of calories in a cheese pizza
-BARSIC- [3]

Answer:

The variance is direct.

Step-by-step explanation:

Since size of the pizza determines the amount of calories.

Let us say that a 2" x4" strip of pizza has 250 calories.

Then a pizza of twice the size (or 4" x 4") will have twice as many calories (500 calories) .

Lydia wants to buy new boots that cost $130. She has saved 82% of what she needs to buy the boots. How much money has she saved
Lorico [155]

Answer:

Answer:

44 = 12 + M

Step-by-step explanation:

Start with your final amount that everything else is going to equal

44 =

Then, add the $12 that is already saved to the other side\

44 = 12

But, that equation is not true yet, so we have to add the amount of money that she still needs to save

44 = 12 + M

That equation shows that the money she has saved ($12), plus the amount she still has to save will equal the amount she needs.

Use a linear approximation (or differentials) to estimate the given number.
bagirrra123 [75]
Would use the algorithm for solving square root.

For square root,  √n

x₁ = 0.5(x₀ + n/x₀)        

(This formula is known and for square root, and can be derived using Newton-Raphson's approximation equation)

Where x₀ is the initial guess.  x₁ becomes the new guess.

For √100.6  let our initial guess be 10,  x₀ = 10,  n = 100.6

Our approximation shall be to 3 decimal places. Once we get the same answer twice we stop the algorithm.

x₀ = 10,  x₁ = 0.5(x₀ + n/x₀),    x₁ = 0.5(10 + 100.6/10)  = 10.030, x₁ = 10.030

x₂ = 0.5(x₁ + n/x₁),    x = 0.5(10.030 + 100.6/10.030)  ≈10.015,  x₂ ≈ 10.030 (to 3 decimal places)

Since x₂≈ x₁, the algorithm stops.

So the √100.6 is ≈ 10.030 to 3 decimal places.

I hope this helps.
