Answer:

Yes

Step-by-step explanation:

3\frac{1}{6} + 5\frac{7}{8}

When adding two fractions, both denominators must be the same

To do this, multiply 3\frac{1}{6} by 4 to make it into 3\frac{4}{24}

And multiply 5\frac{7}{8} by 3 to turn it into 5\frac{21}{24}

The new equation is:

3\frac{4}{24} + 5\frac{21}{24} = 8\frac{25}{24}

Since you can make a whole number from \frac{25}{24}, the number 8 becomes a 9

and the new answers becomes 9\frac{1}{24}

An aircraft factory manufactures airplane engines. The unit cost (the cost in dollars to make each airplane engine) depends on t
Juliette [100K]

Answer:

Minimum unit cost = 5,858

Step-by-step explanation:

Given the function : C(x)=x^2−520x+73458

To find the minimum unit cost :

Take the derivative of C(x) with respect to x

dC/dx = 2x - 520

Set = 0

2x - 520

2x = 520

x = 260

To minimize unit cost, 260 engines must be produced

Hence, minimum unit cost will be :

C(x)=x^2−520x+73458

Put x = 260

C(260) = 260^2−520(260) + 73458

= 5,858

Can you please give the answer for this problem? :<br> 18+11v=w-13t for t
Kay [80]
18+11v=w-13t
18+11-w=-13t
13t=w-11v-18
t=1/13w - 11/13v - 1 5/13

Hope this helps :)
