Rates for having a manuscript typed at a certain typing service are $5 per page for the first time a page is typed and $3 per pa

Goryan [66]

Answer:

D. $680

Step By Step Explanation:

100 pages are typed. Each page coast $5 to type.

100 x 5 = 500

40 pages are revised once. It costs $3 to revise a page once.

40 x 3 = 120

10 pages are revised twice. It costs $3 to revise a page once so it will cost $6 to revise it twice

10 x 6 = 60

To find the total cost we add all the amounts together

500 + 120 + 60 = 680

The final answer is $680

If a 100 m. diameter wind turbine is exposed to 7 m/s wind with an air density of 1.25 kg/m what is the electricity produced by

Yuliya22 [10]

Answer:

electric energy = 980 J

Step-by-step explanation:

Given,

Diameter of wind turbine = 100 m

Speed of wind,v = 7 m/s

Density of air = 1.25 kg/m

Hence, the total mass of air enters into turbine =Speed of wind x Diameter of wind turbine

= 1.25 x 100

= 125 kg

Hence, total mechanical energy of turbine can be given by,

$E\ =\ \dfrac{1}{2}.m.v^2$

$=\ \dfrac{1}{2}\times 125\times 7^2$

= 3062.5 J

Efficiency of turbine = 32%

Hence,

total electric energy = 32% of mechanical energy

$=\dfrac{32}{100}\times 3062.5\ J$

= 980 J

So, the total electric energy produced by the turbine will be 980 J.

A container has 20 12 cups of pancake mix. A serving uses exactly 2 ) cups.

just olya [345]

Answer:

10 full servings and $\frac{1}{4}$ cups leftover

Step-by-step explanation:

Our container has a total of 20 and a half cups. And each full serving is 2 cups.

So, we divide $\frac{20\frac{1}{2} }{2}$ .

To do this manually, we convert the numerator into an improper fraction: $\frac{\frac{41}{2} }{2}$ .

Now, we multiply the denominators: $\frac{41}{4}$ .

This will give us $10\frac{1}{4}$ servings. So we only have 10 full servings.

There are $\frac{1}{4}$ cups leftover.
