Estimate the product 33.6 x 82.1

1 answer:

7 0

I would just round the numbers and then multiply

33.6 rounded = 34
82.1 rounded = 82

So just multiply 34 by 82

34 x 82 = 2788

Hope that helps and correct me if I'm wrong!

Dana can type nearly 90 words per minute. Use this information to find the number of hours it will take her to type 2.6 x 105 wo

Vlad1618 [11]

Dana can type 90 words per minute.

Since, 1 minute = $\frac{1}{60}$ hours

Therefore, number of words she can type = $\frac{90}{\frac{1}{60}}$

= 90×60

= 5400 words per hour

If she types $2.6\times 10^5$ words in 'x' hours.

Number of words Dana types with the given speed in 'x' hours = Speed of typing × Time

= $5400\times x$

Therefore, $5400\times x =2.6\times 10^5$

$5400x=260000$

$x=\frac{260000}{5400}$

$x=48.15$ hours

Therefore, Dana types $2.6\times 10^5$ words in 48.15 hours.

Alexus [3.1K]

Answer: $110

Step-by-step explanation:

Given: At Simba Travel Agency, the price of a climbing trip to Mount Kilimanjaro includes an initial fee plus a constant fee per meter.

F(d)models the fee (in dollars) for climbing d meters.

$F(d)=110+0.12d$

To find the initial amount, substitute d=0 int the above function, we get

$F(0)=110+0.12(0)=110$

Hence, the initial fee= $110.
