A cyclist must travel 800 km. how many days will the trip take if the cyclist travels 8 h/day at an average speed of 16 km/h?

1 answer:

7 0

First, you need to find out how much the cyclist will travel a single day. Since the cyclist travels 16 km/h and for 8 h/day, you can easily multiply 16 x 8 = which would be 128 km/day.

To find how long it will take the cyclist to travel 800km, just divide 800 by the amount they will be going in one day. 800/128= 6.25. That would convert to 6 days and 6 hours.

You'll obviously have to convert "million pounds" to "tons."
Hint: 1 ton = 2000 pounds. Create a conversion factor from this and then multiply "3.5 million pounds" by your conversion factor (with "pounds" in the denominator of this factor).

What are the missing angle measures in triangle ABC?

Finger [1]

we know that

In the right triangle ABC

∠ $A+$ ∠ $B=90$ ------> by complementary angles

Step $1$

Find the measure of angle B

we know that

$tan\ B=\frac{opposite\ side\ angle\ B}{adjacent\ side\ angle\ B}$

in this problem

$opposite\ side\ angle\ B=7in\\ adjacent\ side\ angle\ B=5in$

$tan\ B=\frac{7}{5} \\ \\ B=arc\ tan\frac{7}{5} \\ \\ B=54.5\ degrees$

Step $2$

Find the measure of angle A

$A+B=90\\ A=90-B\\ A=90-54.5\\ A=35.5\ degrees$

therefore

the answer is the option

35.5° and 54.5°

Answer:

(a)The amount of fuel in dollars = $1.62

(b)The rate equivalent to in U.S. dollars per gallon = $ 1.45

Step-by-step explanation:

Reid will be driving through Spain this summer. He did some research and knows that the average price of gas in Spain is approximately 1.12 euros per liter.

1 USD = 0.69 euros

We have to find the money that we should pay in order to get the same amount of fuel.

1 euro = $\frac{1}{0.69}$

1 euro = $1.45

So 1.12 euros = 1.12 $\times$ 1.45 = $1.62

(a)The amount of fuel in dollars = $1.62

(b)The rate equivalent to in U.S. dollars per gallon = $ 1.45
