Answer:

168 minutes or 2 hrs. 48 minutes

Step-by-step explanation:

The first part of the problem is just stating that x and y are proportional. This means that Beau goes a certain amount of miles for every minute. One way to solve this problem is to find out how much the constant of proportionality is (finding out how long 1 mile would take), and then multiplying that by 8. The other but easier way (according to me) is to make an equation. The proportional equation you have to make is:

5 miles/ 105 minute

8 miles/ x minutes

In this situation, x is the unknown amount of minutes it would take Beau to ride is his canoe for 8 miles.

Then you cross multiply, getting 5x = 105*8.

Next, you multiply 105 by 8 to get 840.

Lastly, divide that by 5 to get 168 minutes.

Here are 2 handy dandy methods to solve proportionality-typed problems.

Simplify square root of five times square root of eight.
kipiarov [429]

Answer:

1. two square root of ten

Step-by-step explanation:

Given expression is:

\[\sqrt{5}* \sqrt{8}\]

Simplifying the expression:

\[\sqrt{5}* \sqrt{4 \ast 2}\]

= \[\sqrt{5}* \sqrt{4}*\sqrt{2}\]

= \[\sqrt{5}* 2*\sqrt{2}\]

= \[2 * \sqrt{5} * \sqrt{2}\]

= \[2 * \sqrt{10}\]

So among the given options, option 1 is the correct one,namely, two square root of ten.

The swimming pool is open when the high temperature is higher than 20^\circ\text{C}20 ? C20, degree, C. Lainey tried to swim on
Svetlanka [38]

Answer:

30-3d\leq 20

Step by step explanation:

Let d represent the rate of temperature decrease in degrees Celsius per day from Monday to Thursday.  

As temperature decreased at a constant rate in the next 3 days, so the rate of temperature will decrease 3d degree Celsius in 3 days.  

We are told that the pool was open on Monday. The high temperature was 30^{\circ}{\text{C} on Monday. So the decrease in temperature from Monday to Thursday will be 30-3d.

We have been given that the swimming pool is open when the high temperature is higher than 20^{\circ}{\text{C}.

As the pool was closed on Thursday. This means that temperature on Thursday was less than or equal to 20 degree Celsius. We can represent this information in an inequality as:

30-3d\leq 20

Therefore, the inequality 30-3d\leq 20 can be used to determine the rate of temperature decrease in degrees Celsius per day, d, from Monday to Thursday.
