I'm almost sure you left your phone in the restaurant.

Tcecarenko [31]

The best way to complete the second sentence such that it resembles the one given is "You <u>must have </u>left your phone in the restaurant."

<h3>Reason for using "must have"</h3>

Using the phrase, "almost certain" infers that a person has little doubt that something has happened.
The phrase, "must have" also infers little doubt and high probability.

The best phrase to fit in the second sentence that would both be grammatically correct and convey the same meaning, is therefore "must have."

In conclusion, the answer is "must have."

John bought 15 pines for $3500

Shalnov [3]

Answer:

Explanation:

If John needs to ensure a 40% profit, John needs to sell the pines at a price that would give 40% more money back than he spent.

Since John needs to make back all of the money he spent, plus another 40%, John needs to get back 140% of what he spent.

$140\% = 1.40$

John spent $3500.

140% of $3500 is $4900.

So, John must bring in $4900 (revenue) selling all 15 pines to achieve a 40% profit.

However, the question asks for the price of a single pine. To find the unit price of a single pine, divide the total revenue by 15.

$\frac{\$4900}{15pines}=\frac{\$326.\bar{6}}{pine}=\$326.66 \text{ per pine}$

Course 3 chapter 5 triangles and the pythagorean theorem

Galina-37 [17]

The pythagorean theorem is used to calculate the lengths of a right triangle

The hypotenuse of the triangle is 6.5 cm

<h3>How to determine the hypotenuse of the triangle?</h3>

From the complete question, we have the following side lengths

Opposite = 5.7 cm
Adjacent = 3.2 cm

The hypotenuse of the triangle is then calculated as:

Hypotenuse^2 = Opposite^2 + Adjacent^2

This gives

Hypotenuse^2 = 3.2^2 + 5.7^2

Evaluate the sum

Hypotenuse^2 = 42.73

Take the square root of both sides

Hypotenuse = 6.5

Hence, the hypotenuse of the triangle is 6.5 cm
