Answer:

1/8.

Step-by-step explanation:

The probability of of a head (and a tail) in one toss of a coin being obtained is 1/2.

Each toss is independent of the others so we multiply the probabilities.

So Prob(Head - tail - head) = 1/2*1/2*1/2 = 1/8.

Answer:

$\boxed{\boxed{\pink{\bf \leadsto It \ will \ take \ 5 hours \ to \ travel \ 300 \ miles. }}}$

<h3>Step-by-step explanation:</h3>

According to Question , a plane travels 120 miles in 2 hours. So here we will use unitary method .

$\bf\implies If \ it \ covers \ 120 \ miles \ in \ 2 \ hours \\\\\bf\implies Then \ one \ mile \ will \ be \ covered \ in \ \dfrac{120}{2} hrs \\\\\bf\implies Hence \ 300 \ miles \ will \ be \ covered \ in \ \dfrac{2}{120}\times 300 hrs = \red{5 \ hours }$

<h3>Hence it will cover 300 miles in 5 hours .</h3>

Here it was a case of direct proportion in which if two things are directly proportional to each other. If one thing thing increases then the value of second also increases. Here if the time increases then the distance also increases

A small bottle of water holds 7 ounces of water. How many ounces of water do 9 bottles hold?

White raven [17]

Step 1

Given;

$A\text{ small bottle of water holds 7 ounces of water}$

Required; How many ounces of water do 9 bottles hold?

Step 2

To do this we will use the ratio;

$\frac{1\text{ bottle}}{9\text{ bottles}}=\frac{7\text{ ounces}}{x}$ $\begin{gathered} x=7(9) \\ x=63\text{ ounces} \end{gathered}$

Answer;

$9\text{ bottles of water holds 63 ounces}$

Answer:

Dear Laura Ramirez

Answer to your query is provided below

Option B is correct

Step-by-step explanation:

In a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.

Also,

By the triangle inequality theorem, the sum of the lengths of any two sides should be greater than the length of the third side.

Here, if you see( 16+24)>38

So, the set of numbers can be measures of a

triangle.

HELPPPPP Find the missing parts of the triangle. Round to the nearest tenth when necessary or to the nearest minute as appropria

The missing parts of the triangle ABC are A = 31.4°, B = 57.4°, C = 91.2°

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that a = 8.6 in, b = 13.9 in. and c = 16.5 in. Using cosine rule:

c² = a² + b² - 2abcosC

16.5² = 8.6² + 13.9² - 2(8.6)(13.9) * cosC

C = 91.2°

Also:

a² = b² + c² - 2bccosA

8.6² = 16.5² + 13.9² - 2(16.5)(13.9) * cosA

A = 31.4°

A + B + C = 180° (angles in a triangle)

31.4 + B + 91.2 = 180

B = 57.4°

The missing parts of the triangle ABC are A = 31.4°, B = 57.4°, C = 91.2°

The aquarium has a scale model of a great white shark for sale in their gift shop. If the scale of the model is 2 in. : 7 ft, wh

kompoz [17]

Answer:

14ft

Step-by-step explanation:

Since the scale is 2in : 7ft, so you would do 7x2 which gets you to 14.

(You would do 7x2 because 4 in/2 in = 2in, that's where the 2 comes from, and 7 because 7ft is part of the scale.)

Hope this helps :D
