When it says that it needs to be cut, it means to divide. therefore, you divide the 30 foot pipe by 2/3. Dividing by 2/3 is the same as multiplying by 3/2. 30*30/2 would be the equation. Then you multiply 30 by 30. 90. Then you divide 90 by 2, which is 45.

Day Drive 270 miles and 6 hours how many miles do you drive in 13 hours ​
NikAS [45]

Answer:

The answer is

<h2>585 miles</h2>

Step-by-step explanation:

In order to solve this question we use ratio and proportion

From the question

Day Drive 270 miles in 6 hours

So in order to find the distance drove in 13 hours, we compare the distance drove in 6 hours to the distance drove in 13 hours and solve

That's

if in 6 hours Day drove 270 miles

Then in 13 hours the person will drive

\frac{13  \times 270}{6}  =  \frac{3510}{6}

We have the final answer as

<h3>585 miles</h3>

Find the length of the missing side
faltersainse [42]

Answer:

c = 17

Step-by-step explanation:

Since this is a right angle triangle we can use the Pythagoras theorem that states that c^{2} = a^{2} + b^{2} (where c is the Solve for  hypotenuse and "a" and "b" are the legs of the right angle triangle). From here we know that the answer to this question is....

c^{2} = a^{2} + b^{2}\\c^{2} = 15^{2} + 8^{2} \\c^{2} = 225 + 64\\c^{2} = 289\\c = \sqrt{289} \\c = 17

What’s measure of angle C?
Oduvanchick [21]
The angle is 60° because
B is a right angle and that adds to 90°, so dividing 90 by 3 would get 30

30 x 2 = 60

and to check the answer

x = 30

A=30
B=90
C=60

this adds to 180 which is correct because the angles in a triangle add to 180° :)
