What is the length of the hypotenuse of a right triangle with side that measure 7 cm and 24 cm

elixir [45]

To find our answer, we are going to use the Pythagorean Theorem, which states:

$a^2 + b^2 = c^2$

for a right triangle with sides $a$ , $b$ , and $c$ where $a$ and $b$ are the legs and $c$ is the hypotenuse.

Based on the information given in the problem, we can say $a = 7$ and $b = 24$ . When we use this information in our formula, we can find $c$ :

$7^2 + 24^2 = c^2$

$625 = c^2$

$\boxed{25 = c}$

Our answer is B, 25.

To mix plaster for a dental model, 35 mL of water is used for 100g of plaster. How many mL of water should be used for 250g of p

laila [671]

Okay, here we have this:

Considering the provided information, we are going to calculate the requested value, so we obtain the following rule of three:

$\begin{gathered} \frac{x}{35mL\text{ of water}}=\frac{250g\text{ of plaster}}{100g\text{ of plaster}} \\ x=\frac{250g\text{ of plaster}}{100g\text{ of plaster}}\cdot35mL\text{ of water} \end{gathered}$

Solving for x:

$\begin{gathered} x=2.5\cdot35mL\text{ of water} \\ x=87.5mL\text{ of water} \end{gathered}$

Finally we obtain that 87.5mL of water should be used for 250g of plaster.
