The Pythagorean theorem is the idea that the sum of the two legs which are both squared is equal to the hypotenuse's length squared.

*look at the image I attached for a better explanation

By looking at the picture, we are missing the leg's length, and by using the Pythagorean theorem, we get the equation

$?^2+9^2 = 16^2\\?^2 + 81 = 256\\?^2 = 175\\? = 13.2$

Thus the missing side length is 13.2 cm

Hope that helps!

After a 5% pay raise , Hermione is earning $21,000 per year. What was she earning before the pay raise?

Finger [1]

Answer:

$\$20,000$

Step-by-step explanation:

Let

x -----> Hermione was earning before the pay raise

we know that

$100\%+5\%=105\%=105/100=1.05$

The linear equation that represent this problem is

$1.05x=21,000$

Solve for x

Divide by 1.05 both sides

$x=21,000/1.05$

$x=\$20,000$

Solve the following equation. log Subscript 2 Baseline (3 x plus 7 )equals 5 The solution set is StartSet nothing EndSet . (Sim

tigry1 [53]

Answer: $x=\dfrac{25}{3}$

Step-by-step explanation:

The given equation : $\log_2(3x+7)=5$

Using logarithmic property : $\log_a N=M\to N=a^M$

The given equation will be equivalent to $(3x+7)=2^5$

$\Rightarrow\ 3x+7=32$

Subtract 7 from both sides , we get

$3x=25$

Divide both sides by 3 , we get

$x=\dfrac{25}{3}$

Hence, the solution is $x=\dfrac{25}{3}$

Simplify each expression. (giving 50 points and brainliest)

Kamila [148]

Answer:

See below

Step-by-step explanation:

$-[-(11-22)]=-[-(-11)]=-[11]= \large\boxed{-11}$

$\left( \frac{3}{2} \right) \cdot \left(-\frac{22}{33} \right) = -\frac{66}{66}=\large\boxed{-1}$

$\frac{4^2}{5^2}=\large\boxed{\frac{16}{25}}$

$-\frac{4}{3} -\frac{4}{13} = -\frac{4 \cdot 13}{3 \cdot 13} -\frac{4 \cdot 3}{13 \cdot 3} = -\frac{52}{39} -\frac{12}{39} = \large\boxed{-\frac{64}{39}}$

$\sqrt{\frac{27}{3} } =\sqrt{9} =\large\boxed{3}$

A woman that is 6 ft tall casts a shadow that is 18 ft long. Find the height of a car that casts a 12 ft shadow.

Westkost [7]

It should be 4 feet tall, because if the woman casts a shadow 3 times her height than a car with a 12 foot tall shadow should be four feet tall
