A triangle with sides of lengths 9, 22, and 24 is a right triangle

Leona [35]

Answer:

The statement is false

Step-by-step explanation:

we know that

if the triangle is a right triangle

then

the triangle must satisfy the Pythagoras Theorem

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

we have

$c=24\ units$

$a=9\ units$

$b=22\ units$

substitute

$24^{2}=9^{2}+22^{2}$

$576=81+484$

$576 \neq 565$

therefore

Is not a right triangle

The statement is false

What is the frequency of yellow

Zina [86]

Answer:

5.131 × 10¹⁴ Hz

Step-by-step explanation:

<u>Planck relation</u>

$\large\boxed{E = hf}$

where:

E = Energy of the photon (J).
h = Planck's constant (J · s).
f = frequency of light produced (Hz).

Given values:

E = 3.4 × 10⁻¹⁹ J
h = 6.626 × 10⁻³⁴ J · s

Substitute the given values into the formula and solve for f:

$\implies 3.4 \times 10^{-19}=(6.626 \times 10^{-34})f$

$\implies f=\dfrac{3.4 \times 10^{-19}}{6.626 \times 10^{-34}}$

$\implies f=\dfrac{3.4}{6.626} \times \dfrac{10^{-19}}{10^{-34}}$

$\implies f=0.5131\times 10^{(-19-(-34))}$

$\implies f=0.5131 \times 10^{15}$

$\implies f=5.131 \times 10^{14}$

Say there are 2 candles per every 20 cakes. How many candles would there be for every 60 cakes?

abruzzese [7]

Answer:

There would be 6 candles.

Step-by-step explanation:

So you said that there would be 2 candles per 20 cakes, so I simplified it to 1 candle per 10 cakes. So, if there were 60 cakes, there would be 6 candles.

I hope it helped!
