Mathematics
1 answer:
Drupady [299]3 years ago
3 0

Answer:

40

Step-by-step explanation:

angles QPR and RPS are complimentary, so they equal 90, or angle QPS, so you can set up the equations like so:

7x - 9 + 4x + 22 = 90

Combine like terms:

11x + 13 = 90

Subtract 13 from each side:

11x = 77

Divide each side by 11:

x=7

Then use this value in the angle that you are finding:

7(7) - 9

49 - 9

40

40 is your answer

Hope this helps!

An atom has 24 protons and 12 neutrons what is the chemical symbol for the atom?
kykrilka [37]

<u>Answer:</u>

The element is Chromium.

<u>Explanation:</u>

The atom has 24 protons and 12 neutrons.

We know that Cr has 24 number of protons, to the Chemical is Cr (Chromium)

Again, we know that the atomic number is the number of protons and the atomic mass is the sum of proton and neutron.

So, the atomic number is 24 and the atomic mass is (24+12)= 36

Therefore, the symbol is \bold^{36} \mathrm{Cr}_{24}\bold

AREA ADDITION AND SUBTRACTION ASSISTANCE?
Tom [10]

The shaded area is a segment. The area of a segment is

A_{segment}=A_{sector}-A_{triangle}.

You know radius that is the side of isosceles triangle and measure of angle between two equal triangle sides, then

A_{triangle} =\dfrac{1}{2} a\cdot a \sin \alpha=\dfrac{1}{2} 18.6\cdot 18.6 \cdot  \sin 123^{\circ}=172.98\cdot  \sin 123^{\circ}=145.07 sq. m..

The area of sector is A_{sector}=\dfrac{r^2\cdot \alpha}{2}= \dfrac{(18.6)^2\cdot 0.68\pi}{2}=117.63\pi=369.53 sq. m..

Then A_{segment}=369.53-145.07=224.46 sq. m.

Answer: A_{segment}=224.46 sq. m.
