By the traingle sum theorem, the sum of the angles in a triangle is 180°. Therefore, using the given and triangle sum theorem, m(∡P) + m(∡Q) + m(∡R) = 180°.

(5x)° + (5x)° + (8x)° = 180°. Simplifying the equation gets 18x=180°. Finally, using the division property of equality, x=10°.

Can someone help me with this pls?

Pavlova-9 [17]

Answer:

1176 $cm^{3}$

Step-by-step explanation:

First, calculate the volume as if it was a full rectangle.

Volume formula:

length x width x height

16 x 6 x 21 = 2016 $cm^{3}$ (this is the volume if this was a full rectangle)

Now to calculate the size of the missing part we do the same thing

10 x 6 x 14 = 840 $cm^{3}$

To work out the volume of this shape, we need to subtract the volume of the missing part from the volume of the rectangle

2016 - 840 = 1176 $cm^{3}$

I hope this helped :-)

Your middle school has 900 students. 1/3 of students bring their lunch instead of buying lunch at school. What is the value of t

Sholpan [36]

Hey there!
This may seem pretty scary because, duh, fractions, big numbers, MATH.
However, you've just got to break it down.
So first, we find out how many students BRING lunch.
To find 1/3 of 900, you just multiply 900 by 1/3. $\frac{900}{1} * \frac{1}{3}$
BUT WE CAN SIMPLIFY: to 300/1 times 1/1, which is 300/1.
So 300 people BRING lunch.
Now, to find people who BUY lunch, you just subtract the number of people who bring lunch by the total number of people.
900
-300
600
So 600 people BUY lunch.
All that's left to do is turn all these numbers into a ratio.
Easy peasy: put 300 and 600 like a fraction, like so:
$\frac{300}{600}$
Hope this helped! ;)
