Answer:
b = 21
Step-by-step explanation:
By the Pythagorean Theorem, which states that if you have a right angle with legs of a and b, and a hypotenuse of c, then a^2+b^2=c^2. Use this on the right triangle in the diagram to get 841 = 400 + b^2, or 441 = b^2 and b = 21.
Note: I think that the 1st diagram was unnecessary. ;)
Answer:
2000000 bricks
Step-by-step explanation:
The computation of the number of bricks to be used is shown below:
The Volume of brick is
= (15 × 8 × 5)cm^3
= 600 cm^3
And, the Volume of wall is
= (1500 × 1000 × 800)cm^3
= 1200000000 cm^3
Now Bricks needed is
= 1200000000 cm^3 ÷ 600cm^3
= 2000000 bricks
Answer:
4 square root 2
Step-by-step explanation:
the pythagorian theorem will look like this: 2^2+b^2=6^2
simpify: 4+b^2=36
get b by itself by subtracting four from each side: b^2=32
take the square root of 32 and simplify: 4sqrt2
Answer:
200
Step-by-step explanation:
The ratios is 5 to 2 - so if you divide 500/5 = 100 then multiply 2 * 100 (the same rate) to keep the ration intact.
