Vertex = (3, - 2) this should be your answer. dm if im wrong
The answer is 42487 and it was very complicated
Slot method
20 options
3 slots
First slot: 20 options
Second slot: 19 options (one used up for 1st slot)
Third slot: 18 (one less than last)
Multiply them
20 times 19 times 18=6840
Answer is 6840 ways
Answer:
7 1/17
Step-by-step explanation:
A figure can be helpful.
The inscribed semicircle has its center at the midpoint of th base. It is tangent to the side of the isosceles triangle, so a radius makes a 90° angle there.
The long side of the isosceles triangle can be found from the Pythagorean theorem to be ...
BC² = BD² +CD²
BC² = 8² +15² = 289
BC = √289 = 17
The radius mentioned (DE) creates right triangles that are similar to ∆BCD. In particular, we have ...
(long side)/(hypotenuse) = DE/BD = CD/BC
DE = BD·CD/BC = 8·15/17
DE = 7 1/17 ≈ 7.059
Answer:
36
Step-by-step explanation:
Okay! This question is a very simple one, but without a calculator, your answer could easily vary from others! So, let´s do this one together!
The equation:
0.810x0.00048/0.000400x0.027
Let´s do the top :
0.810 x 0.00048 = 0.0003888
I will leave these numbers the same until the last part, lets not round them.
Bottom:
0.0004 x 0.027 = 0.0000108
And again I am not going to round this number.
Now we can divide!
0.0003888/0.0000108 = 36
I hope this helped!
