Answer:
The number of people who owned computers last year was 1500.
Step-by-step explanation:
The information provided is as follows:
- The number of people who own computer in a small town is 2400.
- This is 60% more than the number who owned computer last year.
Let <em>X</em> denote the number of people who owned computer last year.
And <em>Y</em> denote the number of people who owned computer this year.
Then:
Y = X × (100% + 60%)
Thus, the number of people who owned computers last year was 1500.
Step-by-step explanation:
we have a rectangle, that is then cut in half diagonally into 2 right-angled triangles.
in our problem it does not matter which side is the larger and which is the shorter one, because the distance calculation for both cases involve one short and one long side. the sequence does not matter.
Mary walks one short and one large side to get to the opposite corner (from D to F) :
264 + 900 = 1,164 ft
Kate walks diagonally. and that diagonal is the Hypotenuse of the right-angled triangle with a short and a long side of the rectangle.
so, Pythagoras applies :
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90° angle), and a and b are the legs.
in our case that means
diagonal² = 264² + 900² = 69,696 + 810,000 =
= 879,696
diagonal = sqrt(879,696) = 937.9211054... ft ≈ 938 ft
so, Kate walked
1,164 - 938 = 226 ft
less than Mary.
Answer:
e. 36 inches
Step-by-step explanation:
there are 12 inches in a foot 3 times 12 is 36
In 9 different ways.
There will be 3 people left and 3 horses, and just multiply 3•3.
Answer:
8
Step-by-step explanation:
Notice:
32 = (8 x 4)
72 = (8 x 9)
Hence,
32 + 72
= (8 x 4) + (8 x 9) (factorize out the 8)
= 8 x (4 + 9)
therefore the musing number is 8
