Answer:
DOG = 270
Step-by-step explanation:
270 × 3 = 810
_____
The only numbers that end in the same digit when multiplied by 3 are 0 and 5.
0×3 = 0
5×3 = 15
If G is 5, then you are looking for digits DO than give a product of 80 when multiplied by 3. 80 is not divisible by 3, so that doesn't work.
G must be 0.
Then the product of DO and 3 is 81, so DO = 81/3 = 27.
The solution is ...
D = 2
O = 7
G = 0
Answer:
20 books
Step-by-step explanation:
Height of stack = 35 inches
Thickness of one book
No. of books

It would just be 80. They are both in the bottom right and I'm guessing this is one the problems that look like this:
-------/------
-----/--------
So just think about it. If the line is a straight line through two parallel lines then the angles of the two intersections should be the same. Basically because they are both on the bottom right they will be the same. Glad to help!
Answer:
see below
a = 0.66...
b = 0.73
c = 7/8
Step-by-step explanation:
The first two numbers, 0.73 and 0.667, are near the point that is halfway between 0.6 and 0.8. That halfway point is 0.7. The value 0.667 will be below (left) of the halfway point, so is point <em>a</em>. The value 0.73 will be above (right) of the halfway point, so is point <em>b</em>. The remaining value, 7/8, must be point <em>c</em>.
__
You may know that 7/8 = 0.875, so is nearly halfway between 0.8 and 1.
_____
The attached graph has the points color-coded.
_____
Of course you know that the overline in
indicates that digit repeats indefinitely. The value 0.667 is the number rounded to 3 decimal places.
