Answer:
18
Step-by-step explanation:
make a ratio relation:
3 trainers : 12 dogs
x trainers : 72 dogs
3/12 = x/72
solve for x, and you get 18
To decompose a fraction to one whole, there are different methods to use. The fraction can be decomposed either by division, multiplication(if there are more than one fraction), or addition(if there are more than one fractions).
Example:
Given 8/2, decompose by division:
To do this, divide the numerator by denominator
Answer:
(-2,-3)
Step-by-step explanation:
Since there is a point P including coordinates (-1,5) and it is shown on a horizontal line i.e y =1
Now we have to compute the new coordinates of P
If a point is mirrored along a horizontal line, only vertical distance varies, however the horizontal distance is still the same, i.e. from y axis or x coordinate.
Therefore new x coordinate = -1
As P has 4 distance from the line y =1
Therefore P' will also contains a distance of 4 on the other side of y = 1
i.e. y coordinates could be
= 1 - 4
= -3
hence, the new coordinate is (-2,-3)
So a dime is .10 or 10 cents
a quarter is .25 or 25 cents
12(.10)=$1.2
4(.25)=1
the equations would be
.25(x)
.10(x)
and if you need them combined it would be
.25(x) + .10(x)

Answer:
=42
Step-by-step explanation:
The expression 8×7×9×49×3 can be written in its simplest factor form as follows.
8=2³
49=7²
9=3²
Thus the expression becomes:2³×7×3²×7²×3
Combine the indices to the same base.
2³×3³×7³
Finding the cube root involves dividing the index by three.
Thus ∛(2³×3³×7³)= 2×3×7
=42
