Answer:
x = 1.25, y = 1.75
Step-by-step explanation:
The smaller and larger triangles are similar triangles. (the 2 triangles have the same angles).
We know that the smaller triangle has length 8 for it's bottom side when the larger triangle has length 10. This means the scale factor between the 2 is 10 / 8 which is 1.25. Therefore by multiplying the side lengths of the smaller triangle by 1.25 we get the side lengths of the larger triangle.
5 * 1.25 = 6.25
7 * 1.25 = 8.75
However we don't want the whole side lengths we want x and y, We need to subtract 5 and 7 respectively from the lengths of the larger triangles.
Therefore the lengths must be: 6.25 - 5 = 1.25
and 8.75 - 7 = 1.75
Therefore x and y equal 1.25 and 1.75

To solve this, we make use of:
Where k is the constant of proportionality.
Solve for x
<u>Testing the given options</u>
A) (4,1)
B) (8,12)
C) (12,3)
D) (20,5)
E) (12,6)
In the number 4,586,909, the 6 is in the 4th place to the left of the decimal point which is the thousands place.
For a six to be 100 times more than in the thousands place, it must be in the hundred-thousands place. That is the 6th place to the left of the decimal point.
The answers are B. and D.

Answer:
B
Step-by-step explanation:
a is base edge
h is height or To find the volume of a square-based pyramid, use the formula V = A(h/3), where V is the volume and A is the area of the base.
