-5=y
Answer:
If the interior angles of quadrilaterals STUV and WXYZ are equal then the quadrilaterals, STUV and WXYZ were similar.
Step-by-step explanation:
Quadrilaterals are polygons with four sides.
Similar polygons are in identical form, but can be variant magnitudes.
Two polygons can be considered as similar if the following two things are accurate:
1. The corresponding sides of each polygon are in the same proportion
2. The corresponding interior angles are the equal (congruent).
So, if the interior angles of quadrilaterals STUV and WXYZ are equal then the quadrilaterals, STUV and WXYZ were similar.
Answer:
75 seconds
Step-by-step explanation:
Here, we want to get her time 6 weeks ago.
We shall have an exponential model to link this all up
The exponential model would look like;
y = I(1 - r)^n
where y is the present time
I is the initial time she started with which we are calculating
r is the rate of change which is 2% = 2/100 = 0.02
n is the week number which is 6 in this case
So we have;
66 = I(1 - 0.02)^6
66 = I(0.98)^6
I = 66/0.8858
I = 74.5 seconds
This is approximately 75 seconds
Her time 6 weeks ago is 75 seconds
Answer:
B) 686 cubic units
Step-by-step explanation:
If one cube has a side length of 7, then it equals to 343 cubic units. Since there are 2 cubes, this translates to 686 cubic units.
