Multiply 15000 by 0.8³ to get $7680
You get 0.8 because 100% minus 20% is 80% so you turn that into 0.8 and its 0.8³ because theres 3 years. Hope that made sense!
Answer:
A
Step-by-step explanation:
Given the 2 equations
4x + 5y = - 12 → (1)
- 2x + 3y = - 16 → (2)
Eliminate the x- term by multiplying (2) by 2 and adding the result to (1)
- 4x + 6y = - 32 → (3)
Add (1) and (3) term by term
11y = - 44 ( divide both sides by 11 )
y = - 4

Step-by-step explanation:
Answer:
57.72 in^2
Step-by-step explanation:
Question 1. Shapes are triangle, semi-circle, and rectangle.
Question 2.Find area of rectangle first. Then area of triangle and circle. Subtract area of triangle and circle. Then add the difference with the rectangles area.
Question 3.
Rectangle's area:<u>48 in^2</u>
Triangles area:8*4/2= <u>16 in^2</u>
Circle Area: pi*r^2/2(since its a semi-circle)
3.14*2^2=3.14*4=12.56/2=<u>6.28 in^2</u>
Question 4.
16-6.28=9.72
9.72+48=57.72 in^2
Hiiiii ^-^ I can help you XD
Congruent
The same shape and size.
Two shapes are congruent when you can Turn, Flip and/or Slide one so it fits exactly on the other.
In this example the shapes are congruent (you only need to flip one over and move it a little).
Angles are congruent when they are the same size (in degrees or radians).
Sides are congruent when they are the same length.
