Answer:
25.2
Step-by-step explanation:
A calculator will evaluate this for you. If you don't have one, you can use a Google search box.
The Order of Operations tells you to start evaluation with the inner parentheses. Multiplication is performed before addition.
2(7 +2(2.8))
= 2(7 +5.6)
= 2(12.6)
= 25.2
Step-by-step explanation:
When you reflect a point across the y-axis, the x-coordinate gets multiplied by -1 and the y-coordinate remains the same.
A(-3, -2) => B(3, -2).
The number that is filled in the blank is 3.
You do this 35*x=21. and x is the percent. x=0.6. 0.6 is 60 percent. So 21 is 60 percent less than 35.
Answer:
Area rhombus = 110
Step-by-step explanation:
The diagonals of a rhombus intersect at right angles.
They bisect each other.
So the diagonals form 4 right angle triangles whose legs are 1/2 of each of them.
Leg of 1 triangle = 1/2 * 10 = 5
Other leg of 1 triangle = 1/2 * 22 = 11
Area of 1 triangle = (1/2 ) * 5 * 11 = 1/2 * 55 = 27.5
Area of all 4 triangles = 4 * 27.5
Area of all 4 triangles = 110
Area of rhombus = 110
Answer:
C 176 square centimeters.
Step-by-step explanation:
(20×4)+(16×6)
it's the area of each part added together.
