Formula: length · width
2 big rectangles:96 + 96 = 192
(12 × 8) · 2
2 smaller rectangles: 72 + 72 = 144
(6 × 12) · 2
2 small rectangles: 48 + 48 = 96
(6 × 8) · 2
Add all 3 numbers:
192 + 144 + 96 = 432
Your answer is D. 432 cm²
Hope this helps :)
A=P(1+r/100)^n
A=500(1+4/400)^24
A=500(1.01)^24
A=634.87
Answer:
-21/32
Step-by-step explanation:
It's easier to do this multiplication mentally if we rewrite the expression as follows:
-3 7 -21
------ * ------ = ---------
4 8 32
Let's use Newton's Law of Universal Gravitation, which is expressed as<span>F=G<span><span><span>(m1</span><span>m2)/</span></span><span>r2</span></span></span>We can find the force of attraction between them. Then, to find the acceleration from<span>F=<span>m1</span><span>a1</span> <span>and</span> F=<span>m2</span><span>a2</span></span>I'll take it you know the equations of motion for constant acceleration. <span>y=<span>1/2</span>a<span>t^2</span></span>
Obviously, as they accelerate towards each other, the radius between
them decreases, meaning the force of gravitation between them increases,
meaning they accelerate faster.
Answer:
C
Step-by-step explanation:
A. Equilateral triangle is a triangle with all sides congruent. These triangles are not equilateral, because there is no information about all three sides of each triangle.
B. Isosceles triangle is a triangle with two sides congruent. These triangles are not isosceles, because there is no information about congruence of two sides of each triangle.
C. ASA posrulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent. This is exactly what you are given in this question, so this option is true.
D. This option is false, because triangles can have two pairs of congruent angles (for example, 20° and 40°), then third pair are also congruent angles not necessarily right (180°-20°-40°=120°≠90°).
