If you would like to find the volume here:
L•W•H
Big Rectangular: 10•14•6
Small Rectangular: 1•2•3
Surface Area:
2(L•W) + 2(L•H) + 2(W•H)
Big Rectangular: 2(10•14) + 2(10•6) + 2(14•6)
Small Rectangular: 2(1•2) + 2(1•3) + 2(2•3)
Because the shape is not undergoing a dilation, the perimeter of the original image and the new image is the same. The only thing that is changing is the placement of the original figure.
I hope this helps! :)
Answer:
They make 4 approximately tons of oxygen each year.
Step-by-step explanation:
( 250lbs × 32 ) ÷ 2000 = 4t
250 pounds because each tree makes about 250 pounds of oxygen a year.
× 32 because there are 32 trees, so they'll make 32 times more oxygen than one tree.
÷ 2000 because before that everything was in pounds, and the question asks about tons. There are 2000 pounds in a ton, so you divide by 2000 to get the answer, which is 4 tons.
All of a triangles angles add up to 180, this is known as the triangle sum conjecture.
an Iscoceles triangle is a triangle that has two or more congruent sides.
if a triangle is Iscoceles then th e two angles that are made by the congruent sides and base are also congruent.
if you know that one of the angles is 20 that. The sum of the other two angles must be 160.
That means that answer 2 and 4 are incorrect.
Answers 1 and 3 both have a total angle sum of 160. since this is true the correct answer depends on where the known angle is. If it is the angle that is formed by the two congruent sides than the answer is number one. but if it is formed by one of the congruent sides and the base then the answer is number 3.
