Answer:
702 i think
Step-by-step explanation:
13 x 6 x 9
Do 100 divided by 30 and it equals a decimal
Time used total: 50 hours.W+C = 50 (1) Total water used is 1900 L.Woody family used: 40W; Carter family used 35C.Equation showing how much water both families used:40W + 35 C =1900. (2) We have a system with two equations and two variables. We can use substitution method to solve the system. From equation (1) we express W:W=50 - C. (1a) We substitute the variable in equation (2):40(50 - C) +35C =1900. We open the parenthesis2000 -40C +35C =1900, We combine like terms2000 -5C =1900, We subtract 2000 from both sides of the equation-5C = 1900 - 2000, We simplify-5C = -100, We divide by -5C = 20. We substitute the values of C in the equation (1a) and find the value of W:W = 50 - C,W = 50 -20 =30. The Woody family used water for 30 hours and the Carter family used water for 20 hours.We check our work to be sure we did not make any mistakes:Total water used: 40 x 30 + 35 x 20 = 1200 + 700 = 1900 L.
Answer:
After a translation, the measures of the sides and angles on any triangle would be the same since translation only involves changing the coordinates of the vertices of the triangle.
After a rotation, the measures of the sides and angles of a triangle would also be the same. Similar to translation, the proportion of the triangle is unchanged after a rotation.
After a reflection, the triangle's sides and angles would still be the same since reflection is a rigid transformation and the proportion of the sides and angles are not changed.
Step-by-step explanation:
Rigid transformations, i.e. translations, rotations, and reflections, preserve the side lengths and angles of any figure. Therefore, after undergoing a series of rigid transformations, the side lengths and angle measures of any triangle will be the same as the original triangle, generally speaking, in another position.
