Step-by-step explanation:
Tuesday: 3 x 3 = 9
Wednesday: 9 x 3 = 27
Thursday: 27 x 3 = 81
Answer:
2,4,6 and 8 are all 40degrees that means 1,3,5 and 7 are 140 degrees. 2,4,6, and 8 are at a diagonal that allows them to equal eachother. because 2 is given 40degrees as the angle 4,6 and 8 must also be 40 degrees. a flat line is 180 degrees. 180-40=140
you have vertical angles alternate interior, alternate exterior
Step-by-step explanation:
Vertical Angles: a pair of opposite congruent non-adjacent angles formed by intersecting lines; share a vertex
Alternate Interior: when a transversal intersects two lines, alternate interior angles are on opposite sides of the transversal and on the inside of the given lines
Alternate Exterior: when a transversal intersects two lines, alternate exterior angles are on opposite sides of the transversal and on the outside of the given lines They are congruent.
Answer:
1) B, 48
2) C. 180=2x2x3x15

<em>Compatible numbers</em> are numbers that are easy to use in mental arithmetic.
Martin gave away ⅖ of 7 lb of grapes, so the amount he gave away was
⅖ × 7 lb
⅖ is close to ²/₄ (½), and it is easy to take half of something mentally.
Half of 7 is about 3, so Martin gave away about 3 lb of grapes (the exact answer is 2.8 lb).
