Answer:
45.2 × 10⁰ = 45.2 (a⁰ = 1 )
45.2 × 10¹ = 452
45.2 × 10² = 4520
45.2 × 10³ = 45200
Answer: the first, second, and fourth are correct.
Step-by-step explanation:
28-10%=25.2
28-25%=21
28-35%=18.2
Answer: should be 70+50x is less than 320
Step-by-step explanation:$70 is only added once, and for 5 hours, she pays him a certain amount of $(x). I don't know if the multiple choices are valid
4<x<20 should be the correct answer. Good luck.
Answer:
C) △JKL is not congruent to △J′K′L′ because there is no sequence of rigid motions that maps △JKL to △J′K′L′.
Step-by-step explanation:
If L' were (-3,-4), it would be a reflection of L across the x-axis as J' and K' are with respect to J and K. Unfortunately, because it is not, the side lengths J'L' and K'L' of triangle J'K'L' are different from those of triangle JKL. This ensures the triangles JKL and J'K'L' are <em>not congruent</em>.
