A culture started with 5000 bacteria. after 7 hours, it grew to 6500 bacteria. predict how many bacteria will be present after 1

spin [16.1K]

6500=7x+5000

6500-5000=7x+5000-5000

1500=7x

1500/7≈214

x≈214

y=19·214+5000

y=9066

answer=9066 bacteria

What is the answer to the question?

Anuta_ua [19.1K]

Answer:

Given : PQ = RQ

to find : angle B

PQ = RQ
Angle B = angle QRP ( angle opposite to equal side are equal). ...(1)
angle QRP + 140° = 180° ( linear pair)
angle QRP = 180° - 140°
angle QRP = 40°
from equation (1)
Angle B = angle QRP = 40°
