Elizabeth drove 2 fifths of a mile in 30 seconds. What is Elizabeth’s speed

Mathematics
1 answer:
lora16 [44]3 years ago
4 0

Answer:

0.8 miles in a minute, which would be <u>40 miles a hour.</u>

Step-by-step explanation:

2/5 = 0.4

0.4 times 2 = 0.8

30 seconds times 2 = 60 seconds or 1 minute

60 times 0.8 = 40

60 times 1 minute = 60 minutes or 1 hour

40 miles in an hour or known as <u>40 miles a hour.</u>

3. At the start of summer, Ben has $250 . He takes a summer
earnstyle [38]

Answer:

Week 4

Step-by-step explanation:

Ben has $250 in the beginning.  He saves $150 per week.

y = 150x + 250

Tim has $1,650 in the beginning.  He spends $200 per week.

y = 1650 - 200x

We are trying to find which x-value produces the same y-value for both equations.  You can do this by setting both equations equal to each other.

150x + 250 = 1650 - 200x

(150x + 250) + 200x = (1650 - 200x) + 200x

350x + 250 = 1650

(350x + 250) - 250 = (1650) - 250

350x = 1400

(350x)/350 = (1400)/350

x = 4

By week 4, they will have the same amount of money.

How do I know when a dog is pregnant
chubhunter [2.5K]
PHYSICAL changes.
In the final third (weeks 6-9) of pregnancy, the dog’s belly becomes rounded and distended. Her mammary glands start to develop and become more obviously swollen, as they get ready to produce milk.
Behavioral changes.
APPETITE changes.
Towards the end of pregnancy, the dog’s will womb grow larger and take up more space in her belly. She won't be able to accommodate large meals, so she'll start wanting to snack, eating a little at a time more frequently.
NESTING
Watch for nesting. When it is nearly time for her to deliver the pups, the dog may start to nest. [3] She will gather blankets or clothing in a secluded place as she prepares a suitable safe warm environment for her imminent new arrivals.
The exact timing of nesting varies from 2-3 weeks to 2 - 3 days prior to giving birth.
