Answer:
The rate at which the distance between the two cars is increasing is 30 mi/h
Step-by-step explanation:
Given;
speed of the first car, v₁ = 24 mi/h
speed of the second car, v₂ = 18 mi/h
Two hours later, the position of the cars is calculated as;
position of the first car, d₁ = 24 mi/h x 2 h = 48 mi
position of the second car, d₂ = 18 mi/h x 2 h = 36 mi
The displacement of the two car is calculated as;
displacement, d² = 48² + 36²
d² = 3600
d = √3600
d = 60 mi
The rate at which this displacement is changing = (60 mi) / (2h)
= 30 mi/h
Answer:
The probability of drawing a purple marble is 3/10
i converted them to decimal
-70% = -0.70
Explanation: Every time you need to change percentage to decimal, move the decimal 2 times to the left.
0.34 = 0.34
Explanation: It stays the same because it is already in decimal form.
-2/5 = -0.40
Explanation: you divide with a calculator -2 divided by 5 and that is- 0.40 or you can change the denominator to 100 which you multiply the numerator and denominator by 20: 5*20=100 and -2*20=40 then -40/100 is -0.40
0.96% = 0.0096
Explanation: Every time you need to change percentage to decimal, move the decimal 2 times to the left.
-0.70, 0.34, -0.40, 0.0096
least to greatest:
-0.70, -0.40, 0.0096. 0.34
Answer:
False
Step-by-step explanation:
To find the area of the square, you multiply length by length, adding the length of all 4 sides would be the perimeter
To start I would add 400 + 200, and that equals 600.
Then I would add 30 + 50, and that equals 80.
And then I have 2 left over.
600 + 80 = 680
Add the left over 2, so 680 + 2
680 + 2 = 682. Your answer is 682.
I hope this helps!
