25. You need to divide 3240 by 6, and 1100 by 2. Are those equal? That's what it's asking. It would not be equal, because 3,240 miles would be 540 miles per hour and 1100 would be 550 per hour. Very close, however.
26. If 15 scoops makes 5 gallons, then divide 15/5. That's 3 scoops per gallon. It's asking how many gallons can be made with 6 scoops. That would be 2 gallons.
27. All it's asking is 38 times 5, which would be 190.
28. Since 5 gallons goes into 15 gallons three times, you would divide $22.20 by 3. That would be $7.40 each 5 gallons.
Answer:
5/36
Step-by-step explanation:
Look at picture in link for explanation
Let the side of the square base be x, and the height of the box be h.
<span>The material of the base is x^2, and the material of the four sides is 4xh. </span>
<span>4000 = hx^2 </span>
<span>h = 4000/x^2 </span>
<span>The total material is </span>
<span>M = x^2 + 4x(4000/x^2) = x^2 + 16000/x </span>
<span>Take the first derivative of M and set equal to 0. </span>
<span>M' = 2x - 16000/x^2 = 0 </span>
<span>Multiply by x^2: </span>
<span>2x^3 = 16000 </span>
<span>x^3 = 8000 </span>
<span>x = 20; h = 10; M = 1200</span>
-12 is an integer number, and you can write it as {-12}{1}
7.3 is a rational number, and you can write is as {73}{10}
0.41 is a rational number, and you can write is as {41}{100}
6 is a whole number, and you can write it as {6}{1}
3 1/2 is a rational number, and you can write is as
3+{1}{2}={6}{2}+{1}{2}={7}{2}
Hopes this helps also will you mind giving me brainliest?
