Represent the unknowns.
<span>Let x = length </span>
<span>since the width is 3/4 of the length, </span>
<span>Let (3/4)x = width </span>
<span>Recall that the area of rectangle is just width multiplied by the length, </span>
<span>A = w * l </span>
<span>Substituting, </span>
<span>432 = (3/4)x * x </span>
<span>432 = (3/4)x^2 </span>
<span>432 * 4/3 = x^2 </span>
<span>576 = x^2 </span>
<span>Get the square root of both sides, </span>
<span>x = 24 feet (length) </span>
Answer:
306 inches
Step-by-step explanation:
80% = 0.8
170 inches × 80% = 170 × 0.8 = 136
The truck is 80% longer than the boat. 80% of the boat is 136.
So, the boat is 170 inches + 136 inches = 306 inches.
Answer:
4,944 kg of strawberries
Step-by-step explanation:
In order to know the amount of strawberries Berry Delicious used this year, you have to know how much is 60% of 3,090 kg of strawberries. You can solve this by multiplying 3,090 by 60%.
Let's solve.
- 3,090 kg x 60% (0.60) = 1,854 kg
Next, we have to add 1,854 kg to 3,090 kg.
- 3,090 kg + 1,854 kg = 4,944 kg of strawberries
<u>Therefore, Berry Delicious used 4,944 kg of strawberries this year.</u> <em>This is 1,854 kg more than last year's.</em>
