Answer: A company saves $134.38 by choosing to make 50 of Box 2 instead of Box 1
Step-by-step explanation:
Hi, to answer this question we have to calculate the surface area of both boxes.
<em>Surface area (A) = 2wl + 2lh + 2hw,
</em>
Where w is width, l is length , and h is height.
- Box 1 = A = 2(6x20) + 2( 20x4) + 2 (4 x 6) =2 (120)+ 2 (80)+ 2(24) =448 in2
- Box 2 = A = 2 (4x15)+ 2(15x8)+ 2(8x4) = 2(60)+2(120)+2(32)=424 in2
Since 1 inch = 0.0833333 foot
- Box 1 = 448 in2 x 0,0833333 =37.34 ft2
- Box 2= 424 in2 x 0,0833333 =35.19 ft2
Since the material used to make a storage box costs $1.25 per square foot.
- Box 1 =37.34 ft2 x1.25 = $ 46.675
- Box 2= 35.19 ft2 x 1.25 =$43.98
Since 50 of each are made:
- Box 1 = $ 46.675 x50 =2,333.750
- Box 2= $43.98 x50 =2,199.37
Subtracting both costs:
2,333.750(1) - 2,199.37(2) = $134.38
(3x - 2)^2 is the same as:
(3x - 2)(3x - 2)
use the FOIL method: First, Outside, Inside, Last
3x(3x) = 9x²
3x(-2) = -6x
-2(3x) = -6x
-2(-2) = 4
9x² - 6x - 6x + 4
Combine like terms
9x² (- 6x - 6x) + 4
9x² - 12x + 4 is your answer
hope this helps
Answer:
the four consecutive odd integers are: 51, 53, 55, 57
Step-by-step explanation:
(7 + 5i) + (8 - 3i) Expand the brackets.
7 + 5i + 8 - 3i Add the terms with i together
7 + 8 + 5i - 3i Add or subtract as the case
15 + 2i
1. so you have $114
weekdays weekends
18. 21
just divide 114 by 18 and 21
114÷18 = 6.3 which means 6 tickets
and 114÷ 21 = 5.4 which gives us 5 tickets
so the answer is
for weekdays the max ticket number I can get is 6 and for weekends is 5
2. we do the same method as above
for the lawn ( weekdays) seat we get 20 tickets
and for the lower box (weekend) we get 6 tickets max.
3. bleachers weekend seats = 20 tickets
line box weekday seats = 19 tickets
4. both of them can give exactly 7 tickets
