Answer:
The amount of cardboard Digit Tech needs to
package all 1500 new Smart Phones = 891000 square cm
Step-by-step explanation:
Points to remember:-
<u>Surface area of cuboid</u>
Surface area = 2(lb + bh + lh)
Where, l - Length of cuboid
b - Breadth of cuboid and
h - Height of cuboid
It is given dimensions of cardboard box
12 cm long, 9 cm wide, and 9 cm high.
<u>To find the surface area of box</u>
Here l = 12 cm, b = 9 cm and h = 9 cm
Surface area = 2(lb + bh + lh) = 2[(9*12) + (9*9) + (12 * 9)]
= 2(108 + 81 + 108) = 2 * 297 = 594 square cm
To find the cardboard required for 1500 box
Total cardboard = 1500 * 594 = 891000 square cm
11)x+y=-2. 12)y=2x+1
2x-y=5. 2y=x +17
————— —————
y=1/3x+3 3y=3x÷3+18÷3
y=1x+6
if you have a problem similar to these that I did for you you just add the x variables and the y variables (if the y variable has any ) and divide the y variable with the 1st and 2nd variable
and you get the y=mx+b equation if you need the x variable too you multiply the y variable answer with the number beside it
Answer:
x intercept: 4
y intercept: 6
Step-by-step explanation:
3x + 2y = 12
to find the x and y intercept, you replace the other value with zero.
for example, to find the x intercept, you replace the y value with 0.
3x + 2(0) = 12
3x + 0 = 12
3x = 12
so, your x intercept is 4
Do the same for your y intercept
3(0) + 2y = 12
0 + 2y = 12
2y = 12
y = 6
Answer: 653,809 - 256,034 = 397,775
Check 397,775 + 256,034 = 653,809
25 = 5*5
36 = 6*6
48 is not a square number
