Nooooo but why ? Is it important
Step-by-step explanation:
65 + (y + 9) = 180 ---------- Sum of angles on a
straight line
y + 65 + 9 = 180
y + 74 = 180
y = 180 - 74 = 106
6x + 7 = y + 9 ----------- Alternate angles
But y = 106,
6x + 7 = 106 + 9
6x = 115 - 7
x = 108/6 = 18
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
Use pythagorean theorum: c^2 = a^2 + b^2, where BC = c, AB = a, AC = b
so b^2 = c^2 - a^2 --> b = SR(c^2 - a^2), where SR means square root of ( )
b = SR(64 - 49) = SR(15) = 3.873 = B) 3.87 units
Answer: 5
Step-by-step explanation:
A = xˆ(2−1)+yˆ(−1−(−1))+zˆ(0−(−3)) = xˆ +zˆ3,
|A| =
√
1+9 = 3.16,
aˆ =
A
|A|
=
xˆ +zˆ3
3.16
= xˆ 0.32+zˆ 0.95.
