Answer:
128 + 96√3 or 294.28 unit^3 to the nearest hundredth.
Step-by-step explanation:
The surface area of one of the pyramids = area of the square base + area of the 4 equilateral triangles
= 8^2 + 4 * 1/2 * 8 * 4√3
= 64 + 64√3.
So the area of the new solid = 2(64 + 64√3) - area of 2 triangles
= 2(64 + 64√3) - 32√3
= 128 + 128√3 - 32√3
= 128 + 96√3.
I don’t know I am just guessing but it’s False good luck
1st answer : 1116 - (6x19) /6
If the family buys 6 tickets and the travel insurance is $19 per ticket:
6 x $19 = $114
Take away the total cost from the insurance
$1,116 - $114 =$1,002
6 tickets cost $1,002
Divide $1,002 by 6
$1,002 / 6 = $167
2nd ANSWER::: each ticket costs $167
Answer:
Step-by-step explanation:
3n + 5d = 20.25
24n + 40d = 162
8n + 8d = 38
-24n - 24d = -114
24n + 40d = 162
-24n - 24d = -114
—————————
16d = 48
d = 3
A drive costs $3
3n + 5(3) = 20.25
n = 1.76
A notebook costs $1.75
