Answer:
80 in.²
Step-by-step explanation:
The total surface area of the pyramid is the sum of the area of the base and the areas of the 4 triangular sides.
Square: area = s²
Square: side = 4 in.
Triangular side: area = bh/2
Triangular side: base = 4 in.; height = 8 in.
Area of the base: s² = (4 in.)² = 16 in.²
Total area of the 4 triangular sides: 4 × bh/2 = 2bh = 2 × 4 in. × 8 in. = 64 in.²
Surface area = 16 in.² + 64 in.² = 80 in.²
Answer:
-5<x<10
Step-by-step explanation:
1) -6< x-1<9
you take -1 out for both sides and it changes the sign
-6 +1< x< 9+1
-5<x<10
Good luck!
Answer:
She can invite 109 guests and be right on top of budget. If she wants to spend less than her budget though she can only invite 108 people.
Step-by-step explanation:
First you have to subtract 5,748 - 2,478 which is 3270. Next you have to divide 3270 by 30 because each person costs 30 dollars. 3270 divided by 30 is 109.
I hope this helps! Please mark me brainliest if I am correct! Have a nice day!

<span>What is the height of the plane to the nearest meter?
Answer: 559 m.
Explanation:
1) The horizontal distance between the plane and tha atoll makes a right triangle with the height, with the depression angle between the two legs.
2) Therefore, you can use the tangent trigonometric ratio:
tan(10°) = opposite-leg / adyacent-leg = height / horizontal distance
⇒ height = horizontal distance × tan (10°)
⇒ height = 3,172 m × tan(10°) = 559.31 m, which rounded to the nearest m is 559
