What is the slant height of a square pyramid that has a surface area of 319 square feet and a side length of 11 feet?
Dafna1 [17]

Step-by-step explanation:

Surface area of a square pyramid is the area of the square base plus the area of the four triangles made from the base and the slant height.

SA = s² + 4(sh/2)

which reduces to:

SA = s² + 2sh

You are told that s = 11 and SA = 319. You can now solve for h:

319 = 11² + 2(11)h

319 = 121 + 22h

198 = 22h

h = 9 ft (answer C)

I hope it's helpful!!

Elizabeth has two identical number cubes. both cubes have faces numbered 1 through 6. If Elizabeth rolls each cube once, What is
Lelechka [254]
The sample space for the two identical dice (outcomes):

(1,1)(1,2)(1,3)(1,4)(1,5)(1,6)

(2,1)(2,2)(2,3)(2,4)(2,5)(2,6)

(3,1)(3,2)(3,3)(3,4)(3,5)(3,6)

(4,1)(4,2)(4,3)(4,4)(4,5)(4,6)

(5,1)(5,2)(5,3)(5,4)(5,5)(5,6)

<span>(6,1)(6,2)(6,3)(6,4)(6,5)(6,6)</span>

<span>
</span>

<span>So if Elizabeth rolls each cube once, there is 36 (6 x 6) possible outcomes.</span>

<span>Let E = event of getting a sum of 10.</span>

<span>The number which is a sum 10 will be:</span>

E = [(4,6), (5,5),(6,4)]

P(E) = number of favorable outcomes divided by total number of possible outcomes

        = 3 / 36 or 0.083

URGENT!! GIVING BRAINLIEST, 30 POINTS
Yakvenalex [24]

Answer:

No her calculations do not make sense because the area of the smaller walls together is 234 and not 244 the total square feet of the windows and doors are also wrong. She should also subtract the doors and windows from the total so she doesn't over spend on paint. Her answer is correct just the way of finding it is wrong.

Step-by-step explanation:

Walls total sqft: (2(13ft)(9ft))+(2(16ft)(9ft))=234ft²+288ft²=522ft²

Doors+Windows total sqft: ((2(20ft)+(2(15ft))=60ft²+30ft²=90ft²

Total amount of paint needed: 522ft²-90ft²=432ft²

Amount of gallons needed remains the same

Hopefully this makes sense.
