Answer:
96 ft²
Step-by-step explanation:
The general formula for the surface area of a pyramid is:
SA =
pl + B, were p = the perimeter of the base, l = the slant height and B = the area of the base
Since the area of the base is 36 ft², then each side is √36, or 6 ft. The perimeter is the sum of all the sides, so 6 x 4 = 24 ft.
Given the overall height of the pyramid is 4 feet, you can use the Pythagorean Theorem (a² + b² = c²) to find the slant height (hypotenuse) of the pyramid. Using 3 feet for 'a' and 4 feet for 'b':
3² + 4² = c² or 9 + 16 = 25
25 = c² or c = 5
SA =
(24)(5) + 36
SA = 60 + 36 = 96 ft²
Answer:
try right 3, up 4. if not, try right 4, up 3.
If each pack of trail mixes is targeted to weigh 9.25 oz and must be within 0.23 oz of the target in order to be accepted, then rejected masses x, are those which weighs less than 9.02 oz or greater than 9.48 oz.
(1) Snow fall in last week =
inches
Snow fall in today=
inches
Let us first change mixed fraction to improper fraction.

Now, make the denominators same.
, 
Now, find the difference between 14/4 and 23/4.
So, compared to last week
more inches of snow fell today.
(2) Given three times a number, minus nine, equals six times six, divided by four.
Let a number be X.
3X – 9 = 6 × 6/4
(3) To solve the equation:
3X – 9 = 6 × 6/4
3X – 9 = 36/4
3X – 9 = 9
3X = 18
X = 6
Answer:
5r + 2p + 6
Step-by-step explanation:
= 4r + 9 + r + 2p - 3
= 4r + r + 2p + 9 - 3
= 5r + 2p + 6
