Answer:
7 cm
Step-by-step explanation:
We are told that the pyramid has a square base of an area of 49 cm².
Therefore, the side length of the base of the pyramid is still the same as the side length of a square having an area of 49 cm².
Area of a square = s², where s is the side length of the square.
The side length of the base can be gotten using the following equation,
Solve for s by looking for the share root of both sides.
The side length of the base = 7 cm
Answer:
500
Step-by-step explanation:
So first off we know that there are 9000 (9k) natural 4-digit numbers -->
we solve using permutations so we can set the problem up like this
1 2 3 4
4 x 5 x 5 x 5 = 100 x 5 = 500
Reasoning:
So the reason we can do it like this is because -->
even numbers are: 0, 2, 4, 6, 8
ALL DIGITS MUST BE EVEN --> calculate using permutations simply makes it 5^4 but that's NOT our answer. Since the first digit can't be zero, we have -->
4, 5, 5, 5 respectively
Multiply this (by rule of permutations) to get, => 20 x 5 = 100
100 x 5 = 500
Thus, we have our answer of 500

Just look at the perpendicular cross section, which would be an isosceles triangle. Split that in half vertically and you get a right triangle.
Answer:
40% * 71 = Markup price
40% of 71 is 28.4, so i added the two together and got 99.4
so...
$28.4 + $71 = $99.40
Answer:
C
Step-by-step explanation:
f(x) × g(x)
= × (x³ - 12)
= × (x³ - 12)
= (x + 6)(x³ - 12) ← distribute the parenthesis
= - 12x + 6x³ - 72
= + 6x³ - 12x - 72
