Answer:
2012.87
Step-by-step explanation:
Increased amount = 17% of 2024 = 0.17 * 2024 = 344.08
Amount after increment = 2024 + 344.08 = 2368.08
Decreased amount = 15% of 2368.08
= 0.15 * 2368.08
= 355.212 = 355.21
Final amount = 2368.08 - 355.21 = 2012.87
Answer:
9 + 7x
Step-by-step explanation:
14 + 3х - 5 + 4х
Subtract the numbers, and add the x's together.
9 + 7x
This is the furthest the expression can be simplified.
Hope this helps :)
Answer:
10.4 cm
Step-by-step explanation:
The volume (V) of a pyramid is calculated using
V = area of base × height (h)
area of square base = 6² = 36, thus
× 36h = 120
12h = 120 ( divide both sides by 12 )
h = 10 cm
To find the slant height (s) consider the right triangle from the vertex to the midpoint of the base and from the midpoint of base to the side.
That is a right triangle with hypotenuse s and legs 10(h) and 3 (midpoint of the base )
Using Pythagoras' identity then
s² = 10² + 3² = 100 + 9 = 109
Take the square root of both sides
s = ≈ 10.4 cm
