12,250 - 250= 12,000
12,000 divided by 4 = 3,000
Serge has to save 3,000 a year
so 3,000 divided by 12 = 250.
Serge has to save 250 a month
Let's say you have 20 friends over. 6 more are coming over. And they all want 3 slices of pizza.
So to figure out how many slices of pizza you would need, you'd use this equation: 3•(20+6)
A) h = 2sqrt2 because for a 45-45-90 triangle both legs have the same measurement and to find the hypotenuse, you would multiply the leg by square root of 2.
b) d = sqrt3 because in order to find the short leg for a 30-60-90 triangle, you would need to divide your long leg by a square root of 3 (if you have the hypotenuse and wanted to find the short leg, divide the hypotenuse by 2).
Answer:
1,6,2 and 5
Step-by-step explanation:
(2x/5)² . (1x⁴/4)^-1
=(2²x²/5²) . (4/x⁴)
=4x²/25 × 4/x⁴
= 16/25x²
