Answer:
Step-by-step explanation:
reg. cones get 2 scoops, lg cones get 3 scoops
he scooped 234 regular cones.....234* 2 = 468 scoops
he scooped 156 lg cones.....156 * 3 = 468 scoops
thats a total of 468 + 468 = 936 scoops
each scoop weighs 3 oz.....so the total weight of the ice cream is :
936 * 3 = 2808 oz
1 lb is 16 oz....so 2808 oz is : 2808/16 = 175.5 lbs
if a tub of ice cream weighs 10 lbs, then richard used :
175.5 / 10 = 17.55.......he used 17.55 tubs full
Answer:
Step-by-step explanation:
<u>Use the law of cosines to find the side AB:</u>
<u>Use the Heron's area formula next:</u>
, where s- semi perimeter
- s = 1/2[x + x + 3 +
) = 1/2 (2x + 3 +
) - s - a = 1/2 (2x + 3 +
- 2x - 6) = 1/2 (
- 3) - s - b = 1/2 (2x + 3 +
- 2x) = 1/2 (
+ 3) - s - c = 1/2 (2x + 3 +
- 2
) = 1/2 (2x + 3 -
)
<u>Now</u>
- (s - a)(s - b) = 1/4 [(x²+3x+9) - 9] = 1/4 (x² + 3x)
- s(s - c) = 1/4 [(2x + 3)² - (x² + 3x + 9)] = 1/4 (3x²+ 9x) = 3/4(x² + 3x)
<u>Next</u>
- A² = 3/16(x² + 3x)(x² + 3x)
- 300 = 3/16(x² + 3x)²
- 1600 = (x² + 3x)²
- x² + 3x = 40
<u>Substitute this into the first equation:</u>
