Answer:
= 54.78 square units
Step-by-step explanation:
We can calculate the area of the triangle using the formula;
Area = 1/2abSinθ ; where a and b is the sides making the angle θ.
Therefore;
Area = 1/2 bc sin C
= 1/2 × 16 × 7 × Sin 78
= 8 × 7 × sin 78
<u>= 54.78 square units</u>
1) at highest point V = 0
<span>so 0 = Vo - gt </span>
<span>=> t = Vo / g = 26.8 / 9.81 = 2.73 s <<<<<<<<, </span>
<span>2) find its highest point : </span>
<span>V^2 = Vo^2 - 2gh </span>
<span>hence h = Vo^2 / 2g = 36.6 m from its starting point </span>
<span>so total height = 36.6 + 2.1 = 38.7 m </span>
<span>applying h = Vot + 1/2 g t^2 u get : </span>
<span>38.7 = 0 + 1/2 (9.81) t^2 </span>
<span>=> t = 2.8 s <<<<<<<<<</span>
To find the case cube of a box in cubic feet, first measure its length, width, and height in inches. Next, multiply all 3 figures together, then divide the result by 1728 to get your case cube measurement in cubic feet.
First, turn the mixed numbers into a improper fraction.
next, find the GCF (greatest common factor)
finally, subtract the numerator, and your done!
P.s. I'm in middle school too. and i get A+ in math
GOOD LUCK!

no because mathematically 30X10=300 not 900 its would have to be 30X30 to get the product of 900 so therefore no your statement is incorrect
