Answer:
Step-by-step explanation:
The volume of the mentioned object is
Where is the base area, which is defined , because the base is a square which side is units long.
Additionally, we know that the volume of the object is
Replacing the first expression and the volume of the base, we have
Therefore, the expression that represents the height of the volume is
Draw the triangle as shown in the figure below.
a=5.3, b=7, c=4.
The smallest angle is ∠C because it is opposite the shortest length of 4.
From the Law of Cosines,
c² = a² + b² - 2ab cosC
or
cos C = (a² + b² - c²)/(2ab)
= (5.3² + 7² - 4²)/(2*5.3*7)
= 0.823
∠C = arcos(0.823) = 34.58°
This answer agrees reasonably with 34.38°
Answer:
157.8
Step-by-step explanation:
so since its on a 80% discount we want to see how much 80% is on $790 which was its initial price. To find out the percentage of $790 we need to multiply $790 by 0.80 which will equal to 631.2.
the answer is 157.8
you have to subtract 790 with 631.2
S=27
Use the equation given and substitute 53.45 for c and 63 for r, like indicated in the problem. Then solve and get s=27.
It’s the 3rd option. It would be that bc you are checking by rounding your number up.
