Answer:
12.21ft³
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, square based pyramid.
Volume of square based pyramid is expressed as
V= a²(h/3)
Given data
Perimeter p = 7.3ft
Height h= 11.1ft
Since the shape has a square base let us solve for the length of each side
Perimeter of square p = a+a+a+a
p= 4a
7.3= 4a
a= 7.3/4
a= 1.83ft
Substituting our given data we have
Volume = 1.83²(11.1/3)
V= 3.3*3.7
V= 12.21ft³
Answer:
$4.29
Step-by-step explanation:
An easy way to do this is to move the decimal point to the left one space.
So 42.87 would become 4.287
But since we are talking about currency, we only want two numbers to the right of the decimal point: 4.28.
And since we are rounding to the nearest cent, the 7 on the end means we round up by 1, making the final answer 4.29!
<span>An angle measuring (870n)° is in standard position.The value of n in which the terminal side falls along the positive portion of the y-axis would be 1. This is because the reference angle would fall on the second quadrant, which still denotes a positive portion of the y-axis.</span>
Answer:
,n n,
Step-by-step explanation:
First it is reflected in the x axis (beacuse the x value becomes negative but the y values stays the same)
second its dilated by a factor of a half ( the sides of the figure are reduced by a half)
then its translated 2 units to the left and 2 units upwards
