Step-by-step explanation:
99- (-17)= 99+17
Answer:
-
Step-by-step explanation:
using the half angle formula
cos( ) = ±
cos195° = cos(180 + 15)° = - cos15°
then
cos15° = cos ( ) = = = =
then
cos195° = - cos15° = -
The answer is 13/85. You could find out the answer by doing the reprical multiplication.
Given:
The height of the given trapezoid = 6 in
The area of the trapezoid = 72 in²
Also given, one base of the trapezoid is 6 inches longer than the other base
To find the lengths of the bases.
Formula
The area of the trapezoid is
where, h be the height of the trapezoid
be the shorter base
be the longer base
As per the given problem,
Now,
Putting, A=72, and h=6 we get,
or,
or,
or,
or,
or,
So,
The shorter base is 9 in and the other base is = (6+9) = 15 in
Hence,
One base is 9 inches for one of the bases and 15 inches for the other base.
Answer:
Arianna should receive $3.05 in change.
Step-by-step explanation:
In order to find the answer, you have to find the cost of the three balls by multiplying the cost per ball for the number of balls and then, you have to subtract this amount from five to find the change Arianna should receive:
$0.65*3=$1.95
$5-$1.95=$3.05
According to this, the answer is that Arianna should receive $3.05 in change.
