First, you have to find the LCD. The LCD of 4 and 7 is 28, so you rewrite the fraction:
7/28
4/28
Then you add them.
Answer:
17/20 cm
Step-by-step explanation:
At first it would be 85/100. Then you would divide both the numerator and denominator by 5 to get 17/20
a. The general equation for a circle centered at 
with radius 
is
The described circle has equation
We know the circle passes through the origin. This means that the equation above holds for 
and 
. The distance between any point on the circle and its center is the radius, so we can use this fact to determine :
So the circle's equation is
b. If the distance between point B and the center is less than 
, then B lies inside the circle. If the distance is greater than , it falls outside the circle. Otherwise, if the distance is exactly , then B lies on the circle.
The distance from B to the center is
, so 
, which means B falls outside the circle.
B x h = triangle area
triangle area= 160
height= 10
b x 10 (divide it by) 2= b
160 x 2 (divide it by) 10= b
32= b
the height of the this triangle is 32
Answer:
Yes
Step-by-step explanation:
Example: Let class one have 5 male students and 4 female students and let class two have 10 male students and 8 female students, then the single class will have 15 male student and 12 female students which are in a ratio of 5:4
