Answer:
A=60
B=36
A, is greater
Step-by-step explanation:
The answer is A. A cylinder with radius of 2.
When the rectangle rotates with respect to line 'm' the side having the longer measure which is side with 2 units will be overlapping the side of 1 unit.
Answer:
(26/9 , -7/9)
Step-by-step explanation:
Here,
let the points be
X(-1,7) = (x1, y1)
Y(4,-3) = (x2,y2)
and let the ratio be...
m:n = 7:2
and.. let the point that divides the line be
P(x,y)
now using the section formula for internal division..
P(x,y) = ( m.x2 + nx.1 / m+ n , my2+ny2/m+n )
= ( 7.4+2.-1 / 7+2 , 7.-3 + 2.7/7+2 )
= ( 26/9 , -7/9 )
Answer:
Correct answer: A₁ : A = 1 : 9
Step-by-step explanation:
Given: a = 3 a₁
Side of the first triangle let be a and of the second a₁
Area of the first triangle let be A and of the second A₁
If the two triangles are similar then it is:
A₁ : A = a₁² : a²
A₁ : A = a₁² : (3 a₁)² = a₁² : 9 a₁² = 1 : 9
A₁ : A = 1 : 9
God is with you!!!
Perimeter is the sum of all three sides so in this case x+(3x+2)+(3x+2).
They also gave us the perimeter which is 39 so
39= x+(3x+2)+(3x+2)
Simplify so 39=7x+4. [x+3x+3x=7x and 2+2=4]
Then get x by itself so subtract 4 from both sides.
35=7x
Then divide both sides by 7 to get x by itself.
Which leaves us with
X=5
