Answer:
41 feet
Step-by-step explanation:
We apply the theorem below:
If two similar triangles have a scale factor of a : b, then the ratio of their perimeters is a : b.
Let x be the perimeter of the smaller triangle
If the ratio of their heights is 6:5 and the perimeter of the larger triangle is 49.2 feet,
6:5=49.2:x
6/5=49.2/x
Cross multiplying
6x=49.2 X 5
6x=246
x=246/6=41
The perimeter of the smaller triangle is 41 feet
Answer:
1.22
53.08
Step-by-step explanation:
4. We can find the quarter circle, we can find the whole triangle, lets do that
The circle is, 1/4*(1)^2*pi, which is 1/4pi
The triangle is, 2 * 2 divided by 2, which is 2
2 - 1/4pi gives us the shaded part or
2 - 1/4*3.14
2 - 0.785 = 1.215 rounded to 1.22
5. The area of a cylinder is pir^2h. r is 10, h is 1.2
12pi cm^3
we have 20 m^3 which is 2000 cm^3
Let's divide,
2000/37.68 = 53.078, rounded gives us 53.08
Answer:
F(x) = 5x - 7
Step-by-step explanation:
25x - 5y = 35
-5y = - 25x +35
Y = 5x - 7
F(x) =5x - 7
you can simply answer Gl =2 r= g2/g1 6÷2 =3
glr^11 = 2× 3^11
