Answer:
The value of a that can substituted into equation D = 4b + 5
Step-by-step explanation:
Given that:
a = 4b + 5 ---- (equation c)
a = 6b - 2 ---- (equation d)
Replace the value of a = 4b + 5 into "a" in (equation d) to solve the system of equations.
So;
4b + 5 = 6b -2
5 + 2 = 6b -4b
7 = 2b
b = 7/2
b = 3.5
8000*2.5/100=200$

Step-by-step explanation:
Given that,
Radius of cone, r = 7 inches
Slant height of the cone, l = 11 inches
We need to find the height of the cone. Let the height be h. Using trigonometry to find it as follows :
So, the height of the cone is equal to .
Answer:
$0.50/cm
Step-by-step explanation:
Answer:
n = 24
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= =
hence
= ( cross- multiply )
35n = 30 × 28 = 840 ( divide both sides by 35 )
n = = 24
