Let, the cost of a belt = x
cost of a wallet = y
Then, system of equations would be:
x + y = 42
7x + 4y = 213
Multiply 1st equation by 4,
4x + 4y = 168
Substitute it from 2nd equation,
3x = 45
x = 15
Now, substitute it in 1st equation,
15 + y = 42
y = 42 - 15 = 27
In short, Belt costs $15 and wallet costs $27
Hope this helps!
To answer this item, we assume that the topic is in similar polygons such that the ratio of the corresponding sides should be equal. In this item,
BY/YC = AX/XC
Substituting the known values,
6/10 = 18/XC
The value of XC from the equation is 30. The answer is letter C.
We are given 2 sides 18.7, 16.1 and a NON-included angle.
We have to calculate the altitude of the triangle.
altitude = 18.7 * sine (35)
altitude = 18.7 * 0.57358
altitude =
<span>
<span>
<span>
10.725946
</span>
</span>
</span>
In this case, side c is greater than the altitude and is less than side a so 2 two triangles will be formed.

Answer:
23 feet
Step-by-step explanation:
Givens
Volume = pi r^2 h
r = 11
V = 2783 pi
Solution
2783 pi = pi 11^2 * h Cancel the 2 pi's
2783 = 11^2 h Expand 11^2
2783 = 121 * h Divide by 121
2783/121 = h
h = 23 feet
