Answer: D
Step-by-step explanation:
Formula: A = 2(wl+hl+hw)
A = 2(5*3 + 7*3 + 7*5)
A = 2(15 + 21 + 35)
A = 2(71) = 142 sq inches
Answer:
$38.31
Step-by-step explanation:
Given:
Pure silver that cost $33.48 per ounce used to form $24.35 alloy/ounce.
Question asked:
How many ounces of pure silver were used to make an alloy of silver costing $27.87 per ounce?
Solution:
At cost $24.35/ounce, pure silver is mixed = $33.48
At cost $1/ounce, pure silver is mixed =
At cost $27.87/ounce, pure silver is mixed =
Thus, $38.31 ounces of pure silver were used to make an alloy of silver costing $27.87 per ounce.
11.84 because if you add .68 to .16 you get 84
The graph of vector v with an initial point at R (–19, 6) and terminal point at S (–35, 13). Option C; v = -16i + 7j represents the linear form of RS.
<h3>How to find the vector component?</h3>
If we have given a vector v of initial point A and terminal point B
v = ai + bj
then the components form as;
AB = xi + yj
Here, xi and yj are the components of the vector.
c
Given;
The graph of vector v with an initial point at R (–19, 6) and terminal point at S (–35, 13).
v = (-35 +19)i + (13 - 6)j
v = (-16)i + (7)j
v = -16i + 7j
Thus, Option C; v = -16i + 7j represents the linear form of RS.
