Answer:
AB = 4.41
Step-by-step explanation:
→You are given the adjacent side and need to find the hypotenuse. For this, we use cos.
<u>→Set it up, like so:</u>
<u />
<u>→To get rid of the x in the denominator, multiply everything by x:</u>
<u />
<u>→Divide both sides by cos25:</u>
x = 4.413
<u>→Round to nearest hundredth:</u>
x = 4.41

Answer:
Let x represents the ounces of first spice.
From the given statements, you draw a table as shown below:
ounces of spice Percentage ounces of salt
First spice x 3% 0.03x
Second spice 175 6% 175(0.06)
Final mixture x+ 175 5% (x+175)(0.05)
Now, to solve for x;
Final spice = First spice + second spice
Subtract 10.5 on both sides we have;
Simplify:
Subtract 0.05x on both sides;
Simplify:
Divide both sides by -0.02, we get;
x = 87.5 ounces
Therefore, 87.5 ounces of spices i.e 3% salt should be added to 175 ounces of a spice that is 6% salt in order to make a spice that is 5% salt
