Answer:
step 3 is incorrect and x = 10/ 8
Answer:
0.42
Step-by-step explanation:
→ Use Pythagoras to find YZ
√2.5² - 0.7² = 2.4
→ Half the answer to find YW
2.4 ÷ 2 = 1.2
→ Substitute the values into the formula for the area of a triangle
0.5 × 0.7 × 1.2 = 0.42
Answer:
558.036 lb
Step-by-step explanation:
Let x is the amount of the sea water to collect 125 lb of sea salt
As given: 64 lb/ft³ has 0.0035 dissolved salt by weight
So the formula to find out the amount of the sea water is:
64 lb/ft³ * 0.0035 *x ft³ = 125 lb
<=> x = = 558.036 lb
Hope it will find you well.
Answer: y = -4/3x + 15
3y = 45 - 4x (subtract 4x from both sides)
y = -4/3x + 15 (divide both sides by 3)
Answer: -58
Explanation: Evaluate the exponent
−64 x 3/4 -10
Then you Multiply the numbers
—64x3/4 -10
-48-10
Subtract the numbers
-58
And -58 is the solution
