160
Step-by-step explanation:
you need to multiply the ounces of gas by 4 like you did to the oil.
Answer: Arjun paid more than Anu of about $2000.
Total cost
unit amount × per unit cost
For Anu total cost:
⇒ 15 × $225
⇒ $3375
For Arjun total cost:
⇒ 25 × $215
⇒ $5375
Anu paid $3375 for each whereas Arjun paid $5375 for each.
Conclusion: Arjun paid more.
Answer:
a ≤ 20/3
Step-by-step explanation:
Subtract 4 from both sides, obtaining:
-3a ≥ -20. Dividing both sides by -3, we get a ≤ 20/3.
Note that because this is an inequality, and because we've divided all terms by a negative number, we must change the direction of the inequality symbol from ≥ to ≤.
Answer:
-8
Step-by-step explanation:
Turn the equation into slope intercept form [ y = mx + b ]
y + 11 = 2(x + 1.5)
~Distribute right side
y + 11 = 2x + 3
~Subtract 11 to both sides
y = 2x - 8
"b" represents the y-intercept, so, the y-intercept is -8.
Best of Luck!
Answer:
x=8.2
Step-by-step explanation:
First, figure out which trig function you are going to use.
In this problem you are dealing with the opposite side to the angle and the hypotenuse, and if you remember SOH CAH TOA, this requires sine.
sin (55) =opposite/hypotenuse
sin (55) =x/10
multiply both sides by 10 to get 10 * sin (55) = x
10 * sin (55) = 8.2
