Answer:
$7.38
Step-by-step explanation:
multiply 49.20 by 15 percent.
Given function:
y=-7.3x+39.7
Where y= number of gallons of water
and x= number of minutes
Put value of y=17.8 gallons and solving for x.
17.8=-7.3x+39.7
Subtract 39.7 from both sides
-21.9=-7.3x
Divide both sides by -7.3
3=x
or
x=3 minutes
After 3 minutes the water in the tub will be 17.8 gallons.
Answer: 3 minutes
Answer:
65
Step-by-step explanation:
(4-7i)(4+7i) =16 + 28i-28i -49i^2 ➡16 - 49i^2
16 + 49 = 65
the fault here is i^2= -1 and -1 multiplied by -49 is +49 not -49
Answer: 2.5 cups of flour is needed for 5 eggs.
Step-by-step explanation:
The crepe recipe calls for 2 eggs, 1 cup of flour, and 1 cup of milk. This means that the ratio of eggs to cup of flour to cup of milk required is 2:1:1
Therefore, if you use 5 eggs, the proportions would increase by 2.5. Multiplying by 2.5, it becomes
5 : 2.5 : 2.5
Therefore, you would need 2.5 cups of flour for 5 eggs.
The solution would be ... m = <span>√2 - 48 over 16. Have a good day :)</span>
