Since the question wants to know how many ingredients she used, All we have to do is add them.
So as the question says, she used 6/10 flour, 3 eggs, and 4/5 sugar.
Now we have two fractions in this scenario. Let's make them have the same denominator. Either we divide 6/10 by 2 or multiply 4/5 by 2. Let's multiply.
4/5 × 2 = 8/10
Now we have 6/10, 3, and 8/10
Lets add them together.
3 + 6/10 = 3 and 6/10
Now 3 and 6/10 + 8/10 = 4 and 4/10
Simplify even further...
and your answer will be 4 and 2/5
To find the unit rate, we need to divide 6 by 51.
51/6 = 8.50

Answer:
y = - 16t² + 55.6t + 6
Step-by-step explanation:
Using y - y₀ = vt - 1/2gt² where g = 32 ft/s², and v the velocity of the football
So y = y₀ + vt - 1/2 × (32 ft/s²)t²
y = y₀ + vt - 16t² where y₀ = 6.5 ft
y = 6 + vt - 16t²
Now, when t = 3.5 s, that is the time the teammate catches the ball after the quarterback throws it, y = 5 ft. Substituting these into the equation, we have
5 = 6.5 + v(3.5 s) - 16(3.5 s)²
5 = 6.5 + 3.5v - 196
collecting like terms, we have
5 - 6.5 + 196 = 3.5v
194.5 = 3.5v
v = 194.5/3.5 = 55.57 ft/s ≅ 55.6 ft/s
So, substituting v into y, our quadratic model is
y = 6 + 55.6t - 16t²
re-arranging, we have
y = - 16t² + 55.6t + 6
A greater fraction than 4/5 is 9/10
