Answer:
The number of hours that she work for the fast food is 11
The number of hours that she mowed is 5
Step-by-step explanation:
let x= hours spent mowing
y= hours spent at the food joint.
we can now form an equations from the figures given.
x+y=16...*
10.5x+4.25y=136.75...**
solving the two equations simultaneously using the substitution method or the eliminating method,
x=11 hours
y=5 hours
Answer:
When factoring by grouping also called factoring in pairs, we should split the expression into two pairs that have something in common. The idea is that after we factor each pair, we get a binomial common factor.
Step-by-step explanation:
The area of the circle would be 50.27 i think
To answer, first, convert the given velocity in km/h to m/s as shown below,
(144 km / hr) x (1000 m / 1 km) x (1 hr / 3600 s) = 40 m/s
The acceleration (a) is solved by through the equation,
a = (Vf - Vi) / Δt
where Vf and Vi are final and initial velocities, respectively and Δt is change in time. Substituting the known values,
a = (0 - 40 m/s) / 12 s = -3.3 m/s²
Thus, the answer to this item is letter B.
The answer is the third one. (Rx + Py = -PR)
