Answer:
8763
Step-by-step explanation:
Let x represent the number of students the college had last year. Then this year's enrollment is ...
... x - 3%·x = 8500
... x(1 - 0.03) = 8500 . . . . . collect terms
... x = 8500/0.97 ≈ 8762.89 . . . . divide by the coefficient of x
Enrollment last year was about 8763.
_____
Of course, you know 3% = 3/100 = 0.03.
Answer:
D
Step-by-step explanation:
if you look at the graph you can see that if you add 2 each tie to a problem it will not go left but right because right means the value is going up and left means the value is going down
Answer:
26
Step-by-step explanation:
h represents highschool members
m represents middle school members
42 = h+m
h = 2m-6
Substitute h for 2m-6 in first equation:
42 = (2m-6)+m
Solve for m:
42 =3m-6
48 = 3m
m = 16
Subsitute 16 for m in second equation:
h = 2(16)-6
Solve for h:
h = 32-6
h = 26
Answer:
The distance between the two points is 10.63015
D=10.63015
The option second -4.9 m/s² is correct the negative sign shows that a positive direction "upward along the ramp".
<h3>What is mass?</h3>
A tangible body's mass is the amount of matter it possesses. It's also a metric of inertial, or the resistance to velocity when a net force is exerted.
The question is incomplete.
The complete question is:
A box that has a mass of 80 kg slides down a ramp with a 30-degree angle. The free-body diagram shows the forces acting on the box. Ignoring friction and air resistance, what is the acceleration of the box, to the nearest tenth?
-0.5 m/s²
-4.9 m/s²
-8.5 m/s²
-9.8 m/s²
First we calculate the weight:
W = mg = 80×9.8
W = 784 N
The weight component parallel to the ramp is:
W₁ = Wsin30
W₁ = (784)(sin30)
W₁ = 392 N
From the Newton's second law:
a = F/m
a = 392/80
a = 4.9 m/s²
Thus, the option second -4.9 m/s² is correct the negative sign shows that a positive direction "upward along the ramp".
