Answer:
2 students.
Step-by-step explanation:
add together all of the students and then subtract that from 40.
20+15+3 = 38
40-38 = 2
Answer:
How far did the ship travel between the two observations of the lighthouse = 9.29
Step-by-step explanation:
the first step to answer this question is drawing the illustration as the attachment.
P is the ship, R is the light house and Q is the bearing.
PR is the distance between the ship and the light house, PR = 10.5
∠P = 42.8°, ∠Q = 59.7°
Thus, ∠R = 180° - ∠P - ∠Q
= 180° - 42.8°- 59.7°
= 77.5°
PQ is the the distance of the ship moving. We can use the sinus equation
= 
= 
PQ = (
)(sin 59.7°)
= 9.29
8x-12=36
Let's solve your equation step-by-step.
<span><span><span>8x</span>−12</span>=36
</span>Step 1: Add 12 to both sides.
<span><span><span><span>8x</span>−12</span>+12</span>=<span>36+12
</span></span><span><span>8x</span>=48
</span>Step 2: Divide both sides by 8.
<span><span><span>8x/</span>8</span>=<span>48/8
</span></span><span>x=6
</span>Answer: x=6
B=number of ticets sold before
a=number of tickets sold after
cost of a ticket=number of tickets times cost per ticket
beforecost=39.95b
aftercost=54.95a
total cost=925000
39.95b+54.95a=925000
total number tickets=20000
b+a=20000
we have
39.95b+54.95a=925000
b+a=20000
multiply second equation by -39.95 and add to first equatin
39.95b+54.95a=925000
<u>-39.95b-39.95a=-799000 +</u>
0b+15a=126000
15a=126000
divide bot sides by 15
a=8400
sub back
b+a=20000
b+8400=20000
minus 8400 both sides
b=11600
11,600 tickets sold before
8400 tickets sold after
Answer:
Step-by-step explanation:
so basically you have to look for the opposite side of what they give you. then just plot it in
