Answer:
A
Step-by-step explanation:
This is because vertical angles are always congruent, they cross diagonally which makes them equal to each other.
Answer:
E!
Step-by-step explanation:
Answer:
the slope is -1/2 while the y-intercept is 80
Step-by-step explanation:
Let x be the time in minute and y be the water in the gallon.
From the question, the water flows at a rate of 1 gallon every 2 minutes, which implies that, the rate of change is the slope = 1/2.
The tank has a leak i.e The water flows out from the tank. Since the water flows out of the scope,it implies that the scope = -1/2. y- intercept is the initial amount of water in the tank which is 80.
Part A:
Phone A has a $8.75 discount
$175*0.05=$8.75
Phone B has a $40.00 discount
$200*0.20=$40
Part B:
Phone A is $166.25
$175-$8.75=$166.25
Phone B is $160.00
$200-$40=$160
Part C:
Phone B costs less after the discount
Part D:
No, sales tax is applied to the discounted/final price, so both prices will increase by 6%. Phone B will still be cheaper.
V=pi a^2*h
V= 3,14*100*18 cm^3=5652 cm^3
Answer is 5652
