Answer:

C. $7.70

Step-by-step explanation:

First, you have to calculate the 10% of the price and subtract that from the price to find the amount of the discount:

$27*10%=$2.7

Now, you can add the amount of the discount plus the coupon to find the amount that the customer saved:

$5+$2.7=$7.7

According to this, the answer is that the customer saved: C. $7.70

The summer has ended and it's time to drain the swimming pool. 20 minutes after pulling the plug, there is still 45 000L of wate
jek_recluse [69]

Answer:

a) -900 L/min

b) 63000 L

c)  -900t +63000

 d) 7200 L

Step-by-step explanation:

a) You are given two points on the curve of volume vs. time:

(t, V) = (20, 45000) and (70, 0)

The rate of change of volume

= ΔV/Δt = (0 -45000)/(70 -20) = -45000/50 = -900 liters per minute

b) In the first 20 minutes, the change in volume was

(20 min)(-900 L/min) = -18000 L

So, the initial volume was

initial volume - 18000 = 45000

initial volume = 63,000 liters

c) Since we have the slope and the intercept, we can write the equation in slope-intercept form as

 V= -900t +63000.

d) now putting the number in the equation and do the arithmetic.

When t=62, the amount remaining is

= -900(62) +63000 = -55800 +63000 = 7200

Thus, 7200 L remain after 62 minutes.

Given that lim x→2 (4x − 2) = 6, illustrate Definition 2 by finding values of δ that correspond to ε = 0.5, ε = 0.1, and ε = 0.0
e-lub [12.9K]

More generally, let \delta=\frac\varepsilon4. Then

|x-2|

which proves the limit is 6. So

\varepsilon=0.5\implies\delta=0.125

\varepsilon=0.1\implies\delta=0.025

\varepsilon=0.05\implies\delta=0.0125

Which triangles are congruent?plz help!!!!.
Diano4ka-milaya [45]
The right answer is triangles ABC and MNO. Congruent triangles are triangles that have the same lengths of its three sides. To get the length of each side, use the distance formula with equation:
d =  \sqrt{( x_{2} -  x_{1}) ^{2}  +( y_{2} - y_{1} )^2 }

ABC and MNO have the same segment lengths of its correspoding sides:
AB = MN = 8 units
BC = NO = 6 units
AC = MO = 10 units
