An element with mass 780 grams decays by 17.1% per minute. How much of the element is remaining after 19 minutes to the nearest
Anit [1.1K]
Step 1
Formulate a recursive sequence modeling the number of grams after n  minutes.
we have that
100%-17.1%-------------- > 82.9%------------> 0.829

a(n) = 780*[0.829<span>^n]
</span>
for n=19 minutes
a(19)=780*[0.829^(19)]=22.1121 g---------------> 22.1 g

the answer is 22.1 g

Kajal holds a ruler in some wavy water. The depth of the water t seconds after she starts measuring it, in cm, is given by D(t)=
Vera_Pavlovna [14]

Answer:

t = 0.77

Step-by-step explanation:

D(t) = 50 - 23 sin(π(t + 0.23))

The value of the sine function has a maximum of -1 and a minimum of 1.

The average value of the sine function is 0.

At maximum sine value:

D(t) = 50 - 23(1) = 50 - 23 = 27

At minimum sine value:

D(t) = 50 - 23(-1) = 50 + 23 = 73

At average sine value of 0:

D(t) = 50 - 23(0) = 50 - 0 = 50

The average depth of the waves is 50 cm.

Now we need to find at what time, t, that occurs.

D(t) = 50 - 23 sin(π(t + 0.23)) = 50

50 - 23 sin(π(t + 0.23)) = 50

-23 sin(π(t + 0.23)) = 0

sin(π(t + 0.23)) = 0

The value of the sine is 0 at 0, π, 2π, ..., nπ

π(t + 0.23) = nπ

t + 0.23 = n

t = n - 0.23

n is all integers, but here we are concerned with the first occurrence after time equals zero, so we want n = 1.

t = 1 - 0.23

t = 0.77

Andre and Elena are each saving money. Andre starts with $100 in his savings
zysi [14]
Andre’s equation is y = 5x + 100 and Elena’s is y = 20x + 10
Andre - 5x + 100 the x is how many weeks (6) so it’ll be 5(6) + 100 which is 30 + 100 = $130 in 6 weeks
Elena - 20x + 10 same thing x is how many weeks (6) as well so 20(6) + 10 which is 120 + 10 = $130 as well in 6 weeks so therefore, the answer is C.

The cost for a pack of 7 padlocks to $23.80. Find the unit price in dollars per padlock. If necessary, round your answer to the
Galina-37 [17]

It asks to "Find the unit price in dollars per padlock"

The phrasing "dollars per padlock" is the same as "dollars per 1 padlock"

In other words, the teacher wants to know how much 1 padlock costs.

7 padlocks : $23.80

7/7 padlocks : $23.80/7 .... divide both parts by 7

1 padlock : $3.40

We see that 1 padlock costs $3.40, so the unit cost is $3.40 per padlock

PLEASE HELPPP dbhwbdbff

Camp Summer Fun will need about 83 tents.

The actual number of tents needed is less than the estimate because 331 divided by 4 is 82.75 and because I rounded to 83 it is less.

Hope this helped :)
