We can use one formula that has to do with the simple interest add on loan which is: S.I = P * R/100 *T. The simbol S.I is Simple Interest, P is he amount that costs the TV, R is the rate percentage of interest and T is the time of the payment. So the operation will go S.I= 1299*19.25/100*3 and the result is 750.125. This will be the Simple interest and now we are adding the real cost of the TV: 750.125 + 1299 = 2049.17. As the year has 12 months and we are talking about 3 years then 12 months * 3 years will be =36. Then we take the total money and we divide it into 36 and it equals 56.92 which is what they need to pay per month. and now if they pay 800 what will remain will be 1299-800=499 so we do the operation again S.I=p*r/100*T but with the new p=499. So 499*19.25/100*3=288.17 and then 288.17+499=21.8659 =$21.87 and that will be the second answer

You have 480 grams of a radioactive kind of samarium. If its half-life is 90 years,
lisov135 [29]

Answer:

120 grams will be left after 180 years.

Step-by-step explanation:

A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay and its given by

                                             N(t)=N_0(\frac{1}{2})^\frac{t}{t_{1/2}}

where,

N(t) = quantity of the substance remaining

N_0 = initial quantity of the substance

t = time elapsed

t_{1/2} = half life of the substance

From the information given we know that:

  • The initial quantity is 480 g,
  • The half-life is 90 years,
  • 180 years is the time elapsed.

And we want to find how much will be left. For this we use the above formula.

N(t)=480\left(\frac{1}{2}\right)^{\frac{180}{90}}\\\\N(t)=480\left(\frac{1}{2}\right)^2\\\\N(t)=480\cdot \frac{1}{2^2}=120

120 grams will be left after 180 years.

Plz help with 12<br> Will give brainliest
Irina-Kira [14]

Answer:

True, based on the <em>Transitive Property of Equality</em>.

Step-by-step explanation:

Note that the <em>Transitive Property of Equality </em>states that "If a = b, & b = c, then a = c.

In this case it is the same.

∠1 ≅ ∠2 (because both are complementary), ∠1 ≅ ∠3 (again, both are complementary), then based on the Transitive Property, ∠2 ≅ ∠3, making all of them complementary angles
