Answer: 150-170 free throws

Step-by-step explanation:

200 times 80% or .8 will give you 160

5% of 200 is 10 so add and subtract that to/from 160 and you'll get your range

What is the height of the tv and is it square inches or inches ??

fiasKO [112]

To find the height of the TV you first need to realize that the question is giving you dimensions for a triangle.

Every triangle has a hypotenuse and two sides. To find the hypotenuse you square both sides, add them, and then square root. So to find one of the sides you get the hypotenuse, square it, and subtract the square length of the given side.

The equation is 25^2-20^2.
Which if simplified is 625-400, the then solution is going to be 225.
You next will square root 225, 225^(1/2). Which your answer should be 15 inches for the missing side length.

7) Una epidemia mató los 3/7 de las vacas de un granero y de las que le quedaron vendió 1/2. Si todavía le quedaron 24 vacas, ¿C

4vir4ik [10]

Answer:

Habían inicialmente 84 vacas. Murieron 36 vacas. 24 vacas fueron vendidas.

Step-by-step explanation:

Sea $x$ la cantidad inicial de vacas. De acuerdo con el enunciado, murieron tres séptimos de la cantidad inicial y la mitad de ese remanente fue vendida, quedando 24 vacas. Matemáticamente, tenemos las siguientes operaciones:

Cantidad inicial de vacas

$x = \frac{24}{\left(1-\frac{3}{7} \right)\cdot \left(1-\frac{1}{2} \right)}$

$x = 84$

Habían inicialmente 84 vacas.

Cantidad de vacas muertas

$y = \frac{3}{7}\cdot x$

$y = 36$

Murieron 36 vacas.

Cantidad de vacas vendidas

$z = \left(1-\frac{3}{7} \right)\cdot \frac{1}{2}\cdot x$

$z = 24$

24 vacas fueron vendidas.

Last month maria purchased a new cell phone for $500. the store manager told her that her cell phone would depreciate by 70% eve

Aleksandr-060686 [28]

We have been given that last month Maria purchased a new cell phone for $500. The store manager told her that her cell phone would depreciate by 70% every 6 months.

We know that an exponential function is in form $y=a\cdot (1-r)^x$ , where,

y = Final value,

a = Initial value,

r = Decay rate in decimal form,

x = Time in years.

Let us convert $70\%$ into decimal form.

$70\%=\frac{70}{100}=0.70$

Initial value of car is 500, so $a=500$ .

Since value of phone depreciates every months, so value of phone will depreciate twice in a year.

Upon substituting our given values in exponential decay function, we will get:

$V=500(1-0.70)^{2x}$

To find the value of phone after 2 years, we will substitute $x=2$ in our equation.

$V=500(1-0.70)^{2(\cdot 2)}$

$V=500(1-0.70)^{4}$

Therefore, option D is the correct choice.

Let us simplify our equation.

$V=500(0.30)^{4}$

Therefore, option B is correct as well.
