The tennis team is selling tickets to wash for six dollars. And they don't do not sell very much tickets, the team decreases the

schepotkina [342]

Answer:

The new cost of tickets after decrease of price at 23 % rate is $ 4.62

Step-by-step explanation:

Given as :

The initial cost of the selling tickets = $ 6

Let The final cost of selling tickets = $ x

The rate of decrease of ticket price = 23 %

Now,

The final cost of tickets = initial cost of tickets × ( 1 - $\dfrac{\textrm rate}{100}$ )

or, $ x = $ 6 × ( 1 - $\dfrac{\textrm 23}{100}$ )

or, x = $ 6 × $\frac{77}{100}$

∴ x = $ 4.62

So decrease price = x = $ 4.62

Hence The new cost of tickets after decrease of price at 23 % rate is $ 4.62 Answer

What is the value of K

Elan Coil [88]

Answer:

k = 10

Step-by-step explanation:

We first have to get the 3rd angle: 180 - 115 = 65

Sum of angles in a triangle = 180

65 + (4k + 5) + (6k + 10) = 180

Collect like terms

65 + 10k + 15 = 180

80 + 10k = 180

Subtract 80 from both sides

10k = 100

Divide both sides by 10

k = 10

A scientist uses the equation shown below to predict the future population of a species. In the equation, y represents the estim

ololo11 [35]

Answer:

1200

Explanation:

y represents the estimated population

t represents the number of years.

The equation that predicts the population after t years is given as:

$y=150\times4^t$

Substitute t = 3/2 into the equation

$\begin{gathered} y=150\times4^{\frac{3}{2}} \\ y=150\times2^{2(\frac{3}{2})} \\ y=150\times2^3 \\ y=150\times8 \\ y=1200 \end{gathered}$

The closest valuie to the value of y is 1200
