Answer:

O Yes!

Step-by-step explanation:

We would check whether the proportionality of their sides is equal

Taking proportionality

= $\frac{6}{10} = \frac{15}{25}$

Cross Multiplying

6 × 25 = 15 × 10

150 = 150

So, ΔABK is similar to ΔGKY

Answer:

Yes, triangle GYK is similar to triangle BAK.

Step-by-step explanation:

The sides of each triangle are proportional to each other.

Take the longest side of each triangle. You are comparing line AK with line KY.

The proportion is 15/25.

Now, take the shortest side of each triangle. You are comparing line KB with GK.

The proportion is 6/10.

To determine if the triangles are proportional, we can see if the two proportions are equal to each other:

15/20=6/10

3/5=6/10

Correct! 3/5 equals to 6/10. Therefore, the two triangles are similar because their sides are proportional.

Hope this helps :)

The attendance for a team's basketball game can be approximated with the polynomial -5x^2+80x+285, where x is the number of wins

Elan Coil [88]

Answer:

The attendance when the team won 4 games in the previous month is 525

Step-by-step explanation:

The attendance for a team's basketball game can be approximated with the polynomial : $-5x^2+80x+285$

x represents the number of wins the team had in the previous month.

Factor the polynomial :

$-5x^2+80x+285$

$-5(x^2-16x-57)$

$-5(x^2-19x+3x-57)$

$-5(x(x-19)+3(x-19))$

$-5(x+3)(x-19)$

Substitute the value of x = 4

The attendance when the team won 4 games in the previous month = -5(4+3)(4-19)=525

Hence The attendance when the team won 4 games in the previous month is 525

A painting is purchased for $250. if the value of the painting doubles every 5 years, then its value is given by the function v(

nignag [31]

After 5 years, value doubles.
Hence after 5 years, value is 250 x 2 = 500
After another 5 years, value doubles.
500 x 2 = 1000
Ans: $1000

Method 2, using function given.
v(10) = 250 x 2(10/5) = $1000

You owe $1,000 on a credit card that has an interest rate of 27.99% and make only the minimum payment of $20 each month. Which a

mel-nik [20]

Answer: The credit card will paid off within 10 years, therefore the correct option is D.

Explanation:

Let the number of years in which the credit card will aid of be x.

It is given that amount owed on credit card is $1000 with interest rate 27.99%.

So the amount of interest is calculated as,

$1000\times \frac{27.99}{100} =\$27.9$

The total amount have to pay is,

$\$1000+\$279.9=\$1279.9$

The minimum payment is $20 each month.

$x=\frac{1279.9}{20}$

$x=63.995$

So, the credit card will paid of in 63.995 months. We know that 1 year =12 months.

$\frac{63.995}{12} =5.33$

Therefore, the will paid of in 5.33 years, s we can say that the credit card will paid off within 10 years, therefore the correct option is D.
