The win-loss record for a football team is 15 wins and 9 losses. What percent of their games did they win?

Burka [1]

Answer:

62.5%

Step-by-step explanation:

To find percentage of win, we simply need to find the number of games won and divide it by the total number of games played. Then we will multiply that answer by 100 (to get percentage).

So,

Number of games won = 15

Total number of games = 15 + 9 = 24

Percentage of Win = $\frac{15}{24}=0.625=62.5$

Answer is 62.5%

A store has a 40% off sale on headphones. With this discount, the price of one pair of headphones in $36. What is the original p

Mariana [72]

Let the original price of headphone = x

there is 40% discount which is 0.40x

so the payment price will be x-0.40x = 0.60x

Given that paid amount is $36

so both will be equal

0.60x = 36

x=36/0.60

x=60

Hence final answer is $60.

Which equation could generate the curve in the graph below?

dimulka [17.4K]

Answer:

The answer is option 1.

Step-by-step explanation:

In order to find the equation, you have to apply Discriminant Law, D = b² - 4ac. When D < 0, the equation has no real roots (no x-intercept). When D = 0, it has 2 and equal roots (1 x-intercept). When D > 0, it has 2 distinct roots (2 x-intercept).

Option 1,

$y = 3 {x}^{2} - 2x + 1$

$D = {( - 2)}^{2} - 4(3)(1)$

$D = - 8$

$D < 0$

Option 2,

$y = 3 {x}^{2} - 6x + 3$

$D = {( - 6)}^{2} - 4(3)(3)$

$D = 0$

Option 3,

$y = 3 {x}^{2} - 7x + 1$

$D = {( - 7)}^{2} - 4(3)(1)$

$D = 37$

$D > 0$

Option 4,

$y = 3 {x}^{2} - 4x - 2$

$D = {( - 4)}^{2} - 4(3)( - 2)$

$D = 40$

$D > 0$

As you look at the graph, the curve does not meet x-axis so the discriminant must be less than 0.

Triangle WXY, with a vertex X at (3, 0), is rotated clockwise 270° about the origin. Which of the following rotations is equival

sergey [27]

What are the answer options?

A rotation of 270 would be equal to 630, 990, etc. Adding 360 degrees would result in the same rotation.

A rotation of 90 degrees counter-clockwise would also result in the same rotation, as would 90 plus any multiple of 360 if rotated counter-clockwise.
