Answer:

The club made a profit of $96 from the shirt sale.

Step-by-step explanation:

First, you have to find the number of shirts sold by dividing the total amount sold by the price per shirt:

480/20=24

Now, that you know the number of shirts that were sold, you can multiply the profit per shirt for the number of shirts sold:

4*24=96

According to this, the answer is that the club made a profit of $96 from the shirt sale.

Answer:

Option (D)

Step-by-step explanation:

Standard equation of a quadratic function is,

ax² + bx + c

Comparing this function with the given quadratic function,

f(x) = 2x² - 4x - 3

a = 2, b = -4 and c = -3

By using quadratic formula to get the value of x,

x = [tex]\frac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

  = [tex]\frac{-(-4)\pm \sqrt{(-4)^2-4(2)(-3)} }{2(2)}[/tex]

  = [tex]\frac{4\pm\sqrt{16+24}}{4}[/tex]

  = [tex]\frac{-4\pm \sqrt{40}}{4}[/tex]

  = [tex]\frac{-2\pm \sqrt{10}}{2}[/tex]

Therefore, Susie made a mistake in step IV.

Option (D) is the answer.

the answer is

(x,345)

Answer:

x = 1/2

Step-by-step explanation:

[tex] \frac{4}{7} x = \frac{2}{7} \\ \\ x = \frac{ \cancel2}{ \cancel7} \times \frac{ \cancel7}{ \cancel4 \: \: 2} \\ \\ x = \frac{1}{2} [/tex]

Answer:

The length of each side of triangle is:

First side of triangle = 21 inches

Second side of triangle = 16 inches

Third side of triangle = 28 inches

Step-by-step explanation:

Perimeter of triangle = 65 meters

Let

First side of triangle = x

Second side of triangle = x-5 (The second side is 5 meters less than the first side.)

Third side of triangle = x+7  (The third side is 7 meters more than the first side.)

We need to find length of each side.

The formula used is:

[tex]\mathbf{Perimeter\:of\:triangle=Sum\:of\:all\:sides\:of\:triangle}[/tex]

Putting values and finding value of x

[tex]Perimeter\:of\:triangle=Sum\:of\:all\:sides\:of\:triangle\\65=x+x-5+x+7\\65=3x+2\\Switching\:sides\\3x+2=65\\Subtracting\:2\:from\:both\:sides\\3x+2-2=65-2\\3x=65-2\\3x=63\\Divide\:both\:sides\:by\:x\\\frac{3x}{3}=\frac{63}{3}\\x=21[/tex]

So, We get value of x = 21

Now, finding the length of each side of triangle:

First side of triangle = x = 21

Second side of triangle = x-5 =21-5 =16

Third side of triangle = x+7 = 21+ 7 = 28

The length of each side of triangle is:

First side of triangle = 21 inches

Second side of triangle = 16 inches

Third side of triangle = 28 inches

Answer:

cos[tex](x-\frac{\pi}{2})[/tex]

Step-by-step explanation:

If you insists that sine and cosine should be of the same angle use Pythagorean identity. Otherwise you can use identity sin(x) = cos[tex](x-\frac{\pi}{2})[/tex]

Answer:

1.08

Step-by-step explanation:

Given :

Skies travel charges two-fifty for a plane ticket and $28 per day for rental car.

For the same trip, r&r travels charges 305 for a plane ticket and 23 per day for car rental.

To Find :

The minimum number of days in martin's vacation should be or r&r travel to be a better deal for him.

Solution :

Let, minimum number of days are x.

So, cost charged by Skies travel is, [tex]c_1 = 25+28x[/tex]

Cost charged by r&r travels is, [tex]c_2 = 305 + 23x[/tex]

r&r should be better deal when :

[tex]c_2 < c_1\\\\305 + 23x <25 + 28x\\\\5x >280\\\\x>56[/tex]

So, for better deal at r&r minimum number of vacation days is 57.

Hence, this is the required solution.

because there negatives

Answer: -5 1/2 or -5.5

Step-by-step explanation: Negative five and a half. Its technically -5 2/4 but simplify 2/4 its 1/2

Answer:

Point B is located at -5.5

Step-by-step explanation:

Point B is located at the mid point between -6 and -5 on the scale. So, the answer would be 5 and 1/2 or -5.5
