40 tickets were sold for a concert, some at 75 cents and the rest at $1.25. if the total raised was $42, how many had the cheaper ticket. please i need this for an assignment​

Answers

Answer:

34

Step-by-step explanation:

$1.25 = 125 cents.

$42 = 4200 cents

Tickets sold at 75 cents = x

Tickets sold at 125 cents = y

x + y = 40

75x + 125y = 4200

Multiply the first equation by 75

75x + 75y = 3000

75x + 125y = 4200

Subtract the the second equation from the first.

75x + 75y = 3000

- 75x + 125y = 4200

-------------------------------

0 - 150y = - 1200

Divide both sides by - 150

-150y/-150 = -1200/-150

y = 8

Substitute y = 8 into the first equation

x + y = 42

x + 8 = 42

x = 42 - 8

x = 34

34 tickets were sold for 75 cents

8 tickets were sold for $1.25

8 Rotate the point (-3,-4) around the origin 180 degrees. State the image of the point.
A (-4,-3)
B (-4,3)
C (4, -3)
D (3, 4)

Answers

Answer: D (3,4) trust and believe

brainlyst pls I think I spelt is wrong

Step-by-step explanation:

When a line or shape or point is rotated, it must be rotated around a point.

The image of the point is D. (3,4)

The point is given as:

[tex]\mathbf{(x,y) = (-3,-4)}[/tex]

A 180-degree rotation across the origin is represented as:

[tex]\mathbf{(x,y) \to (-x,-y)}[/tex]

Substitute values for the coordinates of the point (x,y)

[tex]\mathbf{(-3,-4) \to (-(-3),-(-4))}[/tex]

Simplify

[tex]\mathbf{(-3,-4) \to (3,4)}[/tex]

Hence, the image of the point is D. (3,4)

Slope intercept form of 4x+4y=-32

Answers

Answer:

y = - x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

4x + 4y = - 32 ( subtract 4x from both sides )

4y = - 4x - 32 ( divide all terms by 4 )

y = - x - 8 ← in slope- intercept form

Answer:

x+y=-8

Step-by-step explanation:

-32=4x+4y

-4y=4x+32

y=(4x+32)/-4

y=-x-8

x+y=-8

Now comparing to slope intercept form

y=mx+c,we get

slope =1

y intercept =1

y=-8

The are of a circle is given as :

Area = pi(d²) /4

Area = 1110.4in²

1110.4 = 3. 14 * d² / 4

1110.4 * 4 = 3.14 * d²

4441.6 = 3.14d²

d = 37.600

d = 37.6

The equation of the piecewise function f(x) is below. What is the value of f(3)?

Answers

Answer:

5

Step-by-step explanation:

Ask your self which equation you should use. Since it says F(3) then we have to find an equation that would fit this correctly. For example if we look at -X^2, X<-2 we could see that 3 is clearly not less than -2, leading to the conclusion that this is not the right equation.. If you look at the last equation it says that x has to be greater/equal to 0 which is true. So then we are left with the equation...

F(3)=x+2

F(3)=3+2

F(3)=5

How to calculate the third party discounts?

Third party discount is the multiplication result of the maturity value of the original rate to the rate of interest and time period.

Thus, we get:

Third party discount = Maturity value × R × T (R in decimal form).

We have been given that a shirt that normally costs $19.99 is on sale for 15% off. we are asked to find the discount on the shirt.

Therefore,

19.99 x 15/100

19.99 x 0.15 = 2.99

Then subtract from the total amount;

19.99 - 2.99 = 16.99

Therefore, the  shirt cost after the discount will be $16.99. thus option C is correct.
