Damian is buying a video game that was just marked 20% off. The original price was
$80. What is the new price of the video game?

Answers

Answer: $64

80(0.20) = 16
80 - 16 = 64

Since it’s a discount, after we multiplied it with 20% (0.20), we need to take the product and subtract it from the original price.

What is the value of x

Answers

Answer:

X = 56 degrees

Step-by-step explanation:

Angles D and F are equivalent. Because the three angles must add up to 180 degrees, you must add 112 to 68 in order to reach 180. Then you must divide this in half, getting 56 degrees as your answer.

180 - 68 = 112

112/2 = 56

X=56

What name is given to each of the following angles?

a) An angle of exactly 90 degrees
b) An angle between 90 degrees and 180 degrees
c) An angle less than 90 degrees
d) An angle between 180 degrees and 360 degrees

Answers

Answer:

Step-by-step explanation:

a) Right angle

b) Obtuse

c) Acute

d) Reflex angle.

Thank you

The name of the angles are as follows:

1) x = 90 degrees: Right angle.

2) 90 < x < 180: Obtuse angle.

3) 90 > x : Acute angle.

4) 180 < x < 360 : Reflex angle.

Given,

Category of angles.

Now,

Right angle : An angle of exactly 90 degrees.

x = 90 degrees

Obtuse angle :

An angle between 90 degrees and 180 degrees.

90 < x < 180

Acute angle:

An angle less than 90 degrees.

90 > x

Reflex angle:

An angle between 180 degrees and 360 degrees.

180 < x < 360

A logarithmic function of base ‘3’ has a vertical asymptote at the line x=1. Its graph contains the point (2,1). What is the equation of the function?
1) f(x)=log3 (x+1)
2) f(x)=log3(x-1)+1
3) f(x)=log3(x+1)+1
4) f(x)=log3(x)+1

Answers

9514 1404 393

Answer:

2) f(x) = log3(x -1) +1

Step-by-step explanation:

The vertical asymptote of the log function is normally x=0. In this function, it is moved to the right 1 unit. That is accomplished by replacing the function argument x with (x-1). Only one answer choice matches:

f(x) = log3(x -1) +1

russell works at a football concession stand selling drinks for $2 and bags of chips for $3

Answers

Answer:

its 5

Step-by-step explanation:

2+3 = 5

-_-

The number of drinks sold by Russell were 54 and number of chip sold were 46.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

Russel sells a total of 100 drinks and bags of chips

C+D=100...(1)

Drinks for $2 and bags of chips for $3.Russell makes a total of $246

3C+2D=$246..(2)

Let us solve above two equations to find the number of drinks and chips sold.

C=100-D (From (1))...(3)

Substitute (3) in (2)

3(100-D)+2D=246

300-3D+2D=246

300-D=246

300-246=D

D=54

Now plug D value in equation (1)

C+54=100

Subtract 54 from both sides

C=100-54

C=46

Hence the number of drinks sold by Russell were 54 and number of chip sold were 46.

At the rodeo, 256 hot dogs were sold for a total of $768. If each hot dog sold for the same amount, what would be the cost of 24 hot dogs?

Answers

Answer:

$72

Step-by-step explanation:

$768/265 = $3

$3 x 24 = $72

Answer:

$72

Step-by-step explanation:

768/256 = how much each hot dog was sold for

768/256 = 3

Each hot dog was sold for $3.

24*3 = $72

Therefore, the cost of 24 hot dogs is $72.

Answers

Answer:

y = (1/3)x

Step-by-step explanation:

1) Use the slope formula: (y2-y1)/(x2-x1) and then substitute both points into the formula. That should give you (2-0)/(6-0) = 2/6 = 1/3.

1/3 would then be your slope

2) Since the y intercept is (0,0), the y-intercept isn't needed in the slope intercept equation

So that would give you y = (1/3)x

Carmen is writing an article for a magazine. She will be paid a flat fee and also will be paid for each word that is published. The total amount she can expect to be paid, in dollars, can be estimated using the function f(x) = 2.5x + 150 . where s is the number of words published . What is the inverse of this function?

Answers

Step-by-step explanation:

Given Function

f(x) = 2.5x + 150

f^-1(x) = ?

Let y = f(x)

y = 2.5x + 150

Interchanging the role of x and y we get,

x = 2.5y + 150

x - 150 = 2.5y

y = (x - 150) / 2.5

So therefore

f^ -1(x) = (x - 150) / 2.5

Hope it will help :)

Step-by-step explanation:

Simplify the algebraic expression by combining like terms.

Answers

Answer:

The answer for the first problem is 10x + 4 and the answer for the second problem is 14x + 6.

Step-by-step explanation:

First problem: 6x - 3 + x + 7 + 3x

First, look at the terms, match the x's with x's and numbers with numbers.

6x + 3x + 1x = 10x

-3 + 7 = 4

So this makes the answer 10x + 4.

Second problem: 2(7x + 3)

All you need to do is distribute the 2 for 7x + 3, meaning that you multiply each of them by 2.

2 times 7x = 14x

2 times 3 = 6

So the answer is 14x + 6.

find the values of m &n .. please help !!

Answers

Answer:

m = 12.728 or 18/root (2)/2, n = 9

Step-by-step explanation:

To find m, we can use sin(45) and cos(45).

Since sin(45) = root (2)/2 and this equals 9/m.

We set the equation root (2)/2 = 9/m and solve for m.

9 divided by root (2)/2 would give us 18/root (2), or 12.728.

m is 12.728.

Same process for n but we are using cosine this time.

cos(45) = root (2)/2 and this equals n/12.728.

Solving for n would give us root (2)/2 times 12.728.

This gives us that n is 9.
