The price of a computer is first reduced by 10% and after a while by another 20%. Who is right? Explain how you are thinking.

Almir: In total, the price has been reduced by 30%.

Bodil: The reduction is less than 30%. Viktor: The price has been reduced by more than 30%.

if u reduced the price by 10% first it would go from 100% to 90%

20% of 90 is 18

at the end the price is 72% of the original price.

Bodil is correct. The reduction is less than 30%.

What number is halfway between 6.7 and 11.9

**Answer:**

2.05

**Step-by-step explanation:**

To find the Median value, we begin by sorting Or arranging our numbers In ascending Or descending order.

-8.8,-5.7,-2.6,0.5,3.6,6.7,9.8,11.9

Having an even (8) number of values, the median is the midway point between the two middle numbers.

In our case the two middle numbers are 0.5 and 3.6

(0.5+3.6)/2

Median=2.05 (In words: two && 5/100)

What is the sine rule

**Answer:**

Sine, in a right triangle, is the side opposite to the angle divided by the hypotenuse.

Law of sines (on any triangle) is

[tex]\frac{sin(A)}{a} =\frac{sin(B)}{b} =\frac{sin(C)}{c}[/tex]

where A, B, and C are angles and a, b, and c are side lengths opposite to the angles.

**Answer:**

sine rule states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in a given triangle.

**Step-by-step explanation:**

In a triangle with sides a,b,c:

a/sin A = b/sin B = c/sin C

What is the answer for this one: If the temperature is 3 degrees and it falls by 12 degrees, what is the new temperature?

**Answer:**

-9 degrees

**Step-by-step explanation:**

3-12=-9

**Answer:**

-9 degrees

**Step-by-step explanation:**

Just think it through. If it's currently 3 degrees out side and then the temperature drops another 12 degrees, what will the temperature be.

If you're still having trouble visualizing it, picture it on a number line. It becomes:

3-12 = ?

(x,y)=(1.5,5.5)Luis has 3 pounds of ground turkey to make turkey burgers. He uses 3/8 pound per burger to make 6 burgers. How many 1/4 pound burgers can Luis make with the remaining turkey?

**Answer: he can make 3 1/4 pound burgers.**

**Step-by-step explanation: we know that he starts with 3 lbs of burger meat, and uses some of the meat to make 6 burgers that each weigh 3/8 lbs. If you take the 3/8 lbs and multiply by 6 burgers, you get 18/8, which is how much has been used so far. If you subtract 18/8 from the 3 lbs that Luis has originally started with, you get 6/8 lbs, which is how much he has after his first 6 burgers. Then you can take the 1/4 and see how many times it fits into 6/8 (1/4=2/8, 6/8 divided by 2/8 = 3 burgers that each weigh 1/4 lbs)**

if f(x)=4x + 3 find f^-1(x)

**Answer:**

f^-1(x) = (x-3)/4

**Step-by-step explanation:**

The notation f^-1(x) means that you are finding the inverse of the function f(x). To do this, you'll want to swap the "x" and the "y" in the original function, and then solve for y. Here's how:

First, we take the original function and swap the two variables:

y = 4x + 3

x = 4y + 3

Then we subtract 3 from both sides

x - 3 = 4y

Then to get y on its own, we divide both sides by 4.

y = (x-3)/4

Make sure to note that the whole expression x-3 is divided by 4, not just one part of it.

So your new inverse equation is:

f^-1(x) = (x-3)/4

**Answer:**

**y = (1/4)(x - 3) is the desired inverse function of f(x) = 4x + 3.**

**Step-by-step explanation:**

Here we're finding the 'inverse function' of the given f(x) = 4x + 3. Follow these steps:

1. Replace the label f(x) with y: y = 4x + 3

2. Interchange x and y: x = 4y + 3

3. Solve this new equation for y: 4y = x - 3, or **y = (1/4)(x - 3**

x/4 = 16

**Hi there!**

Since this is a one-step equation, we can solve it in one step.

This step is multiplying both sides by 4 to isolate x:

x=16*4

x=64

Therefore, x=64.

Hope it helps!

~GracefulGirlie

Good luck. :)

**Answer:**

X = 64

**Step-by-step explanation:**

x/4 = 16

Multiply both sides by 4

x = 16 x 4

Multiply 16 and 4 equals 64

C was given when u received the point (0, -12)

so C is -12

**Answer:**

*y = -5/2x - 1 *

**Step-by-step explanation:**

First, we will figure out the slope. We will use the points (0, -1) and (2, -6). To do this, we look at the y values, -1 and -6, and we look at their rate of change. To get to -6 from -1 we subtract 5, or add -5. Now look at x: 0 and 2. To get from 0 to 2, we add 2. Our slope is [tex]\frac{-5}{2}[/tex].

We can use the point (0, -1) because that's our y-intercept. Your y-intercept is the value of y when **x is equal to 0**. Now, we put our slope and y-intercept into the slope intercept equation:

**y = mx + b**: *where **b** is the y-intercept and **m** is the slope*

*y = -5/2x - 1 **is your answer*

Hope this helps! :D

2000*0.25=500

500*0.25=125

...

A, or f(x) = 8,000(1/4)^x

8,000 is our starting number since number of half lives is our x, and at x = 0, remaining amount of substance is equal to 8,000. As we can see on the graph, the number decreases by a quarter of its original value every time. Since the number is not getting bigger, we use a fraction instead of a whole number. Finally, the exponent makes sure that it’s a quarter of the product from before.

A total of 379 tickets were sold for the school play. They were either adult tickets or student tickets. There were 71 fewer student tickets sold than adult tickets. How many adult tickets were sold?

A total of 225 **tickets** were sold to **adults** for the school play.

How many tickets were sold to adults?

In this problem we see the case of 379 **tickets** being sold to **adults** and **students** and there was 71 tickets more sold to adults. This situation is defined by following equations:

x + y = 379

x + 71 = y

Where:

x - Tickets sold to students.y - Tickets sold to adults.Now we proceed to solve the **system of linear equations**:

x + (x + 71) = 379

2 · x = 308

x = 154

And the number of tickets sold to adults is:

y = x + 71

y = 154 + 71

y = 225

Answer:

Speed of the wave in the string will be 3.2 m/sec

Explanation:

We have given frequency in the string fixed at both ends is 80 Hz

Distance between adjacent antipodes is 20 cm

We know that distance between two adjacent anti nodes is equal to half of the wavelength

So \frac{\lambda }{2}=20cm

2

λ

=20cm

\lambda =40cmλ=40cm

We have to find the speed of the wave in the string

Speed is equal to v=\lambda f=0.04\times 80=3.2m/secv=λf=0.04×80=3.2m/sec

So speed of the wave in the string will be 3.2 m/sec
