Karina bought a camera with a regular price of $89. It was on sale at a 20% discount. There was a 7% tax on the sale price. How much did Karina spend to buy the camera?

Answers

Answer 1

Answer: 1) we can calculate the price of this camera with 20% discount.
$89-(20/100)($89)=$89-0.2($89)=$89-$17.8=$71.2

2) now, we apply the tax on the sale price.
$71.2 + (7/100)($71.2)=$71.2+(0.07)($71.2)=$71.2+$4.984=$76.184

Answer: Karina spent to buy the camera $76.184.

Answer 2

Answer:

Answer:

$17.18

Step-by-step explanation:

you can't have $17.184 it has to be two deci.

-What is the midpoint between the points (7, 3) and (-5, 5)?

Answers

Answer:

The midpoint is ( 1,4)

Step-by-step explanation:

To find the x coordinate of the midpoint add the x coordinates of the endpoint and divide by 2

( 7+-5)/2 = 2/2 =1

To find the y coordinate of the midpoint add the y coordinates of the endpoint and divide by 2

( 3+5)/2 = 8/2 =4

The midpoint is ( 1,4)

A sine function can be used to model light waves. Green light has a wave length, or period of about 520 nm. Which equation best models green light?A.) y=sin 260/pi theta

B.) y= sin pi/520 theta

C.) y= sin 520/pi theta

D.) y= sin pi/260 theta

Please help

Answers

Answer:

$y = A sin (kx \pm wt)$

Where k represent the number of wave $k =(2\pi)/(\lambda)$ and $w =(2\pi)/(T)$ represent the angular frequency with T the period.

For this case we know tha T = 520 nm

And the angular frequency would be given by:

$w = (2\pi)/(520)= (pi)/(260)$

So then the possible anwer for this case would be:

D.) y= sin pi/260 theta

Since is the only option with satisfy the general equation of a wave.

Step-by-step explanation:

Since the sine function can be used to model light waves we can use the following general expression:

$y = A sin (kx \pm wt)$

Where k represent the number of wave $k =(2\pi)/(\lambda)$ and $w =(2\pi)/(T)$ represent the angular frequency with T the period.

For this case we know tha T = 520 nm

And the angular frequency would be given by:

$w = (2\pi)/(520)= (pi)/(260)$

So then the possible anwer for this case would be:

D.) y= sin pi/260 theta

Since is the only option with satisfy the general equation of a wave.

Question 1 (1 point)Find the coordinates of point P that divides the directed line segment from A to B in the given ratio. A(1, 2), B(5, 4), 1 to 1

Answers

Answer:

P ( -1, -3)

Step-by-step explanation:

Given ratio is AP : PB = 3 : 2 = m : n and points A(5,6) B(-5,-9)

We will calculate coordinates of the point P which divides line segment AB in the following way:

xp = (n · xa + m · xb) / (m+n) = (2 · 5 + 3 · (-5)) / (3+2) = (10-15) / 5 = -5/5 = -1

xp = -1

yp = (n · ya + m · yb) / (m+n) = (2 · 6 + 3 · (-9)) / (3+2) = (12-27) / 5 = -15/5 = -3

yp = -3

Point P( -1, -3)

Determine the area of the regular hexagon

Answers

Answer:To determine the area of a regular hexagon, we need to use the formula:

Area = (3√3 * s^2) / 2

Where:

- s represents the length of one side of the hexagon.

In the given question, the side length of the regular hexagon is not provided. Therefore, we cannot calculate the exact area without that information.

However, if we assume the side length is 7.79 meters, we can substitute it into the formula to find the area:

Area = (3√3 * (7.79)^2) / 2

Area = (3√3 * 60.6641) / 2

Area ≈ 104.434 square meters (rounded to three decimal places).

Again, please note that this answer assumes the side length of the hexagon is 7.79 meters. If the actual side length is different, the area will also be different.

WHAT IS 3/8 DIVIDED BY 1/2

Answers

Answer: 3/4

Step-by-step explanation: Dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the divison sign to multiplication and flip the second fraction.

So here, 3/8 divided by 1/2 can be rewritten as 3/8 × 2/1.

Now we are simply multiplying fractions so we multiply across the numerators and we multiply across the denominators.

So we have 3 × 2 which is 6 and 8 × 1 which is 8. Since 6/8 is not in lowest terms, we divide the numerator and the denominator by the greatest common factor of 6 and 8 which is 2 and we get the equivalent fraction 3/4.

Therefore, 3/8 divided by 1/2 is 3/4.
