Orlando buys a shirt for $15 and a pair of jeans for $32.50. If the sales tax is 8%, what is the total price Orlando pays for the item?

Answers

Answer 1

Answer: $15 + $32.50 + 8% = $51.30

15 + 32.50 = 47.50

8% × 47.50 = 3.80

47.50 + 3.80 = 51.30

Answer 2

Answer: 15+32.50= 47.50 is 100% of the price
0.475 is 1% so 0.475•8= $3.8 is 8%

Total price is 47.50+3.80= $51.30

A packet contain 1.5kilogram of Guinea pig food. Remi feeds her Guinea pig 30 grand of food each day, how many days does the packet of food last

Answers

The number of days the packet of food last is A = 50 days

What is unit conversion?

In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.

The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.

A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.

Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.

Given data ,

Let the number of days the packet of food last be A

And , from the unit conversion

1 kg = 1000 grams

The total amount of food in the packet = 1.5 kilograms

And , the amount Remi feeds her Guinea pig per day = 30 grams

So , number of days A = total amount of food in the packet / amount Remi feeds her Guinea pig per day

On simplifying , we get

A = 1500 / 30

A = 50 days

Hence , the number of days is 50

Do you mean 30 grams? If so you convert 1.5 kilograms to grams. Then divide it by 30. So 1500÷30=50. Hence, the packet of food would last 50 days.

Answers

Answer:

Option A.

Step-by-step explanation:

The given equations are

$2y-2x=12$ ...(1)

$x^2+y^2=36$ ...(2)

From equation (1), we get

$2y=12+2x$

$y=(12+2x)/(2)$

$y=6+x$ ...(3)

Substitute $y=6+x$ in equation (2).

$x^2+(6+x)^2=36$

$x^2+36+12x+x^2=36$

$2x^2+12x=0$

$2x(x+6)=0$

$x=0,-6$

Put x=0, in equation (3).

$y=6+0=6$

Put x=-6, in equation (3).

$y=6-6=0$

It means, (0,6) and (-6,0) are two solutions of the given system of equations.

Therefore, the correct option is A.

The point (-4,1) is totated 180 degrees counterclockwise using center (0,0). What are the coordinates of the image?

Answers

Answer:

Coordinates of the image are (4 , -1)

Explanation:

The rule for 180° rotation counterclockwise is:

(x , y) ⇒ (-x , -y)

This means that to get the coordinates of a point rotated 180° counterclockwise, all you have to do is flip the signs of both the x and the y

Now, we are given the point (-4 , 1)

Applying the above rule:

$\n (x_(image),y_(image)) = (-(-4) , -(1))\n (x_(image),y_(image)) = (4,-1)$

Hope this helps :)

Final answer:

A 180 degrees counterclockwise rotation around the origin (0,0) would flip a point (x,y) to its opposite (-x,-y). Therefore, if you rotate the point (-4,1) 180 degrees counterclockwise, the new coordinates of the point would be (4, -1).

Explanation:

In Mathematics, specifically in Geometry, when we conduct a 180 degrees counterclockwise rotation around the origin (0,0), every point on the plane rotates by 180 degrees in the counterclockwise direction.

For a point (x,y), a 180-degrees rotation would result in the point ending up at (-x,-y).

Therefore, if you rotate the point (-4,1) 180 degrees counterclockwise around the origin, the new coordinates of the point would be (4, -1).
