PLEASE HELP {It costs 5,700 every one sixth of an hour to build a hotel how many cents does building a hotel cost per second?}

Answers

One sixth of an hour is 10 minutes.
That means it costs 5,700 every 10 minutes.

Costs 5,700 = 10 minutes

Dive 10 on both sides.

Costs 570 = 1 minute

Lets convert the minute into seconds.

Costs 570 = 60 seconds

Divide both sides by 60.

Costs 9.5 cents = 1 second

Round it off since you can't pay 9.5 cents.

Costs 10 cents = 1 second

This means that every second they pay 10 cents for the hotel. :D

One serving of granola provides 4% of the protein you need daily. You must get the remaining 48 grams from other sources. How many grams of protein do you need daily?

Answers

If you already have 4% then that means that the other 48 grams is 96%.
So if you make a proportion with 96/100 and 48/x (x being a stand-in for the answer) you can cross multiply 48 and 100 and divide the end result by 96, which equals 50.
So that means that the answer is 50 grams of protein. Hope this helped!

Surface area is much easier then area in this case.

You would just find the area of each side, and since you know the slant height, if you were to take each side of the pyramid as a 2D figure, the base would be 6.4 inches as stated and the height 6.1, because if you look at where the slant height is and basically took a side as a 2D figure, it would be the same as the height.

Pretty sure most people know how to find the area of a triangle, but it's base * height / 2, or 6.4 * 6.1 / 2, or 19.52. Since there are four of these triangle side things, just multiply 19.52 by 4, to get 78.08.

There's still a square base, so just multiply 6.4 by itself to get 40.96.

Now just add the two together to get 119.04.

On a coordinate grid, the coordinates of vertices P and Q for Polygon PQRS are P(3, 2) and Q(−3, 2). What is the length of Side PQ of the polygon?

Answers

The length of the side is the distance between the two points. The distance between two points is:

d^2=(x2-x1)^2+(y2-y1)^2, so in this case:

d^2=(-3-3)^2+(2-2)^2

d^2=(-6)^2+0^2

d^2=36

d=√36

d=6 units.

Note we could have just observed that the y-coordinate did not change and know that the distance between the two points or the length of the sides was just the change in x: 3--3=6 units.

because the angles in a rectangle are 90 degrees it is not a parallelogram true or false? please explain why

Answers

A parallelogram is a 4-sided shape where opposites sides are parallel. A rectangle is a special case of a parallelogram. All rectangles are parallelograms.

But a rectangle is a shape where opposites sides are parallel *and* all the corners are 90 degree angles. So you can't say that all parallelograms would be rectangles. Some parallelograms would be rectangles, but not all.

Rectangles are a subset of the shapes called parallelograms. But parallelograms are *not* a subset of the shapes called rectangles.

It's similar to saying all cars are vehicles. But you can't say that all vehicles are cars.

what is the product of any integer and -1

Answers

the product of any integer and -1 is equals opposite of that integer.

Whenever I have to multiply integers, I think of this little math song to the tune of "Row Row Row Your Boat" that my teacher taught me in 7th grade.

Remember:
Multiply and divide
Then look at the signs
Different signs are negative
Same signs are just fine (positive)

For example: -5 x 5 = -25 -5 x -5 = 25
Different signs Same signs (positive & positive)

So in your specific case, the product of any integer and -1 depends. If the integer is positive, than the final product would be the integer in it's negative form. If the integer is negative, than the final product would be the integer in it's positive form.

I hope this makes sense to you!

How do variables help you model real-world situations? Give an example of a model that uses variables and explain how it helps people make predictions.

Answers

How I use Variables is when i get my pay i get paid 7.50 a hour and work 40 hours a week x=40 Hope this helps =^)

An example would be the order of the ladder.

You are given 4x-2y=12 and -4x-9=54. You are asked to find the order of the ladder. However, you did not specify which variable represents the ladder. I will just solve for both of the variables. I will be applying the substitution method.

Let 4x-2y=12 equals equation one and equation 2 for -4x-9=54.

4x-2y=12

4x=12+2y

x=3+1/2y

substitute this x to the equation 2

-4x-9y=54

-4(3+1/2y )-9y=54

Y=-6

X=3+1/2y = 3+1/2(-6) = 3+(-3) = 0

How long is a distance of 8 km if measured on a map with a scale of 1:50,000

Answers

Since this is a ratios and proportions problem, you would set up the equation like this:
1/50,000 = x/8 x is the length of the distance on the map

After that, you cross multiply and you will get 50,000x=8
You then solve for x to get 0.00016

Final answer:

To find the map distance of an 8 km actual distance on a map with a scale of 1:50,000, convert 8 km to meters (8,000 m), and divide by the scale factor (50,000) to get the map distance of 16 centimeters.

Explanation:

To calculate the length of an 8 km distance on a map with a scale of 1:50,000, you can use the formula:
Actual distance (in real life) / Scale = Distance on the map. This can be rearranged to: Distance on the map = Actual distance / Scale. Therefore, 8 km / 1:50,000 conversion would be calculated as follows:

First, convert the actual distance to the same units as the scale, if necessary. Here, both are in kilometers, so no conversion is necessary. 8 km is equivalent to 8,000 meters.Next, divide the actual distance by the scale factor. So, divide 8,000 meters by 50,000.This results in 0.16 meters or 16 centimeters on the map.

The distance of 8 km is represented as 16 centimeters on a map with a scale of 1:50,000.

Darren and Latisha are decorating cupcakes for a bake sale. They need to decorate 100 cupcakes. Each of them has decorated 40% of the cupcakes. What percentage of cupcakes do they have left to decorate?

Answers

Since they have both decorated 40%, they have decorated a total of 80% of the cupcakes.

They only need to decorate 20% of the cupcakes left.

Answer:

Now they have left to decorate 20% cupcakes.

Step-by-step explanation:

Darren and Latisha are decorating cupcakes for a bake sale.

They need to decorate 100 cupcakes.

Each of them has decorated 40% of the cupcakes = 40% + 40% = 80%

Both of them has decorated 80% of the cupcakes.

80% of 100 cupcakes = 80 cupcakes

Now they have left to decorate 100 - 80 = 20

Now they have left to decorate 20% cupcakes.
