Answer:

5 cents each

Step-by-step explanation:

1.00 $ is equal to 100 pennies, so 100 ÷ 20 is 5, to check 5 cents times 20 is 100 cents or 1.00 $

Answer:

c) f(x) = (4ln(x²))/(e ²)

   g(x) = e ^ ((e ² * x)/8)

Step-by-step explanation:

1- Length of PQ: 233

2-Area of rectangle: 21840

3- Length of RS: 241.87

4-Area of triangle: 12600

to find the lengths of RS and PQ use the pythagorean theorem [tex]a^{2} +b^{2}= c^{2}[/tex]

to find area of triangle use [tex]A= \frac{BxH}{2}[/tex] (area = base times height divided by 2)

to find area of rectangle use[tex]A= LxW[/tex] (area= length times width

Answer:

25 feet by 4 feet

Step-by-step explanation:

Answer:

This shape is an irregular polygon. This means we have to find the area of the whole shape and then subtract the missing parts to get the correct answer.

First, we have to find the area of the whole shape (a rectangle). The formula for a rectangle's area is:

The length of the shape is 19 ft, and the width is 29 ft. Now, we apply the formula to those numbers:

Now that we know that the area of the whole polygon is 551 square feet, we have to find the area of:

1. The first missing triangle

2. The second missing triangle

3. The missing rectangle

Add all of those areas together, and then subtract them from 551 and we have the answer.

First, we find the area of the missing triangle in the top left hand corner. The area formula for a triangle is

So, we have to find the base and the height. We see that part of the whole polygon's width is 4 ft, which is not missing, so we subtract that from the total width, 19 ft.

This means that the triangle's base is 15 ft. Now, we have to find the height. We can easily see that the height is 15 ft, as it says so in the picture.

Now, we just have to apply the formula:

So, we have our first area, 112 square feet.

Now we have to find the area of the second missing triangle in the bottom right corner.

We know that the base is 4 ft, as it says so in the picture. The height is 24 ft. We know that the total height of the polygon is 29 ft, and we see a shaded part of 25 ft in height. So:

According to this equation, we have 4 ft in height. Using the area formula for triangles, here is our equation:

This equation states that our second area is 8 square feet.

Now, we just have our last area to find, the missing rectangle. According to all of the previous information, and the picture, we see that the width is 15 ft and the height is 14 ft. Now we apply the area formula for rectangles:

Lastly we add up all of our areas: 112.5 square feet, 8 square feet, and 210 square feet.

Then, we subtract 330.5 from 551:

​​The answer is 220.5

1. Refer to the picture

Answer: it’s option 3

Step-by-step explanation:

y = -1/2x + 2 is the correct answer

Answer:

13/24

can't be simplified

Step-by-step explanation:

you can make them have the same denominator by multiplying.

denominator of 24 is 8*3

and 3*8

then multiply their numerators by the same values

7/8 times 3= 21/24

1/3 times 8= 8/24

subtract

21-8= 13

so 13/24

Answer:

30 hens, 20 cows.

Step-by-step explanation:

Step one:

let the number of cows be x

and the number of hens be y

Each cow has 2 eyes, each hen has 2 eyes also.

the total number of eyes is

2x+2y

Each cow has 4 legs, each hen has 2 legs.

the total number of legs is

4x + 2y

Step two:

the number of legs exceeds the number of eyes by 40:  

4x+2y - (2x+2y) = 40

open bracket

4x+2y-2x-2y=40

4x-2x=40

2x=40

Divide both sides by 2

x=40/2

x=20

Step three:

we know also that x = 2/3*y, so y = 3/2*x = 3/2 * 20 = 30

30 hens, 20 cows.

Check:

60 + 40 eyes = 100, 60 + 80 legs = 140legs.

Answer: See explanation

Step-by-step explanation:

You didn't give the options but let me help out.

First, we need to convert 2 2/3 hours to minutes. This would be:

= 2 2/3 × 60 minutes

= 8/3 × 60 minutes

= 160 minutes

Since water goes over a waterfall at a rate of 162 1/2 gallons every 15 minutes. The the gallons of water going over the waterfall in 2 2/3 hours would be:

= (162 1/2 × 2 2/3hours) / 15 minutes

= (162 1/2 × 160) / 15

= 1733 1/3 gallon
