simplify the expression -2 + 15

Answer:

−13.11

Step-by-step explanation:

Simplify the expression.

− 13.11

Answer:

-13.11

Step-by-step explanation:

Remember: Please Excuse My Dear Aunt Sally (PEMDAS)

You use the parentheses first, so it is 18.03-3*(20.76)÷2

So then, you see there are no exponents, so you multiply and divide from left to right. So, 18.03-62.28÷2. Then you divide: 18.03-31.14

Then, you subtract from left to right, which gives you: -13.11

Step-by-step explanation:

The dimensions of the rectangle ABCD is 24 x 16

The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.

Perimeter P of rectangle = 2 ( Length + Width )

Given data ,

Let the dimensions of the rectangle be represented as L x W

where L and W are the length and width of the rectangle

The perimeter of the rectangle P = 80

Now , measure of side E F of triangle is given by the Pythagoras Theorem

And , E F = √ ( A F )² - ( E A )²

On simplifying the equation , we get

The measure of side E F = √ ( 625 - 400 )

The measure of side E F = √225 = 15

Now ,

The measure of side EC of triangle is given by the Pythagoras Theorem

And , EC = √ ( E F )² - ( C F )²

On simplifying the equation , we get

The measure of side E C = √ ( 15 )² - ( 9 )²

The measure of side E C = √ ( 225 - 91 )

The measure of side E C = √144

The measure of side E C = 12

So , the length of the rectangle B C = E B + B C = 12 + 12

The length of the rectangle B C = 24

The width of the rectangle is A B = W

Perimeter P of rectangle = 2 ( Length + Width )

Substituting the values in the equation , we get

80 = 2 ( 24 + W )

Divide by 2 on both sides of the equation , we get

24 + W = 40

Subtracting 24 on both sides of the equation , we get

W = 16

Hence , the dimensions of the rectangle is 24 x 16

Answer:

2x - 30

Step-by-step explanation:

You have to subtract 3x + 18 from 5x - 12:

=> 5x - 12 - ( 3x + 18) = 5x - 12 - 3x - 18 = 5x - 3x - 12 - 18 = 2x - 30

The first step was to apply distributive properties to get rid of the parenthesis, after that the terms were arranged and the like terms combined

Answer:

Step-by-step explanation:

We use a for Adult and s for Student.

Assuming this, you have to start by writing two equations from the information provided:

900 total tickets were sold    

       a+s=900                             ------(i)

they made $2,820 and  adult tickets cost $4 and kids tickets cost $2.50

      2820=4a+2.5s                    ------(ii)

lets solve for a in the first equation:

a=900-s                      

we can plug this into the second equation and solve for s

2820=4(900-s)+2.5s

2820=3600-4s+2.5s

2820=3600-1.5s

-780=-1.5s

s=520

we can plug this into the first equation and solve for a:

a+520=900

a=380

Total adult ticket sold : 380

Total student ticket sold = 520

Cost of adult tickets = 380 * 4 = $1520

Cost of student tickets = 520 * 2.5 = $1300

Based on the information, it can be inferred that the difference in the circumference of the two circles is 6.31 cm.

To calculate the circumference of a circle we must apply the following formula:

According to the previous formula, we must replace R with the radius of each of the radii of both circles as shown below:

So, to find the difference of the circumferences of both circles we must subtract the smaller number (circumference of the small circle) from the larger number (circumference of the large circle).

According to the above, the difference of the circumferences would be 6.31 cm.

To calculate the area of the circle we must apply the following formula.

How to calculate the circumference of a circle?

To calculate the circumference of a circle we must apply the following formula:

2R

R = Radius of the circle.

According to the previous formula, we must replace R with the radius of each of the radii of both circles as shown below:

So, to find the difference between the circumferences of both circles we must subtract the smaller number (circumference of the small circle) from the larger number (circumference of the large circle).

12.59 - 6.28 = 6.31

According to the above, the difference in the circumferences would be 6.31 cm.

Answer:

225 and 243.4

Step-by-step explanation:

Area of triangle = bh/2

A = 4*4.6/2

A = 9.2 cm sq

A of 2 triangles = 9.2*2 = 18.4 cm sq

Now, Area of 1 rectangle = lb --> 15*5 = 75 cm sq

A of 3 rectangles = 75*3 = 225 cm sq

Now, LSA = 225 cm sq. (excluding the triangles)

TSA = A of tr. + A of rec. = 18.4 + 225 = 243.4 cm sq

Answer:

Clara will have 40 centimeters of ribbon left.

Step-by-step explanation:

1 meter is the same as 100 centimeters, so 2 meters is 200 centimeters. So, we take 200 centimeters, subtract 60 centimeters:

\(200 - 60= 140\)

so she has 140 centimeters, then we subtract another 60 centimeters for Clara's kite:

\(140 - 60= 80\)

But remember, she needs an extra 40 centimeters because her kite is bigger:

\(80 - 40= 40\)

So, Clara is left with 40 centimeters, or 0.4 meters, of ribbon.
