Kate is going to the fair with three of her friends. It will cost $5.00 to get in and an additional $2 per ride. Create an equat

ion to represent the cost for the whole group and then use the distributive property to expand the expression and solve the problem.
Expression: (4*5)+(2*5)=30
So I have the expression I just need to do the distributive property and I don't understand how to do that.

Answer:

5 * ( 4 + 2 ) = 5 * 6 = 30

Step-by-step explanation:

(5*4) + (2*5) = 20 + 10 = 30

5*4 = 4 people need to pay $5

2*5 = $2 for 5 rides

Distributive Property:

(5*4) + (2*5) = 5 * ( 4 + 2 )

5 * ( 4 + 2 ) = 5 * 6 = 30

Answer:

<h2>$40</h2>

Step-by-step explanation:

Ok, so the distributive property allows us to apply a number evenly over a whole set of numbers.

Equation: 4 (2 x 5) (we distribute the 4 to all terms, since each person experiences those charges.) The answer is $40 for the whole group.

What is the area of this figure? Round to the tenth if necessary.
Julli [10]

Answer:

<h3>b) 850.1 centimeters.</h3>

Step-by-step explanation:

To find the area of this figure, we must first find the areas of the shapes that compose this figure.

This figure is made up of a rectangle and a semicircle.

Remember: To find the area of a semicircle, multiply the radius by itself twice, then multiply the product pi, lastly divide the product by 2.

a=\pi r^2/2

<u>3.14 will be used for pi!</u>

To find the area of a rectangle, multiply the length by the width. The product is the area of the rectangle.

a=lw

Now, let's solve.

The diameter of the semicircle is 32 centimeters.

To find the radius of a semicircle, divide the diameter by 2.

32/2=16

The radius of the semicircle is 16 centimeters.

Now that we have the radius, we can find the area of the semicircle.

\pi 16^2/2=401.92

The area of the semicircle is 401.92 centimeters.

Furthermore, we find the area of the rectangle.

14*32=448.

The area of the circle is 448 centimeters.

Next, we add the areas of both shapes to find the area of this figure.

401.92+448

=849.92

The final step is to round 849.92 to the nearest tenth.

Even though 849.92 to rounded to the nearest tenth is 849.9, there is no answer choice for this. The closest one to this answer is choice 'b.'

I, therefore, believe the area of this figure is 850.1 centimeters.
