In similar figures sides are in proportion

The sides of the bigger parallelogram are x+8 and 20

The sides of smaller parallelogram are x and 12

The sides are in proportion

$\frac{x+8}{x} =\frac{20}{12}$

We can solve this for x

To solve for x we cross multiply

20x=12(x+8)

20x=12x+96

Subtracting 12x both sides

20x-12x=96

8x=96

Dividing both sides by 8

x=12

Beth and her sisters are going to the state fair. Each ride costs $7, and each exhibit costs $4. The table shows the number of r

Maru [420]

Answer:

7x + 3y </=8

Step-by-step explanation:

Let x represent the number of rides Beth rides and y represent the number of exhibits she views

Each ride costs $7 to ride and each exhibit costs $3 to view

This means that x rides will cost x × 7 = $7x

Also, if she views y exhibits, the cost will be y × 3 = $3y.

Total cost of x rides and y views will be 7x + 3y

if she has at most $98 to spend at the fair, it means that all she can spend must be lesser than or equal to $98

The required expression will be

7x + 3y </=8

Party planners recommend that, for every eight guests, two orders of appetizers be provided. Which function reflects this ratio?

Bond [772]

STEP - BY - STEP EXPLANATION

What to find?

The function that reflects the given ratios given.

Given:

For every eight guests, 2 orders.

To determine the function;

Let y be the number of orders and x be the number of guests.

If for every eight guest, there must be 2 orders, then we will have;

$y=\frac{1}{4}x$

So that, if there are 8 guests, that is; when x=8

$y=\frac{1}{4}(8)=2$

ANSWER

y= 1/4 x
